进口内螺纹电动调节阀 黄铜电动调节座阀 美国RETZ瑞茨

　　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……

　　进口内螺纹电动调节阀由1200N电动执行器与黄铜调节阀体组合而成的系列电动调节阀，广泛应用于空调、制冷、采暖以及楼宇自动控制系统中，可准确调节系统中的介质流量，从而达到控制温度、湿度、压力和节能的目的retz The imported internal thread electric regulating valve is aseries of electric regulating valves composed of a 1200N electric actuator anda brass regulating valve body. It is widely used in air conditioning,refrigeration, heating, and building automatic control systems. It canaccurately adjust the medium flow rate in the system, thereby achieving thegoal of controlling temperature, humidity, pressure, and energy conservation

　　(黄铜)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 dividedinto two parts: flow control structure and dynamic balance structure进口内螺纹电动调节阀2.jpg

　　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

　　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

　　进口内螺纹电动调节阀性能特点∶ Performance characteristics

　　阀体采用阀体无底盖设计，阀杆采用带润滑4层密封保护，使用寿命比普通阀门更长 The valve body is designedwith no bottom cover, and the valve stem is protected by 4-layer sealing withlubrication. The service life is longer than that of ordinary valves

　　驱动器采用全套钢质传动齿轮。同步马达和二个限位浮动式辅助开关具有到位断电功能，实现了对马达的保护和节能作用，控制精度更高，响应速度快，无噪音，使用寿命比普通驱动器更长 RETZ driver adopts a fullset of steel transmission gears. The synchronous motor and two limit floatingauxiliary switches have the power-off function in place, which realizes theprotection and energy-saving function of the motor. The control precision ishigher, the response speed is faster, the noise is free, and the service lifeis longer than that of the ordinary driver

　　驱动器配有手动调节功能，阀门和驱动器连接采用紧顶螺丝，阀杆卡板连接，方便快速易连接，便于现场安装和调试 The driver is equipped withmanual adjustment function. The connection between the valve and the driver ismade with set screws and the valve stem clamp plate, which is convenient forquick and easy connection and convenient for on-site installation andcommissioning
