次に、本発明の非常用貯水槽の操作動作を添付図面に基づいて、以下に説明する。
平常時においては、水は水道管８内を常時開状態の上流側の緊急遮断弁９を経て圧力水槽１内を流通し、下流側の緊急遮断弁９を経て再び水道管８へ流通する。
この場合、バイパス用弁１１は常時閉状態に形成されているから、バイパス管１０には水は流通しない。

In normal times, water flows through the pressure water tank 1 via the upstream emergency shut-off
In this case, since the bypass valve 11 is normally closed, water does not flow through the
At this time, the water tap 3, the fire-extinguishing faucet 4, the air supply pipe 6, and the pressure air valve 7 are closed, the air compressor 5 is stopped, the pressure water tank 1 is full, the
例えば、地震発生による非常時においては、自動的に次の動作を行う。
圧力水槽１の上流側と下流側の緊急遮断弁９が閉、バイパス管１０のバイパス用弁１１が開となると共に送気管６が開となり圧力水槽１に圧力空気が注気され、収容されている水は圧力水となる。必要使用時の条件が圧力水であるということから圧力水槽１の水に圧力を与えることが必要である。
なお、送気管６に設置されている圧力調整弁によって必要圧力を設定する。
次に、圧力水槽１内の圧力水を利用する場合は、給水栓３、消火用水栓４の各手動操作によって開閉し水の供給を行う。
又、地震時の家屋倒壊時にエアジャッキの利用が必要の時は圧力空気弁７に接合する。
For example, in an emergency due to an earthquake, the following operation is automatically performed.
The upstream and downstream
In addition, a required pressure is set by the pressure control valve installed in the air supply pipe 6.
Next, when the pressure water in the pressure water tank 1 is used, the water is opened and closed by manual operation of the water faucet 3 and the fire-extinguishing faucet 4 to supply water.
Further, when it is necessary to use an air jack when the house collapses at the time of an earthquake, it is joined to the pressure air valve 7.
非常事態が解消された後においては、水道管８の復旧を待って、前記圧力水槽１内の圧縮空気を排出し、圧力水槽１の上流側と下流側の緊急遮断弁９を開状態として圧力水槽１内に水を貯留し、同様に圧力空気槽２に空気圧縮機５により圧縮空気を充気し、次に備える。
After the emergency situation is resolved, the compressed water in the pressure water tank 1 is discharged after the water pipe 8 is restored, and the emergency shut-off
