Problems solved by technology

However, when the refrigerant flows through the electronic expansion valve, since the liquid refrigerant is often mixed with gas, the sound of bubble burst will appear after the refrigerant flows through the valve port, which makes the electronic expansion valve produce noise when it is in use.

Abstract

The invention discloses an electronic expansion valve and refrigeration equipment. The electronic expansion valve comprises a valve shell, a valve element base, and a nut; the valve element base is installed on the valve shell, and a valve port is formed in the valve element base; and the nut is installed on the valve shell, and a silencing gap is formed between the nut and the valve element base.According to the electronic expansion valve, noise can be effectively lowered, the risk that the valve needle gets stuck is reduced, and the using effect of the electronic expansion valve is improved.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to an electronic expansion valve and refrigeration equipment for regulating fluid flow. Background technique [0002] In the refrigeration cycle system, an electronic expansion valve is usually installed between the evaporator and the condenser to change the flow rate of the refrigerant medium in the refrigeration system. However, when the refrigerant flows through the electronic expansion valve, since the liquid refrigerant is often mixed with gas, there will be a sound of bubble burst after the refrigerant flows through the valve port, which makes the electronic expansion valve produce noise when it is in use. [0003] The above content is only used to assist in understanding the technical solution of the invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide...
