Description

  

      Dispositif    de joint rapide pour     tubes    souples en     matière        plastique       La     présente        invention    est relative à un dispositif  de joint rapide pour tubes souples en matière plas  tique, servant d'élément de liaison, lors du montage de  conduites tubulaires volantes.  



  On     connaît    divers systèmes pour la liaison de tubes  en matière plastique, mais     ils    :sont,     toutefois,    d'une  manipulation     compliquée    ou d'un emploi limité.  



  Le     dispositif    de joint rapide qui fait l'objet de  l'invention est caractérisé par le fait qu'il comporte  un élément de jonction     constitué    par un manchon qui  présente, à au moins une de ses extrémités, une     partie          femelle    munie intérieurement d'organes     d'agrippage    auto  matiques et d'un anneau d'étanchéité à     autoserrage.     



  Divers exemples de réalisation du     dispositif    de  joint selon l'invention sont représentés sur les dessins  annexés dans lesquels  La fia. 1 est une vue, en coupe longitudinale, d'une  première forme de réalisation, dans la position où il  se trouve au début de     l'accouplement.     



  La     fig.    2 est une vue, en coupe longitudinale par  tielle, du dispositif de joint de la     fig.    1, dans la posi  tion où il se trouve à la     fin    de     l'accouplement.     



  La     fig.    3 est une vue en coupe longitudinale par  tielle d'un élément intermédiaire pour l'accouplement  de tuyaux souples.  



  La     fig.    4 est une vue en coupe     longitudinale    par  tielle illustrant l'application de l'élément suivant la       fig.    3 à la jonction de deux tubes ou tuyaux souples.  



       Les        fig.    5 à 9 représentent en coupe longitudinale  et vues de front, trois     variantes    d'une troisième     forme     d'exécution de l'invention.  



  La     fia.    1 représente les parties de joint 2 et 6  montées sur les extrémités des deux tubes 1, 1 qui  doivent encore être rapprochées de la     distance    V, afin  que les     cliquets    viennent s'engager sur l'épaulement  K. L'anneau de garniture 3 .est dessiné au début de la  déformation qu'il subit de la part de l'enveloppe tron-    conique f de l'embouchure 6, ladite enveloppe étant  renforcée     superficiellement    à l'aide de     fils    en laine de  verre.

      Sur la     fig.    2, on voit le mode d'action du     joint,     L'anneau de garniture 3 est serré entre l'enveloppe  tronconique f de l'embouchure 6, et le manchon 2,  tandis que les ressorts 5 pressent les     cliquets    4, mon  tés de manière rotative sur 10 dans le     manchon    2,  contre le tube 1 lequel, au moyen de l'épaulement     K     de l'embouchure 6 heurtant sur les becs des cliquets,  se trouve être maintenu mécaniquement en     place    dans  ledit manchon. Pour ouvrir un joint, il est suffisant de  presser sur les extrémités des cliquets qui font saillie  par rapport au manchon 2.  



  Sur la     fig.    3, on a représenté un élément inter  médiaire du joint, qui est constitué par un manchon 7  comportant une partie     mâle    7b et une partie femelle  7a. Cet élément, qui doit être inséré dans le joint  représenté à la     fig.    1, a pour but de pouvoir relier     des     tuyaux souples et des tubes sans une préparation spé  ciale des extrémités de ces derniers.

   La liaison fixe et  définitive d'une extrémité de tube ou de tuyau souple  avec le manchon 7 est réalisée simplement en enfilant  dans le manchon 7a     l'extrémité    la qui, à l'aide de  languettes élastiques 11a faisant saillie vers l'intérieur  d'une douille     métallique    en une ou plusieurs     parties     11, logée à mesure dans le manchon 7a, se trouve être  fixée à cette dernière, tandis que l'étanchéité est assu  rée par le serrage de l'anneau élastique 9 entre l'extré  mité et le manchon. Dans cette figure, l'embouchure  7b est l'équivalent de     l'embouchure    6 de la     fig.    1.  



