Description

Dichtungsring Gegenstand der Erfindung ist ein Dichtungsring aus einer Metallscheibe mit auf beiden Ringseiten angeordneten konzentrischen Ringnuten, die mit Weichstoff ausgefüllt sind.Sealing ring The invention is a sealing ring from a Metal disc with concentric annular grooves arranged on both sides of the ring, the are filled with soft material.

Für die Abdichtung von Rohrverbindungen ist es bekannt, Dichtungsringe mit einem metallischen Träger zu verwenden, der auf beiden Seiten konzentrische Ringnuten aufweist, in denen graphitierte Asbestschnüre oder auch Metalldrähte eingelegt sind. Dadurch wird das Abdichten der beiden Flansche wesentlich erleichtert. Solche Dichtungen bestehen oft aus einem dünnen Metallblech, in das die konzentrischen Ringnuten eingepreßt sind. Außer der Verwendung von Asbestschnüren und Metalldrähten als Auskleidewerkstoff wurde auch bereits eine plastische Masse, die in der Hauptsache aus Graphit bestand, in die Nuten eingearbeitet. Trotz der großen Betriebssicherheit solcher Dichtungen hat es sich insbesondere bei der Abdichtung von unter hohem Druck stehenden Gasen gezeigt, daß sie nicht immer voll befriedigen. Während die mit Asbest gefüllten Dichtungsringe das abzudichtende Gas durchlassen, sind die mit einem Graphit-Kunstharz-Gemisch ausgefüllten Dichtungsringe nicht ausreichend wärmebeständig und die Metalldrähte nicht elastisch genug bzw. nur bei hoher Dichtpressung anwendbar.Sealing rings are known for sealing pipe connections to use with a metallic support that is concentric on both sides Has annular grooves in which graphitized asbestos cords or metal wires are inserted are. This makes sealing the two flanges much easier. Such Seals often consist of a thin sheet of metal in which the concentric Annular grooves are pressed in. Except for the use of asbestos cord and metal wire as a lining material was already a plastic mass, which in the main consisted of graphite, incorporated into the grooves. Despite the great operational reliability Such seals have proven particularly useful when sealing under high pressure standing gases have shown that they are not always fully satisfactory. While those with asbestos Filled sealing rings allow the gas to be sealed through, those with a graphite-synthetic resin mixture Filled sealing rings are not sufficiently heat-resistant and the metal wires not elastic enough or only applicable with high sealing pressure.

Gemäß der Erfindung wird vorgeschlagen, mindestens eine Nut mit einer Gummi- oder Kunststoffschnur auszulegen und die übrigen Nuten, vorzugsweise die durchmessergrößten, mit Asbest bzw. mit Asbestschnüren auszufüllen. Diese Gummi-Asbest-Kombination hat den Vorteil, daß die größtenteils im Erdreich verlegten Leitungen auch zur Förderung von brennbaren Gasen verwendet werden können, da die äußeren Asbestschnüre gegen Feuer unempfindlich sind, die Gummischnüre jedoch eine ausreichende Gasdichtigkeit gewährleisten. Um ein Herausfallen der Dichtungsschnüre vor dem Einbau zu vermeiden, ist es vorteilhaft, diese einzukleben. Ferner ist es denkbar, die gesamte Dichtung zusätzlich mit einer Graphitmasse zu überziehen, um eine Feinabdichtung sicherzustellen. In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt.According to the invention it is proposed at least one groove with a Lay out rubber or plastic cord and the remaining grooves, preferably the largest in diameter to be filled in with asbestos or asbestos cord. This rubber-asbestos combination has the advantage that the lines, which are mostly laid in the ground, are also used for promotion of flammable gases can be used as the outer asbestos cords against Fire are insensitive, but the rubber cords are sufficiently gas-tight guarantee. To prevent the sealing cords from falling out before installation, it is advantageous to glue them in place. It is also conceivable that the entire seal additionally coated with a graphite compound to ensure a fine seal. In the drawing, the invention is shown using an exemplary embodiment.

In dem Dichtungsblech 1 sind konzentrische Ringnuten eingeprägt, in die Asbestschnüre 2 und Gummischnüre 3 eingelegt sind. Die Gummischnüre 3 liegen im mittleren Bereich der Dichtung, um gegen äußere Temperaturen durch die Asbestschnüre geschützt zu sein.In the sealing plate 1 concentric annular grooves are embossed, in the asbestos cords 2 and rubber cords 3 are inserted. The rubber cords 3 lie in the middle area of the seal to protect against external temperatures through the asbestos cords to be protected.
