のである。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention rapidly extinguishes an extinguishant filled in an extinguishant container in an extremely short time to prevent an explosion from occurring or suppress a fire. The present invention relates to a container valve for fire extinguishing equipment.
ガス系の消火剤を使用する消火設備のガス系の消火剤に
は、二酸化炭素、ハロン1301がよく知られている。この
ようなガス系の消火剤を消火剤容器に充填し、火災発生
時に消火剤を消火剤容器より急速に放出するための消火
設備用容器弁として、例えば、実開昭60−93100号公報
に示されるような、差圧式容器弁がよく知られている。Carbon dioxide and halon 1301 are well known as the gas-based fire extinguishing agent for fire extinguishing equipment that uses the gas-based fire extinguishing agent. Such a gas-based fire extinguisher is filled in a fire extinguisher container, and as a container valve for fire extinguishing equipment for rapidly discharging the fire extinguisher from the fire extinguisher container, for example, in Japanese Utility Model Publication No. 60-93100. Differential pressure container valves, as shown, are well known.

るだけでなく、弁体の質量が大きくなり、全開後に弁体
を停止させる必要があるため、弁体及び弁箱の強度を上
げる必要があり、容器弁全体の大きさも非常に大きなも
のになってしまう欠点があった。In the differential pressure type container valve, the larger the valve seat diameter, the larger the valve body, and the time required for full opening is 10
It was over 0ms. This is the time required to fully open
The time to open the pilot valve, the time to release the pressure by the pilot valve, the time to move the valve element to the fully open position,
This is because the respective times are accumulated. Further, when the valve body becomes large, not only does it take time to move to the fully open position, but also the mass of the valve body becomes large and it is necessary to stop the valve body after fully opening, thus increasing the strength of the valve body and the valve box. However, there is a drawback that the size of the entire container valve becomes very large.
また、弁を通過する流路がエルボ状のＬ型とならざるを
得ない構造であるため、全開時の消火剤の流れ損失が大
きく、短時間で消火剤を大量に放出するには、見かけの
口径より大きな口径を必要とする等の問題点があった。Also, since the flow path that passes through the valve must be an elbow-shaped L-shaped structure, the flow loss of the extinguishant at the time of full opening is large, and it is apparent that a large amount of extinguishant should be released in a short time. However, there is a problem in that it requires a larger diameter than the above.
本発明は、極めて短時間で消火剤を放出することができ
るとともに、小形で、保守の容易な消火設備用容器弁を
提供することを目的とする。An object of the present invention is to provide a container valve for fire extinguishing equipment, which is capable of releasing a fire extinguishing agent in an extremely short time and is small in size and easy to maintain.
上記目的を達成するため、本発明は、消火剤を充填した
消火剤容器の出口に破裂板を配置した消火設備用容器弁
において、容器本体と破裂板の間の消火剤放出路に面し
て、開放封板を介して点火部への通電により高圧のガス
を発生するガス発生剤を配設したガス発生器を配置した
ことを要旨とする。In order to achieve the above object, the present invention is a container valve for fire extinguishing equipment in which a rupture plate is arranged at the outlet of a fire extinguisher container filled with a fire extinguisher, facing the fire extinguisher discharge path between the container body and the rupture plate, and opening. The gist of the present invention is to dispose a gas generator in which a gas generating agent that generates high-pressure gas by energizing the ignition part through a sealing plate is arranged.
以下、本発明を図面に示す実施例に基づいて説明する。 Hereinafter, the present invention will be described based on embodiments shown in the drawings.

