DISPOSITIF D'ARTICULATION ETANCHE POUR TUYAUX CYLINDRIQUES
La présente invention concerne un dispositif d'articulation étanche pour tuyaux cylindriques en matière synthétique.SEALED ARTICULATION DEVICE FOR CYLINDRICAL PIPES
The present invention relates to a sealed articulation device for cylindrical pipes made of synthetic material.
Les tronçons de tuyaux extrudés sont en général rigides et ne permettent pas de suivre des courbes de faible rayon de courbure. Pour pallier cet inconvénient, on a développé des éléments souples composés d'anneaux emboîtes les uns dans les autres et présentant entre eux un
Jeu suffisant pour permettre de former des coudes ou de suivre des courbes de faible rayon. Ces éléments souples sont bien adaptés à toutes les applications ou l'étanchéité n'est pas requise, étant donné qu'il est impossible d'assurer l'étanchéité entre les segments cylindriques formant ces éléments, meme si, comme l'ont montré différents essais, on les équipe de Joints toriques ou profilés. De ce fait, l'utilisation de ce type d'éléments souples n'est pas envisageable pour de très nombreuses applications ou l'étanchéité est une caractéristique indispensable.Il en est ainsi pour toutes les applications relatives à l'approvisionnement ou l'évacuation de liquides, par exemple pour la mise en place ou la réparation de canalisations transportant des eaux claires ou des eaux usées.The sections of extruded pipes are generally rigid and do not allow curves of small radius of curvature to be followed. To overcome this drawback, flexible elements have been developed composed of rings fitted into each other and having between them a
Sufficient play to allow elbows to form or to follow curves of small radius. These flexible elements are well suited to all applications where sealing is not required, since it is impossible to ensure sealing between the cylindrical segments forming these elements, even if, as shown by different tests, we equip them with O-rings or profiles. As a result, the use of this type of flexible element cannot be envisaged for many applications where sealing is an essential characteristic. This is the case for all applications relating to supply or disposal. liquids, for example for the installation or repair of pipes carrying clear water or waste water.
Il en est de meme pour la protection des câbles électriques ou des lignes téléphoniques.It is the same for the protection of electric cables or telephone lines.
La présente invention se propose de pallier cet inconvénient en réalisant un dispositif d'articulation étanche qui permet de raccorder entre eux des tronçons de conduites de canalisations rectilignes rigides, au moyen de tronçons courbes de relativement petit rayon de courbure.The present invention proposes to overcome this drawback by providing a sealed articulation device which makes it possible to connect between them sections of rigid rectilinear pipe conduits, by means of curved sections of relatively small radius of curvature.
Ce but est atteint par le dispositif d'articulation selon l'invention, caractérisé en ce qu'il comprend au moins un premier élément d'articulation ayant un profil partiellement sphérique et au moins un second élément d'articulation ayant également un profil partiellement sphérique, le premier élément d'articulation ayant un diamètre intérieur sensiblement égal au diamètre extérieur du second élément d'articulation, de telle manière que le second élément d'articulation puisse etre emboîté à l'intérieur du premier élément d'articulation afin de former une rotule.This object is achieved by the articulation device according to the invention, characterized in that it comprises at least a first articulation element having a partially spherical profile and at least a second articulation element also having a partially spherical profile , the first articulation element having an internal diameter substantially equal to the external diameter of the second articulation element, so that the second articulation element can be fitted inside the first articulation element in order to form a patella.
Selon une forme de réalisation particulière, l'un au moins des deux éléments d'articulation comporte des moyens d'étanchéité agencés pour frotter contre la surface d'appui de l'autre élément d'articulation.According to a particular embodiment, at least one of the two articulation elements comprises sealing means arranged to rub against the bearing surface of the other articulation element.
Selon une autre forme de réalisation particulière, lesdits moyens d'étanchéité comprennent au moins une protubérance annulaire ménagée sur la surface intérieure de l'un des éléments d'articulation et agencée pour frotter contre la surface d'appui de l'autre élément d'articulation.According to another particular embodiment, said sealing means comprise at least one annular protuberance formed on the inner surface of one of the articulation elements and arranged to rub against the bearing surface of the other element of joint.
