MODULAR SYSTEM OF FIRE FIGHTING WITH VORTEX UNIT OF FORMATION OF GAS-LIQUID MIXTURE Russian patent published in 2014 - IPC A62C35/00 

FIELD: fire-fighting equipment.

SUBSTANCE: in the fire fighting system comprising a vessel in which the fire extinguishing agent is stored, a starting cylinder with the working gas, a pipeline network with sprinklers, the vessel is mounted by the brackets to the building structure of the premise and has a relief device of the gaseous phase combined with the measuring probe for the fire extinguishing agent, and is equipped with a device of forming the gas-liquid mixture of vortex type, which is made in the form of a conical mixing chamber with the tangential inlet in the upper part through a flexible high pressure hose, of the working gas to the vessel from the starting cylinder. The extinguishing agent supply is carried out by the vortex element which is coaxial to the chamber and made in the form of a conical perforated spiral with the perforation coefficient lying in the range of 50÷80%, and feeding the gas-liquid mixture into the central pipeline is carried out from the lower part of the chamber connected to the fire extinguishing agent discharging unit combined with safety valve, at that the vertical pipe of the mixing chamber is connected to the device of filling the fire extinguishing agent and the pressure alarm, and the starting cylinder is located near the vessel for the fire extinguishing agent and is equipped with a lock and release device of electric or thermomechanical start, and each unit of distribution network comprises a distribution device of the gas-liquid mixture, at that in separation of the flow into two directions a standard tee is used, and in separation of the flow into three or more directions the distribution device of a special design is used, for example of a chamber type, and each sprinkler or block of sprinklers is equipped with a positioner in one or two planes.

EFFECT: increased operation speed of the fire extinguishing system.
