Definitions
- the present invention relates to a deflection bend for a downpipe according to the preamble of claim 1.
- Downpipes are used to carry away wastewater and are usually arranged vertically in buildings. In many downpipes there are also sections that run horizontally or slightly inclined to the horizontal, for example at an angle of a few degrees. The vertically extending section is connected to the horizontally extending section via a deflection bend for the deflection from the vertical to the horizontal.
- Such a deflection bend is known, for example, from EP 1 882 786.
- the transition between a vertically extending section and a horizontally extending section is preferably designed in such a way that the wastewater is diverted with as little loss as possible. As a result, the wastewater still reaches the horizontally extending section with great energy, so that the wastewater can flow through the horizontally extending section over a large distance if possible.
- people have started to provide two 45° bends, which are connected to one another via a straight piece of pipe. The hydraulic losses could be reduced.
- this solution has the disadvantage that a lot of installation space is required.
- this solution has the disadvantage that a bypass line must be provided for pressure equalization in the case of large head heights.
- the deflection bend disclosed in EP 2 952 752 offers a remedy here to a certain extent.
- the deflection bend has a guide element in the area of the curve section which prevents the flow medium from sloshing across the direction of flow. This has the advantage that the above-mentioned workaround solution can be dispensed with.
- the invention is based on the object of providing a deflection bend which keeps the flow loss as small as possible and creates more flexible installation options.
- a deflection bend for a downpipe for discharging a multi-phase flow medium in particular consisting of water, solids and air, comprises,
- a guide structure arranged on the inside in the curve section or in the deflection bend on the outside of the curve for guiding the flow medium in the curve section.
- the guide structure has a channel-shaped guide section and at least two guide steps with step surfaces on each side of the channel-shaped guide section.
- the guide surfaces of the flow divider and the step surfaces are arranged relative to one another in such a way that a partial volume of an annular flow opened up by the flow divider is directed to the step surfaces.
- the advantage is that the entire water volume of the ring flow is divided between the channel-shaped guide section and the guide steps. This allows a directed flow to be achieved without lateral waves.
- the confluence of the flow medium is distributed over a greater length in the curve section, whereby the flow is calmed overall and experiences less loss.
- the flow divider is arranged comparatively close to the guide structure, that is to say no further than a dimension which corresponds at most to the pipe diameter of the first pipe section.
- the guide stages ensure controlled flow deflection, which means that the flushing performance is not impaired with compact deflection bends. Consequently, the deflection bend can also solve a preferred task that the deflection bend should be designed to be more compact.
- branches such as angle branches or bottom branches, or turning elements to be connected to the top of the deflection bend.
- Such branches or turning elements are located, for example, at a short distance from the top of a building floor, through which the first pipe section extends.
- a horizontal drain pipe connected to the second pipe section can be designed for a longer period of time with a minimal gradient.
- the cross-sectional shape of the curve section is designed by the arrangement of the guide structure in such a way that movement of the flow medium, in particular the water and the solids, transversely to the flow direction is suppressed or prevented.
- the guide steps and the wall surfaces preferably run in the flow direction of the flow medium.
- a reference level is used to define relative positions between individual features.
- the reference plane runs through the first central axis.
- the reference plane continues to run at right angles to the second central axis. In other words, the reference plane runs at right angles to the plane of symmetry of the pipe bend and through the first central axis.
- the guide structure is arranged such that the partial volume of the annular flow hits the guide structure directly from the side of the reference plane that is opposite the flow divider.
- the ring flow of this partial volume is introduced directly into the guide structure.
- the guide structure extends maximally to the reference plane in a projection plane that extends at right angles through the first central axis and is at the level of the entry into the curve section.
- the guide surfaces of the flow divider extend to the reference plane.
- the guide surfaces of the flow divider do not extend to the reference plane, with the partial volume of the torn ring flow leaving the guide surfaces on both sides as a jet that flows on the inner surface of the first pipe section, and the ring flow, which flows downwards outside the guide surfaces of the flow divider flows, entrained in the direction of the jet to the guide walls.
- the step surfaces are curved surfaces which extend curved around the curve axis.
- the step surfaces are preferably connected to one another via wall surfaces, the wall surfaces being at least partially at an angle of -10° to +10°, in particular essentially parallel, to a plane passing through the first central axis and the second The central axis is spanned.
- Essentially parallel is to be understood as meaning that the wall surfaces are parallel or at a small angle to the plane in question.
- the wall surfaces and the step surfaces preferably run in the flow direction of the flow medium.
- the wall surfaces prevent the flow medium from sloshing along the pipe wall transversely to the flow direction, which means that the performance of the deflection bend and thus also the flushing performance can be improved.

- the guide surfaces extend, viewed in a projection plane running at right angles to the first central axis, over a circular arc on the inside of the first pipe section around the first central axis.
