Valve bank structure for refrigeration compressor

Abstract

The invention discloses a valve bank structure for a refrigeration compressor, which comprises a valve plate spacer, an air suction valve sheet, a valve plate, an air exhaust valve sheet, a limiting sealing part, a cylinder cover and a fixing part, wherein the limiting sealing part is made of an elastic deformation material, and a limiting bump is arranged on the limiting sealing part. The functions and the quality of the valve bank provided by the invention are not reduced, the structures of parts are greatly simplified, the quantity of the parts is greatly reduced, the size of the valve bank is also slightly reduced, and the manufacturing cost is obviously reduced.

Description

technical field [0001] The invention relates to a valve group structure applied to a refrigeration compressor. Background technique [0002] Refrigeration compressors generally adopt a valve group structure, whose function is to inhale low-pressure gas at room temperature and discharge high-temperature high-pressure gas. like figure 1 As shown, the valve group structure of the existing refrigeration compressor includes valve plate gasket 2, suction valve plate 3, valve plate 4, exhaust valve plate 5, exhaust valve limiter 6, cylinder head gasket 7, cylinder Parts such as cover 8, screw 9. like figure 2 and image 3 As shown, the exhaust valve limiter 6 is generally made of metal material, and its function is to limit the lift of the exhaust valve plate 5; the valve plate gasket 2 and the cylinder head gasket 7 are generally made of rubber, paper pad and other sealing materials, and its function is to limit the lift of the exhaust valve plate 5; The function is to preve...

AI Technical Summary

Problems solved by technology
