<p>The device consists of a collection well or basin for liquid. A riser emerges from the bottom of the basin at a certain inclination to the horizontal plane. This riser runs through a bend and, in some cases, a reducer into a vertical pipe, which connects to an essentially U-shaped piece of pipe with a horizontal outlet. When the basin is filled with liquid, and additional liquid is supplied in a flow that exceeds the minimum flow that can run continuously through the device, a liquid seal is formed in the piece of pipe. Since liquid emerges from this piece of pipe into the outlet, a vacuum is created in the vertical pipe which sucks the liquid out of the basin, in the manner of a siphon. The liquid emerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in drainage systems without the required self-cleansing effect being lost, even if water-conserving flush toilets are connected to the system. Other areas of application are irrigation and the metering of liquids in batches.</p> |
