Description
"Dispositif anti-rotation pour robinetteries"
La présente invention concerne un dispositif antirotation pour robinetterie. Un tel dispositif est destiné à empêcher toute rotation d'une robinetterie en cours d'utilisation et par conséquent tout risque de desserrage des joints ou des raccords montés sur les canalisations d'alimentation de cette robinetterie. En effet c'est au cours de manoeuvres répétées et effectuées plus ou moins brutalement ou sans précautions particulières qu'on assiste à un tel desserrage qui peut être la cause d'accidents sérieux, notamment lorsqu'il s'agit de robinetteries d'alimentation de gaz ou de tout autre fluide pouvant présenter des dangers certains."Anti-rotation device for fittings"
The present invention relates to an anti-rotation device for valves. Such a device is intended to prevent any rotation of a valve during use and therefore any risk of loosening of the seals or fittings mounted on the supply pipes of this valve. Indeed it is during repeated maneuvers and carried out more or less brutally or without special precautions that we witness such loosening which can be the cause of serious accidents, especially when it comes to supply fittings gas or any other fluid which could present certain dangers.
A l'heure actuelle les dispositifs anti-rotation généralement utilisés font appel à des moyens tels qu'au moins un ergot solidaire de l'embase d'une robinetterie, ergot venant se loger dans un évidement réalisé dans le support destiné à recevoir ladite robinetterie. Un tel moyen présente incontestablement une résistance mécanique importante. Toutefois si l'on ne désire pas monter de robinetterie avec un tel dispositif anti-rotation il faut sectionner ledit ergot (par un coup de scie ou même par un simple coup de marteau) ce qui n'est pas toujours pratique ou ce qui risque de nécessiter ultérieurement un ajustage ou une compensation par joint appropriées. At present, the generally used anti-rotation devices use means such as at least one lug secured to the base of a valve, which lug is housed in a recess made in the support intended to receive said valve. . Such a means undoubtedly has significant mechanical strength. However, if one does not wish to mount valves with such an anti-rotation device, it is necessary to cut off said pin (by a saw or even by a simple hammer blow) which is not always practical or which risks to subsequently require an appropriate joint adjustment or compensation.
Les dispositifs anti-rotation connus peuvent aussi faire appel à des systèmes associés à la queue d'une robinetterie et comportant au moins un moyen du type rondelle avec ergots et griffes dont le rôle et la fonction sont finalement de pénétrer et de s'amarrer fortement dans le support recevant ladite robinetterie. On citera aussi les systèmes à plaque et ergot pénétrant dans un orifice préalablement percé dans ledit support. Known anti-rotation devices can also use systems associated with the stem of a valve and comprising at least one washer type means with lugs and claws whose role and function are ultimately to penetrate and moor strongly in the support receiving said fitting. Mention will also be made of plate and lug systems penetrating an orifice previously drilled in said support.
De tels dispositifs loin d'être inefficaces font intervenir un nombre plus ou moins grand de pièces dont certaines doivent être usinées ce qui grève le prix de revient final du dispositif commercialisable. Far from being ineffective, such devices involve a greater or lesser number of parts, some of which must be machined, which increases the final cost price of the marketable device.
La présente invention fournit un dispositif efficace, de réalisation industrielle simple et économique et de pose extrèmement facile. The present invention provides an effective device, simple and economical industrial production and extremely easy installation.
Ce dispositif selon l'invention est essentiellement caractérisé par le fait qu'il consiste en un tampon en un matériau compressible comportant au moins un puits le traversant sur toute son épaisseur et adapté pour recevoir une pièce amovible destinée à faire saillie hors dudit puits et par le fait qu'il comporte des moyens pour la compression dudit tampon lorsque celui-ci est inséré entre le corps du robinet et le support sur lequel la robinetterie doit être montée pour constituer un joint d'étanchéité et un moyen d'adhérence avec ledit support. This device according to the invention is essentially characterized in that it consists of a pad made of a compressible material comprising at least one well passing through it over its entire thickness and adapted to receive a removable part intended to protrude out of said well and by the fact that it comprises means for compressing said pad when the latter is inserted between the body of the tap and the support on which the taps are to be mounted to constitute a seal and a means of adhesion with said support .
Suivant d'autres caractéristiques
- ledit tampon en matériau compressible est logé à l'intérieur d'une pièce de protection adaptée pour être rendue solidaire de la queue d'une robinetterie et pour être insérée entre le corps du robinet et le support sur lequel doit être montée ladite robinetterie, des moyens du type écrous étant prévus pour permettre la compression dudit matériau contre ledit support pour former ledit joint d'étanchéité
- la pièce amovible destinée à faire saillie hors dudit puits est adaptée pour coopérer avec un évidement réalisé dans ledit support.According to other characteristics
said pad of compressible material is housed inside a protective part adapted to be secured to the tail of a valve and to be inserted between the body of the valve and the support on which said valve is to be mounted, nut-type means being provided to allow compression of said material against said support to form said seal
- The removable part intended to protrude from said well is adapted to cooperate with a recess made in said support.
