Description

Robinet à bague d'étanchéité revêtue d'un agent de démoulage  Sealing ring valve coated with a release agent
Les robinets à papillon de grand diamètre, dont, par exemple, le diamètre intérieur est de un mètre et plus, sont généralement constitués d'un corps annulaire garni intérieurement d'une bague d'étanchéité en matériau élastique, sur laquelle, à la fermeture du 'robinet, le papillon en forme de disque vient porter de façon étanche . Butterfly valves of large diameter, of which, for example, the inner diameter is one meter and more, generally consist of an annular body lined internally with a sealing ring of elastic material, on which, at the closure the faucet, the disc-shaped butterfly comes to bear tightly.
Afin de résister aux efforts de fermeture du papillon et des contraintes du fluide véhiculé, ' ces bagues d'étanchéité sont généralement pourvues de tenons, qui se logent dans le corps du robinet dans des rainures aux formes complémentaires. To resist throttle closure stresses and strains of the conveyed fluid, 'these sealing rings are generally provided with pins, which fit in the valve body in grooves of complementary forms.
Le corps de ces robinets étant métallique, pour résister aux efforts de pression à l'intérieur de la tuyauterie, les usinages sont souvent compliqués et onéreux à réaliser . The body of these valves being metallic, to withstand the pressure forces inside the piping, the machining is often complicated and expensive to achieve.
Si ces formes sont simples, l'accrochage de la bague est aléatoire, -voire insuffisant, et, si ces formes sont très étudiées, elles sont difficiles à réaliser pour d'aussi grandes pièces et le montage est impossible ou, tout au moins, très difficile. (voir le brevet français 2 820 184) . If these forms are simple, the attachment of the ring is random, -voire insufficient, and, if these forms are very studied, they are difficult to achieve for such large parts and editing is impossible or, at least, very difficult. (see French Patent 2,820,184).
Pour résoudre ce problème, certains constructeurs ont inventé des solutions de collage ou de moulage de matière polymère, qui permettent de fixer de manière indémontable la bague dans le corps du robinet (voir le brevet français FR2260041). Dans des solutions de bagues collées, le corps est usiné suivant un- profil correspondant exactement au profil de la bague d ' étanchéité, tandis qu'un film de colle assure l'adhérence de cette bague sur le corps. To solve this problem, some manufacturers have invented bonding solutions or molding of polymeric material, which can releasably fix the ring in the body of the valve (see French patent FR2260041). In bonded ring solutions, the body is machined in a profile exactly corresponding to the profile of the sealing ring, while a film of adhesive ensures the adhesion of this ring to the body.
Dans la solution moulée, des gorges de formes complexes sont réalisées dans le corps, tandis que la bague d1 étanchéité en élastomère est pourvue de tenons annulaires de formes non complémentaires à celles des gorges du corps. Dans l'espace libre laissé par ces formes non complémentaires, est déposée une résine polymère, qui, en durcissant, réalisera une clé de verrouillage solide, qui vient solidariser la bague d' étanchéité sur le corps. Cette configuration rend la bague d' étanchéité indémontable. In the molded solution, complex shapes of grooves are formed in the body, while the ring one elastomeric seal is provided with annular lugs non-complementary shapes to those of the grooves of the body. In the free space left by these non-complementary forms, a polymer resin is deposited which, when hardening, will produce a solid locking key, which joins the sealing ring to the body. This configuration makes the sealing ring indestructible.
Ces solutions sont techniquement imparfaites et leurs inconvénients sont les suivants : These solutions are technically imperfect and their disadvantages are:
- Les usinages des gorges sont techniquement difficiles et compliqués à réaliser sur le corps d'un robinet de grand diamètre, qui peut faire de un à plusieurs mètres de diamètre et peser plusieurs tonnes. - Machining gorges are technically difficult and complicated to achieve on the body of a large diameter valve, which can be one to several meters in diameter and weigh several tons.
- Le remplissage des gorges réalisées dans le corps, lors de la mise en place de la bague d' étanchéité, est toujours imparfait, en raison de la fluidité de la résine et du manque de dégagement de l'air emprisonné entre corps et bague. - The filling of the grooves made in the body, during the establishment of the sealing ring, is always imperfect, because of the fluidity of the resin and the lack of release of air trapped between the body and ring.
