Abstract
Description
La présente invention est relative à des perfectionnements aux corps de vannes du genre de celles dont ledit corps, renfermant un organe d'obturation tel qu'un boisseau sphérique, est serré à l'aide de tirants, entre deux brides de raccordement aux canalisations. The present invention relates to improvements to valve bodies of the kind of which said body, containing a shutter member such as a ball, is tightened with tie rods, between two flanges for connection to the pipes.
En l'état actuel de la technique le corps de la vanne est traversé par un tirant constitué par un boulon. Cette disp- sition permet au corps de pivoter autour de l'axe du boulan le traversant afin de permettre l'accès à l'intérieur sans toutefois le démonter, ledit corps se comportant comme une entretoise en maintenant l'écartement entre les brides en vue, par exemple, du changement des joints ou du boisseau. In the current state of the art the valve body is crossed by a tie rod constituted by a bolt. This arrangement allows the body to pivot around the axis of the bolt passing through it in order to allow access to the interior without, however, dismantling it, said body behaving like a spacer while maintaining the spacing between the flanges in view. , for example, changing the seals or the bushel.
Pour certaines applications, il est nécessaire d'adjoindre à la vanne un organe permettant de la commander à distance. For certain applications, it is necessary to add to the valve a member making it possible to control it remotely.
Un tel organe, dénommé ci-après actionneur" est fixé sur la vanne à l'aide d'équerres maintenues par les tirants usuels d'où une certaine difficulté de centrage et l'impossibilité de fixer un tel actionneur sans interrompre le circuit.Such a member, hereinafter referred to as an actuator "is fixed to the valve by means of brackets maintained by the usual tie rods, hence a certain difficulty in centering and the impossibility of fixing such an actuator without interrupting the circuit.
Par ailleurs, lorsque la vanne est utilisée sur un circuit comportant un fluide à très basse température, il est nécessai~ re de lui adjoindre une allonge cryogénique, constituée essentellement par un tube, soudé sur le corps et traversé par un arbre prolongeant celui usuel de-commande du boisseau.Comme l'allonge n'est pas démontable, une telle vanne ne peut pas être transformée en vanne ordinaire. Furthermore, when the valve is used on a circuit comprising a fluid at a very low temperature, it is necessary to add a cryogenic extension, essentially consisting of a tube, welded to the body and crossed by a shaft extending the usual one of -control of the bushel. As the extension is not removable, such a valve cannot be transformed into ordinary valve.
La présente invention, qui remédie à ces inconvénients, est remarquable en ce que le corps de la vanne est prévu pour être traversé par deux tirants adjacents situés de part et d'autre d'une table présentant un pied de centrage,disposé coaxialement à l'axe de rotation du boisseau, autour duquel sont prévus des trous borgnes taraudés destinés à la fixation de l'actionneur ou de l'allonge. The present invention, which overcomes these drawbacks, is remarkable in that the valve body is designed to be crossed by two adjacent tie rods located on either side of a table having a centering foot, arranged coaxially with the 'axis of rotation of the plug, around which are provided tapped blind holes intended for fixing the actuator or the extension.
La présente invention sera mieux comprise par la description qui va suivre, faite en se référant aux dessins annexés à titre d'exemple indicatif seulement,sur lesquels:
La figure 1 est une vue en élévation d'une vanne usuelle munie de son actionneur;
La figure 2 est une vue en coupe effectuée selon la ligne Il-Il de la figure 1 les joints et le boisseau n'étant pas représentés
La figure 3 est une vue en perspective d'un corps de vanne conforme à l'invention ;
La figure 4 est une vue analogue à la figure 1 relative au dispositif de l'invention;
La figure 5 est une vue en coupe effectuée selon la ligne
V-V de la figure 4;
La figure 6 est une vue en coupe longitudinale d'une vanne comportant le corps de l'invention auquel est fixée une allonge cryogénique.The present invention will be better understood from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is an elevational view of a conventional valve provided with its actuator;
Figure 2 is a sectional view taken along the line II-II of Figure 1 the joints and the plug are not shown
Figure 3 is a perspective view of a valve body according to the invention;
Figure 4 is a view similar to Figure 1 relating to the device of the invention;
Figure 5 is a sectional view taken along the line
VV of Figure 4;
Figure 6 is a longitudinal sectional view of a valve comprising the body of the invention which is attached a cryogenic extension.
