Description

Die Erfindung betrifft einen Rohrverteiler für Heizungsanlagen, dessen Innenraum vorzugsweise durch eine Trennwand in eine Vor- und eine Rücklaufkammer unterteilt ist und der Anschlußstutzen für den Anschluß von Vor- und Rücklaufleitungen hat.The invention relates to a pipe distributor for heating systems, the interior of which is preferably divided into a supply and a return chamber by a partition and has the connecting piece for the connection of supply and return lines.

In Heizungsanlagen werden Rohrverteiler zur Verteilung des Wärmeträgers auf verschiedene Heizkreise eingesetzt. Ein derartiger Rohrverteiler ist aus der DE-OS 3 006 784 bekannt. Dieser bekannte Rohrverteiler hat mehrere nebeneinander angeordnete Anschlußstutzen, die abwechselnd zur Vorlaufkammer und zur Rücklaufkammer führen. Jeweils zwei benachbarte Anschlußstutzen, von denen der eine zur Vorlaufkammer und der andere zur Rücklaufkammer führt, bilden eine Heizgruppe. Die erforderliche Anzahl der Heizgruppen ergibt sich aus der Anzahl der Heizkreise, die an dem Rohrverteiler angeschlossen werden sollen. Rohrverteiler mit acht und mehr Anschlußgruppen sind durchaus gebräuchlich und weisen eine entsprechend große Länge auf.In heating systems, pipe distributors are used to distribute the heat transfer medium to different heating circuits. Such a pipe distributor is known from DE-OS 3 006 784. This known pipe distributor has several connecting pieces arranged side by side, which lead alternately to the flow chamber and the return chamber. Two adjacent connecting pieces, one of which leads to the flow chamber and the other to the return chamber, form a heating group. The required number of heating groups results from the number of heating circuits that are to be connected to the pipe distributor. Pipe distributors with eight or more connection groups are quite common and have a correspondingly large length.

Der Erfindung liegt die Aufgabe zugrunde, einen Rohrverteiler zu schaffen, der bei gleicher Anzahl von Heizgruppen eine geringere Längenausdehnung hat.The invention has for its object to provide a pipe distributor which has a smaller length expansion with the same number of heating groups.

Die Lösung dieser Aufgabe wird bei einem Rohrverteiler der eingangs genannten Gattung dadurch erhalten, daß jeweils zwei Anschlußstutzen, von denen der eine zur Vor- und der andere zur Rücklaufkammer führt, einen Doppelanschlußstutzen mit einem inneren und einem äußeren Anschlußstutzen bilden. Der äußere Anschlußstutzen kann dabei beispielsweise zur Vorlaufkammer und der innere Anschlußstutzen zur Rücklaufkammer führen. Dieser Rohrverteiler hat den Vorteil, daß sämtliche Anschlußstutzen an einer Seite des Rohrverteilers und in einer Linie herausgeführt werden können, wobei dieser Rohrverteiler bei gleicher Anzahl von Heizgruppen nur etwa halb so lang ist wie bekannte Rohrverteiler. Durch die geringere Länge des erfindungsgemäßen Rohrverteilers ergibt sich eine große Kostenersparnis. Es wird weniger Material für den Rohrverteiler und für Einbauschränke, in die dieser eingesetzt werden soll, benötigt. Die anzuschließenden Rohrleitungen können direkt oder über geeignete Doppelventile mit den Anschlußstutzen verbunden werden.The solution to this problem is obtained in a pipe distributor of the type mentioned in that two connecting pieces, one of which leads to the forward and the other to the return chamber, form a double connecting piece with an inner and an outer connecting piece. The outer connection piece can lead, for example, to the flow chamber and the inner connection piece to the return chamber. This pipe distributor has the advantage that all connection pieces can be led out on one side of the pipe distributor and in a line, this pipe distributor being only about half as long as known pipe distributors with the same number of heating groups. The shorter length of the pipe distributor according to the invention results in great cost savings. Less material is required for the pipe distributor and for built-in cabinets in which it is to be used. The pipelines to be connected can be connected to the connecting piece directly or via suitable double valves.

