Description

BACHE DE COMPTEUR DE FLUIDE , EN PARTICULIER D'EAU FLUID COUNTER PLATE, ESPECIALLY WATER
L'invention concerne une bâche de compteur de fluide, en particulier d'eau. Un compteur de fluide et en particulier d'eau est composé d'une bâche constituée d'un élément de réception d'un élément de mesure telle qu'une turbine par exemple et d'un totalisateur de comptage. Cet élément de réception est pourvu de deux tubulures filetées à leur extrémité, l'une d'entrée et l'autre de sortie du fluide, qui sont connectées à une conduite d'arrivée et à une conduite d'évacuation du fluide. Cette connexion est réalisée par une bague de serrage, par exemple en alliage cuivreux, venant buter contre une bride de la conduite et vissée sur la tubulure correspondante.The invention relates to a fluid meter cover, in particular water. A fluid meter and in particular water is composed of a sheet consisting of a receiving element of a measuring element such as a turbine for example and a counting totalizer. This receiving element is provided with two threaded connections at their end, one inlet and the other outlet fluid, which are connected to an inlet pipe and a fluid discharge pipe. This connection is made by a clamping ring, for example of cuprous alloy, abutting against a flange of the pipe and screwed on the corresponding pipe.
Un joint d'étanchéité est disposé entre la surface d'extrémité annulaire de la tubulure d'entrée ou de sortie de la bâche et la surface d'extrémité annulaire de la conduite d'arrivée ou d'évacuation correspondante. Le vissage de la bague de serrage sur la tubulure assure la compression du joint contre les deux surfaces d'extrémité et théoriquement l'étanchéité de la connexion. Un agencement de joint de ce type est décrit dans le document de brevet FR 2 865 585.A seal is disposed between the annular end surface of the inlet or outlet tubing of the sheet and the annular end surface of the corresponding inlet or outlet pipe. The tightening of the clamping ring on the tubing ensures the compression of the seal against the two end surfaces and theoretically the sealing of the connection. A seal arrangement of this type is described in patent document FR 2,865,585.
Compte tenu des intervalles de tolérance des différentes côtes et des écarts de forme ou de position des surfaces intervenant dans ce type d'étanchéité, le joint peut être déporté radialement lors de la mise en place de la connexion et dans un cas extrême venir en contact relativement limité sur une certaine zone, avec la surface d'extrémité de la tubulure ou des conduites. Ceci est préjudiciable, car peut entraîner une fuite de fluide à cet endroit.Given the tolerance intervals of the different ribs and the differences in shape or position of the surfaces involved in this type of sealing, the seal can be offset radially during the establishment of the connection and in an extreme case come into contact relatively limited over a certain area, with the end surface of the tubing or ducts. This is detrimental as it can cause fluid leakage at this location.
Dans le cadre des compteurs d'eau, de telles fuites représentent au moins 10% des bâches de compteurs installés. Or, une intervention sur un compteur ainsi défectueux est très chère relativement au prix d'un compteur, sans tenir compte des dégâts des eaux qui peuvent également en résulter.In the case of water meters, such leaks account for at least 10% of the meter covers installed. However, an intervention on a counter thus defective is very expensive relative to the price of a meter, without taking into account the water damage that can also result.
Par ailleurs, les pièces à manipuler pour le montage ou la réparation sont nombreuses, ce qui entraîne un stockage nécessaire de ces pièces et un temps de montage importantMoreover, the parts to be handled for assembly or repair are numerous, which entails a necessary storage of these parts and a long assembly time
La mise en place de ce joint n'est absolument pas maîtrisé. Lors de ce montage, le joint peut même être oublié et le compteur résultant totalement défectueux. Il se peut également qu'un opérateur mette en place un joint de matière et/ou de dimension non adaptées et qu'il en résulte une fuite, dans un certain laps de temps.The installation of this seal is absolutely not mastered. During this assembly, the seal can even be forgotten and the resulting counter totally defective. It is also possible for an operator to set up a seal of unsuitable material and / or dimension and to leak, within a certain period of time.
