Automatic control device of choke manifold

The invention relates to an automatic control device of a choke manifold. The control device comprises a sensor assembly, a display control assembly, and an execution assembly. The execution assembly comprises a proportional throttle valve, a magnetic exchange valve, a motor, a hydraulic pump, a combined valve block, and an energy accumulator. The input end of the display control assembly is connected with the sensor assembly, and the output end is connected with the proportional throttle valve, the magnetic exchange valve, and the motor. The motor is connected with the combined valve block through the hydraulic pump. The combined valve block is connected with the energy accumulator. The energy accumulator is connected with the choke manifold through the proportional throttle valve and the magnetic exchange valve in sequence. The display control assembly controls operation of the magnetic exchange valve, the proportional throttle valve, and the motor according to the data acquired by the sensor assembly, so a
