Pivoting Pipe Coupling Having a Movable Gripping Body

Номер: US20120256415A1
Автор: Douglas R. Dole
Принадлежит: Victaulic Co

A coupling for securing pipe elements together in end-to-end relation has segments joined at one end by a pivot attachment and at an opposite end by an adjustable connection member. The segments surround a central space which receives the pipe elements. A gripping body is captured between the segments. The segments have angularly oriented reaction surfaces. The gripping body has angularly oriented contact surfaces which interface with the reaction surfaces. When the segments are drawn toward each other by the connection members, interaction between the reaction surfaces and the contact surfaces forces the gripping body radially inwardly. Inwardly facing arcuate surfaces on the segments and the gripping body engage and retain the pipe elements. A method of inserting pipe elements into the coupling while the segments and the gripping body are supported on a seal is also disclosed.
