Abstract

Disconnect valves that allow for a quick break between fluid components release a finite amount of liquid when the two halves are separated. The drip-free disconnect valve described eliminates this release of liquid. The figure presents the drip-free disconnect valve in its open position. Before operating the valve, the two fluid components must be positively connected. Valve stem 1 can then be depressed to open the valve. Springs are placed in the two valve halves to ensure good sealing contact when the valve is closed (dotted representation in the drawing) and the fluid components are separated. 0-rings 2 provide a seal at metal-to-metal interfaces. The mating surfaces between face 3 and face 4 have been designed to be void of cavities that would allow for fluid entrapment.