- La bague d' étanchéité n'est pas interchangeable. En cas d'accident de montage, ou bien d'usure ou de détérioration de la bague, le robinet doit être démonté de sa tuyauterie, retourné en usine et reconditionné en atelier, pour arracher et détruire la bague endommagée, enlever mécaniquement la résine polymérisée dans les gorges du corps, changer et recoller la bague neuve. - The sealing ring is not interchangeable. In the event of a mounting accident, or wear or damage to the ring, the valve must be removed from its piping, returned to the factory and reconditioned in the workshop, to tear and destroy the damaged ring, mechanically remove the resin polymerized in the grooves of the body, change and reassemble the new ring.
L'invention pallie ces inconvénients par un robinet à papillon de grand diamètre, par exemple supérieur à un mètre de diamètre, qui ne nécessite pas un usinage de gorges difficile à réaliser sur le corps du robinet et dont on peut changer facilement la bague d' étanchéité, lorsqu'elle est usée, pour la remplacer par une neuve, sans avoir à retourner le robinet en usine. L'invention a pour objet un robinet comprenant un corps annulaire ayant une gorge sur chaque face latérale, deux passages radiaux d'arbre diamétralement opposés, de la résine en contact et adhérisée avec la face intérieure du corps, une bague d' étanchéité en contact avec la face intérieure de la résine et ayant des crampons sur la face extérieure et, pénétrant dans les gorges, des tenons sur les deux faces latérales et un papillon monté tournant en venant, en une position de fermeture du robinet, porter contre la face intérieure de la bague et s'en éloignant en une position de fermeture du robinet, caractérisé en ce que le corps a au moins deux trous radiaux traversants de section transversale plus petite que celles des passages, la face intérieure de la résine a des rainures de forme conjuguée de celle des crampons et la face extérieure de la bague est revêtue d'un film d'agent de démoulage. The invention overcomes these disadvantages by a butterfly valve of large diameter, for example greater than one meter in diameter, which does not require machining grooves difficult to achieve on the valve body and which can easily change the ring of sealing, when worn, to replace it with a new one, without having to return the valve at the factory. The invention relates to a valve comprising an annular body having a groove on each side face, two diametrically opposite radial shaft passages, the resin in contact and adhered with the inner face of the body, a sealing ring in contact with the inner face of the resin and having crampons on the outer face and, penetrating the grooves, tenons on the two lateral faces and a butterfly mounted rotating while coming, in a closed position of the valve, to bear against the inner face of the ring and moving away in a closed position of the valve, characterized in that the body has at least two radial through holes of smaller cross section than those of the passages, the inner face of the resin has shape grooves conjugated with that of the crampons and the outer face of the ring is coated with a release agent film.
La bague est en un matériau élastique de type plastomère ou élastomère. The ring is made of an elastic material of the plastomer or elastomer type.
Suivant l'invention, c'est dans la résine elle-même que sont ménagées les formes conjuguées des crampons de la bague et la bague elle-même est revêtue d'un agent de démoulage, de sorte qu'après polymérisation de ' la résine, la bague peut être désencliquetée des formes conjuguées des crampons. Pour remplacer la bague, il suffit de la détacher de la résine. En outre, comme les rainures de forme conjuguée de la résine sont obtenues par coulée directe de la résine sur les crampons, il n'est pas nécessaire de prévoir un usinage, pour assurer 1 ' encliquetage des crampons dans leurs formes conjuguées. According to the invention, it is in the resin itself that the conjugate forms of the crampons of the ring are formed and the ring itself is coated with a coating agent. demolding, so that, after polymerization of 'the resin, the ring can be disengaged conjugated forms spikes. To replace the ring, simply detach it from the resin. In addition, as the conjugate-shaped grooves of the resin are obtained by direct casting of the resin on the crampons, it is not necessary to provide a machining, to ensure 1 latching cleats in their conjugate forms.
