Liquid-plug-creating device |
摘要 |
A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content. The device permits the use of small-diameter pipes in house drainage systems while assuring the required self-cleansing effect, even if water-conserving flush toilets are connected to the device. Other fields of application of the device are irrigation and the metering of liquids in batches.
