Abstract
Description
Die Erfindung betrifft einen Losflansch für eine Flanschverbindung sowie eine Flanschverbindung.The The invention relates to a loose flange for a flange connection and a flange connection.
Aus
der
Eine
weitere Flanschverbindung mit zwei Losflanschen ist aus der
Die zuvor genannten Flanschverbindungen mit jeweils identisch aufgebauten Losflanschen erfordern eine parallele Lage der an den Rohrenden vorgesehnen Kragen. Liegt eine parallele Ausrichtung der Kragen nicht vor, können die Rohrenden bei Anziehen der Flanschverbindung beschädigt werden, und es besteht auch die Gefahr, dass die Flanschverbindung undicht bleibt.The previously mentioned flange connections each with identically constructed Loose flanges require a parallel position at the pipe ends foreshortened collar. Is a parallel alignment of the collar not before, the pipe ends when tightening the flange connection be damaged, and there is also a risk that the flange connection remains leaking.
Der Erfindung liegt die Aufgabe zugrunde, das Herstellen einer dichten Flanschverbindung auch bei nur mäßig ausgerichteten Rohrenden zu ermöglichen.Of the Invention is based on the object of producing a dense Flange connection even with only moderately aligned To enable pipe ends.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen der Ansprüche 1 bzw. 6.The Solution of this problem is inventively with the features of claims 1 and 6, respectively.
Gemäß der Erfindung ist bei einem Losflansch für eine Flanschverbindung gemäß dem Oberbegriff des Anspruchs 1 vorgesehen, dass mindestens eine der Sitzflächen eines ersten oder zweiten Losflanschteils derart ausgebildet ist, dass ein Verkippen der zu verbindenden Elemente möglich ist. Im Gegensatz zum Stand der Technik ist es somit nicht mehr erforderlich, zu verbindende Elemente, insbesondere Rohrenden exakt auszurichten.According to the The invention is in a loose flange for a flange connection according to the preamble of claim 1, that at least one of the seats of a first or second Losflanschteils is designed such that a tilting the elements to be connected is possible. In contrast the prior art, it is therefore no longer necessary to be connected Align elements, especially pipe ends exactly.
Gemäß einer besonders bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass mindestens eine der Sitzflächen als Ausgleichsfläche ausgebildet ist, wobei die Sitzflächen vorzugsweise Kegel- oder Kugelabschnittsflächen sind. Solche Sitzflächen erlauben es, gegebenenfalls auch unter Ausnutzung der Verformbarkeit anzuschließender Elementabschnitte auch größere Verkippwinkel bis 10°, insbesondere jedoch bis 2° zuzulassen.According to one particularly preferred embodiment of the invention is provided that at least one of the seats is formed as a compensation surface is, wherein the seating surfaces preferably cone or spherical section surfaces are. Such seats allow it, if necessary taking advantage of the deformability of the element sections to be connected also larger tilt angles up to 10 °, in particular however, to allow up to 2 °.
Gemäß weiterer bevorzugter Ausgestaltungen der Erfindung ist vorgesehen, dass an dem ersten Losflanschteil an dessen Enden eine erste bzw. zweite Schraubenaufnahme ausgebildet sind und dass an dem zweiten Losflanschteil an dessen Enden eine erste bzw. zweite Schraubenaufnahme sowie ferner vorzugsweise zwischen diesen, insbesondere mittig eine dritte Schraubenaufnahme ausgebildet sind. Dies erleichtert die Montage einer Flanschverbindung.According to others preferred embodiments of the invention is provided that on the first Losflanschteil at the ends of a first and second Screw receptacle are formed and that on the second Losflanschteil at the ends of a first and second screw receptacle and further preferably between these, in particular centrally a third screw receptacle are formed. This facilitates the installation of a flange connection.
Die Vorteile der Erfindung zeigen sich auch an einer Flanschverbindung mit einem ersten und einem zweiten Flansch, wenn der erste Flansch als Losflansch nach einem der Ansprüche 1 bis 5 ausgebildet ist. Daher wird auch für eine Flanschverbindung selbständig Schutz beansprucht.The Advantages of the invention are also evident in a flange connection with a first and a second flange when the first flange designed as a loose flange according to one of claims 1 to 5 is. Therefore, becomes independent for a flange connection Protection claimed.
Gemäß einer besonders bevorzugten Ausgestaltung der Flanschverbindung ist vorgesehen, dass der zweite Flansch als Festflansch insbesondere an einem Abgaskrümmer ausgebildet ist, wobei dessen Sitzfläche vorzugsweise als Ausgleichsfläche, insbesondere als Kegel- oder Kugelabschnittsfläche ausgebildet ist.According to one Particularly preferred embodiment of the flange connection is provided that the second flange as a fixed flange, in particular on an exhaust manifold is formed, wherein the seat preferably as Compensating surface, in particular as a conical or spherical section surface is trained.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung im Zusammenhang mit den Zeichnungen.Further yield advantageous embodiments and refinements of the invention from the subclaims as well as from the description in connection with the drawings.

Die gezeigte Konfiguration hat ferner den Vorteil dass sich bei Befestigung des größeren Flanschrings an dessen mittleren Schraubloch und Fixierung beider Flanschteile an einem weiteren Schraubloch sich eine Drehbarkeit des kleinen Flanschrings ergibt, was die Montage erleichtert.The shown configuration also has the advantage that when mounting of the larger flange ring at its middle Screw hole and fixation of both flange on another Screw hole results in a rotation of the small flange ring, which makes assembly easier.
