SPRINKLER FIRE EXTINGUISHING SYSTEM Russian patent published in 2017 - IPC A62C31/02 B05B1/26 

FIELD: fire safety.

SUBSTANCE: invention relates to fire-fighting equipment and can be used in extinguishing fires. In a sprinkler fire extinguishing system the sprinkler consists of a base, which is connected with at least two arc-shaped holders to retain a bushing with a spreader fixed on it. Spreader is configured as a diffuser with a bent towards the base belt with tabs arranged along generating lines of the belt conical surface. Inside the spreader there is an additional sprayer made in the form of a cup attached by means of at least three radial, horizontally arranged flat tabs to the inner surface of the spreader. Cup axis coincides with axes of a through channel of the nozzle and the bushing. Inner cavity of the cup is directed towards the bushing. Glass flask with its lower end rests on a valve via a resilient gasket fixed on the outer end surface of the valve. Valve rests on the base in the form of a nozzle with a taper thread and a through channel. Glass flask with its upper end rests on the holder installed in the lower part of the bushing with the spreader fixed on it. Holder is installed in the lower part of the bushing with a gap. Sprayer cup of the sprinkler represents a surface of a truncated cone equidistant and congruent to the outer surface of the cup.

EFFECT: technical result is increased efficiency of fire extinguishing by introducing high-speed elements in the common circuit of the automatic fire extinguishing system.
