Abstract

The pipework is for a floating-roof reservoir for liquid of different density from water, and is used to drain off rainwater. It has a flap-valve consisting of an elastic membrane (14) separating the liquid in the reservoir from water in the pipework. Displacement of the membrane occurs when the liquid has different density from water, uncovering apertures (12, 13, 17) in the pipe walls, allowing flow past a partition (9) across the pipe. The membrane sits snugly over the apertures, blocking the flow path, when the densities are equal. The flap-valve is at the same level as the bottom of the reservoir.
