SPRINKLER FOR FIRE FIGHTING INSTALLATION Russian patent published in 2016 - IPC A62C31/00 

FIELD: salvage operations.

SUBSTANCE: invention relates to firefighting equipment. Technical result is achieved by the fact that the sprinkler fire extinguishing plant consisting of a water supply source, a network of distribution pipelines with sprinkler heads, additionally contains a main water feeder with a filter submerged into the source and connected with the main pipeline, and a feed system installed in parallel to the line of the main water feeder and including a pipeline feeding an auxiliary water feeder and an auxiliary (automatic) water feeder, while the control-signal system includes a control signal valve and a signal device, for example, in the form of an acoustic buzzer; at that, the main pipeline is connected to a network of distribution pipelines, in which there are installed sprinkler heads, every of which is composed in the shape of a nipple with a through hole and a threaded part changing into an end valve part; at that, the nipple, by means of an axially symmetric bracket consisting of two vertical voluminous stiffening ribs and rigidly connected to them two inclined prismatic ribs, is rigidly connected with a hollow cylindrical bushing with internal thread interacting with a clamp bolt which presses a glass tube to a poppet valve; at that, on the other side of the bushing and perpendicularly to its axis there is fixed a sprayer in the form of a socket with petals arranged with a gap relative to each other, while axisymmetrically, on the side of the nipple opposite to the threaded part there is installed a separated by a gasket poppet valve connected with the element triggered automatically in response to excess of preset temperature in the room made in the shape of a glass tube representing a thermal lock.

EFFECT: higher efficiency of fire extinguishing ensured by introduction of high-speed elements into the common circuit of an automatic fire extinguishing system.
