Title (EN) SELF-CENTERING METAL-TO-METAL SEALS FOR USE WITH VALVES
(FR) JOINTS D'ÉTANCHÉITÉ MÉTAL-MÉTAL À AUTO-CENTRAGE POUR UNE UTILISATION AVEC DES VANNES
Abstract:
(EN) Self-centering metal-to-metal seals for use with valves are described herein. An example apparatus includes a disc-shaped valve plug having a first metallic sealing surface extending circumferentially about a peripheral edge of the valve plug. The first metallic sealing surface has a first curved profile. The example apparatus further includes a valve seat defining an orifice and having a second metallic sealing surface having a second curved profile that is complimentary to the first curved profile so that the first and second metallic sealing surfaces form a metal-to-metal seal when the first and second metallic sealing surfaces are in contact.
(FR) L'invention concerne des joints d'étanchéité métal-métal à auto-centrage pour une utilisation avec des vannes. Un exemple d'appareil comprend un clapet de vanne en forme de disque ayant une première surface d'étanchéité métallique s'étendant de manière périphérique autour d'un bord périphérique du clapet de vanne. La première surface d'étanchéité métallique a un premier profil incurvé. L'exemple d'appareil comprend en outre un siège de vanne définissant un orifice et ayant une seconde surface d'étanchéité métallique ayant un second profil incurvé qui est complémentaire du premier profil incurvé de telle sorte que les première et seconde surfaces d'étanchéité métalliques forment un joint d'étanchéité métal-métal quand les première et seconde surfaces d'étanchéité métalliques sont en contact.
