本発明は消火薬剤を内蔵した自動消火装置の配管システ
ムに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a piping system for an automatic fire extinguishing device containing a fire extinguishing agent.
既存の老人養護ホーム等でスプリンクラ−設備を設置で
きない特殊な状況にある社会福祉施設に対してはパッケ
ージ型の自動消火設備を設置することが義務づけられて
いる。Social welfare facilities, such as existing nursing homes for the elderly, which are in special circumstances where sprinkler equipment cannot be installed, are required to install packaged automatic fire extinguishing equipment.
そしてこのようなパッケージ型の自動消火設備としては
例えば第４図に示すように加圧ガス容器（１）と薬剤貯
蔵容器（２）からなる加圧式の消火装置格納箱（５）を
施設の廊下等に設置し、消火の対象となる各部屋には熱

、これら噴出ノズル（１３）と薬剤貯蔵容器（２）の出
口配管とを電磁式選択弁（１１）を設けた薬剤供給管（
１８）で連結したものがある。As shown in Fig. 4, an example of such a package type automatic fire extinguishing system is to install a pressurized fire extinguishing system storage box (5) consisting of a pressurized gas container (1) and a chemical storage container (2) in the hallway of the facility. Each room to be extinguished is equipped with a heat detector (15) and a plurality of chemical jetting nozzles (13), and these jetting nozzles (13) are connected to the outlet piping of the chemical storage container (2). A drug supply pipe equipped with an electromagnetic selection valve (11) (
18) are connected.

示す。According to such fire extinguishing equipment, heat detectors (15
) detects a fire, the control panel unit (3') in the containment box (5) operates to open the electromagnetic selection valve (11) corresponding to that room, and pressurized gas releases extinguishing agent to the room. Fire is extinguished by emitting fire from the nozzle (13) in the room. In the figure, (18) indicates a warning device such as a buzzer, (4) a drive device for discharging extinguishing agent, and (16) a backup power source.
ところが上記パッケージ型自動消火装置の噴出ノズルは
天井等に設置し、薬剤供給管をこれらノズルに連通ずる
ため天井裏で引き回すが、これら薬剤供給管は施工のし
易さ等の理由から通常細径の銅パイプが用いられている
。従って消火対象の部屋数が多く、また特に既設の建物
に新たにこのような消火設備を設置する場合は、建物内
の既設の多数の電気配線や給排気設備用のダクトをかわ
しながら銅パイプを配管するためパイプの延長距離が長
くなり、消火薬剤が銅パイプ内を流れる際の圧力損失は
大きくなってしまう。このため薬剤貯蔵容器と噴出ノズ
ルとの設置位置は比較的近い距離でなければならず、従
って規模の大きい建物では薬剤貯蔵容器は多数必要とな
るので、設置場所の問題や設置費用も高いという問題が
あった。However, the spray nozzles of the above-mentioned packaged automatic fire extinguishing system are installed on the ceiling, etc., and the chemical supply pipes are routed behind the ceiling to communicate with these nozzles, but these chemical supply pipes are usually small in diameter for reasons such as ease of construction. copper pipes are used. Therefore, there are a large number of rooms to be extinguished, and especially when installing new fire extinguishing equipment in an existing building, copper pipes must be routed around the building's many existing electrical wiring and ducts for air supply and exhaust equipment. Due to the piping, the length of the pipe is long, and the pressure loss when the extinguishing agent flows through the copper pipe becomes large. For this reason, the installation positions of the drug storage container and the ejection nozzle must be relatively close to each other. Therefore, in a large building, a large number of drug storage containers are required, resulting in problems in the installation location and high installation costs. was there.
また同じ薬剤貯蔵容器からの配管系統内において選択弁
で区分された２つの消火対象部位で火災を感知し、それ
ぞれの選択弁が開いた時には薬剤貯蔵容器から消火対象
部位までの遠近の違いによりそれぞれの配管での圧損が
異なる。In addition, within the piping system from the same chemical storage container, a fire is detected at two areas to be extinguished that are separated by selection valves, and when each selection valve opens, each fire is detected depending on the distance from the chemical storage container to the area to be extinguished. The pressure drop in the piping is different.
このため薬剤貯蔵容器から遠い部位の噴出ノズルから放
射される消火薬剤の量は少なく、さらに放射スピードも
遅くなってしまい、各部位で消火薬剤の散布のされ方に
バラツキが生じていた。For this reason, the amount of extinguishing agent emitted from the spray nozzle at a location far from the agent storage container is small, and the speed of the extinguishing agent is also slow, resulting in variations in the way the extinguishing agent is sprayed at each location.
本発明はこれに鑑み種々検討の結果、上記問題点を解消
した自動消火装置の配管システムを開発したものである
。In view of this, and as a result of various studies, the present invention has developed a piping system for an automatic fire extinguishing device that solves the above problems.
即ち本発明は消火薬剤貯蔵容器と消火を必要とする複数
の部位に設置した噴出ノズルとをそれぞれ選択弁を設け
た薬剤供給管で連結し、各部位に設置した感知器での火
災の感知によりその部位の選択弁を開いて自動的に消火
薬剤を噴出する消火装置において、薬剤供給管を複数の
ブロックに区分してそれぞれのブロック内の薬剤供給管
をブロック用選択弁を設けたメイン配管で連結し、さら
に薬剤貯蔵容器と各ブロック用選択弁とを連結してなる
ことを特徴とするものである。That is, the present invention connects a fire extinguishing agent storage container and spray nozzles installed at a plurality of locations requiring fire extinguishing through agent supply pipes each equipped with a selection valve, and detects the fire with a detector installed at each location. In a fire extinguishing system that automatically sprays extinguishing agent by opening a selection valve in that area, the agent supply pipe is divided into multiple blocks and the agent supply pipe in each block is connected to the main piping equipped with a block selection valve. In addition, the drug storage container and the selection valve for each block are connected.
このように消火範囲の全体をいくつかのブロックに区分
し、ブロック内の各消火対象部位の近傍に特に薬剤供給
管より径の大きいメイン配管を設置しておくことにより
、そのブロック用選択弁が開いた時にはメイン配管内に
供給される消火薬剤の圧損はほとんど無い。By dividing the entire fire extinguishing range into several blocks and installing main piping with a diameter larger than the chemical supply pipe near each part of the block to be extinguished, the selection valve for that block can be When opened, there is almost no pressure loss of the extinguishing agent supplied into the main pipe.
またそのメイン配管から各部位の噴出ノズルまではいず
れも短い距離となる。このため選択弁を設けた薬剤供給
管でこの間を連結すれば薬剤貯蔵容器からの遠近に無関
係に消火薬剤がブロック内の全ての部位のノズルから−
様な状態で放出されることになる。Also, the distance from the main piping to the jet nozzles of each part is short. For this reason, by connecting these with a chemical supply pipe equipped with a selection valve, the extinguishing agent can be supplied from nozzles in all parts of the block, regardless of the distance from the chemical storage container.
It will be released in various conditions.
次に本発明の一実施例を説明する。 Next, one embodiment of the present invention will be described.

