Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft einen Umlenkbogen zur Umlenkung von einem AbwasserstromThe present invention relates to a deflection bend for deflecting a waste water flow

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik sind Umlenkbogen bekannt geworden. Bei Abwasserleitungen sind Umlenkbogen typischerweise ein limitierender Faktor bezüglich der Abflussleistung, weil eine Schichtströmung in einem in einem im Wesentlichen in der Horizontalen verlaufenden Rohr in eine vertikale Ringströmung in einem in der Vertikalen verlaufenden Rohr umgewandelt werden muss. Bei einem herkömmlichen Rohrbogen treten grosse Strömungsverluste auf, was die Wahl eines grösseren Durchmessers voraussetzt. Rohrförmige Formstücke als Teil von einem komplexen System von Rohren sind z.B. im Dokument US1197395 , US1186280 oder DE2414130 offenbart.Deflection bends have become known from the prior art. In sewer pipes, deflection bends are typically a limiting factor with regard to the discharge capacity, because a stratified flow in a pipe running essentially in the horizontal direction has to be converted into a vertical ring flow in a pipe running in the vertical plane. With a conventional pipe bend, large flow losses occur, which requires the selection of a larger diameter. For example, tubular fittings as part of a complex system of pipes are in the document US1197395 , US1186280 or DE2414130 disclosed.

Insbesondere offenbart die US 1197395 ein Rohrstück mit einem Hauptrohrabschnitt und einem seitlichen Rohrabschnitt, der in den Hauptrohrabschnitt mündet, wobei der seitliche Rohrabschnitt einen Krümmungsreich aufweist.In particular, the US 1197395 a pipe section with a main pipe section and a lateral pipe section which opens into the main pipe section, the lateral pipe section having a region of curvature.

DARSTELLUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION

Die Aufgabe der vorliegenden Erfindung ist es, ein Umlenkbogen anzugeben, der eine verbesserte Abflussleistung aufweist.The object of the present invention is to specify a deflection bend which has an improved drainage capacity.

Diese Aufgabe löst der Umlenkbogen nach Anspruch 1. Demgemäss umfasst ein Umlenkbogen zur Führung von Abwasser

  • einen ersten Rohrleitungsabschnitt, der sich entlang einer ersten als Gerade ausgebildeten Leitlinie erstreckt,
  • einen zweiten Rohrleitungsabschnitt, der sich entlang einer zweiten als Gerade ausgebildeten Leitlinie erstreckt, und einen Umlenkabschnitt, welcher den ersten Rohrleitungsabschnitt mit dem zweiten Rohrleitungsabschnitt verbindet, wobei sich der Umlenkabschnitt entlang dritten Leitlinie erstreckt, welche dritte Leitlinie die erste Leitlinie mit der zweiten Leitlinie verbindet.
This object is achieved by the deflecting bend according to claim 1. Accordingly, it comprises a deflecting bend for guiding waste water
  • a first pipeline section which extends along a first guideline formed as a straight line,
  • a second pipeline section, which extends along a second guideline formed as a straight line, and a deflection section which connects the first pipeline section to the second pipeline section, wherein the deflection section connects extends along third guideline, which third guideline connects the first guideline to the second guideline.

Die erste Leitlinie des ersten Rohrleitungsabschnittes steht in einem Neigungswinkel im Bereich von 90° bis 100° zur zweiten Leitlinie des zweiten Rohrleitungsabschnittes. Die erste und die zweite Leitlinie spannen eine Vertikalebene auf.The first guideline of the first pipe section is at an angle of inclination in the range from 90 ° to 100 ° to the second guideline of the second pipe section. The first and the second guideline span a vertical plane.

Eine Neigungsebene ist durch die erste Leitlinie und eine Referenzachse, aufgespannt. Die Referenzachse schneidet die erste Leitlinie rechtwinklig und liegt rechtwinklig zur zweiten Leitlinie und rechtwinklig zur Vertikalebene.An inclination plane is spanned by the first guideline and a reference axis. The reference axis intersects the first guideline at right angles and is at right angles to the second guideline and at right angles to the vertical plane.

Der Umlenkabschnitt wird aus mehreren Teilabschnitten gebildet, welche Teilabschnitte jeweils zugeordnete Leitlinienabschnitte der dritten Leitlinie aufweisen. Mindestens einer der Teilabschnitte erlaubt das Auslenken der Leitlinie des Umlenkabschnittes aus der besagten Vertikalebene hinaus. Die Auslenkung ist derart, dass das Abwasser aus dem ersten Rohrleitungsabschnitt beim Durchströmen des besagten Teilabschnittes in Rotation um die dritte Leitlinie versetzt wird und in Rotation dem zweiten Rohrleitungsabschnitt zuleitbar ist.The deflection section is formed from several subsections, which subsections each have assigned guideline sections of the third guideline. At least one of the subsections allows the guideline of the deflection section to be deflected out of said vertical plane. The deflection is such that the wastewater from the first pipeline section is set in rotation about the third guideline as it flows through said subsection and can be fed to the second pipeline section in rotation.

