What is a Drainage device?

SCHEMATIC DIAGRAM OF AN AUTOMATIC DRAIN DEVICE

WHEREAS:

•It’s an automatic drain device which includes an

electrode sensor in a liquid collection cell. An

electronic control detects an electrical change in the

electrode sensor resulting from contact with liquid in

the liquid collection cell and energizes a drain valve

for a predetermined time effective to drain the liquid

collection cell.

•A cycle timer triggers the energization of the drain

valve when the electrode sensor fails to provide the

required electrical change for a predetermined cycle

time.

•Test inputs permit driving the electronic control to

simulate sensing of liquid, and also permit

Drain discharge device

A drain discharge device for

discharging effluent comprises a

valve with a single outlet and a

plurality of inlets that selectively

connects the single outlet to one

of inlets in turn. The inlets, each

of which corresponds to an outlet

of an effluent discharging

device, such as an air

deviceAn aircraft drain device for

interposition between a potable water

line (e.g., the drain line from an ice

drawer) and a gray water line leading

to a drain mast or other external drain.

The drain device includes a

housing, an inlet adapted for

connection to the potable water