表示灯を点灯させ、同時に警報ブザーを鳴らして格納箱
表示灯を点滅させる構成とした。For example, if only one heat sensor (15) in a certain area to be extinguished is activated, the alarm buzzer in the fire extinguisher storage box (5) will sound, the storage box indicator light will blink, and the activated heat sensor (
15) An abnormality in a certain part is notified, and only when another heat sensor (15) in that part is activated, the drive device (4) is activated and the selection valve (!1) of the part and its Block selection valve (8) for the block to which the part belongs
) or (9) is opened, the discharge indicator light of the control panel unit (3) is lit, and at the same time an alarm buzzer sounds and the storage box indicator light flashes.
また制御盤ユニット（３）の機能としてはさらに次のよ
うな機能も有する。先ず駆動装置（４）には安全装置が
設けてあり、この安全装置が働いている場合即ちＬＯＣ

Ｎ側に成る場合は上記格納箱表示灯を点灯（感知器が作
動した時には点滅）させておく。Furthermore, the control panel unit (3) also has the following functions. First, the drive device (4) is equipped with a safety device, and if this safety device is working, that is, the LOC
If it is on the K side, turn on the safety device indicator light on the control panel unit (3), and if the safety device is released, that is, 0PE.
If it is on the N side, keep the storage box indicator light above lit (flashing when the sensor is activated).
さらに駆動装置（４）にはテスト用押しボタン（１７）
を設けてあり、安全装置をＬＯＣＫ側にしてこのテスト
ボタンを押すと装置が正常に働いていれば駆動装置（４

る。Furthermore, the drive device (4) has a test push button (17).
If the safety device is set to the LOCK side and this test button is pressed, if the device is working normally, the drive device (4
) solenoids and all selection valves can be operated manually, the discharge indicator light will illuminate and the containment box indicator light will flash.
また制御盤には遠隔の手動操作で任意の選択弁を開放し

みに薬剤を放射できる機能をもたせることができ、さら
にどの部位の熱感知器が働いて薬剤放射を行ったかを外
部の集中管理室等に知らせることも可能である。In addition, the control panel can be equipped with the function of opening an arbitrary selection valve by remote manual operation and ejecting chemicals only to the desired area to be extinguished from the ejection nozzle leading to the valve, and the heat sensor of It is also possible to notify an external central control room or the like whether the drug has been activated and emitted the drug.
なお本実施例では加圧式の消火装置について説明したが
、蓄圧式消火装置を用いた場合も同様な構成となる。In this embodiment, a pressurized fire extinguishing system has been described, but a similar configuration can be obtained when a pressure accumulating fire extinguishing system is used.
このように本発明によれば、薬剤貯蔵容器から各消火対
