Pour résoudre ce problème, le document FR2793297A1 décrit une structure de levier à double action qui permet de limiter le risque d'ouverture involontaire ou intempestive.To resolve this problem, the document FR2793297A1 describes a double action lever structure that limits the risk of involuntary or untimely opening.

Les figures 1 à 4 illustrent de façon schématique et simplifiée un robinet 1 pour fluide sous pression, avec ou sans détendeur de pression intégré, comprenant un corps 2 abritant un circuit 3 de fluide ayant une extrémité 4 amont destinée à être mise en relation avec une réserve de fluide sous pression.The figures 1 to 4 illustrate schematically and in a simplified manner a valve 1 for pressurized fluid, with or without integrated pressure regulator, comprising a body 2 housing a fluid circuit 3 having an upstream end 4 intended to be connected with a reserve of pressurized fluid .

L'extrémité du robinet amont est par exemple filetée pour être raccordée à un orifice d'une bouteille 20 de fluide sous pression (cf. figure 4) ou un circuit de gaz d'un ensemble de bouteille de gaz (cadre).The end of the upstream valve is for example threaded to be connected to an orifice of a bottle 20 of pressurized fluid (cf. figure 4 ) or a gas circuit of a gas cylinder assembly (frame).

Le circuit 3 du robinet 1 comprend une extrémité 5 aval destinée à être mise en relation avec un appareil 21 utilisateur au niveau d'un raccord 8 de sortie (cf. figures 6 et 7). L'appareil utilisateur peut être raccordé au raccord 8 de sortie via une flexible, un détendeur de pression, un régulateur de débit ou tout autre appareil approprié.The circuit 3 of the valve 1 comprises a downstream end 5 intended to be put in connection with a user device 21 at the level of an outlet connector 8 (cf. figures 6 and 7 ). The user device can be connected to the outlet connection 8 via a hose, a pressure regulator, a flow regulator or any other suitable device.

Le raccord 8 de sortie peut être du type mâle ou femelle, fileté, taraudé ou peut comprendre tout type de raccord mécanique et fluidique approprié (par exemple une liaison à connexion rapide).The outlet connector 8 may be of the male or female type, threaded, tapped or may comprise any type of suitable mechanical and fluidic connection (for example a quick-connect connection).

Le circuit 3 comprend au moins un organe 6 de contrôle du débit dans le circuit 3 tel qu'une vanne ou clapet, notamment un clapet d'isolation (par exemple auto-obturant).Circuit 3 comprises at least one member 6 for controlling the flow rate in circuit 3, such as a valve or valve, in particular an isolation valve (for example self-sealing).

L'organe 6 de contrôle du débit est commandé par un mécanisme de commande comprenant un organe 7 de commande mobile actionnable manuellement et/ou automatique.The flow control member 6 is controlled by a control mechanism comprising a movable control member 7 which can be manually and / or automatically actuated.

L'organe 7 de commande est monté mobile sur le corps 2 du robinet 1 (rotation et/ou translation par exemple) entre une position de repos dans laquelle l'organe 6 de contrôle du débit est maintenu dans un premier état correspondant à une première valeur de débit dans le circuit 3 (par exemple un débit nul correspondant à un circuit fermé) et une seconde position active dans laquelle l'organe 7 de commande déplace l'organe 6 de contrôle du débit dans un second état correspondant à une seconde valeur de débit dans le circuit 3 (par exemple débit maximal correspondant à un circuit 3 ouvert).The control member 7 is movably mounted on the body 2 of the valve 1 (rotation and / or translation for example) between a rest position in which the flow control member 6 is maintained in a first state corresponding to a first flow rate value in circuit 3 (for example a zero flow corresponding to a closed circuit) and a second active position in which the control member 7 moves the flow control member 6 into a second state corresponding to a second value flow rate in circuit 3 (for example maximum flow rate corresponding to an open circuit 3).

