The moving magnet 601 can be controlled to be located in the control groove 201 through the control valve seat 2, and the moving magnet 601 will not fall, thereby ensuring that the valve body 1 is always in a connected state.

[0032] The electromagnetic assembly includes a fixed magnetic block 9 fixedly connected to the inside of the control valve seat 2, and a coil 10 electrically connected to the fixed magnetic block 9 is fixedly connected to the inside of the control slot 201.

In special circumstances, a signal can be sent to the wireless communication module 12 through the remote center, and the power supply of the electromagnetic component can be cut off through the control module. At this time, the cooperation of the elastic member 8 and the abutment plate 403 can drive the cut-off block 4 to move downward. At this time, the air hole 11 is misplaced, and the flow of the valve body 1 is cut off, which has good safety.
