Title
(EN) A SEALING RING
(FR) BAGUE D"ETANCHEITE
Abstract
(EN)
A sealing ring of an elastic material is adapted to be applied to the spigot end of a pipe under expansion of the diameter of the ring. To obtain a particularly effective seal without any risk of overloading of the elastic material, neither during insertion into a pipe socket, assembling of the pipes nor later on as a consequence of oblique loads on the pipes, the sealing ring has a sealing member which consists of a hose (1) with a solid compression member (2) which is disposed inside the hose and is connected to the hose (1) through a flap (3). The flap has moreover an elongation (4) which can serve as a finger grip for the application of the sealing ring to the spigot end and counteract twisting of the sealing ring when the pipes are assembled.
(FR)
Une bague d"etancheite en materiau elastique est adaptee pour etre appliquee sur l"extremite male d"un tube par expansion du diametre de la bague. Pour obtenir un joint particulierement efficace sans aucun risque de surcharge du materiau elastique, ni pendant l"introduction dans un manchon de tuyau, pendant l"assemblage des tuyaux, ni apres comme consequence des charges obliques s"exercant sur les tubes, la bague d"etancheite possede un organe d"etancheite qui consiste en un tuyau (1) avec un organe de compression solide (2) qui est dispose a l"interieur du tuyau et est connecte au tuyau (1) par l"intermediaire d"une patte (3). La patte possede une elongation (4) qui peut servir de prise pour l"application de la bague d"etancheite sur l"extremite male et contrecarrer la torsion de la bague d"etancheite lorsque les tubes sont assembles.
