[0029] When the fire valve is to be used, remove the sealing plug, insert the magnetic end of the opening and closing rod into the hexagonal groove 191 of the rotating rod 19, and then rotate the rotating rod 19. The rotating rod 19 drives the gear 21 to rotate, and the gear 21 drives the gear row 18 to slide, thereby driving the separation block 7 to slide into the gap. At this time, due to the magnetic attraction between the opening and closing rod and the first slider 24, the first slider 24 slides in the sliding channel 22 and resists the pressure sensor module. The spring is stretched, and the pressure sensor module transmits an electrical signal to the control module. The control module controls the solenoid 10 to be energized, thereby generating magnetism and attracting the upper slider 11 and the lower slider 14, so that the upper slider 11 and the lower slider 14 slide into the upper engaging groove and the lower engaging groove, and the upper spring 13 and the lower spring 16 are stretched. Then the upper valve stem 5 is rotated, and the upper valve stem 5 drives the rotating sleeve 8 to rotate, and the rotating sleeve 8 drives the lower valve stem 6 to rotate to open the valve. When use is over, the other end of the opening and closing rod without magnetism is inserted into the hexagonal groove. At this time, the spring resets, releasing the resistance with the first slider 24 and the pressure sensor module. The pressure sensor module transmits an electrical signal to the controller. The controller turns off the solenoid 10 and energizes it. The upper spring 13 and the lower spring 16 reset, driving the upper slider 11 and the lower slider 14 to reset, and then the rotating rod 19 is rotated to drive the separation block 7 to slide out of the gap or to be misaligned with the upper valve stem 5 and the lower valve stem 6. At this time, when the upper valve stem 5 is rotated, the upper valve stem 5 idles. If there is no professional staff, the valve cannot be opened.
