Abstract

The system consists of a plate (17) with two apertures (30) for the ends (16) of the flow pipe. The meter or a base (20) supporting the meter, are shaped to receive the two pipe ends and equipped with lugs (38) to fix it to the plate and seal rings (31). The pipe ends and base sockets to receive them are shaped so that the seal rings are located between the pipe ends and the base, and are compressed as fixings are tightened in the lugs. In addition, the plate and/or base have thrust surfaces (32) which are inclined relative to the axes of the seal rings to apply a radial pressure to them as they are compressed.

Description

La présente invention concerne des moyens permettant le montage d'un appareil traversé par un fluide dans une enveloppe de protection. L'invention est en particulier applicable à un compteur d'eau placé dans un regard enterré.The present invention relates to means for mounting an apparatus through which a fluid passes in a protective envelope. The invention is in particular applicable to a water meter placed in a buried manhole.

Les compteurs d'eau situés à l'extérieur d'un bâtiment sont logés dans des enveloppes assurant leur protection, notamment contre le gel. Ces enveloppes sont partiellement, dans le cas d'une borne, ou totalement, dans le cas d'un regard, enfouis dans le sol, de manière à atteindre les couches du sol restant en permanence à des températures positives. Le volume intérieur des enveloppes est ainsi maintenu à une température positive, par convection.The water meters located outside a building are housed in envelopes ensuring their protection, in particular against frost. These envelopes are partially, in the case of a terminal, or totally, in the case of a manhole, buried in the ground, so as to reach the layers of the ground remaining permanently at positive temperatures. The interior volume of the envelopes is thus maintained at a positive temperature, by convection.

Pour installer un compteur d'eau, il est connu de relier les extrémités de la conduite enterrée transportant l'eau à deux cannes tubulaires verticales destinées à supporter le compteur d'eau, puis de raccorder les extrémités du conduit traversant le compteur aux extrémités supérieures de ces deux cannes. Pour permettre ce raccordement, le compteur comprend deux tubulures inférieures taraudées, de diamètre interne supérieur au diamètre externe des cannes, et deux épaulements aménagés dans le fond de ces tubulures. Chaque canne reçoit un manchon fileté, dont le diamètre interne correspond, au jeu près, au diamètre externe de la canne. Chaque canne reçoit en outre, engagée sur son extrémité supérieure, une bague d'étanchéité en matériau compressible. La canne est ensuite introduite dans la tubulure correspondante du compteur d'eau jusqu'à venir, ainsi que la bague d'étanchéité qu'elle comporte, en appui contre l'épaulement se trouvant dans le fond de cette tubulure. Le manchon fileté est alors vissé dans la tubulure et vient serrer la bague d'étanchéité entre lui et cet épaulement. La déformation de la bague lors de ce serrage permet de réaliser le raccordement étanche du compteur à la canne.To install a water meter, it is known to connect the ends of the buried pipe carrying the water to two vertical tubular rods intended to support the water meter, then to connect the ends of the conduit passing through the meter to the upper ends. of these two rods. To allow this connection, the meter includes two tapped lower tubes, with an internal diameter greater than the external diameter of the rods, and two shoulders arranged in the bottom of these tubes. Each rod receives a threaded sleeve, the internal diameter of which corresponds, apart from the clearance, to the external diameter of the rod. Each rod also receives, engaged on its upper end, a sealing ring of compressible material. The rod is then introduced into the corresponding tubing of the water meter until it comes, as well as the sealing ring which it comprises, pressing against the shoulder located in the bottom of this tubing. The threaded sleeve is then screwed into the tubing and tightens the sealing ring between it and this shoulder. The deformation of the ring during this tightening allows the waterproof connection of the meter to the rod.

L'enveloppe de protection est ensuite engagée sur cet ensemble, puis le trou aménagé dans le sol pour recevoir cette enveloppe est comblé.The protective envelope is then engaged on this assembly, then the hole arranged in the ground to receive this envelope is filled.

