2 is brought into contact with the guide surface 3b of the stopper plate 3. Then, the cam 6 pushes down the holding plate 16, and the rod 1
Since 0 is lowered, valve holes B and D are opened. When the manual lever 7 is further rotated, the stopper plate 3
After rotating counterclockwise in the figure, the locking hook 3a locks the pin 12 and returns to the original state, allowing the valve pressing mechanism and locking mechanism to return.

効果も奏する。 As described above, the gas leak alarm circuit breaker of the present invention is provided with a magnet at one end of the manual lever, and a reed switch connected in series to the electric circuit of the electromagnetic solenoid at the return position of the manual lever and close to the magnet. Therefore, in the event of a gas leak, once the electromagnetic solenoid is activated, its electrical circuit is cut off, preventing the electromagnetic solenoid from heating up. In addition, even if the manual lever is moved to the return position by mistake or mischief while the alarm is operating, the electromagnetic solenoid will operate again and the valve pressing mechanism and locking mechanism will not return, ensuring that the gas pipe is closed. Can be blocked. moreover,
It also has an explosion-proof effect because open contacts are used in the electrical circuit.
