Description

  

      Einrichtung    zum Abdichten von Flanschen.         Es    ist bereits bekannt, Flanschen statt  durch     Zwischenlegen    von     Dichtungsscheiben     dadurch abzudichten, dass an der Dichtfläche  des einen Flansches     eine    Feder und an der  Dichtfläche des andern Flansches eine ent  sprechende     Nnt    ausgebildet ist. Um dieses  Abdichtungsprinzip "Nut und Feder" auch  auf bestehende     Flanschverbindungen    ausdeh  nen zu können, sind an beiden Flansch  flächen Nuten ausgedreht und ein Ring zwi  schengelegt worden, an dessen Stirnflächen  beiderseits Federn     ausgebildet    sind.  



  Die den Gegenstand vorliegender Erfin  dung bildende     Einrichtung    geht einen  Schritt     weiter,        indem    an Stelle eines Flach  ringes mit Federerhöhungen ein Profilring  verwendet     wird,    dessen Querschnittform der       Form        eines        Rechteckes    mit     abgerundeten     Ecken entspricht.

   Ein solcher Profilring hat  den Vorteil leichterer Massenherstellung     und     den     desi    'besseren     Enliegens    in den Nut  bettungen zufolge Wegfalles der Aussen- und       Innenfedern    und bietet die Möglichkeit einer       innigeren,        abstandsverringernden    Verbin  dung.  



  In der Zeichnung ist die Erfindung bei  spielsweise veranschaulicht, und zwar zeigt:         Fig.    1 den Dichtungsring im Schnitt,       Fig.    2 die     Flanschabdichtung    im Schnitt,       Fig.    3 das Querschnittprofil in grösserem  Massstab.  



  Im Flansch 1 und Gegenflansch 2 sind je  eine Nute 3 ausgebildet. Der     Dichtungsring     4, der z. B. aus Gummi besteht, besitzt die       Quensichnittform        eines        Rechteckes        mit    ab  gerundeten Ecken mit der Besonderheit, dass  die Kurvenübergänge 5 der Ecken als An  lageflächen     ballig    verlaufen.



      Device for sealing flanges. It is already known to seal flanges instead of interposing sealing washers in that a spring is formed on the sealing surface of one flange and a corresponding Nnt is formed on the sealing surface of the other flange. In order to be able to expand this sealing principle "tongue and groove" to existing flange connections, grooves are turned out on both flange surfaces and a ring has been put in between, on the end faces of which springs are formed on both sides.



  The device forming the subject of the present invention goes a step further by using a profile ring in place of a flat ring with spring elevations, the cross-sectional shape of which corresponds to the shape of a rectangle with rounded corners.

   Such a profile ring has the advantage of easier mass production and the better fit in the groove bedding due to the omission of the outer and inner springs and offers the possibility of a more intimate, distance-reducing connec tion.



  In the drawing, the invention is illustrated by way of example, namely: FIG. 1 shows the sealing ring in section, FIG. 2 shows the flange seal in section, FIG. 3 shows the cross-sectional profile on a larger scale.



  A groove 3 is formed in each of the flange 1 and mating flange 2. The sealing ring 4, the z. B. consists of rubber, has the Quensichnittform of a rectangle with rounded corners from with the special feature that the curve transitions 5 of the corners are convex as to contact surfaces.
