Title (EN) CONNECTOR WITH FLANGE FOR LIMITING BUCKLE PROPAGATION COMPRISING A DIFFERENTIAL PRESSURE VALVE FOR UNDERWATER FLUID-TRANSPORT PIPE
(FR) PIÈCE DE JONCTION À BRIDE DE LIMITATION DE PROPAGATION D'ÉCRASEMENT COMPRENANT UNE SOUPAPE DE PRESSION DIFFÉRENTIELLE POUR CONDUITE SOUS-MARINE DE TRANSPORT DE FLUIDES
Abstract:
(EN) The invention relates to a connector with a differential pressure valve (100) for an underwater fluid-transport pipe, comprising a valve body (102) inside which an inner chamber (106) is arranged, opening on one side towards the pipe and leading by the other side towards the outside, a piston (110) arranged so as to divide the inner chamber into an intake chamber (106a) and a discharge chamber (106b), the piston being movable between an open position in which the intake and discharge chambers communicate with one another and a closed position in which the intake and discharge chambers are sealed relative to one another, a loading screw (112) screwed into the valve body and comprising a bore (114) inside of which slides a rod (116) of the piston (110) and at least one tapping (118) leading into the discharge chamber and opening towards the outside, and a spring (120) loaded so as to hold the piston in closed position below a predetermined threshold pressure inside the intake chamber.
(FR) L'invention concerne une pièce de jonction à soupape de pression différentielle (100) pour conduite sous-marine de transport de fluides, comprenant un corps de soupape (102) à l'intérieur duquel est ménagée une chambre interne (106) s'ouvrant d'un côté vers la conduite et débouchant d'un autre côté vers l'extérieur, un piston (110) disposé de façon à départager la chambre interne en une chambre d'admission (106a) et une chambre de refoulement (106b), le piston étant mobile entre une position d'ouverture dans laquelle les chambres d'admission et de refoulement communiquent entre elles et une position de fermeture dans laquelle les chambres d'admission et de refoulement sont étanches l'une par rapport à l'autre, une vis de tarage (112) vissée dans le corps de soupape et comprenant un alésage (114) à l'intérieur duquel coulisse une tige (116) du piston (110) et au moins un perçage (118) débouchant dans la chambre de refoulement et s'ouvrant vers l'extérieur, et un ressort (120) taré de sorte à maintenir le piston en position de fermeture en- dessous d'une pression de seuil prédéterminée à l'intérieur de la chambre d'admission.
