Abstract

Cette vanne comprend des organes interne 20 et externe 21 montés télescopiquement et pouvant se déplacer entre une position d'extension et une position rétractée. Un obturateur principal 35 ferme le passage d'écoulement axial, ménagé dans lesdits organes, dans le sens d'un écoulement descendant, en réponse au déplacement des organes vers la position d'extension. Un manchon d'obturation 50 ouvre un passage de dérivation pour égaliser les pressions de part et d'autre de l'obturateur principal avant sa réouverture en réponse au déplacement des organes vers la position rétractée. Application aux opérations de reconditionnement dans les forages.
