Die Neuerung betrifft eine Dichtunpseinrichtung zum Abdichten von miteinander zu verbindenden stumpf aneinanderstoßenden Rohren, Fittings oder Gehäusen oder dgl. für gasförmige und flüssige Medien.The innovation concerns a sealing device for sealing butt-jointed pipes, fittings or housings or the like for gaseous and liquid media.
Aufgabe der Neuerung ist es am Innendurchmesser der zu verbindenden Rohre oder dgl. abzudichten, wobei Toträume an der Stoßstelle der beiden Rohre vermieden werden sollen.The purpose of the innovation is to seal the inner diameter of the pipes or similar to be connected, whereby dead spaces at the joint between the two pipes are to be avoided.
Neuerungsgemäß wird dies dadurch erreicht, daß zwischen den Stirnflächen der aneinanderstoßenden Rohre ein Dichtring angeordnet ist, der aus einem Stützwulst und einem an diesem angeformten und radial einwärts gerichteten Dichtwulst gebildet ist.According to the innovation, this is achieved by arranging a sealing ring between the end faces of the abutting pipes, which is formed from a supporting bead and a sealing bead formed on this and directed radially inwards.
Die Querschnittsfläche des Stützwulstes beträgt vorzugsweise ein Mehrfaches der Querschnittsfläche des Dichtwulstes.The cross-sectional area of the supporting 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 Rühre 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 stirrers.
Vorzugsweise ist die innere Umfangsflache des Dichtwulstes bündig mit den Innenwänden der abzudichtenden Rohre.Preferably, the inner peripheral surface of the sealing bead is flush with the inner walls of the pipes to be sealed.
Der Dichtring ist axial vorgespannt, wobei der schmale Dichtwulst radial durch den großvolumigeren Stlitzwulst abgestützt ist.The sealing ring is axially preloaded, with the narrow sealing bead being supported radially by the larger-volume slotted bead.
Eine beispielsweise Ausführungsform der Neuerung wird nächfolö.ercd anhand der einzigen Figur der Zeichnung beschrieben, die im Schnitt zwei miteinander verbundene Rohrenden zeigt, die durch Üe rteuerungsgemäße Dichtungseinrichtung abgedichtet sind,An example embodiment of the innovation is described below using the only figure in the drawing, which shows in section two interconnected pipe ends that are sealed by a sealing device according to the invention.

Die in der Figur dargestellte DichtünriseiiiriGhtung 1Ö dient zum Abdichten zweier stumpf aneinanderstoßender Rohre 12, 14, in der dargestellten ÄusfÜhrungsfcrm sind die Rohre mit einer Kunststoffauskleidung 16 versehen.The sealing device 10 shown in the figure serves to seal two butt-fitting pipes 12, 14. In the embodiment shown, the pipes are provided with a plastic lining 16.
jedes der beiden Rohrenden ist mit einem konischenj auswärts gerichteteneach of the two pipe ends is provided with a conical outward-facing
den Flanschen 18 angepaßt sind und in diese radial auswärts hineinragen,are adapted to the flanges 18 and project radially outwards into them, derart, däp die Flansche 18 der Röhre 12 die Flansche 20 aer Auskleidungsuch that the flanges 18 of the tube 12 the flanges 20 of the lining 16 umgreifen.16 encompass.
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 pipes 12 are pressed axially against each other by a sleeve 38 and held coaxially to each other.
Die Muffe 38 hat hierzu einwärts gerichtete Flansche 40 mit Innenkonus, der dem Außenkonus der Flansche 18 der Rohre 12 abgepaßt istä 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 pipes 12 ä
Die beiden Rohrenden können aber auch übliche zylindrische Flanschen haben, die durch parallel zur Mittelachse der Rohre verlaufende Schrauben axial verbunden und zusammengepreßt werden.The two pipe ends can also have conventional cylindrical flanges that are axially connected and pressed together by screws running parallel to the central axis of the pipes.
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, ie in the upper half of the figure a sealing ring 26 with a substantially rectangular cross section is shown and in the lower half of the figure a sealing ring 28 with a substantially 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 Gründkörper öder Stütz-Wulst 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, onto which a radially inwardly directed sealing bead 34 is formed. Accordingly, the sealing ring 28 consists of a base body or support bead 32, onto 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. BeispielsweiseThe cross-sectional area of the support beads 30 and 32 is a multiple of the cross-sectional area of the corresponding sealing bead 34. For example,
* ■ ♦ * 4 · · 4* ■ ♦ * 4 · · 4
■ · * * * ItMi * I 4 ■ · * * * ItMi * I 4
■ * J Oi .&igr; · · · ♦ * 6 j e·? Cf * tv■ * J Oi .&igr; · · · ♦ * 6 j e·? Cf * tv
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.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 &eacgr;&dgr; etwa Rechteckquerschnitt während der Dichtwulst 34 des Dichte ringes 26 einen konischen Querschnitt hat, wobei sich seine axiale Breite radial nach innen verringert.In the embodiment shown, the sealing bead 34 of the sealing ring 26 has an approximately rectangular cross-section, while the sealing bead 34 of the sealing ring 26 has a conical cross-section, with its axial width decreasing radially inward.
Beim Zusammenbau der1beiden 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 preload.
Die innere ümfartgsfläche 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 surrounding surface 36 of the sealing bead 34 is, as shown, flush with the inner wall of the pipes 12 or the lining 16 in order to avoid the formation of dead spaces and thus prevent the deposition of bacteria or other harmful substances.
