Abstract
PURPOSE: To assure the supplementary air feeding operations of a water supply system by constituting same such that a supplementary feed air tank is provided below a predetermined lower limit level of water in a pressure tank and the system is provided with an auxiliary air tank.
CONSTITUTION: A magnet valve 7 opens during running of a pump 2 whereas another magnet valve 9 opens during stop of the pump 2. Accordingly, if the pump 2 is stopped, then water in a supplementary feed air tank 4 is exhausted therefrom and the atmospheric air is admitted into the tank 4 through a valve 11. If pressure in the pressure tank 1 is decreased to a lower limit pressure P1 due to demand for water, then a pressure switch 12 operates to initiate the operation of the pump 2. Since, if the amount of air in the pressure tank 1 is less than an appropriate level, an auxiliary air tank 13 is filled with water, water in the pressure tank 1 flows out therefrom, by running of the pump 2, into the supplementary feed air tank 4, and air in the supplementary feed air tank 4 is sent into the pressure tank 1 instead. When the pressure in the pressure tank 1 reaches an upper limit pressure P2, the pump 2 is stopped. Thus, supplementary air feeding operations will continue until the appropriate amount of air is reached in the pressure tank 1.
