DEVICE FOR SEALING A COUPLING

摘要

The device makes it possible to connect tightly first and second parts having a flange and locking or tightening means for the said flanges. The tightening or locking force applied to the locking of tightening means is multiplied in order to increase the compression force applied to a gasket or joint. Each flange has a conical surface of axis D and angle lambda . The device has two clips, each of which has a conical surface of axis D and angle mu , as well as an intermediate member in the form of a ring constituted by several interconnected segments and having an inner surface and an outer surface. Each inner peripheral surface has a conical surface of axis D and angle lambda able to cooperate with the conical surface of axis D and angle lambda of the first and second parts. Each outer peripheral surface has a conical surface of axis D and angle mu able to cooperate with the conical surfaces of angle mu of the clips.