  Un joint complet avec manchon intermédiaire 7  est représenté en position de montage sur la     fig.    4.  La partie femelle du joint est formée par un manchon  2 du     type    déjà décrit en regard de la     fig.    1, dans lequel  toutefois     l'accouplement    à sa     partie    2a, de l'extrémité  <B>1</B> a du tube de droite, est     effectué    par un système      similaire à celui décrit en regard de la     fig.    3,

       c'est-          à-dire    au moyen d'un anneau     métallique    ondulé 8  incorporé dans la partie 2a et d'un anneau     élastique     d'étanchéité 9. La partie mâle du joint est     constituée     par le manchon intermédiaire 7, relié à ladite     partie     femelle, avec le même système de cliquets 4 et épau  lement K     décrits    en regard de la     fig.    1, et relié à  l'extrémité la du tube de gauche, au moyen d'un  manchon femelle 7a et d'un anneau     métallique    on  dulé 8.  



  Sur la     fig.    5, est représenté, en coupe longitudi  nale, un joint dans lequel le blocage des deux extré  mités de tube dans un élément intermédiaire 7, cons  titué par un manchon en matière plastique, est     réalisé     au moyen d'un ou de plusieurs anneaux métalliques 11  incorporés dans ledit manchon.     Chaque    anneau pré  sente une couronne d'ailettes rigides, obliques et ap  pointées vers le centre du manchon et présentant une  section en forme de ciseaux, dont la     partie    émoussée  est tournée vers l'extérieur.

   L'extrémité pénètre facile  ment dans le manchon en raison de ce que son enve  loppe frotte contre les     parties    émoussées des ailettes,  lesquelles, ensuite, avec leurs pointes, bloquent le tube  en empêchant son dégagement du manchon. D'une       mânière    similaire, la     forme    du siège 12 de l'anneau  d'étanchéité 9 permet le retrait de celui-ci pendant  l'introduction du tube, contre lequel au contraire il  vient se serrer si le tube tendait à se dégager sous  l'action d'une pression interne. La     fig.    6 est une vue  frontale d'un     anneau    11. Le siège conique 12 se ter  mine par une enveloppe cylindrique 12a.  



  La     fig.    7 représente en coupe longitudinale un  manchon selon la     fig.    5, dans lequel toutefois les  anneaux avec ailettes 11 sont     remplacés    par des  douilles métalliques dentées 11a qui mordent dans  l'enveloppe extérieure d'un tube élastique 1.  



  La     fig.    8 montre une variante d'exécution du man  chon selon la     fig.    5. La douille dentée est formée de  segments     llb,    dont le dos prend appui contre l'enve  loppe conique de la cavité du manchon 7, lesdits seg  ments présentant vers l'anneau 9 une cavité consti  tuant le siège annulaire 12 dudit anneau.

   Aussitôt que  le tube a été enfilé dans le manchon, il ne peut plus en  sortir puisque, la denture interne des     segments    1 lb  étant engagée dans l'enveloppe du tube, une traction  exercée sur ce tube forcerait     davantage    sur lui les seg  ments qui, de leur côté, prennent appui extérieurement  sur un siège conique de diamètre décroissant dans le  sens de la traction et qui présente une zone dentée 13  laquelle, quoique s'engageant avec les     segments    11b  par l'intermédiaire de l'arête 14 de ces derniers, per  met au siège annulaire 12 de serrer l'anneau d'étan  chéité.

   Par suite,     ce    système de joint est particulière  ment approprié pour des     grands        tubes    et     tuyaux     souples en matière plastique d'un     fort    diamètre.



      The present invention relates to a rapid joint device for flexible plastic tubes, serving as a connecting element, during the assembly of flying tubular conduits.



  Various systems are known for bonding plastic tubes, but they are, however, complicated to handle or of limited use.



  The rapid joint device which is the subject of the invention is characterized in that it comprises a junction element consisting of a sleeve which has, at at least one of its ends, a female part provided internally with members. automatic grippers and a self-tightening sealing ring.



  Various embodiments of the sealing device according to the invention are shown in the accompanying drawings in which La fia. 1 is a view, in longitudinal section, of a first embodiment, in the position in which it is at the start of the coupling.



  Fig. 2 is a view, in partial longitudinal section, of the seal device of FIG. 1, in the position where it is at the end of the coupling.



  Fig. 3 is a view in partial longitudinal section of an intermediate element for the coupling of flexible pipes.



