Title (EN) PRESSURE CONTROL VALVE FOR DOWNHOLE TREATMENT OPERATIONS
(FR) SOUPAPE DE COMMANDE DE PRESSION POUR OPÉRATIONS DE TRAITEMENT DE FOND DE TROU
Abstract:
(EN) A pressure control valve for downhole treatment operations includes a valve body including an inlet, an outlet, and a valve seat. A valve assembly is arranged in the valve body. The valve assembly includes a valve member selectively positionable on the valve seat to control fluid flow through the valve body. A piston assembly including a piston and a control fluid inlet is arranged in the valve body. The piston is operatively connected to the valve assembly. The piston is operable to bias the valve member toward a closed configuration upon exposure to a control fluid.
(FR) Soupape de commande de pression pour des opérations de traitement de fond de trou comprenant un corps de soupape comprenant une entrée, une sortie et un siège de soupape. Un ensemble soupape est disposé dans le corps de soupape. L'ensemble soupape comprend un élément de soupape pouvant être positionné de manière sélective sur le siège de soupape pour commander l'écoulement de fluide dans le corps de soupape. Un ensemble piston comprenant un piston et une entrée de fluide de commande est disposé dans le corps de soupape. Le piston est relié de manière fonctionnelle à l'ensemble valve. Le piston sert à solliciter l'élément de soupape vers une configuration fermée lors de l'exposition à un fluide de commande.
