Beschreibung description
Die Erfindung betrifft eine Dichtungsanordnung, welche miteinander zu verbindende, stumpf aneinanderstoßende Rohre, Fittings oder Gehäuse für gasförmige und flüssige Medien aufweist. The invention relates to a sealing arrangement which has butt-jointed pipes, fittings or housings for gaseous and liquid media to be connected to one another.
Aufgabe der Erfindung ist es, am Innendurchmesser der zu verbindenden Rohre oder dgl. abzudichten, wobei Toträume an der Stoßstelle der beiden Rohre vermieden werden sollen. The object of the invention is to seal on the inside diameter of the pipes to be connected or the like. Dead spaces at the joint of the two pipes are to be avoided.
Erfindungsgemäß wird dies dadurch erreicht, daß zwischen den Stirnflächen der aneinanderstoßenden Rohre, Fittings oder Gehäuse ein Dichtring angeordnet ist, der aus einem Stützwulst und einem an diesem angeformten und radial einwärts gerichteten Dichtwulst gebildet ist. According to the invention, this is achieved in that a sealing ring is arranged between the end faces of the abutting pipes, fittings or housing, which is formed from a support bead and a sealing bead formed thereon and directed radially inward.
Der Stützwulst kann Kreisquerschnitt oder Rechteckquerschnitt haben. The support bead can have a circular cross section or a rectangular cross section.
Die Querschnittsfläche des Stützwulstes beträgt vorzugsweise ein Mehrfaches der Querschnittsfläche des Dichtwulstes. The cross-sectional area of the support bead is preferably a multiple of the cross-sectional area of the sealing bead.
Zur Aufnahme des Dichtringes sind in den Stirnflächen der beiden aneinanderstoßenden Rohre dem Querschnitt des Dichtringes entsprechende Ausnehmungen ausgebildet. To accommodate the sealing ring, recesses corresponding to the cross section of the sealing ring are formed in the end faces of the two abutting tubes.
Vorzugsweise ist die innere Umfangsfläche des Dichtwulstes bündig mit den Innenwänden der abzudichtenden Rohre. The inner peripheral surface of the sealing bead is preferably flush with the inner walls of the pipes to be sealed.
Der Dichtring ist axial vorgespannt, wobei der schmale Dichtwulst radial durch den großvolumige-ren Stützwulst abgestützt ist. The sealing ring is axially pretensioned, the narrow sealing bead being supported radially by the large-volume support bead.
Eine beispielsweise Ausführungsform der Erfindung wird nachfolgend anhand der einzigen Figur der Zeichnung beschrieben, die im Schnitt zwei miteinander verbundene Rohrenden zeigt, die durch die erfindungsgemäße Dichtungsanordnung abgedichtet sind. An exemplary embodiment of the invention is described below with reference to the single figure of the drawing, which shows in section two interconnected pipe ends which are sealed by the sealing arrangement according to the invention.
Die in der Figur dargestellte Dichtungsanordnung 10 dient zum Abdichten zweier stumpf aneinanderstoßender Rohre 12, 14. In der dargestellten Ausführungsform sind die Rohre mit einer Kunststoffauskleidung 16 versehen. The sealing arrangement 10 shown in the figure serves to seal two butt-jointed tubes 12, 14. In the embodiment shown, the tubes are provided with a plastic lining 16.
Jedes der beiden Rohrenden ist mit einem konischen, auswärts gerichteten Flansch 18 versehen, ebenso haben die beiden Auskleidungen 16 an ihren Enden einen entsprechenden konischen Flansch 20, wobei die Flansche 20 den Flanschen 18 angepaßt sind und in diese radial auswärts hineinragen, derart, daß die Flansche 18 der Rohre 12 die Flansche 20 der Auskleidung 16 umgreifen. Each of the two tube ends is provided with a conical, outwardly directed flange 18, likewise the two liners 16 have a corresponding conical flange 20 at their ends, the flanges 20 being adapted to the flanges 18 and projecting radially outward into them such that the Flanges 18 of the tubes 12 encompass the flanges 20 of the lining 16.
