Aluminum Plastic Pipe Fittings Support Customization

The gas valve is a component of the compressor used to control the flow of gas into and out of the cylinder. It is mainly composed of valve seat, valve plate, spring and lift limiter. The lifting height or closure between the valve plate and the valve seat determines the size and tightness of the gas channel. The spring is mainly used to push the valve plate to close, and can also reduce the impact between the valve plate and the lift limiter when it is opened. The lift limiter can limit the lift of the valve plate and can support the spring; The opening and closing of the air valve plate is controlled by the pressure difference between the inner and outer air cylinders and the spring force, and no other driving mechanism is required, so it is called the automatic valve.
From the working principle of the air valve, the working performance of the air valve will directly affect the work of the compressor cylinder. Therefore, the following requirements are made for the air valve:
(1) Low resistance loss
The resistance loss of air valve is related to the valve clearance velocity and spring force of air flow. The higher the gas velocity, the greater the energy loss; If the spring force is too large, the resistance loss is also large, and its size is determined according to the reasonable rule of valve movement.
(2) The gas valve shall be closed timely and quickly
No air leakage when closing, to improve the efficiency of the machine and extend the service life.
(3) Long service life and reliable operation.
The main factor limiting the service life of the air valve is the quality of the valve plate and spring. Generally, the service life of the compressor with long-term continuous operation is expected to be more than 8000 hours; The requirements for mobile, short-term or intermittent compressors can be slightly lower.
(4) The clearance volume is small
(5) Low noise
In addition, the valve shall be easy to assemble, install, maintain and process.
