Abstract

The invention relates to an electronic expansion valve. The electronic expansion valve comprises a valve body for refrigerant throttling, an inlet pipe connected to the valve body, and an attracting device arranged in the inlet pipe for attracting impurities. According to the electronic expansion valve, the attracting device is arranged in the inlet pipe and can attract the impurities driven by aflowing refrigerant, so that the impurities can be reduced or prevented from entering the valve body from the inlet pipe.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an electronic expansion valve. Background technique [0002] Electronic expansion valves are widely used in refrigerators and air-conditioning refrigeration systems to adjust the flow of refrigerant in the refrigeration system. Due to the application of Bondi tube (galvanized steel pipe), the electronic expansion valve used in general refrigerators is prone to iron filings and there is a risk of getting stuck. Contents of the invention [0003] Based on this, it is necessary to provide an improved electronic expansion valve. [0004] The application provides an electronic expansion valve, including: [0005] A valve body for throttling the refrigerant; [0006] an inlet pipe connected to the valve body; and [0007] An adsorption device arranged in the inlet pipe to absorb impurities. [0008] In one of the embodiments, the adsorption device is a permanent ...
