(法兰，对夹)进口气动中线软密封蝶阀适用于温度≤120℃或≤150℃，公称压力≤1.6MPa给排水、污水、食品、供暖、燃气、船舶、水电、冶金、能源系统以及轻纺等行业，特别适用于双向密封和阀体易锈蚀场合，作调节流量和截流介质(flange, wafer) imported pneumatic center line soft sealing butterfly valve is suitable for industries such as water supply and drainage, sewage, food, heating, gas, shipbuilding, hydropower, metallurgy, energy systems, and light textile with a temperature ≤ 120 ℃ or ≤ 150 ℃ and a nominal pressure ≤ 1.6MPa. It is particularly suitable for two-way sealing and valve body corrosion prone situations, as a flow regulation and interception medium

进口气动中线蝶阀产品详情 Product details

(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

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 POSTTTION

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

3、流量特性趋直线，调节性能好 Flow characteristics tend to be straight, with good regulation performance

4、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 The connection between the butterfly plate and the valve rod adopts a pin free structure, which overcomes possible internal leakage points

5、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 circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. The valve can be opened and closed under pressure for more than 50000 times without leakage

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

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