FIELD: chemical industry; the devices for the gaseous fire extinguishing of the facilities and premises. ^ SUBSTANCE: the invention is pertaining to the devices of the gaseous fire extinguishing of the facilities and premises and directed to simplification of the design, decrease of metal consumption, simplification of the mounting of the automated installation of the fire extinguishing. The technical result of the invention is reached by that the automated installation of the fire extinguishing contains the cryogenic reservoir with liquefied gaseous fire extinguishing composition, the evaporator of the fire extinguishing composition made in the form of the vessel with the heat-accumulating packing connected to the cryogenic reservoir through the controlled valve, the distributing pipelines for feeding of the fire extinguishing composition, sensors of the fire detection, the control unit connected with the sensors. The automated installation of the fire extinguishing includes the pulsing gasifier - pressure transducer including the fire-extinguishing composition evaporator , the vessel of which is made in the form of the reservoir for evaporation of the liquefied gaseous fire-extinguishing composition under the high pressure and partially filled with the profiled heat-accumulating packing, the throttling device connected between the vessel of the evaporator and the distributing pipelines, the pipe duct for prevention of the overpressure in the vessel of the evaporator through the valve between the vessel of the evaporator and The distributing pipelines, and also the unit of the program control over the vales of the pulsing gasifier- pressure transducer connected to the control unit of the automated installation of the fire extinguishing and with the controlled valve between the vessel and of the evaporator and the cryogenic reservoir. At that the distributing pipelines are made in the form of the pipe ducts for feeding of the fire-extinguishing composition under the high pressure. ^ EFFECT: the invention ensures simplification of the design, decreased metal consumption, simplification of the mounting of the automated installation of the fire extinguishing. ^ 6 cl, 1 dwg |
