Description

Technical Field

[0002] In the context of the rapid development of current valve technology, as a key component for fluid control, the performance and lifespan of the valve core directly affect the stable operation of the entire valve.

[0003] In the prior art, valves use a combination of ceramic valve cores and ceramic valve seats. However, ceramics are prone to cracking and breaking, especially when the valve core is stressed, which greatly limits the scope of use of the valve. Valves using a combination of metal valve cores and ceramic valve seats solve the above problems. However, under the action of powder impact, the service life of the metal valve core is extremely short. Especially when the valve is adjusted and controlled, the powder impacts the metal valve core for a long time, and the service life of the valve core is even shorter, unable to meet the production control requirements.
