    • A ball valve having a main body portion with a throughbore and a rotatable ball valve closing off the throughbore. The ball is of resilient plastic and is comprised of a pair of interconnected sides defining a slot therethrough. The valve body portion has cams associated with the throughbore engageable with the ball side when the same is rotated. The sides, in a first position, close off the throughbore, the cams engage the flexible sides and camming the same into fully seated closure of the throughbore. When rotated away from engagement with the cams, the slot in the ball valve is aligned with the throughbore allowing fluid flow therethrough.
    • 一种球阀,其具有带有通孔的主体部分和从所述通孔闭合的可旋转球阀。 球是弹性塑料,并且由一对互连的侧面组成,这些侧面限定穿过其中的槽。 当其旋转时,阀体部分具有与通孔相关联的凸轮,其可与球侧接合。 这些侧面处于第一位置,关闭了通孔,凸轮与柔性侧面接合并将其相对于通孔的完全固定的封闭件。 当旋转离开与凸轮接合时,球阀中的槽与通孔对准,允许流体流过其中。
