Die Erfindung betrifft eine Membran-Schweißdichtung an Hochdruckapparaten, bestehend aus zwei zwischen den Flanschen eingespannten und an je einen Flansch angeschweißten Anschlußringen, von denen jeder an seiner dem Apparateinneren zugewandten Seite eine Hälfte der im Querschnittsprofil kreisringförmigen, auf ihrem inneren Umfang zusammengeschweißten Membran trägt.The invention relates to a membrane welding seal on high-pressure apparatus, consisting of two connecting rings clamped between the flanges and welded to one flange each, each of which on its side facing the interior of the apparatus is one half of the cross-sectional profile annular membrane welded together on its inner circumference.
Wenn bei einer derartigen Membran-Schweißdichtung die Flansche im Betrieb unterschiedliche Tem- ίο peraturen annehmen, so führen sie Relativbewegungen aus, die insbesondere bei großen Flanschdurchmessern zur Zerstörung der Membran führen können.If, with such a membrane welded seal, the flanges have different tem- ο during operation assume temperatures, they perform relative movements, especially with large flange diameters can lead to the destruction of the membrane.
Der Erfindung liegt die Aufgabe zugrunde, einer solchen Membrandichtung eine erhöhte Nachgiebigkeit zu geben. Dies wird ausgehend von einer Membran-Schweißdichtung der eingangs definierten Art erfindungsgemäß dadurch erreicht, daß zwischen der Membran und den Anschlußringen zur Erhöhung der Nachgiebigkeit ein weiterer im Querschnittsprofil kreisringförmiger Membranteil vorgesehen ist.The invention is based on the object of providing such a membrane seal with increased flexibility admit. This is based on a membrane welding seal of the type defined at the beginning according to the invention achieved that between the membrane and the connecting rings to increase the Resilience a further in the cross-sectional profile circular diaphragm portion is provided.
Die erfindungsgemäße Doppelringmembran weist eine solche Elastizität auf, daß auch bei großen Temperaturunterschieden zwischen den Flanschen die Dichtheit des Hochdruckapparates gewährleistet ist. Der Mehraufwand für die Herstellung der erfindungsgemäßen Membran ist nicht groß, da der zweite zusätzliche Ring die Membran nur um etwa ein Drittel vergrößert und die Bearbeitung ohne nochmaliges Umspannen des Werkstückes erfolgen kann. Wenn die Membran durch Pressen hergestellt wird, sind die Werkzeugkosten nicht viel höher, als für die bekannte Membran.The double ring membrane according to the invention has such an elasticity that even with large temperature differences the tightness of the high-pressure apparatus is guaranteed between the flanges. The additional expense for the production of the invention Diaphragm is not large as the second additional ring only covers the diaphragm by about a third enlarged and the machining can take place without repeated reclamping of the workpiece. if If the membrane is made by pressing, the tooling costs are not much higher than for the known one Membrane.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing.
Bei der gezeigten Flanschverbindung eines Hochdruckapparates sind die beiden Flansche 1, 2 unter Zwischenschaltung einer Membran 10 miteinander verschweißt. Zwischen den Flanschen 1, 2 sind zwei Anschlußringe 4,5 eingespannt, von denen jeder an seiner dem Apparateinnern zugewandten Seite eine Hälfte der im Querschnittsprofil kreisringförmigen auf ihrem inneren Umfang zusammengeschweißten Membran 10 trägt und deren aufeinanderliegende Flächen 6 durch Schrauben 7 der Flansche 1,2 gegeneinandergepreßt werden.In the flange connection of a high pressure apparatus shown, the two flanges 1, 2 are below Interposition of a membrane 10 welded together. Between the flanges 1, 2 are two Connection rings 4.5 clamped, each of which has one on its side facing the inside of the apparatus Half of the circular ring-shaped in cross-sectional profile welded together on their inner circumference Membrane 10 carries and its superposed surfaces 6 by screws 7 of the flanges 1,2 are pressed against each other.
Zur Erhöhung der Nachgiebigkeit der Membran bei besonderen Betriebsverhältnissen ist erfindungsgemäß
zwischen der Membran 10 und den Anschluß-Membran-Schweißdichtung für
Flanschverbindungen an HochdruckapparatenTo increase the flexibility of the membrane under special operating conditions, according to the invention, between the membrane 10 and the connection membrane welding seal for
