Description

Die Erfindung betrifft einen Rohrverteiler mit hydraulischem Entkoppler gemäß Oberbegriff des Anspruchs 1.The invention relates to a pipe distributor with a hydraulic decoupler according to the preamble of claim 1.

In Heizungsanlagen werden zur hydraulischen Entkopplung des primärseitigen Flüssigkeitskreislaufs und des sekundärseitigen Flüssigkeitskreislaufs hydraulische Entkoppler eingesetzt, die auch als Wärmestromtauscher oder hydraulische Weiche bezeichnet werden. Bekannte hydraulische Entkoppler bestehen aus einem Gehäuse, welches einen Entkopplungsraum umschließt, an dem an gegenüberliegenden Seiten die Anschlüsse für den Primärkreis und den Sekundärkreis vorgesehen sind. Dabei sind die beiden Vorlaufanschlüsse fluchtend angeordnet und ebenso auch die beiden Rücklaufanschlüsse.In heating systems, hydraulic decouplers are used for the hydraulic decoupling of the primary-side liquid circuit and the secondary-side liquid circuit, which are also referred to as heat flow exchangers or hydraulic switches. Known hydraulic decouplers consist of a housing which encloses a decoupling space on which the connections for the primary circuit and the secondary circuit are provided on opposite sides. The two flow connections are aligned, as are the two return connections.

Aus dem deutschen Gebrauchsmuster 88 06 448 ist ein Rohrverteiler mit einem auf am Rohrverteiler abstehende Anschlußstutzen aufgesetzten hydraulischen Entkoppler bekannt, der die oben genannten Merkmale gegenüberliegend fluchtender Anschlüsse besitzt. Der dort verwendete hydraulische Entkoppler hat ein eigenes Gehäuse und entspricht somit dem oftmals im Abstand von den Rohrverteilern angeordneten herkömmlichen hydraulischen Entkopplern, die als selbständige Einheit ausgebildet sind und mit einem entsprechenden Kostenaufwand hergestellt werden müssen und bei der Montage außer einem beträchtlichen Platzbedarf auch noch einen beträchtlichen Montageaufwand erfordern.From the German utility model 88 06 448 a pipe distributor is known with a hydraulic decoupler placed on the connecting piece projecting from the pipe distributor, which has the above-mentioned characteristics of opposing aligned connections. The hydraulic decoupler used there has its own housing and thus corresponds to the conventional hydraulic decouplers, which are often arranged at a distance from the pipe manifolds and are designed as an independent unit and must be produced at a corresponding cost and, in addition to a considerable space requirement, also require a considerable assembly effort during assembly.

Der Erfindung liegt die Aufgabe zugrunde, einen Rohrverteiler mit hydraulischem Entkoppler für Heizungsanlagen, Kühlanlagen oder dergleichen zu schaffen, der möglichst wenig Platz in Anspruch nimmt und einen möglichst geringen Montageaufwand erfordert.The invention has for its object to provide a pipe distributor with hydraulic decoupler for heating systems, cooling systems or the like, which takes up as little space as possible and requires as little assembly effort.

Die Lösung dieser Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale erhalten. Der hydraulische Entkoppler wird in Form eines Entkopplungsraums im Rohrverteiler integriert, wodurch Verbindungsleitungen und Anschlußstutzen zu der Vorlaufkammer und der Rücklaufkammer des Rohrverteilers entfallen können. Der hydraulische Entkoppler ist sehr einfach und platzsparend realisierbar. Durch die Integration im Rohrverteiler wird auch eine thermische Isolierung des Entkopplers äußerst einfach, da hierfür die herkömmlichen Isolierschalen, wie diese zur Isolation von Rohrverteilern bekannt sind, verwendet werden können. Verbindungsleitungen, die sich zwischen Entkoppler und Rohrverteiler erstrecken, entfallen bei der erfindungsgemäßen Ausführung, so daß auch hierfür sonst notwendige Rohrisolierungen nicht mehr erforderlich sind.This object is achieved by the features specified in claim 1. The hydraulic decoupler is integrated in the form of a decoupling space in the pipe distributor, whereby connecting lines and connecting pieces to the flow chamber and the return chamber of the pipe distributor can be omitted. The hydraulic decoupler is very simple and space-saving. The integration in the pipe distributor also makes thermal insulation of the decoupler extremely simple, since the conventional insulating shells, as are known for the insulation of pipe distributors, can be used for this. Connecting lines which extend between the decoupler and the pipe distributor are omitted in the embodiment according to the invention, so that pipe insulation which is otherwise necessary for this is also no longer required.