D'autres caractéristiques et les avantages de l'invention ressortiront plus clairement de la description qui va suivre faite en regard des dessins annexés sur lesquels
- la figure 1 est une vue en élévation-coupe axiale d'une robinetterie montée sur son support avec le dispositif anti-rotation selon l'invention ;
- la figure 2 est une vue en élévation-coupe montrant en détail les différentes pièces constitutives du dispositif de l'invention avant sa fixation définitive
- la figure 3 est une vue analogue à celle de la figure 2 mais après fixation dudit dispositif et
- les figures 4a - 4b sont des vues respectivement en élévation et en plan, à plus grande échelle, d'une des pièces constitutives principales du dispositif selon l'invention.Other characteristics and advantages of the invention will emerge more clearly from the description which follows, given with reference to the appended drawings in which
- Figure 1 is an axial sectional elevation view of a valve mounted on its support with the anti-rotation device according to the invention;
- Figure 2 is an elevation-sectional view showing in detail the various component parts of the device of the invention before its final fixing
- Figure 3 is a view similar to that of Figure 2 but after fixing said device and
- Figures 4a - 4b are views respectively in elevation and in plan, on a larger scale, of one of the main component parts of the device according to the invention.
En se référant à ces figures la robinetterie illustrée à la figure 1 comprend un bec coudé 1 inséré dans le corps de robinet 2, ce bec étant éventuellement susceptible de pouvoir, comme on le sait, effectuer un mouvement de rotation autour de l'axe vertical X-Y. Ce corps de robinet 2 est luimême solidaire de la queue de robinet 3 par sa partie filetée 4. Le dispositif anti-rotation, désigné dans son ensemble par la référence A, (et qui sera décrit plus en détail ci-après en se référant aux figures 2 à 4) est inséré entre ledit corps 2 et le support de robinetterie 5, la rondelle 6 et l'écrou 7 servant de moyens de maintien en position et de fixation dudit dispositif A. Referring to these figures, the taps illustrated in FIG. 1 include an angled spout 1 inserted in the valve body 2, this spout being possibly capable, as is known, of carrying out a rotational movement around the vertical axis. XY. This valve body 2 is itself secured to the valve stem 3 by its threaded part 4. The anti-rotation device, generally designated by the reference A, (and which will be described in more detail below with reference to Figures 2 to 4) is inserted between said body 2 and the valve support 5, the washer 6 and the nut 7 serving as means for holding in position and fixing said device A.
En se référant maintenant aux figures 2 et 3, le dispositif selon l'invention comporte essentiellement un tampon 8 d'une certaine épaisseur fait en un matériau choisi parmi ceux ayant à la fois un caractère compressible et résistant avantageusement à l'agression des fluides en présence desquels il peut être mis en contact. On citera, par exemple, comme matériau approprié le caoutchouc nitrile. Referring now to Figures 2 and 3, the device according to the invention essentially comprises a pad 8 of a certain thickness made of a material chosen from those having both a compressible character and advantageously resistant to the aggression of fluids in presence of which it can be brought into contact. Mention may be made, for example, of suitable nitrile rubber.
Ce tampon 8 illustré plus en détail sur les figures 4a
4b affecte l'allure générale d'un anneau, le diamètre de sa partie centrale évidée correspondant sensiblement à celui de la queue de la robinetterie à laquelle le dispositif est destiné. Sa partie pleine comporte au moins un puits 10, destiné à recevoir une pièce faisant saillie 11 et adaptée pour pénétrer à l'intérieur d'un logement 12 réalisé dans le support 5. Par ailleurs, le tampon 8 est logé à l'intérieur d'une calotte 13 pouvant être rendue solidaire de la queue 3.This buffer 8 illustrated in more detail in Figures 4a
4b affects the general appearance of a ring, the diameter of its hollowed-out central part corresponding substantially to that of the tail of the fitting for which the device is intended. Its full part comprises at least one well 10, intended to receive a projecting part 11 and adapted to penetrate inside a housing 12 produced in the support 5. Furthermore, the pad 8 is housed inside d 'a cap 13 which can be made integral with the tail 3.
