SPRINKLER FIRE-EXTINGUISHING SYSTEM Russian patent published in 2014 - IPC A62C31/02 

FIELD: fire-prevention facilities.

SUBSTANCE: in the sprinkler fire-extinguishing system consisting of a network of main and distribution pipelines constantly filled with liquid fire-extinguishing agent with sprinklers, the water-supply source which is a water tank and a water intake system with filter and pump, two automatic water feeders, a housing of the sprinkler is made in the form of fitting with the through opening and the threaded part, at that in the through opening of the fitting there is a sleeve with the filter mesh fixed on it, at that the threaded fitting through the axisymmetric bracket consisting of two vertical volumetric reinforcement ribs and two inclined prismatic ribs rigidly connected to them, is rigidly connected to the hollow cylindrical sleeve with the internal thread interacting with the clamping screw which through the elastic pad presses the glass bulb to the poppet valve, at that the glass bulb is supported on the valve through the elastic pad attached on the outer end surface of the valve which is connected through the chain to one of the volumetric reinforcement ribs, and on the other side to the sleeve perpendicular to its axis a spray device in the form of a socket with a central opening and the lobes located relative to each other with a gap is attached with the screws.

EFFECT: improvement of efficiency of fire extinguishing due to the introduction of high-speed elements in the overall chain of automatic fire-extinguishing system.
