Description

Technical Field

[0002] The compressor is a general-purpose machine used to increase the pressure of various gases. The air valve is an important component in the compressor used to control the timely intake and discharge of gas into and out of the cylinder. During long-term use, the performance of the air valve directly affects the exhaust volume, power consumption and operational reliability of the compressor. For example, as shown in an air compressor intake valve with Chinese patent application number CN202022147325.6, the bottom of the intake valve body is fixedly connected to a connecting pipe, a fixed sleeve is fixedly sleeved on the outside of the concentric axis of the connecting pipe, a telescopic sleeve is movably connected to the outer wall of the fixed sleeve, a rubber plug is fixedly connected to the bottom end of the fixed sleeve, grooves are provided on both sides of the telescopic sleeve, a telescopic spring is fixedly connected to the inner wall of one side of the groove, and a positioning pin is fixedly connected to the end of one side of the telescopic spring.

This will cause the air passing through the exhaust valve to impact the intake valve plate, which will cause the intake valve to detach in the long term, and then cause air leakage.
