Compact aircraft galley plumbing system
View Patent ↗An aircraft galley plumbing is disclosed comprising water distribution components and assemblies to allow installation in a wet/refrigerated reduced foot print galley. The system includes a single potable water distribution manifold with quick disconnect couplings for the GAINS and built in air bleed devices facilitate rapid drainage and easy installation. The system also includes a compact pressure check valve to control filling operation and drain down of the potable water system. The use of a compact air stop valve and integrated master distribution block (manifold) and water filter system further enhance the system.
1. A plumbing system for an aircraft galley, comprising:
a potable water distribution manifold having quick disconnect couplings for associated GAINS, the potable water distribution manifold further comprising air bleed devices for facilitating rapid drainage;
a compact pressure check valve to control a filling operation and a drain down of circulating potable water;
a compact air stop valve for controlling flow through the plumbing system;
an integrated master distribution manifold coupled to a water filter system; and
a supply conduit system and a drainage conduit system for supplying and draining water, respectively.
2. The plumbing system of claim 1 , wherein potable water is supplied to the plumbing system from above.
3. The plumbing system of claim 1 , wherein potable water is supplied to the plumbing system from below.
4. The plumbing system of claim 1 , further comprising a surface mounted sink and sink drainage line.
5. The plumbing system of claim 1 , further comprising an air stop valve manual override mechanism.
6. The plumbing system of claim 1 , further comprising a pair of filtration units.
7. The plumbing system of claim 6 , wherein venting partially occurs when air is forced through the filtration units.
8. The plumbing system of claim 6 , wherein one line from the filtration units feeds the potable water distribution manifold and a second line supplies water to a potable water faucet.
9. The plumbing system of claim 1 , further comprising a remote emergency potable water shut off valve.
10. The plumbing system of claim 1 , further comprising a backflow prevention valve manual override controlled by a cable.
