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.