Les passages d'arbre sont destinés au passage de l'arbre de manœuvre du papillon et., de l'axe intérieur sur lequel le papillon tourillonne, '.ils sont de section droite circulaire- en ayant un diamètre compris, pour des robinets de grande dimension, entre 0,12.5 fois et 0,07 fois le diamètre du papillon en fonction du matériau de l'axe et de la pression à étancher. Les trous radiaux traversant le corps sont destinés à permettre d'injecter de la résine. Ils sont, de préférence, eux aussi de section droite circulaire mais pourraient ne pas l'être. Leur diamètre est plus petit, notamment égal au 1/4 du diamètre de l'arbre et de l'axe inférieur. De préférence, ces trous d'injection sont disposés symétriquement par rapport aux passages d'arbre. On préfère prévoir quatre trous diamétralement opposés, une paire de trous étant disposés de manière symétrique par rapport à un passage. Les trous restent remplis de résine après que celle-ci a durci. The shaft passages are for the passage of the throttle valve operating shaft and., The inner shaft on which the butterfly journalled '.ils are circularly right section having a diameter including, for faucets large dimension, between 0.12.5 times and 0.07 times the diameter of the throttle depending on the material of the axis and the pressure to be sealed. The radial holes through the body are intended to allow the injection of resin. They are preferably also of circular cross section but may not be. Their diameter is smaller, especially equal to 1/4 of the diameter of the shaft and the lower axis. Preferably, these injection holes are arranged symmetrically with respect to the shaft passages. It is preferred to provide four diametrically opposed holes, a pair of holes being arranged symmetrically with respect to a passage. The holes remain filled with resin after it has hardened.
De préférence, l'agent de démoulage pour élastomère est un film, de 1 à 20 microns d'épaisseur, d'un composé, dont les propriétés physico-chimiques interdisent l'adhérence entre l' élastomère et tout autre corps. Cet agent est constitué principalement d'un composant actif et d'un solvant. Le composant actif, choisi pour ses propriétés anti-adhésives , peut être, notamment : Preferably, the release agent for elastomer is a film, 1 to 20 microns thick, of a compound whose physicochemical properties prohibit adhesion between the elastomer and any other body. This agent consists mainly of an active component and a solvent. The active component, chosen for its anti-adhesive properties, can be, in particular:
• du mica, formé de silicate d'aluminium et de potassium,  • mica, formed of aluminum and potassium silicate,
• du polytétrafluoroéthylène (PTFE) ,  • polytetrafluoroethylene (PTFE),
• du silicone ou ' polysiloxane, qui est un composé organique formé d'une chaîne silicium-oxygène .  Silicone or polysiloxane, which is an organic compound formed of a silicon-oxygen chain.
Le solvant peut être de forme aqueuse ou hydrocarbonée. L'agent de démoulage peut être : The solvent may be of aqueous or hydrocarbon form. The release agent can be:
• soit pâteux, il ést alors déposé par enduction au pinceau ou à la brosse,  • is pasty, it is then deposited by coating with a brush or a brush,
• soit liquide, il est alors déposé par trempage, par enduction . au pinceau ou à la brosse ou bien par pulvérisation mécanique ou oléopneumatique . • is liquid, it is then deposited by dipping, by coating . by brush or brush or by mechanical or oleopneumatic spraying.
Le processus du dépôt de l'agent de démoulage consiste, après enduction de la pièce à traiter, à attendre 1 ' évaporation du solvant. Le solvant étant évaporé, la pièce est prête pour l'utilisation. La bague se désenclxquette d'autant plus facilement de la résine qu'un crampon est en forme de champignon ayant une tige issue de la base de la bague et une tête surmontant la tige. La tête ne fait saillie latéralement de la tige que d'un côté et, en section suivant un plan diamétral passant par l'axe du corps, la face de la saillie tournée vers la face de la bague lui est sensiblement parallèle. Cette base définit la partie la plus large du crampon. Pour bien assurer la possibilité de désencliquetage, et donc de remplacement de la bague, en section suivant un plan diamétral passant par l'axe du corps, la largeur de la saillie représente de 1/5 à 1/3 de la largeur de la tête et la hauteur de la tête est à peu près égale à la hauteur de la tige. De préférence, la tige a des chanfreins supérieurs faisant un angle de 30° à 45° avec la direction de la tige en hauteur. Les saillies d'une demi bague sont, vues dans le plan diamétral passant par l'axe du corps, toutes dirigées dans le même sens. The process of depositing the release agent consists, after coating the workpiece, to wait for evaporation of the solvent. The solvent is evaporated, the room is ready for use. The ring désenclxquette all the more easily resin that a spike is mushroom-shaped having a stem from the base of the ring and a head surmounting the stem. The head protrudes laterally from the rod only on one side and, in section along a diametral plane passing through the axis of the body, the face of the projection facing the face of the ring is substantially parallel thereto. This base defines the widest part of the crampon. To ensure the possibility of disengaging, and therefore replacement of the ring, in section following a diametral plane passing through the axis of the body, the width of the projection is 1/5 to 1/3 of the width of the head and the height of the head is approximately equal to the height of the rod. Preferably, the stem has upper chamfers at an angle of 30 ° to 45 ° with the direction of the upper stem. The projections of a half ring are seen in the diametral plane passing through the axis of the body, all directed in the same direction.
