In-depth analysis: How to accelerate the progress and development of the valve industry

With the rapid development of China's economy, the valve industry, as a national industry, has experienced rapid development for several years and has been rapidly developed throughout the country. It has become one of the fastest growing major industries in the domestic machinery industry. Although China's valve industry has developed rapidly, There are also many problems, low level of development of the industry, low technical content of products, many products are still low-grade; due to the late start of the domestic valve industry, is still in the development stage, valve design, manufacturing, production and testing capabilities are lower than foreign advanced At the same level, many key valves still rely on imports. Many valves do not have core technology. With the level of automation control, there is a certain gap between high-end valve technology and developed countries and foreign countries. What are the reasons for such problems? The following analysis and views, only personal views and ideas, can not help but be correct, for reference only!

Obvious gap between the valve industry, innovation and improvement At present, China's valve industry and the foreign valve industry, the gap is more obvious, but also let us see their own deficiencies, in order to find the gap and the essence of the problem, so as to improve and improve. There are four major comprehensive gaps that the author has learned from the field in the industry and summarized in the analysis. The first is the gap in technological innovation capability; the second is the gap in processing technology; the third is quality management and equipment. The gap is the gap in process management; it can be analyzed from the following aspects.

1. The gap in technological innovation capacity The lack of technological innovation capability is a stumbling block to the development of our valve industry. At present, the design level of China's valve industry is not high. Although domestic backbone enterprises have certain research and development conditions, the majority of valve companies' R&D centers are limited by personnel and facilities, lack sufficient investment in capital, and have relatively closed research and development and technical service capabilities. According to the company's needs and only for corporate services, according to sales orders for the design, process preparation, the function is also relatively simple; such as the valve production process of on-site technical processing, or engaged in a small amount of new product development. Compared with developed countries, there is a big gap between domestic valve design standards.

At present, many domestic valve companies have rarely made innovations after introducing advanced technologies. When overseas customers visited China's heavy industry projects, such as papermaking, petrochemicals, etc., it was found that the valve products of many projects only changed on the basis of Western design prototypes. The processing technology is also relatively backward, although some domestic valve manufacturers have modern equipment that can achieve automatic operation, and even make some Western companies dwarf. However, most companies are outdated equipment and working environment. At present, China's valve companies can cast valve products such as steel, iron, aluminum, copper, and composite materials. However, due to backward casting methods, raw materials such as cast steel and cast iron are wasted in the production process, and environmental protection is also poor.

For example, most manufacturers in China cannot independently perform effective seismic analysis of valves. These manufacturers must entrust design institutes to carry out seismic analysis. Only some manufacturers have mastered the valve stress calculation and seismic analysis, and fatigue analysis of valves. As well as impact analysis, this has, to some extent, constrained the increase in the level of research and development capabilities of domestic manufacturers. Domestic cooperation in production, education, and research is also relatively low, and the technical content of self-developed products is also relatively low, while some institutions of higher learning and research and design institutes have professional, departmental, and chamber-based research on valve technology, but only the valves in the entire device. The role and required characteristics of the proposed technical requirements, and does not start the development of valve product design and manufacturing technology, even if there are design drawings, often lack of technology, and practical operation does not meet, and some of the key due to the lack of practical verification tools, This is the main reason leading to the low overall technical level of domestic valve products.

Valve companies with higher technological standards in foreign countries usually have special R&D centers. In contrast, they have strong funds, various related research institutions, and professional and technical engineering personnel to support them. These R&D centers are often equipped as needed. There are specialized laboratories and testing organizations, and computer application software for valve products is quite complete: theoretical analysis and prediction of advanced performance of new products and new technologies can be performed through analytical means, and experimental methods can be used to predict results. The verification is performed, and the correctness of the analysis method is verified based on the statistical data, and a series of effective valve performance and technical characteristics analysis methods are obtained. Such methods are applied to the development of follow-up valve technology and even lower the research and development costs. Its research results are more effective.

A lot of corporate valve products have obtained many national patents, but many patents are only practical patents, and their technical content is not high. Many patents have only been partially improved in structure, and have not substantially improved the invention. Some still have copying and plagiarism. Since many valve users have stayed in the use of traditional products for many years, many internal and external structures of products have not substantially improved and improved for many years.

