Die in den Figuren 1 und 2 dargestellte Ausführung des Strömungsverteilers gemäß der Erfindung umfaßt ein Rohrteil 1 mit zylindrischer Wand mit kreisförmiger Außenkontur.The embodiment of the shown in Figures 1 and 2 Flow distributor according to the invention comprises a pipe part 1 with a cylindrical wall with a circular outer contour.

Das Rohrteil 1 umfaßt eine erste Öffnung 2 und eine zweite Öffnung 3. Im durchgehenden Teil der zylindrischen Wand des Rohrteils 1 erstreckt sich von der ersten Öffnung 2 ein Strömungsleiter 4 aus.The pipe part 1 comprises a first opening 2 and a second Opening 3. In the continuous part of the cylindrical wall of the Pipe part 1 extends from the first opening 2 Flow guide 4 out.

Nahe der ersten Öffnung 2 ist an dem Außenumfang der zylindrischen Wand ein Abstandhalterring 5 in einer senkrecht zur Achse des Rohrteiles 1 gelegenen Ebene angebracht. Im Bereich des Abstandhalterringes 5, der sich auf der der ersten Öffnung 2 abgewandten Seite des Strömungsverteilers 4 befindet, sind zwei Durchflußöffnungen 11a, 11b vorgesehen (s. Figur 2). Der Abstandhalterring 5 ist auf der Seite der ersten Öffnung 2 geschlossen und fluchtet mit der Umfangskante der ersten Öffnung 2. Auf diese Weise bildet der Abstandhalterring 5 eine Plattform 12, die sich an einen ersten Durchflußkanal 10 des Rohrteiles 1 anschließt.Near the first opening 2 is on the outer periphery cylindrical wall a spacer ring 5 in a vertical attached to the axis of the pipe part 1 level. in the Area of the spacer ring 5, which is on the first Opening 2 facing away from the flow distributor 4 is located, two flow openings 11a, 11b are provided (s. Figure 2). The spacer ring 5 is on the first side Opening 2 closed and aligned with the peripheral edge of the first opening 2. In this way, the spacer ring forms 5 a platform 12, which is connected to a first flow channel 10 of the pipe part 1 connects.

An der Plattform 12 sind weiter zwei Wände 8 angebracht, die sich von der Plattform aus in einer Richtung parallel zur Achse des Rohrteiles 1 erstrecken. Die Wände 8 sind in einer Ebene gelegen. Jede der Wände wird von jeweils einer Stütze 9 gestützt.On the platform 12 two walls 8 are further attached, the from the platform in a direction parallel to Extend the axis of the pipe part 1. The walls 8 are in one Level. Each of the walls is supported by a column 9 supported.

In der in den Figuren 1 und 2 dargestellten Ausführungsform besteht der Strömungsleiter aus einem Teil einer Zylinderwand, die sich über 180° entlang der Umfangskante der ersten Öffnung 2 erstreckt. Der Strömungsleiter erstreckt sich vom Abstandhalterring 5 parallel zur Achse des Rohrteils 1 in einer vom Rohrteil 1 abgewandten Richtung. Die Kante des Strömungsleiters 4 bildet zusammen mit der Umfangskante der ersten Öffnung 2 die Kontur einer Einströmöffnung 2a.In the embodiment shown in Figures 1 and 2 the flow guide consists of part of a cylinder wall, which extend over 180 ° along the peripheral edge of the first opening 2 extends. The flow guide extends from Spacer ring 5 parallel to the axis of the tubular part 1 in a direction facing away from the pipe part 1. The edge of the Flow guide 4 forms together with the peripheral edge of the first opening 2, the contour of an inflow opening 2a.

An dem Strömungsleiter sind in der in den Figuren 1 und 2 dargestellten Ausführung zwei Leitelemente in der Form von Flanschkanten 7, die sich in einer Ebene parallel zur Achse des Rohrteiles 1 erstrecken, angebracht. Der Strömungsleiter wird von einem Stützelement 13 gestützt.1 and 2 shown execution two guide elements in the form of Flange edges 7, which are in a plane parallel to the axis extend the pipe part 1, attached. The flow guide is supported by a support element 13.

