WATER FIRE EXTINGUISHING SYSTEM Russian patent published in 2018 - IPC A62C37/00 

FIELD: fire safety.

SUBSTANCE: invention relates to the field of fire fighting equipment, namely to fire extinguishing agents, in particular to automatic water (foam) fire extinguishing installations. In the water fire extinguishing system containing a pipeline distribution network equipped with sprinkler sprinklers with controlled start-up, a fire alarm control and control device, to which a fire alarm loop is connected with fire detectors included in it and a signal line, which includes starting initiation devices electrically connected to controlled sprinkler sprinklers, and said pipeline distribution network is divided into zones, the system is additionally equipped with addressable remote start devices corresponding to each allocated zone, that are included in another signal line connected to the receiving-control and fire control device, wherein the first and second signal lines are combined, and the zones are formed in such a way that each successive half overlaps the previous one, and around each of the zones, except for the extreme zones, four zones are separated, each of which covers a quarter or half of the first, and in the upper part of the sprinkler body with controlled start-up there is a sleeve on which the sprayer is rigidly fixed, consisting of a lower cup rigidly connected to the sleeve and with an upper dissipating cup, on the conical surface of which the slits are made, the lower cup being connected to the upper dissipating cup by means of at least three inclined spokes, and a diffuser is provided in the interior of the diffuser in the form of a body of revolution, for example a ball attached by at least three radially horizontally arranged flat petals to the inclined spokes, the axis of the body of revolution coinciding with the axes of the sleeve and the check valve.

EFFECT: increased reliability of the water fire extinguishing system by means of optimizing the position of the fire extinguishing center relative to the fire site.