Bei der bevorzugten Ausführungsform besteht der Rohrverteiler aus einem langgestreckten Gehäuse, welches durch eine im innern verlaufende Trennwand in eine Vorlaufkammer und eine Rücklaufkammer unterteilt ist. Zur Bildung des Entkopplungsraums genügt es, eine Aussparung in der Trennwand vorzusehen, wobei hierfür eine rechteckige, runde oder anders geformte Aussparung vorgesehen sein kann. Die Aussparung kann auch dadurch gebildet werden, daß die Trennwand im Abstand von einer der Gehäusestirnwände endet. An dieser Stelle sei erwähnt, daß die Trennwand eine ebene oder wellige oder anders geformte Form haben kann. Die Ausbildung des hydraulischen Entkopplers durch eine Aussparung in der Trennwand stellt eine äußerst einfache Realisierungsmöglichkeit dar.In the preferred embodiment, the pipe distributor consists of an elongated housing, which is divided into a flow chamber and a return chamber by an internal partition. To form the decoupling space, it is sufficient to provide a cutout in the partition, a rectangular, round or other shaped cutout being provided for this purpose. The recess can also be formed in that the partition ends at a distance from one of the housing end walls. At this point it should be mentioned that the partition can have a flat or wavy or other shape. The Forming the hydraulic decoupler through a recess in the partition wall is an extremely simple implementation option.

Die Rücklaufkammer und die Vorlaufkammer des Rohrverteilers könnnen jedoch auch in Form von parallel verlaufenden Rohren ausgebildet sein, die in einen an deren Stirnseite ausgebildeten gemeinsamen Entkopplungsraum münden.The return chamber and the flow chamber of the pipe distributor can, however, also be designed in the form of parallel pipes which open into a common decoupling space formed on the end face thereof.

Um eine bessere Verwirbelung oder Vermischung des Rücklaufstroms mit dem Vorlaufstrom im Übergangsbereich zwischen Entkopplungsraum und Vorlaufkammer zu erreichen, können an dieser Stelle geeignete Verwirbelungselemente, wie Prall- oder Leitbleche, vorgesehen sein. Im Anschluß an die Verwirbelungselemente erhält man eine homogene Strömung, die eine genauere Temperaturbestimmung des in die Vorlaufkammer fließenden Mediums ermöglicht.In order to achieve a better swirling or mixing of the return flow with the flow in the transition area between the decoupling space and the flow chamber, suitable swirling elements, such as baffles or baffles, can be provided at this point. Following the swirling elements, a homogeneous flow is obtained which enables a more precise determination of the temperature of the medium flowing into the flow chamber.

Eine Weiterbildung der Erfindung sieht vor, daß der Vorlaufanschluß des Primärkreises einen nach innen in den Entkopplungsraum ragenden Rohrabschnitt hat. Auch diese Maßnahme dient zur besseren Vermischung des Rückstroms aus der Rücklaufkammer mit dem Vorlaufstrom, der in den Entkopplungsraum eingespeist wird.A further development of the invention provides that the flow connection of the primary circuit has a pipe section projecting inwards into the decoupling space. This measure also serves to improve the mixing of the return flow from the return chamber with the flow stream which is fed into the decoupling chamber.