En se reportant aux figures 1 et 2 des dessins, on voit que 1 est un corps de vanne serré entre-deux brides 2 et 3 par l'entremise de tirants 4-5-6 et 7. Comme cela ressort de la figure 2, seul le tirant 4 traverse le corps 1. Referring to FIGS. 1 and 2 of the drawings, it can be seen that 1 is a valve body clamped between two flanges 2 and 3 by means of tie rods 4-5-6 and 7. As can be seen from FIG. 2, only the tie rod 4 crosses the body 1.
Cette vanne supporte, par l'entremise de deux pattes 8 en équerre, un actionneur 9, et lesdites équerres sont fixées à la vanne par l'intermédiaire des tirants 4 et 5. This valve supports, by means of two brackets 8 at right angles, an actuator 9, and said brackets are fixed to the valve by means of tie rods 4 and 5.
Comme les faces externes des brides 2 et 3 sont généralement brutes de fonderie la fixation des pattes 8 pose certains problèmes notamment en ce qui concerne l'alignement entre l'axe de l'arbre de l'actionneur et celui du boisseau de la vanne. As the external faces of the flanges 2 and 3 are generally rough cast, the fixing of the lugs 8 poses certain problems in particular as regards the alignment between the axis of the actuator shaft and that of the valve plug.
A celà s'ajoute le fait qu'il est nécessaire, pour monter ou démonter l'actionneur, d'interrompre la circulation du fluide puisqu'il faut ôter les tirants 4 et 5. To this is added the fact that it is necessary, to mount or dismount the actuator, to interrupt the circulation of the fluid since it is necessary to remove the tie rods 4 and 5.
La présente invention remédie à ces inconvénients par l'utilisation d'un corps 10, particulier, présentant deux alésages 11 et 12 de passage, respectivement,des tirants 4 et 5 usuels. The present invention overcomes these drawbacks by the use of a body 10, particular, having two bores 11 and 12 for passage, respectively, the usual tie rods 4 and 5.
La face du corps située entre ces deux alésages est usinée pour former une table 13 comportant un pied de centrage 14 dont l'axe est confondu avec celui de l'arbre d'actionnement 15 usuel du boisseau 15 ( figure 5). The face of the body located between these two bores is machined to form a table 13 comprising a centering foot 14, the axis of which coincides with that of the usual actuation shaft 15 of the plug 15 (FIG. 5).
La table 13, qui est perpendiculaire à l'axe de rotation du boisseau, présente en outre des trous 17 borgnes et taraudés disposés de préférence selon une circonférence concentrique au pied de centrage 14. The table 13, which is perpendicular to the axis of rotation of the plug, also has blind and tapped holes 17 preferably arranged around a circumference concentric with the centering foot 14.
Comme cela ressort des figures 4 et 5, les trous 17 sont uti lisés pour fixer la pièce I8 de support de l'actionneur 9. As can be seen from FIGS. 4 and 5, the holes 17 are used to fix the piece I8 for supporting the actuator 9.
De préférence,cette pièce I8 se centre automatiquement par l'entremise du pied 14 ( figure 5). Preferably, this piece I8 centers itself automatically by means of the foot 14 (FIG. 5).
Le fait que le corps de la vanne soit traversé par deux tirants ne complique pas l'accès au boisseau puisque, déjà dans les vannes connues ( figure 2),il était nécessaire de démonter le tirant 5 pour permettre le pivotement dudit corps. The fact that the body of the valve is crossed by two tie rods does not complicate access to the plug since, already in known valves (Figure 2), it was necessary to dismantle the tie rod 5 to allow the pivoting of said body.
Par contre,cette disposition présente de nombreux avantages dont le plus important réside dans le fait qu'il est possible de monter ou de démonter l'actionneur 9 sans interrompre le circuit. However, this arrangement has many advantages, the most important of which is that it is possible to mount or dismount the actuator 9 without interrupting the circuit.
Par ailleurs, il est également possible de transformer une vanne usuelle en vanne cryogénique et inversement comme cela ressort tout particulièrement de la figure 6. Furthermore, it is also possible to transform a conventional valve into a cryogenic valve and vice versa, as is particularly apparent from FIG. 6.
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.
