Exhaust valve plate for compressor, exhaust valve module and compressor

Abstract

The invention discloses an exhaust valve plate for a compressor, an exhaust valve module and a compressor. The exhaust valve plate for the compressor is substantially strip-shaped with a length as S; S is smaller than 25 mm and bigger than 15 mm; at least one part of the exhaust valve plate is bent to one side of an exhaust valve port so as to form a height difference h1 between one end and the other end of the exhaust valve plate; and h1 is smaller than 0.5 mm and bigger than 0.03 mm. According to the exhaust valve plate for the compressor, one part of the exhaust valve plate is bent to one side of the exhaust valve port so as to warp the end part; the warping height of the end part of the exhaust valve plate is controlled to form lower pressure between the exhaust valve plate and the exhaust valve port; meanwhile, the compensation effect on the machining error of the exhaust valve port and the like can be achieved; the exhaust valve plate can be tightly bonded on the exhaust valve port to reduce the leakage; and the warping structure of one end of the exhaust valve plate can enable the exhaust valve plate to obtain higher resilience force, so that the exhaust time is shortened, and the exhaust efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of compressor manufacturing, and more particularly, relates to a discharge valve plate for a compressor, a discharge valve assembly and a compressor. Background technique [0002] Reciprocating refrigeration compressors are widely used as core components in small refrigeration equipment such as refrigerators and freezers. The exhaust valve assembly is one of the core components of the reciprocating refrigeration compressor. The exhaust valve assembly controls the exhaust of the compressor. Process and sealing process, the structure of the exhaust valve plate plays a vital role in the airtightness of the exhaust process, and will have a direct impact on the refrigeration performance of the compressor. [0003] At present, the exhaust function of the exhaust valve assembly is usually achieved through the cooperation of the exhaust valve plate and the sealing surface of the exhaust valve port, and the exhaust a...

AI Technical Summary

Problems solved by technology

However, since the design of the exhaust valve plate is mostly a flat structure, errors often occur during the manufacturing process, causing the exhaust valve plate to warp by about 0.03 mm. If the front and back sides are not distinguished before assembly, when the exhaust valve plate is When the tilting direction of the valve plate is installed away from the exhaust valve port, it will cause poor sealing between the exhaust valve plate and the exhaust valve port, resulting in excessive leakage of the exhaust valve assembly

In addition, the exhaust valve plate with a planar structure rebounds slowly at the end of the exhaust stage, which will also affect the refrigeration performance of the reciprocating refrigeration compressor.