Selon une particularité avantageuse, le robinet 1 comprend un organe 9 détecteur de raccordement situé au niveau du raccord 8 de sortie ou de façon adjacente au raccord 8 de sortie et configuré pour détecter une liaison, notamment mécanique et/ou fluidique au niveau du raccord 8 de sortie. Le robinet 1 comprend en outre un dispositif 10 de neutralisation du mécanisme 7, 14 de commande relié à l'organe 9 détecteur de raccordement et configuré pour empêcher le passage de l'organe 6 de contrôle du débit de son premier vers son second état tant que l'organe 9 détecteur de raccordement ne détecte pas une liaison (par exemple mécanique) au niveau du raccord 8 de sortie.According to an advantageous feature, the valve 1 comprises a connection detector member 9 located at the level of the outlet connector 8 or adjacent to the outlet connector 8 and configured to detect a connection, in particular mechanical and / or fluidic at the level of the connector 8 Release. Tap 1 includes furthermore a device 10 for neutralizing the control mechanism 7, 14 connected to the connection detector member 9 and configured to prevent the passage of the flow control member 6 from its first to its second state as long as the member 9 connection detector does not detect a connection (eg mechanical) at the outlet connection 8.

C'est-à-dire que l'ouverture de la vanne/clapet 6 est automatiquement interdite s'il n'est pas détecté de raccordement au niveau du raccord 8 de sortie. De même, l'ouverture de la vanne/clapet 6 est automatiquement autorisée s'il est détecté de raccordement au niveau du raccord 8 de sortie.That is to say that the opening of the valve / flap 6 is automatically prohibited if no connection is detected at the outlet connection 8. Likewise, the opening of the valve / flap 6 is automatically authorized if a connection is detected at the outlet connection 8.

Ainsi, en absence de branchement sur le raccord 8 de sortie, le système est en position stable empêchant l'ouverture de la vanne 6. Le branchement d'une installation au niveau du raccord 8 de sortie du robinet 1 vient débloquer ou rendre opérationnel le robinet 1 pour permettre la libération du fluide sous pression. La position permettant l'ouverture du flux de gaz peut être stable ou non.Thus, in the absence of a connection to the outlet fitting 8, the system is in a stable position preventing the opening of the valve 6. The connection of an installation at the level of the outlet fitting 8 of the tap 1 unblocks or makes the valve operational. valve 1 to allow the release of the pressurized fluid. The position allowing the opening of the gas flow may or may not be stable.

L'organe 9 détecteur de raccordement peut comprendre au moins l'un parmi : un détecteur mécanique, un détecteur magnétique (RFID, NFC ou autre), un détecteur pneumatique, un détecteur électronique.The connection detector unit 9 can comprise at least one of: a mechanical detector, a magnetic detector (RFID, NFC or other), a pneumatic detector, an electronic detector.

De même, le dispositif 10 de neutralisation (blocage par exemple) peut être du type mécanique et/ou magnétique et/ou pneumatique et/ou électronique.Likewise, the neutralization device 10 (blocking for example) may be of the mechanical and / or magnetic and / or pneumatic and / or electronic type.

Dans l'exemple illustré à la figure 1 le dispositif 10 de neutralisation peut agir directement ou indirectement sur l'organe 7 de commande.In the example shown in figure 1 the neutralization device 10 can act directly or indirectly on the control member 7.

Dans l'exemple illustré à la figure 2 le dispositif 10 de neutralisation peut agir directement ou indirectement sur le mécanisme 14 de commande, c'est-à-dire sur au moins une pièce de transmission de mouvement ou d'effort interposée entre l'organe 7 de commande et la vanne 6.In the example shown in figure 2 the neutralization device 10 can act directly or indirectly on the control mechanism 14, that is to say on at least one movement or force transmission part interposed between the control member 7 and the valve 6.

Dans l'exemple illustré aux figures 3 et 4 le dispositif 10 de neutralisation peut agir directement ou indirectement sur la vanne ou clapet 6.In the example shown in figures 3 and 4 the neutralization device 10 can act directly or indirectly on the valve or valve 6.

Dans l'exemple illustré à la figure 3, l'organe 9 détecteur de raccordement est situé sur la périphérie du raccord 8 de sortie.In the example shown in figure 3 , the connection detector unit 9 is located on the periphery of the outlet connection 8.

