Electric actuator is the valve to open, close or adjust the control of the drive equipment. The utility model relates to a device which is suitable for controlling and regulating various butterfly valves and ball valves in open-loop or closed-loop control systems. The utility model has the advantages of full function, reliable performance, advanced control system, small volume, light weight, convenient operation and maintenance, etc. . The valve can be remote control, centralized control and automatic control. Widely used in electric power, metallurgy, petroleum, chemical, paper, sewage treatment and other industries.
The Integral electric actuator valve comes with a control box, known as a mechatronics engineering. With LCD display, can feedback 4 ~ 20mA standard signal, can determine the valve full open, full closed, and uncertain intermediate position, that is, switch volume control. The electrical element is mounted on a reversible plate to adjust the torque control mechanism, stroke control mechanism and opening indication mechanism.
Integral electric actuator valve integral module debugging method: Manually put the electric device in the middle position; connect AC380 power supply, the power indicator light; if the power supply is out of phase, it will be out of phase indicator light; position feedback signal adjustment during conventional control. Turn the motor to full off position, adjust the voltage of the two test points to close to zero (≤2MV) , then adjust the voltage of the motor to 4 ma. Turn the motor to full open position The output signal is 20mA by adjusting the 20mA potentiometer. The above adjustment can be completed only once. Note: If the potentiometer is rotated clockwise, the output signal will be decreased. If the potentiometer is rotated clockwise, the lines on both sides of the potentiometer should be interchanged. If the potentiometer is rotated clockwise, the output signal of the potentiometer will be decreased.
The controller is composed of phase sequence self-adapting, phase absence protection function module, operation control function board, film panel component and AC contactor It has the functions of on-site and remote operation key switch control, fault alarm passive contact output, and valve position signal 4~20mA output, etc. Suitable for all kinds of valves in open-loop control system to operate and control.
