Description

  

  Dispositif pour raccorder rapidement deux tronçons d'une conduite de     fluide     sous pression.    La présente invention a pour objet un  dispositif pour raccorder rapidement deux  tronçons d'une conduite de fluide sous pres  sion qui est caractérisé en ce qu'il comporte  une partie à raccorder constituant un élément  femelle à l'intérieur duquel est disposé un  organe d'étanchéité en matière souple, qui  présente un passage dans lequel on enfile  l'extrémité d'un élément mâle que constitue  l'autre partie à raccorder, cet organe étant  disposé de façon que sous l'action de la pres  sion du fluide se trouvant dans la conduite  à raccorder il soit serré autour de cet élé  ment mâle, ce qui assure l'étanchéité entre  les parties raccordées.

   Des moyens de ver  rouillage peuvent être prévus, retenant auto  matiquement les deux parties raccordées en  position de coopération lorsqu'on les y a  amenées, et permettant de libérer instanta  nément ces parties lorsqu'on le désire.  



  La figure unique du dessin annexé repré  sente, à titre d'exemple, une forme d'exécu  tion du     dispositif    faisant l'objet de l'invention.    Ce dispositif comporte deux parties dont  l'une constitue un élément femelle 1, à l'in  térieur duquel est disposé un organe d'étan  chéité 2 en matière souple telle que du  caoutchouc, par exemple, qui présente un  passage axial 3 dans lequel on enfile l'extré  mité 4 d'un élément mâle 5 appartenant à  l'autre partie à raccorder. L'intérieur de  l'élément 1     communique    avec un canal 6 de  fluide sous pression. De même, l'élément 5  est traversé par un canal 7 pour ce fluide  sous pression.

   L'extrémité 4 de l'élément 5  est lisse et s'engage soit à     frottement,    soit  avec un léger jeu dans le passage 3 de l'or  gane 2. Lorsque les parties du dispositif se  trouvent dans la     position    représentée sur le  dessin, la pression régnant dans l'intérieur  de l'élément 1 agit sur la partie 9 de l'or  gane d'étanchéité 2 en la serrant autour de  l'élément 4 avec une force d'autant plus  grande que cette pression est plus élevée par  rapport à la pression extérieure. L'étanchéité  entre les parties raccordées est ainsi assurée.

        L'étanchéité entre l'organe 2 et l'élément  1 est obtenue par serrage de la partie 10  de cet organe 2 contre un épaulement 11 de  l'élément 1, grâce à un bouchon fileté 12  agissant sur cette partie 10 par l'intermé  diaire d'une rondelle métallique 13 présen  tant une bride 14 de forme annulaire,     engagée     dans un logement 15 de forme correspondante  de l'organe 2.  



  S'il y a une fuite entre l'élément 4 et  l'organe d'étanchéité 12, le fluide passe en  3 et, de là, peut gagner l'extérieur. Toute  fois, du fait du laminage que subit le fluide  sous pression lors de son passage en 3, il  se produit une perte de charge, en sorte  que la pression est moins grande à l'extré  mité de droite du passage 3 qu'en 8. Par  conséquent, la force agissant sur la partie 9  est plus grande que celle agissant     radiale-          ment    sur l'organe 2 dans le passage 3.

   En  conséquence, l'espace entre l'organe d'étan  chéité 2 et l'élément 4 diminue, ce qui aug  mente la perte de charge et augmente la       différence    de pression, jusqu'au moment où  cet organe d'étanchéité est     énergiquement     serré autour de l'élément 4.  



  Une poussée axiale s'exerce sur l'élément  mâle, tendant à le séparer de l'autre élément  malgré le serrage dont il vient     d'être    ques  tion. En vue de retenir automatiquement ces  deux éléments en position de     coopération     lorsqu'on les y a amenés, des moyens de  verrouillage sont prévus. Ces moyens com  prennent un loquet 16 pivotant sur la pièce 5  et venant en prise avec le bouchon fileté 12,  comme représenté, lorsqu'on amène l'élément  4 dans la position indiquée sur le dessin.  



  Un ressort non représenté tend constam  ment à écarter ce loquet 16 de la pièce 5.    Une simple pression du doigt sur ce loquet  16 permet de le dégager du bouchon 12 et  de libérer par conséquent instantanément les  deux éléments 1 et 4. Ces moyens de ver  rouillage sont donc indépendants des moyens       assurant    l'étanchéité du dispositif de raccord.  On pourrait utiliser d'autres moyens de ver  rouillage que ceux décrits.  



  Il est clair que l'organe d'étanchéité 2  peut être très souple, même pour de fortes  pressions.



  Device for quickly connecting two sections of a pressurized fluid line. The present invention relates to a device for quickly connecting two sections of a pressurized fluid pipe which is characterized in that it comprises a part to be connected constituting a female element inside which is disposed a member of seal in flexible material, which has a passage in which the end of a male element which constitutes the other part to be connected is threaded, this element being arranged so that under the action of the pressure of the fluid in the pipe to be connected it is tightened around this male element, which ensures the seal between the connected parts.

   Locking means can be provided, automatically retaining the two connected parts in the cooperative position when they are brought there, and making it possible to instantly release these parts when desired.



  The single figure of the appended drawing represents, by way of example, one embodiment of the device forming the subject of the invention. This device comprises two parts, one of which constitutes a female element 1, inside which is disposed a sealing member 2 made of flexible material such as rubber, for example, which has an axial passage 3 in which it is threads the end 4 of a male element 5 belonging to the other part to be connected. The interior of the element 1 communicates with a channel 6 of pressurized fluid. Likewise, the element 5 is crossed by a channel 7 for this pressurized fluid.

   The end 4 of the element 5 is smooth and engages either by friction or with a slight play in the passage 3 of the organ 2. When the parts of the device are in the position shown in the drawing, the pressure prevailing in the interior of the element 1 acts on the part 9 of the sealing member 2 by tightening it around the element 4 with a force all the greater as this pressure is higher by relative to the external pressure. The seal between the connected parts is thus ensured.

        The tightness between the member 2 and the element 1 is obtained by clamping the part 10 of this member 2 against a shoulder 11 of the element 1, thanks to a threaded plug 12 acting on this part 10 through the intermediary diary of a metal washer 13 having a flange 14 of annular shape, engaged in a housing 15 of corresponding shape of the member 2.



  If there is a leak between the element 4 and the seal member 12, the fluid passes through 3 and, from there, can reach the outside. However, due to the rolling that the pressurized fluid undergoes during its passage through 3, a pressure drop occurs, so that the pressure is less at the right end of passage 3 than in 8 Consequently, the force acting on the part 9 is greater than that acting radially on the member 2 in the passage 3.

   Consequently, the space between the sealing member 2 and the element 4 decreases, which increases the pressure drop and increases the pressure difference, until this sealing member is energetically tightened. around element 4.



  An axial thrust is exerted on the male element, tending to separate it from the other element despite the tightening which has just been mentioned. In order to automatically retain these two elements in the cooperative position when they are brought there, locking means are provided. These means com take a latch 16 pivoting on the part 5 and engaging with the threaded plug 12, as shown, when the element 4 is brought into the position shown in the drawing.



  A spring, not shown, constantly tends to move this latch 16 away from part 5. A simple pressure of the finger on this latch 16 allows it to be released from the plug 12 and consequently to instantly release the two elements 1 and 4. These locking means rusting are therefore independent of the means ensuring the sealing of the connecting device. One could use other means of rust worm than those described.



  It is clear that the sealing member 2 can be very flexible, even for high pressures.
