(法兰，对夹)气动中线软密封蝶阀

(法兰，对夹)进口气动中线软密封蝶阀是以压缩空气0.4-0.7MPa的气源为动力，驱动阀杆带动带碟板在阀体内做0-90度的旋转，达到对蝶阀全开和全关的操作控制 RETZ (Flange, wafer) The inlet pneumatic midline soft seal butterfly valve is powered by 0.4-0.7MPa compressed air, which drives the valve stem to drive the disc plate to rotate 0-90 degrees in the valve body, so as to achieve full opening and full closing operation control of the butterfly valve

(法兰，对夹)进口气动中线软密封蝶阀 结构特点 Structural characteristics

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。阀座采用合成橡胶。关闭时蝶板的外圆密封面挤压合成橡胶阀座，使阀座产生弹性变形而形成弹性力作为密封比压保证蝶阀的密封 retz品牌The rotary center of the butterfly plate (i.e. the center of the valve stem) is located on the centerline of the valve body and the sealing surface section of the butterfly plate. The valve seat is made of synthetic rubber. When closing, the outer sealing surface of the butterfly plate squeezes the synthetic rubber valve seat, which causes the elastic deformation of the valve seat and forms the elastic force as the sealing specific pressure to ensure the sealing of the butterfly valve

1、小巧轻便，容易拆装及维修，并可在任意位置安装 Small and light, easy to disassemble and repair, and can be installed at any position

2、结构简单、紧凑，操作扭矩小，90°回转开启迅速 Simple and compact structure, small operating torque, quick 90 ° rotation and opening
