Abstract

The cuff acts as an adaptor for providing a gas-tight connection between a flue pipe (8) and a chimney (1). A flange plate (6) has a central aperture (7) providing a pressure seat for the end of the flue pipe. The opening edge (9) is pivoted in the direction of the central longitudinal axis of the flue pipe. It can act as a sealing ring cooperating with the outer surface (11) of the flue pipe. The flange plate edge has a perpendicular cuff (12). This can fit over a connection opening (3) provided by the chimney, with a circular clamp (13) used to secure the cuff to the opening.

Description

Die Erfindung betrifft eine Anschlußmuffe zur gasdichten Verbindung einer Abgasleitung mit dem Rauchrohr eines Schornsteins gemäß dem Oberbegriff des Anspruchs 1. Eine derartige Muffe ist als Adapter beschrieben in der EP-A-0 672 866. Bei dieser vorbekannten Muffe besteht die Notwendigkeit, einen ringförmigen Stützkörper in den Anschlußstutzen des Rauchrohrs mit einbringen zu müssen. Wegen dieses Stützkörpers ist nur noch der vom Stützkörper freigelassene Anteil des Anschlußstutzendurchmessers für die Abgasleitung nutzbar. Da zusätzlich zwischen dem Stützkörper und dem Anschlußstutzen noch Dichtmaterial eingebracht sein muß, können nur Abgasleitungen mit sehr viel geringerem Durchmesser als dem Durchmesser des Anschlußstutzens des Rauchrohrs mit der bekannten Muffe befestigt werden. Dies ist insbesondere nachteilig, weil mit der bekannten Muffe keine Abgasleitungen eingesetzt werden können, die ähnlich geringe Strömungswiderstände wie das Rauchrohr des Schornsteins erreichen. Der vollständige Durchmesser des Anschlußstutzens läßt sich nach dem Stand der Technik also nicht annähernd für die anzuschließende Abgasleitung nutzen.The invention relates to a connecting sleeve for the gas-tight connection of an exhaust pipe to the flue pipe of a chimney according to the preamble of claim 1. Such a sleeve is described as an adapter in EP-A-0 672 866 . In this known sleeve there is a need to bring an annular support body into the connecting piece of the smoke pipe. Because of this support body, only the portion of the connecting piece diameter left free by the support body can be used for the exhaust gas line. Since sealing material must also be introduced between the support body and the connecting piece, only exhaust pipes with a much smaller diameter than the diameter of the connecting piece of the flue pipe can be attached with the known sleeve. This is particularly disadvantageous because, with the known sleeve, it is not possible to use exhaust pipes which achieve flow resistance that is similar to that of the flue pipe of the chimney. The full diameter of the connecting piece can therefore not be used anywhere near for the exhaust pipe to be connected according to the prior art.

Ein weiterer Nachteil ist das membranartige Verhalten des Dichtungsmaterials. Das Dichtungsmaterial kann deshalb nur über einen gewissen Grad verformt werden. Bei zu großer Verformung besteht die latente Gefahr des Einreißens des Dichtungsmaterials. Es können also mit einem Dichtungstyp nur relativ enge Durchmesserbereiche von Abgasleitungen abgedeckt werden.Another disadvantage is the membrane-like behavior of the sealing material. The sealing material can therefore only be deformed to a certain degree. If the deformation is too great, there is a latent risk of the sealing material tearing. Thus, only relatively narrow diameter ranges of exhaust pipes can be covered with one type of seal.

Ausgehend von diesen Nachteilen liegt der Erfindung die Aufgabe zugrunde, eine Anschlußmuffe so zu gestalten, daß ein möglichst großer Anteil des Durchmessers des Anschlußstutzens für die anzubringende Abgasleitung nutzbar ist und daß mit Hilfe eines Muffentyps ein möglichst großes Intervall von Abgasleitungsdurchmessern abdeckbar ist. Diese Aufgabe ist durch die Merkmalskombination des Anspruchs 1 gelöst.Based on these disadvantages, the invention has for its object to design a connecting sleeve so that the largest possible proportion of the diameter of the connection piece for the exhaust pipe to be attached is usable and that the largest possible interval of exhaust pipe diameters can be covered with the aid of a sleeve type. This object is achieved by the combination of features of claim 1.

