Les
L'extrémité du robinet amont est par exemple filetée pour être raccordée à un orifice d'une bouteille 20 de fluide sous pression (cf.
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.
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
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).The circuit 3 comprises at least one
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
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
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
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 /
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 connection to the outlet fitting 8, the system is in a stable position preventing the opening of the
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
De même, le dispositif 10 de neutralisation (blocage par exemple) peut être du type mécanique et/ou magnétique et/ou pneumatique et/ou électronique.Similarly, the

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 (
Dans sa première position, l'axe 10 de verrouillage empêche le déplacement du levier 7 de commande de sa position de repos (
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
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

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

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 embodiments may be provided. For example, the locking
De même, l'axe 10 de verrouillage pourrait être remplacé par un poussoir qui actionnerait une timonerie intermédiaire (notamment avec ressort).Similarly, the locking

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
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 connection and the
