FIELD: fire safety.SUBSTANCE: in automatic fire extinguishing system, comprising a vessel in which the extinguishing agent is stored, the starting cylinder with the working gas, a pipeline network with sprinklers, the vessel is fastened by the brackets to the building structure of the premises and has a device of the gas phase release, combined with a measuring probe for the extinguishing agent, and is provided with the device forming the gas-liquid mixture of vortex type which is made in the form of a conical mixing chamber with a tangential inlet in the upper part, by a flexible hose of high pressure, of the working gas to the vessel from the starting cylinder. Extinguishing agent supply is carried out along the vertical pipe, coaxial with the axis of the conical chamber, and supply of the gas-liquid mixture is carried out into the central pipeline from the lower part of the chamber connected to the draining device of the extinguishing agent, combined with a safety valve. The vertical inlet of the mixing chamber is connected to the extinguishing agent pouring device and the pressure indicator, and the starting cylinder is located next to the vessel for extinguishing agent and is equipped with a lock and release device of the electric or thermomechanical starter, and each node of the distribution network comprises the distribution device of the gas-liquid mixture. When separating the flow into two directions a standard tee s used, and when separation of the flow into three or more directions the distribution device of a special design is used, such as of chamber-type, and each sprinkler or block of sprinklers is provided with a device of orientation in one or two planes.EFFECT: increase in operational speed of the fire extinguishing system.2 dwg |
