KOCHETOV DRENCHER FIRE FIGHTING SYSTEM Russian patent published in 2016 - IPC A62C31/02 

FIELD: recovery operations.

SUBSTANCE: invention relates to firefighting equipment. Technical result is achieved by the fact that the drencher fire fighting system consisting of a network of main and distributing pipelines filled with liquid fire extinguishing composition, with deluge heads, there is a water supply source, which is a water tank and water intake system with filter and a pump, two automatic water feeder, and in the main feed line signal is installed turbine, the drencher head comprises a hollow body in the form of a sphere with inlet and outlet throttling element; the body is arranged between branch and case, fixing it so that the plane of the inlet opening of the housing is located perpendicular to axis of symmetry of branch and case, and the output throttle is composed of cylindrical throttling holes uniformly located on the casing spherical surface, the axes of which are arranged on radial lines connecting the centre of the casing spherical surface with centre holes, note that here that perforation factor of perforated spherical surface of the body is within optimal range of - 0.5÷0.8.

EFFECT: higher efficiency of fire extinguishing ensured by introducing high-speed elements in the common circuit for automatic fire extinguishing system.
