Description

【０００１】
【発明の属する技術分野】
本発明は、飲料水供給や非常用水確保のための水槽にあって、これら給水設備における地震時の給水配管破損による貯留水流出を防止するための緊急遮断弁の設置構造に関するものである。
【０００２】
【従来の技術】
飲料水供給や非常用水確保のための水槽はパネル単位体による組立式又は一体式のものであって、主として地震時に貯留水の流出を防止するために緊急遮断弁が設置されているが、省スペ−スの関係からこの遮断弁は水槽の内側に設置されることが多い。この場合、遮断弁を支持するために遮断弁の固定部を水槽の底部に、遮断弁からの給水取出口を水槽の側面に固定するのが一般的であった。
【０００３】
図２は組立式水槽におけるかかる遮断弁の支持法を示す概要図であり、２１は水槽の側部、２２は水槽の底部であり、遮断弁２３の固定部２４は底部２２に固定され、側部２１に遮断弁２３の給水取出口２５を固定したものである。
この遮断弁２３は図示しない地震感知器によって地震が感知されると、これを制御部２６に伝え、予め制御部２６に入力された初期値との差を演算し、初期の値以上となった場合にこれを遮断弁２３に伝達して給水取出口５を遮断する。
【０００４】
しかるに、地震発生にあっては水槽の側部２１と底部２２との揺れが同一であれば水槽の側部２１及び底部２２に跨がって固定された遮断弁２３も同じように揺れることとなりそれほど問題は生じないが、夫々の揺れが異なった場合には大きな問題が生じ、この場合には遮断弁２３の固定部２４と給水取出口２５とが別々の揺れをすることとなる。即ち、遮断弁２３における固定部２４と底部２２との取付部位及び給水取出口２５と側部２１との取付部位に異なった方向に大きな外力が加わることとなる。
【０００５】
このため、取付部位に用いられるボルトが折れたり抜けたりし、場合によっては水槽が破損することもあり、例え遮断弁２３が正常に機能して水槽外部への給水を遮断したとしてもこの破損部から貯留水が流出してしまうという事態となってしまう。更には、遮断弁２３が大型となった場合には、取付面の形状の違いや静水圧による取付面の撓み量の違い等により２つの取付部位が異なる設置環境となり、固定部２４又は給水取出口２５の周辺より貯留水の漏水が懸念される。
【０００６】
【発明が解決しようとする課題】
本発明は以上のような従来技術に鑑みてなされたものであり、地震等の発生にあっても遮断弁の取付部位に不具合が生じない遮断弁の設置構造を提供するものである。
【０００７】
【課題を解決するための手段】
請求項１に記載の本発明の要旨は、水槽内部に緊急遮断弁を設置した水槽内への遮断弁設置構造であって、前記水槽の底面に取付けられたエルボ管と、前記エルボ管と接続された緊急遮断弁と、前記水槽の底面に取付けられ前記緊急遮断弁の給水取出口と同一面で固定される遮断弁固定部と、を有することを特徴とする水槽内への遮断弁設置構造にかかるものである。請求項２に記載の本発明の要旨は、前記水槽の底面が、一枚のパネル単位体であることを特徴としている。請求項３に記載の本発明の要旨は、前記遮断弁固定部が、前記水槽の底面にボルト及びナットによって固定されていることを特徴としている。
【０００８】
【発明の実施の形態】
本発明は上記したように水槽への遮断弁の給水取出口と固定部を同一面に設けることを特徴とするものであって、このため、水槽に設置される遮断弁及びエルボ管、更には水槽が地震時に一体となって同じ動きをとる設置構造となったものである。又、給水取出口と遮断弁固定部を同一面に取付けたことは取付面形状が同じであり、かつ、水圧による撓み変位量も同一となり完全な一体化が形成され取付部位からの貯留水の漏水の懸念もなくなる。
【０００９】
特に水槽がパネル単位体を用いて組立てた組立式水槽の場合は同一パネルに給水取出口と遮断弁固定部を取付けるとより効果的となる。
【００１０】
【実施例】
以下、本発明を実施例をもって更に詳細に説明する。
図１は本発明の実施例を示す概念図である。図中、符号１は組立水槽の側面でありパネル単位体にて構成されている。２は底面であり、これ又パネル単位体にて構成されている。３は緊急遮断弁であり、その固定部４はこの例では底面２にボルト及びナットにて取付けられ、給水取出口５も又エルボ管６を介して底面２に取付けられたものである。図中、７、８は取付用のボルト及びナットである。これらが取付けられた底面２は一枚のパネル単位体であり、２枚以上のパネル単位体に跨がっていないことが好ましいことは言うまでもない。図中、符号１１は給水取出口５より水槽外部に水を給水するための短管であり、これに更に図示しない鋼管が接続されて配水がなされることとなる。
【００１１】
本発明の緊急遮断弁取付構造は以上の構成をもつものであり、地震の発生の際にも遮断弁３の固定部４と給水取出口５が同一の面に取付けられているためにその地震に対する揺れが全体として取付面と同一の揺れとなり、この揺れによって固定部に不具合を生じることが極めて低減したものである。
【００１２】
【発明の効果】
本発明は以上の構成を有するものであり、水槽内に設置された緊急遮断弁は水槽と完全に一体化された構造となり、地震時や静水圧による動きによっても水槽の破損や漏水の懸念がなくなるという大きな特徴を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to a structure for installing an emergency shut-off valve in a water tank for supplying drinking water or securing emergency water, and for preventing stored water from flowing out due to a water supply pipe breakage during an earthquake in these water supply facilities.
[0002]
[Prior art]
