Description
Bec de remplissage à ouverture asservie par un clapet de pilotage. Filling nozzle with opening controlled by a pilot valve.
La présente invention concerne un bec de remplissage alimenté par un liquide sous pression.The present invention relates to a filling spout fed with a liquid under pressure.
ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION
On connaît, en particulier du document FR-A-2 838 730 un bec de remplissage comportant un corps tubulaire dans lequel est monté un clapet principal associé à un siège de clapet pour assurer une ouverture ou une fermeture du bec de remplissage, le clapet principal étant relié à un actionneur électromagnétique. L 'actionneur électromagnétique présente l'avantage d'assurer la commande du clapet principal sans qu'il soit nécessaire de traverser la paroi du corps tubulaire de sorte que ce type de bec de remplissage est particulièrement adapté au conditionnement de produits alimen- taires.Document FR-A-2 838 730 discloses a filling spout comprising a tubular body in which is mounted a main valve associated with a valve seat to ensure opening or closing of the filling spout, the main valve being connected to an electromagnetic actuator. The electromagnetic actuator has the advantage of controlling the main valve without having to pass through the wall of the tubular body so that this type of filling spout is particularly suitable for the packaging of food products.
Toutefois, en raison du faible espace disponible, il n'est pas possible de prévoir des pièces magnétiques fournissant un champ important. La force appliquée au clapet principal pour ouvrir celui-ci est donc limitée et il est donc généralement nécessaire de prévoir des bacs tampons servant à réguler la pression en amont du bec de remplissage. La présence de ces bacs tampons constitue une contrainte tant par le volume que ces bacs tampons occupent à proximité de l'installation de remplissage, que par les problèmes bactériologiques que pose le stockage d'un liquide alimentaire dans un bac tampon.However, due to the small space available, it is not possible to provide magnetic parts providing a large field. The force applied to the main valve to open it is limited and therefore it is generally necessary to provide buffer tanks for regulating the pressure upstream of the filling spout. The presence of these buffer tanks is a constraint as much by the volume that these buffer tanks occupy near the filling installation, as the bacteriological problems posed by the storage of a liquid food in a buffer tank.
OBJET DE L'INVENTIONOBJECT OF THE INVENTION
Un but de 1 ' invention est de proposer un bec de remplissage comportant un dispositif de commande du cla- pet principal pouvant fonctionner avec des pressions d'alimentation élevées.An object of the invention is to provide a filling spout comprising a control device of the main valve operable with high supply pressures.
RESUME DE L'INVENTIONSUMMARY OF THE INVENTION
En vue de la réalisation de ce but, on propose selon l'invention un bec de remplissage comportant un corps tubulaire dans lequel est monté un siège de clapet
auquel est associé un clapet principal relié à un piston s 'étendant dans une cavité de pilotage reliée à un orifice d'échappement et à un conduit de pilotage ayant un orifice de pilotage pourvu d'un clapet de pilotage com- mandé, le conduit de pilotage débouchant sur une face de piston provoquant un déplacement du clapet principal vers une position d'ouverture lorsque le conduit de pilotage est alimenté en liquide sous pression.With a view to achieving this object, it is proposed according to the invention a filling spout comprising a tubular body in which is mounted a valve seat which is associated with a main valve connected to a piston extending in a pilot cavity connected to an exhaust port and to a pilot duct having a pilot orifice provided with a controlled piloting flap, the pilot duct control opening on a piston face causing a movement of the main valve to an open position when the control conduit is supplied with liquid under pressure.