Dans l'exemple illustré à la figure 4, l'organe 9 détecteur de raccordement est situé dans le raccord 8 de sortie, par exemple en dehors du circuit 3 (ou dans le circuit dans lequel circule le fluide cf. figure 19).In the example shown in figure 4 , the connection detector unit 9 is located in the outlet connection 8, for example outside the circuit 3 (or in the circuit in which the fluid circulates cf. figure 19 ).

Dans l'exemple de réalisation des figures 5 à 7, l'organe de commande est un levier 7 articulé sur le corps 2 et mobile entre une première position (par exemple abaissée (le long du corps 2 cf. figure 5 et 6) et une seconde position (par exemple relevée et écartée du corps 2 cf. figure 7).In the example of realization of figures 5 to 7 , the control member is a lever 7 articulated on the body 2 and movable between a first position (for example lowered (along the body 2 cf. figure 5 and 6 ) and a second position (for example raised and removed from the body 2 cf. figure 7 ).

Le dispositif de neutralisation comprend dans cet exemple un axe 10 de verrouillage du levier 7. L'axe 10 de verrouillage est monté mobile dans le corps 2 du robinet 1 entre une première position (figure 5) et une seconde position (figures 6 et 7). Par exemple l'axe 10 de verrouillage est mobile en translation transversalement à l'axe vertical du corps du robinet 1.The neutralization device comprises in this example a pin 10 for locking the lever 7. The locking pin 10 is movably mounted in the body 2 of the valve 1 between a first position ( figure 5 ) and a second position ( figures 6 and 7 ). For example the locking axis 10 is movable in translation transversely to the vertical axis of the valve body 1.

Dans sa première position, l'axe 10 de verrouillage empêche le déplacement du levier 7 de commande de sa position de repos (figure 5) vers sa position active (figure 7). Par exemple, une portion 11 en forme de crochet de l'axe 10 de verrouillage forme une butée de blocage de l'organe 7 de commande lorsque l'axe 10 de verrouillage est dans sa première position (cf. figure 5).In its first position, the locking pin 10 prevents the movement of the control lever 7 from its rest position ( figure 5 ) to its active position ( figure 7 ). For example, a hook-shaped portion 11 of the locking pin 10 forms a locking stop for the control member 7 when the locking pin 10 is in its first position (cf. figure 5 ).

Dans sa seconde position, l'axe 10 de verrouillage autorise au contraire le déplacement du levier 7 entre ses positions de repos et active. Par exemple, l'organe 9 détecteur de raccordement coopère avec l'axe 10 de verrouillage pour déplacer ce dernier de sa première position vers sa seconde position lorsqu'un raccordement 21 est détecté au niveau du raccord 8 de sortie.In its second position, the locking pin 10 allows on the contrary the movement of the lever 7 between its rest and active positions. For example, the connection detector member 9 cooperates with the locking pin 10 to move the latter from its first position to its second position when a connection 21 is detected at the outlet connector 8.

Par exemple, une extrémité amont de l'axe 10 de verrouillage peut comporter ou constituer l'organe 9 détecteur de raccordement. Cette extrémité de l'axe 10 de verrouillage peut faire saillie dans ou de façon adjacente au raccord 8 de sorte que cette extrémité est poussée par un appareil 21 utilisateur venant se raccorder niveau du raccord 8. Ceci déplace automatiquement l'axe 10 de verrouillage de sa première position vers sa seconde position.For example, an upstream end of the locking pin 10 may include or constitute the connection detector member 9. This end of the locking pin 10 may protrude into or adjacent to the fitting 8 so that this end is pushed by a user device 21 coming to connect at the fitting 8. This automatically moves the locking pin 10 out of the way. its first position to its second position.

Comme schématisé à la figure 5, le robinet comprend de préférence un organe 15 de rappel sollicitant l'axe 10 de verrouillage vers sa première position.As shown schematically at figure 5 , the valve preferably comprises a return member 15 urging the locking pin 10 towards its first position.

Dans les variantes de réalisation des figures 8 à 11, l'axe 10 de verrouillage comporte une portion 101 de butée qui est reçue (figure 8 ou 10) ou non (figure 9 ou 11) dans un logement 17 complémentaire du levier 7.In the alternative embodiments of figures 8 to 11 , the locking pin 10 comprises a stop portion 101 which is received ( figure 8 or 10 ) or not ( figure 9 or 11 ) in a housing 17 complementary to the lever 7.