Am Umfangsrand des Abstandhalterringes 5 sind mindestens drei bewegliche und federnde Vorsprünge 6 angebracht mit denen der Strömungsverteiler gemäß der Erfindung in einer Anschlußöffnung für ein Ausdehnungsgefäß verriegelt werden kann.At least three are on the peripheral edge of the spacer ring 5 movable and resilient projections 6 attached to those of Flow distributor according to the invention in one Connection opening for an expansion vessel can be locked can.

Die Figur 3 stellt ein Richtelement 30 dar, das an dem Strömungsverteiler gemäß der Erfindung angebracht werden kann. Das Richtelement umfaßt einen Teil einer Zylinderwand 14, deren Radius vorzugsweise mit dem Innenradius des Leitungsteiles in Höhe der Anschlußöffnung, in welcher der Strömungsverteiler angebracht werden muß, übereinstimmt. In einer Ebene senkrecht zur Zylinderwand 14 ist eine Trennwand 15, die fest mit dem Zylinderwand 14 verbunden ist, angebracht. An der Trennwand 15 sind Führungen 16 angebracht, die mit den Flanschrändern 7 zusammenwirken können, um das Richtelement an dem Strömungsverteiler zu befestigen. In der Trennwand 15 ist eine Öffnung 17 vorgesehen.FIG. 3 shows a straightening element 30 which is attached to the Flow distributor can be attached according to the invention. The straightening element comprises part of a cylinder wall 14, whose radius is preferably with the inner radius of the Line part at the level of the connection opening in which the Flow distributor must be attached, agrees. In A plane perpendicular to the cylinder wall 14 is a partition 15, which is firmly connected to the cylinder wall 14, appropriate. Guides 16 are attached to the partition 15, which can cooperate with the flange edges 7 to Attach the straightening element to the flow distributor. In the Partition 15, an opening 17 is provided.

In der Figur 4 ist ein Querschnitt des Richtelements entlang der Linie A-A in der Figur 3 dargestellt. In dieser Figur 4 ist zu sehen, daß die Zylinderwand 14 eine Sattelform hat. Dies ergibt sich durch die Tatsache, daß die projizierte Fläche der Zylinderwand 14 im wesentlichen kreisförmig sein muß, um letztendlich in eine Anschlußöffnung gesteckt werden zu können. Die Anschlußöffnung für ein Ausdehnungsgefäß wird oftmals in einem T-Stück angebracht sein.In Figure 4 is a cross section of the straightening element along the line A-A shown in Figure 3. In this figure 4 it can be seen that the cylinder wall 14 has a saddle shape. This arises from the fact that the projected Surface of the cylinder wall 14 may be substantially circular must ultimately be inserted into a connection opening to be able to. The connection opening for an expansion vessel is often be attached in a T-piece.

In der Figur 5 ist der Strömungsverteiler im in einem T-Stück montierten Zustand dargestellt. Das T-Stück 18 hat einen Hauptströmungskanal 19, durch den während des Betriebes eine Flüssigkeit strömen kann, insbesondere Wasser. In einer Richtung senkrecht zur Achse des Hauptströmungskanals 19 ist eine Seitenanschlußmuffe 20 angebracht. In einen durch die Anschlußmuffe 20 gebildeten Durchgang ist der Strömungsverteiler gemäß der Erfindung gesteckt. Der Abstandhalterring 5 gewährleistet die Zentrierung des Rohrteils 1 in der durch die Anschlußmuffe 20 gebildeten Öffnung. Die Vorsprünge 6 an dem Außenumfang des Abstandhalterringes 5 greifen in ein Innengewinde 21 der Anschlußmuffe 20. Damit wird errreicht, daß der Strömungsverteiler im T-Stück 18 fixiert ist.In Figure 5, the flow distributor is in a T-piece shown assembled state. The T-piece 18 has one Main flow channel 19 through which a during operation Liquid can flow, especially water. In a Direction perpendicular to the axis of the main flow channel 19 a side connection sleeve 20 attached. In one through the Connection sleeve 20 formed passage is the Flow distributor inserted according to the invention. The Spacer ring 5 ensures the centering of the Pipe part 1 in the formed by the connecting sleeve 20 Opening. The projections 6 on the outer circumference of the Spacer ring 5 engage in an internal thread 21 of the Connection sleeve 20. This ensures that the Flow distributor is fixed in the T-piece 18.