De préférence, la face de la saillie tournée vers la base de la bagué fait ..un angle droit de plus ou moins 15° avec la face latéralë. de l'âme principale du crampon ou base de la bague, soit un angle compris entre 105° et 75°. Si cette condition n'est pas respectée, le crampon deviendrait difficile à démonter en cas d'un angle plus aigu, inférieur à 75°, tandis que dans le cas d'un angle plus obtus, supérieur à 105°, la fonction de blocage du crampon dans sa gorge ne serait plus assurée et la bague risquerait de se déchausser sous l'effet des sollicitations dues à la vitesse du fluide. Preferably, the face of the projection facing the base of the band is at a right angle of plus or minus 15 ° with the side face. the main core of the crampon or base of the ring, an angle between 105 ° and 75 °. If this condition is not respected, the crampon would become difficult to disassemble at a higher angle, less than 75 °, while in the case of a more obtuse angle, greater than 105 °, the locking function a crampon in his throat would no longer be insured and the ring could loosen under the effect of the stresses due to the speed of the fluid.
On fabrique un robinet suivant l'invention en se procurant un corps de robinet suivant l'invention, en mettant les deux tenons latéraux d'une bague d'étanchéité dans les gorges, la bague ayant des crampons sur la face extérieure et une couche d'agent de démoulage sur la face extérieure, en injectant de la résine par les trous dans l'espace compris entre le corps et la bague, de manière à remplir cet espace et en laissant durcir la résine. Aux dessins annexés, données uniquement à titre d'exemple : A faucet according to the invention is manufactured by obtaining a valve body according to the invention, by putting the two lateral lugs of a sealing ring into the grooves, the ring having cleats on the outer face and a layer of release agent on the outer face, by injecting resin through the holes in the space between the body and the ring, so as to fill this space and allowing the resin to harden.

1 ' invention . The invention.
Le robinet suivant l'invention comprend un corps 1 annulaire métallique, dont le diamètre intérieur est cylindrique uni et les faces latérales équipées de gorges 2 sans aucun autre usinage et une bague d'étanchéité 3, qui enserre le corps 1. Cette bague d'étanchéité 3 est pourvue sur sa surface extérieure de crampons 4 en forme de harpon. The valve according to the invention comprises a metal annular body 1, whose inner diameter is cylindrical and the side faces equipped with grooves 2 without any other machining and a sealing ring 3, which encloses the body 1. This ring of Sealing 3 is provided on its outer surface spikes 4 spear-shaped.
Les deux faces latérales de cette bague d'étanchéité 3 sont équipées chacune d'un tenon latéral 5, dont la forme est étudiée de manière à assurer l'étanchéité entre les brides de la tuyauterie et le corps 1 du robinet, grâce aux formes complémentaires des gorges 2 du corps. The two lateral faces of this sealing ring 3 are each equipped with a lateral tenon 5, the shape of which is designed so as to ensure the seal between the flanges of the pipework and the body 1 of the tap, thanks to the complementary shapes gorges 2 of the body.
