Abstract
The utility model discloses an electric valve control device which comprises an electric performer for controlling opening angles of a control valve mechanism. The electric performer is provided with an opening control port, a closing control port and a stop control port. A power supply branch of the opening control port is in series connection with a first switch unit and a first relay. A power supply branch of the closing control port is in series connection with a second switch unit and a second relay. A power supply branch of the stop control port is in series connection with a first normally-closed contact corresponding to the first relay and a second normally-closed contact corresponding to the second relay. As long as the opening control port or the closing control port is powered on, the power supply branch of the stop control port is cut off and a valve gate of an electric valve stays in a state of rotating forwardly or reversely. As long as the opening control port or the closing control port is powered off, the power supply branch of the stop control port is conducted and the valve gate of the electric valve stays in a stopped state. Therefore, the valve gate of the electric valve is easier and more accurate to control.
