PROBLEM TO BE SOLVED: To provide a fire extinguishing gas spray device having a small size and light weight, being easily manufactured at a low cost, enabling simple unsealing of a fire extinguishing gas cylinder, preventing waste of fire extinguishing gas by temporarily storing the injected fire extinguishing gas, and accurately jetting the gas to a fire source for extinguishing fire.SOLUTION: A cylinder holder 4 is provided to detachably hold a gas cylinder filled with extinguishing gas and sealed with a sealing plate 2 in a mouth part, on one side of a through hole 8. A needle tube 12 capable of breaking a seal of the sealing plate 2 is projected in a shaft cylinder part 10 airtightly inserted in the through hole 8 in a slidable manner. The needle tube 12 and a guide hole 14 which can communicate with the through hole 8 are arranged so as to be able to communicate with a nozzle 27 opened outside. A movable shaft 19 associated with pressing pressure displacement is inserted into the guide hole 14 in a slidable and airtight manner. The through hole 8 is cut off from the nozzle 27 when breaking the seal and the extinguishing gas stays in the through hole 8 and the inside of a seal breaker holder 9. The through hole 8 and the nozzle 27 are brought into communication when the movable shaft 19 is operated and displaced. |
