Abstract
PURPOSE: To avoid the pressure change accompanied with the air venting operation with a pressure detector, by automatic air venting operation in a suitable time interval according to the amount of air in an air tank.
CONSTITUTION: At normal discrimination where the water level in an air tank 12 is a given lower limit value, the air flowing to the direction of the 1st water supply pipe 14 from a supply water main pipe 10 does not go to the direction of a pressure detector 30, but is fed to the direction of an air tank 12 and stored in the air tank 12, since the 2nd water supply pipe 32 is bent downward in crank shape. When the air in the tank 12 increases, the water level in the tank 12 is decreased and is less than a given lower limit, then it is detected at a water level detector 60, and after the 2nd electromagnetic switcing valve 36 is closed, the 1st electromagnetic switching valve 24 is open, the air vent is started by the 1st exhaust water pipe 20. In this case, since the 2nd electromagnetic switching valve is closed in a pressure detector 30, the pressure change due to the air vent can not be delivered.