Das Richtelement ist im dargestellten Beispiel mit den Führungselementen 16 über die Flanschkanten 7 des Strömungsverteilers geschoben worden. Die Trennwand 15 sperrt dabei einen Teil der Einströmöffnung 2a ab. Die Abmessungen der Führungselemente 16 und die Flanschkanten 7 sind derart, daß das Richtelement 30 und der Strömungsleiter 4 durch Kraftschluß mit einander gekoppelt sind.The straightening element is in the example shown with the Guide elements 16 over the flange edges 7 of the Flow distributor has been pushed. The partition 15 locks part of the inflow opening 2a. The dimensions the guide elements 16 and the flange edges 7 are such that the directional element 30 and the flow guide 4 through Adhesion are coupled with each other.

Es ist auch möglich, den Strömungsleiter 4 konisch auszuführen, so daß das Richtelement 30 klemmend an dem Strömungsleiter 4 angebracht werden kann.It is also possible for the flow guide 4 to be conical execute, so that the straightening element 30 is clamped to the Flow guide 4 can be attached.

Während der Montage des Strömungsverteilers in ein T-Stück 18 wird der Strömungsverteiler so weit in die Anschlußmuffe gesteckt, daß der Abstandhalterring 5 sich vollständig in der Anschlußmuffe 20 befindet. Dadurch wird ein Teil des in der Anschlußmuffe 20 vorhandenen Durchgangs durch die Plattform 12 des Abstandhalterringes 5 gesperrt. Das Rohrteil 1 bildet in Zusammenarbeit mit der Anschlußmuffe 20 einen zweiten Durchflußkanal 22. Der zweite Durchflußkanal wird durch den Raum zwischen dem Rohrteil 1 und der Anschlußmuffe 20 gebildet. Im dargestellten Ausführungsbeispiel sind der erste Durchflußkanal 10 und der zweite Durchflußkanal 22 konzentrisch. Dies ist jedoch keine notwendige Bedingung. Es ist wohl wichtig, daß der erste Durchflußkanal 10 und der zweite Durchflußkanal 22 mit ähnliche Durchströmkanälen in einen Anschlußnippel eines durchströmbaren Ausdehnungsgefäß, das mittels des T-Stücks 18 mit dem Leitungssystem verbunden ist, fluchten können.During the assembly of the flow distributor in a T-piece 18 the flow distributor is so far into the connection sleeve inserted that the spacer ring 5 is completely in the Connection sleeve 20 is located. This will result in part of the Connection sleeve 20 existing passage through the platform 12 the spacer ring 5 locked. The pipe part 1 forms in Cooperation with the connecting sleeve 20 a second Flow channel 22. The second flow channel is through the Space between the pipe part 1 and the connecting sleeve 20th educated. In the illustrated embodiment, the first Flow channel 10 and the second flow channel 22nd concentric. However, this is not a necessary condition. It it is probably important that the first flow channel 10 and second flow channel 22 with similar flow channels in a connection nipple of a flow-through expansion vessel, that is connected to the pipe system by means of the T-piece 18 is, can escape.

