Description

La présente invention a pour a objet un dispositif de vanne papillon destiné notamment à être utilisé dans le domaine pharmaceutique. The present invention relates to a butterfly valve device intended in particular to be used in the pharmaceutical field.

On connaît déjà dans le domaine agroalimentaire des vannes papillons qui comprennent d'une part une bague caoutchouc synthétique de forme circulaire destinée -à être disposee coaxialement au conduit d'écoulement et d'autre part papillon métallique, réalisé d'une seule pièce constitué d'un disque, de diamètre sensiblement identique au diamètre interne de la bague, monté en rotation autour d'un axe qui traverse diamétralement ladite bague comportant deux orifices à cet effet. D'autre part l'axe fait saillie à ses deux extrémités de la bague pour permettre sa liaison à des moyens d'entraînement en rotation permettant de tourner ledit disque dans une position de fermeture ou d'ouverture de la vanne. Butterfly valves are already known in the food industry which, on the one hand, comprise a synthetic rubber ring of circular shape intended to be arranged coaxially with the flow duct and, on the other hand, metallic butterfly, made in one piece 'A disc, of diameter substantially identical to the internal diameter of the ring, mounted in rotation about an axis which diametrically crosses said ring having two orifices for this purpose. On the other hand the axis projects at its two ends of the ring to allow its connection to rotational drive means for turning said disc in a closed or open position of the valve.

La mise en place du papillon dans la bague effectuée manuellement en introduisant tout d'abord extrémité de l'axe du papillon dans l'un des deux orifices de la bague pour placer le disque à l'intérieur de celle-ci puis, à l'aide d'un étau, permettant de serrer et de maintenir ladite extrémité de l'axe du papillon qui fait saillie de la bague, et d'un instrument, tel qu'un tournevis, en introduisant l'autre extrémité de l'axe dans le deuxième orifice par étirement de ladite bague grâce à son élasticité. The introduction of the butterfly in the ring carried out manually by first introducing the end of the axis of the butterfly in one of the two orifices of the ring to place the disc inside of it then, at the using a vice, making it possible to tighten and hold said end of the axis of the butterfly which projects from the ring, and an instrument, such as a screwdriver, by introducing the other end of the axis in the second orifice by stretching said ring thanks to its elasticity.

Toutefois cette opération de mise en place du papil dans la bague demande une certaine dextérité de part l'opérateur qui accroît la durée de son montage. ailleurs le travail effectué est très contraignant à longue. En outre la bague peut être déformée lors de étirement. Enfin la constitution des bagues actuelles ne leur permet pas d'être utilisées dans l'industrie pharmaceutique. However, this operation of placing the papil in the ring requires a certain dexterity on the part of the operator, which increases the duration of its assembly. elsewhere the work carried out is very restrictive in the long run. In addition, the ring can be deformed during stretching. Finally, the constitution of current rings does not allow them to be used in the pharmaceutical industry.

La présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de vanne papillon destiné plus particulièrement à l'industrie pharmaceutique et permettant un montage aisé du disque de fermeture ladite vanne dans la bague support. The object of the present invention is to remedy these drawbacks by proposing a butterfly valve device intended more particularly for the pharmaceutical industry and allowing easy mounting of the closing disc of said valve in the support ring.

dispositif de vanne papillon selon la présente invention est du type comprenant d'une part une bague en élastomère de forme circulaire destinée à être placée coaxialement au conduit d'écoulement et d'autre part un papillon métallique comportant un disque d'obturation monté en rotation dans ladite bague autour d'un axe traversant diamétralement cette dernière et se caractérise essentiellement en ce que ladite bague est revêtue sur sa face interne d'une couche de polymère PTFE et en ce que ledit papillon comporte des moyens de démontage permettant de séparer ledit papillon en deux parties. butterfly valve device according to the present invention is of the type comprising on the one hand a circular elastomer ring intended to be placed coaxially with the flow conduit and on the other hand a metal butterfly comprising a closure disc mounted in rotation in said ring around an axis diametrically crossing the latter and is essentially characterized in that said ring is coated on its internal face with a layer of PTFE polymer and in that said butterfly comprises dismounting means making it possible to separate said butterfly in two parts.

Dans un mode de réalisation préférentiel de l'invention le disque d'obturation du papil se prolonge radialement par deux tiges formant l'axe de rotation dudit papillon et l'une desdites tiges est amovible et comporte des moyens permettant sa solidarisation audit disque. La tige amovible pourrait être solidarisée audit disque par exemple vissage, lequel disque comportant une zone adaptée a cet effet. Ainsi le montage du papillon dans la bague est effectué sans déformer cette derniere, en plaçant tout d'abord la partie comprenant le disque la tige fixée à ce dernier puis, une fois que le disque est disposé et centré dans ladite bague, en vissant la tige amovible dans le disque à travers la bague. In a preferred embodiment of the invention the disc for closing the papilla is extended radially by two rods forming the axis of rotation of said butterfly and one of said rods is removable and includes means allowing it to be joined to said disc. The removable rod could be secured to said disc, for example screwing, which disc having a zone suitable for this purpose. Thus the mounting of the butterfly in the ring is carried out without deforming the latter, by first placing the part comprising the disc, the rod fixed to the latter then, once the disc is disposed and centered in said ring, by screwing the removable rod in the disc through the ring.

Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a limiting embodiment thereof.

- la figure 1 représente une en élévation d'un dispositif de vanne papillon selon la présente invention dans un mode de réalisation préférentiel. - Figure 1 shows an elevation of a butterfly valve device according to the present invention in a preferred embodiment.

