Abstract
Description
La présente invention est relative à des perfectionnements au dispositif de commande d'une vanne plus particulièrement destinés à celles comportant un corps tel que décrit-dans le brevet Français 84 02 409 publié sous le N" 2 559 871. The present invention relates to improvements to the device for controlling a valve, more particularly intended for those comprising a body as described in French patent 84 02 409 published under No. 2,559,871.
On sait que, s'il est facile de réaliser une étanchéité quasi parfaite entre deux pièces assemblées l'une à l'autre de.façon fixe, il n'en est pas de même lorsque l'un des pièces peut pivoter par rapport à l'autre. We know that, while it is easy to achieve an almost perfect seal between two parts assembled to each other de.faix fixe, it is not the same when one of the parts can pivot relative to the other.
Ainsi, sur une vanne, s'il est possible d'assurer une bonne étanchéité entre le corps et les brides de raccordement des conduites, un sérieux problème se pose au niveau de l'organe d'actionnement du boisseau sphérique qui comporte nécessairement une tige traversant le corps de ladite vanne. Thus, on a valve, if it is possible to ensure a good seal between the body and the pipe connection flanges, a serious problem arises at the level of the actuating member of the ball valve which necessarily includes a rod. passing through the body of said valve.
Les dispositifs dits à " presse-étoupe ",utilisés jusqu'à présent, n'ont pas permis d'apporter une solution satisfaisante à ce problème. The so-called "cable gland" devices used up to now have not made it possible to provide a satisfactory solution to this problem.
Selon l'invention, l'organe d'actionnement du boisseau est -logé dans un soufflet tubulaire borgne présentant à son extrémité libre une collerette fixée contre le corps de la vanne. According to the invention, the valve actuating member is -locked in a blind tubular bellows having at its free end a flange fixed against the valve body.
De cette façon, si une fuite se produit au niveau du dispositif d'actionnement de la vanne, le fluide pénetre et est retenu dans la chambre formée par le soufflet. In this way, if a leak occurs at the valve actuation device, the fluid penetrates and is retained in the chamber formed by the bellows.
L'invention sera mieux comprise par la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement sur lequel la figure unique montre le dispositif de l'invention appliqué à une vanne usuelle, à boisseau sphérique. The invention will be better understood from the description which follows, made with reference to the accompanying drawing by way of indicative example only, in which the single figure shows the device of the invention applied to a conventional valve, with a ball valve.
En se reportant au dessin, on voit que 1 est le corps de la vanne renfermant un boisseau sphérique 2 et comportant une table usinée 3 pourvue d'un pied de centrage 4 tel que décrit dans le brevet Français N" 84 02409 précité. Referring to the drawing, it can be seen that 1 is the body of the valve containing a ball valve 2 and comprising a machined table 3 provided with a centering foot 4 as described in the aforementioned French patent No. 84 02409.
L'organe d'actionnement est constitué par un levier coudé 5,pourvu,dans l'exemple représenté,d'un adaptateur 6 d'entrainement du boisseau 2. The actuating member is constituted by a bent lever 5, provided, in the example shown, with an adapter 6 for driving the plug 2.
Selon l'invention, le levier 5 est logé dans un soufflet 7 obturé en 8 à une de ses extrémités et présentant à l'autre une collerette 9 pouvant être fixée contre la table 3. According to the invention, the lever 5 is housed in a bellows 7 closed at 8 at one of its ends and having at the other a flange 9 which can be fixed against the table 3.
Dans l'exemple représenté, la collerette 9 est fixée contre la table 3, avec interposition d'une pièce intermédiaire 10, rendue nécessaire en raison de la présente sur ladite table du pied de centrage 4. In the example shown, the flange 9 is fixed against the table 3, with the interposition of an intermediate piece 10, made necessary because of the presence on said table of the centering foot 4.
Une bride 11 et des vis 12 assurent la fixation de l'ensemble. A flange 11 and screws 12 secure the assembly.
Au droit de cet ensemble de pièces, qui sont fixées les unes par rapport aux autres,l'étanchéité est facilement assurée par des joints de types connus tels que ceux 13. In line with this set of parts, which are fixed relative to one another, the seal is easily ensured by seals of known types such as those 13.
Le soufflet 7 est engagé dans un tube 14 présentant un épaulement 15 à une extrémité assurant son maintien et une poignée 16, à l'autre. The bellows 7 is engaged in a tube 14 having a shoulder 15 at one end ensuring its maintenance and a handle 16 at the other.
L'extrémité libre du levier 5 est recouverte d'un manchon 17 et celle borgne du soufflet d'un manchon 18. Les manchons 17 et 18, réalisés en une matière présentant un coefficient de frottement très faible, permettant la libre rotation du soufflet lorsqu'on agit sur la poignée 16 et relient ladite poignée et le levier coudé 5. The free end of the lever 5 is covered with a sleeve 17 and the blind end of the bellows with a sleeve 18. The sleeves 17 and 18, made of a material having a very low coefficient of friction, allowing the bellows to rotate freely when we act on the handle 16 and connect said handle and the bent lever 5.
Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiment described and shown but extends, on the contrary, to all variants of shapes and dimensions.
Naturellement, le dispositif de l'invention peut être utilisé pour réaliser un allonge cryogénique il suffit, pour cela, que le levier 5, le soufflet 7 et le tube 14 présentent, chacun, une partie rectiligne,de la longueur désirée. située dans le prolongement de l'axe de rotation du boisseau 2. Naturally, the device of the invention can be used to produce a cryogenic extension, it suffices, for this, that the lever 5, the bellows 7 and the tube 14 each have a rectilinear part, of the desired length. located in the extension of the axis of rotation of the plug 2.
