Description
Joint de dilatation pour l'assemblage souple et étanche de deux tuyaux La présente invention a pour objet un joint de dilatation pour l'assemblage souple et étanche de deux tuyaux, notamment en matière plastique, dont le premier présente, à son extrémité, un manchon dans lequel le second tuyau est susceptible de pénétrer.
Ce joint est caractérisé par le fait qu'il comprend une garniture d'étanchéité en matériau élastique mon tée sur le second tuyau et comportant deux lèvres coniques opposées enserrant élastiquement ledit se cond tuyau, cette garniture présentant en outre un épaulement périphérique susceptible d'être centré et bloqué entre une face annulaire de l'extrémité dudit manchon, constituant un épaulement fixe de retenue, et un logement correspondant de l'intérieur d'une bague mobile coulissant sur ledit second tuyau.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de la présente invention.
La fig. 1 représente le joint de dilatation monté et vu en coupe longitudinale.
La fig. 2 représente également en coupe longitu dinale le joint de dilatation partiellement démonté. La garniture 1 du joint de dilatation, en maté riau élastique, porte un épaulement périphérique 2 destiné à être centré et bloqué entre un épaulement fixe de retenue constitué par la face extrême 6 d'un manchon 4 prévu à l'extrémité du premier tuyau, et un logement correspondant <B>10</B> prévu à l'intérieur d'une bague mobile 3 coulissant sur le second tuyau 9.
La bague mobile 3 est munie d'un filetage interne 5, coopérant avec un filetage externe 5' prévu sur la périphérie du manchon 4, pour permettre le blocage de l'épaulement 2 et, partant, le positionnement de la garniture 1 sur les deux tuyaux. La garniture 1 comporte, d'autre part, une lèvre conique inférieure 7 et une lèvre conique supérieure opposée 8, qui enserrent élastiquement le second tuyau 9.
Les avantages du joint de dilatation représenté sont multiples.
Le blocage de ,l'épaulement 2 de la garniture par serrage de la bague mobile 3 sur le manchon 4 permet tout d'abord de positionner et stabiliser la garniture 1 qui ne peut plus se déplacer. En outre, la pression exercée sur l'épaulement 2 fait légère ment saillir la garniture 1 qui enserre avec plus de force le tuyau 9 en assurant un raccordement étan che.
Malgré ce blocage de la garniture 1, l'élasti cité des lèvres coniques 7 et 8 reste suffisante pour rattraper une éventuelle inégalité ou une petite varia tion de diamètre du tuyau 9 et permettre de com penser la dilatation axiale A ou transversale B de ce tuyau 9. Comme représenté à la fig. 2, il est pos sible, en dévissant la bague mobile 3, de dégager la garniture 1 pour déplacer axialement le tuyau 9, ce qui permet la visite, le nettoyage et même le grais sage du joint de dilatation.
La mise en place est facilitée par le centrage obtenu par le vissage de la bague mobile 3 sur le filetage 5' du manchon récepteur 4.
Le décapelage et le désemboitement sont rendus impossibles par le large coefficient de sécurité de dilatation et le serrage de la garniture sur une très grande surface d'adhérence compensant tout défaut du tuyau 9.
L'application de ce joint de dilatation s'étend à toutes les canalisations et conduites de fluides liqui des et gazeux, et même de produits pulvérulents ou pâteux.
Expansion joint for the flexible and tight assembly of two pipes The present invention relates to an expansion joint for the flexible and tight assembly of two pipes, in particular of plastic material, the first of which has, at its end, a sleeve into which the second pipe is liable to enter.
This seal is characterized by the fact that it comprises a sealing gasket of elastic material mounted on the second pipe and comprising two opposite conical lips elastically enclosing said second pipe, this gasket also having a peripheral shoulder capable of being centered and locked between an annular face of the end of said sleeve, constituting a fixed retaining shoulder, and a corresponding housing inside a movable ring sliding on said second pipe.
The accompanying drawing shows, by way of example, one embodiment of the present invention.
Fig. 1 shows the mounted expansion joint and seen in longitudinal section.
Fig. 2 also shows in longitudinal section the partially dismantled expansion joint. The gasket 1 of the expansion joint, made of resilient material, carries a peripheral shoulder 2 intended to be centered and blocked between a fixed retaining shoulder formed by the end face 6 of a sleeve 4 provided at the end of the first pipe, and a corresponding housing <B> 10 </B> provided inside a movable ring 3 sliding on the second pipe 9.
The movable ring 3 is provided with an internal thread 5, cooperating with an external thread 5 'provided on the periphery of the sleeve 4, to allow the locking of the shoulder 2 and, therefore, the positioning of the gasket 1 on the two pipes. The gasket 1 comprises, on the other hand, a lower conical lip 7 and an opposite upper conical lip 8, which elastically enclose the second pipe 9.
The advantages of the expansion joint shown are multiple.
The blocking of the shoulder 2 of the lining by clamping the movable ring 3 on the sleeve 4 first of all makes it possible to position and stabilize the lining 1 which can no longer move. In addition, the pressure exerted on the shoulder 2 causes the gasket 1 to protrude slightly, which more strongly encloses the pipe 9, ensuring a watertight connection.
Despite this blockage of the seal 1, the elasticity of the conical lips 7 and 8 remains sufficient to make up for any unevenness or a small variation in the diameter of the pipe 9 and to make it possible to compensate for the axial expansion A or transverse B of this pipe. 9. As shown in FIG. 2, it is possible, by unscrewing the movable ring 3, to release the gasket 1 in order to move the pipe 9 axially, which allows the inspection, cleaning and even the wise greasing of the expansion joint.
The positioning is facilitated by the centering obtained by screwing the movable ring 3 on the thread 5 'of the receiving sleeve 4.
The stripping and dismantling are made impossible by the large expansion safety coefficient and the tightening of the lining over a very large adhesion surface compensating for any defect in the pipe 9.
The application of this expansion joint extends to all pipes and conduits of liquid and gaseous fluids, and even of powdery or pasty products.
