The intermediate valve coupling port 21 is formed in the main body 10 and the main body 10, which penetrates the through-hole 11 of the main body 10 and engages with the intermediate valve 2. A lever 20 having a lever 22 extending out of the main body 10 through a slot 12 of the main body 10 and a trigger for operating the lever 20 ( 31) and when the user set time elapses, the lever unit 20 is automatically rotated to the intermediate valve locked position and the user rotates the lever unit 20 to the intermediate valve open position for a predetermined time. The lever operating mechanism 30 in which the stopper 32 is maintained to maintain the state. By setting the desired time, the user rotates by the operation of the internal mechanism 41 and the mechanical device 41, the trigger operation for operating the trigger 31 of the lever operating mechanism 30 on the lower surface A timer 40 made of a case 42 having a sphere 42a is fixed, and the mechanism 41 of the timer 40 is fixed so that the case 42 is rotated relative to the internal mechanism 41. It is to include a mechanical device fixing part 50 is fixed to the mechanical device 41 through the opening of the upper case 42 and coupled to the main body 10 at the bottom.

The main body 10 is coupled to the gas pipe 1 by screwing with the coupler 13 in the position where the intermediate valve coupler 21 of the lever 20 is coupled to the intermediate valve (2).

The circumferential length of the slot 12 of the main body 10 is such that the lever 22 can rotate when the intermediate valve 2 opens and closes.

The intermediate valve coupling hole 21 of the lever part 20 is formed with a substantially rectangular groove, and the end of the intermediate valve 2 is inserted into the groove so that the intermediate valve 2 is operated by the operation of the lever part 20. Open and close

The lever operating mechanism 30 includes a trigger 31 actuated by the trigger actuating mechanism 42a of the timer 40, a compression spring 33 for applying an elastic force to the trigger 31, and the trigger 31 A stopper 32 for releasing the stop state of the lever 20 so that the lever 20 moves from the open position to the locked position when operated, and a compression spring 34 for applying an elastic force to the stopper 32, on one side. Lever part operation part 35 and the lever part operation part which the latching opening 35a which catches the lever 22 of the lever part 20 is formed, and the projection 35b which engages with the said stopper 32 is formed in the other side.