Selon une forme de réalisation avantageuse, lesdits moyens d'étanchéi- té comprennent au moins un Joint élastomère annulaire disposé dans un logement ménagé dans l'un des éléments d'articulation et dimensionné pour frotter contre la surface d'appui de l'autre élément d'articulation.According to an advantageous embodiment, said sealing means comprise at least one annular elastomer seal placed in a housing formed in one of the articulation elements and dimensioned to rub against the bearing surface of the other element of articulation.
Le premier élément d'articulation peut comporter au moins un logement ménagé a sa surface intérieure, agencé pour contenir au moins un Joint d'étanchéité annulaire, ce Joint étant dimensionné pour prendre appui sur la surface périphérique du second élément d'articulation.The first articulation element may comprise at least one housing formed on its internal surface, arranged to contain at least one annular seal, this seal being dimensioned to bear on the peripheral surface of the second articulation element.
Le second élément d'articulation peut aussi comporter au moins un logement ménagé à sa surface extérieure, agencé pour contenir au moins un Joint d'étanchéité annulaire, ce Joint étant dimensionné pour prendre appui sur la surface intérieure du premier élément d'articulation.The second articulation element may also comprise at least one housing formed on its external surface, arranged to contain at least one annular seal, this seal being dimensioned to bear on the interior surface of the first articulation element.
Selon une variante combinant les deux réalisations précédentes, le premier élément d'articulation comporte au moins un logement ménagé à sa surface intérieure agencé pour contenir au moins un Joint d'étanchéité annulaire, ce Joint étant dimensionné pour prendre appui sur la surface périphérique du second élément d'articulation et le second élément d'articulation comporte au moins un logement ménagé à sa surface extérieure, agencé pour contenir au moins un Joint d'étanchéité annulaire, ce Joint étant dimensionné pour prendre appui sur la surface intérieure du premier élément d'articulation.According to a variant combining the two previous embodiments, the first articulation element comprises at least one housing formed on its inner surface arranged to contain at least one annular seal, this seal being dimensioned to bear on the peripheral surface of the second articulation element and the second articulation element comprises at least one housing formed on its outer surface, arranged to contain at least one annular seal, this seal being dimensioned to bear on the interior surface of the first element joint.

Selon un autre mode de réalisation, ledit premier élément d'articulation et ledit second élément d'articulation sont solidaires chacun d'un tronçon tubulaire cylindrique agencé pour être raccordé par emboltement à l'extrémité d'un tuyau cylindrique.According to another embodiment, said first articulation element and said second articulation element are each secured to a cylindrical tubular section arranged to be connected by embolism to the end of a cylindrical pipe.

FIG. 6 illustrates a method of assembling several modules intended to form an articulation device according to the invention, and
FIGS. 7 and 8 illustrate two neighboring variants of the device illustrated in FIG. 1.
En référence à la figure 1, le dispositif d'articulation 10 se compose d'un premier élément d'articulation 11, ayant un profil partiellement sphérique et d'un second élément d'articulation 12 ayant également un profil partiellement sphérique. Le diamètre intérieur du premier élément d'articulation 11 est sensiblement égal au diamètre extérieur du second élément d'articulation 12, de telle manière que le second élément d'articulation embolie dans le premier constitue une rotule.Referring to Figure 1, the articulation device 10 consists of a first articulation element 11, having a partially spherical profile and a second articulation element 12 also having a partially spherical profile. The internal diameter of the first articulation element 11 is substantially equal to the external diameter of the second articulation element 12, so that the second articulation element embolished in the first constitutes a ball joint.
L'étanchéité entre les deux éléments d'articulation 11 et 12 est obtenue par un Joint torique 13 en élastomère, qui pourrait également être remplacé par un Joint annulaire profile ayant une section transversale symétrique par rapport a son plan médian. Le Joint 13 est disposé à l'intérieur d'un logement 14 ménagé dans la paroi de l'élé- ment d'articulation 11. Ce logement est ouvert vers l'intérieur de l'élément 11, et le Joint d'étanchéité 13 est dimensionne de telle manière qu'il prenne appui sur la surface périphérique du second élément d'articulation 12. The seal between the two articulation elements 11 and 12 is obtained by an O-ring 13 made of elastomer, which could also be replaced by a profiled annular seal having a cross section symmetrical with respect to its median plane. The seal 13 is disposed inside a housing 14 formed in the wall of the articulation element 11. This housing is open towards the interior of the element 11, and the seal 13 is dimensioned in such a way that it bears on the peripheral surface of the second articulation element 12.
