SYSTEM OF WATER-BASED FIRE SUPPRESSION Russian patent published in 2013 - IPC A62C37/00 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to the field of fire-fighting equipment, namely, the fire-fighting means, particularly to automated plants of water (foam)-based fire suppression. The system of water-based fire suppression comprises pipeline distribution network, divided into zones, the receiving-control device and the fire control device. The network is equipped with sprinklers with the controlled start. The receiving-control device and the fire control device are connected to the fire loop, which comprises fire alarm units and a signal line. The signal line comprises devices of start initiation, which are electrically connected to the controlled sprinklers. The system is additionally equipped with targeted devices of remote start. The first and second signal lines are combined. The zones are formed so that each successive one overlaps by half the previous one. At the upper part of the sprinkler housing with a controlled start a sleeve is located on which the sprayer is rigidly fixed. The sprayer consists of a lower cup which is rigidly connected to the sleeve. In the upper cup-divider, on the conical surface the slots are made. The lower cup is connected by slanting spokes with an upper cup-divider. Inside the sprayer a divider is additionally installed which is designed in the form of a body of revolution. The divider is attached via radial, horizontal, flat lobes to slanting spokes.

EFFECT: increase in reliability of water-based fire suppression system.
