MODULE OF FIRE-EXTINGUISHING WITH DRENCHERS Russian patent published in 2014 - IPC A62C35/00 

FIELD: fire safety.

SUBSTANCE: in the fire-extinguishing module comprising a housing made of profiled steel bands, in which a cylinder with a siphon tube is vertically mounted, divided by the liquid level to the liquid and gas volumes, and filled with fire-extinguishing liquid under pressure of the compressed gas, a pressure switch. At the outlet of the cylinder there is a pyrotechnic type shut-off device electrically connected through the control unit with smoke detectors and hydraulic sprayer connected to the siphon tube, the sprayer is made in the form of a drencher, the drencher comprises a housing with a screw located coaxially in the lower part of the housing and a fitting with a cylindrical opening for supplying liquid located in the upper part of the housing, connected with a diffuser axisymmetric to the housing and the fitting, the screw is molded in the housing to form a cylindrical chamber located over the screw coaxially to the diffuser and connected to it sequentially. The screw is provided with a central orifice, and the outer surface of the screw is at least a single-treaded helical groove and is located inside the housing, and the output of the helical groove is connected to the output conical chamber, which end is attached to the plate sprayer, which consists of at least two plates perpendicular to the axis of the screw and parallel to each other, one of which, the first plate has a central opening which diameter is equal to the diameter of the larger of the openings of the output conical chamber, and the second plate is made continuous and fixed to the first through at least three fastening elements comprising a screw, a nut and fixing calibrated washer mounted between the plates and operating as a regulatory link controlling the gap.

EFFECT: improving the efficiency of fire-extinguishing by increasing the speed of operation.
