Description

L'invention concerne un dispositif de fourniture de fluide sous pression ainsi qu'un ensemble de stockage(s) de fluide sous pression comprenant un tel dispositif.The invention relates to a pressurized fluid supply device as well as a pressurized fluid storage assembly (s) comprising such a device.

L'invention concerne plus particulièrement un dispositif de fourniture de fluide sous pression, notamment de gaz sous pression, comprenant un premier robinet abritant un circuit interne de fluide, le dispositif comportant un second robinet comprenant un circuit interne, le second robinet formant une entité physique distincte du premier robinet, le premier robinet et le second robinet comprenant des organes d'accrochages respectifs formant un système de connexion rapide male/femelle amovible du second robinet sur le premier robinet, les circuits internes comprenant un ensemble de vanne(s) pour autoriser ou empêcher la circulation du fluide vers une sortie du dispositif lorsque le second robinet est accroché sur le premier robinet via le système de connexion rapide, le dispositif comprenant au moins un organe de commande mobile actionnable manuellement pour commander l'ensemble de vanne(s), l'organe de commande étant mobile entre une première position de repos dans laquelle la circulation de fluide vers la sortie est empêchée et une seconde position active dans laquelle la circulation de fluide vers la sortie est autorisée, le système de connexion rapide comprenant un organe de verrouillage/déverrouillage du second robinet sur le premier robinet, l'organe de verrouillage/déverrouillage étant mobile entre une première position de déverrouillage lorsque la connexion rapide n'est pas établie entre le second robinet et le premier robinet ou permettant la séparation entre le second robinet et le premier robinet lorsque la connexion rapide est établie entre le second robinet et le premier robinet, et une seconde position de verrouillage empêchant la séparation entre le second robinet et le premier robinet lorsque la connexion rapide est établie entre ces derniers.The invention relates more particularly to a device for supplying pressurized fluid, in particular pressurized gas, comprising a first valve housing an internal fluid circuit, the device comprising a second valve comprising an internal circuit, the second valve forming a physical entity. separate from the first valve, the first valve and the second valve comprising respective hooking members forming a removable male / female quick connection system from the second valve to the first valve, the internal circuits comprising a set of valve (s) to allow or prevent the flow of fluid to an outlet of the device when the second valve is hooked onto the first valve via the quick-connect system, the device comprising at least one manually operable movable control member to control the valve assembly (s) , the control member being movable between a first rest position in which the circulatio n of fluid to the outlet is prevented and a second active position in which the flow of fluid to the outlet is authorized, the quick connection system comprising a member for locking / unlocking the second valve on the first valve, the locking member / unlocking being movable between a first unlocking position when the quick connection is not established between the second tap and the first tap or allowing separation between the second tap and the first tap when the quick connection is established between the second tap and the first tap, and a second locking position preventing separation between the second tap and the first tap when the quick connection is established between the latter.

L'invention concerne notamment, un dispositif modulaire de fourniture de gaz sous pression comprenant un organe de régulation de fluide tel qu'un robinet nomade qui se raccorde de façon amovible sur une base telle qu'un premier robinet solidaire d'une bouteille de gaz sous pression.The invention relates in particular to a modular device for supplying pressurized gas comprising a fluid regulation member such as a nomadic valve which is removably connected to a base such as a first valve secured to a gas cylinder. under pressure.

L'invention peut concerner notamment une architecteur telle que décrite par exemple dans le document FR3054290A1 ou FR3054291A1 .The invention may relate in particular to an architect as described for example in the document FR3054290A1 or FR3054291A1 .

Dans les dispositifs connus, dans certaines situations il peut être possible d'essayer de séparer les deux éléments raccordés (typiquement les deux robinets) lorsque le circuit de gaz est ouvert.In known devices, in certain situations it may be possible to try to separate the two connected elements (typically the two taps) when the gas circuit is open.

Dans cette situation, si l'ensemble est sous haute pression cela peut détériorer le dispositif, provoquer des fuites et une possible éjection du second robinet. Si l'ensemble est sous pression relativement basse cela peut provoquer des fuites de gaz pendant la déconnexion.In this situation, if the assembly is under high pressure, this can damage the device, cause leaks and possible ejection of the second valve. If the assembly is under relatively low pressure this can cause gas leaks during disconnection.

