Definitions

  • the invention relates to a vortex throttle device according to the preamble of claim 1.
  • One of the main tasks of rainwater management systems is to only gradually release the water that occurs during rainfalls into the sewer system or the surrounding waters. This is mainly used to protect against overload. In the case of bodies of water, it is used in particular for flood protection and water ecology. The discharge throttle is therefore an important component of rainwater management systems.
  • a vortex throttle device which has a vortex chamber and a stilling chamber, the vortex chamber and the stilling chamber being divided by a partition wall having a diaphragm opening.
  • the liquid inflow does not necessarily have to take place exactly tangentially in order to stimulate the formation of a vortex flow in the vortex chamber. Rather, it is sufficient that the liquid inlet is oriented in such a way that the liquid flowing into the vortex chamber has a tangential velocity component, its tangential velocity component preferably being greater than its radial velocity component. Nevertheless, the formation of a vortex flow is most strongly stimulated when the liquid inlet flows essentially tangentially into the vortex chamber.
  • the water leaves the vortex chamber through the aperture as a hollow jet, ie in the In the center of the beam, the air-filled vortex core extends through the aperture.
  • the cross-sectional area of the diaphragm opening used for the passage of water is restricted and the throttling effect of the diaphragm opening is increased.
  • the formation of the eddy flow can be promoted by the fact that the eddy chamber has an essentially axially symmetrical basic shape, the axis of rotation advantageously running parallel to the direction of the gravitational force in the operational orientation of the eddy throttle device.
  • the word component “basic” in the word “basic shape” is intended to indicate that the vortex chamber cannot be designed to be perfectly axially symmetrical, for example because of the confluence of the liquid inlet.
  • a vortex chamber that is not axially rotationally symmetrical can also be used, for example with an essentially square basic shape.
  • the liquid drain can lead out of the stilling chamber in any direction. So it can also lead out of the bottom of the stilling chamber. However, in the operational orientation of the vortex throttle device, it preferably leads out of the stilling chamber essentially horizontally, although it does not matter whether it leads out of the stilling chamber tangentially or not.
  • the partition wall having the aperture opening is detachably connected to the housing.
  • the eddy throttle device can be equipped with a suitable orifice opening to achieve a discharge characteristic desired for the respective application, ie discharge amount per unit of time depending on the inflow level.
  • the partition wall present in the vortex throttle device can be removed from the vortex throttle device and replaced by a partition with a smaller aperture.
  • the detachable connection of the partition to the housing can be realized, for example, in that the housing is permanently connected to a support ring protruding from the inner surface of the housing wall, which in turn is detachably connected to the partition.
  • the support ring can, for example, be welded or glued to the housing or be held by the latter in a form-fitting manner.
  • the support ring can be shrunk into the still "hot" plastic material immediately after production to achieve the positive hold.
  • a tapering and / or a circumferential bead can be provided on the housing in the operational orientation above the support ring and / or under the support ring.
  • the detachable connection of the partition wall and the support ring can be implemented, for example, by a type of bayonet lock between the partition wall and the support ring.
  • one part, support ring or partition, or at least a section of this part or one on it Part of the held element can be made of a ferromagnetic material, while the other part, partition or support ring, is provided with at least one holding magnet.
  • connection between the partition and the support ring does not necessarily have to be fluid-tight. It is sufficient if it is ensured that the leakage between the vortex chamber and stilling chamber does not impair the formation of the vortex flow in the vortex chamber and the throttling effect through the aperture.
  • the support ring can have an alignment surface
  • the partition wall can have a counter-alignment surface, the alignment surface and the counter-alignment surface interacting with one another in the sense of an alignment of the partition wall relative to the support ring and thus to the swirl chamber in the direction running horizontally in the operational orientation of the vortex throttle device.
  • the partition wall can be designed as a substantially flat plate with a circular aperture. However, it is also possible for the partition to have the shape of a more or less flat funnel or a flat bowl.
  • the partition wall can advantageously be replaced from the upper edge of the vortex chamber using a suitable tool.
  • the tool can be designed, for example, in such a way that it can grip behind the partition after passing through the diaphragm opening or, after insertion into the diaphragm opening, can be brought into holding engagement with its edge.
  • the vortex throttle device, in particular the diaphragm opening can also be cleaned from the upper edge of the vortex chamber. It is therefore not necessary to design the vortex chamber as an accessible shaft.
