產品結構特點 Construction features

1、上裝式結構，即閥門的主要部件——蝶板是經由閥體上部的矩形中法蘭口裝入體腔的，當閥門需要檢修時，無須將其從管線上拆下，只要花極少時間打開上蓋便能連閥桿帶蝶板從體腔中一起取出進行維修作業。

2、本閥門在進行維修作業的同時可以酌情保留管道中的介質，這便免除了使用方許多前期輔助工作，使維修變得較為簡捷。

3、在一些特定的場合，本閥門在進行搶修期間可以不影響管道系統的正常運行，只要在取出蝶板組合件后迅速封閉上口便可立即恢復管道的帶壓運行，使搶修閥門造成的效益損失降低到最小程度。

1, the structure of the jacket type, i.e., a major part of the valve, butterfly plate is through the body in the upper part of the rectangular flange mouth into the coelomic cavity when the valve is in need of repair, need to be removed from the pipeline, as long as spend very little time to open the cover can be along the valve stem and disc from the body cavity for repair work.
 2. This valve can retain the medium in the pipe while maintaining the maintenance operation, which is exempted from many prophase auxiliary work of the user and makes the maintenance more concise.
 3, on certain occasions, during to repair the valve can not affect the normal operation of the pipeline system, as long as the closed flowing rapidly after take out the disc assembly can be an immediate restoration of pipeline operation under pressure to make benefit loss caused to repair the valve is reduced to a minimum.
