它的工作原理如下: 一、开启过程 1在关闭位置,球体受阀杆的[wiki]机械[/wiki]施压作用,紧压在阀座上。
2当逆时针转动手轮时,阀杆则反向运动,其底部角形平面使球体脱开阀座。
3阀杆继续提升,并与阀杆螺旋槽内的导销相互作用,使球体开始无摩擦地旋转。 4直至到全开位置,阀杆提升到极限位置,球体旋转到全开位置。
二、关闭过程 1关闭时,顺时针旋转手轮,阀杆开始下降并使球体离开阀座开始旋转。
2继续旋转手轮,阀杆受到嵌于其上螺旋槽内的导销的作用,使阀杆和球体同时旋转90°。 3
快要关闭时,球体已在与阀座无接触的情况下旋转了90°。
4手轮转动的{zh1}几圈,阀杆底部的角形平面机械地楔向压迫球体,使其紧密地压在阀座上,达到xx密封。

It works as follows: 1, open process 1 in the closed position, the
sphere by the stem of the [wiki] machinery [/ wiki] pressure role,
pressed on the seat. 2 When the handwheel counterclockwise, the stem is the
reverse movement, which undocked from the bottom of the angular
plane to the sphere valve seat. 3 Stem continue to upgrade and with
the stem of the guide pin screw slot interaction, so that ball
began to spin without friction. Up to four fully open position,
valve stem to upgrade to the limit position, the sphere rotated
to the fully open position. 2, close the process of
A closed, clockwise rotation of hand wheel, valve stem began to
decline and to leave the seat begins to rotate the sphere. 2
continues to rotate hand wheel, spiral stem were embedded in its
slot on the role of guide pins, so that stem and the ball while
rotating 90 °. 3 is about to shut down when the ball has been no contact with
the valve seat under rotated 90 °. 4 hand-rotation of the final
laps, the bottom of the stem wedge angular plane mechanical ball to
the oppression so tightly pressed on the seat to achieve complete
sealing.
