Description

RACCORD POUR ASSEMBLAGE DE TUBES BOUT A BOUTCONNECTION FOR END-TO-END TUBE ASSEMBLY

DESCRIPTIONDESCRIPTION

Cette invention a trait à un raccord pour l'assemblage de deux tubes mis bout à bout. On connaît des raccords pour tubes vissés et soudés, qui présentent en général les désavantages d'être compliqués à monter, d'être détruits s'ils doivent être 10 démontés ou de pouvoir causer des déformations ou d'autres dommages aux bouts des tubes qu'ils joignent.  This invention relates to a connector for joining two tubes placed end to end. Fittings for screwed and welded tubes are known, which generally have the disadvantages of being complicated to assemble, of being destroyed if they have to be dismantled or of being able to cause deformations or other damage to the ends of the tubes which 'they join.

Le raccord de l'invention est dépourvu de ces désavantages: son montage est aisé et rapide, il 15 est parfaitement démontable et n'affecte pas les tubes quoiqu'il soit efficace pour les centrer et garantir l'étanchéité du raccordement. Il peut être employé avec des tubes de tous matériaux.  The connector of the invention does not have these disadvantages: it is easy and quick to assemble, it is perfectly removable and does not affect the tubes, although it is effective in centering them and guaranteeing the tightness of the connection. It can be used with tubes of all materials.

Il comprend un manchon entourant des bouts 20 des tubes avec un jeu, deux brides placées devant deux extrémités opposées du manchon, des tirants s'étendant entre les brides et autour du manchon, et des joints d'étanchéité logés dans des gorges dont une face latérale appartient au manchon et une face latérale 25 opposée appartient aux brides, les joints ayant une largeur inférieure à une largeur des gorges à un état o les brides touchent le manchon; ou encore un manchon entourant des bouts des tubes avec un jeu, deux brides placées devant deux extrémités opposées du 30 manchon, des bagues placées autour des tubes et entre le manchon et les brides, des tirants s'étendant entre le manchon et les brides, des tirants s'étendant entre les brides et autour du manchon, et des joints d'étanchéité logés dans des gorges dont une face latérale appartient au manchon et une face latérale 5 opposée appartient aux bagues, ou dont une face latérale appartient aux bagues et une face latérale opposée appartient aux brides, les joints ayant une largeur inférieure à une largeur des gorges à un état o les bagues touchent le manchon et les brides.  It comprises a sleeve surrounding the ends 20 of the tubes with a clearance, two flanges placed in front of two opposite ends of the sleeve, tie rods extending between the flanges and around the sleeve, and seals housed in grooves, one face of which lateral belongs to the sleeve and an opposite lateral face belongs to the flanges, the joints having a width less than a width of the grooves in a state where the flanges touch the sleeve; or a sleeve surrounding the ends of the tubes with a clearance, two flanges placed in front of two opposite ends of the sleeve, rings placed around the tubes and between the sleeve and the flanges, tie rods extending between the sleeve and the flanges, tie rods extending between the flanges and around the sleeve, and seals housed in grooves one side face of which belongs to the sleeve and an opposite side face 5 belongs to the rings, or one side face of which belongs to the rings and one opposite side face belongs to the flanges, the seals having a width less than a width of the grooves in a state where the rings touch the sleeve and the flanges.

Ses caractères et avantages apparaîtront mieux au commentaire des figures suivantes: - la figure 1 illustre une réalisation simple du raccord, et la figure 2 une réalisation plus complexe.  Its characteristics and advantages will appear better on commenting on the following figures: - Figure 1 illustrates a simple embodiment of the connector, and Figure 2 a more complex embodiment.

La description porte d'abord sur la figure  The description first relates to the figure

1. Un manchon 1 est enfilé sur les bouts de deux tubes 2 et 3 à abouter. Son diamètre est un peu supérieur au 20 leur. Il est flanqué de deux brides 4 qui ont aussi été enfilées sur les tubes 2 et 3. Des tirants 5 s'étendent d'une des brides 4 à l'autre en entourant le manchon 1.  1. A sleeve 1 is threaded on the ends of two tubes 2 and 3 to butt. Its diameter is slightly greater than 20 their. It is flanked by two flanges 4 which have also been threaded onto the tubes 2 and 3. Rods 5 extend from one of the flanges 4 to the other, surrounding the sleeve 1.

Ils ont des bouts filetés traversant des perçages des brides 4; des écrous 6 sont engagés sur les bouts 25 filetés et, quand on les visse, ils approchent les brides 4 l'une de l'autre.  They have threaded ends passing through the holes of the flanges 4; nuts 6 are engaged on the threaded ends 25 and, when they are screwed, they approach the flanges 4 one from the other.

Des joints 7 d'étanchéité complètent le dispositif du raccord. Il ont une section torique à 30 l'état libre et sont logés dans des gorges 8 réparties entre le manchon 1 et les brides 4, ce qui signifie B 14311 JCI qu'une des faces latérales de la gorge 8 est portée par le manchon 1 et l'autre par une des brides 4. Cet agencement est présent aux deux bouts du manchon 1.  Seals 7 complete the fitting device. They have a toric section in the free state and are housed in grooves 8 distributed between the sleeve 1 and the flanges 4, which means that one of the lateral faces of the groove 8 is carried by the sleeve 1 and the other by one of the flanges 4. This arrangement is present at the two ends of the sleeve 1.