Ce type de raccordement présente l'inconvénient très important d'être indémontable en cas d'apparition d'une fuite au niveau du raccordement des cannes et du compteur. En effet, les dimensions de l'enveloppe ne permettent pas d'accéder aux manchons filetés situés sous le compteur, en vue de leur démontage. Il en résulte qu'une telle fuite implique de creuser un large trou autour de l'enveloppe, pour pouvoir retirer cette enveloppe. Ces travaux sont longs et coûteux, peuvent être délicats lorsque le sol environnant est encombré, comme cela est le cas en site urbain, et impliquent généralement la destruction de l'enveloppe, qui doit ensuite être remplacée.This type of connection has the very significant drawback of being impossible to dismantle in the event of a leak appearing at the connection of the rods and the meter. Indeed, the dimensions of the envelope do not allow access to the threaded sleeves located under the meter, for disassembly. As a result, such a leak involves digging a large hole around the envelope, in order to be able to remove this envelope. These works are long and expensive, can be delicate when the surrounding soil is congested, as is the case in an urban site, and generally involve the destruction of the envelope, which must then be replaced.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

A cette fin, les moyens de montage qu'elle concerne comprennent :

  • une platine comprenant deux alésages aptes à recevoir les extrémités de la conduite transportant le fluide, ou les extrémités de deux cannes tubulaires raccordées à ces extrémités, et délimitant deux surfaces d'appui annulaires, coaxiales à ces alésages ;
  • un appareil, ou une embase supportant cet appareil, comprenant deux alésages aptes à recevoir les extrémités de la conduite ou des cannes tubulaires précitées, et délimitant deux surfaces d'appui annulaires, coaxiales à ces alésages, venant en regard des deux surfaces d'appui annulaires de la platine ;
  • des moyens à serrage permettant le montage amovible de l'appareil, ou de l'embase supportant cet appareil, sur la platine, ces moyens pouvant être manoeuvrés à partir de l'ouverture supérieure de l'enveloppe, et
  • deux bagues d'étanchéité placées entre les surfaces d'appui de la platine et de l'appareil ou embase, l'ensemble étant conformé de manière à ce que les surfaces d'appui de la platine et de l'appareil ou embase viennent serrer les bagues d'étanchéité entre elles lors du serrage des moyens de montage de l'appareil sur la platine.
To this end, the mounting means which it relates to include:
  • a plate comprising two bores capable of receiving the ends of the pipe transporting the fluid, or the ends of two tubular rods connected to these ends, and delimiting two annular bearing surfaces, coaxial with these bores;
  • an apparatus, or a base supporting this apparatus, comprising two bores capable of receiving the ends of the aforementioned pipe or canes, and delimiting two annular bearing surfaces, coaxial with these bores, coming opposite the two bearing surfaces plate annulars;
  • clamping means allowing the removable mounting of the device, or of the base supporting this device, on the plate, these means being able to be operated from the upper opening of the envelope, and
  • two sealing rings placed between the bearing surfaces of the plate and of the device or base, the assembly being shaped so that the bearing surfaces of the plate and of the device or base come to tighten the sealing rings between them when tightening the means of mounting the device on the plate.

Ainsi, il suffit de démonter l'appareil et de le retirer de la platine pour accéder aux bagues d'étanchéité et remédier à une éventuelle fuite survenant au niveau du raccordement à l'appareil des extrémités de la conduite ou des cannes tubulaires.Thus, it suffices to dismantle the device and remove it from the plate to access the sealing rings and remedy any leakage occurring at the level of the connection to the device of the ends of the pipe or of the tubular rods.

Avantageusement, les moyens de montage selon l'invention comprennent des moyens permettant la fixation de la platine à l'enveloppe, et l'appareil est monté sensiblement dans la partie centrale de la platine. La platine permet ainsi de maintenir l'appareil à distance des parois de l'enveloppe, afin que celui-ci reste parfaitement lisible depuis l'ouverture supérieure de l'enveloppe.Advantageously, the mounting means according to the invention comprise means allowing the fixing of the plate to the envelope, and the device is mounted substantially in the central part of the plate. The plate thus keeps the device at a distance from the walls of the envelope, so that it remains perfectly legible from the upper opening of the envelope.