Pour résoudre ce problème, l'invention propose une bâche de compteur de fluide, équipée d'un agencement de joint d'étanchéité qui soit d'une fiabilité importante et maîtrisée, et dont le montage permette un gain de temps considérable. Pour ce faire, l'invention propose une bâche de compteur de fluide, équipée d'au moins un joint destiné à être disposé entre une surface d'extrémité annulaire d'une tubulure d'entrée ou de sortie de cette dernière et une surface d'extrémité annulaire d'une conduite d'arrivée ou d'évacuation du fluide, caractérisé en ce que ledit joint est solidaire de l'une des dites surfaces d'extrémité.To solve this problem, the invention provides a fluid meter cover, equipped with a seal arrangement which is of great reliability and control, and the mounting allows a considerable time saving. To do this, the invention proposes a fluid meter cover, equipped with at least one seal intended to be disposed between an annular end surface of an inlet or outlet pipe of the latter and a surface of annular end of a fluid inlet or outlet pipe, characterized in that said seal is integral with one of said end surfaces.
Selon un mode de réalisation préféré de l'invention, le joint est solidaire de ladite surface d'extrémité de ladite tubulure.According to a preferred embodiment of the invention, the seal is integral with said end surface of said tubing.
Le joint peut être partiellement encastré dans ladite surface d'extrémité. Le joint est de préférence surmoulé sur ladite surface d'extrémité.The seal may be partially embedded in said end surface. The seal is preferably overmolded on said end surface.
Avantageusement, la bâche est en matière plastique.Advantageously, the tarpaulin is made of plastic.
L'invention est décrite ci-après plus en détail à l'aide de figure ne représentant qu'un mode de réalisation préféré de l'invention.The invention is described below in more detail with the aid of a figure representing only a preferred embodiment of the invention.
La figure 1 est une vue en perspective d'un compteur de fluide conforme à l'invention.Figure 1 is a perspective view of a fluid meter according to the invention.
La figure 2 est une vue en perspective d'une bâche d'un compteur de fluide, conforme à l'invention. La figure 3 est une vue en coupe longitudinale de cette même bâche.Figure 2 is a perspective view of a sheet of a fluid meter according to the invention. Figure 3 is a longitudinal sectional view of the same tarpaulin.
La figure 4 est une vue de détail en coupe longitudinale de cette même bâche, connectée à une conduite d'alimentation ou d'évacuation de fluide. Comme visible sur les figures 1 à 3, un compteur de fluide, en particulier d'eau, est composé d'une bâche 1 constituée d'un élément de réception d'un élément de mesure telle qu'une turbine par exemple et d'un totalisateur de comptage 2. Cet élément de réception est pourvu de deux tubulures filetées à leur extrémité, l'une d'entrée 1 A et l'autre de sortie du fluide 1 B, qui sont destinées à être connectées à une conduite d'arrivée et à une conduite d'évacuation du fluide.Figure 4 is a detail view in longitudinal section of the same sheet, connected to a supply line or fluid discharge. As can be seen in FIGS. 1 to 3, a fluid meter, in particular of water, is composed of a tank 1 consisting of a receiving element of a measuring element such as a turbine for example and a counting counter 2. This receiving element is provided with two threaded connections at their end, one of inlet 1A and the other of fluid outlet 1B, which are intended to be connected to a pipe of arrival and a fluid evacuation pipe.
Un joint d'étanchéité J1 , J2 est destiné à être disposé entre la surface d'extrémité annulaire de la tubulure d'entrée 1A et/ou de la tubulure de sortie 1 B de la bâche 1 et une surface d'extrémité annulaire d'une conduite d'arrivée ou d'évacuation du fluide.A seal J1, J2 is intended to be disposed between the annular end surface of the inlet pipe 1A and / or the outlet pipe 1 B of the tank 1 and an annular end surface of a line of arrival or discharge of the fluid.
Ces joints, ici au nombre de deux, l'un J1 sur la tubulure d'entrée 1 A et l'autre J2 sur la tubulure de sortie 1 B, sont solidaires de la surface d'extrémité de la tubulure correspondante.These joints, here two in number, one J1 on the inlet pipe 1 A and the other J2 on the outlet pipe 1 B, are integral with the end surface of the corresponding pipe.
L'invention s'applique particulièrement à une bâche en matière plastique et les joints J1 et J2 sont surmoulés sur la surface d'extrémité de la tubulure correspondante.The invention is particularly applicable to a plastic sheet and J1 and J2 seals are overmolded on the end surface of the corresponding tube.