Des solutions sont connues pour résoudre ce problème : cf. par exemple FR2970313 A1 . Ces solutions sont ergonomiquement satisfaisantes mais peuvent induire des efforts très importants sur l'organe de commande (levier) ou permettre une déconnexion sans vraiment garantir une fermeture du circuit.Solutions are known to solve this problem: cf. for example FR2970313 A1 . These solutions are ergonomically satisfactory but can induce very significant forces on the control member (lever) or allow disconnection without really guaranteeing closure of the circuit.

La [Fig. 1] représente un dispositif 1 de fourniture de fluide sous pression, notamment de gaz sous pression, comprenant un premier robinet 3 monté dans l'orifice d'un réservoir 2 et entouré d'un chapeau 17 de protection. Bien entendu, ce premier robinet 3 pourrait être relié à un ensemble de bouteilles (cadre de bouteilles par exemple).The [ Fig. 1 ] shows a device 1 for supplying pressurized fluid, in particular pressurized gas, comprising a first valve 3 mounted in the orifice of a reservoir 2 and surrounded by a protective cap 17. Of course, this first tap 3 could be connected to a set of bottles (frame of bottles for example).

Le premier robinet 3 abrite un circuit 13 interne de fluide muni d'au moins d'un organe 4 d'isolation permettant d'ouvrir ou de fermer le circuit 13 interne. L'organe 4 d'isolement est par exemple un clapet d'isolation.The first valve 3 houses an internal fluid circuit 13 provided with at least one isolation member 4 making it possible to open or close the internal circuit 13. The isolation member 4 is for example an isolation valve.

Le dispositif 1 comprend un second robinet 5 formant une entité physique distincte (séparable) du premier robinet 3 (et en position déconnectée à la [Fig. 1] et en position partiellement connectée/accroché à la [Fig. 3] et en position correctement connectée/accroché à la [Fig. 2]).The device 1 comprises a second valve 5 forming a separate physical entity (separable) from the first valve 3 (and in the disconnected position at the [ Fig. 1 ] and in the partially connected / hooked position to the [ Fig. 3 ] and in the correctly connected / hooked position to the [ Fig. 2 ]).

Le second robinet 5 est muni d'un circuit 15 interne de fluide comprenant une première extrémité amont destinée à venir se raccorder fluidiquement à une extrémité aval 12 du circuit 13 interne du premier 3 robinet. Les deux robinets 3, 5 sont configurés pour mettre en communication leurs circuits internes 13, 15 lorsque le second robinet 5 est correctement accroché sur le premier robinet 3 via le système de connexion rapide.The second valve 5 is provided with an internal fluid circuit 15 comprising a first upstream end intended to be fluidly connected to a downstream end 12 of the internal circuit 13 of the first valve 3. The two taps 3, 5 are configured to put their internal circuits 13, 15 in communication when the second tap 5 is correctly hooked onto the first tap 3 via the quick connection system.

Le circuit 13 interne du second robinet 5 peut comprendre, par exemple, au moins un organe 9 de contrôle du flux de fluide (par exemple une vanne et/ou un détendeur fixe ou réglable et/ou un régulateur de débit). Le second 5 robinet comprend de préférence également un organe 16 mobile d'actionnement de l'organe 4 d'isolation du premier robinet 3 pour commander l'ouverture ou la fermeture de ce dernier. Par exemple, l'organe 16 mobile d'actionnement comprend un pousse-clapet mobile dont le déplacement (par exemple translation) est commandé par un organe 11 de commande manuel porté par le second 5 robinet. L'organe 11 de commande comprend un levier 11 dans cet exemple mais pourrait comprendre un bouton poussoir, un volant ou tout autre organe approprié. Le levier 11 peut commander le cas échéant l'organe 9 de contrôle du flux de fluide.The internal circuit 13 of the second valve 5 can comprise, for example, at least one member 9 for controlling the flow of fluid (for example a valve and / or a fixed or adjustable pressure reducer and / or a flow regulator). The second valve 5 preferably also comprises a movable member 16 for actuating the member 4 for isolating the first valve 3 in order to control the opening or closing of the latter. For example, the movable actuating member 16 comprises a movable valve pusher whose movement (for example translation) is controlled by a manual control member 11 carried by the second valve. The control member 11 comprises a lever 11 in this example but could comprise a push button, a steering wheel or any other suitable member. The lever 11 can, if necessary, control the member 9 for controlling the flow of fluid.

