Problems solved by technology

This is because under the same cross-sectional area, the edge length of the reed 110 with a circular (or oval) reed end 130 is relatively small, so that the length of the gap 140 between the reed 110 and the valve plate 100 is relatively small, Thereby reducing the suction efficiency of the suction valve plate 001; at the same time, both sides of the reed 110 of the suction valve plate 001 have contracted parts 150 contracted inwardly, and the contracted parts 150 on both sides of the reed end 130 and the reed 110 The convex-concave combination makes the stress concentrate on the end 130 of the reed, which reduces the structural strength of the reed 110, and the vent hole 120 provided on the side of the reed 110 will also make one side of the reed 110 bear more force than the other side, so that the reed 110 Unbalanced force produces a large torque, which reduces its service life

Abstract

The invention relates to an air suction valve and a compressor, belonging to the field of refrigerating compressor accessories. The air suction valve comprises a valve plate, wherein a first reed is arranged on the valve plate, a U-shaped first ventilation clearance is formed between the first reed and the valve plate, a second reed is arranged on the first reed, a second ventilation clearance is formed between the second reed and the first reed, and a ventilation hole is formed in the second reed. The air suction valve has the advantages that the structure strength is large, the air suction efficiency is high, and the service life is long. The invention further provides a compressor using the air suction valve, and the compressor is high in air suction efficiency and low in fault rate.

Description

technical field [0001] The invention relates to the field of refrigeration compressor accessories, in particular to a suction valve plate and a compressor. Background technique [0002] The suction valve is an important part of the compressor. It is mainly used to control the gas flow into and out of the compressor. The performance of the suction valve directly affects the suction efficiency of the compressor. The suction valve plate is generally composed of a valve plate, a reed on the valve plate and a vent hole. During the suction and exhaust process of the compressor, a pressure difference is generated on both sides of the suction valve plate, and the compressed gas passes through the vent hole. Pass the valve plate and push the reed to produce deformation, so that more compressed gas will pass through the suction valve plate from the gap between the reed and the valve plate, so the size of the gap between the reed and the valve plate affects the suction of the compresso...
