Description
Anlage 2 : Sicherheitsflansch Die Frfindung bezieht sich auf flanschverbindungen, wie sie allgemein in der Technik verwendet werden.Appendix 2: Safety flange The invention relates to flange connections, as they are commonly used in technology.
Die Praxis zeigt, daß die Dichtheit einer Flanschverbindung ein besonderes Problem ist - speziell beisehr giftigen gefährlichen oder radio-aktiven Medien - weil eine Undichtheit im Petriebszustand nicht mehr behoben werden kann.Practice shows that the tightness of a flange connection is a special one The problem is - especially with very toxic, dangerous or radioactive media - because a leak can no longer be remedied in the operating state.
Da also im Getrieb jederzeit und unkontrolliert Undichtigeisen auftreten können , wird die Flanschverbindung bei problematischen Medien zu einem erhöhten Sicherlieitsrisbco.Since leaks occur in the transmission at any time and in an uncontrolled manner the flange connection increases with problematic media Safelyrisbco.
Demgegenüber zeigt die Erfindung einen Weg wie eine Flanschverbindung sicher und tontrollierbar gestaltet werden kann.In contrast, the invention shows a way as a flange connection can be designed safely and controllably.
Durch die Verwendung von mehreren Dichtungen gelingt es Zwischenräume abzugrenzen , die entweder durch Bruckmessung oder andere physikalische oder chemische MeXmethaden überwacht werden können. Ein Austritt des Mediums. kann auch derart verhindert werden ,, daX man in dem Zwischenraum einen Ueberdruck erzeugt , ferner ist eine geziehlte Ableitung von Leckagen möglich. Eine Prüfung der Flanschverbindung während des Retriebs wirddurch Herstellung eines PrüS'drucks im Zwischenraum möglich.The use of several seals creates gaps delimit that either by bridge measurement or other physical or chemical MeXmethaden can be monitored. An exit of the medium. can also be like that prevented, that an overpressure is generated in the space, furthermore a targeted drainage of leaks is possible. A test of the flange connection during operation it is possible to produce a test pressure in the space.
Anhand der Zeichnung solldie Erfindung näher erläutert werden. Die Figuren zeigen ein vereinfachtes schematisches Ausführungsbeispiel der Erfindung.The invention is to be explained in more detail with the aid of the drawing. the Figures show a simplified schematic embodiment of the invention.
Die abgebildete Figur 1 zeigt eine Sicherhe itsflanschverb indung 1,2 mit Doppeldichtungen 5,6, die als Flachdichtungen ausgefuhrt sind. Es können jedoch auch andere Dichtungs-und Flanschformen gewahlt werden, ferner sind grundsatzlich auch drei oder mehr Dichtungen für eine Flanschverbindung mög 1 ich.The depicted Figure 1 shows a safety flange connection 1.2 with double seals 5.6, which are designed as flat seals. It can However, other seal and flange shapes can also be selected, and are also fundamental three or more seals for a flange connection are also possible.
Figur 2 bis 4 zeigen verschiedene möglichkeiten der Dichtungsanordnung. Die Bohrungen 3 und 4 führen zu dem Zwischenraum.Figures 2 to 4 show different possibilities of the sealing arrangement. The holes 3 and 4 lead to the space.
Die an die Bohrungen anzuschließenden Meßgeräte oder Ableitungen ermöglichen es, die Dichtheit der Flanschver -bindung exakt zu jiberwachen , oder anfallende Leckagen auf zufangen.The measuring devices or leads to be connected to the bores allow it is necessary to precisely monitor the tightness of the flange connection, or any incurred Catching leaks.
