PLANT OF AUTOMATIC FIRE EXTINGUISHING WITH CONTROLLED IRRIGATED AREA Russian patent published in 2013 - IPC A62C37/00 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to plants of automatic fire extinguishing. The plant of automatic fire extinguishing with controlled irrigation area comprises sprinklers, fire detectors, lock-start gear and pipeline. The sprinklers have an electric start. The pipeline is with the extinguishing liquid. The detectors are made address analog, as well as the control devices and control line of the sprinkler. The sprayer comprises a hollow housing with a nozzle and a central core. The housing with a channel for supplying liquid comprises a sleeve rigidly connected to it, at the bottom of which a nozzle is fixed. The nozzle is made in the form of a cylindrical two-stage sleeve which is connected to a central core by a threaded connection. The core consists of a cylindrical part and a hollow cone. The cone is mounted with the annular gap relative to the inner surface of the cylindrical sleeve. The annular space is connected with the channel of the housing for supplying liquid. In the lower part of the cone the sprayer is rigidly fixed with a screw, which is made in the form of a front circular plate which edges are bent in the direction of the annular gap. On the side surface of the cone the orifice axis openings are made, which lie in planes perpendicular to the axis of the cone.

EFFECT: increased efficiency of fire extinguishing by creating a plant of automatic fire extinguishing with controlled irrigated area.
