Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to an electric valve with a temperature measurement function. Background Art

[0002] An electric valve is a valve driven by electricity, usually used to control the flow of fluid in a pipeline. They can be controlled by a remote control system, an automated system, or manual operation. The advantages of electric valves include precise flow control, easy integration into automated systems, remote operation, and improved system reliability and safety. This makes electric valves widely used in industries, construction, heating, air conditioning, water treatment, and other fields. There are at least the following disadvantages in the use of existing electric valves: 1. When the existing electric valves are in use, the temperature of the fluid in the valve body is not monitored, which makes it difficult for managers to know the internal situation, which will cause the internal temperature of the electric valve to be too high and cause damage; 2. The existing electric valves lack protection for the actuators. Most of the actuators are set at the upper end of the valve body and exposed to the outside, which is easy to be damaged by bumps. Therefore, we have launched an electric valve with temperature measurement function. Utility Model Content