  • the housing comprises a first housing unit which has the wall delimiting the stilling chamber, the partition wall having the aperture or the support ring and that wall section of the wall delimiting the vortex chamber into which the liquid inlet opens, and a second housing unit which can be connected to the first housing unit in a liquid-tight manner.
  • the first housing unit forms the actual functional part, since it includes all the components required for the vortex throttle function, while the second housing unit only has the function of providing the vortex chamber height required for the maximum storage height provided on the inlet side. It is therefore possible, using one and the same first housing unit, to implement different installation depths, for example an installation depth of 6 m or more.
  • the second housing unit is tubular. In this case, you only need to cut an excessively long pipe to the length required for the respective installation depth.
  • the first housing unit can in this case be designed with a pipe socket into which the tubular second housing unit can be easily inserted for a sealing connection.
  • the first housing unit can furthermore have a connection piece serving to connect to a liquid inlet line and / or a connection piece serving to connect to a liquid discharge line, wherein it can preferably be formed in one piece with this or these connection pieces.
  • the first housing unit can be made as a plastic part, preferably made using the rotational molding or injection molding process, for example from HDPE or PP.
  • the second housing unit can be designed as a double-walled plastic tube, the outer tube of which is designed as a corrugated tube and the inner tube as a smooth tube.
  • the first housing unit has a lower part which includes the wall surrounding the stilling chamber, and an upper part which includes that wall section of the wall surrounding the vortex chamber into which the liquid inlet opens, the Partition wall or the support ring is held between the upper part and the lower part.
  • this type of holding the partition or the support ring can also be implemented if the vortex throttle device does not follow the design principle of separation into a first housing part, which includes all functional components, and a second housing part, which is only used to provide the required overall height is realized, namely in that the housing has a lower part, which includes the wall bordering the stilling chamber, and an upper part which includes the wall bordering the vortex chamber, the partition wall having the aperture or the support ring being held between the upper part and the lower part .
  • the upper part can be tubular, for example as a double-walled plastic tube, in particular with an outer corrugated tube and an inner smooth tube, and provided with the liquid inlet.
  • the height position of the lower edge of the liquid inlet from the height position of the upper surface of the partition wall is a distance of at most 100 mm, preferably at most 50 mm, particularly preferably at most 20 mm, the lower edge of the liquid inlet is more preferably arranged at the level of the upper surface of the partition wall.
  • the partition wall is arranged obliquely in the operational orientation of the vortex throttle device relative to the direction of the gravitational force, for example at a 45 ° angle. In this way, a smaller step in the sole between the liquid inlet and the liquid outlet can be provided.
  • the liquid inlet runs in a straight line over a predetermined distance before it flows into the vortex chamber, the predetermined distance preferably being at least 80 cm, more preferably at least 100 cm.
  • the vortex chamber in order to improve the formation of the vortex flow in the vortex chamber, it can also be advantageous for the vortex chamber to have a vortex core ventilation opening, preferably at its upper end in operational orientation.
  • a vortex core ventilation opening preferably at its upper end in operational orientation.
  • no such additional ventilation of the swirl chamber is necessary, since the swirl chamber cover does not form a tight seal to the surface.
  • the additional ventilation could take place, for example, via a pipe to the surface of the earth or via a line connection between the vortex chamber and the liquid drain.
  • the cross-sectional area of the liquid drain is larger than the cross-sectional area of the liquid inlet, wherein the ratio of the cross-sectional area of the liquid outlet to the cross-sectional area of the liquid inlet is preferably at least 1.2, more preferably at least 1.5.
  • the height of the vortex chamber is at least equal, preferably at least equal to twice, the square root of its taken at the level of the partition and in the operational position orthogonal to the direction of the Earth's gravitational pull, multiplied by a factor of 4 / ⁇ , is the cross-sectional area. If the vortex chamber has a circular disk-shaped cross-section, this value is equal to the diameter of the cross-sectional area. In the case of differently shaped cross-sectional areas, on the other hand, an “effective diameter” which is defined by the calculation rule mentioned and which is to be compared with the height of the vortex chamber results.
  • the square root of the ratio of the opening area of the diaphragm opening to that taken at the level of the partition wall and in the operational position orthogonal to the direction of the gravitational pull of the cross-sectional area of the vortex chamber between about 0.02 and about 0.65, preferably between about 0.08 and about 0.53.
  • an emergency overflow line opens into the vortex chamber at a predetermined distance above the partition wall.
  • this emergency overflow line is connected to the liquid drain and thus forms a bypass line bypassing the aperture.
