　　品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……

　　(黄铜)内螺纹动态平衡电动调节阀应用于中央空调，供热采暖设备的液体流量，压力平衡自补偿及温度调节控制，空调系统如预冷空调箱（PAU）、空调箱（AHU）、新风机组（MAU）等末端设备或者采暖系统板换等末端设备retz(Brass) inlet internal thread Dynamic equilibrium electric control valve shallbe used for central air conditioning, liquid flow, pressure balance selfcompensation and temperature regulation control of heating equipment, andterminal equipment of air conditioning system such as pre cooling airconditioning box (PAU), air conditioning box (AHU), fresh air unit (MAU), orterminal equipment such as heating system board exchange

　　进口动态平衡电动调节阀技术参数 Technical paramete

　　内螺纹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 dynamicbalance electric control valve is divided into two parts: flow controlstructure 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 andregulation of the valve flow, and cooperate with the actuator to realize theelectric regulation and switching functions of the valve进口内螺纹动态平衡电动调节阀2.jpg

　　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 realizethe dynamic balance of the valve flow. The core components of the structure arethe pressure sensing membrane and the spring. The pressure sensing membranesenses the pressure (P1-P2) between the inlet of the valve and the inner cavityof the balance valve core. Under the effect of this pressure difference, theflow area of the variable flow channel is adjusted to keep the pressuredifference (P1-P2) basically constant, so as to keep the flow unchanged