Ainsi, en prévoyant un clapet de pilotage de fai- ble dimension, il est facile de manœuvrer celui-ci au moyen d'un actionneur électromagnétique, même lorsque le liquide à conditionner est à une pression élevée, et la pression admise dans la cavité de pilotage exerce sur le clapet principal une force d' actionnement qui est fonc- tion de la surface du piston. Quelle que soit la pression d'alimentation du liquide, il est donc possible de commander l'ouverture du clapet principal par un dimension- nement approprié du piston par rapport à la dimension du clapet principal . Selon une version avantageuse de l'invention, le clapet principal est relié au piston par une liaison tu- bulaire formant le conduit de pilotage monté coaxialement au clapet principal. Ainsi, l'ensemble obtenu est particulièrement compact. Selon un autre aspect avantageux de l'invention, le clapet de pilotage est relié par une tige de pilotage à un obturateur assurant une fermeture de l'orifice d'échappement lors de l'ouverture de l'orifice de pilotage. On obtient ainsi l'ouverture rapide du clapet prin- cipal.Thus, by providing a pilot valve of small size, it is easy to maneuver it by means of an electromagnetic actuator, even when the liquid to be conditioned is at a high pressure, and the pressure admitted into the cavity of piloting exerts on the main valve an actuating force which is a func - tion of the surface of the piston. Whatever the supply pressure of the liquid, it is therefore possible to control the opening of the main valve by an appropriate dimensioning of the piston relative to the size of the main valve. According to an advantageous version of the invention, the main valve is connected to the piston by a tubular connection forming the control duct mounted coaxially with the main valve. Thus, the assembly obtained is particularly compact. According to another advantageous aspect of the invention, the pilot valve is connected by a control rod to a shutter ensuring closing of the exhaust port when opening the pilot orifice. This gives the quick opening of the main valve.

DESCRIPTION DETAILLEE DE L'INVENTION En référence aux dessins, le bec de remplissage comporte de façon connue en soi du document précité un corps tubulaire 1 comprenant trois éléments 1.1, 1.2 et 1.3 reliés entre eux par des attaches rapides non représentées. L'élément de corps 1.1 est relié à un dispositif d'alimentation en liquide sous pression. L'élément de corps 1.2 comporte une cloison transversale 2 comportant une ouverture centrale 3 formant un siège de clapet au- quel est associé un clapet principal 4.DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings, the filling spout comprises, in a manner known per se of the above-mentioned document, a tubular body 1 comprising three elements 1.1, 1.2 and 1.3 interconnected by fast fasteners, not shown. The body member 1.1 is connected to a liquid supply device under pressure. The body member 1.2 comprises a transverse partition 2 having a central opening 3 forming a valve seat with which is associated a main valve 4.
Selon le mode de réalisation illustré de l'invention, le clapet principal 4 est percé d'un orifice de pilotage 15 coaxial au clapet principal 4. En outre, le clapet principal 4 est relié, par un conduit de pilotage tubulaire 5 s 'étendant coaxialement au clapet principal 4, à un piston 6 de section circulaire montée pour coulisser dans une cavité de pilotage cylindrique 7 réalisée à l'extrémité supérieure d'un noyau 8 fixé à l'intérieur de l'élément de corps 1.2 par une collerette 9 comportant des lumières oblongues 10 permettant un écoulement du liquide autour du noyau 8. La cavité de pilotage 7 débouche à la partie supérieure du noyau 8 de sorte qu'elle comporte une ouverture permettant au piston de sortir de la cavité de pilotage lors d'un déplacement du clapet prin- cipal 4 vers la position d'ouverture.
Un conduit d'échappement 11 de section circulaire traverse verticalement le noyau 8 coaxialement au conduit de pilotage tubulaire 5. Le conduit d'échappement 11 débouche a son extrémité supérieure dans le fond de la ca- vite 7 et comporte à son extrémité inférieure un orifice d'échappement 12 auquel est associé un obturateur 13 fixé à l'extrémité inférieure d'une tige de pilotage 14 de section carrée (figure 3) dont les arêtes verticales 15 sont guidées par la paroi interne du conduit d'échappe- ment 11.According to the illustrated embodiment of the invention, the main valve 4 is pierced with a pilot orifice 15 coaxial with the main valve 4. In addition, the main valve 4 is connected by a tubular piloting conduit 5 extending coaxially with the main valve 4, a piston 6 of circular section mounted to slide in a cylindrical piloting cavity 7 formed at the upper end of a core 8 fixed inside the body member 1.2 by a flange 9 having oblong slots 10 allowing a liquid flow around the core 8. The piloting cavity 7 opens at the upper part of the core 8 so that it has an opening allowing the piston to leave the piloting cavity during a moving the main valve 4 to the open position. An exhaust duct 11 of circular cross section vertically passes through the core 8 coaxially with the tubular pilot duct 5. The exhaust duct 11 opens at its upper end into the bottom of the casing 7 and has at its lower end an orifice exhaust 12 which is associated with a shutter 13 attached to the lower end of a control rod 14 of square section (Figure 3), the vertical edges 15 are guided by the inner wall of the exhaust duct 11.
