产品结构特点 Construction features

1、上装式结构，即阀门的主要部件——蝶板是经由阀体上部的矩形中法兰口装入体腔的，当阀门需要检修时，无须将其从管线上拆下，只要花极少时间打开上盖便能连阀杆带蝶板从体腔中一起取出进行维修作业。

2、本阀门在进行维修作业的同时可以酌情保留管道中的介质，这便免除了使用方许多前期辅助工作，使维修变得较为简捷。

3、在一些特定的场合，本阀门在进行抢修期间可以不影响管道系统的正常运行，只要在取出蝶板组合件后迅速封闭上口便可立即恢复管道的带压运行，使抢修阀门造成的效益损失降低到最小程度。

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.
