一种管道用整体回形卡瓦
摘要：
本发明公开了一种管道用整体回型卡瓦，属于连接装置技术领域。该卡瓦通过其内壁上设有的卡齿嵌入到管道外壁中，该卡齿与管道外壁嵌合后，卡齿与管道外壁之间能够产生制约其相对运动的作用力，从而阻止该卡瓦与管道外壁之间的相对运动；由于该瓦本体的外壁与密封机构的内壁连接后，本体与密封机构之间无相对滑动，因此，能够阻止该卡瓦与密封机构内壁之间的相对运动。当该卡瓦与管道外壁之间无相对运动，并且，该卡瓦与密封机构的内壁之间无相对运动时，该密封机构内壁与管道外壁之间也没有相对运动，因此，该卡瓦能够阻止外接的密封机构以管道轴线为旋转中心的旋转及左右平动。
摘要（英）：

The invention discloses an integral zigzag slip for a pipeline and belongs to the technical field of connecting devices. Clamping teeth embedded into the outer wall of the pipeline are arranged on the inner wall of the slip, and after the clamping teeth are embedded with the outer wall of the pipeline, acting force limiting relative motion of the clamping teeth and the outer wall of the pipeline can be produced between the clamping teeth and the outer wall of the pipeline, and accordingly relative motion between the slip and the outer wall of the pipeline is prevented. Due to the fact that after the outer wall of a slip body is connected with the inner wall of a sealing mechanism, relative sliding is not produced between the body and the sealing mechanism, and the relative motion between the slip and the inner wall of the pipeline can be prevented. When the relative motion is not produced between the slip and the outer wall of the pipeline and relative motion is not produced between the slip and the inner wall of the pipeline, no relative motion is produced between the inner wall of the sealing mechanism and the outer wall of the pipeline. Therefore, the slip can prevent rotation and horizontal translation of the external sealing mechanism with the pipeline axis as the rotation center.
