EMERGENCY WATER STORAGE TANK
To provide an emergency water storage tank that is installed in the middle of a water service pipe or other fresh water supply pipes, that normally supplies fresh water through the water storage tank, and that allows water stored in the water storage tank to be used in a case of emergency such as water failure, wherein a conventional water storage tank has a problem that stagnation in a tank may increase when there is a temperature difference between the water stored in the tank (old water) and the water supplied to the tank (new water), and means of the solution to the problem is provided on how to avoid increase in the stagnation.SOLUTION: The emergency water storage tank comprises a sub-inflow pipe 23 that guides a part of water flowing into a water tank body 1 from inflow pipeline 2 connected to an inflow pipe 21 to an upstream end part of an in-tank flow of a bottom at the bottom of the water storage tank body 1. Preferably, the emergency water storage tank further comprises a sub-outflow pipe 33 for sucking the part of the water flowing out of the water tank body 1 to an outflow pipe 3 connected to outflow piping 31 from a downstream end part of the in-tank flow of the bottom at the bottom of the water storage tank.SELECTED DRAWING: Figure 1
【課題】水道管その他の清水の給水管の途中に設けられ、通常時は当該貯水槽を経由して清水を給水し、断水などの非常時には貯水槽に蓄えられた水を使用できるようにした貯水槽に関し、槽内に貯留されている水（旧水）と槽内に供給される水（新水）に温度差がある場合に、槽内の滞留が増加するおそれがあるとすれば、その滞留の増加をどのようにして避けることができるか、という課題の提起とその解決手段を提供する。【解決手段】流入配管２１に接続した流入管２から貯水槽本体１に流入する水の一部を貯水槽本体１の底部の当該底部における槽内流れの上流端部分に導く副流入管２３を備えている。好ましくは更に、貯水槽本体１から流出配管３１に接続した流出管３に流出する水の一部を貯水槽底部の当該底部における槽内流れの下流端部分から吸入する副流出管３３を備えている。【選択図】図１
