Description

  

  Kupplung zum lösbaren     Verbinden    von     Hochdruckrohren       Gegenstand des Hauptpatentes Nr. 435 888 ist eine  Kupplung zum lösbaren Verbinden von runden, glattflä  chigen Hochdruckröhren, die je in vorbestimmtem     Ab-          ,stand    von ihren zu verbindenden     Endstirnflächen    mit  einem Ringwulst versehen sind, gegen welche Ringwülste       bei    geschlossener Kupplung koaxial auf den Röhren  verschiebbare Hülsen von aussen her angedrückt werden,       mindestens,    wenn die Rohrleitung" unter Druck gesetzt  wird.

   Nach dem Hauptpatent ist die Kupplung erfin  dungsgemäss dadurch gekennzeichnet,     dass    die Hülsen  zum Halten einer zwischen ihren Innenflächen und den       Rohr-Aussenflächen    zur Überbrückung der Trennstelle  lose eingesetzten zylindrischen Dichtungshülse ausgebil  det sind, die in     Innen-Nuten    eingelegte O-Ringe aus  gummielastischem Dichtungsmaterial enthält, welche im  Zusammenwirken mit den     Rohr-Aussenflächen    die Ab  dichtung der Rohrverbindung bewirken und dass die  genannten Halte-Hülsen zum gegenseitigen lösbaren Ver  binden ausgebildet     sind.     



  Es wurden im Hauptpatent Ausführungsformen mit  Hülsenteilen beschrieben, die zusammen je eine Um  fangsnut zur Aufnahme eines Schliessringes bilden. Ge  mäss vorliegender Zusatzerfindung ist eine Kupplung  ,dieser Art dadurch gekennzeichnet, dass der Schliessring  seinerseits aus zwei Halbringen besteht, die am Aussen  umfang zusammen eine Nut zur Aufnahme eines Feder  drahtringes bilden, der bestrebt ist, die beiden Halbringe  zum Schliessring zu schliessen, aber deren Rufspreizung  gegen die Federspannung zulässt.  



  Ein     Ausführungsbeispiel    dieser Art ist in der Zeich  nung dargestellt. Es zeigen darin:       Fig.    1 eine Ansicht einer geschlossenen Kupplung       Fig.    2 eine Stirnansicht in Richtung des Pfeiles 11  ,

  von     Fig.    1       Fig.    3 einen     Diametralschnitt    durch eine Kupplungs  hälfte       Fig.    4 eine Seitenansicht der Schliessfeder       Fig.    5 eine Frontansicht der Schliessfeder       Fig.    6 eine Frontansicht der beiden     Schliessringhälf-          ten    ohne Schliessfeder       Fig.    7 einen Teilschnitt durch den kompletten  Schliessring in Wirklage in     vergrössertem    Massstab.    Die beiden zu verbindenden     Hochdruckrohrenden     sind mit 11 bzw. 12 bezeichnet.

   Die Dichtungshülse 40  mit den beiden eingesetzten Dichtungsringen sowie der  Rohrwulst 120 des Rohres 12 sind in     Fig.    3 sichtbar. Die  Haltehülsen, welche dazu bestimmt sind, die Dichtungs  hülse 40 an der Stossstelle der beiden Rohre 11 und 12 zu  deren Überbrückung und Abdichtung zu halten, sind mit  22' bzw. 21' bezeichnet. Sie bilden ineinander steckbare  Klauen 211' bzw. 221', die an ihren freien Enden mit je  einem Kragen 212' bzw. 222' versehen sind. Auf den  Innenseiten gegen die zugehörigen Haltehülsen sind die       Klauenkragen    zur Bildung einer     Ringnutflanke    und auf  der Aussenseite mit einer     Konusanschrägung    versehen.

    In die durch die ausgekehlten Seiten der     Klauenkragen     nach dem Zusammenstecken der Haltehülsen gebildete  Umfangsnut ist ein Schliessring, bestehend aus zwei mit  Hilfe einer Schliessfeder 300 vereinigten Halbringen 301,  302, eingesetzt. Die Schliessfeder 300 ist bestrebt, die  beiden     Schliessring-Halbringe    300, 302 zu einem ge  schlossenen Ring zu vereinigen, lässt aber deren Ruf  spreizung zum Setzen bzw. zum Öffnen der Kupplung  leicht zu. Die Zugkräfte der Haltehülsen werden von den  beiden Halbringen aufgenommen, und die Schliessfeder  300 ist so ausgebildet, dass die Stossstellen der Stahlringe  nicht an die Stossflanken zwischen den     Haltehülsennok-          ken    zu liegen kommen.



  Coupling for detachable connection of high-pressure pipes The subject of the main patent No. 435 888 is a coupling for detachable connection of round, smooth-surface high-pressure pipes, which are provided with an annular bead at a predetermined distance from their end faces to be connected, against which annular beads when closed Coupling coaxially on the tubes displaceable sleeves are pressed from the outside, at least when the pipeline is "put under pressure.

   According to the main patent, the coupling is in accordance with the invention characterized in that the sleeves are designed to hold a cylindrical sealing sleeve loosely inserted between their inner surfaces and the outer pipe surfaces to bridge the separation point, which contains O-rings made of rubber-elastic sealing material inserted in inner grooves which, in cooperation with the pipe outer surfaces, cause the pipe connection to be sealed off and that said retaining sleeves are designed to connect releasably to one another.



  There were described in the main patent embodiments with sleeve parts, which together each form a circumferential groove to receive a locking ring. According to the present additional invention, a coupling of this type is characterized in that the locking ring in turn consists of two half-rings which together form a groove on the outer circumference for receiving a spring wire ring, which strives to close the two half-rings to the locking ring, but their Allow spreading against the spring tension.



  An embodiment of this type is shown in the drawing. They show: FIG. 1 a view of a closed coupling; FIG. 2 an end view in the direction of arrow 11;

  1, 3, a diametrical section through a coupling half, FIG. 4, a side view of the closing spring, FIG. 5, a front view of the closing spring, FIG. 6, a front view of the two closing ring halves without the closing spring, FIG. 7, a partial section through the complete closing ring in the operative position on a larger scale. The two high-pressure pipe ends to be connected are labeled 11 and 12, respectively.

   The sealing sleeve 40 with the two sealing rings used and the tubular bead 120 of the tube 12 can be seen in FIG. 3. The holding sleeves, which are intended to hold the sealing sleeve 40 at the joint between the two tubes 11 and 12 for bridging and sealing them, are denoted by 22 'and 21', respectively. They form claws 211 'and 221' which can be plugged into one another and which are each provided with a collar 212 'and 222' at their free ends. On the inside against the associated holding sleeves, the claw collars are provided to form an annular groove flank and on the outside with a conical bevel.

    A locking ring consisting of two half-rings 301, 302 combined with the aid of a locking spring 300 is inserted into the circumferential groove formed by the fluted sides of the claw collars after the holding sleeves have been plugged together. The closing spring 300 strives to unite the two closing ring half-rings 300, 302 to form a closed ring, but allows their call to spread easily to set or to open the clutch. The tensile forces of the holding sleeves are absorbed by the two half-rings, and the closing spring 300 is designed in such a way that the joints of the steel rings do not come to rest on the joint flanks between the retaining sleeve lugs.
