MAGNETIC COUPLING BOTTOM SAFETY VALVE

Abstract

The invention relates to a recoverable safety valve insert. In one aspect, the recoverable safety valve insert comprises an external housing having a central bore, and a valve closing mechanism coupled to the external housing near one end of the hole bottom of the central bore. According to this aspect, the recoverable safety valve insert further comprises a bore flow management actuator disposed in the central bore, the bore flow management actuator being configured to slide in order to move the valve closing mechanism between a closed state and an open state, and one or more safety valve insert magnets coupled to the bore flow management actuator, the one or more safety valve insert magnets being configured to magnetically couple with one or more inside-reach fitting magnets of a safety valve inside-reach fitting to slide the bore flow management actuator and move the valve closing mechanism between the closed state and the open state.
