Abstract

A detection device for an electronic expansion valve disclosed by the present invention comprises a shell, the top of the shell is fixedly connected with a permanent magnet motor, the output end of the permanent magnet motor penetrates into the shell and is movably connected with a needle valve, the right side of the shell is communicated with an inlet pipe, and the bottom of the shell is communicated with an outlet pipe. A flow sensor is arranged at the top of the surface of the outlet pipe, a flow velocity sensor is arranged at the bottom of the right side of the outlet pipe, and the detection end of the flow velocity sensor penetrates into the outlet pipe. Data are detected through the infrared sensor, the flow velocity sensor and the flow sensor, then the opening value is compared and displayed through the data by the control unit, and therefore the electronic expansion valve has the advantage of being convenient to detect and display, and the problem that in the using process of an existing electronic expansion valve, the opening of a valve needle cannot be detected, and the service life of the electronic expansion valve is prolonged is solved. Therefore, the problem that the user cannot know the opening information of the valve needle is solved, and the use of the user is facilitated.

Description

technical field [0001] The invention relates to the technical field of electronic expansion valves, in particular to a detection device for electronic expansion valves. Background technique [0002] The expansion valve is an important part of the refrigeration system, and the electronic expansion valve is a common type of expansion valve. However, the existing electronic expansion valve cannot detect the opening of the valve needle during use, causing users to It is impossible to know the opening degree information of the valve needle, which affects the use of the user. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a detection device for electronic expansion valve, which has the advantages of convenient detection and display, and solves the problem that the valve needle cannot be adjusted during the use of the existing electronic expansion valve. The...
