Description

  

  Überlappende     Blechverbindung.       Die vorliegende Erfindung     betrifft    eine  überlappende Blechverbindung, die derart aus  gebildet ist, dass die Prüfung der Dichtheit  derselben mittelst einer in einem Zwischenraum  zwischen den überlappten Blechen     eingepress-          ten        Druckflüssigkeit    erfolgen kann.

   Sie  besteht darin, dass die Abdichtung des  Prüfzwischenraums einerseits mittelst einer  Schweissnaht und anderseits durch einen  Dichtungsring bewerkstelligt ist, wobei im  Falle schräger     Überlappung    der Bleche der  genannte Dichtungsring zweckmässig so an  geordnet ist, dass er beim     Übereinanderschie-          ben    der Bleche eine     Verpressung    erfährt.  



  Die Zeichnung veranschaulicht mehrere  Ausführungsbeispiele des Erfindungsgegen  standes bei     Rundnahtsehluss;          Fig.        f.    und 2 zeigen zwei Ausführungen  der Verbindung dickwandiger Bleche;       Fig.    3 zeigt die Verbindung dünnwandi  ger, überlappender Bleche.  



  Bei allen Ausführungsformen sind die  Blechenden     9.,    B so ausgebildet, dass im  überlappten Zustande zwischen ihnen ein    Zwischenraum C vorhanden ist, in den nach  Verschweissen der     Endstösse    mittelst einer  Bohrung b eine     Druckflüssigkeit    zur Prüfung  der Dichtheit der Verbindung     eingepresst     werden kann. In den Zwischenräumen C ist  ein Dichtungsring d eingelegt, der bei schrä  ger     Überlappung    der Bleche beim     Übereinan-          derschieben    derselben durch den konischen  Anzug der Blechenden eine     Vorpressung    er  fährt.  



  Nachdem die Schweissnaht i ausgeführt  ist, kann durch die Öffnung bin den Zwi  schenraum C die     Druckflüssigkeit        eingepresst     werden, wobei die Dichtung einerseits durch  den Dichtungsring d, anderseits durch die  Schweissnaht i gebildet wird. Letztere kann  auf diese Weise auf ihre Dichtheit geprüft  werden. Analogerweise wird die Prüfung der  Dichtheit der Schweissnaht     a    unter Benutzung  des gleichen Dichtungsringes d vorgenommen.



  Overlapping sheet metal connection. The present invention relates to an overlapping sheet metal connection which is designed in such a way that the tightness of the same can be checked by means of a pressure fluid pressed into a space between the overlapped sheets.

   It consists in the sealing of the test space on the one hand by means of a weld seam and on the other hand by a sealing ring, whereby in the case of an oblique overlap of the sheets the said sealing ring is expediently arranged in such a way that it experiences a compression when the sheets are pushed over one another.



  The drawing illustrates several exemplary embodiments of the subject matter of the invention in the case of a circular seam; Fig. F. and Fig. 2 show two embodiments of the connection of thick-walled sheets; Fig. 3 shows the connection thin wall ger, overlapping metal sheets.



  In all embodiments, the sheet metal ends 9, B are designed so that in the overlapping state there is an interspace C between them, into which, after the end joints have been welded, a pressure fluid can be pressed by means of a bore b to test the tightness of the connection. A sealing ring d is inserted into the spaces C, which, when the sheets overlap at an angle, when they are pushed over one another, is pre-pressed due to the conical tightening of the sheet ends.



  After the weld seam i has been made, the pressure fluid can be pressed in through the opening in the intermediate space C, the seal being formed on the one hand by the sealing ring d and on the other hand by the weld seam i. The latter can be checked for leaks in this way. In an analogous manner, the tightness of the weld seam a is tested using the same sealing ring d.

Claims (1)

PATENTANSPRUCH: Überlappende Blechverbindung, die derart ausgebildet ist, dass die Prüfung der Dicht- heit derselben mittelst einer in einem Zwi schenraum zwischen den überlappten Blechen eingepressten Druckflüssigkeit erfolgen kann, dadurch gekennzeichnet, dass die Abdichtung des Prüfzwischenraums einerseits mittelst einer Schweissnaht und anderseits durch einen Dich tungsring bewerkstelligt ist. UNTERANSPRUCH: Überlappende Blechverbindung nach Pa tentanspruch, dadurch gekennzeichnet, dass die Überlappung schräg ist und dass der Dichtungsring so angeordnet ist, dass er beim Übereinanderschieben der Bleche eine Vor pressung erfährt. PATENT CLAIM: Overlapping sheet metal connection which is designed in such a way that the tightness of the same can be checked by means of a pressure fluid pressed into an intermediate space between the overlapped sheets, characterized in that the test gap is sealed on the one hand by means of a weld seam and on the other hand by a seal processing ring is accomplished. SUBCLAIM: Overlapping sheet metal connection according to patent claim, characterized in that the overlap is inclined and that the sealing ring is arranged in such a way that it is pre-pressed when the sheets are pushed over one another.