L'espace libre entre le corps 1 et la bague 3 est comblé par une matière composite 6 constituée d'une charge minérale ou de fibres et de résine polymère. Ce compound 6 est injecté entre le corps 1 et la bague d'étanchéité 3 au moyen de quatre trous 7 d'injection pratiqués dans le corps 1. Ces trous d'injection sont symétriquement disposés par rapport à des passages 8 d'arbre, dont l'un est placé à la partie supérieure près de l'arbre de manœuvre et le second près de l'axe inférieur. En s 'appliquant sur les crampons 4, la résine forme. 'des rainures 13 de forme conjuguée de celle des crampons 4. The free space between the body 1 and the ring 3 is filled by a composite material 6 consisting of a load mineral or fiber and polymer resin. This compound 6 is injected between the body 1 and the sealing ring 3 by means of four injection holes 7 made in the body 1. These injection holes are symmetrically arranged with respect to shaft passages 8, of which one is placed at the top near the maneuvering shaft and the second near the lower axis. By applying on the crampons 4, the resin forms. 'Of the grooves 13 of shape matching that of the spikes 4.
De manière à ce que le compound 6 n'adhère pas à la bague d'étanchéité 3, la face extérieure de la bague, qui porte les crampons 4, est enduite d'un film 9 d'un agent de démoulage formulé pour les élastomères. Un papillon 10, portant sur la bague 3 en position de fermeture du robinet et à distance de celle-ci en position d'ouverture, est solidaire en rotation d'un arbre passant dans l'un des passages 8. So that the compound 6 does not adhere to the sealing ring 3, the outer face of the ring, which carries the crampons 4, is coated with a film 9 of a release agent formulated for the elastomers . A butterfly 10, bearing on the ring 3 in the closed position of the valve and at a distance from the latter in the open position, is integral in rotation with a shaft passing through one of the passages 8.
Les crampons 4 de la bague 3, placés sur la face cylindrique extérieure 11, ont une forme de harpon ou de demi-T en champignon, dont au moins une- face 12 de la tête 17, est parallèle à la face cylindrique 11 de la bague d'étanchéité. Cette face 12 fait un angle droit de plus ou moins quinze degrés avec la face latérale de la tige principale du crampon suivant un angle compris entre 105° et 75°. The crampons 4 of the ring 3, placed on the outer cylindrical face 11, have a harpoon or half-T mushroom shape, of which at least one face 12 of the head 17 is parallel to the cylindrical face 11 of the watertight ring. This face 12 is at a right angle of plus or minus fifteen degrees with the side face of the main stem of the crampon at an angle between 105 ° and 75 °.
Comme montré à la Figure 4, la valeur de la largeur Ll de cette face 12 est comprise entre 1/5 et 1/3 de la valeur de la largeur L2 de la base du crampon, afin d'assurer un bon accrochage de la bague d'étanchéité 3 dans le composite 8, tandis que la hauteur H4 de cette face 12 est sensiblement égale à la moitié de la valeur de la hauteur totale H3 du crampon. Les chanfreins 16 et 16', dont l'angle est compris entre 45° et 30°, sont définis pour permettre le parfait démontage et remontage du crampon dans sa rainure 13 résultant de l'injection et de la polymérisation de la résine sur les crampons 4. As shown in FIG. 4, the value of the width L 1 of this face 12 is between 1/5 and 1/3 of the value of the width L 2 of the crampon base, in order to ensure a good engagement of the ring 3 in the composite 8, while the height H4 of this face 12 is substantially equal to half the value of the total height H3 of the crampon. The chamfers 16 and 16 ', whose angle is between 45 ° and 30 °, are defined to allow the perfect disassembly and reassembly of the crampon in its groove 13 resulting from the injection and the polymerization of the resin on the crampons 4.
Suivant un mode de construction montré à la Figure 5, les crampons de la bague 3, c'est-à-dire leur barre du té, peuvent être- orientés tous dans le même sens. En décrochant l'un des tenons ou les deux, on désencliquette facilement les crampons. According to a mode of construction shown in Figure 5, the crampons of the ring 3, that is to say their bar of the tee, can be all oriented in the same direction. By unhooking one or both tenons, you easily unclog the crampons.
Suivant d'autres modes de construction, comme montré à la Figure 3 les tenons d'une demi bague sont orientés dans un sens et ceux de l'autre demi bague dans le sens opposé. On désencliquette la bague en décrochant symétriquement les deux tenons 7 des gorges 2. According to other modes of construction, as shown in Figure 3 the tenons of a half ring are oriented in one direction and those of the other half ring in the opposite direction. Disengage the ring by unhooking symmetrically the two tenons 7 grooves 2.
