Abstract
PURPOSE: To decrease troubles and prevent an automatic water supply tank from becoming incapable of being used, by mechanically supplying air to maintain the pressure in the tank without using electric means such as a solenoid valve etc.
CONSTITUTION: When water is drained from a pressure tank 1 through a pipe 11 and the water level falls below a minimum LWL, the float 8 of a stop valve 5 provided at the front end of an air supply pipe 4 located in the tank 1 descends. Thereby, a valve port 6 is opened to introduce air of predetermined pressure into the tank 1 through a pressure reducing valve 9. When the water level falls further to a lower limit LLWL, a pump 3 is operated according to a velel gauge signal to introduce water into the tank 1 to raise the water level to the minimum LWL. At that time, the air pressure in the tank 1 resing with the volume of the water is released to the outside through a relief valve 10.
