德國《LOCKE》洛克進(jìn)口比例積分電動調(diào)節(jié)閥QS系列閥門驅(qū)動器為內(nèi)置24V/AC雙向可逆馬達(dá)直行程驅(qū)動器，能接受與反饋0-10V或4-20mA控制訊號，與KT/KTF系列閥體配套使用提供比例式控制，實現(xiàn)管道中介質(zhì)流量的調(diào)節(jié)功能。廣泛應(yīng)用于空調(diào)、采暖等系統(tǒng)中，亦可通過不同的連接器與其它閥門配套使用。驅(qū)動器垂直安裝于閥體上，不可安裝在閥體下面，需留出足夠的空間以便日常維護(hù)。

The QS series valve driver of proportional integral electric control valve imported from Germany "locke" is a built-in 24 V / AC bidirectional reversible motor direct stroke driver, which can receive and feedback 0-10V or 4-20mA control signal. It is used with kt / KTF series valve body to provide proportional control and realize the regulation function of pipeline medium flow. It is widely used in air conditioning, heating and other systems. It can also be used with other valves through different connectors. The actuator should be installed vertically on the valve body, not under the valve body. Enough space should be reserved for routine maintenance.

三、進(jìn)口比例積分電動調(diào)節(jié)閥工作原理：

電動比例調(diào)節(jié)閥在控制形式上是通過閥門開啟角度大小來實現(xiàn)控制開度和截面面積?？刂七^程是在電機轉(zhuǎn)動過程中，不斷以線性電阻值反饋給控制單元，控制單元根據(jù)測量值和電動調(diào)節(jié)閥的反饋電阻值進(jìn)行比對和判斷，發(fā)出控制信號到達(dá)目標(biāo)位置即刻停止動作的原理。

Electric proportional control valve in the control form is through the valve opening angle to control the opening and cross-sectional area. The control process is that in the process of motor rotation, the linear resistance value is continuously fed back to the control unit. The control unit compares and judges the measured value with 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.
