进口动态平衡电动调节阀 技术参数 Technical paramete

动态平衡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

动态平衡电动调节阀安装说明 Installation instructions

1.安装前请详细阅读说明书，检查产品型号和参数，根据要求设定工作电压和输入信号 Before installation, please read the instructions carefully, check the product model and parameters, and set the working voltage and input signal as required

2.尽可能保证垂直安装，预留空间以方便维护 Vertical installation shall be ensured as much as possible, and space shall be reserved for convenient maintenance

3.安装时应注意保证水流方向与阀体上箭头所指方向一致 During installation, pay attention to ensure that the water flow direction is consistent with the direction indicated by the arrow on the valve body

4.建议设计系统旁路连通，灌装时应该由旁路将管路中杂质冲洗干净，否则可能会引起阀门堵塞 It is recommended to design the bypass connection of the system. During filling, the impurities in the pipeline should be flushed by the bypass, otherwise the valve may be blocked

5.安装时应保证阀门前后预留一定长度的直管段，一般在进口预留管道直径10倍长度的直管段，出口预留管道直径5倍长度的直管段  During installation, a certain length of straight pipe section shall be reserved before and after the valve. Generally, a straight pipe section 10 times the length of the pipe diameter shall be reserved at the inlet and a straight pipe section 5 times the length of the pipe diameter shall be reserved at the outlet
