Pressure self-adaptive valve plate component

Abstract

The invention discloses a pressure self-adaptive valve plate component, and belongs to the technical field of compressors. The pressure self-adaptive valve plate component comprises a valve plate and valve blocks. The valve plate is provided with an air suction hole, an air exhaust hole and a pressure release hole. The valve blocks comprise the air suction valve block arranged on the front side of the valve plate and the air exhaust valve block arranged on the rear side of the valve plate. The air suction valve block is provided with a flexible air suction tongue piece located on the front side of the air suction hole, and the air suction valve block avoids the air exhaust hole and the pressure release hole. The air exhaust valve block is provided with a flexible air exhaust tongue piece located on the rear side of the air exhaust hole, and the air exhaust valve block avoids an air inlet and the pressure release hole. A pressure release valve is arranged in the pressure release hole. The pressure release valve is additionally arranged on the valve plate, it is ensured that the pressure release valve is opened when air exhaust pressure is tool high due to the fact that a system is abnormal under the condition that the thickness of the air suction valve block is not increased, the effect of air exhaust pressure on the air suction valve block is reduced, and it is ensured that stress on the tongue piece of the air suction valve block is not too large so as not to damage the tongue piece. Meanwhile, by means of the structural scheme, the structure of the original air suction valve block is not changed, the air output efficiency of a compressor can be ensured, and the performance of the compressor can be ensured.

Description

technical field [0001] The invention is used in the technical field of compressors, and particularly relates to a pressure adaptive valve plate component. Background technique [0002] The working process of the existing compressor mainly includes a suction process and an exhaust process. During the suction process of the compressor, the suction pressure is low pressure, and the thrust of the airflow is small. Large, the suction valve is closed, and the exhaust valve is opened. The suction valve plate and the exhaust valve plate are an important elastic element in the reciprocating compressor. If the valve plate is damaged, the compressor will lose its function of conveying gas and can only be scrapped. The safety design of the air valve can meet the life requirements under normal conditions, but when the refrigerator system is abnormal, such as the wrong filling volume causes the balance pressure to be too high, the liquid enters the cylinder hole and causes the liquid ha...

Problems solved by technology

[0004] However, increasing the thickness of the suction valve will lead to a decrease in the deformation of the valve. In the process of inhalation, the suction pressure is constant, the thrust of the airflow is basically stable, the opening degree of the suction valve is not large enough, and the gas flow area is reduced. Compressor gas transmission efficiency is low