Another example is the current China's valve actuator actuator control level is also poor. Domestic production of valve supporting actuators, its performance and control level is only foreign in the 1990s level, its poor sensitivity to the action, the overall level of automation control and reliability lags behind. With this, a series of control capabilities such as signal acquisition, signal comparison, signal amplification, and signal return lag behind those of developed countries.

In fact, in terms of technical level, the design of conventional valves and the application of materials, we do not have much difference compared with well-known foreign companies. There is no insurmountable gap in the manufacturing process. What is the difference? However, the actual situation is that in the serious word, there is such a product, originally a patent valve of a company in Germany, there are several different companies at the same time production, one is a foreign company, one is a Taiwan-funded enterprise, one Is a domestic company. The same product map, the actual valve produced is different. The first two companies have better internal quality and appearance than domestic ones. What is puzzling is that these companies are producing such products in China, and the castings are made from domestic factories, but the results are quite different. In a sense, our business philosophy, the pursuit of goals, and foreign-funded enterprises have a big gap, especially if there are indeed certain problems in the processing of rough products, it is also our reflection.

The practice of foreign companies is different from that of Chinese enterprises. The Chinese enterprises first engage in infrastructure construction, expand production plants and add production equipment. The plant also expands and expands, pursues large-scale and modern style, and only wants to expand the scale of production and ignores it. Due to the R&D and investment in new products, the product's stamina is seriously insufficient, and most of the production products are imitations, only ordinary low-grade products are produced, too much effort is put into market operations, and improper competition is used to engage in product marketing competition, thus lacking core competition. force. A lot of domestic companies engaged in research and development, the more is to refer to the design of other manufacturers, thus ignoring the importance of the original experimental data, so that the product developed only has a shape and no real soul.

As a whole industry system, there are also certain problems. Our R&D system is rather weak, but it is weak in innovation capability. Now some companies have a lot of branches and associates, some companies invest in research and development capabilities, and the construction of scientific and technological teams. In addition, there are also small investments in the establishment of research and development facilities. In fact, the investment in R&D is very large. Currently, the R&D team, R&D methods, R&D product testing measures, and type testing equipment of the entire industry are insufficient to support our valve industry. The implementation of scientific research and development and development of new products, not to mention the development of high-end products.

At the same time, we must soberly realize that as China has entered the WTO for several years, China’s economy has gradually integrated itself with the world economy, and strong foreign-funded enterprises have taken over the China’s valve market. These overseas legions have strong capital and high technology. Rich business strategy, invisible to the Chinese valve market poses a certain threat, but also our main competitors in the valve industry. At present, they are acquiring valve companies in China, attracting high-tech technical talents in the valve industry, using well-known brands, and seizing the high-end valve market in China. Some have invested in building factories in China, some have relocated their headquarters to China, and some have set up R&D centers in China.

2. Gaps in processing technology Abroad: In order to meet the radiation resistance requirements of the sealing materials for nuclear-grade valves, welding techniques such as the German KSB company have widely adopted special welding powders for cobalt-free welding by sintering powders and post-weld heat treatment. . The valve products are designed according to the requirements of the working conditions. The high-temperature and high-pressure gate valves adopt parallel parallel gate structures.

Welan Valve Company of France will preheat the welding process and equipment before welding. Automatic welding and post-weld treatment will be completed on the same equipment or on the same processing line. No matter pre-welding, welding or post-welding, the temperature can be controlled automatically. , To ensure the quality of welding, simplify the welding process, improve the welding efficiency, especially for relatively complex welds (such as automatic welding of straight and curved connections) to achieve automatic welding.

The domestic process behind the valve welding process, some also use the old welding method, the welder technology level is low, the welding material is also an ordinary material, can not reach the special valve design requirements. A lot of companies are busy with production and sales all day, and they rarely make improvements in the process. General production of ordinary valves and more, did not involve high-end valves, can think of the general level of technology.

