Abstract

Connection sleeve for water pipe the laying or replacement of which using conventional means leads to difficulties, characterised in that its ends are provided with various connecting means at least one of which can be fitted directly onto one of the end connections of the existing pipeline whilst the other end provides continuity of the pipe fitted over a certain length into the said sleeve which is equipped at this end with a sealing means produced by tightening an external ring.

Description

La présente invention concerne un manchon de raccordement destiné en particulier à la remise en état des tuyauteries d'eau sous pression appartenant aux réseaux de distribution constitués de canalisations de petits ou moyens diamètres dont les raccordements ou piquages se font par des manchons, coudes, tes filetés, etc... The present invention relates to a connection sleeve intended in particular for the repair of pressurized water pipes belonging to the distribution networks consisting of small or medium diameter pipes whose connections or connections are made by sleeves, elbows, tes threaded, etc ...
Lorsqu'une conduite détériorée est insérée entre les pièces de raccordement et que le reste de la canalisation se trouve inaccessible comme par exemple emmurée, le remplacement de la partie détériorée nécessite par suite des extrémités filetées, la pose d'une nouvelle tuyauterie en deux parties qui sont reliées entre elles par un raccord droit. When a damaged pipe is inserted between the connecting pieces and the rest of the pipe is inaccessible such as walled, the replacement of the damaged part therefore requires threaded ends, the installation of new piping in two parts which are connected together by a straight connector.
Il existe donc le commerce de nombreux systèmes de jonction qui font appel à des moyens vissés comme par exemple des raccords dits "UNION" qui exigent que les deux parties de tuyauterie de remplacement soient coupées à des longueurs précises, ou d'autres manchons avec joints et moyens de serrage pour obtenir l'étanchéité et qui parfois fait défaut par ur.  There is therefore the trade in many joining systems which use screwed means such as for example so-called "UNION" fittings which require that the two parts of replacement piping be cut to precise lengths, or other sleeves with joints. and clamping means to obtain the seal and which is sometimes lacking by ur.
manque de guidage de deux extrémités de tuyaux emboîtés dans le manchon de raccordement.lack of guidance of two ends of pipes fitted into the connection sleeve.
La présente invention vise plus particulièrement à éliminer tous ces défauts en commençant par réutiliser le filetage d'un des raccords existant à l'une des extrémités de la canalisation puis, par sa forme particulière opposée au filetage, venir manchonner, sur une longueur importante de l'ordre de 5 fois la dimension du diamètre, l'extrémité du tuyau de remplacement sur lequel on assure l'étanchéité par un joint de forme cônique élaboré dans de la matière élastique comprimé et forcé dans un logement cônique par le serrage d'une bague filetée extérieure et d'une rondelle d'appui. The present invention aims more particularly to eliminate all these defects by first reusing the thread of one of the fittings existing at one end of the pipe and then, by its particular shape opposite the thread, come to be sleeved, over a significant length of the order of 5 times the dimension of the diameter, the end of the replacement pipe on which it is sealed by a tapered seal made from elastic material compressed and forced into a tapered housing by tightening a external threaded ring and a support washer.
Le présent dispositif présente avantageusement une manière simple et efficace pour reconstituer une conduite détériorée en conservant en partie l'alignement d'origine de la canalisation sans aucune préparation ou intervention en atelier visser la partie filetée du manchon dans le raccord existant, couper le tuyau à remplacer à une longueur sans grande précision (de l'ordre du centimètre) et de la fileter à une de ses extrémités pour la visser dans le deuxième raccord existant. The present device advantageously presents a simple and effective way to reconstruct a deteriorated pipe while retaining in part the original alignment of the pipe without any preparation or intervention in the workshop screw the threaded part of the sleeve into the existing fitting, cut the pipe to replace to a length without great precision (of the order of a centimeter) and thread it at one of its ends to screw it into the second existing fitting.
Tous les éléments en place, on serre à l'aide d'une pince genre multiprises, à griffes ou autres, la bague filetée intérieurement pour comprimer le joint afin d'obtenir l'étanchéité. All the elements in place, we tighten using a multi-pliers type pliers, with claws or others, the internally threaded ring to compress the joint in order to obtain sealing.
Four obtenir une bonne prise par la pince et éviter son rippage au moment du serrage, on a cranté la périphérie de la bague filetée intérieurement. Oven to obtain a good grip by the pliers and to avoid its ripping at the time of the tightening, one has notched the periphery of the internally threaded ring.
Le réalignement de la conduite est assuré par le long guidage interne usiné relativement précis du manchon et du tuyau emboîte sans affecter le joint d'étanchéité. The realignment of the pipe is ensured by the long, relatively precise machined internal guide of the sleeve and of the fitted pipe without affecting the seal.
On comprendre mieux la présente invention par le dessin annexé où l'on a représenté une coupe partielle d'un tel manchon constitué d'un corps (1) de forme tubulaire à deux diamtères étagés D1, D2 raccordés par une forme cônique (2). Une de ses extrémités est filetée pour venir se visser dans un raccord existant (12). La partie tubulaire de diamètre D2 est alésée avec assez de précision pour recevoir la partie manchonnée (4) de la tuyauterie (9) à remplacer. Cet alésage se termine par un cône (5) tandis qu'à l'extérieur, le manchon reçoit un filetage (6) coopérant avec une bague filetée (8) munie à sa périphérie d'un crantage (8'). The present invention can be better understood by the appended drawing in which there is shown a partial section of such a sleeve constituted by a body (1) of tubular shape with two stepped diameters D1, D2 connected by a conical shape (2) . One of its ends is threaded to be screwed into an existing fitting (12). The tubular part of diameter D2 is reamed with sufficient precision to receive the sleeved part (4) of the piping (9) to be replaced. This bore ends in a cone (5) while outside, the sleeve receives a thread (6) cooperating with a threaded ring (8) provided at its periphery with a notch (8 ').
Un joint (7) de forme tronconique en matière élastique est poussé, au moment du serrage de ladite bague crantée-filetée, dans le logement conique (5) par l'intermédiaire d'une rondelle (9 > .  A gasket (7) of frustoconical shape made of elastic material is pushed, when tightening said notched-threaded ring, into the conical housing (5) by means of a washer (9>.
L'autre extrémité de la tuyauterie de remplacement (10) a été vissée dans l'autre raccord existant (11). The other end of the replacement piping (10) was screwed into the other existing fitting (11).
Le manchon tel que représenté est équipé d'un piquage (13) permettant l'installation d'un robinet ou autre appareil, ou le départ d'une nouvelle canalisation, ces deux exemples n'étant pas limitatifs. The sleeve as shown is equipped with a nozzle (13) allowing the installation of a tap or other device, or the start of a new pipe, these two examples not being limiting.
Toutes les combinaisons possibles standardisées et normalisées dans le domaine de la tuyauterie sont applicables à ce manchon.  All possible standardized and standardized combinations in the field of piping are applicable to this sleeve.
