WATER EXTINGUISHING SYSTEM Russian patent published in 2012 - IPC A62C37/08 

FIELD: fire fighting means.

SUBSTANCE: invention relates to the field of fire-fighting equipment, namely, the fire fighting means, particularly to automated water extinguishing installations. Water extinguishing system comprises a distribution pipeline network equipped with sprinklers with a controlled start. Control and indicating and fire fighting control device, a fire-warning detector and a signal line, which includes start initiating devices, are connected with sprinklers. And the distribution pipeline network is divided into zones, and the system is additionally equipped with addressable devices of remote start corresponding to each zone, which are included in other signal line connected to the control and indicating and fire fighting control device. The sprinkler body is made in the form of a fitting with a through hole and a threaded part that passes into the end valve part, and the fitting through axisymmetric bracket consisting of two vertical and three-dimensional enforcement ribs and two oblique prismatic edges rigidly connected to them, is connected with a hollow cylindrical sleeve with an inside thread interacting with the clamping bolt. And from the other side to the sleeve, perpendicular to its axis, a spraying device is mounted in the form of a rosette with petals arranged relative to each other with a gap. Axisymmetrically on the side of the fitting opposite to the threaded part, a locking disk valve is located connected to the element of automatic activation which is made in the form of a glass bulb which is a heat lock.

EFFECT: higher reliability of water extinguishing system.
