PNEUMATIC LIQUID TRANSFER SYSTEM

摘要

The pneumatic liquid transfer system transfers liquid using a pneumatic circuit composed of an air pressure regulator (6), a needle valve (7), an air charging room (8), a pressure controller (10), a solenoid valve (11) and an air on-off valve. If the pressure of the compressed air filled in the air charging room is equal to the pressure designated in the pressure controller, a pneumatic rotary cylinder valve (5) is closed by the 5/2-way solenoid valve while the on-off air spring valve is opened and the air in the air charging room is issued out so that the pressure of a vacuum room (2) decrease. Thereby the liquid in the tank 1 is transferred to the tank 2.
