Vacuum pressure regulating system

The invention discloses a vacuum pressure regulating system. The vacuum pressure regulating system comprises a controller, a vacuum valve, a pressure sensor, potentiometers, a motor and a control panel. The controller is in communication with the pressure sensor through the vacuum valve. The motor is connected with the vacuum valve. The pressure sensor is in communication with the potentiometers. The control panel is connected with the controller. By means of the mode, according to the vacuum pressure regulating system, the vacuum valve is rapidly and automatically regulated in the whole process, accuracy is high, and meanwhile the vacuum pressure regulating system is economical and practical due to the fact that the motor serves as a power source. The whole valve is compact in structure, small in size and suitable for wide popularization.
