[0002] In the automatic control of modern production, regulating valves play a very important role. Production depends on the correct distribution and control of the flowing medium, which includes energy exchange, pressure reduction and simple container charging. Regulating valves, also known as control valves, are the final control elements in the field of industrial automation process control that change the process parameters such as medium flow, pressure, temperature, and liquid level by adjusting the control signal output by the control unit and using power operation. Regulating valves generally include regulating mechanisms and actuators. The actuators play a driving role, and the regulating mechanisms play a role in regulating flow. Under the impetus of the actuators, the flow area between the valve core and the valve seat is changed by changing the valve core stroke in the regulating mechanism, thereby changing the resistance coefficient to achieve the purpose of regulating flow.
