Abstract
The utility model relates to an electric adjusting valve, which belongs to the technical field of the valve control. The electric adjusting valve comprises a controller, a high-pressure-end pressure sensor, a low-pressure-end pressure sensor, an actuator and an adjusting butterfly valve, wherein the output end of the high-pressure-end pressure sensor is connected with a first input end of the controller, the output end of the low-pressure-end pressure sensor is connected with a second input end of the controller, the high-pressure-end pressure sensor is arranged in an inflow port of the adjusting butterfly valve, the low-pressure-end pressure sensor is arranged in an outflow port of the adjusting butterfly valve, the output end of the controller is connected with the input end of the actuator, and the output end of the actuator is connected with the input end of the adjusting butterfly valve. While the electric adjusting valve realizes the automatic adjustment, the electric adjusting valve can be applied to a variable-flow system with large variation of system load, and the stable working state can be maintained. The electric adjusting valve is simple in structure, strong in interference resistance and high in adjusting precision.