The standard specification is backward and the parameters are not enough. The mastery of design and manufacturing standards such as ASMEBPVC and RCC-M, foreign manufacturers have systematically mastered these specifications and implemented them in design and manufacturing. Most of the domestic valve manufacturers are only partially mastered, do not have systematic and comprehensive in-depth studies, and have not fully grasped the functions, parameters, and requirements of various types of valves on the system. Foreign valve manufacturers are well aware of each location, function, parameters, requirements, and difficulties.

At present, the equipment capacity in the country is generally too small, and only forging blanks of 3〞 (DN100) or less can be produced. Therefore, the capacity of the equipment needs to be improved.

In the application of new technology for die forgings, since the intrinsic quality of forgings is better than that of steel castings, the high-end valves with medium and small calibers need to be 4-6 inches, and they need to use 3 tons or more forging hammers, 4000 tons of friction presses or 10,000 tons of hydraulic presses. High-end valve production requirements increase the capacity of forging equipment.Foreign company's production of valve materials are mainly high-temperature alloy steel F91, F22, while the high-pressure valve is mainly forged parts, forgings with more flexible design, can be seen at the job site To many free-forged multi-body welded structure valves, in this way, under the premise of reliable welding and non-destructive testing, the reliability and economy of the product are ensured, and die forging is applied to large batches of gate valves below 600Lb. Welding is carried out to ensure the compactness of the material of the blank. The valve has no defects such as porosity, looseness, etc. due to casting, and it can reduce the waste of free-forging material and greatly improve the economic efficiency.

Domestic: At present, most of the defective parts in the domestic industry are found in casting parts, and die forging is rarely used. Valves with a high pressure below 600 Lb can be described as phoenix phosphorus angles. Hengdian Machinery, Nanjing Huaning, Jianhu Dongfang Valve, Jinhu Jinshi Group, etc. have 1000-6000 tons of pressure die forging equipment, and can also forge DN100 valve bodies. With forgings, forging costs are higher, but the internal quality of the processing valve is absolutely first-rate. Recently, for the first time in the country, the HQW valve applied forging and welding technology to large-diameter high-temperature and high-pressure power station shut-off valves. The overall use of die-forging valves is suitable for high-temperature and high-pressure corrosive medium pipelines. The integral die forging valve not only retains the original welding flange valve. The appearance is beautiful, but also eliminates welding hidden dangers caused by welding, increases the strength of the valve body, eliminating the hidden dangers of corrosion resistance of the weld. The country says that on the level of forging steel, DN100 and DN600 reflect the gap between China's forging capacity and foreign presence.

With this domestic domestic cast steel technology and foreign countries have a big gap. If we use too many steel castings, there are also defects in the production technology of the blanks. The high-end valves have strict requirements on the chemical composition and uniformity of the molten steel. No slag inclusions or pores are allowed. The refining process is used abroad, and more AOD furnaces (argon oxygen decarburization refining) are used for smelting. The principle is to use oxygen and inert gas mixture gas instead of pure oxygen to blow molten steel, to change the thermodynamic properties of the decarburization process, and to reduce CO Partial pressure makes chromium excessively oxidized. Invasive blasting removes non-metallic inclusions and harmful dissolved gases such as oxygen, nitrogen, and hydrogen. The AOD process is an advanced technology for producing ultra-low carbon stainless steel and blunt high-quality alloy steel. The resulting steel castings have excellent mechanical and process properties (higher mechanical properties, improved impact toughness, etc.), and are mainly applicable to high-end valves. The requirements for molten steel. In addition, the resin sand molding process is used too much, which is inferior to the ester-hardened modified water glass sand molding process. The water glass sand process is basically an inorganic adhesive, and the gas generation is small, the sand type is concealed, and the castings are not prone to produce pores and cracks. , is the current high-end valve cast steel molding process of choice.

3, quality management and equipment gaps Many domestic counterparts in the production of backward equipment, has remained at the level of equipment in the 70-80 years, and some equipment has already passed the service life, is still running at full capacity. In order to make more money, some employers are reluctant to eliminate old equipment and purchase new equipment is far in the future. Can the quality of processed products be guaranteed? Some of them are limited to funds and they are gradually adding CNC and machining centers. However, the number of enterprises that form CNC machining has not been large in the industry so far, accounting for only about 20%.

