FIRE SPRINKLER Russian patent published in 2012 - IPC B05B1/26 A62C31/02 

FIELD: fire-fighting means.

SUBSTANCE: invention relates to fire equipment and can be used in industrial and civil objects with high fire danger, for localisation of fire sources, as well as for effective fire fighting in industrial premises with use of automatic fire extinguishing systems. In the fire sprinkler the housing is designed as a nozzle with a through hole and a threaded part. In the through hole of the nozzle there is a sleeve with a filter mesh attached to it. The threaded nozzle through an axisymmetric bracket is rigidly connected to a hollow cylindrical sleeve with internal thread, which interacts with the clamping screw. The clamping screw through the elastic pad presses a glass flask to the poppet valve. The bracket consists of two vertical volumetric enforcement ribs and two oblique prismatic ribs rigidly connected with them. The glass flask is rests on the valve via an elastic pad attached to the outer end surface of the valve, which through the chain is connected with one of the volumetric enforcement ribs. On the other side of the sleeve, perpendicular to its axis, a spray device in the form of rosette with a central hole and petals arranged relative to each other with a gap is fixed with screws.

EFFECT: increased efficiency of fire-extinguishing through the introduction of spray device, which eliminates the flow turbulence of fire extinguishing fluid or foamgenerator solution.