Water tanks for drinking water supply and emergency water securing are assembled or integrated by panel units, and an emergency shut-off valve is installed mainly to prevent outflow of stored water during an earthquake. Due to space concerns, this shut-off valve is often installed inside the aquarium. In this case, in order to support the shut-off valve, it is common to fix the shut-off valve fixing portion to the bottom of the water tank and the water supply outlet from the shut-off valve to the side surface of the water tank.
[0003]
FIG. 2 is a schematic diagram showing a method for supporting such a shut-off valve in the assembly type water tank, 21 is a side part of the water tank, 22 is a bottom part of the water tank, and a fixing part 24 of the shut-off valve 23 is fixed to the bottom part 22. A water supply outlet 25 of the shutoff valve 23 is fixed to the part 21.
When an earthquake is detected by an earthquake detector (not shown), this shut-off valve 23 transmits this to the control unit 26, calculates the difference from the initial value previously input to the control unit 26, and becomes equal to or greater than the initial value. In this case, this is transmitted to the shutoff valve 23 to shut off the water supply outlet 5.
[0004]
However, in the event of an earthquake, if the shaking of the side 21 and the bottom 22 of the aquarium is the same, the shutoff valve 23 that is fixed across the side 21 and the bottom 22 of the aquarium will also sway in the same way. Although there is not much problem, a big problem occurs when the respective swings are different. In this case, the fixing portion 24 of the shutoff valve 23 and the water supply outlet 25 swing separately. That is, a large external force is applied to the attachment portion of the shut-off valve 23 between the fixed portion 24 and the bottom portion 22 and the attachment portion between the water supply outlet 25 and the side portion 21 in different directions.
[0005]
For this reason, the bolt used for the attachment part may break or come off, and the water tank may be damaged in some cases. Even if the shutoff valve 23 functions normally and shuts off the water supply to the outside of the water tank, this damaged part It will be the situation that the stored water will flow out from. Furthermore, when the shut-off valve 23 becomes large, the two mounting parts have different installation environments due to a difference in the shape of the mounting surface, a difference in the amount of bending of the mounting surface due to hydrostatic pressure, and the like. There is concern about leakage of stored water from around the outlet 25.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the prior art as described above, and provides a shut-off valve installation structure in which no trouble occurs in the mounting portion of the shut-off valve even when an earthquake or the like occurs.