  Fig. 4 is a partial longitudinal sectional view illustrating the application of the element according to FIG. 3 at the junction of two tubes or flexible pipes.



       Figs. 5 to 9 show in longitudinal section and front views, three variants of a third embodiment of the invention.



  The fia. 1 shows the joint parts 2 and 6 mounted on the ends of the two tubes 1, 1 which must still be brought closer to the distance V, so that the pawls come to engage on the shoulder K. The packing ring 3. is drawn at the start of the deformation which it undergoes by the truncated conical casing f of the mouth 6, said casing being reinforced on the surface with the aid of glass wool threads.

      In fig. 2, we see the mode of action of the seal, The packing ring 3 is clamped between the frustoconical casing f of the mouth 6, and the sleeve 2, while the springs 5 press the pawls 4, my tees rotatably on 10 in the sleeve 2, against the tube 1 which, by means of the shoulder K of the mouth 6 striking the jaws of the pawls, is mechanically held in place in said sleeve. To open a seal, it is sufficient to press on the ends of the pawls which protrude from the sleeve 2.



  In fig. 3, there is shown an intermediate element of the seal, which is constituted by a sleeve 7 comprising a male part 7b and a female part 7a. This element, which must be inserted into the seal shown in fig. 1, aims to be able to connect flexible pipes and tubes without special preparation of the ends of the latter.

   The fixed and definitive connection of one end of a tube or flexible pipe with the sleeve 7 is achieved simply by threading the end 1a into the sleeve 7a which, by means of elastic tabs 11a projecting inwardly of a metal sleeve in one or more parts 11, housed in the sleeve 7a, is fixed to the latter, while the seal is ensured by the tightening of the elastic ring 9 between the end and the muff. In this figure, the mouthpiece 7b is the equivalent of the mouthpiece 6 of FIG. 1.



  A complete seal with intermediate sleeve 7 is shown in the mounting position in FIG. 4. The female part of the seal is formed by a sleeve 2 of the type already described with reference to FIG. 1, in which however the coupling to its part 2a, of the end <B> 1 </B> a of the right-hand tube, is effected by a system similar to that described with reference to FIG. 3,

       that is to say by means of a corrugated metal ring 8 incorporated in part 2a and of an elastic sealing ring 9. The male part of the seal is formed by the intermediate sleeve 7, connected to said female part , with the same system of pawls 4 and shoulder K described with reference to FIG. 1, and connected to the end of the left tube, by means of a female sleeve 7a and a metal ring 8.



  In fig. 5, is shown, in longitudinal section, a seal in which the locking of the two tube ends in an intermediate element 7, consisting of a plastic sleeve, is achieved by means of one or more metal rings 11 incorporated in said sleeve. Each ring has a crown of rigid, oblique and ap fins pointed towards the center of the sleeve and having a scissor-shaped section, the blunt part of which faces outwards.

   The end easily penetrates into the sleeve due to its casing rubbing against the blunt portions of the fins, which then with their tips block the tube preventing its release from the sleeve. With a similar hinge, the shape of the seat 12 of the sealing ring 9 allows the latter to be withdrawn during the introduction of the tube, against which, on the contrary, it comes to tighten if the tube tends to come free under the tube. action of internal pressure. Fig. 6 is a front view of a ring 11. The conical seat 12 ends with a cylindrical casing 12a.



  Fig. 7 shows in longitudinal section a sleeve according to FIG. 5, in which however the rings with fins 11 are replaced by toothed metal bushes 11a which bite into the outer casing of an elastic tube 1.



  Fig. 8 shows an alternative embodiment of the man chon according to FIG. 5. The toothed bush is formed of segments 11b, the back of which bears against the conical casing of the cavity of the sleeve 7, said segments having towards the ring 9 a cavity constituting the annular seat 12 of said ring.

   As soon as the tube has been threaded into the sleeve, it can no longer come out since, the internal toothing of the segments 1 lb being engaged in the casing of the tube, a traction exerted on this tube would force the segments which, for their part, bear outwardly on a conical seat of decreasing diameter in the direction of traction and which has a toothed zone 13 which, although it engages with the segments 11b via the ridge 14 of the latter, allows the annular seat 12 to tighten the sealing ring.

   This joint system is therefore particularly suitable for large tubes and flexible plastic pipes with a large diameter.
