CA 2618758
The invention relates to an emergency disconnection system, especially for a fluid loading arm, comprising two valves which are joined together by means of a collar with a controlled opening, an actuator (400) comprising a single rod (401), and monoaxial kinematics such that a displacement of the rod (401) over a first part of the course thereof closes the two valves, and the displacement of the rod over the remainder of the course thereof opens the collar. Said system is characterised in that the actuator comprises means for ensuring the displacement of the rod (401) over said two parts of the course, said means being independently controlled on each of the parts and acting coaxially or essentially coaxially.
L'invention concerne un système de déconnection d'urgence, notamment pour un bras de chargement de fluide, du genre ayant deux vannes accolées à l'aide d'un collier à ouverture commandée, un actionneur (400) muni d'une tige (401) unique, et une cinématique mono axe telle qu'un déplacement de la tige (401) sur une première portion de sa course ferme les deux vannes et sur le reste de sa course, ouvre le collier, caractérisé en ce que l'actionneur comporte des moyens propres à assurer le déplacement de la tige (401) sur ces deux portions de course et commandés indépendamment sur chacune desdites portions, lesdits moyens agissant coaxialement ou sensiblement coaxialement.