Durch die Auslenkung kann das Abwasser in eine gezielte und kontrollierte Rotation versetzt werden, so dass das Abwasser entlang den Wänden des zweiten Rohrleitungsabschnittes rotiert und in Rotation einer sich dem zweiten Rohrleitungsabschnitt anschliessenden Rohr überführt werden. Durch das kontrollierte Versetzen des Abwasserstroms in Rotation kann die Abflussleistung des Umlenkbogens erhöht werden.As a result of the deflection, the wastewater can be set in a targeted and controlled rotation, so that the wastewater rotates along the walls of the second pipe section and is transferred into rotation of a pipe adjoining the second pipe section. The controlled setting of the wastewater flow in rotation can increase the discharge capacity of the deflection bend.

Die hierin genannten Leitlinien sind als geometrische Leitlinien zu verstehen, wobei die entsprechenden Abschnitte, also der erste Rohrleitungsabschnitt, der Umlenkabschnitt und der zweite Rohrleitungsabschnitt, geometrisch entlang dieser Leitlinien extrudiert werden. Das heisst, die Abschnitte erstrecken sich entlang dieser Leitlinien im Sinne der geometrischen Extrusion. Die Leitlinien liegen vorzugsweise im Inneren von den beiden Rohrleitungsabschnitten und vom Umlenkabschnitt.The guidelines mentioned herein are to be understood as geometric guidelines, the corresponding sections, that is to say the first pipeline section, the deflection section and the second pipeline section, being extruded geometrically along these guidelines. This means that the sections extend along these guidelines in the sense of geometric extrusion. The guidelines are preferably located in the interior of the two pipeline sections and of the deflection section.

Vorzugsweise ist der Umlenkabschnitt derart ausgebildet ist, dass das durch den Umlenkabschnitt fliessende Abwasser eine Rotation um eine Richtung erfährt, welche zu der Richtung der erstmaligen Umlenkung durch den Umlenkabschnitt identisch ist.The deflection section is preferably designed in such a way that the waste water flowing through the deflection section experiences a rotation about a direction which is identical to the direction of the first deflection by the deflection section.

Hierdurch wird eine zweifache Umlenkung im Wesentlichen unterbunden, was geringere Strömungsverluste bedeutet.This essentially prevents a double deflection, which means lower flow losses.

Erfolgt die Auslenkung in Richtung der ersten Leitlinie des ersten Rohrleitungsabschnittes gesehen von der Vertikalebene nach links, so wird eine Rotation in Richtung links bzw. im Gegenuhrzeigersinn um die Leitlinie erzielt.If the deflection takes place in the direction of the first guideline of the first pipeline section, seen from the vertical plane to the left, then a rotation in the direction to the left or counterclockwise around the guideline is achieved.

Erfolgt die Auslenkung in Richtung der ersten Leitlinie des ersten Rohrleitungsabschnittes gesehen von der Vertikalebene nach rechts, so wird eine Rotation in Richtung rechts bzw. im Uhrzeigersinn um die Leitlinie erzielt.If the deflection takes place in the direction of the first guideline of the first pipeline section, seen from the vertical plane to the right, a rotation in the direction to the right or clockwise around the guideline is achieved.

Das heisst, zwischen dem ersten Rohrleitungsabschnitt und dem zweiten Rohrleitungsabschnitt sind ausschliesslich die genannten drei Teilabschnitte in der entsprechenden Reihenfolge vorhanden.The deflection section particularly preferably consists of the three named subsections. That is, between the first pipeline section and the second pipeline section, only the three subsections mentioned are present in the corresponding order.

Der Querschnitt der beiden Rohrleitungsabschnitte ist vorzugsweise kreisförmig mit einem konstanten Durchmesser. Das heisst, die beiden Rohrleitungsabschnitte erstrecken sich kreiszylindrisch entlang der beiden Leitlinien. Die Leitlinien sind dabei die Mittelachsen der beiden Rohrleitungsabschnitte.The cross section of the two pipeline sections is preferably circular with a constant diameter. This means that the two pipeline sections extend in a circular-cylindrical manner along the two guidelines. The guidelines are the central axes of the two pipe sections.

Der Querschnitt des Umlenkabschnittes kann verschiedenartig ausgebildet sein.The cross section of the deflecting section can be designed in various ways.

In einer ersten Variante verläuft der Querschnitt des Umlenkabschnittes im Wesentlichen konstant kreisförmig und entspricht dem Querschnitt der beiden Rohrleitungsabschnitte entspricht, wobei die Leitlinie auf der mittig durch die Abschnitte verlaufenden Mittellinie verläuft.In a first variant, the cross section of the deflection section runs essentially constant circular and corresponds to the cross section of the two pipeline sections, the guideline on the center line running centrally through the sections runs.

