Title
(EN) ANNULUS SAFETY VALVE SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE SOUPAPE DE SÛRETÉ ANNULAIRE
Abstract
(EN)
An apparatus includes a valve having a hollow body and an inner sealing assembly positioned in the hollow body. The inner sealing assembly includes a piston and can be moved between an open position and a closed position to selectively control flow along a flow path through the valve. The flow path includes a bore of the piston that allows flow through the piston, and pressure within the valve from a fluid in the flow path within the valve biases the inner sealing assembly toward the closed position to stop flow through the valve. Additional systems, devices, and methods are also disclosed.

Un appareil comprend une soupape ayant un corps creux et un ensemble d'étanchéité interne positionné dans le corps creux. L'ensemble d'étanchéité interne comprend un piston et peut être déplacé entre une position ouverte et une position fermée pour commander sélectivement l'écoulement le long d'un trajet d'écoulement à travers la soupape. Le trajet d'écoulement comprend un alésage du piston qui permet l'écoulement à travers le piston, et la pression à l'intérieur de la soupape à partir d'un fluide dans le trajet d'écoulement à l'intérieur de la soupape sollicite l'ensemble d'étanchéité interne vers la position fermée pour arrêter l'écoulement à travers la soupape. La présente invention concerne également des systèmes, des dispositifs et des procédés supplémentaires.