Dans l'exemple illustré, les deux éléments d'articulation sont raccordés chacun a un tronçon cylindrique respectivement 11a et 12a. L'ensemble de ces éléments à savoir le premier élément d'articulation 11. In the example illustrated, the two articulation elements are each connected to a cylindrical section 11a and 12a respectively. All of these elements, namely the first articulation element 11.
le second élément d'articulation 12 et les deux tronçons cylindriques lia et 12a sont dimensionnés de telle manière que la déviation maximale autorisée soit de l'ordre de 10 à 152. Il est évident qu'une réduction de diamètre des tronçons cylindriques permettrait d'augmen ter l'angle d'articulation de la rotule.the second articulation element 12 and the two cylindrical sections 11a and 12a are dimensioned in such a way that the maximum authorized deviation is of the order of 10 to 152. It is obvious that a reduction in diameter of the cylindrical sections would make it possible to increase the angle of articulation of the patella.
Le tronçon cylindrique lia est raccordé à l'une de ses extrémités au premier élément d'articulation 11 et porte à son autre extrémité un second élément d'articulation 12' identique à l'élément d'articulation 12. De façon similaire, le tronçon cylindrique 12a est raccordé à une de ses extrémités au second élément d'articulation 12 et porte à son autre extrémité un premier élément d'articulation 11' identique au premier élément d'articulation 11.L'ensemble compose d'un premier élément d'articulation 11, d'un tronçon cylindrique lia et d'un second élément d'articulation 12' constitue un module qui, comme le montre la fig. 1, peut être accouple avec un second module identique, préalablement retourné, composé d'un second élément d'articulation 12, d'un tronçon cylindrique 12a et d'un premier élément d'articulation il'. The cylindrical section 11a is connected at one of its ends to the first articulation element 11 and carries at its other end a second articulation element 12 'identical to the articulation element 12. Similarly, the section cylindrical 12a is connected at one of its ends to the second articulation element 12 and carries at its other end a first articulation element 11 'identical to the first articulation element 11.The assembly consists of a first articulation 11, a cylindrical section 11a and a second articulation element 12 'constitutes a module which, as shown in FIG. 1, can be coupled with a second identical module, previously turned over, composed of a second articulation element 12, of a cylindrical section 12a and of a first articulation element 11 '.
Comme le montre de façon schématique la fig. 6, le nombre des modules pouvant être accouplés n'est pas limité à deux mais peut être choisi en fonction du tronçon curviligne de canalisation étanche que l'on souhaite realiser.As shown schematically in fig. 6, the number of modules that can be coupled is not limited to two but can be chosen as a function of the curvilinear section of sealed pipe that it is desired to produce.
La figure 2 représente une autre forme de réalisation d'un dispositif d'articulation 20 qui se compose comme précédemment d'un premier élément d'articulation 21 et d'un second élément d'articulation 22 emboîté dans le premier. Dans cet exemple de réalisation, c'est le second élément d'articulation 22, et non plus le premier comme dans l'exemple précédent, qui porte le Joint annulaire d'étanchéité disposé à l'intérieur d'un logement 22 ménagé dans l'épaisseur de la paroi du second élément d'articulation 22. Le premier élément d'articulation 21 est localise à une extrémité d'un tronçon cylindrique 21a dont l'autre extrémité porte un second élément d'articulation 22' identique à l'élément d'articulation 22 décrit ci-dessus.De façon analogue, ce second élément d'articulation 22 est lié à un tronçon cylindrique 22a dont l'autre extrémité porte un premier élément d'articulation 21' identique au premier élément d'articulation 21.FIG. 2 shows another embodiment of an articulation device 20 which consists, as before, of a first articulation element 21 and of a second articulation element 22 fitted into the first. In this exemplary embodiment, it is the second articulation element 22, and no longer the first as in the previous example, which carries the annular seal placed inside a housing 22 formed in the thickness of the wall of the second articulation element 22. The first articulation element 21 is located at one end of a cylindrical section 21a, the other end of which carries a second articulation element 22 'identical to the element articulation 22 described above. Similarly, this second articulation element 22 is linked to a cylindrical section 22a, the other end of which carries a first articulation element 21 'identical to the first articulation element 21.
