进口电动对夹式蝶阀 中线 软密封电动蝶阀 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……进口电动对夹式蝶阀电动执行器采用一体化结构，接入220VAC电源即可控制运转，也可加入控制模块,输入控制信号（4-20mADC或1-5VDC）进行调节控制

　　retzThe imported electric neutral soft sealing butterfly valve (clamp, flange)adopts an integrated structure, and the electric actuator can be controlled tooperate by connecting to a 220VAC power supply. Control modules can also beadded to input control signals (4-20mADC or 1-5VDC) for adjustment and control

　　功能介绍Function introduction

　　进口电动对夹式蝶阀采用中线弹性橡胶密封，弹性阀座配高精度蝶板确保零泄漏，阀杆底、中、上部配有衬套，用于支撑和旋转滑动，保特最小磨擦力 Theimported electric center line soft seal butterfly valve (wafer, flange) adoptsthe center line elastic rubber seal, the elastic valve seat is equipped withhigh-precision butterfly plate to ensure zero leakage, and the bottom, middleand upper parts of the valve rod are equipped with bushings for support androtary sliding, and the minimum friction force is guaranteed

　　进口电动对夹式蝶阀设计特色 Design features

　　1、蝶板的回转中心(即阀杆的中心)位于阀体的中心线和蝶板的密封面截面上 Therotating center of the butterfly plate (i.e. the center of the valve stem) islocated on the center line of the valve body and the section of the sealingsurface of the butterfly plate

　　2、小巧轻便，容易拆装及维修，操作扭矩小，90°回转开启迅速，并可在任意位置安装 Smalland light, easy to disassemble and repair, small operating torque, 90 °rotation and quick opening, and can be installed at any position

　　3、流量特性趋直线，调节性能好。蝶板与阀杆的连接采用无销钉结构，克服了有可能的内泄漏点 Theflow characteristics tend to be straight, and the regulation performance isgood. The connection between the butterfly plate and the valve rod adopts apinless structure, which overcomes possible internal leakage points

　　4、蝶板外圆采用球面造型，提高了密封性能及延长了阀门的使用寿命，带压启闭5万次以上仍保持零泄漏 The outer circleof the butterfly plate adopts spherical shape, which improves the sealingperformance and prolongs the service life of the valve, and keeps zero leakageafter opening and closing under pressure for more than 50000 times

　　5、密封件可更换，且密封可靠达到双向密封 Thesealing element can be replaced, and the sealing is reliable to achieve two-waysealing

　　6、蝶板可根据用户要求喷涂覆层，如尼龙或聚四氟类 Thebutterfly plate can be coated according to user requirements, such as nylon orPTFE

　　7、可设计成法兰连接和对夹连接 Can be designedas flange connection and wafer connection