Le premier 3 robinet et le second 5 robinet comprenant des organes 6, 7 d'accrochages respectifs formant un système de connexion/accrochage rapide mâle/femelle amovible du second robinet 5 sur le premier 3 robinet.The first 3 tap and the second 5 tap comprising respective hooking members 6, 7 forming a removable male / female quick connection / hooking system from the second tap 5 on the first tap 3.

Par exemple, le premier 3 robinet comprend une extrémité terminale de forme cylindrique s'étendant selon un axe A longitudinal central sur laquelle se raccorde le second robinet 5. Le système de connexion rapide peut comprendre au moins une gorge 7 ou nervure formée sur l'extrémité cylindrique du premier robinet 3 et un système a griffes 6, billes (ou tout élément d'accrochage équivalent approprié) solidaire du second robinet 5.For example, the first valve 3 comprises a terminal end of cylindrical shape extending along a central longitudinal axis A to which the second valve 5 is connected. The quick connection system can comprise at least one groove 7 or rib formed on the cylindrical end of the first valve 3 and a claw system 6, balls (or any equivalent suitable attachment element) secured to the second valve 5.

Le ou les éléments 6 d'accrochage du second robinet 5 sont de préférence mobiles et peuvent être verrouillés/déverrouillés par exemple par un organe 14 de verrouillage/déverrouillage mobile sur le second robinet 5 (cf. [Fig. 2] et [Fig. 3]). Le ou les éléments 6 d'accrochage du second robinet 5 coopèrent avec le au moins une gorge ou nervure 7 formée sur l'extrémité cylindrique du premier robinet 3.The attachment element (s) 6 of the second valve 5 are preferably movable and can be locked / unlocked for example by a locking / unlocking member 14 movable on the second valve 5 (cf. [ Fig. 2 ] and [ Fig. 3 ]). The attachment element or elements 6 of the second valve 5 cooperate with the at least one groove or rib 7 formed on the cylindrical end of the first valve 3.

Le levier 11 est déplaçable entre une première position de repos dans laquelle la circulation de fluide vers la sortie 25 est empêchée (cf. par exemple la position basse du levier 11 de la [Fig. 1] ou la position en pointillés de la [Fig. 2] ou de la [Fig. 3]) et une seconde position active dans laquelle la circulation de fluide vers la sortie 25 est autorisée (cf. position la position relevée de la [Fig. 3]).The lever 11 is movable between a first rest position in which the flow of fluid to the outlet 25 is prevented (cf. for example the low position of the lever 11 of the [ Fig. 1 ] or the dotted position of the [ Fig. 2 ] or [ Fig. 3 ]) and a second active position in which the flow of fluid to outlet 25 is authorized (see position the raised position of [ Fig. 3 ]).

L'organe 14 de verrouillage/déverrouillage est mobile entre une première position lorsque la connexion rapide n'est pas établie entre le second robinet 5 et le premier robinet (cf. [Fig. 1] ou [Fig. 3]) et une seconde position lorsque la connexion rapide est établie entre le second robinet 5 et le premier robinet 3 (cf. [Fig. 2]).The locking / unlocking member 14 is movable between a first position when the rapid connection is not established between the second valve 5 and the first valve (cf. [ Fig. 1 ] or [ Fig. 3 ]) and a second position when the quick connection is established between the second valve 5 and the first valve 3 (cf. [ Fig. 2 ]).

Par exemple, cet organe 14 de verrouillage/déverrouillage permet ou non, selon sa position, le mouvement des organes 6 d'accrochage mobiles (et donc une connexion/déconnexion mécanique). En particulier, dans sa seconde position, l'organe 14 de verrouillage/déverrouillage ne permet pas le mouvement des organes 6 d'accrochage mobiles (blocage/verrouillage en position de connexion mécanique).For example, this locking / unlocking member 14 allows or not, depending on its position, the movement of the mobile hooking members 6 (and therefore a mechanical connection / disconnection). In particular, in its second position, the locking / unlocking member 14 does not allow movement of the movable hooking members 6 (locking / locking in the mechanical connection position).