Gemäß der Erfindung ist die Muffenfixierung aus dem Anschlußstutzeninnenraum heraus in den Bereich des Außenmantels des Anschlußstutzens verlegt. Die Muffe weist hierfür eine aus ihrem Grundkörper etwa rechtwinklig herausstehende Manschette auf, welche über den Außenmantel des am Rauchrohr angeformten Anschlußstutzens gestülpt ist. Mit der erfindungsmäßigen Anschlußmuffe ist es deshalb möglich, Abgasleitungen am Anschlußstutzen des Rauchrohrs anzubringen, deren Außendurchmesser nahezu dem Innendurchmesser des Anschlußstutzens entspricht. Auf diese Weise ist es möglich, Abgasleitungen zu verwenden, deren Strömungswiderstand ähnlich gering ist wie der Strömungswiderstand des Rauchrohrs.According to the invention, the sleeve fixing is moved out of the interior of the connecting piece into the area of the outer jacket of the connecting piece. For this purpose, the sleeve has a sleeve protruding approximately at right angles from its base body, which is put over the outer jacket of the connecting piece formed on the smoke tube. With the connecting sleeve according to the invention, it is therefore possible to attach exhaust pipes to the connecting piece of the flue pipe, the outer diameter of which corresponds almost to the inner diameter of the connecting piece. In this way it is possible to use exhaust pipes, the flow resistance of which is similarly low as the flow resistance of the flue pipe.

Vorteilhaft ist es, die Muffe am Anschlußstutzen klemmend zu fixieren, wie dies in Anspruch 2 vorgeschlagen ist. Eine besonders einfache und damit kostengünstige Klemmfixierung beinhaltet Anspruch 3, wonach eine handelsübliche Schlauch- bzw. Rohrschelle zur Klemmfixierung eingesetzt wird. Die Klemmfixierung hat zudem den Vorteil, daß die Passung Manschette-Anschlußstutzenaußenmantel nicht als Übergangspassung gestaltet sein muß, bei welcher die Manschette formschlüssig auf dem Anschlußstutzen aufgesetzt ist. Vielmehr kann diese Passung als Spielpassung ausgeführt sein, was die Montage der Muffe auf dem Anschlußstutzen erheblich erleichtert.It is advantageous to fix the sleeve to the connecting piece by clamping, as proposed in claim 2. A particularly simple and therefore inexpensive clamp fixation includes claim 3, according to which a commercially available hose or pipe clamp is used for clamp fixation. The clamp fixation also has the advantage that the fit of the sleeve-connecting piece outer jacket does not have to be designed as a transition fit, in which the sleeve is positively placed on the connecting piece. Rather, this fit can be designed as a clearance fit, which considerably facilitates the assembly of the sleeve on the connecting piece.

Die Dichtwirkung der Muffe gegenüber der in der Durchtrittsöffnung einliegenden Abgasleitung ist erheblich verbessert durch die Verwendung elastischen und gleichzeitig temperaturbeständigen Materials für den Muffengrundkörper nach der Lehre des Anspruchs 4. Die elastische Ausgestaltung des Muffengrundkörpers ermöglicht nämlich ein leichtes Verschwenken der Öffnungsränder der Durchtrittsöffnung in Mittellängsrichtung der Abgasleitung zur Bildung des dichtringartigen Anlagesitzes der Muffe an der Außenfläche der Abgasleitung.The sealing effect of the sleeve with respect to the exhaust pipe lying in the passage opening is considerably improved by the use of elastic and at the same time temperature-resistant material for the sleeve base body according to the teaching of claim 4. The elastic configuration of the sleeve base body enables the opening edges of the passage opening to be pivoted easily in the central longitudinal direction of the exhaust pipe to form the sealing ring-like contact seat of the sleeve on the outer surface of the exhaust pipe.