La tige de pilotage 14 s'étend verticalement dans le conduit de pilotage 5 et dans l'orifice de pilotage 15 du clapet principal 4. Un clapet de pilotage 16 est fixé à l'extrémité supérieure de la tige de pilotage 14. Le clapet de pilotage 16 est relié de façon démontable à une tige de commande 17 elle-même reliée à un actionneur non représenté .The control rod 14 extends vertically in the piloting duct 5 and in the pilot valve 15 of the main valve 4. A pilot valve 16 is fixed to the upper end of the control rod 14. The flap of FIG. pilot 16 is removably connected to a control rod 17 itself connected to a not shown actuator.
Dans la position illustrée sur la figure 1, le bec de remplissage est en position fermée, c'est-à-dire que le clapet principal 4 est en appui sur son siège 3 et le clapet de pilotage 16 ferme l'orifice de pilotage 15 tandis que l'obturateur 13 est écarté de l'orifice d'échappement 12. Le clapet principal 4 et le clapet de pilotage 16 assurent donc une séparation étanche entre la chambre d'alimentation 18 délimitée par l'élément de corps 1.1 et la chambre de distribution 19 délimitée par les éléments de corps 1.2 et 1.3. De préférence, la chambre de distribution 19 est maintenue remplie de liquide en prévoyant un obturateur 13 dont la surface inférieure coopère avec une restriction 20 à l'extrémité inférieure du corps tubulaire 1 avec un jeu juste suffisant pour retenir par capillarité le liquide contenu dans la chambre de distribution 19 lorsque le clapet principal 4 et le clapet de pilotage 16 sont dans une position de ferme- ture . Dans cette position le piston 6 s'étend au voisi-
nage du fond de la cavité de pilotage 7.In the position illustrated in Figure 1, the filling spout is in the closed position, that is to say that the main valve 4 is supported on its seat 3 and the pilot valve 16 closes the pilot orifice 15 while the shutter 13 is spaced from the exhaust port 12. The main valve 4 and the pilot valve 16 thus provide a sealed separation between the feed chamber 18 delimited by the body member 1.1 and the chamber distribution 19 delimited by the body elements 1.2 and 1.3. Preferably, the distribution chamber 19 is kept filled with liquid by providing a shutter 13 whose lower surface cooperates with a restriction 20 at the lower end of the tubular body 1 with a fair play sufficient to retain by capillarity the liquid contained in the distribution chamber 19 when the main valve 4 and the pilot valve 16 are in a closed position. In this position the piston 6 extends to the neighboring swimming from the bottom of the pilot cavity 7.
Pour assurer une ouverture du bec de remplissage comme illustré par la figure 2, la tige de commande 17 est tirée vers le haut entraînant ainsi simultanément vers le haut le clapet de pilotage 16 qui ouvre l'orifice de pilotage 15 et l'obturateur 13 qui ferme l'orifice d'échappement 12. On notera qu'en raison de la faible dimension du clapet de pilotage 16, une force minime permet de manœuvrer celui-ci. Le liquide contenu dans la chambre d'alimentation 18 s'écoule alors à travers l'orifice de pilotage 15 et le conduit de pilotage 5, et après avoir rempli le conduit d'échappement 11, le liquide exerce une pression sur la face inférieure du piston 6. Le remplissage rapide du conduit de pilotage 5 et du conduit d'échappement 11 est favorisé par des rainures longitudinales 21 (figure 3) dans deux faces opposées de la tige de pilotage 14.To ensure an opening of the filling spout as shown in FIG. 2, the control rod 17 is pulled upwards thus simultaneously driving upwards the pilot flap 16 which opens the pilot orifice 15 and the shutter 13 which closes the exhaust port 12. Note that due to the small size of the pilot valve 16, a small force can maneuver it. The liquid contained in the feed chamber 18 then flows through the pilot orifice 15 and the control duct 5, and after having filled the exhaust duct 11, the liquid exerts a pressure on the lower face of the piston 6. The rapid filling of the control duct 5 and the exhaust duct 11 is favored by longitudinal grooves 21 (FIG. 3) in two opposite faces of the control rod 14.