Die Zylinderwand 14 des Richtelementes 30 gewährleistet, daß der Strömungsverteiler gemäß vorher bestimmter Ausrichtung in das T-Stück 18 gesteckt wird. Dabei ist eine Ebene durch die Flanschränder des Strömungsleiters 4 im wesentlichen senkrecht zur Achse des Hauptströmungskanals 19 gerichtet. Auf diese Weise bildet der Strömungsleiter 4 zusammen mit der Trennwand 15 einen Strömungswiderstand für das, zumindest während des Betriebes, durch den Hauptströmungskanal 19 strömende Medium. Die Wände 8 bilden während des Betriebes ebenfalls einen Strömungswiderstand für das durch den Hauptströmungskanal 19 strömende Wasser. Der gesamte Strömungswiderstand bewirkt, daß zumindest ein Teil des durch den Hauptströmungskanal strömenden Wassers über den ersten Durchflußkanal 10 zu dem mit dem T-Stück verbundenen Ausdehnungsgefäß strömt (nicht dargestellt). Letztendlich wird das Wasser über den zweiten Durchflußkanal 22 zu dem Hauptströmkanal 19 stromabwärts vom Strömungsleiter 4 zurückströmen. Selbstverständlich kann das Wasser auch in umgekehrter Richtung durch den zweiten Durchflußkanal 22 und den ersten Durchflußkanal 10 strömen.The cylinder wall 14 of the straightening element 30 ensures that the flow distributor according to predetermined orientation in the T-piece 18 is inserted. There is a level through Flange edges of the flow guide 4 substantially perpendicular directed to the axis of the main flow channel 19. To this The flow guide 4 forms together with the partition 15 a flow resistance for that, at least during the Operation, flowing through the main flow channel 19 medium. The walls 8 also form one during operation Flow resistance for that through the main flow channel 19 pouring water. The total flow resistance causes at least part of that through the main flow channel flowing water over the first flow channel 10 to the expansion tank connected to the T-piece flows (not ) Shown. Ultimately, the water over the second Flow channel 22 to the main flow channel 19 downstream of Flow back flow conductor 4. Of course it can Water also in reverse through the second Flow channel 22 and the first flow channel 10 flow.

Die in den Figuren 6-9 dargestellte zweite Ausführung des Strömungsverteilers gemäß der Erfindung umfaßt ein Basisteil 31 mit einer zylindrischen Buchse 32 mit einer vorzugsweise kreisförmigen Querschnittskontur. Das Basisteil 31 umfaßt weiter ein Rohrteil 33, das vorzugsweise konzentrisch in der zylindrischen Buchse 32 angebracht ist. Abstandhalter 34 gewährleisten die konzentrische Positionierung des Rohrteiles 33 in der zylindrischen Buchse 37. Der Innenraum des Rohrteils 33 bildet zumindest einen Teil eines ersten Durchflußkanals 35, und der Raum zwischen der zylindrischen Buchse 32 und dem Rohrteil 33 bildet einen zweiten Durchflußkanal 36.The second embodiment of the shown in Figures 6-9 Flow distributor according to the invention comprises a base part 31 with a cylindrical sleeve 32 with a preferably circular cross-sectional contour. The base part 31 comprises further a pipe part 33, which is preferably concentric in the cylindrical socket 32 is attached. Spacer 34 ensure the concentric positioning of the pipe part 33 in the cylindrical bush 37. The interior of the tubular part 33 forms at least part of a first flow channel 35, and the space between the cylindrical sleeve 32 and the Pipe part 33 forms a second flow channel 36.