Der Rücklaufanschluß des Primärkreises kann in einem an den Entkopplungsraum angrenzenden Abschnitt der Rücklaufkammer angeordnet sein, wodurch eine teilweise Erstreckung des Entkopplungsraums in die Rücklaufkammer entsteht. Der Abstand zwischen Vorlaufanschluß und Rücklaufanschluß des Primärkreises wird dadurch erhöht, was bei kleinen Rohrverteilerbaugrößen zweckmäßig sein kann.The return connection of the primary circuit can be arranged in a section of the return chamber which adjoins the decoupling space, as a result of which the decoupling space is partially extended into the return chamber. The distance between the flow connection and the return connection of the primary circuit is increased, which can be expedient in the case of small pipe distributor sizes.

Um eine einheitliche Ausrichtung der Anschlußstutzen am Rohrverteilergehäuse zu erhalten, können der Vorlaufanschluß und der Rücklaufanschluß des Primärkreises fluchtend mit Rohrverteileranschlüssen nebeneinander an einer Seite des Rohrverteilergehäuses abstehen. Auf diese Weise erhält man eine übersichtliche Leitungsführung, wobei einer der Anschlüsse des hydraulischen Entkopplers durch eine der beiden Kammern des Rohrverteilers hindurch geführt ist.In order to obtain a uniform alignment of the connecting pieces on the pipe distributor housing, the flow connection and the return connection of the primary circuit can project in alignment with pipe distributor connections next to one another on one side of the pipe distributor housing. To this In this way, a clear cable routing is obtained, one of the connections of the hydraulic decoupler being passed through one of the two chambers of the pipe distributor.

Der Rohrverteiler, bei dem der hydraulische Entkoppler in Form eines im Verteilergehäuses ausgebildeten Entkopplungsraums integriert ist, besitzt gegen herkömmlichen hydraulischen Entkopplern große Vorteile, die insbesondere im einfachen Aufbau, im geringen Platzbedarf und in der äußerst einfachen Montage zu sehen sind. Weitere Vorteile, wie Vereinfachung der thermischen Isolierung und vielfältige Möglichkeiten der Anbringung der Entkoppler-Anschlüsse, sind hier ebenfalls zu nennen.The pipe distributor, in which the hydraulic decoupler is integrated in the form of a decoupling space formed in the distributor housing, has great advantages over conventional hydraulic decouplers, which can be seen in particular in the simple construction, the small space requirement and the extremely simple assembly. Other advantages, such as simplification of the thermal insulation and various options for attaching the decoupler connections, can also be mentioned here.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing.

  • Figur 2 den Schnitt AA von Figur 1,
  • Figur 3 ein Ausführungsbeispiel eines Rohrverteilers mit Entkoppler, bei dem der Vorlaufanschluß des Primärkreises in den Entkopplungsraum ragt,

Show it:
  • 1 shows the arrangement of the pipe distributor with hydraulic decoupler in a heating system with two boilers,
  • FIG. 2 shows the section AA from FIG. 1,
  • 3 shows an exemplary embodiment of a pipe distributor with decoupler, in which the flow connection of the primary circuit projects into the decoupling space,
  • Figure 4 shows another embodiment with a swirling element in the transition region between the decoupling space and the flow chamber of the pipe distributor and
  • Figure 5 shows an embodiment in which the flow chamber and the return chamber of the pipe distributor are designed as pipes.

Der in Figur 1 dargestellte Rohrverteiler 1 mit integriertem hydraulischen Entkoppler 2 ist Teil einer Heizungsanlage, die primärseitig zwei Heizkessel 3, 4 und sekundärseitig zwei Heizkreise 5, 6 umfaßt. Der Rohrverteiler 1 ist über Anschlußstutzen 7 bis 12 an Vorlaufleitungen VL und Rücklaufleitungen RL des Primär- und Sekundärkreises angeschlossen.The pipe distributor 1 shown in FIG. 1 with an integrated hydraulic decoupler 2 is part of a heating system which comprises two heating boilers 3, 4 on the primary side and two heating circuits 5, 6 on the secondary side. The pipe distributor 1 is connected via connecting pieces 7 to 12 to supply lines VL and return lines RL of the primary and secondary circuits.

