Problems solved by technology

However, when the diameter of the exhaust port becomes larger, the rebound cover of the valve plate will be sunken inward on the exhaust port, the deformation of the valve plate will increase, and the phenomenon of wear and tear will deteriorate. more prone to breakage

Abstract

The invention discloses an exhaust valve assembly of a compressor, a compressor and refrigeration equipment, wherein the exhaust valve assembly of the compressor comprises: a valve seat, an exhaust port is arranged on the valve seat, and the diameter of the exhaust port is d ;Valve plate, one end of the valve plate is connected with the valve seat, the other end of the valve plate is covered on the exhaust port to open and close the exhaust port, the thickness of the valve plate is t, the ratio of t to d γ=t / d, γ Satisfy: [0.035, 0.039]∪[0.025, 0.029]; and the lift limiter, the lift limiter is set on the side of the valve plate away from the exhaust port. According to the exhaust valve assembly of the compressor of the present invention, by limiting the ratio of the thickness t of the valve plate to the diameter d of the exhaust port, the requirement of the maximum operating frequency can be met, and at the same time, a better energy efficiency level can be obtained.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an exhaust valve assembly of a compressor, a compressor and refrigeration equipment. Background technique [0002] During the working process, the exhaust valve assembly of the compressor realizes exhaust through the elastic deformation of the exhaust valve plate. When the gas pressure in the compression chamber is greater than the external pressure, the exhaust valve will open, and the compression chamber will be exhausted. After the exhaust is completed, the gas pressure in the compression chamber will be lower than the external pressure, and the exhaust valve will rebound and cover it again. At the exhaust port, the outside gas will not flow back into the compression chamber, so that the gas can move in one direction. The exhaust port is the discharge channel of the air flow. In order to improve the efficiency of the compressor, the thickness of the valve seat...
