?We understand that the rubber O-ring
??Advantages The rubber O-rings are: (1) high-pressure rubber O-ring both high temperature resistance, abrasion resistance and have mechanical seals for pumps, able to work under harsh conditions; (2) high-pressure rubber O-ring to have a very strong corrosion resistance, habits can be a variety of media; (3) high-pressure rubber O-ring anti-extrusion ability, long life, can be more useful to carry forward the seal.
??From their own mass of the rubber O-ring to carefully check the appearance of scales Try again, the quality of clearance of rubber O-ring on the life of the president; start from the raw material of the seal, if the temperature in the work, you can choose the type of rubber O ring material is only suitable for low-temperature condition information that is not necessarily a long service life.
??Leaks rubber O-rings before a called internal leakage, which is commonly known as Guan lax, it will affect the ability of the valve cut off media. For the cut valve, the internal leakage is not allowed. After two seal leakage is called the leak, that media leaks from the valve to the outside of the valve, leakage would cause material losses, environmental pollution, can also cause serious accidents for flammable, toxic or radioactive medium , leakage is allowed, and therefore, the valve must have a reliable sealing performance.
