Title
(EN) ADJUSTABLE TRUNNION VALVE AND RELATED METHODS
(FR) ROBINET À TOURILLON RÉGLABLE ET PROCÉDÉS ASSOCIÉS
Abstract
(EN) An adjustable trunnion valve includes an obturator, a valve stem, at least one valve seal, and a trunnion. The trunnion and obturator are configured to translate the obturator along a longitudinal axis extending through the trunnion and the obturator upon rotation of the valve stem beyond one or both of its open position and its closed position. A method of operating an adjustable trunnion valve having an obturator coupled to a trunnion and a valve stem includes passing a fluid through the adjustable trunnion valve and rotating the valve stem to rotate the obturator about an axis of rotation and to simultaneously translate the obturator in a direction along the axis of rotation while the obturator is supported by the trunnion and while the fluid flows through the adjustable trunnion valve.
(FR) L'invention concerne un robinet à tourillon réglable qui comprend un obturateur, une tige de robinet, au moins un joint d'étanchéité de robinet et un tourillon. Le tourillon et l'obturateur sont configurés de façon à faire effectuer une translation à l'obturateur le long d'un axe longitudinal s'étendant à travers le tourillon et l'obturateur lors de la rotation de la tige de robinet au-delà de l'une ou des deux de sa position ouverte et de sa position fermée. L'invention concerne également un procédé de fonctionnement d'un robinet à tourillon réglable, ayant un obturateur couplé à un tourillon et une tige de robinet, qui comprend le passage d'un fluide à travers le robinet à tourillon réglable et la rotation de la tige de robinet de façon à faire tourner l'obturateur autour d'un axe de rotation et à faire effectuer une translation simultanée à l'obturateur dans le sens de l'axe de rotation pendant que l'obturateur est porté par le tourillon et que le fluide s'écoule à travers le robinet à tourillon réglable.
