Actuating Mechanism, Control Valve And Valve Control System

A control valve of a valve control system, the valve control system comprising a control center capable of sending a control signal and of receiving a diagnostic signal and subjecting the diagnostic signal to analytical diagnosis, the control valve comprising:

• a valve having a valve rod;
• and
• an actuating mechanism comprising:
• a drive unit capable of receiving the control signal and, on the basis of the control signal, driving the valve rod in an axial direction or rotating around the axial direction;
• a sensor unit disposed at the drive unit, the sensor unit capable of detecting a driving force applied to the valve rod when the drive unit moves the valve rod and generating a driving force signal containing driving force data;
• a data processing unit capable of receiving the driving force signal and conditioning the driving force signal, and then generating the diagnostic signal;
• and
• a communication control unit capable of receiving the control signal sent by the control center and sending the control signal to the drive unit, the communication control unit also capable of receiving the diagnostic signal and sending the diagnostic signal to the control center.
