結構形式/Structure
彈性密封結構是一種金屬對金屬彈性硬密封結構，是將裝在閥座上的一種結構形式。U形環用壓板壓住，并用螺栓固定，U形環的兩面分別有密封性能很好且耐高溫、高壓的密封圈，并有一定的余量，可以通過調節U形環的位置，使得閥門在使用一段時間后不因磨損而泄漏。該閥門適用中、高溫及中、高壓管路系統。
Seal flexible structure is a hard flexible metal on metal seal structure will be installed in the valve seat is on a structure .U-shaped ring with clipsand fixed with bolts ,U-ring seals on both sides were very good performance and high temperatures ,high pressure of the ring and have a certain cushion ,you can adjust the location of U-rings ,making valve In the use of the door after a period of time due to wear and do not leak .The application of the valve ,and high- temperature ,high-pressure pipeline system.
三偏心結構是在設計時將閥桿偏離密封面中心線，形成第一個偏心；閥桿略偏離管路中心線，形成第二個偏心；閥板密封面加工成圓錐體的一個斜截體，形成第三個偏心。三個偏心的結構使閥門密封副在啟閉過程中盡可能小地減少磨擦，在閥板開始旋轉的瞬間密封面完全脫離，從而實現了無磨擦密封。這種結構是蝶閥的一次質的飛躍，閥門因此大大地提高了使用壽命，并使啟閉扭矩的大小有了明顯地改善。
Three eccentric structure is in the design will stem from the centerline sealing surface ,forming the first eccentric ;stem pipe slightly deviated from the centerline ,a second ecc-entric ;disc sealing surface processed into the cone of a cut-off ramps ,A third eccentric .Three eccentric use of the structure of the valve seal in the course of the hoist as small as possible to reduce friction in the valve plate starting rotation of the moment completely sealed from the surface ,thus achieving a sealed without friction .This structure is a butterfly valve qualitative leap, valves therefore greatly enhance the life, and hoist the size of torque has been noticeably improved.
在軸與體相對運動的關鍵部分采用高耐磨型自潤滑復合軸承，減小蝶板在開啟或關閉時的磨擦力，保證軸和體的永無磨損。
Axis and the relative movement of a key part of a high wear-resistant type of self-lubricating bearings ,reducing the butterfly plate in the open or closed when the friction ,ensure that the body axis and never wear.
在閥體下軸的底部采用高硬度耐磨合金球面止推墊和高硬度平墊。蝶板在運動過程中，所有產生向下的重力和磨擦力均集中在此。由于兩推力墊硬度高，接觸面積小長期運動無磨損，保證閥門開啟關閉輕松，永無下沉。
Valve in the bottom of the shaft using high hardness wear-resistant alloys spherical thrust pad hardness and high-pad. Butterfly Plate in the campaign process, all have a downward force of gravity and friction are concentrated here. As the two thrust pad hardness, small contact area and wear a long-term campaign to ensure that the valve closed to open easily, never sink
金屬對金屬多層次復合型硬密封結構是將多層次復合型密封圈安裝在閥板上的一種結構形式。多層次復合型金屬圈由不銹鋼金屬板和柔性石墨片重復疊加壓制而成，具有很高的強度和剛性；柔性石墨在高溫、高壓下仍有良好的密封性能。這兩種材料的剛柔相濟的特性，使得閥門適用于絕大多數介質、使用范圍廣、使用壽命長。
Metal on metal hardware multi-level complex will be sealed structure is a multi-level complex of ring valve installed in a board structure. multi-level complex of metal ring from stainless steel plates and flexible graphite-repeat stack from repression, is of high strength and rigidity; flexible graphite in high-temperature, high pressure is still good sealing perfo-rmance. The balanced characteristics of flexibility and toughness of these two materials, makes the valve and the application of the overwhelming majority of media, the use of a wide range of long life.