Le piston 6 est dimensionné par rapport au clapet principal 4 pour que la force exercée vers le haut par le liquide sur le piston 6 dans la cavité 7 soit supérieure à la force exercée vers le bas sur le clapet principal 4 par le liquide contenu dans la chambre d'alimentation 18. Lors de l'ouverture du clapet de pilotage 16, le clapet principal 4 est alors déplacé vers sa position ouverte comme illustré sur la figure 2. Lorsque le piston 6 atteint le bord supérieur de la cavité 7, le liquide emprisonné dans la cavité 7 peut s'échapper et le clapet principal 4 est alors maintenu dans une position d'ouverture stable. Cette position est de préférence calculée pour que l'écoulement soit laminaire à la sortie du bec de remplissage. Un écoulement laminaire à la sortie du bec de remplissage est en outre favorisé en prévoyant un noyau 8 ayant une surface externe conique 22 ayant une conicité correspondante à la surface interne 23 de l'élé- ment de corps 1.3 en regard. De préférence, l'obturateur
13 a en outre une forme adaptée pour qu'en position ouverte du clapet de pilotage, la surface inférieure de l'obturateur 13 prolonge sans discontinuité la surface externe 22 du noyau 8 comme illustré par la figure 2. Pour la fermeture du bec de remplissage, le clapet de pilotage 16 est actionné vers le bas pour refermer l'orifice de pilotage 15. Dans ce mouvement l'orifice d'échappement 12 est ouvert de sorte que la pression chute sur la face inférieure du piston 6. Le clapet prin- cipal 4 se referme alors sous l'effet du poids de l'ensemble mobile et de la pression exercée par le liquide contenu dans la chambre d'alimentation 18.The piston 6 is dimensioned with respect to the main valve 4 so that the force exerted upwards by the liquid on the piston 6 in the cavity 7 is greater than the force exerted downwards on the main valve 4 by the liquid contained in the supply chamber 18. When opening the pilot valve 16, the main valve 4 is then moved to its open position as shown in FIG. 2. When the piston 6 reaches the upper edge of the cavity 7, the liquid trapped in the cavity 7 can escape and the main valve 4 is then maintained in a stable open position. This position is preferably calculated so that the flow is laminar at the outlet of the filling spout. A laminar flow at the outlet of the filling spout is further promoted by providing a core 8 having a conical outer surface 22 having a corresponding conicity to the inner surface 23 of the facing body member 1.3. Preferably, the shutter 13 also has a shape adapted so that in the open position of the pilot valve, the lower surface of the shutter 13 continuously extends the outer surface 22 of the core 8 as shown in Figure 2. For closing the filling spout , the pilot valve 16 is actuated downwards to close the pilot orifice 15. In this movement, the exhaust orifice 12 is open so that the pressure drops on the lower face of the piston 6. The main valve cipal 4 then closes under the effect of the weight of the moving assembly and the pressure exerted by the liquid contained in the feed chamber 18.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des va- riantes de réalisation sans sortir du cadre de 1 ' invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and variations can be made thereto without departing from the scope of the invention as defined by the claims.
En particulier, bien que l'invention ait été illustrée en relation avec un dispositif dans lequel le clapet de pilotage et le conduit de pilotage sont concen- triques au clapet principal 4 et au corps tubulaire 1, on peut prévoir un clapet de pilotage excentré associé à un conduit de pilotage débouchant latéralement dans le fond de la cavité 7.In particular, although the invention has been illustrated in connection with a device in which the pilot valve and the control duct are concentric with the main valve 4 and the tubular body 1, an associated eccentric pilot valve may be provided. to a pilot duct opening laterally into the bottom of the cavity 7.
De même, on peut prévoir un obturateur 13 ayant pour seule fonction d'assurer une fermeture ou une ouverture de l'orifice d'échappement sans fonction de clapet auxiliaire assurant un maintien du remplissage de la chambre de distribution 19.Similarly, it is possible to provide a shutter 13 whose sole function is to ensure closure or opening of the exhaust port without auxiliary valve function ensuring maintenance of the filling of the distribution chamber 19.
Bien que l'invention ait été décrite avec une tige de pilotage de section carrée, on peut prévoir une tige de pilotage ayant de façon plus générale une section polygonale .
Although the invention has been described with a square section drive rod, it is possible to provide a control rod having more generally a polygonal section.
