Exhaust valve plate and compressor

Abstract

The invention provides an exhaust valve plate and a compressor. The exhaust valve plate comprises a root section, a waist section and a head section. The head section is opposite to an exhaust port. The root section, the waist section and the head section are connected into a whole, and the waist section is located between the root section and the head section. The width of the joint of the waistsection and the root section is b1, the width of the joint of the waist section and the head section is b0, and the width of the waist section is set to be b1 which is larger than b0. According to theexhaust valve plate and the compressor, the rigidity of the valve plate is adjusted by adjusting the width of the valve plate on the premise that the equal thickness of the valve plate is guaranteed,the reliability of the valve plate is improved, the in-applicability problem of variable-rigidity schemes such as variable modulus, variable thickness and sliding block movement is solved, the performance of the compressor cannot be reduced, and the noise level is decreased. Compared with the variable-rigidity schemes such as variable modulus, variable thickness and sliding block movement, machining is easy to achieve, and the effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an exhaust valve plate and a compressor. Background technique [0002] The compressor is known as the heart of the air conditioner, and it realizes the heat exchange of the air conditioning system by compressing the refrigerant. As the core component of the compressor, the exhaust valve plate controls the discharge of gas when the refrigerant is compressed to a certain pressure in the cylinder. When exhausting, the valve plate opens quickly to a certain lift, causing the valve plate to hit the baffle violently; when the exhaust is over, the valve plate will quickly close due to its own stiffness and slap the valve seat violently, and the valve plate slaps the baffle repeatedly And the valve plate often causes the fracture of the valve plate. The fracture of the valve plate is mainly manifested in two forms: the bending fracture of the root of the valve plate and the impact ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is mainly to overcome the defect that the compressor exhaust valve plate in the prior art is prone to breakage, and the stiffness is changed by changing the thickness or elastic modulus, which will reduce the performance of the compressor. Thereby providing an exhaust valve plate and compressor