- la figure 2 représente une vue en perspective du papillon de la figure précédente. - Figure 2 shows a perspective view of the butterfly of the previous figure.

- la figure 3 représente une vue en perspective de la bague du dispositif selon la présente invention. Si on se réfère à la figure 1 on peut voir un dispositif de vanne papillon selon la présente invention, destiné plus particulièrement à l'industrie pharmaceutique, constitué d'une part d'une bague ronde 1 et d'autre part d'un papillon 2 permettant d'ouvrir ou de fermer la vanne papillon. - Figure 3 shows a perspective view of the ring of the device according to the present invention. If we refer to Figure 1 we can see a butterfly valve device according to the present invention, more particularly intended for the pharmaceutical industry, consisting on the one hand of a round ring 1 and on the other hand of a butterfly 2 to open or close the butterfly valve.

Le papillon 2 est constitué d'un disque 20 de diamètre sensiblement identique au diamètre de bague 1 et est monté en rotation autour d'un axe traversant diamétralement la bague 1 par deux orifices et 11 et faisant saillie de cette dernière par ses deux extrémités de manière à relier ledit axe à des moyens d'entraînement en rotation, non représentés. The butterfly 2 consists of a disc 20 of diameter substantially identical to the diameter of the ring 1 and is mounted in rotation about an axis diametrically crossing the ring 1 by two orifices and 11 and projecting from the latter by its two ends of so as to connect said axis to rotation drive means, not shown.

Si on se réfère maintenant à la figure 2 on peut voir que l'axe 21 du papillon 2 est formé par une tige metallique constituée de deux parties 22 et 23 dont l'une 22 de plus grande longueur et est fixée au disque 20, tandis que l'autre 23 est amovible. If we now refer to Figure 2 we can see that the axis 21 of the butterfly 2 is formed by a metal rod consisting of two parts 22 and 23, one of which 22 of greater length and is fixed to the disc 20, while that the other 23 is removable.

Le disque 20 comporte à sa périphérie deux élargissements 24 et 25 de forme conique, diamétralement opposés, orientés de manière que le sommet du cône se trouve dirigé vers le centre du disque en sorte la base de chaque cône se trouve au niveau du bord periphérique et forme une surface permettant respectivement de fixer la tige 22 de l'axe 21 et de solidariser la tige amovible 23 au disque 20. The disc 20 has at its periphery two enlargements 24 and 25 of conical shape, diametrically opposite, oriented so that the apex of the cone is directed towards the center of the disc so the base of each cone is at the peripheral edge and forms a surface making it possible respectively to fix the rod 22 of the axis 21 and to secure the removable rod 23 to the disc 20.

La tige amovible 23 comporte un embout fileté ' permettant sa solidarisation par vissage dans le cône 25 disque 20 qui comporte à cet effet un trou 26 dans lequel pratiqué un taraudage 26'. The removable rod 23 has a threaded end 'allowing it to be secured by screwing into the cone 25 disc 20 which for this purpose has a hole 26 in which a tapping 26' is made.

La mise en place du papillon 2 dans la bague 1 est effectué en introduisant tout d'abord tige 22 de l'axe 21 fixée au disque 20 dans l'orifice 10 la bague 1 manière à positionner et à centrer le disque 20 dans cette dernière, le taraudage 26 du cône 25 se trouvant alors regard du trou 11 pratiqué dans la bague 1,- puis en introduisant la tige amovible 23 de l'axe 21 dans le trou 11 de la bague et en la vissant par l'intermédiaire son embout fileté 23' dans le cône 25 du disque 20. The introduction of the butterfly 2 in the ring 1 is carried out by first introducing rod 22 of the axis 21 fixed to the disc 20 in the orifice 10 the ring 1 so as to position and center the disc 20 in the latter , the tapping 26 of the cone 25 then being located next to the hole 11 made in the ring 1, - then by introducing the removable rod 23 of the axis 21 in the hole 11 of the ring and by screwing it through its end piece threaded 23 'in the cone 25 of the disc 20.

S' on se réfère maintenant à la figure 3 peut voir que la bague 1 qui est réalisée par moulage à partir d'un élastomère, tel que du caoutchouc synthétique, est recouverte sur sa face interne d'une couche de polymere à forte densité tel que du PTFE et qui n'a pas contrairement aux élastomères de mémoire de forme. L'élastomère a donc pour fonction de conférer à la bague une élasticité suffisante pour qu'elle puisse présenter une bonne étanchéité à la fermeture du papillon.  Referring now to FIG. 3, it can be seen that the ring 1 which is produced by molding from an elastomer, such as synthetic rubber, is covered on its internal face with a layer of high density polymer such that of PTFE and which does not have unlike elastomers of shape memory. The elastomer therefore has the function of giving the ring sufficient elasticity so that it can have a good seal when the butterfly is closed.

La couche de polymère à forte densité (PTFE) de la bague 1 permet ainsi au dispositif de vanne selon la présente invention d'être utilisé dans l'industrie pharmaceutique. En outre, la constitution du papil en deux parties est particulièrement avantageuse puisqu'elle permet son montage dans la bague qui, du fait de la présence du PTFE, ne comporte pas une élasticité suffisante pour l'étirer lors de son montage.The layer of high density polymer (PTFE) of the ring 1 thus allows the valve device according to the present invention to be used in the pharmaceutical industry. In addition, the constitution of the papil in two parts is particularly advantageous since it allows its assembly in the ring which, due to the presence of PTFE, does not have sufficient elasticity to stretch it during its assembly.
