Abstract

Device for controlling a valve characterised in that the shaft 4-6 for driving the spool is driven, in one direction, by the usual operating lever 7 and, in the other direction, by the relaxation of a coil spring 8. The spring 8 is housed in a casing made in two parts 11-12 fixed to the body 1 of the valve and traversed by the shaft 4-6 for driving the spool, one of the ends of the said spring being connected to the said shaft and the other to the said casing. The outer end of the spring 8 is connected to the upper part 12 of the casing.

Description

La présente invention est relative à un dispositif de commande d'une vanne, du genre de celle fonctionnant,notamment, par " tout ou rien
De telles vannes sont, soit constamment ouvertes, soit constamment fermées et, en l'absence d'action sur le levier de manoeuvre, elles doivent rester dans leur état initial (ouvert ou fermé) ou y revenir naturellement, dès que l'action sur le levier de manoeuvre cesse.The present invention relates to a device for controlling a valve, of the type operating in particular by "all or nothing".
Such valves are either constantly open or constantly closed and, in the absence of action on the operating lever, they must remain in their initial state (open or closed) or return to it naturally, as soon as the action on the operating lever stops.

Selon l'invention, ce résultat est obtenu à l'aide d'un ressort spirale dont une extrémité est reliée à l'arbre d'entrainement du boisseau. tandis que l'autre est relié au corps de la vanne. According to the invention, this result is obtained using a spiral spring, one end of which is connected to the drive shaft of the plug. while the other is connected to the valve body.

Lorsqu'on agit sur le levier de manoeuvre, on augmente la tension du ressort et celui-ci entraine alors l'arbre du boisseau; si on relâche le levier,le ressort se détend et fait pivoter ledit arbre, en sens inverse,
D'autres caractéristiques ressortiront mieux 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 coupe verticale, d'une vanne à boisseau comportant le dispositif de l'invention;
La figure 2 est la vue de dessus de la figure 1,
La figure 3 est une vue , en coupe. effectuée selon la ligne
III-III de la figure 1;
Les figures 4 et 5 sont des vues analogues à celle 2, montrant la possibilité de régler la tension initiale du. ressort.When acting on the operating lever, the spring tension is increased and the latter then drives the plug shaft; if the lever is released, the spring relaxes and causes said shaft to pivot, in the opposite direction,
Other characteristics will emerge more clearly from the description which follows, made with reference to the accompanying drawings by way of indicative example only, in which:
Figure 1 is a view, in vertical section, of a ball valve comprising the device of the invention;
FIG. 2 is the top view of FIG. 1,
Figure 3 is a sectional view. performed along the line
III-III of Figure 1;
Figures 4 and 5 are views similar to that 2, showing the possibility of adjusting the initial tension of the. spring.

En se reportant aux dessins, on voit que la vanne est constituée, de la façon connue. par un corps 1 renfermant un boisseau sphérique 2, enserré entre deux brides 3, la rotation du boisseau 2 étant commandée par un arbre 4 usuel, à doigt d'entraînement 5. Referring to the drawings, it can be seen that the valve is constituted, in the known manner. by a body 1 containing a ball valve 2, enclosed between two flanges 3, the rotation of the valve 2 being controlled by a usual shaft 4, with drive finger 5.

Selon l'invention, l'arbre 4 est entrainé par un arbre auxiliaire 6 dont la rotation est déterminée. dans un sens par une action sur le levier 7 et, dans l'autre, par un ressort spirale 8. Le ressort 8 est relié par une de ses extrémités à l'arbre 6 et, par l'autre, à un boîtier rendu solidaire du corps 1 de la vanne. According to the invention, the shaft 4 is driven by an auxiliary shaft 6 whose rotation is determined. in one direction by an action on the lever 7 and, in the other, by a spiral spring 8. The spring 8 is connected by one of its ends to the shaft 6 and, by the other, to a housing made integral of valve body 1.

Le ressort 8 est bandé initialement de sorte que, dès qu'on agit sur le levier 7, on entraine le boisseau 2 tout en augmentant la tension dudit ressort. The spring 8 is initially bandaged so that, as soon as one acts on the lever 7, one drives the plug 2 while increasing the tension of said spring.

