四、進(jìn)口比例積分電動(dòng)調(diào)節(jié)閥工作原理：

電動(dòng)比例調(diào)節(jié)閥在控制形式上是通過(guò)閥門(mén)開(kāi)啟角度大小來(lái)實(shí)現(xiàn)控制開(kāi)度和截面面積?？刂七^(guò)程是在電機(jī)轉(zhuǎn)動(dòng)過(guò)程中，不斷以線(xiàn)性電阻值反饋給控制單元，控制單元根據(jù)測(cè)量值和電動(dòng)調(diào)節(jié)閥的反饋電阻值進(jìn)行比對(duì)和判斷，發(fā)出控制信號(hào)到達(dá)目標(biāo)位置即刻停止動(dòng)作的原理。

四、 Working principle of imported proportional integral electric regulating valve:
The electric proportional control valve is used to control the opening and cross-section area by the opening angle of the valve. The control process is the principle of continuously feedback the linear resistance value to the control unit during the motor rotation. The control unit compares and judges the measured value and the feedback resistance value of the electric control valve, and sends out the control signal to stop the action immediately when it reaches the target position.