In einer zweiten Variante ist der Querschnitt des Umlenkabschnittes abschnittsweise durch eine Querschnittsvergrösserung vergrössert, derart dass die Querschnittsfläche des Umlenkabschnittes bezüglich des ersten bzw. des zweiten Rohrleitungsabschnittes vergrössert wird.In a second variant, the cross-section of the deflection section is enlarged in sections by an increase in cross-section, such that the cross-sectional area of the deflection section is enlarged with respect to the first and the second pipeline section.

This means that the position of the third guideline extends through the geometric centers of the original circular cross-section. The third guideline is made up of the corresponding guideline sections, depending on the existence of the individual subsections of the deflection section.

Vorzugsweise vergrössert die Querschnittsvergrösserung den Radius des kreisförmigen Querschnittes um 5% bis 20% oder um 10% bis 20%.Preferably, the cross-sectional enlargement increases the radius of the circular cross-section by 5% to 20% or by 10% to 20%.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

Unter Bezugnahme auf die Figuren wird in der Folge eine Ausführungsform eines Umlenkbogens beschrieben.An embodiment of a deflection bend is described below with reference to the figures.

Der in den Figuren gezeigte Umlenkbogen dient der Umlenkung eines Abwasserstrahles A in einem Fallleitungssystem bzw. in einem Fallleitungsverzug. Abwasser A wird dem Umlenkbogen in der Horizontalen H zugeführt und wird dann durch den Umlenkbogen in die Vertikale V umgelenkt. Das Abwasser A tritt über den ersten Rohrleitungsabschnitt 1 in den Umlenkbogen ein, passiert sodann den Umlenkabschnitt 3 und wir dann dem zweiten Rohrleitungsabschnitt 2, über welchen das Abwasser den Umlenkbogen wieder verlässt, zugeleitet. Der Umlenkbogen ist dabei derart ausgebildet, dass das Wasser in Rotation an der Innenwand 15 des Umlenkbogens versetzt wird.The deflection bend shown in the figures serves to deflect a wastewater jet A in a downpipe system or in a downpipe delay. Wastewater A is fed to the deflection bend in the horizontal H and is then deflected into the vertical V by the deflection bend. The waste water A enters the deflection bend via the first pipe section 1, then passes the deflection section 3 and then the second pipe section 2, via which the waste water passes the deflection bend again leaves, forwarded. The deflection bend is designed in such a way that the water is set in rotation on the inner wall 15 of the deflection bend.

Der Umlenkbogen umfasst einen ersten Rohrleitungsabschnitt 1, einen Umlenkabschnitt 3 und einen zweiten Rohrleitungsabschnitt 2. Dem ersten Rohrleitungsabschnitt 1 schliesst sich unmittelbar und direkt der Umlenkabschnitt 3 und dem Umlenkabschnitt 3 schliesst sich unmittelbar und direkt der zweite Rohrleitungsabschnitt 2 an. Der Umlenkabschnitt 3 verbindet also den ersten Rohrleitungsabschnitt 1 mit dem zweiten Rohrleitungsabschnitt 2.The deflection bend comprises a first pipe section 1, a deflection section 3 and a second pipe section 2. The first pipe section 1 is directly and directly connected to the deflection section 3 and the deflection section 3 is immediately and directly connected to the second pipe section 2. The deflection section 3 thus connects the first pipeline section 1 to the second pipeline section 2.

Der erste Rohrleitungsabschnitt 1 erstreckt sich entlang einer ersten als Gerade ausgebildeten Leitlinie L1. Der zweite Rohrleitungsabschnitt 2 erstreckt sich entlang einer zweiten ebenfalls als Gerade ausgebildeten Leitlinie L2. Der Umlenkabschnitt 3 erstreckt sich entlang einer dritten Leitlinie L3, welche dritte Leitlinie L3 die erste Leitlinie L1 mit der zweiten Leitlinie L2 verbindet.The first pipeline section 1 extends along a first guideline L1 designed as a straight line. The second pipeline section 2 extends along a second guideline L2, which is also designed as a straight line. The deflection section 3 extends along a third guideline L3, which third guideline L3 connects the first guideline L1 with the second guideline L2.

Die hierin genannten Leitlinien L1, L2, L3 bzw. die Abschnitte L4, L5, L6 der Leitlinie L3 sind als geometrische Leitlinien zu verstehen, wobei sich der erste Rohrleitungsabschnitt 1, der Umlenkabschnitt 3 und der zweite Rohrleitungsabschnitt 2 geometrisch entlang dieser Leitlinien extrudiert werden. Das heisst, die Abschnitte 1, 2, 3 erstrecken sich entlang dieser Leitlinien im Sinne der geometrischen Extrusion.The guidelines L1, L2, L3 mentioned herein or the sections L4, L5, L6 of the guideline L3 are to be understood as geometric guidelines, the first pipeline section 1, the deflection section 3 and the second pipeline section 2 being extruded geometrically along these guidelines. That is, the sections 1, 2, 3 extend along these guidelines in the sense of geometric extrusion.

