FIELD: fire-fighting means. ^ SUBSTANCE: invention relates to fire-fighting engineering. Modular system of fire extinguishing contains a vessel with fire extinguisher, a triggering balloon with gas, a pipeline network with sprinklers. The vessel with a device of release the gas phase is fixed by the brackets to the building construction of the premises. The device of release of the gas phase, with a measuring probe for the extinguishing agent is equipped with a device of formation a gas-liquid mixture of vortex type. The device of formation the mixture is made in the form of a conical mixing chamber with a tangential inlet at the top, made in the form of a flexible high pressure hose connected to the triggering balloon filled with working gas. Supply of extinguishing agent is carried through a vortex element coaxial to the chamber and made in the form of a perforated conical spiral. Supply of a gas-liquid mixture into the central line is carried out from the bottom of the chamber connected to the discharging device of the extinguishing agent combined with a safety valve. The triggering balloon is equipped with a lock-start gear of an electric or a thermo-mechanical starter. Each node of the distribution network includes a standard tee-joint for distribution of gas-liquid mixture. Each sprinkler or sprinklers unit is equipped with a device of orientation in one or two planes. ^ EFFECT: increased speed of fire-extinguishing system. ^ 2 cl, 2 dwg |
