L'invention concerne en particulier un dispositif de distribution de fluide, notamment de gaz sous pression de type modulaire. L'invention concerne notamment le remplissage des bouteilles de gaz à haute pression (par exemple entre 200 et 700 bar).The invention relates in particular to a device for dispensing fluid, in particular pressurized gas of the modular type. The invention relates in particular to the filling of gas cylinders at high pressure (for example between 200 and 700 bar).

Des exemples de dispositifs de distribution de fluide modulaires sont illustrés dans les documents FR2892799A1 , FR2979687A1 , FR2970313A1 FR3022972A1 ou FR303386A1 .Examples of modular fluid dispensing devices are illustrated in the documents FR2892799A1 , FR2979687A1 , FR2970313A1 FR3022972A1 or FR303386A1 .

Pour éviter la contamination des bouteilles ou ensembles de bouteilles, il est connu de prévoir clapet de pression résiduelle au sein de la bouteille ou du robinet qui lui est attaché cf. par exemple FR303386A1 .To avoid the contamination of bottles or sets of bottles, it is known to provide residual pressure valve within the bottle or tap attached thereto cf. for example FR303386A1 .

Un tel clapet de pression résiduelle empêche classiquement la vidange totale de la bouteille en-dessous d'un seuil de pression déterminé. Ceci empêche l'intrusion d'air et d'humidité notamment lorsque la bouteille (son robinet) est maintenu(e) ouvert(e) jusqu'à sa complète vidange.Such a residual pressure valve conventionally prevents the total emptying of the bottle below a determined pressure threshold. This prevents the intrusion of air and moisture especially when the bottle (its valve) is kept open until it is completely drained.

Cette solution, bien que satisfaisante peut parfois complexifier la structure et le coût de la bouteille ou de son robinet qui lui est atttaché.et s'avérer complexe.This solution, although satisfactory, can sometimes complicate the structure and the cost of the bottle or its faucet which is attached to it and be complex.

De plus, un tel clapet de pression résiduelle logé dans la bouteille peut être soumis à des vidanges brutales (soutirage avec effet Joule-Thompson) et des remplissages rapides. Ainsi un tel clapet peut être soumis à des conditions extrêmes avec des passages de fluide dans les deux sens.In addition, such a residual pressure valve housed in the bottle can be subjected to brutal emptying (withdrawal with Joule-Thompson effect) and fast refills. Thus such a valve can be subjected to extreme conditions with fluid passages in both directions.

Un but de la présente invention est de proposer un dispositif de fourniture de fluide ayant un structure simple, compacte, une bonne ergonomie d'utilisation et une bonne sécurité vis-à-vis des pollutions possibles de l'intérieur du réservoir.An object of the present invention is to provide a fluid supply device having a simple structure, compact, good ergonomics of use and good safety vis-à-vis the possible pollution of the tank interior.

  • la figure 1 représente une vue en coupe, schématique et partielle d'un premier exemple de réalisation possible du dispositif de fourniture de fluide selon l'invention,
  • les figures 2 et 3 représentent des vues en coupe, schématiques et partielles, d'un autre exemple de réalisation possible du dispositif de fourniture de fluide et selon respectivement deux configurations ou états d'utilisation.
Other particularities and advantages will appear on reading the following description, made with reference to the figures in which:
  • the figure 1 represents a sectional view, schematic and partial of a first possible embodiment of the fluid supply device according to the invention,
  • the Figures 2 and 3 are schematic and partial sectional views of another possible embodiment of the fluid supply device and respectively two configurations or states of use.

Le dispositif 1 de fourniture de fluide sous pression illustré à la figure 1 comprend un réservoir 2 (par exemple une bouteille) de fluide sous pression muni d'un orifice dans lequel est fixé (vissage par exemple) un premier robinet 3.The device 1 for supplying fluid under pressure illustrated in FIG. figure 1 comprises a reservoir 2 (for example a bottle) of pressurized fluid provided with an orifice in which is fixed (screwing for example) a first valve 3.

Le premier robinet 3 abrite un circuit 4 interne de fluide muni d'au moins un clapet 5 de fermeture. Ce circuit 4 interne comprend par exemple une première extrémité amont en relation avec le volume de stockage du réservoir 2 et une extrémité 13 aval débouchant par exemple sur une extrémité du corps du premier robinet 3.The first valve 3 houses an internal fluid circuit 4 provided with at least one closure valve 5. This internal circuit 4 comprises for example a first upstream end in relation to the storage volume of the tank 2 and a downstream end 13 opening for example on one end of the body of the first tap 3.