Die erste Leitlinie L1 und die zweite Leitlinie L2 spannen eine Vertikalebene VE auf. Die Vertikalebene VE ist beispielsweise in der Figur 5a eingezeichnet. Die Vertikalebene VE geht dabei geometrisch gesehen durch die erste Leitlinie L1 und die zweite Leitlinie L2.The first guideline L1 and the second guideline L2 span a vertical plane VE. The vertical plane VE is for example in the Figure 5a drawn. From a geometrical perspective, the vertical plane VE passes through the first guideline L1 and the second guideline L2.

Die erste Leitlinie L1 des ersten Rohrleitungsabschnittes 1 steht in einem Neigungswinkel Δ im Bereich von 90° bis 100° zur zweiten Leitlinie L2 des zweiten Rohrleitungsabschnittes 2. In Einbaulage liegt die zweite Leitlinie L2 im Wesentlichen in der Vertikalen und die ersten Leitlinie L1 steht je nach Winkel Δ in der Horizontalen oder zur Horizontalen winklig geneigt.The first guideline L1 of the first pipe section 1 is at an angle of inclination Δ in the range from 90 ° to 100 ° to the second guideline L2 of the second pipe section 2. In the installed position, the second guideline L2 is essentially vertical and the first guideline L1 is depending on Angle Δ in the horizontal or inclined at an angle to the horizontal.

Eine Neigungsebene NE wird durch die erste Leitlinie L1 und eine Referenzachse R aufgespannt. Die Referenzachse R schneidet die erste Leitlinie L1 rechtwinklig und steht rechtwinklig zur zweiten Leitlinie L2 und rechtwinklig zur Vertikalebene VE.An inclination plane NE is defined by the first guideline L1 and a reference axis R. stretched. The reference axis R intersects the first guideline L1 at right angles and is at right angles to the second guide line L2 and at right angles to the vertical plane VE.

Der Umlenkabschnitt 3 wird aus mehreren Teilabschnitten gebildet. Die Teilabschnitte tragen in den Figuren die Bezugszeichen 4, 5, 6. Jeder der Teilabschnitte 4, 5, 6 weist eine jeweils dem Teilabschnitt 4, 5, 6 zugeordnete Leitlinienabschnitt L4, L5, L6 auf. Die Leitlinienabschnitte L4, L5, L6 sind dabei Teil der dritten Leitlinie L3, entlang welcher es sich der Umlenkabschnitt 3 erstreckt. Die dritte Leitlinie L3 wird demnach durch die die Leitlinienabschnitte L4, L5, L6 definiert.The deflection section 3 is formed from a plurality of subsections. The subsections in the figures bear the reference numerals 4, 5, 6. Each of the subsections 4, 5, 6 has a guideline section L4, L5, L6 assigned to the subsection 4, 5, 6. The guideline sections L4, L5, L6 are part of the third guideline L3, along which the deflecting section 3 extends. The third guideline L3 is accordingly defined by the guideline sections L4, L5, L6.

Mindestens einer der Teilabschnitte 4, 5, 6 ist dabei derart ausgebildet, dass dieser das Auslenken der Leitlinie L3 des Umlenkabschnittes 3 aus der besagten Vertikalebene VE erlaubt. Die Auslenkung ist dabei derart, dass das Abwasser A aus dem ersten Rohrleitungsabschnitt 1 beim Durchströmen des besagten Teilabschnittes 4, 5, 6 in Rotation um die dritte Leitlinie L3 herum versetzt wird und in Rotation dem zweiten Rohrleitungsabschnitt 2 zuleitbar ist.At least one of the subsections 4, 5, 6 is designed in such a way that it allows the guideline L3 of the deflection section 3 to be deflected from the said vertical plane VE. The deflection is such that the wastewater A from the first pipe section 1 is set in rotation around the third guideline L3 as it flows through the said subsection 4, 5, 6 and can be fed to the second pipe section 2 in rotation.

Diese Rotation wird in den Figuren 4a und 4b veranschaulicht. Das Abwasser mit dem Bezugszeichen A fliesst im ersten Rohrleitungsabschnitt 1 im Wesentlichen als horizontale Schichtströmung in Richtung des Umlenkabschnittes 3. Unter einer schichtströmung wird verstanden, dass im unteren Bereich des ersten Rohrleitungsabschnittes 1 Wasser und ggf. Feststoffe flies sen, während im oberen Bereich Luft ist. Die Strömung wird durch die Strömungslinien AS dargestellt. Sobald nun das Abwasser A auf den Umlenkabschnitt 3 auftritt, wird das Abwasser A durch mindestens einen der Teilabschnitte 4, 5, 6 aus der Vertikalebene VE weggeführt. Das Abwasser A wird also umgelenkt, derart, dass eine Rotation um die Leitlinie L3 des Umlenkabschnittes 3 resultiert. Das Abwasser A wird im Umlenkabschnitt 3 in Rotation versetzt und dann ebenfalls in Rotation dem zweiten Rohrleitungsabschnitt 2 zugeleitet.This rotation is in the Figures 4a and 4b illustrated. The wastewater with the reference symbol A flows in the first pipe section 1 essentially as a horizontal stratified flow in the direction of the deflection section 3. A stratified flow is understood to mean that water and possibly solids flow in the lower area of the first pipeline section 1, while there is air in the upper area . The flow is represented by the flow lines AS. As soon as the wastewater A occurs on the deflection section 3, the wastewater A is led away from the vertical plane VE through at least one of the subsections 4, 5, 6. The wastewater A is thus deflected in such a way that a rotation about the guideline L3 of the deflection section 3 results. The wastewater A is set in rotation in the deflection section 3 and then also fed to the second pipeline section 2 in rotation.

