閥門再啟閉過程中旋塞與閥座相脫離,故閥門的啟閉非常輕松,而且密封面在開啟或關(guān)閉過程中不易擦傷,閥門使用壽命長。但采用手柄驅(qū)動力矩小,因此使用閥門的公稱尺寸通常不大。手輪手柄提升式旋塞閥結(jié)構(gòu)緊湊,體積小,流體阻力小。
機(jī)械十字架傳動提升式旋塞閥,工作原理為:開啟閥門時傳動裝置轉(zhuǎn)動閥桿的螺紋使旋塞體上升。旋塞和閥體密封面脫離后再驅(qū)動旋塞轉(zhuǎn)動90度到閥門全打開。關(guān)閉時傳動裝置使旋塞先轉(zhuǎn)動90度至關(guān)閉位置后,旋塞不再轉(zhuǎn)動,驅(qū)動力轉(zhuǎn)動螺紋后使旋塞下降,與閥
