WATER CURTAIN FIRE-EXTINGUISHING PLANT Russian patent published in 2011 - IPC B05B1/26 A62C31/02 

FIELD: fire safety.

SUBSTANCE: water curtain fire-extinguishing plant additionally comprises the main water feeder with a filter submerged into a source connected to a manifold line, and a make-up system. The make-up system is installed in parallel to the main water feeder line and includes a make-up pipeline of an auxiliary water feeder and the auxiliary water feeder. A monitoring signal system includes a monitoring signal valve and a signal device. The manifold pipeline is connected to a network of distribution pipelines, where spray drencher heads are installed. Each head is made as a nozzle with a through hole and a threaded part changing into an end circular collar, axisymmetric to the body. The threaded nozzle is connected to a spray device by means of the end circular collar, to which two volumetrical stiffening ribs of bent shape are fixed. The diameter of the circular collar surface, to which two ends of volumetrical stiffening ribs are connected, is at least 3 times more than the diameter of the spray device surface, to which two other opposite ends of the volumetrical stiffening ribs are connected. The spray device is made as a tab, which represents a cylindrical bushing, to which a part of the spherical surface is fixed with the radius that at least 10 times more than the radius of the cylindrical bushing.

EFFECT: increased efficiency of fire extinguishing due to addition of quick-acting elements to the common circuit of the automatic fire-extinguishing system.
