Exhaust valve plate for compressor and compressor having the same

Abstract

The invention discloses a discharge valve plate for a compressor and the compressor provided with the discharge valve plate. The compressor comprises an exhaust vent and a bearing, the discharge vavle plate comprises N connecting pieces that are connected sequentially, the first connecting piece is suitable for covering the exhaust vent, the Nth connecting piece is fixed on a bearing, the elasticity modulus of the ith connecting piece is Ei, and the elasticity modulus Ei meets the following conditions in the direction from the first connecting piece to the Nth connecting piece: E1<E2<......<En-1<En, wherein N is an integer larger than or equal to 2. According to the discharge valve plate provided by the invention, the requirement of low rigidity of the discharge valve plate at the beginning of exhausting is met, the discharge valve plate is easy to open, the requirement of high initial speed of closing the discharge valve plate is also met, the discharge valve plate is rapidly closed without delay, meanwhile, the end speed of closing the discharge valve plate decreases gradually, the impact of the discharge valve plate on the exhaust vent is reduced, the fatigue life of the discharge valve plate is long, and the reliability of the discharge valve plate is high.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a discharge valve plate for a compressor and a compressor with the same. Background technique [0002] The energy efficiency of the compressor is one of the important factors affecting the energy efficiency of the air conditioner, and the compressor exhaust structure is one of the important links in the optimization of the energy efficiency of the compressor. The design of the exhaust valve directly affects the smoothness of the exhaust. [0003] At the end of compressor exhaust, theoretically, the faster the exhaust valve closes, the smaller the impact of high-pressure air flow backflow, and the higher the energy efficiency of the compressor. The premise of this expectation is that the closing speed of the exhaust valve should be large, but the exhaust valve When the valve is about to be completely closed, the greater the speed, the greater the impact force of the valve plate on the b...

[0003] At the end of compressor exhaust, theoretically, the faster the exhaust valve closes, the less the impact of high-pressure air flow backflow, and the higher the energy efficiency of the compressor. The premise of this expectation is that the closing speed of the exhaust valve should be large, but the exhaust valve The greater the speed when the disc is about to be completely closed, the greater the impact force of the valve disc on the bearing exhaust hole, and the reliability of the exhaust valve disc will be severely tested, which leads to technical contradictions
