Zusammenfassung: | PROBLEM TO BE SOLVED: To inspect function of a fire extinguishing device without detaching a pressure regulator, a relief valve or the like from the device.SOLUTION: This fire extinguishing device includes: a pressurizing gas cylinder; a pressure regulator connected to the pressurizing gas cylinder; fire extinguishing agent containers connected to the pressure regulator, and discharging a fire extinguishing agent filled therein; a fire-extinguishing hose having the base end connected to the fire extinguishing agent containers, and jetting the fire extinguishing agent from a fire-extinguishing nozzle provided at the tip; a relief valve preventing boosting in normal time in the fire extinguishing agent containers, and holding boosting of the fire extinguishing agent containers by pressurized gas introduced from the pressure regulator. A manual gate valve which is normally open and is closed during the inspection to shut off a flow passage between the pressure regulator and the fire extinguishing agent containers is provided between the pressure regulator and the fire extinguishing agent containers. The relief valve is provided between the pressure regulator and the gate valve. |
