この考案は、粉末消火剤を放出する加圧ガスの
圧力源として混合ガスを用いる消火器に関するも
のである。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a fire extinguisher that uses a mixed gas as a pressure source for pressurized gas that discharges a powder fire extinguishing agent.
（従来の技術及び問題点）
従来より、粉末消火器の圧力源として炭酸ガス
を液化炭酸ガスとして耐圧容器に充填して使用し
ているが、寒冷地においては放出効率が低下する
欠点があり、また寒冷地における放出効率の低下
しない加圧ガスとして窒素ガスを使用することも
あるが、この場合は法令上の規制を受ける大容量
の耐圧容器を用いることとなり、携帯用の小型の
粉末消火器には採用出来ない。(Prior art and problems) Conventionally, carbon dioxide gas has been used as a pressure source for dry powder fire extinguishers by filling it in a pressure container as liquefied carbon dioxide gas, but this has the disadvantage that the discharge efficiency decreases in cold regions. Nitrogen gas may also be used as a pressurized gas that does not reduce release efficiency in cold regions, but in this case a large-capacity pressure-resistant container that is regulated by law must be used, and a small portable powder fire extinguisher may be used. cannot be adopted.
また、ガスを多くする必要から複数個の炭酸ガ
スの耐圧容器を用いる方法も検討されたが、構造
が複雑となつて実施されていない。 Furthermore, since it was necessary to increase the amount of gas, a method of using a plurality of pressure-resistant containers for carbon dioxide gas was considered, but this method has not been implemented due to the complicated structure.
この考案は、このような問題点を解決するため
に、一つの耐圧容器内に窒素ガスと液化炭酸ガス
を共に充填した圧力ガスを、粉末消火器の加圧源
として使用し、低温時にあつても平常温度時同様
な消火効力の大きい消火器、及び液化炭酸ガスに
窒素ガスを混合することにより耐圧容器内のガス
圧力が高くなることから封板を安全封板にして安
全性を持たせた消火器を提供するものである。 In order to solve these problems, this idea uses a pressure gas filled with both nitrogen gas and liquefied carbon dioxide gas in one pressure-resistant container as a pressurizing source for a dry powder fire extinguisher, and uses it as a pressurizing source for dry powder fire extinguishers. A fire extinguisher with a high fire extinguishing effect similar to that at normal temperature, and a safety seal for safety because the gas pressure inside the pressure container increases by mixing liquefied carbon dioxide with nitrogen gas. Fire extinguishers shall be provided.
（問題点を解決するための手段）
この考案は、すなわち中央部分の肉厚を薄くし

近接して対置したポンチと、このポンチを駆動す

内に液化炭酸ガスと窒素ガスを封入することを特
徴とする混合ガスを封入した耐圧容器を用いる消
火器である。(Means for solving the problem) This invention consists of a pressure-resistant container having a safety sealing plate with a thin wall in the center, a punch placed close to the safety sealing plate, and a drive mechanism for driving the punch. Fire extinguishing using a pressure-resistant container filled with a mixed gas, characterized in that a cap equipped with a lever is attached to a main container containing a fire extinguishing agent, and liquefied carbon dioxide gas and nitrogen gas are sealed in the pressure-resistant container. It is a vessel.
（作用）
一つの耐圧容器に、液化炭酸ガスと窒素ガス充
填した場合、そのガス圧力は窒素ガスを充填した
分だけ圧力が高くなる。その圧力はほぼ液化炭酸
ガスの温度に係わる圧力に平行して高い。(Function) When one pressure-resistant container is filled with liquefied carbon dioxide gas and nitrogen gas, the gas pressure increases by the amount of nitrogen gas filled. The pressure is high, approximately parallel to the pressure associated with the temperature of the liquefied carbon dioxide.
従つてこの耐圧容器に従来使用している液化炭
酸ガス用の一般の封板をそのまま設けたのでは圧
力上危険である。といつてその封板を厚くしたの
では消火器のポンチが刺さらない、そこでこの考
案では封板の中央部分の肉圧を薄くした薄肉部を
持つ安全封板にし、ポンチで容易に開封し、かつ
異常温度上昇の場合はこの薄肉部が自動的に破壊
開封し、耐圧容器内の高圧ガスを安全に放出する
ようにしている。 Therefore, it would be dangerous due to pressure if the conventional sealing plate for liquefied carbon dioxide gas was provided as is in this pressure-resistant container. However, if the sealing plate was made too thick, a fire extinguisher punch would not be able to penetrate it, so in this invention, a safety sealing plate with a thinner part with a thinner wall in the center of the sealing plate was used, which could be easily opened with a punch. In addition, in the event of an abnormal temperature rise, this thin-walled portion will automatically break open and safely release the high-pressure gas inside the pressure-resistant container.
そして消火器操作時レバーを押し下げると、ポ
ンチは安全封板に突き刺ささるが、安全封板は薄
肉部があることにより容易に開封し、高い圧力で
かつ十分なガス量により、低温時でも粉末消火剤
は完全に放射される。 When the lever is pressed down when operating the fire extinguisher, the punch will pierce the safety sealing plate, but the safety sealing plate has a thin wall that makes it easy to open, and the high pressure and sufficient amount of gas extinguishes powder fire even at low temperatures. The agent is completely radiated.
