Description

technical field [0001] The invention relates to a check valve used on an air compressor, in particular to a check valve for an air compressor. Background technique [0002] In the existing air compressor check valve, the sealing ring is directly facing the impact of compressed air. Affected by factors such as temperature, pressure and impact frequency during use, the sealing ring will fall off and be damaged, so that the air compressor Therefore, the one-way valve is scrapped, so the existing air compressor one-way valve has the defect of short service life. Contents of the invention [0003] The invention provides an air compressor check valve capable of prolonging service life. [0004] The present invention adopts following technical scheme: [0005] An air compressor check valve, comprising a valve body, an air inlet chamber and an air outlet chamber are arranged in the valve body, an air inlet is arranged in the air inlet chamber, an air outlet is arranged in the ai...