Foreign: The quality of foreign valve products generally meets the requirements of API, JIS, BS and other standards, and the internal quality of casting blanks is high and the precision is high. It can be processed on the special machine without refurbishment, with beautiful appearance, clear cast characters, and good sealing performance. Fillers and gaskets have many specifications and can meet the requirements of different working conditions. Automatic control valve performance parameters are stable, fully guaranteed to not leak in use, accurate adjustment accuracy. The service life of universal valves can reach 1 to 2 maintenance periods or even longer.

For example, Bernard Electric Appliances Co., Ltd. sold 300 million yuan in 2005, exports accounted for 70% of sales, and established a global sales network. China's metallurgical and oil and gas pipelines and valves used a large number of the company's electrical products. In the field of nuclear power, their supply ranks second in the world. It is said that China's Qinshan Phase II, Daya Bay, Tianwan Nuclear Power Station, nuclear loading is also 80% of their goods. Their management is in place. The company's parts processing records are transferred along with the parts. The production site is neat and tidy. The two assembly lines are working in an orderly manner. Their screw processing adopts rolling method, high efficiency, and high surface finish of parts. The processed parts are cleaned in a timely manner, and the station equipment is properly applied. For example, a plastic bag is placed on each shaft, which is very simple but practical. It avoids scratches and scratches between parts. The coating method of the parts is similar to that of the domestic ones, but because the blank itself is smooth and the quality of the paint is excellent, the product after the painting has a very good appearance and quality.

Foreign companies have complete and advanced methods of quality control, advanced equipment for hot and cold testing, advanced coordinate measuring instruments, strict inspection of various testing equipment, and quality assurance. Each link is also in place, and each part is clear at a glance. Record very detailed and clear responsibility; Surface quality is good, including forging quality, surface grinding, weld quality, almost eliminates bump scratches; cleanliness is also high, including workshop civilized production and environmental hygiene, dust, rust, products All parts of the parts burr, flash edge cleaning, cleaning, as well as to clean, dry all parts of the assembly before they get a bit, leaving no trace. Employees are also dedicated and meticulous. The idea is higher prices, mainly for high-end valves.

Although the domestic valve industry started the work of adopting international standards, joint design, and joint development in the mid-1980s, and most of the products have adopted international standards and advanced foreign standards, due to the gaps in implementation, the current domestic valve product quality The level is still lower than the requirements of international standards. Mainly in: rough parts wall thickness is too bad; casting surface roughness quality is poor; casting size accuracy is poor; common valve leakage inside and outside the phenomenon is serious, and even some valves can not guarantee a reliable maintenance period of work; drive device varieties, specifications Incomplete, poor reliability, can not meet the needs of large-scale complete sets of equipment.

Domestic: In comparison, there are still many defects in quality management in China. First of all, the process is more or less neglected. Many companies clearly have a quality assurance system, but they can't do anything in practical work. It's up to you to do whatever you like; secondly, it's a sloppy thing in the assembly process. The paint process is also able to save the province, a lot of paint is not a standard, self-determined standards, the front itself did not deal with the workpiece, the surface hair, and some top coat a coating, covering the defects. In the debugging is not strictly controlled, it is no wonder that some valves appear to run, take, drip, leak phenomenon.

At the same time, a lot of domestic manufacturers have chaos in the processing of the valve, some of the ground is not smooth, large piles of ground on the ground, crushed the site; some are poor environmental awareness, can not effectively handle the dust after processing and dust, dust and surface parts, and some Paint anti-rust oil, rust marks; current domestic valve screw mostly use machine tool processing, concentricity, finish is poor, in fact, Zhejiang Zhiyuan valve company has specialized processing of this advanced technology valve, screw, and gradually in the industry Comprehensive promotion. In order to save costs, many factories in China even use paint to paint the valve, and some use ordinary paint. The surface is not coated with rust-proof oil. Only one item of paint is used for cutting corners. How can this processing process guarantee the appearance quality? Some of the valves are cheap, and they have a lot to do with material composition and process simplification.

