MODULAR FIRE EXTINGUISHING SYSTEM WITH VORTEX APPARATUS FOR GENERATING GAS-LIQUID MIXTURE Russian patent published in 2016 - IPC A62C2/00 

FIELD: fire safety equipment.

SUBSTANCE: invention relates to firefighting equipment. Fire extinguishing system comprises a vessel with fire-extinguishing substance, starting cylinder with working gas, network of pipelines with sprinklers. Each of said sprinklers is in form of a drencher having a housing and a sprayer. Housing is designed as a central hub with an external hexagon and an internal cylindrical surfaces. To one of end sides is mounted a feed branch pipe and to another- a sprayer. Sprayer is in form of a sleeve with internal diameter equal to inner diameter of feed branch pipe, by arcs arranged along conical surface, attached to socket. Socket is part of spherical surface confined by inner and outer hemispheres. Centre of hemisphere lies on line connecting axis of central sleeve and axis of feed pipe. On spherical surface from its outer side, there are slots with their axes located at radial lines relative to hemisphere. In peripheral part of hemisphere are orifice holes whose centres lie in plane parallel with center plane of hemisphere. Axially symmetric to spray element there is a blocking valve made in form of a ball fixed by a spring located inside central sleeve. In side surface of central sleeve are made inclined towards outlet orifices with their axes intersecting at point located on axis of central sleeve, and making acute angle to said axis in plane of drawing.

EFFECT: technical result is faster operation of fire extinguishing system.