Cet organe 14 de verrouillage/déverrouillage est donc un indicateur entre d'une part une connexion correcte (par exemple verrouillée) et, d'autre part, une absence de connexion ou une connexion incorrect ou incomplète (pas de connexion mécanique ou une connexion incomplète non verrouillée).This locking / unlocking member 14 is therefore an indicator between, on the one hand, a correct connection (for example locked) and, on the other hand, an absence of connection or an incorrect or incomplete connection (no mechanical connection or an incomplete connection. not locked).

Selon une particularité avantageuse, dans sa seconde position active, le levier 11 de commande assure un blocage de l'organe 14 de verrouillage/déverrouillage dans sa seconde position, pour empêcher la séparation entre le second robinet 5 et le premier 3 robinet (cf. cadenas fermé et flèche barrée à la [Fig. 2]).According to an advantageous feature, in its second active position, the control lever 11 locks the locking / unlocking member 14 in its second position, to prevent separation between the second valve 5 and the first valve 3 (cf. closed padlock and crossed arrow at the [ Fig. 2 ]).

De plus, dans sa première position de repos, le levier 11 ne bloque pas l'organe 14 de verrouillage/déverrouillage dans sa seconde position, pour permettre son déplacement vers sa première position et ainsi autoriser la séparation entre le second robinet 5 et le premier 3 robinet (cf. cadenas ouvert et flèche non barrée à la [Fig. 3]).In addition, in its first rest position, the lever 11 does not block the locking / unlocking member 14 in its second position, to allow its movement to its first position and thus allow the separation between the second valve 5 and the first 3 tap (see open padlock and arrow not crossed out at [ Fig. 3 ]).

Ainsi, cette architecture interdit la déconnexion du second robinet 5 par rapport au premier robinet 3 si le levier 11 est dans sa position qui commande l'ouverture du ou des circuits internes. Ce blocage est de préférence réalisé via l'organe 14 de verrouillage/déverrouillage.Thus, this architecture prevents the disconnection of the second valve 5 from the first valve 3 if the lever 11 is in its position which controls the opening of the internal circuit or circuits. This locking is preferably carried out via the locking / unlocking member 14.

Ce blocage de l'organe 14 de verrouillage/déverrouillage par le levier 11 de commande peut être directe ou indirect et de préférence mécanique mais pourrait être magnétique et/ou pneumatique ou autre.This locking of the locking / unlocking member 14 by the control lever 11 may be direct or indirect and preferably mechanical, but could be magnetic and / or pneumatic or the like.

Dans l'exemple des [Fig. 4] et [Fig. 5], l'organe 14 de verrouillage/déverrouillage peut comporter une forme 18 ou excroissance (butée par exemple). Au moins une extrémité de l'axe de rotation du levier 11 peut être est munie elle aussi d'une forme ou excroissance 19 conjuguée (par exemple en forme de palette, de bossage, de carré, de méplat, etc..).In the example of [ Fig. 4] and [Fig. 5 ], the locking / unlocking member 14 may have a shape 18 or a protuberance (stop for example). At least one end of the axis of rotation of the lever 11 may also be provided with a form or protuberance 19 (for example in the form of a pallet, a boss, a square, a flat, etc.).

En position raccordée et verrouillée (organe 14 de verrouillage/déverrouillage par exemple en position basse), si le levier 11 est dans sa seconde position active (par exemple relevée), une portion 18 de l'organe 14 de verrouillage/déverrouillage est en butée contre l'excroissance 19 de l'axe du levier 11 (cf. [Fig. 6]). Ceci interdit le déplacement de l'organe 14 de verrouillage/déverrouillage (par exemple vers le haut) et donc interdit la séparation des deux modules 3, 5.In the connected and locked position (locking / unlocking member 14 for example in the down position), if the lever 11 is in its second active position (for example raised), a portion 18 of the locking / unlocking member 14 is in abutment against the protuberance 19 of the axis of the lever 11 (cf. [ Fig. 6 ]). This prevents the movement of the locking / unlocking member 14 (for example upwards) and therefore prevents the separation of the two modules 3, 5.

