FIELD: fire-prevention facilities.
SUBSTANCE: method of fire-fighting in closed facilities, which consists in creation in the fire seat of fire extinguishing agent through discharge from the cylinder and spraying of fire extinguishing agent under pressure through the outlet valve, on the cylinder the outlet valve is mounted, set to actuation from impact on it of metered excessive pressure significantly exceeding the normal pressure in the cylinder, then on the cylinder also the device of generation of the said excessive pressure is mounted, provided with a working element, the cylinder is charged with the extinguishing agent, then inert gas is injected into the cylinder to normal pressure, less pressure of actuation of the outlet valve, and at the time of occurrence of ignition in the device of generation of the additional pressure the working element is initiated, transforming it into the gaseous state, is introduced into the cylinder, the excessive pressure is generated in the cylinder, which is sufficient for actuation of the outlet valve, and the latter is opened, and discharging the fire extinguishing agent from the cylinder, it is sprayed in the ignition area in the form of fine mist. The group of inventions also relates to an automatic fire extinguisher used in this method.
EFFECT: group of inventions provides a guaranteed complete and almost instantaneous opening the fire extinguisher outlet, and also accelerated expulsion of the extinguishing agent and a higher rate of spraying the composition.
