GAS-WATER FIRE-EXTINGUISHING SYSTEM Russian patent published in 2011 - IPC A62C31/02 B05B7/08 

FIELD: fire-extinguishing facilities.

SUBSTANCE: invention relates to fire-fighting equipment and can b e used in industrial and civil objects with higher fire hazard for localization of ignition focuses. In gas-water fire-extinguishing system for system starting provided is automatic microprocessor station, installed in line of gas supply between pipeline that connects balloons with compressed gas and before reducers. Station is connected with fire-detecting sensors, installed in premises. Irrigator case is made in form of bush. Coaxially to its internal surface fixed is connecting pipe, made in form of bush with thread and conic parts on the ends and canal for compressed gas supply. Perpendicular to case axis to its external surface connected is connecting pipe with canal for water supply, which is connected with ring canal, formed by internal case surface and external surface of connecting pipe for compressed gas supply. Before conic part of connecting pipe for compressed gas supply, coaxially to it, installed is element of gas-water jet formation, made in form of washer. Washer represents detachable impingement plate, fastened on the end of bolt, which interacts with nut. Nut is rigidly fixed on arch-like rod, installed on check-nut, located on external case surface, detachable movable orifice, made in form of bush, is fixed on it by means of thread connection. On its butt end part, facing detachable impingement plate, made is conic hole, which with conic part of connecting pipe for compressed gas supple forms a ring slot for water output. Impingement plate with butt end surface of conic part of part of connecting pipe forms a clearance, which is regulated by means of bolt and nut. Surface of detachable impingement plate, facing conic part of connecting pipe for compressed gas supply, is made concave and spherical.

EFFECT: increase of fire-extinguishing efficiency due to introduction of irrigator, which eliminates turbulisation of fire-extinguishing mixture flow.