Der Umlenkabschnitt 3 ist dabei derart ausgebildet, dass das durch den Umlenkabschnitt 3 fliessende Abwasser A eine Rotation in eine Richtung erfährt, welche mit der Richtung der erstmaligen Umlenkung durch den Umlenkabschnitt 3 identisch ist.The deflection section 3 is designed in such a way that the waste water A flowing through the deflection section 3 experiences a rotation in a direction which is identical to the direction of the first deflection by the deflection section 3.

In der gezeigten Ausführungsform der Figuren 4a/4b wird das Abwasser in Fliessrichtung entlang der ersten Leitlinie L1 gesehen nach links umgeleitet. Die Rotation erfolgt dann ebenfalls in die gleiche Richtung, nämlich im Gegenuhrzeigersinn um die Leitlinien L3, L2. Die Richtung "Links" wird in der Figur 4a durch den Pfeil links symbolisiert. Die Richtung der Rotation im Gegenuhrzeigersinn wird durch das Bezugszeichen GUZ dargestellt.In the embodiment shown, the Figures 4a / 4b the wastewater is diverted to the left as seen in the direction of flow along the first guideline L1. The rotation then also takes place in the same direction, namely counterclockwise around the guidelines L3, L2. The "Left" direction is in the Figure 4a symbolized by the arrow on the left. The counterclockwise direction of rotation is represented by the reference symbol GUZ.

Durch die Tatsache, dass das durch den Umlenkabschnitt 3 fliessende Abwasser A eine Rotation um eine Richtung erfährt, welche zu der Richtung der erstmaligen Umlenkung durch den Umlenkabschnitt 3 identisch ist, ergeht der Vorteil, dass eine weitere Umlenkung des Abwassers A vermieden werden kann. Insofern ist dies strömungstechnisch von grossem Vorteil, weil weitere Verluste, welche durch eine erneute Umlenkung verursacht werden, vermieden werden können.The fact that the waste water A flowing through the deflection section 3 is rotated about a direction which is identical to the direction of the first deflection by the deflection section 3 results in the advantage that a further deflection of the waste water A can be avoided. In this respect, this is of great advantage in terms of flow technology, because further losses, which are caused by a renewed deflection, can be avoided.

Der besagte Teilabschnitt 4, 5, 6, der das Auslenken der Leitlinie L3 des Umlenkabschnittes 3 seitlich aus der besagten Vertikalebene VE erlaubt, ist zudem aus der Neigungsebene NE in Richtung des zweiten Rohrleitungsabschnittes 2 ausgelenkt. Diese Auslenkung wird in den Figuren 6a bis 6d gezeigt. Die Auslenkung ist dabei derart, dass der Endpunkt der Leitlinie L4 des besagten Teilabschnittes 4 ausgehend von der Neigungsebene NE unterhalb der Neigungsebene NE in Richtung des zweiten Rohrleitungsabschnittes 2 zu liegen kommt.Said subsection 4, 5, 6, which allows the guideline L3 of the deflecting section 3 to be deflected laterally out of the said vertical plane VE, is also deflected from the inclination plane NE in the direction of the second pipe section 2. This deflection is in the Figures 6a to 6d shown. The deflection is such that the end point of the guideline L4 of said subsection 4, starting from the inclination plane NE, comes to lie below the inclination plane NE in the direction of the second pipeline section 2.

Der besagte mindestens einen Teilabschnitt 4, 5 ,6, der das Auslenken der Leitlinie L3 des Umlenkabschnittes 3 aus der besagten Vertikalebene VE erlaubt, ist vorzugsweise ein erster Teilabschnitt 4 in der Gestalt eines Rohrbogens 8.Said at least one section 4, 5, 6, which allows the guiding line L3 of the deflection section 3 to be deflected from the said vertical plane VE, is preferably a first section 4 in the form of a pipe bend 8.

Anhand der Figuren 5a bis 6d wird die geometrische Ausbildung des Rohrbogens 8 in der Folge genauer erläutert. Der Rohrbogen 8 erstreckt sich entlang einer kreisbogenförmigen Leitlinie L4. Die kreisförmige Leitlinie L4 des Rohrbogens 8 erstreckt sich tangential zur ersten Leitlinie L1 des ersten Rohrleitungsabschnittes 1. Das heisst, die Leitlinie L4 schliesst sich tangential der ersten Leitlinie L1 an.Based on Figures 5a to 6d the geometric design of the pipe bend 8 is explained in more detail below. The pipe bend 8 extends along an arcuate guideline L4. The circular guideline L4 of the pipe bend 8 extends tangentially to the first guideline L1 of the first pipeline section 1. That is, the guideline L4 connects tangentially to the first guideline L1.

