AUTOMATIC FIRE-FIGHTING SYSTEM Russian patent published in 2018 - IPC A62C35/00 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting equipment. This is achieved by the fact that in the automatic fire extinguishing system containing the vessel in which the extinguishing agent is stored, starting cylinder with the working gas, network of pipelines with sprinklers, the vessel is fixed to the building structure of the room by brackets and has a gas phase relief device combined with a measuring probe for a fire extinguishing agent, and is equipped with a vortex-type gas-liquid mixture forming device which is made in the form of a conical mixing chamber with a tangential inlet in the upper part made in the form of a flexible high pressure hose connected to a starting cylinder filled with a working gas (for example, nitrogen or CO₂), and the gas-liquid mixture supply to the central pipeline is carried out from the lower part of the chamber connected to the extinguishing agent discharge device combined with a safety valve, wherein the mixing chamber vertical branch pipe is connected to the fire extinguishing agent filling device and the pressure indicator, and starting cylinder is located close to the fire-extinguishing agent container and equipped with stop-starting device of electric or thermal mechanical start, and each distribution network node includes a gas-liquid mixture distribution device, wherein when dividing the flow into two directions, a standard tee is used, and when the flow is divided into three or more directions, the distribution device of a special design is used, for example a chamber type, and each sprinkler or sprinklers unit is provided with an one or two planes orientation device, and each of the sprinklers is made in the form of a drencher, which base is connected to at least two arched supports, which hold the bushing with the divider fixed on it, made in the form of a diffuser with a belt bent towards the base with a tabs located along the generatrix of the conical surface of the belt, and inside the divider a sprayer is additionally installed, made in the form of a cup fixed to the inner surface of the divider by at least three radial horizontally arranged flat tabs, wherein the cup axis coincides with the axes of the nipple and the bushing through channel, and its inner cavity is directed towards the bushing.

EFFECT: faster operation of fire extinguishing system.