Einen besonders einfachen Aufbau für den Rohrverteiler erhält man dadurch, daß das Gehäuse des Rohrverteilers innen durch eine waagerechte Trennwand in Vor- und Rücklaufkammer unterteilt ist; daß die inneren Anschlußstutzen senkrecht in Öffnungen in der Trennwand eingesetzt und durch größere Gehäuseöffnungen, in die die äußeren Anschlußstutzen eingesetzt sind, aus dem Gehäuse herausgeführt sind. Die Trennwand sollte dabei möglichst so angeordnet sein, daß die inneren Anschlußstutzen eine hinreichend große Länge haben, damit sie an ihren herausgeführten Enden in gewissen Grenzen beweglich sind. Diese Beweglichkeit erleichtert nämlich den Anschluß von Armaturen oder Doppelrohrleitungen erheblich, da geringe Fertigungstoleranzen durch einfaches Verschieben der herausgeführten Enden ausgeglichen werden können.A particularly simple construction for the pipe distributor is obtained by dividing the housing of the pipe distributor on the inside by a horizontal partition into the flow and return chambers; that the inner connecting pieces are inserted vertically into openings in the partition and are led out of the housing through larger housing openings into which the outer connecting pieces are inserted. The partition should be arranged so that the inner connecting pieces have a sufficient length so that they can be moved within certain limits at their ends. This mobility namely makes the connection of fittings or double pipelines considerably easier, since small manufacturing tolerances can be compensated for by simply moving the ends that are brought out.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß der innere Anschlußstutzen weiter aus dem Gehäuse herausgeführt ist, als der äußere Anschlußstutzen. Das herausgeführte Ende des inneren Anschlußstutzens ist vorzugsweise wenigstens mit einem umlaufenden Dichtungsring versehen und kann konisch geformt sein. Auf den inneren Anschlußstutzen kann dann eine anzuschließende Armatur oder ein Innenrohr selbstdichtend aufgesteckt werden.A preferred embodiment of the invention provides that the inner connection piece is led further out of the housing than the outer connection piece. The lead-out end of the inner connecting piece is preferably provided with at least one circumferential sealing ring and can be conical in shape. A fitting to be connected or an inner tube can then be attached in a self-sealing manner to the inner connecting piece.

Zu Befestigungszwecken kann vorgesehen sein, daß wenigstens einer der beiden Anschlußstutzen eines Doppelanschlußstutzens am aus dem Gehäuse herausgeführten Ende ein Gewinde oder einen Flansch aufweist.For fastening purposes it can be provided that at least one of the two connecting pieces of a double connecting piece has a thread or a flange at the end led out of the housing.

Die inneren Anschlußstutzen sind insbesondere so ausgebildet, daß sie nur mit ihrem verteilerseitigen Ende mit dem Rohrverteiler verbunden und wenigstens doppelt so lang sind wie ihr Durchmesser. Auf diese Weise erhält man eine gewisse Beweglichkeit für diese Anschlußstutzen, wodurch die Montage von anzuschließenden Einrichtungen erheblich erleichtert wird. Besonders vorteilhaft ist es, den inneren Anschlußstutzen als dünnwandiges Messingrohr auszubilden, dagegen kann der übrige Rohrverteiler aus Stahlblech gefertigt sein. In diesem Zusammenhang wird darauf hingewiesen, daß der Druck des Heizmediums innerhalb und außerhalb des inneren Anschlußstutzens im wesentlichen gleich groß ist, weshalb dieser Anschlußstutzen ohne weiteres dünnwandiger ausgeführt sein kann, als der äußere Anschlußstutzen.The inner connecting pieces are in particular designed such that they are connected to the pipe distributor only at their distributor end and are at least twice as long as their diameter. In this way, a certain degree of mobility is obtained for these connecting pieces, which considerably simplifies the assembly of devices to be connected. It is particularly advantageous to design the inner connecting piece as a thin-walled brass tube, whereas the rest of the tube distributor can be made from sheet steel. In this connection, it is pointed out that the pressure of the heating medium inside and outside the inner connection piece is essentially the same, which is why this connection piece can be made more thin-walled than the outer connection piece.