Der Rohrverteiler 1 besitzt ein langgestrecktes Gehäuse mit quadratischem oder rechteckigem Querschnitt, welches außer im Bereich des hydraulischen Entkopplers 2 durch eine waagerechte Trennwand 13 in eine Vorlaufkammer 14 und eine Rücklaufkammer 15 im Innern unterteilt ist. Die Trennwand 13 endet im Abstand vor der linken stirnseitigen Gehäusewand 16, so daß eine Aussparung 17 entsteht, die einen Übergang von der Rücklaufkammer 15 zur Vorlaufkammer 14 bildet. In diesem Übergangsbereich, der von der Gehäusewand 16 und den angrenzenden Stirnwänden 18 des Rohrverteilers 1 gebildet wird, befindet sich der Entkopplungsraum 19 des hydraulischen Entkopplers 2. Dieser Entkopplungsraum 19 ist zur Vorlaufkammer 14 und zur Rücklaufkammer 15 vollständig offen, so daß die RücklaufStrömung 20 im erforderlichen Maße durch die Aussparung 17 in die Vorlaufkammer 14 strömen kann. Dabei erfolgt eine Vermischung mit der über den Vorlaufanschluß 21 in den Entkopplungsraum 19 einströmenden Vorlaufströmung 22 des Primärkreises. Die über den Rücklaufanschluß 23 in den Primärkreis zurückgeführte Rücklaufströmung 24 nimmt einen entsprechenden Anteil der Rücklaufströmung 20 auf, wie Strömungsanteile der Vorlaufströmung 22 in die Vorlaufkammer 14 gelangen.The pipe distributor 1 has an elongated housing with a square or rectangular cross section, which, apart from in the region of the hydraulic decoupler 2, is divided into a flow chamber 14 and a return chamber 15 inside by a horizontal partition wall 13. The partition 13 ends at a distance from the left front housing wall 16, so that a recess 17 is formed which forms a transition from the return chamber 15 to the flow chamber 14. In this transition area, which is formed by the housing wall 16 and the adjacent end walls 18 of the pipe distributor 1, there is the decoupling space 19 of the hydraulic decoupler 2. This decoupling space 19 is completely open to the flow chamber 14 and the return chamber 15, so that the return flow 20 in required dimensions can flow through the recess 17 into the flow chamber 14. This mixes with the flow 22 of the primary circuit flowing into the decoupling space 19 via the flow connection 21. The return flow 24, which is returned to the primary circuit via the return connection 23, takes up a corresponding proportion of the return flow 20, as flow components of the flow flow 22 reach the flow chamber 14.

Durch die Verwendung eines hydraulischen Entkopplers 2 zwischen der Vorlaufkammer 14 und der Rücklaufkammer 15 des Sekundärkreises wird eine hydraulische Entkopplung zwischen Primärkreis und Sekundärkreis erreicht. Der hydraulische Entkoppler 2 wirkt dabei gleichzeitig als Wärmestromtauscher zwischen dem Wärmestrom des Primärkreises und dem Wärmestrom des Sekundärkreises. Die Umlauf-Wassermenge in den Wärmeerzeugern des Primärkreises ist unabhängig von der Umlauf-Wassermenge im Sekundärkreis, wo sich die Wärmeabnehmer befinden. Nicht im Betrieb befindliche Wärmeerzeuger, beispielsweise Heizkessel, Thermen oder dergleichen, können hydraulisch abgesperrt werden, um den Primärkreis nicht mit einer unnötig großen Wassermenge betreiben zu müssen. Für jede Engeriequelle kann die Rücklauftemperatur angepaßt werden, um optimale Betriebsverhältnisse zu schaffen.By using a hydraulic decoupler 2 between the flow chamber 14 and the return chamber 15 of the secondary circuit, hydraulic decoupling between the primary circuit and the secondary circuit is achieved. The hydraulic decoupler 2 acts simultaneously as a heat flow exchanger between the heat flow Primary circuit and the heat flow of the secondary circuit. The amount of circulating water in the heat generators of the primary circuit is independent of the amount of circulating water in the secondary circuit, where the heat consumers are located. Heat generators that are not in operation, for example boilers, thermal baths or the like, can be shut off hydraulically in order not to have to operate the primary circuit with an unnecessarily large amount of water. The return temperature can be adjusted for each energy source in order to create optimal operating conditions.

