Problems solved by technology

[0002] In the related technology, one end of the filter is fixedly connected to the connecting pipe (inlet pipe or outlet pipe), and the other end is connected to the electronic expansion valve, so as to reduce abnormal noise and filter foreign matter, and the fixing methods of each connection are welded. , leading to more solder joints, cumbersome processing, and higher processing costs
Moreover, it is easy to reverse the two ends of the filter during on-site assembly, which requires rework and re-disassembly and welding, which will damage the filter, cause waste of materials, and generate installation costs

Abstract

The invention discloses an electronic expansion valve and refrigeration equipment. The electronic expansion valve comprises a valve body, two guide pipes and multiple filtering devices, wherein the guide pipes are connected with the valve body; each guide pipe comprises a guide pipe body; and the multiple filtering devices comprise first filters; and the first filters are installed in the guide pipe bodies and are used for filtering fluid passing through the guide pipe bodies. According to the technical scheme provided by the invention, the machining process is simplified, and the number of welding spots is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic expansion valves, in particular to an electronic expansion valve and refrigeration equipment. Background technique [0002] In the related technology, one end of the filter is fixedly connected to the connecting pipe (inlet pipe or outlet pipe), and the other end is connected to the electronic expansion valve, so as to reduce abnormal noise and filter foreign matter, and the fixing methods of each connection are welded. , leading to more solder joints, cumbersome processing, and higher processing costs. Moreover, it is easy to reverse the two ends of the filter during on-site assembly, which requires rework and re-disassembly and welding, which will damage the filter, cause waste of materials, and generate installation costs. Contents of the invention [0003] The main purpose of the present invention is to provide an electronic expansion valve and refrigeration equipment, aiming at simplify...
