(黃銅)進口內螺紋電動調節閥 技術參數 Technical paramete
(黃銅)進口內螺紋電動調節閥結構分為流量調節結構和動態平衡結構兩部分 RETZ structure of dynamic balance electric control valve is divided into two parts: flow control structure and dynamic balance structure
流量調節結構可完成閥門流量的設定和調節,配合執行器可實現閥門的電動調節、開關功能 RETZ flow regulating structure can complete the setting and regulation of the valve flow, and cooperate with the actuator to realize the electric regulation and switching functions of the valve
動態平衡結構可實現閥門流量的動態平衡,該結構的核心部件為感壓膜片和彈簧,感壓膜片感應閥門入口和平衡閥芯內腔之間的壓(P1-P2),在此壓差作用下調節可變流道的流通面積,保持壓差(P1-P2)基本恒定,從而保持流量不變 RETZ dynamic balance structure can realize the dynamic balance of the valve flow. The core components of the structure are the pressure sensing membrane and the spring. The pressure sensing membrane senses the pressure (P1-P2) between the inlet of the valve and the inner cavity of the balance valve core. Under the effect of this pressure difference, the flow area of the variable flow channel is adjusted to keep the pressure difference (P1-P2) basically constant, so as to keep the flow unchanged
結構特性:二通/三通分流/三通合流 Structure: two-way / three-way diversion / three-way confluence

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