Dans sa première position, l'axe 10 de verrouillage vient par exemple s'emboîter dans le levier 7 pour bloquer sa rotation. Dans sa seconde position le levier 7 est en revanche libre de pivoter. A cet effet, l'axe 10 de verrouillage possède au moins un épaulement ou découpe réalisant cette fonction de blocage mécanique ou de libération selon sa position par rapport au levier 7.In its first position, the locking pin 10 for example engages in the lever 7 to block its rotation. In its second position, the lever 7 is however free to pivot. For this purpose, the locking pin 10 has at least one shoulder or cutout performing this function of mechanical locking or release depending on its position with respect to the lever 7.

Comme schématisé aux figures 8 et 9, le levier 7 peut comporter une came prévue pour coopérer avec un axe 14 de transmission de mouvement actionnant directement ou indirectement le clapet 6. C'est-à-dire que le mouvement de rotation du levier 7 est transformé en mouvement de translation de l'axe 14 de transmission.As shown in figures 8 and 9 , the lever 7 may include a cam provided to cooperate with a movement transmission axis 14 directly or indirectly actuating the valve 6. That is to say that the rotational movement of the lever 7 is transformed into a translational movement of the 'axis 14 of transmission.

La variante de réalisation des figures 12 à 15 se distingue de celle des figures 8 à 11 en ce que l'axe 10 de verrouillage comporte une portion 101 de butée qui est reçue (figures 12 et 14) ou non (figures 13 et 15) dans un logement 140 complémentaire de l'axe 14 de transmission. Ceci permet également de bloquer (figures 12 et 14) ou de débloquer le mécanisme de commande.The variant of the figures 12 to 15 differs from that of figures 8 to 11 in that the locking pin 10 comprises a stop portion 101 which is received ( figures 12 and 14 ) or not ( figures 13 and 15 ) in a housing 140 complementary to the axis 14 of transmission. This also allows to block ( figures 12 and 14 ) or unlock the operating mechanism.

Bien entendu d'autres variantes de réalisation peuvent être prévues. Par exemple, l'axe 10 de verrouillage peut coopérer avec toute autre pièce mobile de transmission de mouvement ou d'effort du mécanisme de commande.Of course other variant embodiments can be provided. For example, the locking pin 10 can cooperate with any other movable part for transmitting movement or force of the control mechanism.

De même, l'axe 10 de verrouillage pourrait être remplacé par un poussoir qui actionnerait une timonerie intermédiaire (notamment avec ressort).Likewise, the locking pin 10 could be replaced by a pusher which would actuate an intermediate linkage (in particular with a spring).

Comme illustré à la figure 16, le robinet peut comporter un dispositif 16 antivol ou un sceau de garanti frangible situe sur le mécanisme 7, 14 de commande (en combinaison ou alternativement au caractéristiques ci-dessus).As shown in figure 16 , the valve may include an anti-theft device 16 or a frangible guarantee seal located on the control mechanism 7, 14 (in combination or alternatively with the above characteristics).

Ce dispositif antivol 16 ou sceau de garantie peut être monté de façon amovible par exemple et peut être remplaçable le cas échéant.This anti-theft device 16 or warranty seal can be mounted removably, for example, and can be replaced if necessary.

Par exemple le dispositif 16 antivol comprend un verrou à pêne 19 mobile actionné par une clé 18 ou autre. Par exemple, selon la position de la clé 18, le pêne 19 coopère ou non avec un logement de l'axe 10 de verrouillage.For example, the anti-theft device 16 comprises a movable bolt lock 19 actuated by a key 18 or the like. For example, depending on the position of the key 18, the bolt 19 may or may not cooperate with a housing of the locking pin 10.

Dans une variante de réalisation le raccord et l'organe 9 de détection peuvent ne former qu'un. Par exemple, l'organe 9 de détection est intégré au raccord ou défini par la structure du raccord lui-même.In an alternative embodiment, the connector and the detection member 9 may form one. For example, the detection member 9 is integrated into the connector or defined by the structure of the connector itself.
