FIRE-FIGHTING METHOD WITH THE GAS-LIQUID MIXTURE APPLICATION Russian patent published in 2018 - IPC A62C35/00 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to firefighting equipment. This is achieved by the fact, that in the extinguishing method using a gas-liquid mixture, which is implemented by means of a vessel in which the extinguishing agent is stored, and connecting it with the starting cylinder with the working gas, the vessel, where the fire extinguishing agent is stored, is fixed to the room building structure with brackets and equipping it with a gas phase discharge device, combined with a measuring probe for the fire extinguishing agent, and the vortex type gas-liquid mixture forming device, which is made in the form of a conical mixing chamber with tangential gas inlet in the upper part, then connecting with the working gas high-pressure flexible hose, for example nitrogen or CO₂, to the vessel from the starting cylinder, at that, the gas supply is performed along the vortex element, coaxial to the chamber and made in the form of a conical perforated spiral with a perforation coefficient in the range of 50÷80 %, and the gas-liquid mixture supply into the central pipeline is performed from the chamber lower part connected to the fire extinguishing agent discharge device combined with a safety valve, at that, connecting the chamber vertical branch pipe to the fire extinguishing agent filling device and the pressure indicator, and the formed gas-liquid mixture is directed to the distribution network nodal point along the central pipeline, and then to all sprinklers through the distribution network, wherein each 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.
