PROBLEM TO BE SOLVED: To provide a fire extinguishing facility capable of preventing a liquid fire extinguishing agent from remaining in a fire extinguishing agent transporting tube and reliably ejecting the liquid fire extinguishing agent in ejection of the liquid fire extinguishing agent.SOLUTION: Pressure gas is supplied from a pressure gas storing container 5 to a fire extinguishing agent storing container 2 by a pressure gas transporting tube 6, and a liquid fire extinguishing agent stored in the fire extinguishing agent storing container 2 is compressed by the pressure gas and discharged from the fire extinguishing agent storing container 2 to the fire extinguishing agent transporting tube 3. The discharged liquid fire distinguishing agent is guided to fire extinguishing subject areas D1 to D3 so that fire is extinguished and put out. A fire extinguishing agent flow path opening/closing valve 8 is provided in the fire extinguishing agent transporting tube 3 and one end of a bypass tube 11 for push-out pressure supplying means 9 is connected to the fire extinguishing agent transporting tube 3 on the upstream side of the fire extinguishing agent flow path opening/closing valve 8, while the other end of the bypass tube 11 is connected thereto on the upstream side of the fire distinguishing agent flow path opening/closing valve 8, so that a pressure to push out the fire extinguishing agent to the downstream side is supplied to the upstream side of the fire extinguishing flow path opening/closing valve 8 in the fire extinguishing agent transporting tube 3 and the liquid fire extinguishing agent remaining on the upstream side of the fire extinguishing agent flow path opening/closing valve 8 in the fire extinguishing agent transporting tube 3 is discharged to the downstream side of the fire extinguishing agent flow path opening/closing valve 8. |