In Figur 2 ist der Schnitt AA dargestellt, der insbesondere die Aussparung 17 zeigt, über und unter der sich der Entkopplungsraum 19 des hydraulischen Entkopplers 2 befindet.FIG. 2 shows section AA, which in particular shows the recess 17 above and below which the decoupling space 19 of the hydraulic decoupler 2 is located.

Figur 3 zeigt einen Rohrverteiler 1, bei dem der Vorlaufanschluß 21 einen in den Entkopplungsraum 19 ragenden Rohrabschnitt 25 hat. Außerdem ist der Rücklaufanschluß 23 des hydraulischen Entkopplers 2 durch die Vorlaufkammer 14 zu einer Öffnung 26 in der Trennwand 13 geführt, wie dies auch bei den für die Rücklaufleitungen RL des Sekundärkreises vorgesehenen Anschlußstutzen 10, 12 (Figur 1) vorgesehen ist.FIG. 3 shows a pipe distributor 1 in which the flow connection 21 has a pipe section 25 projecting into the decoupling space 19. In addition, the return connection 23 of the hydraulic decoupler 2 is guided through the flow chamber 14 to an opening 26 in the partition 13, as is also provided for the connecting pieces 10, 12 (FIG. 1) provided for the return lines RL of the secondary circuit.

Durch die spezielle Anordnung des Anschlußstutzen 8, der für die Rücklaufleitung des Primärkreises vorgesehen ist, erstreckt sich der Entkopplungsraum 19 bis in den Bereich unter die Öffnung 26 und somit geringfügig in den Bereich der Rücklaufkammer 15
In Figur 4 ist an dem Ende 27 der Trennwand 13, welches die Aussparrung 17 begrenzt, ein nach oben stehendes Verwirbelungselement 28 angeordnet, welches als Prallblech oder dergleichen ausgebildet sein kann. In Figur 4 und Figur 5 sind die Anschlüsse an die Rohrverteiler nur noch schematisch dargestellt.Due to the special arrangement of the connecting piece 8, which is provided for the return line of the primary circuit, the decoupling space 19 extends into the area under the opening 26 and thus slightly into the area of the return chamber 15
In FIG. 4, an upward swirling element 28, which can be designed as a baffle plate or the like, is arranged at the end 27 of the partition 13, which delimits the recess 17. In Figure 4 and Figure 5, the connections to the pipe manifold are shown only schematically.

Der Rohrverteiler 1 von Figur 5 besteht aus einem oberen Rohr 29, welches die Vorlaufkammer 14 bildet, und einem unteren Rohr 30, welches die Rücklaufkammer 15 bildet, wobei beide Rohre 29, 30 in einen linksseitig ausgebildeten Entkopplungsraum 19 des integrierten hydraulischen Entkopplers 2 münden.The pipe distributor 1 of FIG. 5 consists of an upper pipe 29, which forms the flow chamber 14, and a lower pipe 30, which forms the return chamber 15, both pipes 29, 30 opening into a decoupling space 19 of the integrated hydraulic decoupler 2 on the left side.

Es wird angemerkt, daß der Rohrverteiler mit hydraulischem Entkoppler nicht nur in Heizungsanlagen zwischen Primär- und Sekundärkreis einsetzbar ist, sondern gleichermaßen auch in Kühlanlagen und sonstigen Anlagen zur Entkopplung der primärseitigen und sekundärseitigen Flüssigkeitskreise einsetzbar ist.It is noted that the pipe distributor with hydraulic decoupler can be used not only in heating systems between the primary and secondary circuits, but also in cooling systems and other systems for decoupling the primary-side and secondary-side liquid circuits.