Avantageusement, la platine et/ou l'appareil ou embase comprennent des surfaces d'appui inclinées par rapport à l'axe des bagues d'étanchéité, de manière à exercer sur ces bagues, lors du montage de l'appareil sur la platine, une force de serrage dont une composante est dirigée radialement vers l'intérieur de chaque bague. Les bagues serrent ainsi radialement les extrémités de la conduite ou des cannes, de sorte qu'une parfaite étanchéité est obtenue.Advantageously, the plate and / or the device or base comprise bearing surfaces inclined relative to the axis of the sealing rings, so as to exert on these rings, during the mounting of the device on the plate, a clamping force, a component of which is directed radially towards the inside of each ring. The rings thus tighten radially the ends of the pipe or rods, so that a perfect seal is obtained.

Selon une forme de réalisation préférée de l'invention :

  • la platine comprend deux alésages de diamètre correspondant, au jeu près, au diamètre extérieur des bagues d'étanchéité, et deux saillies annulaires aménagées dans la partie inférieure de ces alésages, dont chacune délimite une ouverture de dimension correspondant, au jeu près, au diamètre extérieur des extrémités de la conduite ou des cannes tubulaires précitées, les faces supérieures de ces saillies constituant les surfaces d'appui annulaires de la platine, et
  • l'appareil, ou une embase supportant cet appareil, comprend deux tubulures inférieures délimitant deux alésages de diamètre correspondant, au jeu près, au diamètre extérieur des extrémités de la conduite ou des cannes tubulaires précitées, et ayant un diamètre extérieur correspondant, au jeu près, au diamètre intérieur des alésages de la platine, les parois inférieures d'extrémité de ces tubulures constituant les surfaces d'appui annulaires de l'appareil.
According to a preferred embodiment of the invention:
  • the plate comprises two bores with a diameter corresponding, apart from the clearance, to the outside diameter of the sealing rings, and two annular projections arranged in the lower part of these bores, each of which delimits an opening of dimension corresponding, apart from play, to the outside diameter of the ends of the aforementioned pipe or tubular rods, the upper faces of these projections constituting the annular bearing surfaces of the plate, and
  • the device, or a base supporting this device, comprises two lower tubes delimiting two bores of diameter corresponding, to the clearance, to the outside diameter of the ends of the pipe or the aforementioned tubular rods, and having an outside diameter corresponding, to the clearance , to the internal diameter of the bores of the plate, the lower end walls of these pipes constituting the annular bearing surfaces of the device.

De préférence, l'enveloppe est constituée par une pluralité d'éléments assemblés les uns aux autres, notamment par emboîtement, dont l'un comprend une structure interne pour le montage de ladite platine. Ce montage de la platine dans l'enveloppe est ainsi réalisé de manière simple et rapide.Preferably, the envelope is constituted by a plurality of elements assembled to each other, in particular by interlocking, one of which comprises an internal structure for mounting said plate. This mounting of the plate in the envelope is thus carried out in a simple and rapid manner.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée d'un regard, destiné à être enterré et à abriter un compteur d'eau, comprenant les moyens de montage qu'elle concerne.

  • La figure 1 est une vue en perspective de ce regard, avec coupe longitudinale sur un secteur ;
  • la figure 2 est une vue en perspective éclatée de l'embase recevant le compteur, de deux cannes tubulaires raccordées à cette embase, de deux bagues assurant l'étanchéité de ce raccordement, et, avec coupe partielle, de la partie de ce regard supportant l'embase, et
  • la figure 3 est une vue de ces mêmes éléments après assemblage, en coupe selon la ligne III-III de la figure 1.
For a good understanding, the invention is again described below with reference to the appended schematic drawing representing, by way of nonlimiting example, a preferred embodiment of a manhole, intended to be buried and to house a counter of water, comprising the mounting means which it relates to.
  • Figure 1 is a perspective view of this look, with longitudinal section on a sector;
  • Figure 2 is an exploded perspective view of the base receiving the meter, of two tubular rods connected to this base, of two rings ensuring the tightness of this connection, and, with partial section, of the part of this manhole supporting the base, and
  • FIG. 3 is a view of these same elements after assembly, in section along line III-III of FIG. 1.

La figure 1 représente un regard 1 destiné à être enterré dans le sol, assurant la protection d'un compteur d'eau (non représenté), notamment contre le gel.Figure 1 shows a manhole 1 intended to be buried in the ground, ensuring the protection of a water meter (not shown), in particular against frost.

