Through internal components, the operating status of the electromagnetic pulse valve can be sensed, and the data can be transmitted to the cloud platform. Through the built-in program of the cloud platform, the operating status of the equipment can be analyzed.
The intelligent control valve of
intelligent valve driver usually adopts the following forms:
A. Pneumatic control valve with intelligent valve positioner;
B. Intelligent electric control valve; Pneumatic control valve with fieldbus intelligent valve positioner. Intelligent control function of intelligent valve driver mainly includes the following contents
A. Easily modify the flow characteristics of the control valve.
B. Realize PID control operation.
C. Realize other operation functions, such as range setting of split range control, nonlinear compensation operation, etc.
d. Change the positive and negative action mode of the control valve.
E. Realize communication with the host computer - realize information sharing. L realizes fault diagnosis and alarm of control valve.
G. Realize automatic locking of control valve.
H. Realize the status information management of control valve, etc. The advantages of using intelligent valve positioner are as follows.
A. Reduce the installation, calibration and
commissioning time of the control circuit.
B. Use the diagnostic function to make the control valve work. Longer service life, real-time monitoring of operating conditions.
C. Reduce the skill requirements for instrument maintenance personnel.
Pneumatic control valve with intelligent valve driver and
intelligent valve positioner The structure of this type of control valve is the same as that of ordinary control valve. Because of the intelligent valve positioner attached, the control valve has intelligent function and intelligent valve positioner
