KOCHETOV AUTOMATIC FIRE EXTINGUISHING SYSTEM Russian patent published in 2016 - IPC A62C35/00 

FIELD: salvage operation.

SUBSTANCE: invention relates to firefighting equipment. Technical result is achieved by the fact that in an automatic fire extinguishing system, containing a vessel, in which the fire-extinguishing substance is stored, the starting cylinder with working gas, network pipelines with sprinklers, and the vessel fixed with brackets to the building structure of the room and equipped with gas phase discharge device combined with measuring probe for fire-extinguishing substance, and equipped with a device generating gas-liquid mixture of vortex type, made in the form of a conical mixing chamber with a tangential inlet in the upper part by means of a flexible hose, working gas to the vessel from the launching container, at that, the supply of fire-extinguishing substance is carried out via a vertical branch pipe, coaxial with the axis of the conical chamber, while supply of gas-liquid mixture into the central pipeline is performed from the lower part of the chamber connected with the device for draining the fire-extinguishing substance, combined with a safety valve, at that, the vertical branch pipe of the mixing chamber is connected with a device for pouring of fire-extinguishing substance and a pressure indicator, while the launching cylinder is located close to the container for fire-extinguishing substance and is equipped with a lock-start device for electric or mechanical start-up, and each unit of the distribution network includes a device for distribution of gas-liquid mixture, at that, for separation of flow into two directions there is used a standard tee, while for separation of flow into three or more directions there is used a distribution device of a special design, for example, of chamber type, and each sprinkler or sprinkler unit is equipped with a device for orientation in one or two planes, every sprinkler consists of a hollow cylindrical housing with outer thread for connection to fluid supply distribution nipple and fixed in the lower part of the housing coupling nut with fluid flow splitter, at that, in the housing and coaxially to it a cylindrical bore is made in the upper part of which there is a mesh filter, and in the lower part there is a throttling orifice with a jet, and liquid flow spreader is attached to end surface of the coupling nut and is of pin type in the form of a truncated tetrahedron fixed to end surface of the captive nut, ribs are pins with blades with stops providing for a possibility of their rotation from the flows outgoing from the throttle washer with jet nozzles, while the tetrahedron base ribs are also connected by rods with blades and stops.

EFFECT: faster operation of the fire extinguishing system.
