Title (EN) DEEP SET SAFETY VALVE
(FR) SOUPAPE DE SÉCURITÉ À RÉGLAGE PROFOND
Abstract:
(EN) An actuator sub for generating hydraulic pressure having a sub housing which includes (i) an outer surface, (ii) a main flow passage extending though the sub housing, and (iii) a wall space formed between the main flow passage and the housing outer surface. At least a first hydraulic tube is position in the wall space and an equalization port is configured to transmit pressure in the main flow passage to the first hydraulic tube. A drive motor driving an bi-directional hydraulic motor, are positioned in the first hydraulic tube, with the hydraulic motor being configured to output fluid to a fluid outlet of the first hydraulic tube, and the hydraulic motor, when not under power, allowing the reverse flow of fluid through the hydraulic motor. The actuator sub includes the absence of a check valve along a path carrying fluid between the hydraulic motor and the outlet of the second hydraulic tube.
(FR) La présente invention concerne un raccord d'actionneur pour générer une pression hydraulique ayant un boîtier de raccord qui comprend (i) une surface externe, (ii) un passage d'écoulement principal s'étendant à travers le boîtier de raccord, et (iii) un espace de paroi formé entre le passage d'écoulement principal et la surface externe de boîtier. Au moins un premier tube hydraulique est positionné dans l'espace de paroi et un orifice d'égalisation est conçu pour transmettre une pression dans le passage d'écoulement principal au premier tube hydraulique. Un moteur d'entraînement, entraînant un moteur hydraulique bidirectionnel, est positionné dans le premier tube hydraulique, le moteur hydraulique étant conçu pour délivrer un fluide à une sortie de fluide du premier tube hydraulique, et le moteur hydraulique, lorsqu'il n'est pas sous tension, permettant l'écoulement inverse de fluide à travers le moteur hydraulique. Le raccord d'actionneur est caractérisé par l'absence d'un clapet anti-retour le long d'un trajet transportant un fluide entre le moteur hydraulique et la sortie du second tube hydraulique.
