The D343H flanged three eccentric multi-level hard sealing butterfly valve
 Hard seal butterfly valve of the D343H-10/16/25 worm gear is widely used for medium temperature ≤ 425 ℃ metallurgy, electric power, petrochemical, as well as to the drainage and municipal construction, industrial pipe, of drying up the body to regulate the flow contained . Precision of the J-shaped elastic sealing ring and three eccentric and multi-level metal seal structure, the valve seat and disc sealing surface hardness and stainless steel has good corrosion resistance, long life, the valve has a two-way sealing function product meets the national the GB/T13927-92 valve pressure test standards.
【Features】
    A drive position (rotated 90 ° or 180 °) to install, easy to use. 2, the valve has a bi-directional sealing capabilities, installation not subject to the limitations of the medium flow, are not subject to the impact of spatial location and can be installed in any direction. 3, large format disc using the truss structure, high strength, flow area, flow resistance is small. 4 disc sealing surface surfacing cobalt based cemented carbide, sealing surface wear resistance, long service life. 5, the ring made ​​of stainless steel production, with a metal seal and elastic seal the dual advantages, both in the case of low and high temperature, with excellent sealing performance, corrosion resistant, long life characteristics. 6, the valve adopts three-eccentric sealing structure, seat and disc are almost no wear, the more the concept of more tight sealing function

三偏心特点及原理
1、偏离管道中心
2、偏离密封面中心
3、倾斜的锥形
当阀门开启时,蝶板与阀座在关闭时瞬间接触,利用蝶板偏心
1、偏心
2迅速脱离阀座,降低了密封副的磨损,磨擦力矩小,开启灵活。偏心锥面
3,使阀门在开启或关闭时蝶板能通过阀座内孔,实现接触密封。
另外,锥形蝶板的旋转半径大于密封副接触位置的旋转半径,故蝶板在阀门关闭时将出现越关越紧,能够实现自锁,防止蝶板过位。