Der Endbereich 1b des ersten Rohrleitungsabschnittes 1 und der Anfangsbereich 8a des besagten Rohrbogens 8 liegen in einer Bezugsebene BE. Die Bezugsebene BE ist dabei eine geometrische Bezugsebene. Je nach Ausbildung des Querschnittes des Umlenkabschnittes 3 liegen allenfalls nur Teile des Endbereichs 1b bzw. des Anfangsbereichs 8a auf der Bezugsebene BE. Die Bezugsebene BE liegt parallel und beabstandet zu einer ersten Referenzebene RE. Die Referenzebene RE wird durch die Stirnseite 1a des ersten Rohrleitungsabschnittes aufgespannt und steht rechtwinklig zur ersten Leitlinie L1.The end area 1b of the first pipe section 1 and the starting area 8a of the said pipe bend 8 lie in a reference plane BE. The reference plane BE is a geometric reference plane. Depending on the design of the cross section of the deflecting section 3, only parts of the end region 1b or of the starting region 8a lie on the reference plane BE. The reference plane BE lies parallel to and at a distance from a first reference plane RE. The reference plane RE is spanned by the end face 1a of the first pipe section and is at right angles to the first guideline L1.

In der gezeigten Ausführungsform liegt die kreisbogenförmige Leitlinie L4 in einer Bezugsebene E8. Das heisst, dass sich die kreisbogenförmige Leitlinie L4 in der Bezugsebene E8 erstreckt bzw. dass die kreisbogenförmige Leitlinie L4 die Bezugsebene E8 aufspannt. Die Bezugsebene E8 ist bezüglich der Neigungsebene NE um einen Schwenkwinkel α8 von 10° bis 70°, hier von 30° um die erste Leitlinie L1 zum zweiten Rohrleitungsabschnitt 2 hin verschwenkt. Weiter weist der Rohrbogen 8 einen Bogenwinkel β8 von 10° bis 80°, hier von 30°, auf. Unter dem Bogenwinkel β8 wird in diesem Zusammenhang verstanden, dass der Rohrbogen 8 und seine Leitlinie L4 sich über einen Öffnungswinkel erstrecken.In the embodiment shown, the circular arc-shaped guideline L4 lies in a reference plane E8. This means that the circular arc-shaped guideline L4 extends in the reference plane E8 or that the circular arc-shaped guideline L4 spans the reference plane E8. The reference plane E8 is pivoted with respect to the inclination plane NE by a pivot angle α8 of 10 ° to 70 °, here by 30 ° around the first guideline L1 to the second pipe section 2. The pipe bend 8 also has a bend angle β8 of 10 ° to 80 °, here of 30 °. In this context, the bend angle β8 is understood to mean that the pipe bend 8 and its guide line L4 extend over an opening angle.

In einer alternativen in den Figuren nicht gezeigten Ausführungsform wäre es auch denkbar, dass der Rohrbogen nur um den Schwenkwinkel β8 verschwenkt ist und einen anderen Bogenwinkel aufweist, oder dass der Rohrbogen nur den besagten Bogenwinkel α8 aufweist, aber nicht um den Schwenkwinkel α8 verschwenkt ist.In an alternative embodiment not shown in the figures, it would also be conceivable that the pipe bend is pivoted only by the pivot angle β8 and has a different bend angle, or that the pipe bend only has the said bend angle α8, but is not pivoted by the pivot angle α8.

In der gezeigten Ausführungsform schliesst sich dem ersten Teilabschnitt 4 ein zweiter Teilabschnitt 5 an. Unter Bezugnahme auf die Figuren 7a bis 7d wird die geometrische Ausbildung des zweiten Teilabschnittes 5 genauer erläutert.In the embodiment shown, the first section 4 is followed by a second section 5. With reference to the Figures 7a to 7d the geometric design of the second section 5 is explained in more detail.

Der zweite Teilabschnitt 5 hat die Gestalt eines zweiten Rohrbogens 9, der sich entlang einer kreisbogenförmigen Leitlinie L5 erstreckt. Die kreisbogenförmige Leitlinie L5 des zweiten Rohrbogens 9 schliesst sich tangential der kreisbogenförmigen Leitlinie L4 des ersten Rohrbogens 8 an.The second section 5 has the shape of a second pipe bend 9 which extends along a circular arc-shaped guideline L5. The arcuate guideline L5 of the second pipe bend 9 adjoins the arcuate guide line L4 of the first pipe bend 8 tangentially.

In der gezeigten Ausführungsform liegt die kreisbogenförmige Leitlinie L5 in einer Bezugsebene E9. Das heisst, dass sich die kreisbogenförmige Leitlinie L5 in der Bezugsebene E9 erstreckt bzw. dass die kreisbogenförmige Leitlinie L5 die Bezugsebene E9 aufspannt.In the embodiment shown, the arcuate guideline L5 lies in one Reference plane E9. This means that the circular arc-shaped guideline L5 extends in the reference plane E9 or that the circular arc-shaped guideline L5 spans the reference plane E9.

