    • A coupling for joining pipe elements in end to end relation is disclosed. The coupling includes interconnectable coupling segments having connection members at opposite ends. The connection members are tightenable for drawing the segments toward one another and into engagement with the pipe elements. Each segment has a concavity positioned between inwardly projecting arcuate surfaces that engage grooves in the pipe elements. The concavities house a sealing member that extends circumferentially around the pipe elements. Angularly oriented surfaces are positioned adjacent to the connection members. The surfaces on facing segments engage one another and cause the segments to rotate in opposite directions about an axis perpendicular to the pipe elements. The concavities are angularly oriented with respect to the axis so that when the segments rotate, the cavities receive the sealing member without distorting it. A method of joining pipe elements end to end is also disclosed.
    • 公开了一种用于以首尾相连的方式连接管件的联接器。 该联轴器包括在相对端具有连接构件的可互连的联轴节。 连接构件是可收紧的,用于将节段朝向彼此拉动并与管道元件接合。 每个节段具有位于向内突出的弧形表面之间的凹部,该弧形表面接合管元件中的凹槽。 凹部容纳围绕管元件周向延伸的密封构件。 角度定向的表面定位成与连接构件相邻。 面对部分上的表面彼此接合并且使得部分围绕垂直于管道元件的轴线在相反的方向上旋转。 凹部相对于轴线成角度地定向,使得当区段旋转时,空腔接收密封构件而不扭曲它。 还公开了一种首尾相接的管件连接方法。
