Description

Das Alldichten von Deckeln, z. 13. lief Hochdruckautoklaven, ist ein Problem, das nicht immer in technisch einfacher Weise zu lösen ist.The all-sealing of lids, e.g. 13. If high-pressure autoclaves were running, this is a problem that cannot always be solved in a technically simple manner.

Gegenstand derErfindung ist ein selbstdichtendes Element für mit Bajonettverschluß eingesetzte Deckel, z. B. bei Hochdruckautoklaven, dessen wesentliches Kennzeichen darin besteht, daß dieses Element die Form einer plattenförmigen, einmal gewellten -.Membran aufweist, deren Welle im Querschnitt die Gestalt eines Kreisbogens hat. Die Welle hat somit von vornherein die Gestalt, die sie unter hohem Druck einnimmt. Es treten daher in der Welle im wesentlichen nur tangentiale Beanspruchungen auf, die keine Formänderung des Kreisbogens hervorrufen. Infolgedessen können auch die Widerlager für die Welle der Kreisbogenform der Welle angepaßt werden, so daß die Welle an der Cbergangsstelle von ihrer gestützten zur ungestiitzten Lage keine Abbiegung erfährt. Die hr@ifte werden aufgenommen, so daß die Wandung selbst lief hohen Drucken schwach gehalten werden kann, zumal die \Vaiidstürke sich le<iinlich- nach dein Durchmesser der Meinl»-anwelle richtet und voll (lern lichten Durchmesscl- der zti verbindenden Teile (Deckel oder Apparatilialltel) vollkommen ull- abhangig ist. In der Zeichnung ist eine hcispielsweise Atts- führungsforin der 1?rtindung dargestellt. Dabei be- deutet ;i die Membran. 2 die Widerlager zur Auf- nahme der "I`angentialkr<ifte bzw. clie Festpunkte, «-elche die auszuglcichende Bewegung gegenein- ander ausführen, 3 die I:lementc zur Aufnahme der Axialkräfte. The subject of the invention is a self-sealing element for cover inserted with a bayonet lock, e.g. B. in high-pressure autoclaves, the main feature of which is that this element has the shape of a plate-shaped, once corrugated membrane, the cross-section of which has the shape of an arc of a circle. The wave thus has the shape from the start that it assumes under high pressure. There are therefore essentially only tangential stresses in the shaft that do not cause any change in the shape of the circular arc. As a result, the abutments for the shaft can also be adapted to the circular arc shape of the shaft, so that the shaft does not bend at the transition point from its supported to unsupported position. The clocks are recorded so that the wall itself ran high pressures to be kept weak can, especially since the Turkis le <iinlich- after your diameter of the Meinl »shaft aligns and full (learn clear diameter of the zti connecting Parts (cover or apparatus) completely empty is dependent. The drawing shows an example of Guide for the 1? direction shown. Thereby indicates; i the membrane. 2 the abutments for support take the "tangential forces" or the fixed points, "-Which movement to be compensated against- other perform, 3 the I: lementc to accommodate the Axial forces.