Die Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigt

  • Fig. 1 einen erfindungsgemäßen Rohrverteiler,
  • Fig. 2 einen Teil des Rohrverteilers, der auf dem äußeren Anschlußstutzen eine Überwurfmutter hat,
  • Fig.3 einen Teil eines erfindungsgemäßen Rohrverteilers mit asymmetrischem innerem Anschlußstutzen und
  • Fig. 4 eine Abdeckplatte für die Anschlußstutzen.
The invention is explained in more detail below with reference to the drawings. It shows
  • 1 shows a pipe distributor according to the invention,
  • 2 shows a part of the pipe distributor which has a union nut on the outer connecting piece,
  • 3 shows a part of a pipe distributor according to the invention with an asymmetrical inner connecting piece and
  • Fig. 4 is a cover plate for the connecting piece.

Der in Fig. 1 dargestellte erfindungsgemäße Rohrverteiler ist teilweise im Schnitt gezeichnet. Das Gehäuse 1 des Rohrverteilers wird im Innern durch eine Trennwand 2 in eine Vorlaufkammer 3 und eine Rückiaufkammer4 unterteilt.The pipe distributor according to the invention shown in Fig. 1 is partially drawn in section. The housing 1 of the pipe distributor is divided on the inside by a partition 2 into a flow chamber 3 and a return chamber 4.

In der Trennwand 2 befinden sich Öffnungen 5, in die innere Anschlußstutzen 6 eingesetzt sind. Diese inneren Anschlußstutzen 6 sind durch zugeordnete, im Gehäuse 1 angebrachte Gehäuseöffnungen 7 hindurchgeführt. In die Gehäuseöffnungen 7 sind äußere Anschlußstutzen 8 ein gesetzt.In the partition 2 there are openings 5, in which inner connecting pieces 6 are inserted. These inner connecting pieces 6 are passed through associated housing openings 7 provided in the housing 1. In the housing openings 7 outer connecting pieces 8 are set.

Die äußeren Anschlußstutzen 8 können jeweils mit einem Außengewindeabschnitt 9 oder mit einem Flansch 15 versehen sein. Mittels einer Schraube 10 lassen sich Rohre oder Absperrorgane 11 am Rohrverteiler anschrauben. Die Rohre können aus einem Außen- und einem Innenrohr bestehen, die mittels einer Schraube 10 gleichzeitig am Rohrverteiler befestigt werden. Die Anschlußstutzen 6, 8 können aber auch mit anzuschließenden Rohren verlötet oder verschweißt werden.The outer connecting piece 8 can each be provided with an external thread section 9 or with a flange 15. Pipes or shut-off elements 11 can be screwed onto the pipe distributor by means of a screw 10. The tubes can consist of an outer tube and an inner tube, which are simultaneously fastened to the tube distributor by means of a screw 10. The connecting pieces 6, 8 can also be soldered or welded to pipes to be connected.

Für den Anschluß der Vorlauf- und Rücklaufleitungen können zwischen diesen und den zugehörigen Doppelanschlußstutzen als Doppelventile ausgebildete Absperrorgane angeordnet werden, mit denen die angeschlossenen Leitungen gleichzeitig geschlossen bzw. geöffnet werden können.For the connection of the supply and return lines, shut-off devices designed as double valves can be arranged between these and the associated double connecting piece, with which the connected lines can be closed or opened at the same time.

Einer der beiden inneren Anschlußstutzen 6 hat an seinem aus dem Gehäuse 1 herausgeführten Ende 12 einen Flansch 13, der eine vergrößerte Auflagefläche für einen Dichtring bietet. Die herausgeführten Enden 14 der äußeren Anschlußstutzen 8 können ebenfalls einen Flansch 15 haben, der eine Überwurfmutter 16 auf dem Anschlußstutzen 8 hält. Fig. 2 zeigt eine derartige Anordnung mit einer Überwurfmutter 16.One of the two inner connecting pieces 6 has at its end 12 led out of the housing 1 a flange 13, which offers an enlarged contact surface for a sealing ring. The led out ends 14 of the outer connecting piece 8 may also have a flange 15 which holds a union nut 16 on the connecting piece 8. 2 shows such an arrangement with a union nut 16.

