Title (EN) SEAL ASSEMBLIES FOR USE WITH FLUID VALVES
(FR) ENSEMBLES JOINTS À UTILISER AVEC DES SOUPAPES DE FLUIDE
Abstract:
(EN) Seal assemblies for use with fluid valves are described. An apparatus includes a cage (124), a plug (122) having a seal gland (148) and a seal assembly (300) to be at least partially positioned in the seal gland. The seal assembly includes a back-up ring (302) having a wedge-shaped protrusion (310) and a seal defining a wedge-shaped groove (312) to receive the protrusion. A pressure is to act on the back-up ring to urge the protrusion into the groove. An engagement between the protrusion and the groove is to urge the seal into sealing engagement with an inner surface (126) of the cage.
(FR) L'invention concerne des ensembles joints destinés à être utilisés avec des soupapes de fluide. Un appareil comprend une cage (124), un bouchon (122) possédant une presse-étoupe (148) et un ensemble joint (300) à positionner au moins partiellement dans la presse-étoupe. L'ensemble joint comprend une bague d'appui (302) possédant une saille en forme de coin (310) et un joint délimitant une rainure en forme de coin (312) pour recevoir la saillie. Une pression agit sur la bague d'appui pour pousser la saillie dans la rainure. Une mise en prise entre la saillie et la rainure consiste à pousser le joint en prise étanche avec une surface intérieure (126) de la cage.
