MODULAR FIRE-FIGHTING SYSTEM WITH VORTEX DEVICE OF GAS-LIQUID MIXTURE FORMATION Russian patent published in 2012 - IPC A62C35/00 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire-fighting engineering. Modular fire-fighting system with vortex device of gas-liquid mixture formation contains a vessel with a fire extinguisher, a trigger balloon with gas, 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 with gas. Supply of extinguishing agent is carried through a vortex element made in the form of a perforated conical spiral. Supply of a gas-liquid mixture into the central pipeline is carried out from the bottom of the chamber to the discharging device of the extinguishing agent with a safety valve. The pipe of the mixing chamber is connected to a device of filling in of the fire extinguisher and the pressure indicator unit. The triggering balloon is equipped with a lock-start gear of an electric or a thermo-mechanical starter. Each node of the distribution network of the flow division is equipped with a standard tee-joint or a device of distribution of a special construction. Each sprinkler or sprinklers unit is equipped with a device of orientation in one or two planes.

EFFECT: increased speed of fire-extinguishing system.
