Description
OBJET DE L'INVENTION
La présente demande de brevet a pour objet un procédé pour effectuer des dérivations sur des conduits de fluides sous pression, présentant des avantages et des innovations notables par rapport aux procédés actuellement utilisés pour un but égal ou similaire.OBJECT OF THE INVENTION
The present patent application relates to a method for making derivations on pressurized fluid conduits, presenting significant advantages and innovations compared to the methods currently used for an equal or similar purpose.
Plus concrètement, dans cette invention, on a conçu un procédé permettant de connecter le tube de dérivation directement au conduit du réseau, sans qu'il soit nécessaire d'utiliser des accessoires intermédiaires, de sorte que tant l'accessoire de dérivation que le filet situé entre le collier et cet accessoire sont éliminés, en réussissant ainsi à économiser du matériel, à faciliter le montage et à obtenir une union plus fiable du fait de l'élimination du filet entre le collier et l'accessoire puisque le filet doit être hermétique aux fuites à la fin de la pose. More concretely, in this invention, a method has been devised allowing the branch tube to be connected directly to the network conduit, without the need to use intermediate accessories, so that both the branch accessory and the net located between the collar and this accessory are eliminated, thus succeeding in saving material, facilitating assembly and obtaining a more reliable union due to the elimination of the net between the collar and the accessory since the net must be hermetic leaks at the end of the installation.
ÉTAT ACTUEL DE LA TECHNIQUE
I1 faut dire que, dans l'état actuel de la technique, pour réaliser, sous pression, des dérivations à un réseau de tuyaux, on connaît un système composé d'un collier comprenant des moyens d'obturation nécessaires pour effectuer la dérivation sous pression avec, à son extrémité, un filet femelle, auquel est vissé un coude ou un autre type d'accessoire, auquel le tube de dérivation est connecté.CURRENT STATE OF THE ART
I1 must say that, in the current state of the art, to realize, under pressure, diversions to a network of pipes, there is known a system composed of a collar comprising closure means necessary to perform the diversion under pressure with, at its end, a female thread, to which is screwed an elbow or another type of accessory, to which the bypass tube is connected.
On connaît aussi un autre système utilisant un collier du type décrit ci-dessus, mais qui se termine par un tube auquel il faut adapter un accessoire permettant de continuer la dérivation. Another system is also known using a collar of the type described above, but which ends in a tube to which an accessory must be adapted allowing the bypass to continue.
De même, on connaît un autre système composé d'un collier sans moyens d'obturation, auquel on connecte un dispositif permettant la connexion sous pression et auquel on devra connecter ensuite un accessoire permettant de réaliser la connexion du tube de dérivation. Similarly, another system is known which is made up of a collar without closure means, to which a device allowing connection under pressure is connected and to which an accessory allowing connection of the bypass tube must then be connected.
DESCRIPTION DE L'INVENTION
Le procédé pour effectuer des dérivations sur des conduits de fluides, sous pression, objet de la présente invention, est composé d'un collier fixé sur le conduit du réseau par l'un des systèmes traditionnels.DESCRIPTION OF THE INVENTION
The process for carrying out diversions on conduits of fluids, under pressure, object of the present invention, is composed of a collar fixed on the conduit of the network by one of the traditional systems.
La moitié supérieure de ce collier présente une fente permettant d'introduire une spatule et présente une géométrie adéquate pour permettre de recevoir en son intérieur un joint multiple qui assure l'étanchéité avec le tuyau et avec la spatule et un joint torique qui assure l'étanchéité avec le tube de dérivation. The upper half of this collar has a slot allowing the introduction of a spatula and has an adequate geometry to allow it to receive inside its multiple seal which seals with the pipe and with the spatula and an O-ring which ensures the tightness with the bypass tube.
