AUTOMATIC FIRE-FIGHTING SYSTEM Russian patent published in 2018 - IPC A62C35/00 

FIELD: fire safety equipment.

SUBSTANCE: this is achieved by the fact that in an automatic fire extinguishing system containing a vessel in which the extinguishing agent is stored, a starting cylinder with a working gas, a network of pipelines with sprinklers, the vessel is fixed by brackets to the building construction of the room and has a gas phase relief device combined with a measuring probe for the extinguishing agent, and is equipped with a vortex-type gas-liquid mixture forming device which is made in the form of a conical mixing chamber with a tangential inlet at the top, by means of a flexible high-pressure hose, working gas to the vessel from the starting cylinder, while the supply of the extinguishing agent is carried out along a vertical branch pipe coaxial with the axis of the conical chamber, and the gas-liquid mixture supply to the central pipeline is carried out from the lower part of the chamber connected to the extinguishing agent discharge device combined with a safety valve, wherein the mixing chamber vertical branch pipe is connected to the fire extinguishing agent filling device and the pressure indicator, and starting cylinder is located close to the fire-extinguishing agent container and equipped with stop-starting device of electric or thermal mechanical start, and each distribution network node includes a gas-liquid mixture distribution device, wherein when dividing the flow into two directions, a standard tee is used, and when the flow is divided into three or more directions, the distribution device of a special design is used, for example a chamber type, and every sprinkler or unit of sprinklers is equipped with orientation device in one or two planes.

EFFECT: technical result is faster operation of fire extinguishing system.
