Novel compressor self-limiting exhaust valve plate, exhaust valve plate assembly and compressor

Abstract

The invention provides a novel compressor self-limiting exhaust valve plate, an exhaust valve plate assembly and a compressor, and relates to the technical field of compressors. The novel compressor self-limiting exhaust valve plate comprises a valve plate body, wherein a mounting hole is formed in one end of the valve plate body in the thickness direction of the valve plate body; and a groove transversely penetrating through the valve plate body is formed in the surface of the valve plate body in the thickness direction of the valve plate body. According to the novel compressor self-limitingexhaust valve plate, the exhaust valve plate assembly and the compressor, the mounting hole is formed in one end of the valve plate body to mount and fix the valve plate body to a valve seat, meanwhile, the groove transversely penetrating through the valve plate body is formed in the surface of the valve plate body in the thickness direction of the valve plate body, when the compressor exhausts, the valve plate body is bent due to impact of gas, at the moment, an opening of the groove can be gradually decreased along with increasing of the bending angle of the valve plate body, when the valveplate body is bent to a certain angle, the groove is completely closed, the valve plate body can be prevented from being continuously bent, thus automatic limiting in the bending process of the valveplate body is achieved, thus a baffle can be removed, noise caused by reciprocating impact of the valve plate body and the baffle and fatigue fracture of the valve plate body are eliminated, and meanwhile the number of parts of the exhaust valve plate assembly can be decreased.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a novel compressor self-limiting exhaust valve plate, an exhaust valve plate assembly, and a compressor. Background technique [0002] The exhaust valve assembly is an important internal part of the compressor and is widely used in various compressors. Its reliability is very important. At the same time, the flapping of the traditional valve and baffle is one of the main sources of compressor noise . [0003] The traditional exhaust valve assembly is mainly composed of a valve plate, a baffle, a valve seat and rivets. The valve plate is a flexible sheet structure. During the exhaust stage, the valve plate is opened, and its lift is limited by the baffle; Finally, through the stiffness of the valve plate itself, the deformation is restored. When the compressor exhausts, the high-pressure gas pushes the valve plate to open through the exhaust hole, resulting in a high-speed i...

AI Technical Summary

Problems solved by technology

When the compressor exhausts, the high-pressure gas pushes the valve plate to open through the exhaust hole, resulting in a high-speed impact between the valve plate and the baffle plate. The reciprocating impact of the valve plate and the baffle plate often leads to fatigue fracture of the exhaust valve plate and compressor noise. intensification of

[0004] In addition, with the development trend of miniaturization of compressor structure and high-speed operation frequency, high-speed compressors have higher and higher requirements for exhaust valve components. Due to the high operating frequency of the compressor, the traditional exhaust valve plate reciprocates with the baffle If the degree is intensified, the risk of valve plate fracture is likely to occur, which will affect the reliability of the compressor. At the same time, the high-frequency flapping baffle will increase the noise of the compressor. It is an urgent need to improve the design of the current high-speed compressor.
