Definitions

  • the present invention relates to a branch line for downpipes according to the preamble of claim 1.
  • Geberit Sovent is a fitting which provides a cost-effective and sophisticated solution for the delivery of waste water to wastewater sewer lines in multi-storey buildings, such as high-rise buildings.
  • a negative pressure in the supply line during operation should be largely prevented.
  • the negative pressure is created by the effluent flowing in the downpipe and can be so large, especially at large fall heights, that wastewater is sucked out of the existing in the supply line siphons. Consequently, the siphon no longer fulfills the function as a closure element between downpipe and the corresponding waste water drains, such as toilet drain etc.
  • the formation of the negative pressure can be reduced, for example, in which braking elements or guide elements are arranged which brake or redirect the wastewater flowing in the direction of the fall in the region of the supply line.
  • this has a negative effect on the power or the volume flow of the branch line piece, which means that line branch pieces with larger pipe diameters must be used in order to achieve a comparable performance. This is again undesirable, since so greater installation space is required.
  • the invention has for its object to provide a line branch piece, which overcomes the disadvantages of the prior art.
  • a line branch piece is to be created whose power is increased while maintaining the same size and whose performance is kept constant at a reduced size.
  • the curved deflection surface preferably has the shape of a channel which extends along the flow curve or flow line.
  • the channel bundles the wastewater to the said beam and then leads this tangentially to the wall of the flow area.
  • the deflection surface or the channel is concave.
  • the flow curve or flow line can be formed in the region of the deflection surface as a straight axis or as a curved line.
  • a flow divider is arranged in the direction of fall before the deflection, wherein the flow divider, the waste water jacket can be torn off.
  • the flow divider preferably directs the waste water directly to the deflection section.
  • the deflection region is arranged in the direction of fall directly after the upper downcomer section, and / or the flow-through region is arranged immediately after the deflection region, and / or the lower downflow section is arranged immediately after the flow-through region.
  • the feed line section preferably has an opening region in which the feed line opens into the line branch piece via the feed line section, wherein the mouth region is separated from the flow region by a dividing wall, so that the entry of waste water from the flow region into the mouth region is prevented.
  • a bleed passage is arranged between the flow area and the feed line section, via which pressure differences between the flow area and the mouth area can be compensated.
  • FIGS. 1 and 2 show a line branch piece 1 for use in wastewater sewer pipes in multi-storey buildings.
  • the line branch piece 1 is used for the connection of a waste water supply line from a floor in the downpipe, which extends from floor to floor, usually over the entire building height.
  • the supply line is therefore connected via the branch line piece 1 with the down pipe.
  • the line branch piece 1 comprises an upper downcomer section 2 with an inlet opening 3, a deflecting section 4 adjoining the upper downcomer section 2 and a lower downpipe section 5 adjoining the deflecting section 4 with an outlet opening 6, and at least one inlet section 7 via which additional wastewater is introduced into the downpipe becomes.
  • the upper downcomer section 2, the deflecting section 4 and the lower downcomer section 5 are surrounded by a wall 11, 20.
  • the upper downcomer portion 2 of the line branch piece 1 is connected to an upper downpipe, not shown here, and the lower downcomer portion 5 is connected to a lower downpipe, also not shown here.
  • the supply line section 7 communicates with the drains of, for example, a dwelling in a multi-storey building in connection and is sealed there via a siphon to the line system out, as explained above.
  • the connection between the pipe section 1 and the downpipe or the supply line is preferably via a material connection, such as a welded connection.
  • FIG. 3 a schematic representation of the wastewater is shown.
  • the drop lines are arranged so that their central axis lies in the vertical V. Consequently, the waste water flows in the vertical V along a fall direction F and forms on the wall 20 of the downpipe and partly also in the downcomer sections 2, 3 a circulating cylindrical wastewater film or wastewater jacket W.
  • wastewater which is in the Essentials Water and solids composed, with respect to flow effects is not significantly different from water.
  • the diameter of the down pipe is to be dimensioned so that at the maximum volume flow, the wastewater as waste water jacket W flows away, whereby the air column L is present.
  • the wastewater is introduced from the upper downcomer via the inlet opening 3 into the branch pipe 1 along the fall direction F, which corresponds essentially to the vertical V,.
  • the wastewater passes through the upper downcomer section 2 and is deflected by the deflecting section 4 according to the description below.
  • additional wastewater is introduced into the downpipe via the supply line section 7.
  • the deflected wastewater mixes with the additional wastewater and leaves the line branch piece 1 via the lower downflow section 5 or the outlet opening 6 to the lower downflow line. Due to the flow characteristics, a waste water jacket W and an air column L are then created in the lower downpipe as soon as the wastewater has traveled a certain distance.
  • the deflection section 4 here comprises a deflection region 8 which deflects the wastewater W from the fall direction F, and a flow region 12 arranged downstream of the deflection region 8 in the direction of fall F.
  • the flow region 12 is preferably immediately after the deflection region 8, ie directly to the deflection region 8 Subsequently, arranged, while the deflection region 8 directly or directly adjoins the upper downcomer section 2.
  • the flow area 12 then opens directly into the lower downflow section 5, thus the lower downcomer section 12 arranged immediately after the flow area 12.
  • the deflection region 8 comprises a deflection surface 10 running along a flow curve or flow line M and curved around the flow curve or flow line M for bundling the wastewater as a jet S.
  • the curvature of the deflection surface 10 is selected such that the waste water jacket W passes through the deflection surface 10 is essentially bundled as a beam S and leaves as the beam S, the deflection surface 10 again.
  • the flow curve or the flow line M can also be referred to as the center axis of the curvature of the deflection surface 10.
  • the deflection surface 10 seen to the fall direction F with respect to the fall direction F is at a first angle ⁇ . It can also be said that the deflection surface 10 is in a plane E, which extends through the falling direction F, with the angle ⁇ to the direction of fall F.
  • the level E is in the FIG. 4 parallel to the drawing sheet surface.
  • the plane E extends substantially through the center axis of the upper downcomer section 2 and the lower downcomer section 5. With respect to the plane E, the deflection surface 10 extends in the direction of the fall direction F at a second angle ⁇ . This can be done in the FIG. 6 be recognized.
  • the first angle ⁇ is preferably selected in the range of 90 ° to 175 °, in particular in the range of 125 ° to 155 °, particularly preferably 140 °.
  • the second angle ⁇ is preferably selected in the range of 0 ° to 45 °, in particular in the range of 10 ° to 30 °, particularly preferably 19 °.
  • the curved deflection surface 10 is thus directed with its central axis M substantially tangentially to the wall 11 of the flow area 12.
  • the sewage steel S impinges substantially tangentially on the wall 11 of the flow area 12. Due to the tangential impingement of the sewage jet S is guided along a flow curve through the flow area 12 and rotated about a relative to the wall 11 centrally through the flow area 12 extending curve 23 in rotation.
  • the waste water jet S flows along the wall 11 through the flow area 12.
  • the waste water flows along the Wall 11 helically in the direction of F flows.

