Abstract
PURPOSE: To prevent the generation of a water-hammer phenomenon, by opening an intake valve after closing an exhaust valve and a check valve for liquid admission when moving to a liquid discharge process from a liquid admission process.
CONSTITUTION: When a liquid level in a tank 1 reaches an upper limit, a contact b of a level switch 71 is opened, and a contact a is closed in place of the contact b. Thus, a solenoid 32 is demagnetized, an exhaust valve 3 is closed and conduction to a timer 72 is simultaneously started. After starting conduction to the timer 72, a check valve 4 is closed, and a timer 73 is closed, thus exciting a solenoid 22, then opening an intake valve 2. Compressed air is introduced into the tank 1 when opening the valve 2, and liquid in the tank 1 is discharged from a check valve 5 for discharging liquid by the increase of atmospheric pressure in the tank.
