valve gate

基本解释

The speed of the valve gate is open or closed to complete a move to indicate the time required.
启闭速度是用阀门完成一次开启或关闭动作所需的时间来表示。
Flat bottom direct design prevents sundries from accumulating, which guarantees valve gate sealing performance for long time use.
平底直通式设计，阀体避免杂物堆积，蝶阀保证长期使用不影响阀门密封性能。
The valve gate will cut off medium and be in the sealed state when the butterfly disc moves to the vertical place with pipe axis.
当蝶板运行到与管道轴线相垂直时，阀门即切断介质处于密封状态。
