Description

Technical Field

[0001] The utility model relates to the technical field of electric valves, in particular to an electric valve which can automatically reset after power failure. Background Art

[0002] The action torque of electric valves is larger than that of ordinary valves. The speed of electric valves can be adjusted. They are simple in structure and easy to maintain. They can be 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. Traditional pneumatic valves are not easily damaged by getting stuck due to the buffering characteristics of the gas itself during the operation process, but they must have an air source, and their control system is also more complicated than that of electric valves; This type of valve should generally be installed horizontally in the pipeline.

[0003] If a power outage occurs during use of the electric valves on the market, the electric valves will remain in the state at the moment of the power outage. This will result in the electric valves that need to be closed not being closed during the power outage, causing the liquid in the pipeline to be out of control and resulting in economic losses.
