Description
La présente invention a pour objet un dispositif de raccordement d'un écrou tournant a l'extrémité d'un tuyau du type onduleux. Ce dispositif est destiné a permettre-, dans les tuyauteries comprenant au moins un tuyau du type onduleux, la connexion de ce tuyau avec un embout fileté appartenant à un autre élément de tuyaute rie, en assurant non seulement l'assemblage mécanique mais aussi l'étanchéité. The present invention relates to a device for connecting a rotating nut at the end of a pipe of the wavy type. This device is intended to allow-, in piping comprising at least one pipe of the wavy type, the connection of this pipe with a threaded end belonging to another pipe element, ensuring not only the mechanical assembly but also the sealing.
Plus particulièrement, l'invention vise la réalisation d'un dispositif de ce genre composé de pie ces simples et courantes, et permettant un montage rapide sur le lieu d'utilisation. More particularly, the invention aims to produce a device of this kind made up of these simple and common pieces, and allowing rapid assembly at the place of use.
A cet effet, le dispositif selon l'invention, pour le raccordement d'un écrou tournant à l'extrémité d'un tuyau de type onduleux,comprend d'une part, à l'extrEmi- té du tuyau, au moins une première onde écrasée et une gorge formée entre deux ondes et apte à recevoir un moyen d'arrêt, et d'autre part, sur l'écrou tournant, une partie alésée apte à recevoir un joint d'étanchéité annulaire ainsi que l'extrémité préalablement formée du tuyau onduleux, les ondes écrasées de cette extrémité étant insérées entre le joint et le moyen d'arrêt. To this end, the device according to the invention, for connecting a rotating nut to the end of a wavy type pipe, comprises on the one hand, at the end of the pipe, at least one first crushed wave and a groove formed between two waves and capable of receiving a stop means, and on the other hand, on the rotating nut, a bored part capable of receiving an annular seal as well as the previously formed end of the corrugated pipe, the crushed waves from this end being inserted between the joint and the stop means.
Suivant un premier mode de réalisation de ce dispositif de raccordement, le moyen d'arrêt est constitué par un organe tels que circlips ou jonc plat, engagé dans la gorge faisant suite à l'onde ou aux ondes écrasées de l'extrémité du tuyau,tandis que la partie alésée de l'écrou tournant comporte une gorge annulaire intérieure apte à recevoir 19 organe tel que circlips ou jonc plat
Suivant un second mode de réalisation, le moyen d'arrd1;; est constitué par une extrémité de 19écrou tour nan# lui#meme, repoussée ou sertie dans la gorge faisant suite à l'onde ou aux ondes écrasées de l'extrémité du tuyau. Cette autre possibilité permet d'utiliser un écrou de forme plus simple,et d'éliminer un organe(circlips ou elle i elle conduit aussi à un assemblage indémontable, m#ie exige un outillage spécial pour effectuer le monta ge.According to a first embodiment of this connection device, the stop means consists of a member such as a circlip or flat rod, engaged in the groove following the wave or waves crushed from the end of the pipe, while the reamed part of the rotating nut has an internal annular groove capable of receiving 19 members such as a circlip or a flat rod
According to a second embodiment, the stop means ;; is formed by an end of the turn nut # nan # itself #, pushed back or crimped in the groove following the wave or crushed waves from the end of the pipe. This other possibility makes it possible to use a nut of simpler shape, and to eliminate an organ (circlips or it i it also leads to a non-removable assembly, m # ie requires special tools to perform the assembly.
Dans tous les cas, il est à noter que le serrage de l'écrou sur l'embout fileté complémentaire, lors du montage de la tuyauterie, provoque la compression du joint par ledit embout fileté; le joint est alors plaqué contre la ou les premières ondes aplaties,maintenues par le moyen d'arrêt (selon le cas :circlips, jonc,partie repoussée ou sertie), ce qui assure l'étanchéité. In all cases, it should be noted that the tightening of the nut on the complementary threaded end piece, during assembly of the piping, causes the seal to be compressed by said threaded end piece; the seal is then pressed against the first flattened wave or waves, held by the stop means (as the case may be: circlip, ring, pushed back or crimped part), which ensures sealing.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, quelques formes de réalisation de ce dispositif- de raccordement:

Comme le montrent les figures 1 et 2, que l'on consi dèrera en premier lieu, le dispositif selon l'invention concerne le raccordement de l'extrémité d'un tuyaux onduleux 1 à un écrou 2, cet écrou devant pouvoir tourner autour de l'axe 3 pour être vissé sur un embout fileté,non représenté. As shown in Figures 1 and 2, which we will consider in the first place, the device according to the invention relates to the connection of the end of a corrugated pipe 1 to a nut 2, this nut having to be able to rotate around axis 3 to be screwed onto a threaded end piece, not shown.
Le tuyau 1 reçoit, dans sa gorge 4 qui suit la pre mière ou la deuxième onde à partir de son extrémité,un circlips 5. The pipe 1 receives, in its groove 4 which follows the first or the second wave from its end, a circlip 5.
L'écrou tournant 2 comporte une partie alésée 6 se raccordant au taraudage 7 par un épaulement 8; une gorge annulaire intérieure 9, complémentaire du circlips 5,est formée sur la partie alésée 6. The rotating nut 2 comprises a bored part 6 connecting to the internal thread 7 by a shoulder 8; an inner annular groove 9, complementary to the circlip 5, is formed on the bored part 6.
