[0002] Electric ball valve is an important actuator in industrial automation control system. Electric ball valve is a valve that rotates around the axis of the valve stem according to the movement of the valve disc. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It is a pipeline pressure element for industrial automation process control.

[0003] The existing patent CN220204817U discloses an electric ball valve for mining, which describes that "a manual module is connected through a manual valve stem. When a power outage occurs in the mine tunnel and the electric drive module is unable to drive the valve body, the operator can manually drive the valve body of the electric ball valve for mining to rotate through the handle ring of the manual module, so that the electric ball valve for mining can be manually operated when the power is off", but the existing electric ball valves generally stop in the original state after power failure, and unexpected losses will still occur if the ball valve is not manually closed in time.

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