なしブースタ式給水装置がある。In general, equipment for supplying water to specified locations in high-rise buildings includes:
For example, water is primarily stored in a water tank using a lead-in pipe from the water main, and then a water pump is used to send water to an elevated tank installed at a height that provides the necessary pressure for the highest water fountain or appliance in the building. A so-called elevated tank type water supply device pumps up water and supplies water from this elevated tank to a predetermined location within the structure by gravity, and the water in the water receiving tank is sent into a pressure tank by a water supply pump, and the air in the pressure tank is pumped into a compressor. There is a so-called pressure tank type water supply system that compresses the water in the tank and pumps it to a predetermined location on the structure, and a so-called tankless booster type water supply system that supplies the water in the water receiving tank to a predetermined location on the structure using only a water supply pump. There is.

10 C and is discharged into the atmosphere, and the inside of this tank 4 becomes negative pressure.
したがって、高置タンク１６への揚水が停止されると同
時に、圧力タンク４内に注入管１４を介して受水槽１内

万一圧力タンク４内の圧力が許容限度以上に高められた
としても、この圧力タンク４の爆発等の危険を最小限に
とどめることができ、安全性が高い。Moreover, since the pressure tank 4 was submerged in the water tank 1,
Even if the pressure inside the pressure tank 4 were to rise above the permissible limit, the danger of explosion of the pressure tank 4 can be minimized, resulting in high safety.
さらに、受水槽１内への水の補給もボールタップ３によ
