Exhaust valve plate applied to compressor

Abstract

The invention relates to an exhaust valve plate for a compressor. A main body of the exhaust valve plate is of a three-layer composite structure. The three-layer composite structure comprises a firstmetal valve plate layer, a damping layer and a second metal valve plate layer. The damping layer is arranged between the first metal valve plate layer and the second metal valve plate layer in a clamped mode. Compared with metal exhaust valve plates in the prior art, the exhaust valve plate for the compressor adopts the composite structure that the damping layer is clamped between the two metal valve plate layers; an inventor finds that when the metal valve plate layers and the damping layer are combined by adopting a specific thickness and physical parameters, the composite structure can combine the advantages of both metal valve plates and a damping material, the stiffness and flatness required for the exhaust valve plate are reserved, the sealing performance in the compression process is ensured, the frequency response performance of the whole exhaust valve plate can also be improved, a frequency response curve is smoother, and especially vibration and noise when the exhaust valve plate is rebound to a valve seat can be reduced.

Description

technical field [0001] The invention relates to an exhaust valve plate applied to a compressor. Background technique [0002] The compressor discharge valve plate is a key component in the compressor. Its main function is to provide a closed space for the compression process of the compressor. When the pressure of the discharge chamber reaches the discharge pressure, the discharge valve plate is subjected to pressure And pop open, discharge the compressed refrigerant. Therefore, generally speaking, the exhaust valve plate is required to have a certain rigidity, so as to achieve the effect of restricting the closed space. [0003] The current exhaust valves are generally made of metal materials. However, the metal exhaust valves have obvious frequency response characteristics and high vibration noise; moreover, in the actual operation of the compressor, the exhaust valves are prone to fatigue and Deformation occurs which leads to failure of the valve plate, which affects th...
