Intelligent electric control pneumatic valve actuator the pneumatic valve control precision is improved

Electric adjustment by the electric pneumatic valve adjustment pneumatic valve actuator and regulating pneumatic valve assembly, electric control pneumatic valve actuator is control of the pneumatic valve is the main part of the adjustment. To differentiate from the aspects of function, adjust electric pneumatic valve actuator is mainly divided into normal and intelligent, here mainly to analyze the smart electric regulation structure and working principle of pneumatic valve actuator.





the traditional electric regulating pneumatic valve actuator is relatively simple, using the servo amplifier and actuator can complete the function of the basic design, but intelligent electric regulating pneumatic valve actuator to complete the human-computer interaction, intelligent control, communication and so on some relatively complex functions, this request in the traditional electric control on the basis of the pneumatic valve actuator increase some new modules to support these functions.


smart electric adjustment, the basic function of the pneumatic valve actuator module is mainly composed of main control unit, interface module, power module, power drive module, servo drive control module, feedback module. Intelligent electric control pneumatic valve actuator control unit through CAN bus transmission and PC commands to control object, Such as pneumatic valves) Detection sensor feedback signal, on the basis of calculating the required master CPU speed control signal, and then the signal transmitted in any suit drive control module, power drive module drive motor rotation, make the controlled object, Pneumatic valve) The opening in the ideal time to achieve a reasonable position. Intelligent electric control pneumatic valve actuator using the field bus communication technology will be closely linked to the servo amplifier and power driver module, realize the main control unit and the actuator of two-way communication, on-line calibration, self diagnosis and protection function, greatly improve the control precision and the safety of the equipment operation.





intelligent electric control pneumatic valve by its simple structure, convenient operation, choose a wider temperature range, fast response time, good sealing performance, and can be adjusted while in a run, therefore widely used in chemical, petroleum, food, textile, such as hotels and restaurants sector hot water supply.