Ici, les gorges sont entièrement creusées dans le 5 manchon 1 et les brides 4 ont une face dirigée vers le manchon 1 qui est plane. Les joints 7 ont une largeur supérieure à celle des gorges 8. Quand le vissage des écrous 6 est fini, les brides 4 touchent le manchon 1 et les joints 7, comprimés, sortent par élasticité des 10 gorges 8 en se déformant en direction radiale vers l'intérieur. Ils en viennent à s'appuyer sur les tubes 2 et 3 avec une force suffisant à s'opposer à leur arrachage du raccord. Une étanchéité est aussi créée.  Here, the grooves are entirely hollowed out in the sleeve 1 and the flanges 4 have a face directed towards the sleeve 1 which is planar. The seals 7 have a width greater than that of the grooves 8. When the screwing of the nuts 6 is finished, the flanges 4 touch the sleeve 1 and the seals 7, compressed, come out by elasticity of the 10 grooves 8, deforming in the radial direction towards inside. They come to bear on the tubes 2 and 3 with sufficient force to oppose their tearing of the connector. A seal is also created.

Le centrage des tubes 2 et 3 est maintenu avec une 15 justesse suffisante sans contact direct entre eux, mais une certaine souplesse du raccordement subsiste. Quand le raccord est démonté, les joints 7 reprennent leur forme d'origine, se dilatent hors de contact des tubes 2 et 3.  The centering of the tubes 2 and 3 is maintained with sufficient accuracy without direct contact between them, but a certain flexibility of the connection remains. When the fitting is dismantled, the seals 7 resume their original shape, expand out of contact with the tubes 2 and 3.

La réalisation de la figure 2 diffère de la précédente par l'addition de deux bagues 12 entre le manchon 1 et les brides 4. Les bagues 12 portent aussi des joints 13 d'étanchéité toriques. Les joints 7 déjà 25 rencontrés sont ici comprimés entre le manchon 1 et les bagues 12, tandis que les joints 13 sont comprimés entre l'autre côté des bagues 12 et les brides 4. Les tirants 5 réalisent l'empilement avec contact du manchon 1, des bagues 12 et des brides 4, et la 30 pression latérale repousse encore les joints, ici 7 et B 14311 JCI 13, radialement vers l'intérieur jusqu'à enserrer les tubes 2 et 3.  The embodiment of FIG. 2 differs from the previous one by the addition of two rings 12 between the sleeve 1 and the flanges 4. The rings 12 also carry O-rings 13. The seals 7 already encountered are here compressed between the sleeve 1 and the rings 12, while the seals 13 are compressed between the other side of the rings 12 and the flanges 4. The tie rods 5 carry out the stacking with contact of the sleeve 1 , rings 12 and flanges 4, and the lateral pressure further pushes the seals, here 7 and B 14311 JCI 13, radially inwards until the tubes 2 and 3 are gripped.

Le serrage est ici plus puissant puisqu'il est fait par une paire de joints pour chacun des tubes. 5 Comme les joints 7, les joints 13 sont logés dans des gorges 14 réparties sur deux pièces adjacentes de l'empilement serré par les tirants 5: une de leurs faces latérales appartient à une bride 4, l'autre à une bague 12. D'une façon générale, les joints 7 et 13 ont 10 les mêmes propriétés et la même fonction. Il est manifeste que l'agencement de la figure 2, tel qu'il a été décrit jusqu'ici, résulte de l'ajout des bagues 12 à celui de la figure 1. On a cependant aussi représenté des canaux 15 et 16 pour contrôler l'étanchéité, qui 15 traversent les bagues 12 pour les uns et aboutissent entre les joints 7 et 13, et qui traversent le manchon 1 en biais pour les autres et aboutissent devant les bagues 12. Les uns et les autres donnent sur des rainures 17 et 18 circulaires autour des tubes 2 et 3, 20 ou autour des bagues 12. Si un des joints 7 séparant les canaux de la jonction des tubes défaut, du liquide ou du gaz fuyant d'entre les tubes 2 et 3 le traverse et s'écoule dans les rainures circulaires 17 et 18 puis les canaux 15 et 16 o il est remarqué à un contrôle. 25 Il est encore retenu par les joints 13 et des derniers joints 19 entourant les joints 7 et comprimés entre les périphéries du manchon 1 et des bagues 12. Des bouchons obturent les canaux 15 et 16 entretemps.  The clamping is more powerful here since it is made by a pair of seals for each of the tubes. 5 Like the seals 7, the seals 13 are housed in grooves 14 distributed over two adjacent parts of the stack tightened by the tie rods 5: one of their lateral faces belongs to a flange 4, the other to a ring 12. D generally speaking, the seals 7 and 13 have the same properties and the same function. It is obvious that the arrangement of FIG. 2, as described so far, results from the addition of the rings 12 to that of FIG. 1. However, channels 15 and 16 have also been shown to control the seal, which 15 pass through the rings 12 for one and end between the seals 7 and 13, and which pass through the sleeve 1 at an angle for the others and end up in front of the rings 12. Each gives onto grooves 17 and 18 circulars around the tubes 2 and 3, 20 or around the rings 12. If one of the seals 7 separating the channels from the junction of the fault tubes, liquid or gas leaking from between the tubes 2 and 3 passes through it and s 'flows into the circular grooves 17 and 18 then the channels 15 and 16 where it is noticed at a check. It is still retained by the seals 13 and of the last seals 19 surrounding the seals 7 and compressed between the peripheries of the sleeve 1 and of the rings 12. Plugs close the channels 15 and 16 in the meantime.