Die Bezugsebene E9 ist bezüglich der Bezugsebene E8 des ersten Rohrbogens 8 um einen Schwenkwinkel β9 von 10° bis 80°, insbesondere von 75°, um eine in der besagten Bezugsebene E8 und tangential zur kreisbogenförmigen Leitlinie L8 des ersten Rohrbogens 8 verlaufende Schwenkachse S9 zum zweiten Rohrleitungsabschnitt 2 hin verschwenkt. Die besagte Referenzebene R9 wird durch den Endbereich 8b des ersten Rohrbogens 8 aufgespannt. Die kreisbogenförmige Leitlinie L8 des ersten Rohrbogens 8 trifft rechtwinklig auf die Referenzebene R9 auf.The reference plane E9 is with respect to the reference plane E8 of the first pipe bend 8 by a pivot angle β9 of 10 ° to 80 °, in particular of 75 °, about a pivot axis S9 running in the said reference plane E8 and tangential to the circular arc-shaped guide line L8 of the first pipe bend 8 to the second Pipeline section 2 pivoted towards. Said reference plane R9 is spanned by the end region 8b of the first pipe bend 8. The circular arc-shaped guideline L8 of the first pipe bend 8 meets the reference plane R9 at right angles.

Weiter weist der zweite Rohrbogen 9 einen Bogenwinkel β9 von 45° bis 90°, hier von 72°, auf. Unter dem Bogenwinkel β9 wird in diesem Zusammenhang verstanden, dass der Rohrbogen 9 und seine Leitlinie L5 sich über einen Öffnungswinkel erstrecken.The second pipe bend 9 also has a bend angle β9 of 45 ° to 90 °, here of 72 °. In this context, the bend angle β9 is understood to mean that the pipe bend 9 and its guide line L5 extend over an opening angle.

Der Endbereich 9b des zweiten Rohrbogens 9 des zweiten Teilabschnittes 5 liegt in einer Ebene E9'. Die Ebene E9' verläuft im Wesentlichen rechtwinklig zur Vertikalebene VE. Die Ebene E9' liegt vorzugsweise näher zum ersten Rohrleitungsabschnitt 1 als zum zweiten Rohrleitungsabschnitt 2 liegt. Das heisst, die beiden Rohrbogen 8, 9 liegen in der ersten Hälfte der Gesamtlänge der Leitlinie L3 durch den Umlenkabschnitt.The end region 9b of the second pipe bend 9 of the second subsection 5 lies in a plane E9 '. The plane E9 'runs essentially at right angles to the vertical plane VE. The plane E9 ′ is preferably closer to the first pipe section 1 than to the second pipe section 2. This means that the two pipe bends 8, 9 lie in the first half of the total length of the guideline L3 through the deflection section.

Dem zweiten Teilabschnitt schliesst sich ein dritter Teilabschnitt 6 an. Unter Bezugnahme auf die Figuren 8a bis 8c wird der geometrische Aufbau des dritten Teilabschnittes erläutert. Der dritte Teilabschnitt 6 stellt eine Verbindung zwischen dem zweiten Teilabschnitt 5 und dem zweiten Rohrleitungsabschnitt 2 bereit.The second subsection is followed by a third subsection 6. With reference to the Figures 8a to 8c the geometrical structure of the third section is explained. The third subsection 6 provides a connection between the second subsection 5 and the second pipeline section 2.

Der dritte Teilabschnitt 6 erstreckt sich entlang einer Leitlinie L6. Die Leitlinie L6 ist ein Polynomzug, welcher sich tangential der Leitlinie L5 des zweiten Teilabschnittes 5 anschliesst und welcher tangential auf die Leitlinie L2 des zweiten Rohrleitungsabschnittes 2 auftrifft.The third subsection 6 extends along a guideline L6. The guideline L6 is a polynomial train which tangentially connects to the guideline L5 of the second subsection 5 and which meets the guideline L2 of the second pipeline section 2 tangentially.

Bei den drei Teilabschnitten 4, 5, 6 setzt sich die Leitlinie L3 des Umlenkabschnittes aus den drei Leitlinienabschnitten L4, L5, L6 zusammen.In the case of the three subsections 4, 5, 6, the guideline L3 of the deflection section is exposed the three guideline sections L4, L5, L6 together.

Besonders bevorzugt besteht der Umlenkabschnitt aus den drei genannten Teilabschnitten. Das heisst, zwischen dem ersten Rohrleitungsabschnitt und dem zweiten Rohrleitungsabschnitt sind ausschliesslich die genannten drei Teilabschnitte in der entsprechenden Reihenfolge vorhanden.The deflection section particularly preferably consists of the three named subsections. That is, between the first pipeline section and the second pipeline section, only the three subsections mentioned are present in the corresponding sequence.