Die Flansche 18 der beiden Rohre 12 werden durch eine Muffe 38 axial gegeneinander gepreßt und koaxial zueinander gehalten. The flanges 18 of the two tubes 12 are pressed axially against one another by a sleeve 38 and are held coaxially with one another.
Die Muffe 38 hat hierzu einwärts gerichtete Flansche 40 mit Innenkonus, der dem Außenkonus der Flansche 18 der Rohre 12 angepaßt ist. For this purpose, the sleeve 38 has inwardly directed flanges 40 with an inner cone which is adapted to the outer cone of the flanges 18 of the tubes 12.
Die beiden Rohrenden können aber auch übliche zylindrische Flansche haben, die durch parallel zur Mittelachse der Rohre verlaufende Schrauben axial verbunden und zusammengepreßt werden. The two tube ends can also have conventional cylindrical flanges which are axially connected and pressed together by screws running parallel to the central axis of the tubes.
Zwischen den Stirnflächen 22 der Auskleidungen 16 ist ein Dichtring angeordnet, wobei die Figur zwei verschiedene Ausführungsformen eines solchen Dichtringes zeigt, d.h. in der oberen Hälfte der Figur ist ein Dichtring 26 mit im wesentlichen rechteckigem Querschnitt und in der unteren Hälfte der Figur ist ein Dichtring 28 mit im wesentlichen Kreisquerschnitt dargestellt. A sealing ring is arranged between the end faces 22 of the linings 16, the figure showing two different embodiments of such a sealing ring, i.e. in the upper half of the figure is a sealing ring 26 with an essentially rectangular cross section and in the lower half of the figure a sealing ring 28 with an essentially circular cross section is shown.
Der Dichtring 26 besteht aus einem Grundkörper oder Stützwulst 30, an den ein radial einwärts gerichteter Dichtwulst 34 angeformt ist. Entsprechend besteht der Dichtring 28 aus einem Grundkörper oder Stützwulst 32, an den ebenfalls ein radial einwärts gerichteter Dichtwulst 34 angeformt ist. The sealing ring 26 consists of a base body or support bead 30, on which a radially inwardly directed sealing bead 34 is formed. Correspondingly, the sealing ring 28 consists of a base body or support bead 32, on which a radially inwardly directed sealing bead 34 is also formed.
Die Querschnittsfläche der Stützwulste 30 und 32 beträgt ein Mehrfaches der Querschnittsfläche des zugehörigen Dichtwulstes 34. Beispielsweise kann sowohl die axiale Länge als auch die radiale Breite des Stützwulstes 30 bzw. 32 etwa das Fünffache der axialen Länge bzw. der radialen Breite des Dichtwulstes 34 betragen. The cross-sectional area of the support beads 30 and 32 is a multiple of the cross-sectional area of the associated sealing bead 34. For example, both the axial length and the radial width of the support bead 30 or 32 can be approximately five times the axial length or the radial width of the sealing bead 34.
In der dargestellten Ausführungsform hat der Dichtwulst 34 des Dichtringes 28 etwa Rechteckquerschnitt, während der Dichtwulst 34 des Dichtringes 26 einen konischen Querschnitt hat, wobei sich eine axiale Breite radial nach innen verringert. In the illustrated embodiment, the sealing bead 34 of the sealing ring 28 has an approximately rectangular cross-section, while the sealing bead 34 of the sealing ring 26 has a conical cross-section, with an axial width decreasing radially inwards.
Beim Zusammenbau der beiden Rohrenden werden die Dichtringe axial zusammengepreßt, so daß sie unter axialer Vorspannung stehen. When assembling the two pipe ends, the sealing rings are pressed together axially so that they are under axial prestress.
Die innere Umfangsfläche 36 des Dichtwulstes 34 ist hierbei, wie dargestellt, bündig mit der Innenwand der Rohre 12 bzw. der Auskleidung 16, um die Bildung von Toträumen zu vermeiden und damit die Ablagerung von Bakterien oder anderen schädlichen Stoffen zu verhindern. The inner peripheral surface 36 of the sealing bead 34 is, as shown, flush with the inner wall of the tubes 12 or the lining 16 in order to avoid the formation of dead spaces and thus to prevent the deposition of bacteria or other harmful substances.