Le dispositif 1 comprend en outre un second robinet 6 raccordé mécaniquement de façon séparable (amovible) sur le premier robinet 3.The device 1 further comprises a second valve 6 mechanically connected separably (detachably) to the first valve 3.

Par exemple, le premier 3 et le second robinet 6 comprennent des organes 8, 9 d'accrochage respectifs formant un système de connexion rapide amovible du second robinet 6 sur le premier robinet (cf. figures 2 et 3).For example, the first 3 and the second valve 6 comprise respective fastening members 8, 9 forming a removable quick connection system of the second valve 6 on the first valve (cf. Figures 2 and 3 ).

Le second robinet 6 comprend également un circuit interne 7 de transfert de fluide sous pression. En position raccordée du second robinet 6 sur le premier robinet 3, le circuit interne 7 du second robinet 6 est relié fluidiquement au circuit 4 interne du premier robinet 3. Par exemple, une extrémité 12 amont du circuit 7 interne du second robinet 6 est reliée à l'extrémité 13 aval du circuit 4 du premier robinet 3The second valve 6 also comprises an internal circuit 7 for transferring fluid under pressure. In the connected position of the second valve 6 on the first valve 3, the internal circuit 7 of the second valve 6 is fluidly connected to the internal circuit 4 of the first valve 3. For example, an upstream end 12 of the internal circuit 7 of the second valve 6 is connected at the downstream end 13 of the circuit 4 of the first tap 3

Le second robinet 6 comprend un organe 9 d'actionnement mobile formant de préférence un pousse-clapet destiné à ouvrir par actionnement mécanique le au moins un clapet 5 de fermeture du premier robinet 3. De plus, le second robinet 6 comprend un organe 10 de commande mobile, de préférence actionnable manuellement, prévu pour commander le déplacement de l'organe 9 d'actionnement pour commander l'ouverture ou non du clapet 5 de fermeture du premier robinet.The second valve 6 comprises a movable actuating member 9 preferably forming a valve-push for opening by mechanical actuation the at least one valve 5 for closing the first valve 3. In addition, the second valve 6 comprises a member 10 of mobile control, preferably manually operable, provided to control the movement of the actuating member 9 to control the opening or not of the valve 5 closing the first valve.

Comme illustré aux figures, l'organe 10 de commande mobile peut comprendre ou être constitué de l'un au moins parmi : un levier monté articulé sur le second robinet 6 (cf. figures 2 et 3), un bouton ou volant mobile en rotation et/ou en translation (cf. figure 1) sur le corps du robinet 6.As illustrated in the figures, the movable control member 10 may comprise or consist of at least one of: a lever mounted articulated on the second valve 6 (cf. Figures 2 and 3 ), a knob or wheel movable in rotation and / or in translation (cf. figure 1 ) on the valve body 6.

Le dispositif 1 comprend en outre un clapet 11 de pression résiduelle configuré pour empêcher la vidange complète du réservoir 2 en dessous d'un seuil de pression déterminé (par exemple compris entre 1,5 et 10 bar, notamment entre 2 et 10 bar).The device 1 further comprises a residual pressure valve 11 configured to prevent the complete emptying of the tank 2 below a determined pressure threshold (for example between 1.5 and 10 bar, in particular between 2 and 10 bar).

Selon une particularité avantageuse, le clapet 11 de pression résiduelle est situé dans le second 6 robinet. C'est-à-dire que la fonction de maintien d'une pression résiduelle est réalisée uniquement par le second robinet 6 qui vient se raccorder au premier robinet 3. Ceci permet de simplifier l'architecture du premier robinet 3 sans nuire à la protection du contenu du réservoir 2.According to an advantageous feature, the residual pressure valve 11 is located in the second valve 6. That is to say, the function of maintaining a residual pressure is performed only by the second valve 6 which is connected to the first valve 3. This simplifies the architecture of the first valve 3 without harming the protection the contents of the tank 2.