Lorsqu'on relâche le levier 7, le ressort 8 se détend et rappelle le boisseau dans sa position initiale, la rotation dudit boisseau étant alors limitée par une butée constituée, par exemple, par la tête d'une vis 9 vissée dans le boitier et contre laquelle prend appui une extension 10 du levier 7. When the lever 7 is released, the spring 8 relaxes and recalls the plug into its initial position, the rotation of said plug then being limited by a stop constituted, for example, by the head of a screw 9 screwed into the box and against which an extension 10 of the lever 7 is supported.

Selon un mode de réalisation, le boîtier est réalisé en deux parties 11 et 12 fixées l'une à l'autre, celle 11 étant fixée sur le corps 1, au moyen de vis 13. According to one embodiment, the housing is produced in two parts 11 and 12 fixed to each other, that part 11 being fixed to the body 1, by means of screws 13.

Le dispositif qui vient d'être décrit peut s'appliquer à des vannes présentant des diamètres différents c'est-à-dire à des vannes nécessitant des efforts plus ou moins grands pour actionner le boisseau,Dans ce cas. il faut pouvoir régler, à volonté, la tension initiale du ressort 8. The device which has just been described can be applied to valves having different diameters, that is to say to valves requiring greater or less effort to actuate the plug, in this case. it is necessary to be able to adjust, as desired, the initial tension of the spring 8.

Ce résultat est obtenu en prévoyant sur le boitier 12 une pluralité de trous taraudés 14, disposés selon une circonférence dont le centre est situé sur l'axe de l'arbre 6 et dans l'un quelconque desquels on peut engager la vis 9, de butée. This result is obtained by providing on the housing 12 a plurality of tapped holes 14, arranged along a circumference whose center is located on the axis of the shaft 6 and in any one of which one can engage the screw 9, stop.

Comme cela ressort de la figure 4 si on veut augmenter, par exemple, la tension du ressort 8 on fait pivoter le levier 7 selon la flèche Flet on déplace la vis 9 (du trou 14a à celui 14b). As can be seen from FIG. 4 if one wishes to increase, for example, the tension of the spring 8, the lever 7 is made to pivot according to the arrow Flet, the screw 9 is moved (from hole 14a to hole 14b).

Naturellement, ce réglage est effectué en "usine", c'est-à-dire lorsque le dispositif n'est pas monté sur la vanne.Naturally, this adjustment is made in the "factory", that is to say when the device is not mounted on the valve.

Après avoir effectué un tel réglage, et comme cela ressort de l'examen des figures 3 et 4, la position du levier est modifiée par rapport à l'axe X-Y de la vanne. After having made such an adjustment, and as appears from the examination of FIGS. 3 and 4, the position of the lever is modified relative to the axis X-Y of the valve.

Cette position du levier 7 n'est pas rationnelle car il faut que l'axe du levier occupe une position bien précise par rapport à l'axe de la vanne de façon à indiquer la " nature" de la vanne, vanne "normalement fermée " ou vanne " normalement ouverte". This position of the lever 7 is not rational because the axis of the lever must occupy a very precise position relative to the axis of the valve so as to indicate the "nature" of the valve, valve "normally closed" or "normally open" valve.

Dans le cas de l'exemple représenté, il est donc nécessaire de ramener l'axe du levier 7 en coincidence avec l'axe X-Y de la vanne, sans modifier la tension initiale du ressort 8. In the case of the example shown, it is therefore necessary to bring the axis of the lever 7 into coincidence with the axis X-Y of the valve, without modifying the initial tension of the spring 8.

Ce résultat est obtenu d'une part, en fixant l'extrémité externe du ressort à la partie supérieure 12 du boitier et, d'autre part, en prévoyant sur les deux parties du boitier des trous de fixation 15 disposés selon une circonférence C1 concentrique à celle C2 présentant les trous 14. le décalage angulaire entre deux trous adjacents étant le même sur les deux circonférences. This result is obtained on the one hand, by fixing the external end of the spring to the upper part 12 of the housing and, on the other hand, by providing on the two parts of the housing fixing holes 15 arranged according to a concentric circumference C1 to that C2 presenting the holes 14. the angular offset between two adjacent holes being the same on the two circumferences.

Dans la pratique, l'assemblage des deux parties du boitier s effectue à l'aide de vis 16 qui traversent librement la partie 12 et se vissent dans celle 11. In practice, the two parts of the case are assembled using screws 16 which pass freely through part 12 and are screwed into that 11.

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.
