SPRINKLER FIRE-EXTINGUISHING INSTALLATION Russian patent published in 2013 - IPC A62C3/02 

FIELD: fire prevention facilities.

SUBSTANCE: invention relates to fire-fighting equipment. At that the sprinkler fire-extinguishing installation comprises of a water-supply source, a network of main and distribution pipelines with sprinkler heads, it additionally comprises the main water feeder with the filter placed into the source and connected to the main pipeline, and a charge circuit mounted in parallel to the line of the main water feeder and comprising the pipeline of charge of the support water feeder, and the support (automatic) water feeder, and the control-signal system comprises the control-signal valve and the signal device, such as a sound horn. At that the main pipeline is connected to the network of distribution pipelines, in which the sprinkler heads are mounted. At that the sprinkler head housing is made in the form of a fitting with a through hole and a threaded part, at that in the through hole of the fitting a sleeve is located with a filter mesh fastened to it, at that the threaded fitting by the axisymmetric bracket. At that consisting of two vertical volumetric reinforcement ribs and rigidly connected with them two inclined prismatic ribs it is rigidly connected to a hollow cylindrical sleeve with an internal thread interacting with the clamping screw, which presses through the flexible gasket the glass flask to the poppet valve, at that the glass flask rests on the valve through the flexible gasket. At that it is attached to the outer end surface of the valve, which is connected through a chain to one of the volumetric reinforcement ribs and on the other side to the sleeve perpendicularly to its axis, the spray device is screwed in the form of a socket with the central outlet and the lobes located relative to each other with the gap.

EFFECT: invention is aimed at improving the effectiveness of fire-fighting due to the introduction of high-speed elements in the overall chain of automatic fire-extinguishing system.
