Description

Im Patent 921 i 2o ist eine lösbare, gegen Wärmedehnung, Druckschwankungen sowie Axial- und Radi:alkräfte unempfindliche Dichtung zwischen zwei zu dichtenden Vorrichäungsteilen, z. B. Deckel und Wandung von Druckgefäßen oder zwischen Rohrverbindungen, beschrieben, wobei eine elastische Membran ,angeordnet ist, .die mit dem .einen zu dichtenden Vorrichtungsteil starr verhunden und an :dem anderen Vorrichtungsteil lösbar und dicht oder mit den :beiden zu dichtenden VörrichtungsteHen 'lösbar und .dicht befestigt isst, und wobei :die lösbaren Befestigungsmittel :deer Membran von den gegenseitigen Befestigungsmitteln der beiden Vorrichtun:gsteile konstruktiv getrennt sind.In patent 921 i 2o is a detachable, against thermal expansion, pressure fluctuations as well as axial and radial forces insensitive seal between two to be sealed Vorrichäungstteile, z. B. Lids and walls of pressure vessels or between pipe connections, described, wherein an elastic membrane is arranged, .die with the .ein To be sealed device part rigidly connected and to: the other device part detachable and tight or with the: two devices to be sealed 'detachable and .tightly fastened, and wherein: the releasable fastening means: the membrane of the mutual fastening means of the two devices: structural parts are separated.

Es wurde nun gefunden, däßdiese Dichtung noch weiter verbessert wird, wenn man die :beiderseitigen Dichtungsunterlagen der Membran mit Hinterdrehungen versieht.It has now been found that this seal is still further improved, if you have the: two-sided sealing pads of the membrane with undercuts provides.

Es isst fernerhin von Vorteil, wenn .man die Membran mit einem korroslonsschütze:nden Futter, beispielsweise aus Chromnickelstahl oder Kupfer, verbindet. Aus :dem Werkstoff des Futters kann auch die Membran selbst bestehen.It is also an advantage if you nd the membrane with a corrosion protector Lining, for example made of chrome-nickel steel or copper, connects. From: the material of the lining can also consist of the membrane itself.

Es hat sich weiter gezeigt, daß die Membran mit dem Rohrende aus einem einzigen Stück bestehen kann, wobei dann die entsprechende Lücke zweckmäßig durch mindestens einen zwei- oder mehrteiligen. Ring ausgefüllt wird.It has also been shown that the membrane with the pipe end from one single piece can exist, in which case the corresponding gap expediently through at least one two-part or multi-part. Ring is filled.

An Hand der Abbildungen sei die Erfindung näher erläutert: Gemäß Abb. I ist das Rohr i am Flansch mit einer Hinterdrehung i i verselien, so daß die Membran 6 beim Anziehen der Schrauben io nachgeben kann. Die Hinterdrehung (Rücksprung) 12 am Flansch 9 erleichtert ein etwa notwendiges Abheben der Membran 6 von ihrer Unterlage beim Nachgeben der Schrauben 5 oder Flansche 7.The invention will be explained in more detail using the figures: According to Fig. I verselien the tube i on the flange with an undercut i i, so that the membrane 6 can give way when tightening the screws. The undercut (return) 12 on the flange 9 facilitates any necessary lifting of the membrane 6 from it Support when giving way to screws 5 or flanges 7.

Gleichzeitig wird hierbei ein etwaiges Durchbiegen der Membran 6 bei unbeabsichtigter Drucksteigerung begrenzt.At the same time, any sagging of the diaphragm 6 is achieved unintentional pressure increase limited.

Gemäß Abb. II ist die Membran 6 unmittelbar aus dem Rohr 13 herausgearbeitet. Die so entstandene Lücke wird zweckmäßig durch zwei passende Halbringe 14 ausgefüllt, die gegebenenfalls mit dem Rohrende 13 verschweißt werden können.According to FIG. II, the membrane 6 is worked directly out of the tube 13. The gap created in this way is expediently filled with two matching half rings 14, which can optionally be welded to the pipe end 13.

Abb. III zeigt ein Ausführungsbeispiel der elastischen Dichtung in Verbindung mit einem vor Korrosion schützenden Futter 15.Fig. III shows an embodiment of the elastic seal in Connection to a lining that protects against corrosion 15.
