The angle range of a high-platform ball valve can be accurately and automatically adjusted according to the gas consumption of a client site to control the water spraying amount. Meanwhile, the water cut-off valve for the water-spraying oil-free compressor can achieve accurate adjustment of the water spraying amount by 0-100% and is higher in safety and reliability. The device comprises a servo motor, a high-platform ball valve, a motor speed reducer and a valve core, an output shaft of the servo motor is connected with the motor speed reducer, and the motor speed reducer is connected with the valve core; the valve element is installed in the high platform ball valve and used for controlling the opening angle of the high platform ball valve. The control signal input end of the servo motor is connected with a PLC, the PLC is connected with two temperature sensors, one of the two temperature sensors is used for detecting the water spraying temperature of a main machine of the compressor, and the other one of th