De même, à la partie supérieure, on place un joint torique qui assure l'étanchéité avec le tube de dérivation ; une bride qui accrochera le tube pour empêcher qu'il se dégage une fois monté, cette bride comprenant, en son intérieur, des moyens de fixation et, en son extérieur, une surface conique coupée dans le sens axial afin qu'elle puisse se déformer et s'adapter au tube facilement ; une rondelle séparant le joint torique et la bride. Similarly, at the top, an O-ring is placed which seals with the bypass tube; a flange which will hook the tube to prevent it from disengaging once mounted, this flange comprising, inside, fixing means and, outside, a conical surface cut in the axial direction so that it can deform and adapt to the tube easily; a washer separating the O-ring and the flange.
A sa partie extérieure, on monte un écrou qui se visse sur la surface extérieure du collier et présente en son intérieur une surface conique coïncidant avec celle de la bride, et qui reçoit en son intérieur un joint torique, ce qui permet une double garantie d'étanchéité lorsque l'ensemble est monté ; et un joint torique dont le but est le même. At its outer part, a nut is mounted which is screwed onto the outer surface of the collar and has inside a conical surface coinciding with that of the flange, and which receives an O-ring inside, which allows a double guarantee of 'tightness when the assembly is mounted; and an O-ring with the same purpose.
Le procédé de pose consiste, en premier lieu, à fixer fermement la bride sur le conduit sur lequel on veut réaliser la dérivation. Ensuite, on enlève de ce collier le joint torique, la rondelle, la bride et l'écrou et, en intercalant une pièce filetée d'assemblage, on installe sur le collier un outil adéquat pour percer le tuyau. Cet outil doit disposer des éléments d'étanchéité nécessaires afin que, une fois le conduit percé, il n'y ait pas de fuites à l'extérieur. The installation process consists, first of all, of firmly fixing the flange on the conduit on which one wants to make the bypass. Then, remove from this collar the O-ring, the washer, the flange and the nut and, inserting a threaded assembly piece, install on the collar a suitable tool for drilling the pipe. This tool must have the necessary sealing elements so that, once the conduit is drilled, there are no leaks outside.
Après perçage du conduit et retrait de l'outil de coupe, on introduit la spatule qui glisse sur le joint multiple, ce qui permet de retirer l'outil de perçage sans provoquer de fuites, et on monte sur le collier les pièces qui avaient été enlevées, c'est-à-dire le joint torique, la rondelle, la bride et l'écrou, en vissant l'écrou jusqu'à ce qu'il touche la spatule mais sans serrer ensuite, on introduit le tube de dérivation jusqu'à ce qu'il bute sur une saillie intérieure du collier ou sur la spatule elle-même. After drilling the duct and removing the cutting tool, insert the spatula which slides over the multiple joint, which allows the drilling tool to be removed without causing leaks, and the parts that had been removed are mounted on the collar. removed, i.e. the O-ring, the washer, the flange and the nut, by screwing the nut until it touches the spatula but without then tightening, insert the bypass tube until 'that it abuts on an inner projection of the collar or on the spatula itself.
Lorsque le tube de dérivation est fermé à l'autre extrémité par une valve ou tout autre moyen d'obturation, on retire la spatule de sorte que la pression qui envahit l'intérieur du tube de dérivation le pousse vers l'extérieur, le rendant prisonnier de la bride qui se ferme sur lui par action de ses surfaces coniques, l'ensemble restant avantageusement hermétiquement étanche grâce au joint torique situé à l'intérieur du collier. When the bypass tube is closed at the other end by a valve or other sealing means, the spatula is removed so that the pressure which invades the inside of the bypass tube pushes it outwards, making it prisoner of the flange which closes on it by the action of its conical surfaces, the assembly advantageously remaining hermetically sealed thanks to the O-ring located inside the collar.
Enfin, l'écrou est vissé à fond, ce qui fait descendre le tube jusqu'à la butée, et la bride se referme peu à peu, en serrant ainsi le tube plus fortement, ce qui termine 1' installation. Finally, the nut is fully screwed, which lowers the tube to the stop, and the flange gradually closes, tightening the tube more tightly, which ends 1 installation.