Si le levier 11 est dans sa première position de repos (par exemple abaissée), l'excroissance 19 de l'axe de rotation du levier 11 se décale par rotation par exemple vers le haut et libère l'organe 14 de verrouillage/déverrouillage. Ceci autorise le déplacement l'organe 14 de verrouillage/déverrouillage vers sa première position (par exemple vers le haut) et permet donc la séparation des deux modules 3, 5.If the lever 11 is in its first rest position (for example lowered), the protuberance 19 of the axis of rotation of the lever 11 shifts by rotation, for example upwards and releases the locking / unlocking member 14. This allows the locking / unlocking member 14 to move towards its first position (for example upwards) and therefore allows the separation of the two modules 3, 5.

Dans l'exemple des [Fig. 6], [Fig. 7] et [Fig. 8], l'organe 14 de verrouillage/déverrouillage est muni d'une forme 18 ou excroissance (butée tel qu'un rebord). Une zone du levier 11 est munie elle aussi d'une forme ou excroissance 20 (palette et/ou bossage et/ou carré et/ou méplat, etc..).In the example of [ Fig. 6 ], [ Fig. 7] and [Fig. 8 ], the locking / unlocking member 14 is provided with a shape 18 or protuberance (stop such as a flange). A zone of the lever 11 is also provided with a shape or protuberance 20 (pallet and / or boss and / or square and / or flat, etc.).

En position raccordée et verrouillée (organe 14 de verrouillage/déverrouillage par exemple en position basse), si le levier 11 est dans sa seconde position active (par exemple relevée), l'organe 14 de verrouillage/déverrouillage est en butée contre l'excroissance 20 de l'axe du levier 11 (cf. [Fig. 6] ou [Fig. 7]). Ceci interdit le déplacement de l'organe 14 de verrouillage/déverrouillage (par exemple vers le haut) et donc interdit la séparation des deux modules 3, 5.In the connected and locked position (locking / unlocking member 14 for example in the lower position), if the lever 11 is in its second active position (for example raised), the locking / unlocking member 14 is in abutment against the protuberance 20 of the lever axis 11 (cf. [ Fig. 6 ] or [ Fig. 7 ]). This prevents the movement of the locking / unlocking member 14 (for example upwards) and therefore prevents the separation of the two modules 3, 5.

Si le levier 11 est déplacé dans sa première position de repos (par exemple abaissée), l'excroissance 20 du levier 11 se décale par rotation et libère l'organe 14 de verrouillage/déverrouillage. Ceci autorise le déplacement l'organe 14 de verrouillage/déverrouillage vers sa première position (par exemple vers le haut) et permet donc la séparation des deux modules 3, 5.If the lever 11 is moved into its first rest position (for example lowered), the protuberance 20 of the lever 11 shifts by rotation and releases the locking / unlocking member 14. This allows the locking / unlocking member 14 to move towards its first position (for example upwards) and therefore allows the separation of the two modules 3, 5.

Dans l'exemple des [Fig. 9] et [Fig. 10], l'organe 14 de verrouillage/déverrouillage est muni d'une zone 18 ou portion active, par exemple profilée en pente (de type came notamment).In the example of [ Fig. 9] and [Fig. 10 ], the locking / unlocking member 14 is provided with a zone 18 or active portion, for example profiled on a slope (of the cam type in particular).

En position raccordée et verrouillée (organe 14 de verrouillage/déverrouillage par exemple en position basse), si le levier 11 est dans sa seconde position active (par exemple position haute relevée), une face du levier 11 (une face d'une came du levier 11 par exemple) vient pousser une goupille 21 qui peut être libre en translation dans son support.In the connected and locked position (locking / unlocking member 14, for example in the low position), if the lever 11 is in its second active position (for example, the high raised position), one face of the lever 11 (one face of a cam of the lever 11 for example) pushes a pin 21 which can be free in translation in its support.

Cette goupille 21 se positionne par exemple sur une partie basse de la zone 18 active de l'organe 14 de verrouillage/déverrouillage cf. [Fig. 9]. Cette configuration forme une butée qui interdit le déplacement de l'organe 14 de verrouillage/déverrouillage (par exemple vers le haut) et donc interdit la séparation des deux modules 3, 5.This pin 21 is positioned for example on a lower part of the active zone 18 of the locking / unlocking member 14 cf. [ Fig. 9 ]. This configuration forms a stop which prevents the movement of the locking / unlocking member 14 (for example upwards) and therefore prevents the separation of the two modules 3, 5.

