Exhaust valve plate assembly and compressor

Abstract

The invention relates to an exhaust valve plate assembly and a compressor. The exhaust valve plate assembly comprises an exhaust valve plate and a buffer piece; the exhaust valve plate is suitable forbeing connected to a first object with an exhaust port, and when exhausting is completed at the exhaust port, the exhaust valve plate moves rapidly in the closing direction under the effect of resetforce; when the exhaust valve plate is closed, buffer force of the buffer piece acts on the exhaust valve plate; and the direction of the buffer force is opposite to the direction of the reset force,and the magnitude of the buffer force is smaller than that of the reset force. The exhaust valve assembly can be high in speed at the initial time of closing of the exhaust valve plate, closing is quick without being delayed, meanwhile, the speed of the exhaust valve plate can be decreased rapidly at the end of closing, thus impact of the exhaust valve plate on the exhaust port is reduced, the reliability of the exhaust valve plate is improved, and the service life of the exhaust valve plate is prolonged. The compressor is provided with the exhaust valve plate assembly, the power of the compressor is not affected, and the reliability of the compressor is further improved.

Description

technical field [0001] The invention relates to the field of gas compression, in particular to an exhaust valve assembly and a compressor. 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 exhaust structure of the compressor is one of the main links in the optimization of the energy efficiency of the compressor. The existing exhaust structure is an elastic valve plate arranged at the exhaust port. When the compressor releases pressure and exhausts, the high-pressure gas rushes through the elastic valve plate from the exhaust port to exhaust. After the exhaust is completed, the elastic The valve plate resets under the action of its own elasticity to close the exhaust port. The design of the exhaust structure directly affects the smoothness of the exhaust. At the end of the exhaust of the compressor, the faster the reset speed when the theoretical exhaust valve ...

Problems solved by technology

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the exhaust valve plate in the prior art has a large closing speed and a large impact force on the exhaust hole, thereby providing a valve with a high initial closing speed, Discharge valve plate assembly and compressor that can reduce the impact force on the discharge hole by reducing the final closing speed