Par exemple, le circuit interne 7 du second robinet 6 comprend une extrémité amont 12 destinée à être raccordée à l'extrémité aval 13 du circuit 4 interne du premier robinet 3 et une première extrémité aval 14 débouchant au niveau d'un raccord 15 de sortie. Le raccord 15 de sortie est par exemple destiné à être raccordé fluidiquement avec un organe receveur du gaz soutiré du réservoir 2.For example, the internal circuit 7 of the second valve 6 comprises an upstream end 12 intended to be connected to the downstream end 13 of the internal circuit 4 of the first valve 3 and a first downstream end 14 opening at a outlet fitting 15. The outlet connector 15 is for example intended to be connected fluidly with a gas receiver member withdrawn from the tank 2.

Le clapet 11 de pression résiduelle est situé dans le circuit interne 7 du second robinet 6 entre l'extrémité amont 12 et l'extrémité aval 13, de préférence à proximité du raccord 15 de sortie.The residual pressure valve 11 is located in the internal circuit 7 of the second valve 6 between the upstream end 12 and the downstream end 13, preferably close to the outlet connector 15.

Comme visible aux figures 2 et 3, le clapet 11 de pression résiduelle comprend par exemple un organe 111 de fermeture mobile (piston par exemple) sollicité par un organe 211 de rappel (ressort par exemple) vers un siège dans une position de fermeture du circuit interne 7 du second robinet 6. Cet organe 211 de fermeture est soumis à l'effort du fluide sous pression dans ledit circuit 7 interne provenant de l'extrémité amont 12. Cette effort de pression tend à s'opposer à l'effort de l'organe 211 de rappel. Ainsi, selon le dimensionnement du clapet 11 de pression résiduelle, ceci empêche la sortie de fluide (clapet fermé sous l'action du ressort 211) lorsque la pression en amont est en dessous d'un seuil déterminé.As visible to Figures 2 and 3 , the residual pressure valve 11 comprises for example a movable closing member 111 (piston for example) biased by a return member 211 (spring for example) to a seat in a closed position of the internal circuit 7 of the second valve 6. This closure member 211 is subjected to the force of the fluid under pressure in said internal circuit 7 from the upstream end 12. This pressure force tends to oppose the force of the return member 211. Thus, according to the dimensioning of the residual pressure valve 11, this prevents the fluid outlet (valve closed under the action of the spring 211) when the upstream pressure is below a determined threshold.

Le clapet 11 de pression résiduelle peut intégrer par ailleurs une fonction anti-retour (« NRV » = « Non Return Valve ») empêchant l'écoulement de gaz entre l'extrémité aval 14 et l'extrémité amont 12 (empêchant ainsi un remplissage intempestif).The residual pressure valve 11 may also incorporate a non-return function ("NRV" = "Non Return Valve") preventing the flow of gas between the downstream end 14 and the upstream end 12 (thus preventing inadvertent filling ).

Comme illustré aux figures, le circuit interne 7 du second robinet 6 peut comprendre une seconde extrémité aval 16 distincte débouchant sur le corps du second robinet 6. Les deux extrémité aval 16, 14 peuvent être raccordée en parallèle à l'extrémité amont 12 du circuit 7 interne.As illustrated in the figures, the internal circuit 7 of the second valve 6 may comprise a second downstream end 16 distinct opening on the body of the second valve 6. The two downstream end 16, 14 may be connected in parallel to the upstream end 12 of the circuit 7 internally.

Cette seconde extrémité 16 aval peut être munie d'un clapet 17 de purge actionnable de préférence mécaniquement (par exemple manuellement) pour ouvrir la seconde extrémité 16 aval du circuit vers l'extérieur du second robinet 6 afin de purge ledit circuit 7 interne. Ceci permet ainsi de dépressuriser le circuit 7 interne du second robinet par exemple, avant de séparer le second robinet 6 du premier robinet 3.This second downstream end 16 may be provided with a purge valve 17 operable preferably mechanically (for example manually) to open the second downstream end 16 of the circuit to the outside of the second valve 6 to purge said internal circuit 7. This thus allows to depressurize the internal circuit 7 of the second valve for example, before separating the second valve 6 from the first valve 3.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus.Of course, the invention is not limited to the embodiment described above.

