FIELD: firefighting equipment.
SUBSTANCE: invention can be used in industrial and civil facilities, including those with increased fire hazard for localizing fires, as well as for effective fire extinguishing in rooms using automatic fire extinguishing systems. To release the container for the gas fire extinguishing agent of the gas fire extinguishing device, first connect the container for the gas fire extinguishing agent through the outlet of the container with the adapter for the gas fire extinguishing device. The adapter contains a passage channel mating with the outlet hole with a branch connected to a fitting with a check valve. The outlet of said passage channel is provided with a locking element and is connected to the locking and starting device of the gas fire extinguishing device. The non-return valve has a cone-shaped part that enters the cavity of the fitting. The fitting is configured to be connected to a pressure control device. The adapter is connected through the passage channel to the said locking and starting device of the gas fire extinguishing device, consisting of a housing for a pusher, on one side connected to the adapter locking element, and on the other side connected to the atomizer. The body for the pusher is a hollow rod with a fastening hollow base. There are coaxial grooves for the fastening pin in the lower part of the rod and partially in the fastening hollow base. A pusher spring-loaded by a spring is fixed inside the rod, which is a parallelepiped truncated at one of its ends, containing a transverse through hole for a mounting pin at its non-truncated end. The transverse through hole is made coaxial with the grooves. Through this hole, by means of a fastening pin, the pusher is fixed in a spring-loaded position through the grooves. The atomizer is a hollow cylindrical cap, strung on the housing for the pusher and fixed through the holes in its lower part by means of the pin through the grooves and hole. In the upper part of the atomizer there is a cavity for placing a lock. In the upper part of the atomizer, spray holes are made on the sides. The lock forms a stop for the rod and prevents the spring from expanding. The destruction of the lock leads to the decompression of the spring. The decompression of the spring leads to the movement of the pin along the grooves in the direction of the locking element. The pusher is placed in such a way that when the pin moves, it moves in the direction of the locking element, pierces the locking element of the locking nut and releases the extinguishing agent. The container is emptied of its contents using a check valve.
EFFECT: exclusion of the possibility of clogging the passage channel of the needle with parts of the membrane and elimination of the possibility of narrowing the passage channel of the needle due to icing; and, as a result, increasing the reliability of the shut-off and starting device for the fire extinguishing device; and, as a result, increasing the reliability of the fire extinguishing device as a whole; and also, as a consequence, the exclusion of an increase in the exit time of the gas fire extinguishing agent.
