Compressor air valve is an important part of the compressor used to control the suction and discharge of gas in a timely manner.

Compressor valve Air vale is an important part of the compressor used to control the timely intake and discharge of gas from the cylinder. The air valves on the piston compressor are all automatic valves, that is, the opening and closing of the air valve is not achieved by a compulsory mechanism but by the pressure difference (the pressure difference between the gas pressure in the cylinder and the valve cavity) on both sides of the valve disc. Commonly used automatic valves include ring valves, mesh valves, strip valves, reed valves, disc valves, and DC valves. Each type of valve is divided into an intake valve and an exhaust valve. All gas valves are mainly composed of four parts: [1] the valve seat, which has a gas passage that can be covered by the valve disc, locks the intake (or exhaust) passage with the valve disc, and bears the pressure difference between the inside and outside of the cylinder;} 2J valve Sheet, which alternately opens and closes the valve seat channel; {3) a spring, which pushes the valve sheet to fall to the valve seat when closed, and suppresses the valve sheet from hitting the lift limiter (}) when it is opened. And DC valve and other structures, the valve itself has elasticity and functions as a spring, so the two are combined into one); (4) a lift limiter, which limits the lift of the valve, and is often used as a part of the seat spring. The performance of the air valve directly affects the displacement, power consumption, and reliability of the compressor. Therefore, the requirements are as follows: (1) The resistance loss of the gas flowing through the valve should be small, and the total relative power loss of the exhaust gas is limited. In the range of 4% -9 3'0; (2y long life (reliable

(Good performance and durability), the most vulnerable parts of the valve are the valve disc and spring, requiring the valve disc or spring under repeated impacts, so as not to wear and damage over dry land. The life expectancy is up to f) f) flf) h; (s) the valve does not leak when the valve is opened and closed;}) 7? The gap formed by ^{[?] Is} small; (5) the noise is small;
