Waste pipe branching

Abstract

In waste transport piping of a waste collection sy stem that is sectioned and / or contains waste collection units communicating with the piping, branch pipes and / or waste collection units are connected to the piping through branching connections (10) and branching orifices in the waste transport pipe, for introducing waste into the transport pipe during an active phase of an associated branch pipe and / or waste collection unit. In such piping, substantially the full, uninterrupted circumferential surface of said transport pipe is completed in the area of the associated branch pipe or waste collection unit in an inactive phase of the latter. A branching connector (10) for performing such a completion of the transport pipe circumference has a connector valve (17) supported in the area of said orifice for movement between a transport position (TP) covering the orifice and a supply position (SP) exposing the orifice and at least partially blocking the cross section of the waste receiving transport pipe.

Description

Technical field [0001] The present invention relates to a vacuum-operated waste collection system, especially a pipeline used for waste transportation. The pipeline is divided into one or more branches for guiding the air and waste flow in the pipeline and / or guiding the air And waste material enters the pipeline. Background technique [0002] Regardless of whether it is a fixed or movable vacuum-operated waste collection system, its transportation pipeline contains multiple branches, connected to the main road of the transportation pipeline or branched from the main road. There are two functions of setting branches. One is to divide the piping system (pipeline) into several sections or branches, and the other is to connect a transportation pipeline to a waste collection warehouse and / or waste collection point through a waste discharge valve, such as An independent waste inlet or a waste tank is directly connected. This branching in the traditional waste pipeline system can pot...

AI Technical Summary

Problems solved by technology

As far as sectional branches of the piping system are concerned, this type of problem can be at least partly solved by using relatively expensive sectional valves, while as far as the connection of the waste collection storehouse and / or waste collection point is concerned, the waste discharge valve is conveniently located below the waste discharge valve. Need to reserve a lot of branch space, because most of the waste discharge valve is a baffle type design, which requires a lot of space for switching activities

[0003] Each branch of such a vacuum-operated waste collection system itself and / or the area below each section or waste discharge valve inevitably locally widens the cross-sectional area of ​​the piping, increasing the overall vacuum volume requirement, thereby Increased energy consumed by the system, especially at the junction of branches and / or waste collection devices, causing turbulence and pressure changes, resulting in a significant drop in pressure and reduced air velocity, affecting the amount of vacuum required by the system