Another example is that many domestic companies are behind in production equipment and have remained at the equipment level in the 70-80s. Some equipment has already passed the service life and is still running at full capacity. In order to make more money, some employers are reluctant to eliminate old equipment and purchase new equipment is far in the future. Can the quality of processed products be guaranteed? Some are also actively investing funds to gradually increase the number of CNC machine tools and machining centers. However, the number of enterprises that form CNC machining has not been large in the industry so far, accounting for only about 20%.

4. Disparity in process management In machining technology, most of the domestic valve manufacturing equipment is based on universal machine tools, the manufacturing precision of the products is low, and the level of manufacturing technology is also behind, which is also one of the reasons for the uneven quality of valve products.

Foreign: The characteristics of the production process of Italy's New Guinean company are: after receiving the order, the design and development center will be transformed to provide product design drawings, technical documents such as outsourced outsourcing details and machining procedures, etc., which will be transmitted to relevant departments through the internal network. The production department organizes production according to technical requirements and sales orders. After the blanks are brought into the factory, the warehouse personnel will send the blanks and other parts to the various processing and assembly sites according to the production plan. They are not all self-produced, and many are also purchased. However, almost all of their product components are completed on numerical control equipment with high machining accuracy and high processing efficiency. Employees can read the parts processing drawings and parts processing programs on the console of the CNC machining equipment. He only needs to press the workpieces to the CNC equipment according to the processing technology requirements, start the processing program, and can automatically complete the car, drilling, milling,é•— and other processing processes. When the processing program of a piece of equipment is started, another piece of equipment will be clamped. At the same time, the processing conditions of other equipment can be monitored on the equipment operation screen until the completion of the processing of the entire part is completed and sent to the assembly plant after passing the inspection. After completing the processing of each part, the staff brushed the part tracking card on the card reader nearby, and fed back the status and processing information of the part to related departments, so that the relevant departments can master the processing progress, count the workload and quality of the workers. track. And there are very advanced and perfect testing equipment, can carry out high-precision three-dimensional size detection, and dynamic balance test, high and low temperature test. Their warehouse management is very advanced. Three-dimensional computer management is implemented. The warehouse manager only needs to input production instructions and quantities into the computer. The system will automatically remove the required parts from the shelves, and then classify the packages and send them to the assembly shop.

Domestic: In this regard, the layout of domestic machinery processing equipment is mostly arranged according to the type of equipment, such as the arrangement of machining centers, horizontally placed in a row, vertical in a row, CNC machine tools in a row, this Arranging to consider the site tidy, without considering the inconvenience of labor, the efficiency is low, the cart before the horse. In the domestic industry, many valve companies are not professional, small and complete, products are mixed, processing valves are confusing, the layout of workshop processing equipment is unreasonable, parts are not stacked, space is occupied, and management is not advanced. At present, the domestic piece-rate working hour system is widely used, but it is also a lot of ills and the working hours are unreasonable. Therefore, due to the limitation of the enterprise process management level, the product technology level is low, the processing technology is lagging, and the raw materials are wasted. Many domestic brands of enterprise equipment have also been modernized, and generally use advanced equipment such as CNC machining centers with high processing precision and high automation. Digitalization and information technology are commonly used in processing equipment and quality control processes. Welding equipment is relatively complete, many types, and there are some special equipment developed based on product characteristics, practical, easy to operate, and high efficiency.

Some large state-owned enterprises in the country can currently produce parts for overseas valve companies. However, these companies have advanced computer data control processing centers and CNC machine tools, computer-aided design, three coordinate measuring equipment. And these devices are rarely used for the processing of domestic products. This also hindered the improvement of China's valve industry design capabilities. Therefore, the design capability of most domestic valve companies can only meet the domestic market.

In terms of test technology capabilities, the domestic valve industry is limited by capital investment, and only a few valve companies have specialized testing facilities, and the test analysis methods are still weak. The lack of critical high-end valve test research and test conditions, such as hot, dynamic, and cold and heat alternating test conditions, has constrained the testing of many products. If the main steam isolation valve simulates the fluid blocking performance test when the upstream and downstream pipelines are broken, and the displacement test of the safety valve of the regulator, etc., there is no test bench in the country to carry out the above test, and it is through these tests that it can be verified. The reliability of the valve. While advanced foreign companies rely on group development, they have strong capabilities and can invest in large-scale scientific research. Many companies have advanced research and development institutions and test equipment, such as high-temperature and high-pressure safety valve performance test equipment, regulating valve flow test equipment, etc. Companies such as Okano, Dreiser, Fisher, Sulzer, and Siemens all have enterprise R&D test bases. The strong R&D strength has enabled foreign manufacturers' products to continuously innovate and improve, monopolizing a market for high-end products.

