Abstract

PURPOSE: To assure the supplementary air feeding operation of a water supply system by constituting same such that an air exhaust valve is provided at a position of a pressure tank at a desired lower limit water level and a supplementary feed air tank and other valves and pipes are provided below the lower limit water level of the pressure tank.
CONSTITUTION: A level of water in a pressure tank 1 is held above a lower limit water level LWL by the action of an automatic air exhaust valve 5. If a magnet valve 10 closes and another magnet valve 12 opens, water in a supplementary feed air tank 6 flows out therefrom through a drain pipe 11. Simultaneously, air is taken into the supplementary feed air tank 6 through an air intake valve 13. On the contrary, if the magnet valve 12 closes and the magnet valve 10, water in the pressure tank 1 flows out therefrom into the supplementary feed air tank 6 through a feed pipe 9. Air in the supplementary feed air tank 6 is pushed up by the water having flowed into the tank 6 to be supplementarily fed into the pressure tank 1 through a supplementary feed air pipe 7 and a check valve 8.
