Description

Technical Field

[0001] The utility model belongs to the technical field of valve processing, and in particular relates to a positioning device for an electric valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, and electric valves, etc., which are used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] During the valve processing, the valve needs to be clamped and fixed to ensure the stable processing. At present, the existing valve positioning devices are of various types and complex structures. The existing fixing method is: first fix the valve A side flange to process the B side flange hole, and then fix the B side flange after the B side flange hole is processed to process the A side flange hole. As a result, the valve needs to be disassembled and fixed many times during the processing, which is time-consuming and labor-intensive, resulting in low processing efficiency and poor practicality.

[0004] Therefore, in order to solve the above problems, it is necessary to design a positioning device for an electric valve. Utility Model Content
