FIELD: fire-fighting means. ^ SUBSTANCE: in automatic system of fire extinguishing reservoir with fire extinguishing substance is fixed with brackets to construction structure of building and has device of gas phase discharge, combined with measuring probe for fire extinguishing substance, and for formation of vertical gas-liquid mixture is provided with conical mixing chamber with tangential inlet in upper part, by means of flexible hose of high pressure, working gas from starting cylinder. Feed of fire extinguishing substance is realised by vertical branch pipe coaxial with axis of conical chamber, and supply of gas-liquid mixture into central pipeline is realised from lower part of chamber, connected with device of fire extinguishing substance discharge, combined with safety valve, and vertical branch pipe of mixing chamber is connected with device for pouring in fire extinguishing substance and pressure signal, and starting cylinder is located near reservoir for fire extinguishing substance and is provided with stop-starting device. Each unit of distribution network includes device for gas-liquid mixture distribution in form of T-joint or distribution device of special structure, for instance, of chamber type, and each irrigator or unit of irrigators is provided with device of orientation in one or two planes. ^ EFFECT: acceleration of performance. ^ 1 dwg |
