Title (EN) GRIPPER RING FOR A TUBE COUPLING
(FR) BAGUE FORMANT GRIFFE POUR ACCOUPLEMENT DE TUBES
Abstract: front page image
(EN)A gripper ring for a tube coupling, said coupling comprising a one piece or divisible nipple (1) and a sealing ring (2), said gripper ring (3) being adapted to be situated axially outside of the sealing ring (2) and having an external conical surface adapted to cooperate with a complementary conical surface inside the nipple (1) or inside an attached element (4) of the nipple (1), in order to cause compression of the gripper ring (3). The gripper ring relates to the problem of mounting a tube (5) in the coupling when the coupling is in its use condition, namely the problem to force the tube (5) through the gripper ring and the sealing ring without meeting a large resistance. This is achieved by the features that the inner surface of the gripper ring (3) is conical substantially in its entire length, and that the axially innermost end of the gripper ring (3) is tapered in such a manner that the sealing ring (2) is caused to expand when the gripper ring (3) is pressed axially against the sealing ring (2).
(FR)Une bague formant griffe pour un accouplement de tubes, cet accouplement comprenant un raccord en une piece ou divisible (1) et une bague d"etancheite (2), la bague (3) etant concue pour etre positionnee axialement a l"exterieur de la bague d"etancheite (2) et ayant une surface conique externe concue pour cooperer avec une surface conique complementaire a l"interieur du raccord (1) ou a l"interieur d"un element attache (4) du raccord (1), de maniere a comprimer la bague (3). La bague est destinee au montage d"un tube (5) dans l"accouplement lorsque celui-ci est en condition d"utilisation, pour forcer le tube (5) au travers de la bague et de la bague d"etancheite sans rencontrer une forte resistance. Ce resultat est obtenu en donnant a la surface interne de la bague (3) une forme sensiblement conique sur toute sa longueur, et par le fait que l"extremite axialement la plus a l"interieur de la bague (3) est conique de telle maniere que la bague d"etancheite (2) est forcee de se dilater lorsque la bague (3) est comprimee axialement contre la bague d"etancheite (2).