Ainsi, comme représenté aux figures 2 et 3, le circuit 4 interne du premier robinet 3 peut comprendre deux clapets 5, 17 de fermeture disposés en série.Thus, as represented in Figures 2 and 3 the internal circuit 4 of the first valve 3 may comprise two shut-off valves 5, 17 placed in series.

En position fermée, un premier 17 des clapets peut être affleurant à une extrémité du premier robinet 3.In the closed position, a first 17 of the valves may be flush with one end of the first valve 3.

L'organe 9 d'actionnement peut être mobile en translation pour former un pousse-clapet configuré pour ouvrir les clapets 17, 5 de fermeture en série par actionnement mécanique d'un premier clapet 17 de fermeture de sorte que le déplacement de ce premier clapet 17 de fermeture (déplacement dans le corps du premier robinet 3) pousse ou permet le déplacement du clapet 5 de fermeture suivant (cf. figures 2 et 3 et le document WO2012004481A1 par exemple).The actuating member 9 can be movable in translation to form a valve pushpiece configured to open the shut-off valves 17, 5 in series by mechanical actuation of a first closure valve 17 so that the movement of this first valve 17 closing (movement in the body of the first valve 3) pushes or allows the movement of the valve 5 closing next (cf. Figures 2 and 3 and the document WO2012004481A1 for example).

De même, le premier robinet 3 pourrait comporter trois clapets en série (ou plus et/ou d'autres composants). On pourra se référer par exemple à l'exemple du document WO2016139404A1 pour la séquence d'ouverture de trois clapets en série.Similarly, the first valve 3 could have three valves in series (or more and / or other components). We can refer for example to the example of the document WO2016139404A1 for the opening sequence of three valves in series.

Ainsi, lorsque le second robinet 6 (qui assure l'ouverture du ou des clapets 17, 5) est détaché du premier robinet 3, le ou les clapets 17, 5 de fermeture referment automatiquement (sous l'action d'organe(s) de rappel tels que des ressorts) le circuit 4 interne du premier robinet 3. Ainsi, une pollution ou vidange complète du réservoir 2 est évitée. Lorsque le second robinet 6 est raccordé sur le premier robinet 3 et ouvre le circuit 4 interne du premier robinet (via le déplacement du ou des clapets 17, 5) la vidange complète ou la pollution du réservoir 2 n'est pas possible même si l'utilisateur oublie de déplacer l'organe 10 de commande en position de fermeture du circuit 4 interne.Thus, when the second valve 6 (which ensures the opening of the valve or valves 17, 5) is detached from the first valve 3, the valve or valves 17, 5 closure automatically close (under the action of body (s) such as springs) the internal circuit 4 of the first valve 3. Thus, pollution or complete emptying of the tank 2 is avoided. When the second valve 6 is connected to the first valve 3 and opens the internal circuit 4 of the first valve (via the movement of the valve or valves 17, 5) complete emptying or pollution of the tank 2 is not possible even if the the user forgets to move the control member 10 in the closed position of the internal circuit 4.

Comme illustré schématiquement aux figures 2 et 3, le ou les clapets 17, 5 de fermeture peuvent comprendre un élément mobile (piston) sollicité vers un siège par un organe de rappel (ressort par exemple).As illustrated schematically in Figures 2 and 3 , or the closing valves 17, 5 may comprise a movable element (piston) biased towards a seat by a return member (spring for example).

Dans l'exemple des figures 2 et 3 l'organe 9 d'actionnement mobile comprend un axe mobile en translation. Bien entendu ceci pourrait être remplacé par tout autre système approprié.In the example of Figures 2 and 3 the movable actuating member 9 comprises a movable axis in translation. Of course this could be replaced by any other suitable system.

De même, l'invention a été décrite avec un seul réservoir 2 mais pourrait s'appliquer à un ensemble de réservoirs (cadre de bouteilles par exemple) reliés au premier robinet 3. De plus, le second robinet peut comprendre un détendeur de pression réglable ou non pour abaisser la pression du gaz à un niveau déterminé. Par exemple, le détendeur est situé dans le circuit 7 interne ou au niveau du raccord 15 de sortie.Similarly, the invention has been described with a single tank 2 but could be applied to a set of tanks (bottle frame for example) connected to the first valve 3. In addition, the second valve may comprise an adjustable pressure regulator or not to lower the gas pressure to a certain level. For example, the expander is located in the internal circuit 7 or at the outlet connector 15.
