　　电动调节阀应用在暖通空调系统中，在能量的输配和维持水循环系统的水力平衡方面起到非常重要的作用。主要配合末端执行机构，从控制系统接收控制信号和调节阀杆的信号值，而执行器则根据信号值调节阀门开度，改变管网系统的流量 Electric control valve isused in HVAC system, which plays a very important role in energy transmissionand distribution and maintaining the hydraulic balance of water circulationsystem. It mainly cooperates with the end effector to receive the controlsignal from the control system and adjust the signal value of the valve rod,while the actuator adjusts the valve opening according to the signal value tochange the flow of the pipe network system

　　安装说明 Installationinstructions

　　1.注意阀门介质流向应与管路介质流向一致 Note: the flow direction ofvalve medium shall be consistent with that of pipeline medium

　　2.阀门可以安装在供水或回水管路上，一般推荐安装在回水管路上（安装在回水管路上可以使水流控制更为平稳，同时热水回水部分的温度较低，可延长阀门使用寿命），同时推荐在阀门前安装过滤器和止回阀。当介质为蒸汽时，管道上安装排水阀，可以除去凝结水，否则将影响阀门使用寿命 The valve can be installedon the water supply or return pipeline. It is generally recommended to installit on the return pipeline (the installation on the return pipeline can make thewater flow control more stable, and the temperature of the hot water returnpart is low, which can prolong the service life of the valve). At the sametime, it is recommended to install a filter and a check valve in front of thevalve. When the medium is steam, a drain valve is installed on the pipeline toremove the condensed water, otherwise the service life of the valve will beaffected

　　3.注意阀门安装方向 Pay attention to the installation direction of the valve
