摘要： PROBLEM TO BE SOLVED: To achieve an effective initial fire extinguishment with a limited water loss by injecting the optimum atomized water from a dual fluid nozzle to match various liquid supply sources and gas supply sources.
SOLUTION: The system comprises a compressor or a cylinder (high pressure gas supply source) 2, a pump (liquid supply source) 4 which sucks up extinguishing water from a water storage tank 3, a dual fluid nozzle 7 made to communicate with the compressor 2 and the pump 4 respectively through an air feed pipe 5 and a liquid feed pipe 6 having a dual fluid one-piece type hose 11, a gas flowrate adjustor (flowrate adjustor) 8 provided on the upstream side of the liquid feed pipe 5, a liquid flowrate adjustor (flowrate adjustor) 9 provided on the liquid feed pipe 6 and a dual fluid simultaneous open/close valve 10 disposed separately on the downstream side of the air feed pipe 5 and the liquid feed pipe 6. Compressed air from the compressor 2 and water (liquid) from the pump 4 being adjusted in flow with the gas and liquid flowrate adjustors 8 and 9 are mixed with the dual fluid nozzle 7 and the optimized atomized water is injected to flames to extinguish fire.

摘要： PROBLEM TO BE SOLVED: To achieve quick extinguishing of fires with effective prevention of damage by water by mobilizing fire extinguishing activities immediately responding to the situations at fire sites. SOLUTION: Two-fluid fire extinguisher 1 is provided with a back-carried type air cylinder 2 (high pressure gas cylinder), a flexible air hose (gas hose) 4 with one end part thereof connected to the air cylinder 2 through a manual open/close valve 3, a flexible water hose (liquid hose) 7 with one end part thereof detachably mounted on a water supply source (liquid supply source) 6 through a pipe joint 5 and a two-fluid nozzle 10 connected to respective other end parts of the air hose 4 and the water hose 7 through pipe joints 8 and 9. Water forced from the water supply source 6 and compressed air from the air cylinder 2 are mixed with the two-fluid nozzle 10 and turned to misty water to be injected to flames thereby extinguishing fires.

摘要： PROBLEM TO BE SOLVED: To provide a light weight and small, two-fluid sprayer which carries out fire extinguishing work quickly and accurately by facilitating operations. SOLUTION: The two-fluid sprayer 1 is provided with a gas-liquid mixing part 2 having a gas introduction tube 9 and a liquid introduction tube 10, an injection part 3 connected to the tip part of the gas/liquid mixing part to inject air (gases) and water (liquid) mixed by the gas/liquid mixing part 2 as misty water, gas piping 4 and liquid piping 5 both rigid respectively connected to the gas introduction tube 9 and the liquid introduction tube 10 of the gas/liquid mixing part 2 and bent downward in the course thereof and open/close valves 6 and 7 which are installed on the respective piping 4 and 5 and operated simultaneously with an operation lever 11 to open or close ducts of the piping 4 and 5. The respective piping 4 and 5 are connected to the gas hose and the liquid hose from the gas supply source and the liquid supply source through pipe joints 11 and 12 and the open/close valves 6 and 7 are opened simultaneously by operating the operation lever 11 to inject the misty water to flames from the injection part 3 thereby extinguishing fires.