On obtient comme précédemment des modules emboitables qui permettent de réaliser une canalisation curviligne étanche.As previously obtained, interlocking modules which make it possible to produce a tight curvilinear pipe.
Pour parfaire l'étanchéité, il serait possible de prévoir plusieurs
Joints d'étanchéité identiques ou différents, disposés indifféremment dans des logements ménagés en partie ou en totalité dans l'épaisseur du second élément d'articulation (voir fig. 2), ou en partie ou totalement dans des logements solidaires du premier élément d'articulation (voir fig. 1).To complete the seal, it would be possible to provide several
Identical or different seals, arranged indifferently in housings formed partly or entirely in the thickness of the second articulation element (see fig. 2), or partly or totally in housings integral with the first element articulation (see fig. 1).
Selon un mode de réalisation avantageux, il serait possible d'équiper des tuyaux cylindriques rectilignes d'éléments d'articulation identiques à ceux décrits ci-dessus. Ce mode de réalisation est illustré par la fig. 3, qui représente deux tuyaux cylindriques 30 et 31 dont chaque extrémité porte un premier élément d'articulation 30a, respectivement 31a et dont l'autre extrémité porte un second élément d'articulation 30b respectivement 31b. Dans l'exemple représenté, les élé- ments d'articulation sont identiques à ceux de la fig. 1. Le premier élément d'articulation 31a solidaire du tuyau cylindrique 31, est destiné a être ajusté sur le second élément d'articulation 30b du second tuyau cylindrique 30, dans le but de former une rotule de liaison entre ces deux tuyaux.According to an advantageous embodiment, it would be possible to equip straight cylindrical pipes with articulation elements identical to those described above. This embodiment is illustrated in FIG. 3, which represents two cylindrical pipes 30 and 31, each end of which carries a first articulation element 30a, respectively 31a and the other end of which carries a second articulation element 30b and 31b respectively. In the example shown, the articulation elements are identical to those of FIG. 1. The first articulation element 31a integral with the cylindrical pipe 31, is intended to be adjusted on the second articulation element 30b of the second cylindrical pipe 30, in order to form a ball joint between these two pipes.
La figure 4 illustre une variante du dispositif illustre par la fig.FIG. 4 illustrates a variant of the device illustrated in FIG.
3. Dans cette réalisation deux tuyaux cylindriques 40 et 41 peuvent être équipés chacun d'un premier élément d'articulation 40a respectivement villa et d'un second élément d'articulation 40b respectivement 41b. Ces éléments d'articulation comportent chacun un embout 42 ayant une forme sensiblement cylindrique et équipé d'un logement 43 agencé pour contenir un Joint d'étanchéité 44. De cette manière, les éléments d'articulation individuels peuvent être adaptés de façon étanche aux extrémités de tuyaux ayant une forme parfaitement cylindrique.3. In this embodiment, two cylindrical pipes 40 and 41 can each be equipped with a first articulation element 40a respectively villa and with a second articulation element 40b respectively 41b. These articulation elements each comprise an end piece 42 having a substantially cylindrical shape and equipped with a housing 43 arranged to contain a seal 44. In this way, the individual articulation elements can be adapted in a sealed manner at the ends. of pipes having a perfectly cylindrical shape.
La figure 5 illustre une variante de cette réalisation dans laquelle le manchon 42' solidaire d'un premier élément d'articulation 40'a présente une forme cylindrique alors que l'extrémité du tuyau 40' est prémanchonné de manière à réaliser un logement 43' destiné à contenir un Joint d'étanchéité annulaire 44'.FIG. 5 illustrates a variant of this embodiment in which the sleeve 42 ′ secured to a first articulation element 40 ′ a has a cylindrical shape while the end of the pipe 40 ′ is pre-connected so as to produce a housing 43 ′ intended to contain an annular seal 44 '.