Der Querschnitt der beiden Rohrleitungsabschnitte 1, 2 ist vorzugsweise kreisförmig mit einem konstanten Durchmesser. Das heisst, die beiden Rohrleitungsabschnitte 1, 2 erstrecken sich kreiszylindrisch entlang der beiden Leitlinien L1, L2. Die Leitlinien L1, L2 sind dabei die Mittelachsen der beiden Rohrleitungsabschnitte 1, 2.The cross section of the two pipeline sections 1, 2 is preferably circular with a constant diameter. This means that the two pipeline sections 1, 2 extend in a circular-cylindrical manner along the two guidelines L1, L2. The guidelines L1, L2 are the central axes of the two pipeline sections 1, 2.

Der Querschnitt des Umlenkabschnittes 3 kann verschiedenartig ausgebildet sein.The cross section of the deflection section 3 can be designed in various ways.

In einer ersten Variante ist der Querschnitt des Umlenkabschnittes 3 im Wesentlichen konstant kreisförmig und entspricht im Wesentlichen dem Querschnitt der beiden Rohrleitungsabschnitte 1, 2. Die Leitlinie L3 verläuft auf der mittig durch den Umlenkabschnitt 3 verlaufenden Mittellinie. Das heisst die Leitlinie L3 erstreckt sich durch die geometrischen Mittelpunkte des Umlenkabschnittes 3.In a first variant, the cross section of the deflection section 3 is essentially constant circular and essentially corresponds to the cross section of the two pipeline sections 1, 2. The guideline L3 runs on the center line running centrally through the deflection section 3. This means that the guideline L3 extends through the geometric center points of the deflection section 3.

In einer zweiten Variante, welche in den Figuren gezeigt ist, ist der Querschnitt des Umlenkabschnittes 3 abschnittsweise durch eine Querschnittsvergrösserung 13 vergrössert. Die Querschnittsvergrösserung 13 ist dabei derart, dass die Querschnittsfläche des Umlenkabschnittes 3 bezüglich des ersten bzw. des zweiten Rohrleitungsabschnittes 1, 2 vergrössert wird. Von der Figur 2 lässt sich diese Querschnittsvergrösserung durch die eingezeichneten Querschnitte Q1, Q2 und Q3 besonders gut erkennen.In a second variant, which is shown in the figures, the cross section of the deflection section 3 is enlarged in sections by an enlarged cross section 13. The cross-sectional enlargement 13 is such that the cross-sectional area of the deflection section 3 is enlarged with respect to the first and the second pipeline section 1, 2, respectively. Of the Figure 2 This cross-sectional enlargement can be seen particularly well by the cross-sections Q1, Q2 and Q3 shown.

Die Querschnittsvergrösserung 13 erstreckt sich im Querschnitt gesehen ausgehend vom geometrischen kreisförmigen Querschnitt 14 des Umlenkabschnittes 3 vorzugsweise ausschliesslich über einen Teilbereich des kreisförmigen Querschnitts 14 hinaus. Das Hinauserstrecken ist dabei derart, dass im Querschnitt gesehen ein Querschnittsbereich mit dem ursprünglichen kreisförmigen Querschnitt 14 und ein Querschnittsbereich mit der Querschnittsvergrösserung 13 geschaffen wird. Die Leitlinie L3 erstreckt sich dabei durch die geometrischen Zentren des ursprünglichen kreisförmigen Querschnitts 14.The cross-sectional enlargement 13, viewed in cross-section, starting from the geometrical circular cross-section 14 of the deflection section 3, preferably extends exclusively over a partial area of the circular cross-section 14. The extension is such that, seen in cross section, a cross-sectional area with the original circular cross-section 14 and a cross-sectional area with the cross-sectional enlargement 13 are created. The guideline L3 extends through the geometric centers of the original circular cross-section 14.

Vorzugsweise vergrössert die Querschnittsvergrösserung 14 den Radius des kreisförmigen Querschnitts um 5% bis 20% oder um 10% bis 20%.The cross-sectional enlargement 14 preferably increases the radius of the circular cross-section by 5% to 20% or by 10% to 20%.

Die Querschnittsvergrösserung erstreckt sich bei Blick in Richtung der ersten Leitlinie L1 auf die Seite, in welche der Teilabschnitt 4 des Umlenkabschnittes 3 ausgelenkt ist.When looking in the direction of the first guideline L1, the enlarged cross-section extends to the side into which the section 4 of the deflection section 3 is deflected.

Die Figur 9a zeigt einen Querschnitt, welcher auf der Referenzebene R9 liegt. Hier kann gut erkannt werden, dass die Leitlinie im Zentrum des ursprünglichen kreisförmigen Querschnittes 14 liegt und dass sich die Querschnittsvergrösserung seitlich nach aussen erstreckt.The Figure 9a shows a cross section which lies on the reference plane R9. It can be clearly seen here that the guideline lies in the center of the original circular cross-section 14 and that the enlarged cross-section extends laterally outward.
