WATER FIRE EXTINGUISHING SYSTEM Russian patent published in 2014 - IPC A62C37/00 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to the field of fire-fighting equipment, namely, the means for extinguishing fire, in particular to automated units of water (foam) fire-fighting. In the system of water fire extinguishing, containing pipeline distribution network equipped with sprinklers with controlled start, the receiving-control and management fire-fighting device, which is connected to fire loop with integrated fire detectors and a signal line, which comprises the devices of initiating the start, electrically connected to controlled sprinklers, and the pipeline distribution network is divided into zones, and the system is equipped with additional addressable remote start devices corresponding to each designated area, which are included in the other signal line connected to the receiving-control and management fire-fighting device, the sprinkler housing is made as a fitting with a through hole and a threaded part passing into the end valve part, and the fitting by means of an axisymmetric nozzle consisting of two vertical volume stiffeners and two inclined prismatic ribs rigidly connected to them is rigidly connected to a hollow cylindrical sleeve with an internal thread interacting with a clamping bolt which presses a glass flask to the poppet valve, while on the other side to the sleeve perpendicularly to its axis, the sprayer device is mounted, in the form of rosette with the petals positioned relative to each other with a gap, and axially on the fitting side, opposite the threaded part the lock poppet valve is located through a pad, connected with the element of automatic response to the excess of the given premises temperature, which is made in the form of a glass flask, which is a thermal lock.

EFFECT: increasing reliability of water fire-extinguishing system.