Cette installation permet que, à l'avenir, et si c'était nécessaire, on puisse utiliser ce collier comme valve d'arrêt en dévissant l'écrou suffisamment et en introduisant la spatule. This installation allows that, in the future, and if necessary, this collar can be used as a shut-off valve by loosening the nut sufficiently and inserting the spatula.

Le procédé de pose est le suivant
On fixe fermement le collier sur le conduit sur lequel on veut réaliser la dérivation (figure 1),
On retire du collier le joint torique 3, la rondelle 5, la bride 4 et l'écrou 6 et, en intercalant une pièce filetée d'assemblage 9, on pose sur le collier un outil 10 adéquat pour percer le conduit. Cet outil doit disposer des éléments d'étanchéité nécessaires pour que, après perçage du conduit, il n'y ait pas de fuites vers l'extérieur (figure 2).The installation process is as follows
We firmly fix the collar on the conduit on which we want to make the bypass (Figure 1),
The O-ring 3, the washer 5, the flange 4 and the nut 6 are removed from the collar, and, by inserting a threaded assembly piece 9, a suitable tool 10 is placed on the collar to pierce the conduit. This tool must have the necessary sealing elements so that, after drilling the conduit, there are no leaks to the outside (Figure 2).
Après perçage du conduit et retrait de l'outil de coupe 11, on introduit la spatule 12 qui glisse sur le joint multiple 1, ce qui permet de retirer l'outil de perçage 10 sans qu'il se produise de fuites (figure 3 et 4). After drilling the duct and removing the cutting tool 11, insert the spatula 12 which slides over the multiple joint 1, which allows the drilling tool 10 to be removed without leakage occurring (Figure 3 and 4).
On monte ensuite sur le collier les pièces retirées ci-dessus (joint torique 3, rondelle 5, bride 4 et écrou 6), en vissant l'écrou 6 jusqu'à ce qu'il touche la spatule 12 mais sans la serrer, et on introduit le tube de dérivation 13 jusqu'à ce qu'il bute sur une saillie intérieure 14 du collier 22 ou sur la spatule 12 elle-même (figure 5). The parts removed above are then mounted on the collar (O-ring 3, washer 5, flange 4 and nut 6), by screwing the nut 6 until it touches the spatula 12 but without tightening it, and the bypass tube 13 is introduced until it abuts on an internal projection 14 of the collar 22 or on the spatula 12 itself (FIG. 5).
Lorsque le tube 13 de dérivation est fermé à l'autre extrémité par une valve ou par un autre moyen d'obturation, on retire la spatule 12 et la pression qui s'établit à l'intérieur du tube 13 de dérivation le pousse vers l'extérieur, le rendant prisonnier de la bride 4 qui se referme sur lui par action de ses surfaces coniques respectives 4b, 6a, de sorte que l'ensemble reste hermétiquement étanche grâce au joint torique intérieur 2 (figure 6). When the bypass tube 13 is closed at the other end by a valve or by another closure means, the spatula 12 is removed and the pressure which builds up inside the bypass tube 13 pushes it towards the 'exterior, making it trapped in the flange 4 which closes on it by the action of its respective conical surfaces 4b, 6a, so that the assembly remains hermetically sealed thanks to the internal O-ring 2 (Figure 6).
On visse l'écrou à fond, ce qui fait descendre le tube jusqu'à la butée, et la bride se referme peu à peu, en serrant ainsi le tube plus fortement jusqu'à la fin de la pose (figure 7). The nut is screwed in fully, which lowers the tube to the stop, and the flange gradually closes, tightening the tube more tightly until the end of the installation (Figure 7).
Cette installation permet, à l'avenir, si c'était nécessaire, de pouvoir utiliser ce collier comme valve d'arrêt en dévissant l'écrou suffisamment et en introduisant la spatule. This installation allows, in the future, if necessary, to be able to use this collar as a stop valve by loosening the nut sufficiently and introducing the spatula.
Dans une réalisation préférée de l'invention, le collier se compose de deux demi-colliers fixés solidairement par des vis ou par d'autres moyens de fixation. Le demi-collier supérieur 24 comprend les éléments de dérivation décrits (figure 8). In a preferred embodiment of the invention, the collar consists of two half-collars fixed integrally by screws or by other fixing means. The upper half-collar 24 includes the bypass elements described (FIG. 8).