ホルダー10を回動させることにより、破裂板９の取り替
えを自在とする。The base side of the valve box 2 is screwed into the screw 5 of the opening 4 of the container body 1 filled with the fire extinguishing agent via the packing 3 to form the valve box 2
The injection nozzle 6 is attached to the tip of the
The valve box 2 and the injection nozzle 6 are integrated with the container body 1, and the valve box 2 and the injection nozzle 6 constitute the outlet of the extinguishant container.
6a is an ejection port formed in the ejection nozzle 6. The rupture plate 9 is fixed to the injection nozzle 6 side of the valve box 2 via the gasket 8 by the holder 10. The inner peripheral surface of the holder 10 has a hexagonal hole shape, and the holder 10 is rotated by using a tool having a corresponding hexagonal cross section, so that the rupture plate 9 can be replaced freely.
弁箱２の中央部側面にアダプター11をねじ部15を介して
着脱自在に取り付け、アダプター11にガス発生器12を弁
箱２の中心に向けてガスが発生するように装着する。ま
た、アダプター11の先端と弁箱２の周壁との間にガスケ
ット14を介して開放封板13を挟持させる。An adapter 11 is detachably attached to the side surface of the central portion of the valve box 2 via a screw portion 15, and a gas generator 12 is attached to the adapter 11 so that gas is generated toward the center of the valve box 2. Further, the open sealing plate 13 is sandwiched between the tip of the adapter 11 and the peripheral wall of the valve box 2 via the gasket 14.
ガス発生器12は、アジ化化合物を主成分とする固形のガ
ス発生剤12Bと点火部12Aからなり、点火部12Aに2A程度
の電流を流すと、ガス発生反応を開始し、発生ガス圧が
一定圧力以上となるとカバー12Cが破れ、さらに開放封
板13を破壊すべく構成する。The gas generator 12 is composed of a solid gas generating agent 12B containing an azide compound as a main component and an ignition part 12A.When a current of about 2A is applied to the ignition part 12A, a gas generation reaction is started, and the generated gas pressure is When the pressure exceeds a certain level, the cover 12C breaks, and the open sealing plate 13 is further broken.
上述の如く点火部12Aの点火でガス発生剤12Bがガス発生
反応して開放封板13を破壊し、開放状態とすることによ
り、弁箱２の中心部、すなわち容器本体１と噴射ノズル
９との間の消火剤放出路Ａに向け、ガス発生器12で発生
した高圧のガスが噴出するようにする。As described above, when the ignition part 12A is ignited, the gas generating agent 12B reacts with the gas generation to break the open sealing plate 13 and bring it into an open state, so that the central portion of the valve box 2, that is, the container body 1 and the injection nozzle 9. The high-pressure gas generated in the gas generator 12 is jetted toward the fire extinguishing agent discharge path A between.
発生ガスの圧力は弁箱部分の圧力のみ急激に上昇させる
ため、破裂板９が全開し、破片はホルダー10内周に張り
付く。Since the pressure of the generated gas sharply increases only the pressure of the valve box portion, the rupture plate 9 is fully opened and the fragments stick to the inner circumference of the holder 10.
これにより、容器本体１内の消火剤は、短時間のうちに
噴出ノズル６の噴出口6aより放出される。As a result, the fire extinguishing agent in the container body 1 is discharged from the ejection port 6a of the ejection nozzle 6 within a short time.
なお、ガス発生器のガス発生剤は火薬類であっても差し
支えない。また破裂板９は一枚板で構成されるものとし
たが、二枚以上の複合部材から構成されても良いことは
もちろんである。The gas generating agent of the gas generator may be explosives. Further, although the rupture plate 9 is composed of a single plate, it goes without saying that it may be composed of two or more composite members.

し、ガス発生器12の圧力波を最大限に利用できるように
したため、少量のガス発生剤で破裂板９を全開させるこ
とができる利点を有している。Due to the gas generated by the gas generator 12, the pressure wave propagates faster in the liquid phase portion than in the gas phase portion and is attenuated according to the distance from the gas generator. In the embodiment shown in the drawings, the inside of the valve box 2 is filled with the liquid phase portion of the extinguishant when the outlet of the extinguishant container is arranged downward. Therefore,
The pressure liquid generated from the gas generator 12 becomes maximum inside the valve box 2 and is significantly attenuated inside the container 1. Therefore, it is not necessary to increase the pressure resistance of the container 1 more than necessary, and the rupture plate 9 is arranged in the immediate vicinity of the gas generator 12 so that the pressure wave of the gas generator 12 can be utilized to the maximum. This has the advantage that the rupturable plate 9 can be fully opened with a small amount of gas generating agent.
なお、ガス発生剤の量を変えることにより、容器本体の
出口の方向を下向き以外としても本発明の目的を達成で
きることはもちろんである。Of course, the object of the present invention can be achieved by changing the amount of the gas generating agent even when the outlet of the container body is not directed downward.
