description The utility model provides a device is stopped to automatic opening of no bottom valve centrifugal water pump, it is at a pool high level sensor of installation and a low level sensor, installs the solenoid valve between pipeline and jet pump, installs the solenoid valve between the jet pump and the centrifugal pump pump body, and electric contact pressure gauge is installed to installation electric contact vacuum pressure table on the centrifugal pump body between the inlet tube and the centrifugal pump body, and when positive surge to high level sensor position, the solenoid valve is opened, and the centrifugal pump motor starts the operation, when water pipe pipeline internal pressure value reaches a definite value, the electric contact pressure gauge action, the solenoid valve outage is closed, when decline of water table to low level sensor position, the water pump stop work.
