Introduction: Safety valves play a safety role in the system. When the system pressure exceeds the specified value, the safety valve opens, and part of the gas/fluid in the system is discharged into the atmosphere/outside of the pipeline, so that the system pressure does not exceed the allowable value, so as to ensure that the system does not cause accidents due to high pressure.

POM Polyoxymethylene Plastic Products
Polyoxymethylene (POM) is a highly versatile engineering thermoplastic that is widely used in the manufacturing of various products. POM is known for its excellent mechanical properties, high stiffness, low friction, and excellent dimensional stability. These properties make POM an ideal material for the production of precision parts that require high accuracy and tight tolerances.

In the normal use of the safety valve and verification, due to improper design, manufacture or use will cause various failures. These failures are not eliminated in time, which will affect the effectiveness and service life of the safety valve. In severe cases, it will also endanger the safety of users.
After the relief valve exhaust pressure continues to rise, the main reasons and solutions:
1. The selected safety valve displacement is less than the safety discharge of the equipment, and the appropriate safety valve should be selected again;
2. The valve rod centerline is not correct or the spring is rusted, so that the valve flap cannot be opened to the proper height. The valve stem should be reassembled or the spring replaced;
3. Exhaust pipes should not be cut enough and exhaust pipes that meet the safety discharge area should be used.
POM plastic products are widely used in various industries, including automotive, electrical, medical, and consumer goods. The automotive industry uses POM plastic products in the manufacturing of fuel systems, door handles, and gears. The electrical industry uses POM plastic products in the production of connectors, switches, and housings. The medical industry uses POM plastic products in the manufacturing of surgical instruments and medical devices. The consumer goods industry uses POM plastic products in the production of toys, kitchen utensils, and sports equipment.
POM plastic products are available in different grades, including homopolymer and copolymer grades. Homopolymer POM is a high-performance material that is known for its excellent mechanical properties and high stiffness. Copolymer POM is a lower-cost material that is more flexible and has better impact resistance than homopolymer POM.
