Air inlet and exhaust valve of compressor

Abstract

The invention discloses an air inlet and exhaust valve of a compressor, which comprises a valve body, an air valve plate, a spring, a spring seat and an air inlet and exhaust connector, wherein the valve body is arranged on the valve seat; the spring applies a pretightening force during installation to press the air valve plate onto the valve seat tightly; seal is formed between the air valve plate and the valve seat to separate the channels positioned above and below the air valve plate; the air valve plate is made of an impact-resistance nonmetal material and is provided with a guide structure preventing the sidewise inclination of the air valve plate during reciprocal motion of the air valve plate; the valve body is provided with a structure matched with the guide structure; and the center of the air valve plate is provided with a central hole for reducing the weight of the air valve plate and increasing circulation area at the same time. The air valve has the advantages of compact arrangement, simple structure, small resistance to air flow, low vibration noise, high reliability and the like and is particularly suitable for use in medium and small flow reciprocating piston type compressors.

Description

technical field [0001] The present invention relates to compressors, especially compressor inlet and outlet valves. Background technique [0002] The intake and exhaust valves are one of the key equipment on the piston compressor, and the quality of its design has an important impact on the efficiency, vibration, noise and reliability of the compressor. Traditional compressor inlet and exhaust valves can be divided into valve plate (plate) type and "spring + valve plate" type according to the sealing requirements. The former combines the spring and valve plate into one, that is, the spring plate type, which is mostly used for compression Air-conditioning compressors and other fields where the ratio is not very high and the sealing requirements are not very high; the latter has a good sealing effect and is widely used in occasions where the pressure ratio is higher and the sealing effect is strict. It generally includes valve body, valve seat, The main parts such as air valv...
