Description

Combined type high-speed air inlet and outlet valve

Technical Field

The utility model relates to a pneumatic valve equipment technical field specifically is a combined type high speed inlet and outlet valve.

Background

The gas valve is a component of the compressor that controls the flow of gas into and out of the cylinder. Mainly comprises a valve seat, a valve plate, a spring and a lift limiter. The rising height or the closing height between the valve plate and the valve seat determines the size and the sealing of the gas channel. The spring is mainly used for pushing the valve plate to close and can also reduce the impact of the valve plate on the lift limiter when the valve plate is opened. The lift limiter can limit the lift of the valve plate and can seat the spring; the opening and closing of the valve plate of the air valve are controlled by the pressure difference of air inside and outside the air cylinder and the spring force, and other driving mechanisms are not needed, so the valve is called an automatic valve.

The combined high-speed air inlet and outlet valve adopts a top-mounted structure, connecting bolts of the valve body are reduced under the conditions of high pressure and large caliber, the reliability of the valve is enhanced, and the influence of the dead weight of the system on the normal work of the valve can be overcome; when a large amount of intake air enters from the air inlet and is discharged through the exhaust sealing rubber gasket, the discharge capacity is always blocked by the exhaust sealing rubber gasket. When water comes later, the water pushes the floating ball to float, and the bottom plate surface of the guide rod is lifted to the position where the exhaust sealing rubber gasket is matched by virtue of the pushing force of the floating ball, so that the sealing effect is achieved, but abnormal sound can occur if the water flow (emergency) is greater than the water pressure of 1.6 MPa. Noise is increased and the service life of the valve is reduced. In order to solve the above problems, a composite high-speed intake and exhaust valve is provided.
