La présente invention concerne un système de joint d'étanchéité pour raccords et en particulier pour des raccords rapides qui sont utilisés périodiquement pour des opérations de vidange de cuves ou citernes. The present invention relates to a seal system for fittings and in particular for quick couplings which are used periodically for emptying operations of tanks or tanks.
Ainsi par exemple, dans le domaine du ramassage du lait dans les fermes, l'opérateur chargé de la collecte est amené à relier la citerne de son véhicule à la cuve ou tank du producteur, au moyen d'un conduit souple de transfert muni d'un raccord rapide qui coopère avec un embout de raccord disposé sur le tank à lait, pour réaliser la vidange. For example, in the field of collecting milk on farms, the operator in charge of collection is required to connect the tank of his vehicle to the tank or tank of the producer, by means of a flexible transfer conduit equipped with a quick coupling which cooperates with a coupling end arranged on the milk tank, to carry out the emptying.
Selon leur capacité, ces tanks à lait sont aménagés pour être vidangés tous les deux ou trois jours. Depending on their capacity, these milk tanks are arranged to be emptied every two or three days.
L'opérateur chargé de la collecte du lait effectue plusieurs dizaines de raccordements par jour entre sa citerne et les différents tanks à lait de son circuit. The operator in charge of the collection of milk makes dozens of connections per day between his tank and the various milk tanks of his circuit.
Pour obtenir une bonne étanchéité au niveau du raccord, un joint est prévu et, bien souvent, ce joint est disposé sur le raccord rapide du conduit attaché à la citerne du véhicule de collecte. To obtain a good seal at the connection, a seal is provided and, very often, this seal is disposed on the quick coupling of the conduit attached to the tank of the collection vehicle.
On observe une dégradation rapide de ce raccord compte-tenu du nombre de manipulations effectuées dans une journée. There is a rapid deterioration of this connection given the number of manipulations performed in a day.
De plus, pour maintenir un état d'hygiène compatible avec le produit collecté, il est nécessaire de prévoir un joint démontable de façon à pouvoir nettoyer ce joint ainsi que l'emplacement où il se situe au niveau du raccord. In addition, to maintain a hygienic state compatible with the collected product, it is necessary to provide a removable seal so as to clean the seal and the location where it is located at the connection.
Ce joint doit être démontable facilement et cette contrainte a aussi pour conséquence de faciliter la perte du joint qui, après plusieurs utilisations et démontages, a tendance à s'échapper de son logement. This seal must be easily dismountable and this constraint also has the effect of facilitating the loss of the seal which, after several uses and disassemblies, tends to escape from its housing.
La présente invention propose de remédier aux différents inconvénients des systèmes d'étanchéité utilisés actuellement sur les raccords et en particulier sur les raccords rapides pour la collecte du lait. The present invention proposes to overcome the various disadvantages of the sealing systems currently used on the fittings and in particular on the quick couplings for the collection of milk.
Le système de joint d'étanchéité selon l'invention concerne des raccords rapides comprenant une partie sédentaire, solidaire de la cuve de stockage du genre tank à lait, et une partie nomade disposée à l'extrémité d'un conduit relié à une citerne de collecte par exemple, lesquelles parties sont munies chacune d'une surface radiale de contact aménagée pour procurer l'étanchéité par l'intermédiaire d'au moins un joint souple, lequel joint est disposé dans une The seal system according to the invention relates to quick couplings comprising a sedentary part, integral with the storage tank of the milk tank type, and a nomadic part arranged at the end of a duct connected to a tank of water. for example, which parts are each provided with a radial contact surface arranged to provide sealing by means of at least one flexible seal, which seal is arranged in a
<Desc/Clms Page number 2><Desc / Clms Page number 2>
rainure en creux aménagée dans l'une desdites parties, laquelle rainure comporte une section trapézoïdale, se resserrant côté extérieur, pour loger de façon contraignante ledit joint dont la section est telle qu'il est introduit à force dans ladite rainure, lequel joint coopère avec un bossage circulaire disposé sur la surface radiale de l'autre partie, lequel bossage est centré par rapport à ladite rainure, prenant appui sur ledit joint. recessed groove formed in one of said parts, which groove comprises a trapezoidal section, tightening on the outer side, to constrainly seat said seal whose section is such that it is forced into said groove, which seal cooperates with a circular boss disposed on the radial surface of the other portion, which boss is centered relative to said groove, bearing on said seal.
Selon une disposition préférentielle de l'invention, le joint annulaire a une section polygonale du genre rectangulaire, son épaisseur correspond sensiblement à la profondeur de la rainure et sa largeur correspond sensiblement à la largeur du fond de ladite rainure. According to a preferred embodiment of the invention, the annular seal has a rectangular polygonal section, its thickness substantially corresponds to the depth of the groove and its width substantially corresponds to the width of the bottom of said groove.