Although China has been advocating the implementation of localization of key valves for nearly 10 years, the pace of localization is still accelerating. Currently, some key valves in the fields of nuclear power, thermal power, and petrochemicals have been domesticized. However, there are still gaps, and thermal power plants and petrochemical high-parameter control valves, pressure reducing valves and safety valves, nuclear power plant key valves, petrochemical, metallurgical equipment used high temperature and high pressure valves, metal sealing butterfly valves and metal sealing ball valve and a large number also rely on from Imported abroad, about 20% of the valve products need to be imported or matched with related equipment. The standard specification is backward and the parameters are not enough. With this large number of valves, electrical equipment relies on imports.

Due to the adoption of advanced foreign technology standards in the domestic valve manufacturing industry, the popularity of new materials, new technologies, and new processes has increased. As well as the convergence with foreign advanced technology standards, it appears that the existing national standards and industry standards are lagging behind. Many of the national standards now implemented by the valve manufacturing industry were formulated in 1989 and could not keep up with the needs of market development. The lag in the formulation and revision of standards also restricts the development of the industry. Because some users and owners lack understanding of the performance of domestic valve manufacturers and existing valve products, domestic companies do not have the performance to purchase localized products that have reached the international level. This also affects the rapid development of domestic enterprises and reduces the gap with foreign countries. one of the reasons.

Second, efforts to improve and promote the healthy development of the valve industry is obvious, there are gaps and existing problems are not terrible, as long as we adjust the development of ideas, enhance development confidence, strengthen corporate management, promote technological progress, attention to technological innovation and core technology research and development, Improve the company's core competitiveness. In the near future, China's valve backbone enterprises will surely be able to catch up with and surpass foreign similar companies, contribute to the nationalization of major national technical equipment, occupy a certain share in the world valve market competition, and become a strong country in the world of valve manufacturing.

In view of the above-mentioned problems and the gap with foreign valves in the same industry, our valve industry should seriously consider, in order to improve some problems in our development, to overcome the problem of non-harmonious development, to identify the development of the meeting point, and jointly promote Valve industry rejuvenation and improvement. To this end, it is suggested that valve companies should turn challenges into opportunities, identify their own positioning, and strive to open up markets at home and abroad to resolve the adverse effects of the crisis. The most critical thing for China's valve companies is to further improve product quality and technological content. Only with a solid foundation and unremitting exploration and innovation, China's valve brand can be renowned overseas.

First, we must have a sense of innovation. With a sense of innovation, companies will be motivated to work hard and seize opportunities. Many companies in the valve industry in Wenzhou and other regions also adopt the home-shopping model, and urgently need to establish modern management concepts, including market awareness, service awareness, competition awareness, and crisis awareness. In the development of the market, including long-term planning and countermeasures, including the establishment of a promotional platform, the selection and delivery of promotional media, the search for customers, the establishment of new customer relationships, the communication and exchange of business, and the production of new orders. The valve industry must also attach great importance to technological development and innovation, and strive to form a development mechanism for technological development and innovation.

The core of enterprise innovation is “technological innovation”. Whether a company has vitality or not depends on whether the products produced by the enterprise have vitality or high-tech or advanced products, which will bring development and benefits to the enterprise, and the products that are outdated will be eliminated. The business brings nothing but bankruptcy and bankruptcy. As we mentioned above, the majority of SMEs at present do not want to take independent innovations and brains to develop new products. They are always greedy and convenient. You learn from me, I learn from you, I do not know the vitality of the product. , Market share, etc., in one move, hit the market, resulting in disorderly market competition and disorderly market economic order. At present, efforts should be made to reverse the phenomenon of "inadequacy of innovation and imitating surpluses."