A titre d'exemple, une telle bâche 1 peut être réalisée en matière thermoplastique telle que les polyphtalamides (PPA), les polyphénylènes oxydes (PPO) ou les polysulfures de phénylène (PPS). Ces matières thermoplastiques peuvent être renforcées de fibre de verre ou d'autres adjuvants structurels ou thermiques.For example, such a tarpaulin 1 may be made of thermoplastic material such as polyphthalamides (PPA), polyphenylene oxides (PPO) or phenylene polysulfides (PPS). These thermoplastics may be reinforced with fiberglass or other structural or thermal additives.
Le joint surmoulé sur la bâche peut également être en matière thermoplastique par exemple en polyoxydeméthylène (POM), en acrylonitrile-butadiène-styrène (ABS), en polyamide (PA) ou en polyéthylène basse ou haute densité. De préférence, la matière pour le joint est moins dure que celle de la bâche. Cette souplesse relative permet au joint de mieux assurer I' étanchéité. Le joint peut également être injecté et être constitué de silicone ou d'élastomère tel que les EPDM ou les caoutchouc de nitrile butadiène.The seal overmolded on the sheet may also be thermoplastic material for example polyoxydemethylene (POM), acrylonitrile-butadiene-styrene (ABS), polyamide (PA) or low or high density polyethylene. Preferably, the material for the joint is less hard than that of the sheet. This relative flexibility allows the seal to better seal. The seal may also be injected and be made of silicone or elastomer such as EPDM or nitrile butadiene rubber.
La figure 4 représente la connexion d'une des tubulures, ici la tubulure de sortie 1 B de la bâche, avec une conduite 3 d'évacuation du fluide.FIG. 4 shows the connection of one of the pipes, here the outlet pipe 1 B of the tank, with a pipe 3 for evacuating the fluid.
Cette connexion est réalisée au moyen d'une bague de serrage 4, par exemple en alliage cuivreux, venant buter contre une bride 3A de la conduite et vissée sur la tubulure de sortie 1 B.This connection is made by means of a clamping ring 4, for example of cuprous alloy, abutting against a flange 3A of the pipe and screwed on the outlet pipe 1 B.
Le joint J2 est ici encastré partiellement dans la surface d'extrémité annulaire de la tubulure de sortie 1 B au moyen d'une bride B2 annulaire encastrée dans une rainure annulaire agencée sur la surface d'extrémité de la tubulure 1 B. Cet encastrement peut prendre la forme d'un anneau ou d'une couronne d'ergots cylindriques et régulièrement répartis sur la surface d'extrémité de la tubulure 1 B. La profondeur minimale de l'encastrement dépend de la liaison chimique qui peut avoir lieu entre les matériaux de la bâche 1 B et du joint J2. Cette liaison est d'autant plus forte que les compositions chimiques des deux matériaux sont proches. Plus cette liaison chimique et forte, plus la profondeur d'encastrement peut être faible voire nulle. Un encastrement profond permet de palier à une éventuelle faiblesse de la liaison chimique en assurant une liaison mécanique par adhérence.The seal J2 is here partially embedded in the annular end surface of the outlet pipe 1 B by means of an annular flange B2 embedded in an annular groove arranged on the end surface of the pipe 1 B. This installation can take the form of a ring or a ring of cylindrical lugs and evenly distributed on the end surface of the tubing 1 B. The minimum depth of the embedding depends on the chemical bond that can take place between the materials cover 1B and seal J2. This bond is all the stronger as the chemical compositions of the two materials are close. The stronger this chemical bond, the lower the embedment depth may be low or zero. A deep embedding makes it possible to overcome a possible weakness of the chemical bond by ensuring a mechanical connection by adhesion.
Bien que précédemment, il soit décrit un agencement où le joint est solidaire de la tubulure de la bâche, toujours dans le cadre de l'invention, il peut être utilisé un agencement où le joint est solidaire de la surface d'extrémité de la conduite d'alimentation ou d'évacuation, selon le même principe. Although previously, there is described an arrangement where the seal is integral with the tubing of the sheet, still within the scope of the invention, it can be used an arrangement where the seal is secured to the end surface of the pipe feeding or evacuation, according to the same principle.