Si le levier 11 est déplacé dans sa première position de repos (par exemple abaissée), la came du levier 11 ne vient plus pousser la goupille 21 libre en translation dans son logement. En cas de translation de l'organe 14 de verrouillage/déverrouillage vers sa première position de déverrouillage, la zone 18 active peut pousser la goupille 21 (sens inverse) sans contrainte. L'organe 14 de verrouillage/déverrouillage est donc déplaçable pour permettre la séparation des deux modules 3, 5. Dans une alternative la goupille 21 (ou pion) peut être contrainte par un organe de rappel tel qu'un ressort vers une position escamotée libérant l'organe 14 de verrouillage/déverrouillage.If the lever 11 is moved to its first rest position (for example lowered), the cam of the lever 11 no longer pushes the pin 21 free in translation in its housing. In the event of translation of the locking / unlocking member 14 towards its first unlocking position, the active zone 18 can push the pin 21 (reverse direction) without constraint. The locking / unlocking member 14 is therefore movable to allow the separation of the two modules 3, 5. In an alternative, the pin 21 (or pin) can be forced by a return member such as a spring towards a retracted position releasing the locking / unlocking member 14.

Dans les exemples ci-dessus le mécanisme de blocage escamotable agit sur l'organe 14 de verrouillage/déverrouillage. Bien entendu, en variante ou en combinaison il pourrait agir sur un des organes 6, 7 d'accrochage de la connexion rapide.In the above examples, the retractable locking mechanism acts on the locking / unlocking member 14. Of course, as a variant or in combination, it could act on one of the fastening members 6, 7 of the quick connection.

En outre, le même principe et tout ou partie des exemples ci-dessus peuvent être utilisés de façon analogue pour interdire la connexion du second robinet 5 sur le premier robinet 3 si le levier 11 est dans sa seconde position active. C'est-à-dire que le levier 11 bloque dans ce cas l'organe 14 de verrouillage/déverrouillage et l'empêche de se déplacer dans seconde position de verrouillage si le levier 11 est en position active. Le raccordement mécanique verrouillé de deux robinets 3, 5 n'est pas possible tant que le levier 11 n'est pas en position de repos.In addition, the same principle and all or part of the above examples can be used in a similar fashion to prevent the connection of the second valve 5 to the first valve 3 if the lever 11 is in its second active position. That is to say that the lever 11 blocks in this case the locking / unlocking member 14 and prevents it from moving into the second locking position if the lever 11 is in the active position. The locked mechanical connection of two taps 3, 5 is not possible as long as the lever 11 is not in the rest position.

De même, le dispositif peut comporter la particularité suivante : lorsque l'organe 14 de verrouillage/déverrouillage est dans sa (première) position de non verrouillage de la connexion rapide entre les deux robinets (connexion rapide non établie ou non verrouillée), cet organe 14 de verrouillage/déverrouillage assure un blocage (direct ou indirect) du levier 11 dans sa première position de repos pour empêcher son déplacement vers sa seconde position active d'ouverture du circuit. De plus, dans sa (seconde) position de verrouillage de la connexion rapide entre les deux robinets (connexion rapide établie et verrouillée), cet organe 14 de verrouillage/déverrouillage ne bloque pas dans ce cas le levier 11 dans sa première position de repos pour autoriser son déplacement vers sa seconde position active d'ouverture du circuit. Ceci permet une sécurité supplémentaire : impossibilité d'ouvrir les circuits tant que les deux robinets ne sont pas correctement raccordés mécaniquement.Likewise, the device may have the following feature: when the locking / unlocking member 14 is in its (first) non-locking position for the quick connection between the two taps (quick connection not established or not locked), this member 14 locking / unlocking ensures a locking (direct or indirect) of the lever 11 in its first rest position to prevent its displacement to its second active position for opening the circuit. In addition, in its (second) locking position of the quick connection between the two taps (quick connection established and locked), this locking / unlocking member 14 does not in this case block the lever 11 in its first rest position for allow it to move to its second active circuit opening position. This provides additional security: it is impossible to open the circuits as long as the two taps are not correctly connected mechanically.