Die inneren Anschlußstutzen 6 werden vorzugsweise so weit durch die äußeren Anschlußstutzen 8 hindurchgeführt, daß ihr herausgeführtes Ende 20 über das Ende 14 des zugehörigen äußeren Anschlußstutzens übersteht. Um auf einfache Weise eine Abdichtung mit anzuschließenden Einrichtungen zu erhalten, ist das Ende 20 mit einem Dichtungsring 21 versehen. In Fig. 1 ist ein Teil einer anzuschließenden Armatur 22 dargestellt, deren Innenrohr 23 auf dem inneren Anschlußstutzen 6 aufgesteckt ist. Der Dichtring 21 dichtet den Vorlauf gegenüber dem Rücklauf ab. Die Armatur 22 braucht lediglich mit einer Überwurfmutter 16 und einer Dichtungsscheibe 24 am Anschlußstutzen 8 befestigt zu werden.The inner connecting piece 6 are preferably passed so far through the outer connecting piece 8 that their end 20 protrudes beyond the end 14 of the associated outer connecting piece. In order to obtain a seal with devices to be connected in a simple manner, the end 20 is provided with a sealing ring 21. 1 shows part of a fitting 22 to be connected, the inner tube 23 of which is attached to the inner connecting piece 6. The sealing ring 21 seals the flow against the return. The valve 22 only needs to be attached to the connecting piece 8 with a union nut 16 and a sealing washer 24.

Fig. 1 zeigt eine konzentrische Anordnung der inneren Anschlußstutzen und eine Armatur 22, die ein entsprechend konzentrisch angeordnetes Innenrohr 23 hat. Bedingt durch Fertigungstoleranzen lassen sich Innenrohr 23 und Anschlußstutzen 6 nicht immer exakt konzentrisch anordnen, weshalb der innere Anschlußstutzen 6 eine gewisse Elastizität aufweist, damit er stets in die Position des Innenrohrs 23 verschoben werden kann. Vorzugsweise wird der innere Anschlußstutzen 6 als dünnwandiges Messingrohr gefertigt, welches die durch ein Verschieben des äußeren Endes 20 bedingten Biegespannungen aufnehmen kann.Fig. 1 shows a concentric arrangement of the inner connecting piece and a fitting 22 which has a correspondingly concentrically arranged inner tube 23. Due to manufacturing tolerances, inner tube 23 and connecting piece 6 cannot always be arranged exactly concentrically, which is why the inner connecting piece 6 has a certain elasticity so that it can always be moved into the position of the inner tube 23. Preferably, the inner connecting piece 6 is made as a thin-walled brass tube, which can absorb the bending stresses caused by moving the outer end 20.

Um die Einführung des inneren Anschlußstutzens 6 in das Innenrohr 23 zu erleichtern, kann das Ende 20 konisch ausgebildet sein.In order to facilitate the insertion of the inner connecting piece 6 into the inner tube 23, the end 20 can be conical.

Fig. 3 zeigt eine asymmetrische Anordnung der beiden zugeordneten Anschlußstutzen 6, 8. Diese Anordnung kann beispielsweise dann vorteilhaft sein, wenn Doppelrohre mit asymmetrischem Innenrohr angeschlossen werden sollen.Fig. 3 shows an asymmetrical arrangement of the two associated connecting pieces 6, 8. This arrangement can be advantageous, for example, if double pipes with an asymmetrical inner pipe are to be connected.

An den Enden 12, 14 kann eine Abdeckplatte 17 angebracht sein, die Löcher 18, 19 hat, von denen das eine Loch 18 in den inneren Anschlußstutzen 6 und das andere Loch 19 in den äußeren Anschlußstutzen 8 führt. Die Abdeckplatte 17 kann auch als Dichtung ausgeführt sein.At the ends 12, 14, a cover plate 17 can be attached, which has holes 18, 19, of which one hole 18 leads into the inner connection piece 6 and the other hole 19 into the outer connection piece 8. The cover plate 17 can also be designed as a seal.

Es wird noch angemerkt, daß die inneren Anschlußstutzen 6 vorzugsweise mittels Preßpassungen in den Öffnungen 5 befestigt sind. Die äußeren Anschlußstutzen 8 können ebenfalls mittels Preßpassungen gehalten werden, jedoch können sie auch zusätzlich zur Erhöhung der mechanischen Stabilität mit dem Gehäuse 1 verlötet oder verschweißt sein.It should also be noted that the inner connecting pieces 6 are preferably fastened in the openings 5 by means of press fits. The outer connecting pieces 8 can also be held by means of press fits, but they can also be soldered or welded to the housing 1 in order to increase the mechanical stability.
