Description

  

  Dispositif de raccordement de conduites    La présente invention     concerne    un     dispositif    de       raccordement    de     conduites        en    ne matière synthéti  que présentant une     certaine        souplesse    notamment le       polytétrafluoréthylène.     



  Suivant     l'invention,    le dispositif de     raccordement     de conduites en matière synthétique présentant une  certaine souplesse, notamment le     polytétrafluoT6thy-          lène,    ces     conduites        étant        terminées    par des     sections     droites à bords     francs,

      est caractérisé en ce     qu'il    com  prend pour chaque     conduite    deux     demi-bagues    intro  duites dans une gorge     pratiquée    à la     périphérie    de la  conduite au     voisinage    de son extrémité et un     ensem-          ble    de     brides    serrant l'une vers l'autre les     bagues.     



  Aux dessins     annexés,    donnés à titre     d'exemples,     une forme     d'exécution    de     l'objet    de     l'invention    et une  variante seront     décrites.     



  La     fig.    1 est une vue en     élévation        latérale,    avant  montage, des éléments constitutifs du dispositif de  raccordement.  



  La     fig.    2     est    la vue en .coupe axiale du     dispositif          urne    fois mis .en place.  



  La     fig.    3 est la     coupe        transversale    correspondante  suivant     III-III    -de la     fig.    2.  



  La     fig.    4 est une vue .analogue à la     fig.    2 d'une       variante.     



  En se reportant à la     fig.    1, on     voit    .en 1 et 2 les  deux conduites     destinées    à être raccordées. Ces     con-          dui,tes    sont par exemple en     polytétrafluoréthylène    et  servent au transport de réactifs chimiques.  



  Les conduites 1 et 2 sont terminées par -des sec  tions droites 3, 4 à bords francs,     bien        parallèles    entre  elles, lorsque les conduites sont placées     coaxialcment.     



  Les conduites présentent à faible     distance    des  sections droites 3 et 4, des gorges     circulaires    5 et 6  dont la profondeur est par exemple la moitié ou     1e     tiers de     l'épaisseur    de la conduite.

      Le dispositif de jonction     comprend    d'autre     part          pour        .chaque    conduite, deux     demi-bagues    métalliques,  par     exemple    en     .acier.    Pour la conduite 1,     les        demi-          bagues    7 sont     simplement        .constituées    par des     demi-          rondelles    .planes.  



  Pour l'autre conduite 2,     les    demi-bagues 8 pré  sentent une     partie        radiale    12, prolongée par un     demi-          manchon    14 dont la longueur est     supérieure    à     la    -dis  tance     comprise    entre la rainure 6 et     lia        section    4 et  inférieure à la distance séparant lies,     gorges    5 et 6  lorsque les conduites sont mises bout à bout.  



       L'épaisseur    des     parties        radiales        des    demi-bagues  précédentes correspond à la     largeur    l'es gorges. 5 et 6.  Le     dispositif    de     raccordement        comprend        enfin     dieux brides en acier 15, 16     décolletées    sur l'une de  leurs faces pour former des     logements    17, 18 capa  bles de recevoir les     demi-bagues    7 et 8     respective-          ment.     



       Les        brides    15,<B>16</B> peuvent être     solidarisées    par  des boulons     traversants    19, pouvant recevoir     l'es     écrous 20.  



  La mise en     place    des éléments     précédaale    est la  suivante  On place les     demi-bagues    7     dans    la     gorge    5 et  on les     coiffe    par la bride 15. On     place        aussi    les ner  vures 12 des     demi-bagues    8 dans     larainure    6 et on  les coiffe par la bride 16.

   On     met    alors les conduites  1 et 2 bout à bout, les     sections        droites    3 et 4 étant  en     contact.    Cette opération est     facilitée    par la col  lerette     formée    par les     demi-manchons    14 qui font       saillie        au,delà    .de la     section    4, compte tenu de la  longueur     prévue    pour ces     .piàces.     



  Cette     ooincid!enoe    étant     iréalisée,    on     met    .en     place     les boutons 19 et on serre fortement     ires        écrous    20.       L'expérience        montre        alors    que la     jonction        ainsi     réalisée est rigoureusement étanche.

   En     particulier,        @et     malgré l'absence de tout joint, il ne se produit pas de      fuites radiales entre les     sections    3 et 4.     Mieux,    on a  constaté que si la charge des     conduites        dépassait    leur  résistance à l'éclatement, ce dernier se produisait       ailleurs        :qu'à    la jonction.  



