What is the function of intelligent electric control pneumatic valve?

　 （ ） PI adjustment when intelligent adjustment pneumatic valve to accept transducer signal which can adjust the PI, microcomputer first compares the transducer signal with a given signal, and according to the preset law of PI parameters calculation, then send control signal to the actuator, and adjust, pneumatic valve until signal balance.
smart electric adjust the PI regulating function of pneumatic valve, is a low cost and good performance of sampling control system, and don't need to use the conventional PID controller, and directly to the transducer signal, complete analog continuous control system is difficult to work. Some industrial object lag time is very long, Such as control stove temperature) , this will cause big, slow, error of the system using a microcomputer sampling and to control, can improve the control performance of low pass.
　　（ ） Fixed flow characteristic when intelligent adjusting flow curve correction, pneumatic valve, servo amplifier in the microcomputer, according to the preset parameters to signal is calculated, the input signal and the displacement of the pneumatic valve to achieve the required digital function relation, and nonlinear adjustments, this makes the choice of flow characteristics and is simple and easy to change, it is very important for control system. Using the pneumatic valve core to change shape or change the shape of CAM to change the flow characteristic of method appears behind. And angular travel like butterfly pneumatic valve, pneumatic valve, can't change the shape of the pneumatic valve core way to change the flow characteristic. Intelligent type actuator with can completely change the situation, because it is the intelligent type pneumatic valve adjustment.
can realize the flow characteristic of changes include: equal percentage - The standard linear; The standard linear - Equal percentage; Quick opening - The standard linear; Quick opening - Equal percentage; Parabolic - The standard linear; Parabolic - Percentage, etc.
　　（ ） Other functions such as, the change of reaction way, the fault position indicator, diagnosis and alarm, electric braking, self-locking, etc.