Toujours selon l'invention, la largeur de l'entrée de la rainure est inférieure de quelques dixièmes à la largeur du fond de la rainure. Still according to the invention, the width of the entrance of the groove is a few tenths less than the width of the bottom of the groove.
Selon une autre disposition de l'invention, le bossage a une section en forme de segment circulaire dont la largeur est inférieure à la largeur de la rainure et dont la hauteur est de l'ordre de 0,5 à 2 mm par exemple. According to another embodiment of the invention, the boss has a circular segment-shaped section whose width is less than the width of the groove and whose height is of the order of 0.5 to 2 mm for example.
Selon une autre disposition préférentielle de l'invention, le joint est disposé dans une rainure aménagée en creux dans la surface radiale de la partie sédentaire du raccord rapide. According to another preferred embodiment of the invention, the gasket is disposed in a groove formed in the radial surface of the sedentary portion of the quick coupling.
L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés donnés à titre indicatif, et dans lesquels : - la figure 1 représente schématiquement les parties basiques agrandies localement, d'un raccord rapide installé entre une cuve de stockage et un conduit relié à une citerne ; - la figure 2 représente une portion du joint d'étanchéité ; - la figure 3 représente une coupe partielle de la partie sédentaire du raccord ; - la figure 4 représente une coupe partielle de la partie nomade du raccord ; - la figure 5 représente une coupe partielle du raccord rapide en position normale d'accouplement étanche. The invention will be further detailed with the aid of the following description and accompanying drawings given for information only, and in which: - Figure 1 shows schematically the basic parts enlarged locally, a quick connector installed between a storage tank and a conduit connected to a tank; - Figure 2 shows a portion of the seal; - Figure 3 shows a partial section of the sedentary portion of the connector; - Figure 4 shows a partial section of the nomad part of the connection; - Figure 5 shows a partial section of the quick connector in normal position of sealing.
La figure 1 montre de façon schématique, les deux parties basiques, en forme de douilles, d'un raccord rapide 1 qui permet de relier une cuve de stockage 2 ou tank à lait, à la citerne 3 d'un véhicule de collecte. Figure 1 shows schematically, the two basic parts, in the form of sockets, a quick connector 1 which allows to connect a storage tank 2 or tank to milk tank 3 of a collection vehicle.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
La cuve 2 comporte un embout 4 situé à sa partie inférieure, en aval d'une vanne 5 qui isole le contenu de cette cuve par rapport à l'extérieur. Cet embout 4 constitue la partie sédentaire du raccord. The tank 2 comprises a nozzle 4 located at its lower part, downstream of a valve 5 which isolates the contents of this tank relative to the outside. This tip 4 is the sedentary part of the connection.
L'autre partie du raccord 1 est constituée d'une pièce nomade 6 disposée à l'extrémité d'un conduit souple de façon à pouvoir raccorder la citerne 3 à la cuve 2. The other part of the connection 1 consists of a nomadic part 6 disposed at the end of a flexible conduit so as to connect the tank 3 to the tank 2.
Les moyens de raccordement de ces deux parties 4 et 6, c'est-à-dire les moyens de centrage et de serrage, sont propres aux raccords rapides et ne font pas partie de l'invention. Ces moyens sont de différents types comme on peut le constater à la lecture des documents FR-2 679 314, 2 730 550, 2 749 919 et 2 808 863 par exemple. The connecting means of these two parts 4 and 6, that is to say the centering and clamping means, are specific to quick couplings and do not form part of the invention. These means are of different types, as can be seen from the documents FR-2 679 314, 2 730 550, 2 749 919 and 2 808 863 for example.
L'embout 4 et la pièce 6 sont séparés par un joint 7. The tip 4 and the piece 6 are separated by a seal 7.
Ce joint 7 est de préférence disposé sur l'embout 4 qui constitue la partie sédentaire du raccord. This seal 7 is preferably arranged on the tip 4 which constitutes the sedentary portion of the coupling.
L'embout 4 du raccord comporte une surface radiale 10, figure 3, et la partie 6 une surface radiale 11, figure 4. Ces deux surfaces radiales s'appliquent l'une sur l'autre lorsque la jonction est réalisée. The tip 4 of the connector has a radial surface 10, Figure 3, and the part 6 a radial surface 11, Figure 4. These two radial surfaces are applied to one another when the junction is made.
L'embout 4 comporte, ouverte du côté de la surface radiale 10, une rainure 12 qui est circulaire, et qui est aménagée pour accueillir le joint 7, figure 2. The tip 4 comprises, open on the side of the radial surface 10, a groove 12 which is circular, and which is arranged to receive the seal 7, Figure 2.
