A subsurface safety valve has a closure sleeve (122) or rod (38) mounted below the closure mechanism. Control signal pushes the sleeve up (uphole) or down (downhole), whichever is applicable, which causes the closure element (10) to rotate (or slide, or otherwise translate) to its open position. A loss of control signal allows the closure spring (24) to push the sleeve or rod downhole (or uphole, whichever is appropriate). This movement causes the closure element to be driven to its closed position against the seat.
L'invention concerne une soupape de sécurité de subsurface comprenant un manchon de fermeture (22) ou une tige (38) monté au-dessous du mécanisme de fermeture. Un signal de commande pousse le manchon vers le haut (tête du puits) ou vers le bas (fond du puits), en fonction des besoins, entraînant la rotation de l'élément de fermeture (10) (ou le glissement ou une autre forme de translation) dans sa position ouverte. Une perte de signal de commande permet au ressort de fermeture (24) de pousser le manchon ou la tige dans le fond du puits (ou dans la tête du puits, en fonction des besoins). Ce déplacement entraîne l'élément de fermeture dans sa position fermée contre le siège.