  En fait, il semble que     -les    bagues 7 et 8 répartis  sent la     poussée    provenant des brides 15, 16 ;     cette     poussée sur les extrémités des conduites étant suffi  sante,     compte    tenu de la     souplesse        résiduelle        de    la       matière    pour     empêcher        tout    passage     radial        entre    les  deux     conduites.     



  Dans la     réalisation    de la     :fig.    4, on     ra        placé    autour  des conduites 1 et 2 des gaines     métalliques        tressées     21, 22 à haute     résistance    à l'extension. Ces gaines  épousent     -la    forme des gorges 5, 6 où     elles    sont     serrées     par les bagues 7, 8.

   On     reinfomce        .ainsi    lia résistance  à l'éclatement des conduites qui     devient    comparable  le long des     conduites    et à     leur    jonction.  



       Les    gorges 5, 6 des     conduites        pourraient        être    rem  placées par des nervures     circulaires,    en saillie rela  tivement à la surface :de la conduite.



  The present invention relates to a device for connecting pipes made of only synthetic material having a certain flexibility, in particular polytetrafluoroethylene.



  According to the invention, the device for connecting pipes made of synthetic material having a certain flexibility, in particular polytetrafluoT6thy- lene, these pipes being terminated by straight sections with blunt edges,

      is characterized in that it comprises for each pipe two half-rings inserted in a groove made at the periphery of the pipe near its end and a set of flanges clamping the rings towards each other .



  In the accompanying drawings, given by way of examples, an embodiment of the object of the invention and a variant will be described.



  Fig. 1 is a side elevational view, before assembly, of the constituent elements of the connection device.



  Fig. 2 is the axial sectional view of the urn device once put in place.



  Fig. 3 is the corresponding cross section along III-III -of FIG. 2.



  Fig. 4 is a view .analogue to FIG. 2 of a variant.



  Referring to fig. 1, we see .en 1 and 2 the two pipes intended to be connected. These conduits are for example made of polytetrafluoroethylene and serve for the transport of chemical reagents.



  The pipes 1 and 2 are terminated by straight sections 3, 4 with blunt edges, very parallel to each other, when the pipes are placed coaxially.



  At a short distance, the pipes have straight sections 3 and 4, circular grooves 5 and 6, the depth of which is for example half or 1e third of the thickness of the pipe.

      The junction device comprises on the other hand, for each pipe, two metal half-rings, for example made of steel. For line 1, the half-rings 7 are simply .constituted by half-flat washers.



  For the other pipe 2, the half-rings 8 have a radial part 12, extended by a half-sleeve 14, the length of which is greater than the distance between the groove 6 and the section 4 and less than the distance separating lees, grooves 5 and 6 when the pipes are placed end to end.



       The thickness of the radial parts of the preceding half-rings corresponds to the width of the grooves. 5 and 6. The connection device finally comprises two steel flanges 15, 16 turned off on one of their faces to form housings 17, 18 capable of receiving the half-rings 7 and 8 respectively.



       The flanges 15, <B> 16 </B> can be secured by through bolts 19, which can receive the nuts 20.



  The installation of the preceding elements is as follows. The half-rings 7 are placed in the groove 5 and they are capped by the flange 15. The ribs 12 of the half-rings 8 are also placed in the groove 6 and they are capped by the flange 16.

   The pipes 1 and 2 are then placed end to end, the straight sections 3 and 4 being in contact. This operation is facilitated by the collar formed by the half-sleeves 14 which protrude beyond .de section 4, given the length provided for these .piàces.



  This ooincid! Enoe being unrealized, the buttons 19 are put in place and the nuts 20 are tightened strongly. Experience then shows that the junction thus produced is strictly sealed.

   In particular, @and despite the absence of any seal, radial leaks do not occur between sections 3 and 4. Better still, it has been observed that if the load of the pipes exceeds their resistance to bursting, the latter will produced elsewhere: than at the junction.



  In fact, it seems that the distributed rings 7 and 8 feel the thrust coming from the flanges 15, 16; this thrust on the ends of the pipes being sufficient, taking into account the residual flexibility of the material to prevent any radial passage between the two pipes.



  In the embodiment of: fig. 4, braided metal sheaths 21, 22 with high resistance to extension are placed around the pipes 1 and 2. These sheaths match the shape of the grooves 5, 6 where they are clamped by the rings 7, 8.

   This reinforces the resistance to bursting of the pipes, which becomes comparable along the pipes and at their junction.



       The grooves 5, 6 of the pipes could be replaced by circular ribs, projecting relative to the surface: of the pipe.