Selon une autre forme de réalisation , les manchons 42' pourraient être soudés directement à l'extrémité des tuyaux cylindriques, ce qui supprimerait l'obligation d'utiliser un Joint annulaire pour réaliser l'étanchéité entre les tuyaux et les éléments d'alimentation rapportes.According to another embodiment, the sleeves 42 ′ could be welded directly to the end of the cylindrical pipes, which would eliminate the obligation to use an annular seal to seal between the pipes and the attached supply elements .
La figure 6 illustre un mode d'assemblage permettant de réaliser une articulation à l'aide de trois modules 50, 51 et 52 identiques entre eux.FIG. 6 illustrates an assembly method making it possible to produce a joint using three modules 50, 51 and 52 which are identical to each other.
La figure 7 illustre un dispositif d'articulation 10 dont la construction est très voisine de celle du dispositif d'articulation représenté par la fig. 1. Il se compose d'un premier élément 11 et d'un second élément 12 agences pour s'embolter de manière à former une rotule. Le dispositif illustré par la fig. 1 comprenait un premier élément 11 pourvu d'un logement 14 à l'intérieur duquel était disposé un Joint d'étanchéité 13. Le dispositif d'articulation représenté par la fig. 7 diffère de celui illustre par la fig. 1 en ce que le premier élément d'articulation 11 est dépourvu de tout logement conçu pour contenir un
Joint d'étanchéité.On estime que pour certaines applications la surface d'appui 60 de la rotule, définie par la surface intérieure du premier element d'articulation 11 et la surface extérieure du second élément d'articulation 12, présente une étanchéité suffisante pour pouvoir se passer du Joint d'étanchéité.FIG. 7 illustrates an articulation device 10, the construction of which is very close to that of the articulation device shown in FIG. 1. It consists of a first element 11 and a second element 12 agencies to embolish themselves so as to form a patella. The device illustrated in FIG. 1 included a first element 11 provided with a housing 14 inside which was disposed a sealing gasket 13. The articulation device represented by FIG. 7 differs from that illustrated in FIG. 1 in that the first articulation element 11 is devoid of any housing designed to contain a
It is estimated that for certain applications the bearing surface 60 of the ball joint, defined by the interior surface of the first articulation element 11 and the exterior surface of the second articulation element 12, presents a sufficient seal for ability to do without seal.
La figure 8 représente une autre variante dépourvue de Joint d'étanchéité. L'articulation 10 se compose comme précédemment d'un premier élément d'articulation 11 et d'un second élément d'articulation 12. Dans ce cas, la surface extérieure du second élément d'articulation 12 est pourvue d'une ou de plusieurs protubérances annulaires 61 qui peuvent être constituées par de simples bourrelets arrondis ou par des languettes annulaires destinées à former de véritables segments d'étanchéité qui balayent la surface de contact 60 définie dans ce cas par la surface intérieure du premier élément d'articulation 11. Figure 8 shows another variant devoid of seal. The articulation 10 is composed as before of a first articulation element 11 and of a second articulation element 12. In this case, the external surface of the second articulation element 12 is provided with one or more annular protuberances 61 which can be constituted by simple rounded beads or by annular tongues intended to form real sealing segments which sweep the contact surface 60 defined in this case by the interior surface of the first articulation element 11.
Il est bien entendu que ces moyens d'étanchéité pourraient être utilises sur toutes les variantes illustrées notamment par les figures 3 å 5. Par ailleurs, les éléments d'articulation montés ou solidaires des extrémités de tronçons de tuyaux rectilignes pourraient également être adaptes aux extrémités de bifurcations en forme de Y destinées à réaliser une dérivation sur une conduite d'eau ou une canalisation quelconque.It is understood that these sealing means could be used on all the variants illustrated in particular by FIGS. 3 to 5. Furthermore, the articulation elements mounted or integral with the ends of straight pipe sections could also be adapted to the ends Y-shaped bifurcations intended to make a diversion on a water pipe or any pipe.