Le regard 1 est constitué par une pluralité d'éléments assemblés les uns aux autres par emboîtement, à savoir :

  • trois éléments tubulaires 5, permettant de former le conduit du regard 1,
  • un élément tubulaire 7 supportant le compteur,
  • une coque 8, engagée par coulissement sur les éléments 5 et 7, permettant de délimiter avec ceux-ci un espace annulaire fermé dans lequel peut être injecté un matériau d'isolation thermique auto-expansible, tel qu'une mousse de polyuréthanne,
  • un élément 9 formant un piètement destiné à venir en appui contre le fond du trou aménagé pour recevoir le regard 1, et
  • un élément supérieur 10 de fermeture du regard 1, engagé dans le dernier élément 5, comportant une bride 11 destinée à affleurer avec le sol et une trappe amovible 12.
The manhole 1 is constituted by a plurality of elements assembled to each other by interlocking, namely:
  • three tubular elements 5, used to form the manhole conduit 1,
  • a tubular element 7 supporting the counter,
  • a shell 8, engaged by sliding on the elements 5 and 7, making it possible to delimit with them a closed annular space into which a self-expanding thermal insulation material, such as a polyurethane foam, can be injected,
  • an element 9 forming a base intended to come into abutment against the bottom of the hole arranged to receive manhole 1, and
  • an upper element 10 for closing the manhole 1, engaged in the last element 5, comprising a flange 11 intended to be flush with the ground and a removable hatch 12.

Ainsi que le montre la figure 1, l'élément 9 comprend deux raccords 15 coudés à 90°, montés, au moyen d'écrous vissés, au travers de deux ouvertures aménagées à l'opposé l'une de l'autre dans l'élément 9. Chacun de ces raccords 15 est relié, d'une part, à la conduite enterrée (non représentée) transportant l'eau, et d'autre part, à une canne tubulaire verticale 16. L'extrémité supérieure de chaque canne 16 est engagée au travers d'une platine 17 et est raccordée de manière étanche à une extrémité d'un conduit 18 aménagé au travers d'une embase 20, cette embase 20 étant destinée à supporter le compteur.As shown in FIG. 1, the element 9 comprises two connectors 15 bent at 90 °, mounted, by means of screwed nuts, through two openings arranged opposite one another in the element 9. Each of these fittings 15 is connected, on the one hand, to the buried pipe (not shown) transporting the water, and on the other hand, to a vertical tubular cane 16. The upper end of each cane 16 is engaged through a plate 17 and is sealingly connected to one end of a conduit 18 arranged through a base 20, this base 20 being intended to support the meter.

La platine 17 présente sensiblement une forme de T et est montée, ainsi que cela est plus particulièrement visible aux figures 2 et 3, sur une structure interne 25 que comprend l'élément 7. Cette platine 17 comprend, à cet effet, des trous 27 au niveau des extrémités de ses branches, et la structure 25 comprend des trous taraudés correspondants, dans lesquels sont engagées des vis (non représentées).The plate 17 has substantially a T shape and is mounted, as is more particularly visible in Figures 2 and 3, on an internal structure 25 that comprises the element 7. This plate 17 comprises, at this indeed, holes 27 at the ends of its branches, and the structure 25 comprises corresponding tapped holes, in which are engaged screws (not shown).

La platine 17 comprend également deux alésages 30 de diamètre correspondant, au jeu près, au diamètre extérieur de bagues 31 assurant l'étanchéité du raccordement des cannes 16 à l'embase 20, et deux saillies annulaires 32 aménagées dans la partie inférieure de ces alésages 30. Chacune de ces saillies 32 délimite une ouverture de dimension correspondant, au jeu près, au diamètre extérieur des cannes 16, et présente une face supérieure inclinée en direction de la face inférieure de la platine 17.The plate 17 also includes two bores 30 of diameter corresponding, apart from play, to the outside diameter of rings 31 ensuring the tightness of the connection of the rods 16 to the base 20, and two annular projections 32 arranged in the lower part of these bores 30. Each of these projections 32 defines an opening of dimension corresponding, apart from play, to the outside diameter of the rods 16, and has an upper face inclined in the direction of the lower face of the plate 17.

