FIELD: fire-fighting facilities.SUBSTANCE: invention relates to fire-fighting equipment. The modular automatic fire-fighting system comprises a vessel, a starting cylinder with working gas, a pipeline network with sprinklers. The vessel with a fire extinguishing agent is fastened by the brackets to the wall of the premise and has a device of gaseous phase discharge and a device of forming the gas-liquid mixture of the vortex type. The discharge device is combined with dimensional probe for the fire extinguishing agent. The device of forming is made in the form of a conical mixing chamber with a tangential inlet in the form of a flexible hose in the upper part. The hose is connected to the starting cylinder with the working gas (e.g. nitrogen or CO). Supply of the extinguishing agent is carried by a vortex element which is formed as a conical perforated spiral. Supply of gas-liquid mixture to the central pipe is carried out from the lower part of the chamber, which is connected to a drain device of fire extinguishing agent. The vertical pipe of the mixing chamber is connected to fire extinguishing agent filling device and the pressure signal indicator. Each node of the distribution network comprises a distribution device of gas-liquid mixture. For separation of the flow in two directions a standard T-socket is used. Each sprinkler or set of sprinklers is equipped with an orientation unit in one or two planes.EFFECT: increased operation speed of fire-fighting system.2 dwg |