Fertigungstechnisch vorteilhaft ist es, nicht nur den Muffengrundkörper, sondern die gesamte Muffe gewissermaßen einteilig aus elastischem und temperaturbeständigem Material zu fertigen, wie dies in Anspruch 5 vorgeschlagen ist. Fertigungstechnisch günstig ist es auch, die Durchtrittsöffnung einfach aus dem Muffengrundkörper auszustanzen. Mit Hilfe des Ausstanzens lassen sich kostengünstig hohe Stückzahlen von Muffen in kurzer Zeit fertigen. Die Ansprüche 7 und 8 betreffen eine konsequente Weiterbildung dieser Stanzfertigung der Durchtrittsöffnung. Mit Hilfe der in Anspruch 7 vorgeschlagenen Schnittlinien ist es möglich, ein großes Intervall von Abgasleitungsdurchmessern abzudecken. Bei sehr kleinen Abgasleitungsdurchmessern ist die Abgasleitung hierbei einfach in die Durchtrittsöffnung eingeschoben, ohne daß die Schnittlinien in Funktion treten. Bei größeren Abgasleitungsdurchmessern wird die Durchtrittsöffnung durch Einschneiden der sternartig um die Durchtrittsöffnung gruppierten Schnittlinien in ihrem Durchmesser aufgeweitet und so auf den Außendurchmesser der Abgasleitung abgestimmt. Fertigungstechnisch vorteilhaft ist es, auch die Schnittlinien vorzustanzen. Das Vorstanzen der Schnittlinien kann bei entsprechender Werkzeugrüstung im selben Arbeitshub erfolgen wie das Ausstanzen der Durchtrittsöffnung.In terms of production technology, it is advantageous not only to manufacture the sleeve base body, but rather the entire sleeve in one piece from elastic and temperature-resistant material, as proposed in claim 5. It is also advantageous in terms of production technology to simply punch the passage opening out of the socket body. With the help of punching out, large quantities of sleeves can be manufactured inexpensively in a short time. Claims 7 and 8 relate to a consequent further development of this stamping production of the passage opening. With the help of the cutting lines proposed in claim 7, it is possible to cover a large interval of exhaust pipe diameters. In the case of very small exhaust pipe diameters, the exhaust pipe is simply pushed into the passage opening without the cutting lines functioning. In the case of larger exhaust pipe diameters, the diameter of the passage opening is widened by cutting the lines of intersection, which are grouped in a star shape around the passage opening, and thus matched to the outside diameter of the exhaust pipe. It is advantageous in terms of manufacturing technology to also pre-punch the cutting lines. With appropriate tooling, the cutting lines can be pre-punched in the same working stroke as the punched-out opening.

Die erfindungsmäßige Muffe eignet sich sowohl für Schornsteine im Unterdruckbetrieb, was dem Normalfall des Schornsteinbetriebs entspricht, als auch für Schornsteine im Überdruckbetrieb. Das Muffenmaterial ist üblicherweise bis zu einer Höchsttemperatur von 250°C geprüft und für einen Dauerbetrieb bei 200°C ausgelegt.The sleeve according to the invention is suitable both for chimneys in vacuum operation, which corresponds to the normal case of chimney operation, and for chimneys in overpressure operation. The sleeve material is usually tested up to a maximum temperature of 250 ° C and designed for continuous operation at 200 ° C.

Die Erfindung ist anhand des in der Zeichnung dargestellten Ausführungsbeispiels weiter erläutert.

Fig. 1
zeigt die Schnittdarstellung eines Anschlußbereichs eines Rauchrohrs mit Anschlußstutzen mit auf dem Anschlußstutzen klemmfixierter Muffe und einliegender Abgasleitung.
The invention is further explained on the basis of the exemplary embodiment shown in the drawing.
Fig. 1
shows the sectional view of a connection area of a flue pipe with a connection piece with a socket fixed to the connection piece and an inserted exhaust pipe.

Das in Fig. 1 nur teilweise dargestellte Rauchrohr 1 erstreckt sich in Vertikalrichtung 2. Vom Rauchrohr 1 geht schräg zur Vertikalrichtung 2 ab der Anschlußstutzen 3. Der Anschlußstutzen 3 dient beispielsweise zum Anschluß von Brennwertfeuerstätten an das Rauchrohr 1. Derartige Brennwertfeuerstätten sind beispielsweise in einzelnen Wohneinheiten angeordnete Thermen. Über den Außenmantel 4 des Anschlußstutzens 3 ist die Anschlußmuffe 5 gestülpt. Die Anschlußmuffe 5 besteht aus einer als Muffengrundkörper wirksamen Scheibe 6. Die Scheibe 6 ist in ihrer Mitte von der Durchtrittsöffnung 7 durchsetzt. In die Durchtrittsöffnung 7 ist die Abgasleitung 8 eingeschoben.The smoke pipe 1 shown only partially in Fig. 1 extends in the vertical direction 2. From the smoke pipe 1 goes obliquely to the vertical direction 2 from the connecting piece 3. The connecting piece 3 is used, for example, for connecting condensing fireplaces to the smoking pipe 1. Such condensing fireplaces are, for example, in individual residential units arranged thermal baths. The connecting sleeve 5 is slipped over the outer jacket 4 of the connecting piece 3. The connecting sleeve 5 consists of a disk 6 which acts as a sleeve base body. The disk 6 is penetrated in its center by the passage opening 7. The exhaust pipe 8 is inserted into the passage opening 7.

