Description
Die Erfindung betrittl ein Verfahren zum vielmaligen Wiederverwenden eines Dichtelements aus plastisch verformbarem Material, das zur Herstellung der Abdichtung in eine Aufnahmenut von einer gegenüber einer durch die Dichtfläche verlaufenden Ebene unsymmetrischen Querschnittsform eingepreßt wird. Solche Abdichtungen werden verwendet bei Verbindungen und Verschlußstelleii an Rohren. Behältern und Maschinen Sie w"den verwendet, wenn sie extremen Temperaturen oder Drücken sowie chemischen Einwirkungen oder süvhlungseinflüssen ausgesetzt sind. Derartige Verbindungen werden benötigt in Ultrahochvakuumanlagen, Hochdruckanlagen, Atomreaktoren und in der chemischen Industrie.The invention enters a process for multiple times Reusing a sealing element made of plastically deformable material that is used for production the seal in a receiving groove of one opposite one running through the sealing surface Plane asymmetrical cross-sectional shape is pressed. Such seals are used at Connections and closure point on pipes. Containers and machines you would be used to, though they are exposed to extreme temperatures or pressures as well as chemical effects or the effects of cold are. Such connections are required in ultra-high vacuum systems, high pressure systems, Nuclear reactors and in the chemical industry.
Bei den bisher verwendeten Dichtungen wird das Dichtelement infolge der beim Dichtvorgang auftretenden plastischen Verformung nicht wiederverwendet, wodurch das Dichtverfahren insbesondere bei Verwendung von Edelmetallen unwirtschaftlich wird.In the previously used seals, the sealing element is due to the occurring during the sealing process plastic deformation is not reused, thereby reducing the sealing process in particular Use of precious metals becomes uneconomical.
Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, das die vielmalige Wiederverwendung von plastisch verformten Dichtringen ermöglicht.The object of the invention is therefore to provide a method that allows multiple reuse made possible by plastically deformed sealing rings.
Gelöst wird diese Aufgebe dadurch, daß das verformte Dichtelement für seine Wiederverwendung jeweils um 180° gedreht in die Aufnahinenut eingepreßt wird.This problem is solved in that the deformed sealing element is rotated by 180 ° and pressed into the receiving groove for its reuse.
Durch die Drehung des verformten Dichtelements um 180° stimmt die Querschnittsform des Dichtringes nicht mehr mit dem Querschnitt der Aufnahmenut überein, so daß der Dichtring erneut zur Erzielung einer Abdichtung plastisch verformt werdenBy rotating the deformed sealing element by 180 °, the cross-sectional shape of the sealing ring no longer corresponds to the cross-section of the receiving groove, so that the sealing ring is plastically deformed again to achieve a seal
ίο kann, wobei dieser Vorgang beliebig oft wiederholbar ist.ίο can, whereby this process can be repeated as often as required.
Die Erfindung ist nachstehend an Hand der Zeichnungen näher erläutert. Es zeigt F i g. 1 eine Flanschverbindung mit plastisch verThe invention is explained in more detail below with reference to the drawings. It shows F i g. 1 a flange connection with plastically ver formtem Dichtelement,molded sealing element,
F i g. 2 das verformte Dichtelement nach F i g. I F i g. 3 die Flanschverbindung nach F i g. 1 mit um 180° gedrehtem Dichtelement vor dem Verspannen, Fig.4 eine Flanschverbindung mit gleichartigen Flanschen. F i g. 2 the deformed sealing element according to FIG. I F i g. 3 the flange connection according to FIG. 1 with the sealing element rotated by 180 ° before bracing, FIG. 4 a flange connection with similar flanges.
Nach F i g. 1 werden die zu verbindenden Flanschen 1 und2 mit der Dichtung3 z.B. 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 α, b und c wirken. Nach dem Lösen der Verbindung hat das Dichtelement die in F i g. 2 gezeigte Form. Dreht man nun das verformte Dichtelement um seinen in der Zeichenebene liegenden Durchmesser um 180°, so erhält man den Dichtring in der in Fig. 3 gezeichneten Lage. Nachdem eine etwaige Kaltverfestigung durch Glühen rückgängig gemacht wurde, wird das Dichtelement beim Aufbringen der Flanschkräfte so in die Nut ge preßt, daß erneut an den Flächen a, b und c gedichtet wird. Da sich das Dichtelement bei diesem Dichtvorgang der Nut anpaßt, erhält man wieder die in F i g. 1 dargestellte Anordnung. Dieser Vorgang ist beliebig oft wiederholbar.According to FIG. 1 the flanges 1 and 2 to be connected are sealed with the seal 3, for example in a triangular groove. The originally circular in cross-section sealing element adapts to the groove when the flange forces are applied, the surfaces α, b and c acting as sealing surfaces. After the connection has been released, the sealing element has the functions shown in FIG. 2 shape shown. If the deformed sealing element is now rotated by 180 ° around its diameter lying in the plane of the drawing, the sealing ring is obtained in the position shown in FIG. 3. After any work hardening has been reversed by annealing, the sealing element is pressed into the groove when the flange forces are applied so that the surfaces a, b and c are again sealed. Since the sealing element adapts to the groove during this sealing process, the values shown in FIG. 1 shown arrangement. This process can be repeated as often as required.
Eine andere Ausgestaltung der Erfindung wird an Hand von F i g. 4 beschrieben. Während die vorher beschriebene Verbindung positive und negative Flansche aufweist, wird nun in F i g. 4 eine Verbindung mit gleichen Flanschen beschrieben. In dieser Verbindung wird die Unsymmetrie der Nut durch den Zentrierring4 erzeugt.Another embodiment of the invention is illustrated with reference to FIG. 4 described. While the connection previously described has positive and negative flanges, FIG. 4 describes a connection with the same flanges. In this connection, the asymmetry of the groove is generated by the centering ring 4 .
