Abstract
PURPOSE:To make operation smooth by providing an introduced pressure ON.OFF valve for a pressure lead pipe which connects a delivery pipe to a control unit of a coupling and by installing a three-way valve, which shifts the introduced pressure to a high pressure source or the air, to a branch pipe diverged from a pressure lead pipe located between the three way valve and the control unit. CONSTITUTION:An introduced pressure ON.OFF valve 7 is installed in a pressure lead pipe 6 which connects a delivery pipe 5 of a centrifugal pump 1 to a control unit 4 of a coupling. A branch pipe 8 is diverged from a pressure lead pipe 6 located between the introduced pressure ON.OFF valve 7 and the control unit 4. In the branch pipe 8 is installed a three-way valve 9 which shifts the introduced pressure to a connecting pipe 10 to a high pressure source or an air vent pipe 11. Thus, shift of the introduced pressure ON.OFF valve 7 and the three-way valve 9 can convert the pressures introduced into the control unit of the coupling and control the rotary speed of the pump 1. Therefore, the rotary speed of the pump 1 can be controlled to meet the operating requirements and smooth operation can be provided.