Le pourtour ou l'embase de cette calotte dite rosace 13 est garni d'une bague 14 dite bague d'identification c'est-à-dire donnant par sa couleur ou son aspect la nature du fluide circulant dans la robinetterie en cause, fluide pouvant être de l'eau potable, ou non potable, de l'air comprimé, un gaz combustible ou non, toxique ou non etc... Cette bague, lorsqu'elle est comprimée ou écrasée peut également jouer le rôle de joint d'étanchéité en plus du même rôle joué par le matériau 8 lorsque ce dernier est comprimé ou écrasé entre la calotte 13 et le support 5 par suite du serrage sur la rondelle 6 de l'écrou 7, grâce au filetage de la queue 3. La figure 2 illustre ainsi la position des pièces avant serrage alors que la figure 3 est celle correspondante, après serrage.The periphery or the base of this so-called rosette cap 13 is lined with a ring 14 known as an identification ring, that is to say giving by its color or its appearance the nature of the fluid circulating in the valve in question, fluid can be potable water, or not drinkable, compressed air, combustible gas or not, toxic or not etc ... This ring, when it is compressed or crushed can also play the role of joint of sealing in addition to the same role played by the material 8 when the latter is compressed or crushed between the cap 13 and the support 5 as a result of the tightening on the washer 6 of the nut 7, thanks to the thread of the tail 3. The figure 2 thus illustrates the position of the parts before tightening while FIG. 3 is the corresponding one, after tightening.
La mise en place du dispositif selon l'invention qui vient d'être décrit se fait de la façon suivante
Après avoir percé le trou dans le support 5 pour le passage de la queue de robinet 3 on réalise le logement 12 dans ce même support, puis on insère d'une part ladite queue 3 et d'autre part la pièce 11 chacune dans son logement respectif. On monte ensuite et fixe la rosace 13 munie du tampon 8 en veillant à ce que la pièce 11 se loge aussi dans son puits 10 et on complète le montage par l'insertion de la bague 14 puis de la rondelle 6 et de l'écrou 7 (au dessous du support 5). On procède alors au serrage de cet écrou 7 contre ledit support 5. Cette opération se traduit par l'écrasement du matériau 8 entre ce support et le corps de robinet 2 auquel la rosace a été rendue solidaire. On obtient ainsi tout d'abord une étanchéité et, d'autre part le résultat recherché c'est-à-dire que toute rotation du corps 2 sera empêchée par la présence de la pièce 11 jouant le rôle d'un ergot maintenu fortement au sein du matériau 8 et faisant corps avec lui. Du fait de son écrasement et de sa nature, ce dernier adhère également fortement au support 5 ce qui explique la raison pour laquelle la rotation du corps de robinet est entravée. Bien entendu une certaine tolérance de quelques degrés est possible.The installation of the device according to the invention which has just been described is done as follows
After having drilled the hole in the support 5 for the passage of the valve stem 3, the housing 12 is produced in this same support, then the said tail 3 is inserted on the one hand and the part 11 each in its housing. respective. Then mount and fix the rosette 13 provided with the buffer 8 ensuring that the part 11 also fits in its well 10 and the assembly is completed by the insertion of the ring 14 then the washer 6 and the nut 7 (below the support 5). This nut is then tightened against said support 5. This operation results in the crushing of the material 8 between this support and the valve body 2 to which the rosette has been made integral. A seal is thus obtained first of all, and on the other hand the desired result, that is to say that any rotation of the body 2 will be prevented by the presence of the part 11 playing the role of a lug held strongly in place. within the material 8 and being integral with it. Because of its crushing and its nature, the latter also strongly adheres to the support 5 which explains the reason why the rotation of the valve body is hampered. Of course a certain tolerance of a few degrees is possible.
Par suite de la structure des pièces constitutives du dispositif de l'invention on comprend l'intérêt qu'il y a à disposer de pièces toutes amovibles. Par ailleurs la nature du matériau 13, son montage et la place qu'il occupe dans ce dispositif font que l'effet d'étanchéité et d'adhérence obtenu se complète d'un effet d'absorption des vibrations, effet notamment apprécié lors de coups de béliers pouvant se produire dans une canalisation. As a result of the structure of the constituent parts of the device of the invention, one understands the advantage of having all removable parts. Furthermore, the nature of the material 13, its mounting and the place it occupies in this device means that the sealing and adhesion effect obtained is completed by a vibration absorption effect, an effect particularly appreciated during water hammer that can occur in a pipeline.
Les avantages obtenus grâce à ce dispositif alliés à une facilité de montage comme on l'a vu ci-dessus, ne laissent alors que peu d'importance à l'inconvénient (si cela en est un) nécessitant la percée d'un trou dans le support pour le logement de la pièce 11. The advantages obtained thanks to this device allied to an ease of assembly as we saw above, then leave little importance to the disadvantage (if that is one) requiring the drilling of a hole in the support for housing the part 11.
Il va de soi que la présente invention n'a été décrite qu'à titre purement explicatif et nullement limitatif et que toute modification utile au niveau des équivalences pourra y être apportée sans sortir de son cadre. It goes without saying that the present invention has been described for purely explanatory and in no way limitative and that any useful modification in terms of equivalences may be made without departing from its scope.