  • water can enter the emergency overflow line and reach the liquid drain, bypassing the aperture.
  • the emergency overflow line is in fluid transfer connection with a storage volume arranged upstream of the vortex throttle device.
  • a storage volume arranged upstream of the vortex throttle device.
  • water can be introduced into the vortex chamber in such a way that it brings the vortex flow to a standstill.
  • the water can then pass through the entire opening area of the diaphragm opening, which results in a considerably lower throttling effect and thus a faster drainage of the water.
  • the level in the storage volume has dropped below the height corresponding to the predetermined distance again, water from the storage volume enters the vortex chamber again only through the liquid inlet, so that the vortex flow is set in motion again. Switching between vortex throttle mode and emergency overflow mode and back again to vortex throttle mode is therefore completely automatic.
  • the invention further relates to a combination of a vortex throttle device according to the invention with an upstream storage volume which is in fluid transfer connection with the vortex throttle device via the liquid inlet.
  • the storage volume can be used as open pond, as a retention channel, as an open or closed concrete basin or as an underground trench.
  • the trench can be composed of a plurality of trench elements, such as those from the EP 1 260 640 A1 or the DE 10 2011 086 016 A1 are known to the applicant.
  • FIG. 1 shows a first embodiment of the vortex throttle device 10 according to the invention in a schematic overall view.
  • the eddy throttle device 10 comprises a housing 20 with a first housing unit 22 and a second housing unit 24.
  • a partition wall 30 with a diaphragm opening 32 is arranged in the interior of the first housing unit 22.
  • the partition wall 30 divides the interior of the first housing unit 22 into a still chamber 40 and a vortex chamber 50.
  • the vortex chamber 50 is arranged above the partition wall 30, while the still chamber 40 is arranged below the partition wall 30.
  • a liquid inlet 80 is connected to the swirl chamber 50, and a liquid outlet 85 connects to the stilling chamber 40, which leads, for example, to a sewer system or to a body of water (both not shown).
  • the liquid inlet 80 is connected to the first housing unit 22 in such a way that inflowing water flows essentially tangentially into the swirl chamber 50 (see FIG Figure 3 ). Due to the essentially tangential inflow of the water, a vortex flow forms in the vortex chamber 50. In Figure 1 the surface of the vortex 34 which forms due to this vortex flow is indicated by dashed lines. Since the air core 36 of this vortex 34 extends into the aperture 32 of the partition 30 continues into it, the cross-sectional area occupied by the air core 36 reduces the cross-section of the diaphragm opening 32 available for the passage of water, which increases the throttling effect of the diaphragm opening 32.
  • the inflow direction of the water from the liquid inlet 80 into the swirl chamber 50 is essentially orthogonal to the central axis A of the swirl chamber 50 (see FIG Figure 1 ), which extends essentially parallel to the direction G of the gravitational force.
  • the wall of the housing 20 surrounding the vortex chamber 50 is preferably designed to be rotationally symmetrical.
  • the central axis A thus also represents the rotational symmetry axis of the vortex chamber 50.
  • the second housing unit 24 is designed as a double-walled tube 70 with an inner smooth tube 71 and an outer corrugated tube 72.
  • the inner smooth tube 71 of the second housing unit 24 preferably has essentially the same inner diameter as the swirl chamber 50 at its transition to the second housing unit 24.
  • the second housing unit 24 thus extends the first housing unit 22 or its vortex chamber 50 from its position in the ground 90 to a terrain surface 92.
  • the pipe 70 can pass through a manhole cover 75 be covered. If the closure of the manhole cover 75 with the pipe 70 is so tight that a sufficient supply of air to the air core 36 of the vortex 34 cannot be ensured, an additional ventilation opening 78 can be provided in the manhole cover 75.
  • central axis A of the swirl chamber 50 and the central axis of the inner smooth tube 71 essentially coincide. If the inner smooth tube 71 has a circular disk-shaped cross section, which is preferred, the central axis A can at the same time also represent the rotational symmetry axis of the inner smooth tube 71.

  • the first housing unit 22 is formed with a bead 22a, which serves as a support surface on which the support ring 60 is placed immediately after the first housing unit 22 has been manufactured, ie as long as the plastic of the first housing unit 22 has not yet cooled completely. When it cools down, the plastic of the first housing unit 22 contracts slightly and surrounds the edge of the support ring 60 to form a bead 22b.
  • a plastic weld seam 22c can also be provided in order to secure the support ring 60 on the first housing unit 22.
