EMERGENCY DISCONNECTION SYSTEM

摘要

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.
