Description

Titel Dichtung unter Verwendung von MetalL und anderen plastisch verformbaren Materialien, die beliebig oft wieder verwendet werden kann.Title seal using metal and other plastically deformable Materials that can be reused as often as you like.

Anwendungsgebiet Die Erfindung betrifft eine Dichtung für Verbindungen und Verschlußstellen an Rohren, Behältern und Maschinen mittels Metall und anderer plastisch verformbarer Materialien, bei dem die verformten Dichtungselemente beliebig oft wiederverwendet werden können.Field of application The invention relates to a seal for connections and closures on pipes, containers and machines by means of metal and others plastically deformable materials, in which the deformed sealing elements are arbitrary can be reused many times.

Zweck Metalldichtungen werden verwendet für Verbindungen, die extremen Temperaturen oder Drücken sowie chemischer Einwirkung oder Strahlungseinflüssen ausgesetzt sind. Derartige Verbindungen werden benötigt in Ultrahochvakuumanlagen, iiochdruckanlagen, Atomreaktoren und in der chemischen Industrie.Purpose metal seals are used for connections that are extreme Temperatures or pressures as well as chemical effects or radiation influences are exposed. Such connections are required in ultra-high vacuum systems, high pressure plants, nuclear reactors and in the chemical industry.

Stand der Technik und Kritik Bei allen bisher verwendeten Dichtungen wird das Dichtelement durch die beim Dichtvorgang auftretende plastische Verformung für eine Wiederverwendung unbrauchbar, wodurch das Dichtverfahren insbesondere bei Verwendung von Edelmetallen unwirtschaftlich wird.State of the art and criticism For all seals used so far the sealing element becomes through the plastic deformation occurring during the sealing process unusable for reuse, whereby the sealing process in particular Use of precious metals becomes uneconomical.

Lösung und Prinzip Gelöst wird das Problem dadurch, daß eine zur Aufnahme des Dichtelements dienende Nut so ausgestaltet ist, daß das verformte Dichtelement nach Drehung um 1800 um einen seiner Durchmesser eine Querschnittsform aufweist, die nicht mit der Nutform übereinstimmt, so daß das Dichtelement beliebig oft wiederverwendet werden kann.Solution and principle The problem is solved by having one for recording of the sealing element serving groove is designed so that the deformed sealing element has a cross-sectional shape after rotation by 1800 about one of its diameter, which does not match the shape of the groove, so that the sealing element can be reused as often as required can be.

Das Prinzip der Erfindung wird an Hand von Fig.1 erklärt. Dort werden die zu verbindenden Teile 1 und 2 mit der Dichtung 3 in einer dreieckförmigen Nut gedichtet. Das ursprünglich im Querschnitt kreisrunde Dichtelement paßt sich beim Aufbringen der Flanschkräfte der Nut an, wobei als Dichtflächen die Flächen a,b und c wirken. Nach dem Lösen der Verbindung hat das Dichtelement die in Fig.2 gezeigte Form. Dreht man nun das verformte Dichtelement um seinen in der Zeichenebene liegenden Durchmesser um 1800 erhält man den Dichtring in der in Fig.3 gezeichneten tage. Nachdem eine etwaige Ealtverfestigung durch Glühen rückgängig gemacht wurde, wird das Dichtelement beim Aufbringen der Flanschkräfte so in die Nut gepreßt, daß erneut an den Flächen a,b und c gedichtet wird. Da sich das Dichtelement bei diesem Dichtvorgang wieder der Nut anpaßt, erhält man wieder die in Fig.1 dargestellte Anordnung. Da dieser Vorgang unbegrenzt wiederholbar ist, kann die Dichtung beliebig oft verwendet werden.The principle of the invention is explained with reference to FIG. There will be the parts to be connected 1 and 2 with the seal 3 in one triangular Sealed groove. The originally circular in cross-section sealing element fits when the flange forces are applied to the groove, the surfaces being used as sealing surfaces a, b and c work. After loosening the connection, the sealing element has the in Fig.2 shown shape. If you now rotate the deformed sealing element around its in the plane of the drawing If the diameter is around 1800, the sealing ring in the one shown in FIG. 3 is obtained days. After any hardening has been reversed by annealing, the sealing element is pressed into the groove when the flange forces are applied so that is sealed again on surfaces a, b and c. Since the sealing element in this If the sealing process adapts again to the groove, the one shown in FIG. 1 is obtained again Arrangement. Since this process can be repeated indefinitely, the seal can be made as desired often used.

Andere Lösungen Verschiedene Ausgestaltungen der Erfindung werden an Hand von Fig.4,5,6,?und8beschneben. Während die vorher beschriebene Verbindung positive und negative Flansche aufweist, wird nun in Fig.5 eine Verbindung mit gleichen (sexless) Flanschen beschrieben. In dieser Verbindung wird die Unsymmetrie der Nut durch den Zentrierring 4 erzeugt. In Fig.6 ist gezeigt, wie die Dichtung der vorliegenden Erfindung zur kraftschlüssigen, dichten Verbindung von Flansch und Rohr verwendet werden kann bzw. wie es die Schweißverbindung zwischen zwei Rohren ersetzen kann. Die Flansche 1 und 2 werden mittels Schrauben so auf das Zwischenstück 4 gedrückt, daß an den Flächen a,b und c gedichtet wird und die Rohre 5 und 6 dicht miteinander verbunden werden. In Fig.7 ist gezeigt, wie die Dichtung der vorliegenden Erfindung zur dichten und kraftschlüssigen Verbindung von Rohren mit Behältern verwendet werden kann. Der auf dem Rohr gleitende Flansch 1 enthält eine unsymmetrische Nut, die das Dichtelement aufnimmt, welches die Dichtung zwischen Behälter 2 und Rohr 4 übernimmt0 Die in Fig.8 gezeigte Dichtung ist ein Sonderfall der Fig.6 .Other solutions Various embodiments of the invention can be made with reference to Fig. 4,5,6,? and 8beschneben. While the previously described connection has positive and negative flanges, a connection with the same is now shown in FIG (sexless) flanges. In this connection the asymmetry of the groove generated by the centering ring 4. In Fig.6 it is shown how the seal of the present Invention used for the frictional, tight connection of flange and pipe and how it can replace the welded connection between two pipes. The flanges 1 and 2 are pressed onto the intermediate piece 4 by means of screws, that is sealed on the surfaces a, b and c and the tubes 5 and 6 tightly together get connected. In Fig.7 it is shown how the Seal of the present Invention used for tight and non-positive connection of pipes with containers can be. The flange 1 sliding on the pipe contains an asymmetrical groove, which receives the sealing element, which the seal between container 2 and pipe 4 takes over 0 The seal shown in Fig. 8 is a special case of Fig. 6.
