Description

  

  Raccord pour deux tubes tels que deux tubes à gaz.    La     présente    invention a pour objet un  raccord pour deux tubes tels que deux tubes  à gaz, caractérisé par le fait qu'il     comprend     un manchon dont au moins une des     extré-          mités:

      présente un filetage     destiné    à recevoir  un écrou     .disposé    .de manière à presser sur au  moins un élément     d'étanchéité        monté    sur un  premier     tube,        lorsque    celui-ci est engagé     dans     ladite     extrémité    du manchon, des, moyens  étant ménagés pour assembler l'autre extré  mité de ce manchon au second     tube.     



  Le     dessin    annexé montre, à titre     d'exem-          pl.e,    une forme     d'exécution    du     raccord,    objet  de l'invention.  



  La     fig.    1 en est une vue     longitudinale    en  coupe     partielle,     la     fig.    2 une vue en     plan    d'une     bague          métallique        et     la fi-. 3 une vue de profil die     celle-ci.     



  Le raccord représenté comprend un man  chon cylindrique 16, comportant deux parties  rectilignes,     coaxiales    let 2, de     diamètres.        dif-          férents,        raccordées    par     une        partie    tronco  nique 3;     1a    partie 1, de     plus    petit     diamètre,     possède un filetage 4 destiné à être vissé  sur un     premier    tube à gaz; la partie 2, de  plus grand diamètre, est munie à son extré  mité libre 5 -d'un filetage 6 sur lequel un       écrou    7 est destiné à être vissé;

   à l'intérieur  de cette     partie    2 est engagée une des extré  mités 14 d'un     second    tube à gaz 8.  



  L'écrou 7 comporte     intérieurement    un       épaulement    circulaire 9     destiné    à presser sur  une bague métallique 10 montée sur le    tube 8; cette bague 10 permet de serrer un  anneau d'étanchéité 11 prenant appui, d'autre  part, contre un chanfrein 12 ménagé à l'ex  trémité 5 de la, partie 2 du manchon. La  bague 10 présente une solution de conti  nuité 13 lui permettant de s'ouvrir plus ou  moins selon les irrégularités, de la     surface          extérieure    du     tube    8.

   Ce dernier peut être       immobilisé    dans le sens longitudinal, à l'in  térieur de la partie 2, au moyen d'une vis de  pression 15 que     porte    l'écrou 7.  



  Dans une variante d'exécution, l'écrou 7  peut être muni de     plusieurs        vis    15.  



  La     partie    rectiligne<B>2</B> du     manchon    16 pos  sède une paroi dont:     l'épaisseur    est plus  grande que celle de la paroi des tubes à       assembler,    pour renforcer la     conduite    à  laquelle ils appartiennent au droit du raccord.  



  Le raccord représenté, plus     spécialement     destiné à remplacer une portion de tube pré  sentant une perforation, est.     utilisé    comme  suit:  La partie 2 dû manchon<B>H</B> est engagée  autour du tube 8     ainsi    que l'écrou 7, l'anneau  11 et la bague 10, puis la partie 1 est vissée à  une extrémité     taraudée        correspondante    de  l'autre tube à raccorder (non représenté);  l'écrou 7 est ensuite actionné pour serrer  l'anneau et la bagua susmentionnés et la vis  de pression 15 est vissée pour     immobilioer    le  tube 8 dans le sens longitudinal.  



  Il est prévu dans une variante d'exécution  de     réaliser    un     manchon    16 comprenant une  seule partie     rectiligne    2     po,#.sédant    à chacune      de ses extrémités un filetage 6     destiné    à re  cevoir un écrou 7 ;     :chaque    écrou 7 peut être  muni de vis de pression 15 et     comporter    un       épaulement        circulaire    9 destiné à presser sur  une bague 10 et     un    anneau 11 que porte un  des tubes à     raccorder.  



  Connection for two pipes such as two gas pipes. The present invention relates to a connector for two tubes such as two gas tubes, characterized in that it comprises a sleeve of which at least one of the ends:

      has a thread intended to receive a nut .disposed .de way to press on at least one sealing element mounted on a first tube, when the latter is engaged in said end of the sleeve, means being provided for assembling the other end of this sleeve to the second tube.



  The accompanying drawing shows, by way of example, an embodiment of the connector, object of the invention.



  Fig. 1 is a longitudinal view thereof in partial section, FIG. 2 a plan view of a metal ring and the fi. 3 a side view of the latter.



  The connector shown comprises a cylindrical sleeve 16, comprising two rectilinear parts, coaxial let 2, of diameters. different, connected by a frustoconical part 3; 1a part 1, of smaller diameter, has a thread 4 intended to be screwed onto a first gas tube; part 2, of larger diameter, is provided at its free end 5 - with a thread 6 onto which a nut 7 is intended to be screwed;

   inside this part 2 is engaged one of the ends 14 of a second gas tube 8.



  The nut 7 internally comprises a circular shoulder 9 intended to press on a metal ring 10 mounted on the tube 8; this ring 10 makes it possible to tighten a sealing ring 11 bearing, on the other hand, against a chamfer 12 formed at the end 5 of the, part 2 of the sleeve. The ring 10 has a continuity solution 13 allowing it to open more or less according to the irregularities of the outer surface of the tube 8.

   The latter can be immobilized in the longitudinal direction, inside part 2, by means of a pressure screw 15 carried by nut 7.



  In an alternative embodiment, the nut 7 can be provided with several screws 15.



  The rectilinear part <B> 2 </B> of the sleeve 16 has a wall, the thickness of which is greater than that of the wall of the tubes to be assembled, to reinforce the pipe to which they belong to the right of the connection.



  The connector shown, more especially intended to replace a portion of tube having a perforation, is. used as follows: Part 2 of the <B> H </B> sleeve is engaged around tube 8 together with nut 7, ring 11 and ring 10, then part 1 is screwed to a corresponding threaded end the other tube to be connected (not shown); the nut 7 is then actuated to tighten the aforementioned ring and bagua and the pressure screw 15 is screwed to immobilize the tube 8 in the longitudinal direction.



  In an alternative embodiment, provision is made for a sleeve 16 comprising a single 2 in. Rectilinear portion, #. Attracting at each of its ends a thread 6 intended to receive a nut 7; : each nut 7 can be provided with pressure screw 15 and include a circular shoulder 9 intended to press on a ring 10 and a ring 11 which carries one of the tubes to be connected.
