SELECTION VALVE FOR EXTINGUISHING FIRE

PROBLEM TO BE SOLVED: To provide an artificial operation tool for a selection valve which automatically supply and jetting gas for extinguishing fire by a controlled system by sensing the breaking-out of a fire. SOLUTION: When the selection valve is inoperable because of an electrical and electromagnetical defect, a managing person easily operates the valve to manually supply and jet gas at the same time of an alarming sound to speedily extinguish a fire in its early stages by a simple operating method to prevent leading to a big fire and to guide evacuation by the alarming sound to minimize the generation of causalities. In constitution where the projecting tip of an actuator 31 pushes a lever 53 to angularly displace an operation bar 5 to remove a stopper 4 to discharge compressed gas for opening a valve, a pin 73 is connected to an L-shaped clearance groove 54 and when a fire is generated, a safety pin 74 is detached to push-in the cover to fit into a hexagonal surface 55 to angularly displace the bar 5.
