進口電動調節閥 技術參數 Technical paramete

電動調節閥應用在暖通空調系統中，在能量的輸配和維持水循環系統的水力平衡方面起到非常重要的作用。主要配合末端執行機構，從控制系統接收控制信號和調節閥桿的信號值，而執行器則根據信號值調節閥門開度，改變管網系統的流量  Electric control valve is used in HVAC system, which plays a very important role in energy transmission and distribution and maintaining the hydraulic balance of water circulation system. It mainly cooperates with the end effector to receive the control signal 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 to change the flow of the pipe network system

安裝說明 Installation instructions

1.注意閥門介質流向應與管路介質流向一致  Note: the flow direction of valve medium shall be consistent with that of pipeline medium

2.閥門可以安裝在供水或回水管路上，一般推薦安裝在回水管路上（安裝在回水管路上可以使水流控制更為平穩，同時熱水回水部分的溫度較低，可延長閥門使用壽命），同時推薦在閥門前安裝過濾器和止回閥。當介質為蒸汽時，管道上安裝排水閥，可以除去凝結水，否則將影響閥門使用壽命  The valve can be installed on the water supply or return pipeline. It is generally recommended to install it on the return pipeline (the installation on the return pipeline can make the water flow control more stable, and the temperature of the hot water return part is low, which can prolong the service life of the valve). At the same time, it is recommended to install a filter and a check valve in front of the valve. When the medium is steam, a drain valve is installed on the pipeline to remove the condensed water, otherwise the service life of the valve will be affected

3.注意閥門安裝方向 Pay attention to the installation direction of the valve

介質為蒸汽時，可以任意角度安裝介質為冷/熱水時，不能向下安裝 When the medium is steam, it can be installed at any angle; when the medium is cold / hot water, it cannot be installed downward
