In daily use, the valve body can be opened and closed by the switch, and a double protection effect is achieved by the rotation connection of the knob and the switch. When the valve needs to be opened, the magnet needs to be placed inside the groove first. At this time, the trigger rod is attracted by the magnetic force of the magnet, so that the trigger rod moves upward along the inside of the slot until it is clamped inside the linkage hole. At this time, the trigger rod is simultaneously located inside the slot and the linkage hole. At this time, the closure of the switch can be controlled by rotating the knob. In daily use, the valve body can be connected to the pipeline through the connecting pipes at both ends.
