Abstract

The joint for repairing leaks occurring between pipe connections comprises an elastomer joint which is applied in the leak location and a rigid piece (2) which compresses the joint. The rigid piece can be adjusted to adapt as closes as possible to the pipe by means of a removable piece (4) allowing the obtaining of a hole (5) with dimensions greater than the diameter (6) of the bolts used.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

DESCRIPTION Joint de réparation ou de rénovation réglable Sur les réseaux de transport de fluide datant de nombreuses années, apparaissent en général des fuites permettant au liquide véhiculé de s'échapper. Ces fuites apparaissent dans tous les cas au niveau des raccordements des tuyaux et non sur les tuyaux eux mêmes. Ce phénomène s'explique par la simple raison que le joint assurant l'étanchéité (élastomère, plomb...) se dégrade, du fait de sa propre composition et des mouvements de tuyauterie, plus vite que le tuyau lui même. DESCRIPTION Adjustable repair or renovation joint On fluid transport networks dating back many years, leaks generally appear allowing the transported liquid to escape. These leaks appear in all cases at the pipe connections and not on the pipes themselves. This phenomenon is explained by the simple reason that the seal ensuring the seal (elastomer, lead ...) degrades, due to its own composition and movements of the piping, faster than the pipe itself.

Il existe des systèmes permettant de réparer ces fuites, mais il présentent l'inconvénient, soit de ne pas pouvoir s'installer sur des larges tolérances de canalisation, soit sont compliqués et longs de mise en oeuvre du fait des multiples réglages qu'ils proposent. There are systems to repair these leaks, but they have the drawback either of not being able to install over large pipe tolerances, or are complicated and time-consuming due to the multiple adjustments they offer. .

Le brevet selon l'invention permet de remédier à ces inconvénients, en offrant une pièce permettant de s'adapter rapidement au diamètre de la canalisation. La capacité de réglage s'obtenant par des trous (5) de dimensions supérieures au diamètre (6) de la boulonnerie utilisée, lesdits trous (5) étant réduits par une pièce amovible (4). Ainsi, au besoin, le retrait de ladite pièce amovible (4) permet d'augmenter la dimension de la pièce (2). Cette capacité d'augmentation est représentée par la lettre"R"sur la figure 3. The patent according to the invention makes it possible to remedy these drawbacks, by providing a part allowing rapid adaptation to the diameter of the pipe. The adjustment capacity is obtained by holes (5) of dimensions greater than the diameter (6) of the bolts used, said holes (5) being reduced by a removable part (4). Thus, if necessary, the removal of said removable part (4) makes it possible to increase the dimension of the part (2). This increase capacity is represented by the letter "R" in FIG. 3.

En référence aux dessins, La figure 1 représente en coupe le joint selon l'invention sur un raccordement par bague La figure 2 représente en coupe le joint selon l'invention sur un raccordement par emboîtement. With reference to the drawings, FIG. 1 shows in section the seal according to the invention on a ring connection. FIG. 2 shows in section the seal according to the invention on a socket connection.

La figure 3 représente le détail de l'invention permettant au joint de s'adapter sur des conduites de différents diamètre, tout en assurant l'étanchéité. Figure 3 shows the detail of the invention allowing the joint to adapt to pipes of different diameter, while ensuring sealing.

Suivant le mode opératoire décrit ci-dessous, l'opérateur assure le résultat de la réparation ou de la rénovation de la conduite : * nettoyage de la canalisation au niveau de la zone de raccordement à réparer ou à rénover. According to the operating mode described below, the operator ensures the result of the repair or renovation of the pipe: * cleaning of the pipe at the connection area to be repaired or renovated.

* pose du joint élastomère (1) * mise en place des pièces rigides (2)

Figure img00010001

* réglages desdites pièces (2) au plus près de la conduite en enlevant ou non la pièce amovible (4). * installation of the elastomer seal (1) * installation of rigid parts (2)
Figure img00010001

* adjustments of said parts (2) closer to the pipe by removing or not the removable part (4).

Selon un mode particulier de fabrication, la pièce amovible (4) peut être une partie de la pièce rigide (2) que l'on casse de manière irréversible.According to a particular manufacturing method, the removable part (4) can be a part of the rigid part (2) which is broken irreversibly.