L'embase 20 comprend, quant à elle, sur le conduit 18, un siège 35 servant au montage du compteur d'eau et un robinet d'arrêt 36 muni d'un carré de manoeuvre 37.The base 20 comprises, for its part, on the duct 18, a seat 35 used for mounting the water meter and a stop valve 36 provided with an operating square 37.

Elle comprend également trois pattes 38 en saillie, percées de trous 39 qui viennent en correspondance de trous taraudés 40 aménagés dans la platine 17. Ces trous 39 et 40 sont destinés à recevoir des vis 41, dont une est représentée à la figure 3, permettant le montage et le serrage de l'embase 20 sur la platine 17.It also includes three projecting tabs 38, pierced with holes 39 which correspond to tapped holes 40 arranged in the plate 17. These holes 39 and 40 are intended to receive screws 41, one of which is shown in Figure 3, allowing mounting and tightening the base 20 on the plate 17.

L'embase 20 comprend en outre deux tubulures inférieures 45, délimitant deux alésages 46 de diamètre correspondant, au jeu près, au diamètre extérieur des cannes 16, et ayant un diamètre extérieur correspondant, au jeu près, au diamètre intérieur des alésages 30.The base 20 further comprises two lower tubes 45 delimiting two bores 46 of diameter corresponding, apart from play, to the outside diameter of the rods 16, and having an outside diameter corresponding, apart from play, to the inside diameter of bores 30.

En pratique, lors de la constitution du regard 1 par assemblage des éléments 5 à 10, les cannes tubulaires 16 sont coupées à longueur adéquate pour être engagées au travers des alésages 30, et faire légèrement saillie au-delà de ceux-ci, comme cela est montré à la figure 2. Les bagues d'étanchéité 31 sont alors engagées dans les alésages 30, puis l'embase 20 est montée sur la platine 17, avec engagement de ses tubulures 45 dans les alésages 30.In practice, when building the manhole 1 by assembling the elements 5 to 10, the tubular rods 16 are cut to an adequate length to be engaged through the bores 30, and protrude slightly beyond them, like this is shown in Figure 2. The sealing rings 31 are then engaged in the bores 30, then the base 20 is mounted on the plate 17, with engagement of its pipes 45 in the bores 30.

La platine 17, les alésages 30, les saillies annulaires 32, les bagues 31, les pattes 38, les tubulures 45 et les vis 41 sont conformés de manière telle que, lors du serrage des vis 41, les parois inférieures d'extrémité 47 des tubulures 45 viennent en appui contre les bagues 31, et les serrent entre elles et les saillies annulaires 32.The plate 17, the bores 30, the annular projections 32, the rings 31, the lugs 38, the pipes 45 and the screws 41 are shaped so that, when the screws 41 are tightened, the lower end walls 47 of the pipes 45 come to bear against the rings 31, and clamp them between them and the annular projections 32.

L'inclinaison des faces supérieures de ces saillies 32 permet d'exercer sur les bagues 31 une force de serrage dont une composante est dirigée radialement vers l'intérieur. Les bagues 31 serrent ainsi radialement les extrémités des cannes 16, de sorte qu'une parfaite étanchéité est obtenue.The inclination of the upper faces of these projections 32 makes it possible to exert a clamping force on the rings 31, a component of which is directed radially inwards. The rings 31 thus tighten radially the ends of the rods 16, so that a perfect seal is obtained.

L'embase 20 peut être démontée de la platine 17, à partir de l'ouverture supérieure du regard 1, par desserrage et retrait des vis 41. Il est ainsi possible d'accéder aux bagues d'étanchéité 31, afin de remédier à une éventuelle fuite survenant entre l'embase 20 et les cannes 16.The base 20 can be removed from the plate 17, from the upper opening of the manhole 1, by loosening and removing the screws 41. It is thus possible to access the sealing rings 31, in order to remedy a possible leakage occurring between the base 20 and the rods 16.

En outre, l'élément 7 et la platine 17 permettent de maintenir le compteur à distance des parois du regard 1, de sorte que ce compteur reste parfaitement lisible depuis l'ouverture supérieure du regard 1.In addition, the element 7 and the plate 17 make it possible to keep the counter away from the walls of the manhole 1, so that this counter remains perfectly readable from the upper opening of manhole 1.