Im Rohrteil 33 ist der vorzugsweise rohrförmige Strömungsleiter 37 (s. Figur 8) drehbar angebracht. Um zu verhindern, daß der Strömungsleiter 37 aus dem Rohrteil heraus schieben kann, ist an dem Außenumfang des Strömungsleiters 37, nahe dessen in das Rohrteil 33 geschobenen Endes, eine umlaufende Kante 38 angebracht. In der Innenwand des Rohrteiles 33 ist eine dazugehörige Nut 39 (s. Figur 9) angebracht, die mit der Kante 38 zusammen wirkt, um den Strömungsleiter 37 in dem Rohrteil 33 zu fixieren. Die Kante 38 und die Nut haben Abmessungen, die eine Rotatiionsbewegung des Strömungsleiters 37 ermöglichen. Selbstverständlich kann die Kante 38 auch an der Innenwand des Rohrteiles 33 und die dazugehörige Nut 39 an dem Außenumfang des Strömungsleiters angebracht sein.The tubular part 33 is preferably tubular Flow guide 37 (see Figure 8) rotatably attached. In order to prevent the flow guide 37 from coming out of the tubular member can slide is on the outer circumference of the flow guide 37, near the end pushed into the tubular part 33, a peripheral edge 38 attached.

Um eine elastische Verformung des Strömungsleiters 37 zu ermöglichen, wenn dieser in das Rohrteil 33 eingebracht wird, kann der Strömungsleiter 37 an dem in das Rohrteil 33 geschobenen Ende eine Einschneidung in Längsrichtung des Strömungsleiters 37 und über eine vorher bestimmte Länge haben.To elastic deformation of the flow guide 37 enable, if this is introduced into the tube part 33, can the flow conductor 37 on the in the pipe part 33rd pushed end an incision in the longitudinal direction of the Flow guide 37 and over a predetermined length to have.

Der Strömungsleiter 37 ist im Bereich des freien Endes am Umfang mit einer Einströmöffnung 40 versehen. Die Einströmöffnung 40 erlaubt eine Strömung ins Innere des Strömungsleiters 37, wobei die Strömungsrichtung beim Einströmen in einem Winkel zur Achse des Strömungsleiters 37 steht. Das freie Ende des Strömungsleiters 37 ist derart geformt, daß zumindest während des Betriebs Wasser durch die Einströmöffnung 40 hereinströmen kann.The flow guide 37 is in the region of the free end Provided circumference with an inflow opening 40. The Inflow opening 40 allows a flow into the interior of the Flow conductor 37, the direction of flow at Inflow at an angle to the axis of the flow guide 37 stands. The free end of the flow guide 37 is such shaped that at least during operation water through the Inflow opening 40 can flow in.

Um letztendlich eine richtige Position des Strömungsleiters zu gewährleisten, wobei die Einströmöffnung 40 stromaufwärts gerichtet ist, ist an der Außenfläche des Strömungsleiters 37, nahe dem freien Ende, eine ebene Richtfahne 41 angebracht. Wenn das Wasser an der Richtfahne vorbei strömt, übt das Wasser eine Kraft, die in Strömungsrichtung gerichtet ist, auf die Richtfahne aus. Wenn die Fläche der Richtfahne 41 unter einem Winkel mit einer Strömungsrichtung des strömenden Wassers steht, erzeugt die durch das Wasser auf die Richtfahne 41 ausgeübte Kraft ein Moment, so daß der Strömungsleiter 37 rotieren wird, bis die Fläche der Richtfahne 41 der Strömungsrichtung entspricht.Ultimately, a correct position of the flow guide ensure, the inflow opening 40 upstream is directed on the outer surface of the flow guide 37, near the free end, a flat flag 41 attached. If the water flows past the directional flag, that is good practice Water a force that is directed in the direction of flow the flag. If the surface of the flag 41 under an angle with a flow direction of the flowing Water is standing, generated by the water on the flag 41 applied force a moment, so that the flow guide 37th will rotate until the surface of the directional flag 41 Direction of flow corresponds.

Anstatt einer ebenen Richtfahne kann auch ein V-förmiges Richtorgan angebracht sein, dessen Symmetrieebene und die Achse des Strömungsleiters in einer Ebene liegen.Instead of a flat directional flag, a V-shaped one can also be used Directional organ attached, its plane of symmetry and the Axis of the flow guide lie in one plane.