Cette rainure circulaire a une section trapézoïdale qui se rétrécit et se referme sur l'extérieur, c'est-à-dire au niveau de la surface radiale 10. This circular groove has a trapezoidal section which narrows and closes on the outside, that is to say at the level of the radial surface 10.
Le joint 7 a une section polygonale, rectangulaire par exemple, et ses dimensions sont telles que sa mise en place dans la rainure 12 s'effectue à force, de préférence avec un produit lubrifiant approprié. The seal 7 has a polygonal section, rectangular for example, and its dimensions are such that its implementation in the groove 12 is forced, preferably with a suitable lubricant.
Le joint 7 est réalisé par exemple par moulage, en un matériau approprié du genre silicone. The seal 7 is made for example by molding, in a suitable material of the silicone type.
L'épaisseur E du joint est du même ordre que la profondeur P de la rainure 12 voire légèrement inférieure de quelques dixièmes de millimètres. The thickness E of the seal is of the same order as the depth P of the groove 12 or slightly less than a few tenths of a millimeter.
La largeur L du joint est du même ordre que la largeur Lf du fond de la rainure 12. The width L of the seal is of the same order as the width Lf of the bottom of the groove 12.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
La largeur Le de l'entrée de la rainure 12, au niveau de la surface radiale 10, est légèrement inférieure à la largeur L du joint, de l'ordre de quelques dixièmes de millimètres, 2 à 4/1 Oèmes par exemple. The width of the inlet of the groove 12 at the radial surface 10 is slightly less than the width L of the seal, of the order of a few tenths of a millimeter, 2 to 4/1 oèmes for example.
De cette façon le joint 7 remplit totalement la cavité de la rainure 12 et, de plus, il est comprimé dans cette rainure avec une tendance, grâce à la section trapézoïdale de ladite rainure, à s'enfoncer dans cette dernière. In this way the seal 7 completely fills the cavity of the groove 12 and, moreover, it is compressed in this groove with a tendency, thanks to the trapezoidal section of said groove, to sink into the groove.
Ainsi, le joint 7 fait étanchéité avec les parois latérales 13 et 14 de la rainure 12, évitant toute pénétration de produit quelconque entre lui-même et lesdites parois. Thus, the seal 7 seals with the side walls 13 and 14 of the groove 12, avoiding any penetration of any product between itself and said walls.
Contrairement aux techniques classiques utilisées notamment pour les produits alimentaires du genre lait ou autres, le joint 7 n'est pas prévu pour être démontable à chaque opération de collecte. L'hygiène est parfaitement respectée en raison du fait que le joint 7 comble totalement la rainure 12 et réalise une étanchéité au niveau des entrées de la rainure 12, laquelle étanchéité est renforcée lorsque le raccord est opérationnel, c'est-à-dire lorsque la pièce 6 est placée contre l'embout 4 comme représenté figure 5. Unlike conventional techniques used in particular for food products of the milk type or other, the seal 7 is not intended to be removable at each collection operation. Hygiene is perfectly respected because the seal 7 completely fills the groove 12 and provides a seal at the inlets of the groove 12, which sealing is reinforced when the connection is operational, that is to say when the piece 6 is placed against the tip 4 as shown in FIG.
La pièce nomade 6 comporte, sur sa surface radiale 11, un bourrelet circulaire 16 qui est coaxial à la rainure 12 et au joint 7. Ce bourrelet 16 a une section en forme de segment circulaire avec une largeur D qui est inférieure à la largeur Le de l'entrée de la rainure. La hauteur ou saillie S de ce bourrelet par rapport à la surface radiale 11, est comprise entre 0,5 et 2 mm. The nomadic piece 6 comprises, on its radial surface 11, a circular bead 16 which is coaxial with the groove 12 and the seal 7. This bead 16 has a section in the form of a circular segment with a width D which is less than the width The width from the entrance of the groove. The height or projection S of this bead with respect to the radial surface 11 is between 0.5 and 2 mm.
La forme de ce bossage 16 permet d'éviter de blesser le joint et aussi de détériorer les rebords de la rainure 12. The shape of this boss 16 avoids hurting the seal and also damage the edges of the groove 12.
On remarque, figure 5, que le bossage 16 comprime le joint 7 dans la cavité de la rainure 12. Le joint 7 se comprime et se déforme, autour du bossage 16, renforçant l'étanchéité entre l'embout 4 et la pièce 6 et évitant tout risque d'infiltration de produit entre le joint 7 et les parois latérales de la rainure 12. Note, in FIG. 5, that the boss 16 compresses the seal 7 in the cavity of the groove 12. The seal 7 compresses and deforms around the boss 16, reinforcing the seal between the endpiece 4 and the part 6 and avoiding any risk of product infiltration between the seal 7 and the side walls of the groove 12.