Dans un autre mode de réalisation, le collier est composé de deux pièces tout à fait différentes : une, supérieure, qui constitue une assise 15 disposant des moyens de dérivation, et une autre, inférieure, constituant une bride déformable 16, qui s'adapte au contour du conduit et fixe l'assise sur le conduit. In another embodiment, the collar is made up of two completely different parts: one, upper, which constitutes a seat 15 having bypass means, and another, lower, constituting a deformable flange 16, which adapts around the pipe and fixes the seat on the pipe.
L'assise et la bride sont solidarisées par des vis 17 ou par d'autres moyens de fixation (figure 9).The seat and the flange are secured by screws 17 or by other fixing means (Figure 9).
I1 est prévu un autre mode de réalisation dans lequel la partie supérieure du collier, soit en version demi-collier soit en version assise, se compose de deux pièces : une qui serait le demi-collier, ou assise, 18, et abriterait en son intérieur le joint torique, et l'autre pièce, constituant un corps 19, qui disposerait de tous les éléments de dérivation décrits ci-dessus. Entre ce corps et le joint multiple, on prévoit un système quelconque pour éviter qu'elle ne tourne, soit par frottement, soit avec une ailette de contre-rotation ou par un autre système (figure 10). De même, l'une des pièces composant le collier peut être recouverte d'un matériau isolant afin de prévenir la corrosion par couple galvanique. I1 is provided for another embodiment in which the upper part of the collar, either in the half-collar version or in the seated version, consists of two parts: one which would be the half-collar, or seat, 18, and would house its inside the O-ring, and the other part, constituting a body 19, which would have all the bypass elements described above. Between this body and the multiple joint, any system is provided to prevent it from rotating, either by friction, or with a counter-rotation fin or by another system (FIG. 10). Likewise, one of the parts making up the collar can be covered with an insulating material in order to prevent corrosion by galvanic torque.
Dans une variante de réalisation, le joint multiple est remplacé par deux joints indépendants : celui qui assure l'étanchéité avec le conduit 20 du réseau et celui qui assure l'étanchéité avec la spatule 21 et la fente (figure 11). In an alternative embodiment, the multiple seal is replaced by two independent seals: one that seals with the duct 20 of the network and one that seals with the spatula 21 and the slot (Figure 11).
Dans une autre variante de réalisation, l'écrou présente des ailettes 14 pour faciliter le serrage à la main ou avec une clef à crochet (figure 8). In another alternative embodiment, the nut has fins 14 to facilitate tightening by hand or with a hook wrench (Figure 8).
I1 est également à souligner une autre variante dans laquelle la bride ouverte est remplacée par une bride fermée 23 ou anneau, monté en usine sur un tube de dérivation qui peut être de la longueur requise (figure 12). I1 is also to emphasize another variant in which the open flange is replaced by a closed flange 23 or ring, factory fitted on a bypass tube which can be of the required length (Figure 12).
De même, le contour extérieur du collier permet de monter une version de la pièce d'assemblage 9, comprenant en son intérieur une fente 9a avec un joint torique 9b qui glisse sur la surface extérieure du collier 22a (figures 2 et 3). Likewise, the outer contour of the collar makes it possible to mount a version of the assembly part 9, comprising inside a slot 9a with an O-ring 9b which slides on the outer surface of the collar 22a (Figures 2 and 3).
Ceci permet que la pièce d'assemblage puisse être soulevée pour faire apparaître la fente 22b sans qu'il y ait de fuites. Ce système fait que, avantageusement, en réalisant le perçage du conduit, la partie supérieure du collier reste renforcée par l'assemblage qui, dans le cas contraire, serait affaiblie par la fente. This allows the assembly part to be lifted to reveal the slot 22b without any leaks. This system means that, advantageously, by drilling the conduit, the upper part of the collar remains reinforced by the assembly which, otherwise, would be weakened by the slot.
