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

FIELD: fire safety.

SUBSTANCE: in the water extinguishing system comprising a pipeline distribution network, equipped with sprinklers with the controlled start, the receiving-control and the fire control unit, which is connected to the fire loop with the fire detectors and signal line comprised in it, which comprises the devices of initiating the start, electrically connected to controlled sprinklers, and the said pipeline distribution network is divided into zones, and the system is additionally provided with address devices for remote start, corresponding to each designated zone, which belong to the other signal line connected to the receiving-control instruments and fire control unit. The first and second signal lines are joined, and the zones are formed so that each successive one overlaps the half of the previous one. Around each of the zones, except for the extreme, four more zones are isolated, each of which overlaps the quarter or half the first, and in the upper part of the housing of the sprinkler with controlled start the sleeve is located, on which an atomiser is rigidly fixed, comprising a lower cup rigidly connected with the sleeve and the upper cup-splitter, on which conical surface the slits are made. The lower cup by at least three inclined spokes is connected to the upper cup-splitter, in the atomiser the splitter is additionally provided, made in the form a body of revolution, e.g. a ball, fastened by means of at least three radial, horizontally located, flat lobes to the inclined spokes. The body of revolution of the axis coincides with the axes of the sleeve and the shut-off valve.

EFFECT: increasing the reliability of water extinguishing system due to optimising the position of the centre of the fire extinguishing with respect to fire.
