CRIMP-TYPE COUPLING, CRIMPING TOOL, AND METHOD OF CRIMPING |
摘要 |
A coupling installed by crimping has an angularly oriented conical surface at an open end surrounded by a ring which receives a pipe element. Dies move radially toward the coupling on jaws of a crimping tool and engage the conical surface along a single line of contact to effect a crimp which secures the coupling to the pipe. The radially applied force has radial and ax-ial components. The radial component effects the crimp, the axial component deforms a channel in the coupling in which a seal is located. The seal is deformed between the coupling and the pipe to effect a fluid tight joint. The coupling may have a circumferen-tial rib which projects radially outwardly. Registration dogs engage the coupling and provide a reaction surface against the axial force component.