At present, valve companies must persist in innovation, structurally adjust products, transform traditional products, and advance into high-end valves. Companies that require a scale must take the lead in this effort and strive to gradually increase the domestic valve industry's level and competitiveness by purchasing over a third of the current domestic valve products that are purchased overseas. Small businesses, on the other hand, take specialization. Production, do a factory one product, do fine and stronger, make efforts to improve management, improve process tooling, improve product quality and grade and competitiveness. Many successful companies in the world grow from small to large, weak to strong, and develop into large companies with strong vitality. They are all achieved through continuous innovation, so the strength of the company’s innovation ability will ultimately be determined. Corporate competitiveness and business efficiency and effectiveness. In order to fully enhance the valve industry quality and image.

Second, efforts are made to open up the domestic and foreign markets: The development of domestic and foreign markets is a process of continuous self-improvement and development. It is in fact a process of development and growth. At this stage, relevant enterprises should adopt the "two legs" strategy based on actual conditions and pay attention to the development of both domestic and international markets. Adopting this market development strategy can reduce business risks to a certain extent, enable enterprises to play steadily, gradually and gradually expand the scope of the target market, which will greatly benefit enterprises.

Third, strengthen cost control to resolve competitive pressures. The process of cost control is the process of calculating, adjusting, and supervising various costs incurred by enterprises in the course of production and operation using the principles of system engineering. It is also a process of discovering weaknesses, tapping internal potentials, and finding all possible ways to reduce costs. . For the domestic manufacturing enterprises, it is necessary to scientifically organize the implementation of cost control, promote the improvement of business management, change the operating mechanism, improve the overall quality of the company, and enable the company to continue to develop and grow under the fierce market competition environment. Adjust the structure of production capacity, expand the development of connotation.

Fourth, speed up the effective integration, transformation and development of resources. After a healthy development in the first 10 years, it has laid a foundation for further development, and thus contains a favorable balance of the valve industry to achieve structural adjustment. With the deepening of the market economy, China's valve industry has encountered many problems such as “low, small, scattered” and so on, and the industry has encountered difficulties. Some SMEs that rely on low-price competition and have no obvious brand effect are struggling and are close to the edge of bankruptcy. There is no way out of the world. In recent years, valve companies have realized that they must overcome the current industrial difficulties and must accelerate the pace of joint restructuring. Some forerunners in the Wenzhou valve industry have boldly chosen the road of “joint reorganization and renewed development” and have achieved success at first, in order to realize the purpose of complementing resources and common development, enhance the competitiveness of enterprises, expand the living space, and move forward. The new "1+N" optimization combination creates a new path for innovation.

Fifth, update the concept, abandon the conservative concept of “small wealth and safety”, learn from Wenzhou people's courage to take risk and be creative, and do a good job in upgrading the technology of enterprises and upgrade the overall equipment level of the company. And increase investment. Increase the investment in research and development of new products, especially increase the investment in basic research of valve products, make every effort to improve the technical content and added value of valve products, and create necessary conditions for the maximization of profits of enterprises. Also change the system. At present, all valve companies are private joint-stock enterprises, with advanced management concepts and flexible management methods. Therefore, it is imperative to change the system, realize the corporate shareholding system and the professionalization of management personnel as soon as possible, change employees to change shareholders, change me to do what I want, further increase the enthusiasm of employees and management personnel, and realize the leap-forward development of enterprises.

Sixth Accelerate the Training of Talents and Promote Industry Progress: At present, it is the age of knowledge economy or strategic competition. In the final analysis, the competition of enterprises is the competition of talents. People-oriented, talents are of unprecedented importance. At present, China's valve companies are relatively short of technical and managerial talents. The overall quality of employees is also low. Especially in the development and rise of western industries, foreign talents are gradually reduced. Therefore, in the valve industry and other industrial enterprises, high, medium and The talent crisis of low-level and general workers is difficult to attract talents. It has attracted the attention of CEOs of major valve companies. They are seriously thinking about how to develop talents. From now on, enterprises must further tap talent resources and potential to develop human resources, make efforts to strengthen personnel training, respect talents, attract talents, make good use of talents, adhere to the people-centered approach, and use various methods and approaches to stimulate mental and manual labor. The enthusiasm, wisdom and creativity of the person contribute to the development of the enterprise and the progress of the industry.
