Description

Technical Field

[0001] The utility model relates to the technical field of security, and specifically to a warning mechanism and a safety device based on industrial Internet. Background Art

[0002] Electric ball valve is an important actuator in industrial automation control system. Electric ball valve is a gate that rotates around the axis of gate rod according to the movement of gate disc. The change of gate seat opening is proportional to the stroke of gate 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] In the prior art, electric ball valves often use sealing collars to seal pipelines. However, due to the friction between the ball and the two sealing surfaces of the gate seat during the opening and closing process, the sealing collar is easily scratched, and the high temperature in the pipeline will also damage the sealing collar, which will affect the sealing performance and service life, and is not easy to repair. The water leakage caused by the wear of the rubber ring is relatively small, and the pipeline is closed, which is not easy to detect and difficult to inspect. Utility Model Content