Avant d'effectuer le montage, on écrase la ou les premières ondes 10 du tuyau I, situées en avant du circlips 5 précédemment mis en place. Un Joint d'étanchéi- té annulaire 11 est aussi mis en place dans l'écrou tournant 2, près de l'épaulement 8. Before mounting, the first wave or waves 10 of the pipe I, located in front of the circlip 5 previously installed, are crushed. An annular seal 11 is also placed in the swivel nut 2, near the shoulder 8.
L'extrémité du tuyau I munie du circlips 5 est enfilée dans la partie alésée 6 de l'écrou 2. Pour cela, le circlips 5 est maintenu serré extérieurement,par exemple au moyen d'un collier. La figure 2 montre les élé- ments après assemblage; les ondes écrasées 10 se trouvent alors insérées entre le joint 11 et le circlips 5. The end of the pipe I provided with the circlip 5 is threaded into the reamed part 6 of the nut 2. For this, the circlip 5 is kept tightened externally, for example by means of a collar. Figure 2 shows the elements after assembly; the crushed waves 10 are then inserted between the seal 11 and the circlip 5.
Dans une opération ultérieure, lorsque l'écrou tournant 2 est vissé sur l'embout fileté, cet embout vient plaquer le joint Il contre la ou les premières ondes 10, maintenues à l'arrière par le circlips 5 immobilisé lui-même dans la gorge 9, et l'on obtient ainsi l'étanchéité désirée. In a subsequent operation, when the rotary nut 2 is screwed onto the threaded end piece, this end piece presses the seal Il against the first wave or waves 10, held at the rear by the circlip 5 immobilized itself in the groove 9, and the desired seal is thus obtained.
Le tuyau onduleux 1 et l'écrou 2 restent, dans cette-première forme de réalisation,#émontab#es et réutilisables. The undulating pipe 1 and the nut 2 remain, in this first embodiment, # removable and reusable.
Dans le cas des figures 3 et 4, le tuyau 1 a son extrémité préalablement formée : la ou les premières ondes 10 sont écrasées, et séparées des ondes suivan- tes par une gorge plus large 4. L'écrou 2 comporte toujours une partie alésée 6, mais sur celle-ci n'eSt formée aucune gorge annulaire;l 'épaisseur de matière autour de la partie 6 est ici relativement faiblespour permettre un repoussage ou un sertissage. In the case of FIGS. 3 and 4, the pipe 1 has its end previously formed: the first wave (s) 10 are crushed, and separated from the following waves by a wider groove 4. The nut 2 always has a bored part 6, but there is no annular groove formed thereon; the thickness of material around the part 6 is here relatively small to allow pushing back or crimping.
Comme précédemment, après mise en place d'un joint d'étanchéité avenu laire Il , l'extrémité du tuyau 1 est enfilée dans la partie alésée 6 de l'écrou 2.Ensuite-, l'extrémité 12 de cet écrou 2, du caté de la partie 6, est repoussée ou sertie de manière à pénétrer dans la gorge 4. As before, after fitting a sealing ring in area Il, the end of the pipe 1 is threaded into the reamed part 6 of the nut 2. Then, the end 12 of this nut 2, of the part 6, is pushed back or crimped so as to enter the groove 4.
Les figures 5 et 6 illustrent une variante de la précédente forme de réalisation,dans laquelle le joint d'étanchéité 11 possède une forme tronconique. La première onde 10 du tuyau I est aplatie et déformée en cône, une gorge 4 de section trapézoidale la séparant de la deuxième onde. Comme précédemment, l'extrémité 12 de la partie alésée 6 de l'écrou 2 est repoussée ou sertie dans la gorge 4. Figures 5 and 6 illustrate a variant of the previous embodiment, in which the seal 11 has a frustoconical shape. The first wave 10 of the pipe I is flattened and deformed into a cone, a groove 4 of trapezoidal section separating it from the second wave. As before, the end 12 of the bored part 6 of the nut 2 is pushed back or crimped in the groove 4.
On comprend que les formes de réalisation selon les figures 3 à 6 conduisent à une simplification, et rendent l'assemblage indémontable et le joint Il imperdable, ce qui peut être considéré comme un avantage dans certaines applications. It is understood that the embodiments according to FIGS. 3 to 6 lead to a simplification, and make the assembly non-removable and the seal II captive, which can be considered an advantage in certain applications.
Comme il va de soi, l'invention ne se limite pas aux seules formes de réalisation de ce dispositif de raccordement qui ont été décrites ci-dessus, à titre d'exemples;elle en embrasse,au contraire,toutes les variantes comportant des moyens équivalents. C'est ainsi,notamment, que dans le genre de dispositif selon les figures 1 et 2, le circlips peut être remplacé par un jonc plat ou tout autre organe d'arrêt similaire,et que dans le genre de dispositif selon les figures 3 à 6, toute autre forme appropriée peut être donnée à la partie repoussée ou sertie de l'écrou tournant. It goes without saying that the invention is not limited to the sole embodiments of this connection device which have been described above, by way of examples; on the contrary, it embraces all of the variants comprising means equivalent. Thus, in particular, that in the type of device according to FIGS. 1 and 2, the circlip can be replaced by a flat rod or any other similar stop member, and that in the type of device according to FIGS. 3 to 6, any other appropriate shape can be given to the pushed back or crimped part of the rotating nut.