Zur verbesserten Gasdichtheit der Abgasleitung 8 im Bereich der Anschlußmuffe 5 sind die Öffnungsränder 9 in Mittellängsrichtung 10 der Abgasleitung 8 verschwenkt. Die Öffnungsränder 9 bilden so einen lippenförmigen Dichtring, welcher im Montageendzustand paßgenau und schlüssig an der Außenfläche 11 der Abgasleitung 8 anliegt. Der in der Zeichnungsfigur erkennbare Zwischenraum zwischen der Außenfläche 11 und den Öffnungsrändern 9 ist nur der zeichnerischen Klarheit halber vorhanden, existiert in der Realität jedoch nicht.For improved gas tightness of the exhaust gas line 8 in the area of the connecting sleeve 5, the opening edges 9 are pivoted in the central longitudinal direction 10 of the exhaust gas line 8. The opening edges 9 thus form a lip-shaped sealing ring which, in the final assembly state, fits snugly and coherently on the outer surface 11 of the exhaust pipe 8. The space between the outer surface 11 and the opening edges 9 which can be seen in the drawing figure is only present for the sake of clarity in the drawing, but does not exist in reality.

Aus der den Muffengrundkörper bildenden Scheibe 6 steht etwa rechtwinklig, also etwa in Mittellängsrichtung 10 der Abgasleitung 8 die Manschette 12 hervor. Die Manschette 12 ist im Montageendzustand der Anschlußmuffe 5 über das dem Rauchrohr 1 abgewandte Ende des Anschlußstutzens 3 so gestülpt, daß die Innenwände der Manschette 12 am Außenmantel 4 des Anschlußstutzens 3 anliegen. Zur Klemmfixierung der Manschette 12 ist die Rohrschelle 13 umlaufend um die Manschette 12 verspannt.The sleeve 12 protrudes from the disk 6 forming the socket body approximately at a right angle, that is to say approximately in the longitudinal direction 10 of the exhaust pipe 8. In the final assembly state of the connecting sleeve 5, the sleeve 12 is placed over the end of the connecting piece 3 facing away from the flue pipe 1 such that the inner walls of the sleeve 12 rest against the outer jacket 4 of the connecting piece 3. To clamp the sleeve 12, the pipe clamp 13 is clamped all around the sleeve 12.

In der Zeichnung dargestellt ist ein Anwendungsfall mit einer Abgasleitung 8, deren Außendruchmesser deutlich geringer ist als der Innendurchmesser des Anschlußstutzens 3. Wie aus der Zeichnung ersichtlich, verschwenken bei diesem Anwendungsfall die Öffnungsränder 9 beim Einschieben der Abgasleitung 8 in den Anschlußstutzen 3 hinein und liegen nach Art einer Dichtlippe ringförmig an der Außenfläche 11 der Abgasleitung 8 an.The drawing shows an application with an exhaust pipe 8, the outside diameter of which is significantly smaller than the inside diameter of the connecting piece 3. As can be seen from the drawing, in this application the opening edges 9 pivot when the exhaust pipe 8 is inserted into the connecting piece 3 and lie behind Kind of a sealing lip in a ring on the outer surface 11 of the exhaust pipe 8.

Bei einer mit der Erfindung ebenfalls realisierbaren Ausführungsform mit einem dem Innendurchmesser des Anschlußstutzens 3 im wesentlichen entsprechenden Außendurchmesser der Abgasleitung 8 erfolgt die Montage der Abgasleitung 8 an der Anschlußmuffe 5 derart, daß die Abgasleitung 8 vom später dem Rauchrohr 1 zugewandten Ende her in die Anschlußmuffe 5 eingeschoben wird. Auf diese Weise sind die Öffnungsränder 9 im späteren Montageendzustand nicht in den Anschlußstutzen 3 hineinverschwenkt, sondern liegen dem Anschlußstutzen 3 abgewandt ebenfalls an der Außenfläche 11 der Abgasleitung 8 an. Auf diese Weise entfällt der Raumbedarf für die Öffnungsränder 9 zwischen der Innenfläche des Anschlußstutzens 3 und der Außenfläche der Abgasleitung 8. Auf diese Weise ist der Innendurchmesser des Anschlußstutzens 3 vollständig zur Aufnahme der Abgasleitung 8 nutzbar.In an embodiment which can also be realized with the invention and which has an outer diameter of the exhaust pipe 8 which essentially corresponds to the inside diameter of the connecting piece 3, the exhaust pipe 8 is mounted on the connecting sleeve 5 such that the exhaust pipe 8 from the end which later faces the smoke pipe 1 into the connecting sleeve 5 is inserted. In this way, the opening edges 9 are not pivoted into the connecting piece 3 in the later final assembly state, but are also facing away from the connecting piece 3 on the outer surface 11 of the exhaust pipe 8. In this way, the space required for the opening edges 9 between the inner surface of the connecting piece 3 and the outer surface of the exhaust pipe 8 is eliminated. In this way, the inner diameter of the connecting piece 3 is completely usable for receiving the exhaust pipe 8.
