  • Method And Apparatus For Determining Parameter Relationship Of Control Valve
    Publication number: 20250377670
    Abstract: Various embodiments of the teachings herein include a method for determining a parameter relationship of a pressure independent control valve. An example includes: determining an actual value of a mechanical structure parameter and an actual value of a controlled pressure difference parameter of the pressure independent control valve; entering the actual value of the mechanical structure parameter and the actual value of the controlled pressure difference parameter into a calibration model adapted to determine a correlation between a flow rate parameter and a pressure difference parameter of the pressure independent control valve on the basis of the mechanical structure parameter and the controlled pressure difference parameter; and receiving the correlation between the flow rate parameter and the pressure difference parameter from the calibration model.
