FIRE EXTINGUISHING SYSTEM WITH DRENCHER Russian patent published in 2016 - IPC A62C31/02 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting equipment. Fire extinguishing system with drencher sprinkler consists of a network of transmission and distribution pipelines, water tank and water intake system with a filter and a pump and two automatic water feeders. Drencher comprises casing and sprayer. Housing is designed as a central hub with an external hexagon and an internal cylindrical surfaces. Sprayer is composed of sleeve, to which by means of arches is fixed a socket. Socket is part of spherical surface confined by inner and outer hemispheres. On spherical surface with its outer side, there are slots. In peripheral part of hemisphere there are orifices. 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 with outer hexagon and internal cylindrical surfaces are inclined towards outlet orifices with their axes intersecting at point located on axis of central bushing, and make an acute angle to said axis in plane of drawing.

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