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.

Drip-Free Disconnect Valve

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.

Therefore, when the valve is disconnected, no liquid will be released. The notch 5 at the face 3 and face 4 inter face eases alignment of the two valve halves. One unique feature of this valve is that it can be incorporated in the design of the fluid components.

For example, it may be used in a logic unit to allow water to pass near logic modules. By making the valve integral with the fluid components, space requirements are minimized. Another unique feature of the valve design is the slight offset of faces 3 and 4 from the surfaces of their retainers. This feature eliminates the possibility that valve face 3 would interfere with the retainer of face 4 when the val...
