ABSTRACT:
A disconnect composed basically of two halves each consisting of a poppet valve operable to isolate fluid with essentially zero fluid loss. The two halves are coupled together by a quickly releasable coupling which may be either a coupling ring tightened or loosened by a twisting motion, or a clamp operated by a pivoted handle. In either case an interlock device is provided to prevent disconnecting the two halves until both valves are in closed condition.
The "positive" feature of the device is one requiring a valve closing step before a disconnect step, and takes structural form in an eccentric lobe mounted on the valve operating stem. If some obstruction prevents the poppet from moving to its seat, the eccentric lobe cannot be rotated to the closed position, and the interlock prevents a disconnect.