  • the flow direction of the waste water is deflected by the deflection surface 8 laterally to the plane E and the curve 23, so that the wastewater is passed tangentially to the wall 11 and thus the rotation about the curve 23 can be achieved.
  • This deflection 19 is in the FIG. 5 shown. Consequently, the waste water rotates after the deflection about the curve 23.
  • the maximum deflection 19 is preferably in the region of the end 21 of the deflection region eighth
  • the flow line or the flow curve is preferably a curve that is continuous in the mathematical sense, so that the wastewater undergoes, as far as possible, a turbulence-free deflection.
  • the deflection region 8 is designed so that the wastewater is deflectable with respect to the fall direction F.
  • the deflection is such that the wastewater as a sewage jet tangentially to the wall 11 of the flow area 12 occurs. Due to the tangential impingement, the waste water jet is set in rotation about the line 23 extending centrally through the flow area 12, and can be guided as a rotating flow along the wall 11 through the flow area 12.
  • the described rotation of the wastewater has the advantage that a large deceleration of the wastewater and thus a reduction in performance can be avoided.
  • the rotation of the waste water along the wall 11 thus has the advantage that with a constant diameter of the down pipe, a larger volume flow can be achieved or the diameter can be reduced at a constant volume flow.
  • the rotation also makes it possible for an air column L to extend from the upper downcomer section 2 as far as the lower downcomer section 5. Thus, there is no interruption of the air column by wastewater and performance is not negatively affected. Due to the continuous air column there is no negative pressure in the system and thus it can not lead to an emptying of the siphons in the supply lines. In addition, no congestion zones with other negative effects, such as the pulsation of the air column, arise.

  • FIG. 4 can be well recognized that the wastewater is guided after deflection by the deflection region 8 on the wall 11 opposite the feed line section 7 in the fall direction F.
  • the same is true in the FIG. 6 shown.
  • the guidance of the wastewater with respect to the supply line section 7 has the advantage that the wastewater can be continuously stirred on a wall, which does not cause the rotation to break off.
  • FIG. 7 is a sectional view taken along the section line VII-VII in the FIG. 1 shown. Consequently, it is directed to the lower portion of the deflection section 4 to the lower downcomer section 5 out.
  • the transition between the flow area 12 and the lower downcomer section 5 is designed so that the wastewater flows tangentially into the lower downcomer section 5. Consequently, the lower portion 15 is immediately prior to the mouth in the lower downcomer section 5 tangential to the wall 20 of the lower downcomer section.
  • Die tangential flow of the lower downcomer section has the advantage that no storage zone for the wastewater in the lower downcomer section can arise.
  • the curved deflection surface 10 has the shape of a channel 24, wherein the channel extends substantially along the central axis M.
  • the deflection region 8 has, in particular, the shape of a pipe bend 9, wherein the channel 24 or the deflection surface 10 is then provided by the pipe bend 9.

  • the flow divider 18 is preferably arranged such that the total amount of waste water is diverted to the deflection region 8.
  • the flow divider 18 also has the advantage that the disruption of the film flow, the pulsation of the air column L and thus the resulting pressure differences in the branch line piece can be reduced
  • the flow area 12 is, as already mentioned above, directly in connection with lower downcomer section 5, in which then the wastewater flows from the flow area.
  • the flow area 12 with a portion 25 of the wall 11 at an angle ⁇ is angled or inclined to the direction of fall F and the vertical V. This is in the FIG. 4 shown.
