(黄铜)进口内螺纹电动调节阀 技术参数 Technical paramete

(黄铜)进口内螺纹电动调节阀结构分为流量调节结构和动态平衡结构两部分  RETZ structure of dynamic balance electric control valve is divided into two parts: flow control structure and dynamic balance structure

流量调节结构可完成阀门流量的设定和调节，配合执行器可实现阀门的电动调节、开关功能 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

动态平衡结构可实现阀门流量的动态平衡，该结构的核心部件为感压膜片和弹簧，感压膜片感应阀门入口和平衡阀芯内腔之间的压（P1-P2），在此压差作用下调节可变流道的流通面积，保持压差（P1-P2）基本恒定，从而保持流量不变  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

安装说明 Installation instructions

1.注意阀门介质流向应与管路介质流向一致  Note: the flow direction of valve 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 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.注意阀门安装方向 Pay attention to the installation direction of the valve

介质为蒸汽时，可以任意角度安装介质为冷/热水时，不能向下安装 When the medium is steam, it can be installed at any angle; when the medium is cold / hot water, it cannot be installed downward
