INSTALLATION FOR FIRE-EXTINGUISHING WITH WATER CURTAIN Russian patent published in 2013 - IPC B05B1/04 B05B1/26 A62C31/02 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to fire-fighting equipment. The installation for fire-extinguishing with water curtain comprises a main water feeder with the filter lowered to the source, and connected to the main pipeline. Besides the installation comprises a feeding system mounted parallel to the line of the main water feeder and comprising pipeline of feeding of the auxiliary water feeder and the auxiliary (automatic) water feeder. The control and signaling system comprises an alarm control valve and a warning device, such as in the form of an alarm horn. The main pipeline is connected to the network of distribution pipelines in which the drenchers are mounted. Each drencher is made in the form of a sleeve with a supply pipe, a valve and an atomising element. The housing is made in the form of a central hub with external hexagonal and internal cylindrical surfaces. From two end surfaces of the central hub a female screw is made. An inlet branch is mounted axially to one of the end surfaces through the safety nut. The spraying element is mounted on the other end surface, which is made as a hub which inner diameter is equal to the inner diameter of the inlet branch. The hub is mounted to the socket, by means of arcs located on a conical surface, which is a part of a spherical surface bounded by the inner and outer hemispheres. The center of the hemisphere is on the line connecting the central hub axes and the inlet branch axis. On the spherical surface from its outer side at least three slots are made, which axes are located on the lines radial with respect to the hemisphere. In the peripheral part of the hemisphere there are at least three orifices which centers lie in a plane parallel to the center line of the hemisphere, which is perpendicular to the axis of the inlet branch. The blocking valve is located axially to the spraying element, which is made in the form of a ball fixed by a spring located inside the central hub, to the conical surface, made at the end of the inlet branch facing the sawing element.

EFFECT: increased efficiency of fire-fighting due to introduction of high-speed elements in the overall automatic fire-fighting system circuit.
