Description

L'invention concerne un robinet pour fluide sous pression.The invention relates to a valve for pressurized fluid.

L'invention concerne plus particulièrement un robinet pour fluide sous pression, avec ou sans détendeur de pression intégré, comprenant un corps abritant un circuit de fluide ayant une extrémité amont destinée à être mise en relation avec une réserve de fluide sous pression et une extrémité aval destinée à être mise en relation avec un appareil utilisateur au niveau d'un raccord de sortie, le circuit comprenant un organe de contrôle du débit dans le circuit tel qu'une vanne ou clapet, l'organe de contrôle du débit étant commandé par un mécanisme de commande comprenant un organe de commande actionnable manuellement et monté mobile sur le corps du robinet entre une position de repos dans laquelle l'organe de contrôle du débit est maintenu dans un premier état correspondant à une première valeur de débit dans le circuit et une seconde position active dans laquelle l'organe de commande déplace l'organe de contrôle du débit dans un second état correspondant à une seconde valeur de débit dans le circuit.The invention more particularly relates to a valve for pressurized fluid, with or without an integrated pressure regulator, comprising a body housing a fluid circuit having an upstream end intended to be put in relation with a reserve of fluid under pressure and a downstream end. intended to be connected to a user device at an outlet connection, the circuit comprising a flow control member in the circuit such as a valve or valve, the flow control member being controlled by a control mechanism comprising a manually operable control member movably mounted on the valve body between a rest position in which the flow control member is held in a first state corresponding to a first flow rate value in the circuit and a second active position in which the control member moves the flow control member to a corresponding second state at a second flow rate value in the circuit.

L'invention concerne en particulier une bouteille de fluide sous pression (par exemple du gaz sous pression) ou un ensemble de bouteilles de fluide sous pression (cadre de bouteilles par exemple) raccordé(s) à un tel robinet.The invention particularly relates to a bottle of pressurized fluid (for example pressurized gas) or a set of pressurized fluid bottles (bottle frame for example) connected to such a valve.

Le robinet peut être également un robinet pour canalisation.The tap may also be a tap for piping.

Les robinets à levier pour fluides sous pression présentent un avantage ergonomique majeur par la rapidité et praticité d'ouverture-fermeture (cf. par exemple les documents EP747796A1 ou EP1421305A1 ).Lever taps for pressurized fluids have a major ergonomic advantage due to the speed and practicality of opening and closing (see eg documents EP747796A1 or EP1421305A1 ).

Toutefois, cette praticité augmente le risque d'exposition de l'utilisateur au fluide sous pression soit par ouverture accidentelle, soit par ouverture volontaire sans installation branchée au niveau du raccord de sortie.However, this convenience increases the risk of exposure of the user to the pressurized fluid either by accidental opening or by voluntary opening without installation connected to the outlet connection.

Pour résoudre ce problème, le document FR279329A1 décrit une structure de robinet à levier à double action qui permet de limiter le risque d'ouverture involontaire ou intempestive.To resolve this problem, the document FR279329A1 describes a double action lever valve structure that limits the risk of accidental or unintentional opening.

Cette solution ne résout cependant pas totalement les problèmes des situations à risque.This solution, however, does not completely solve the problems of risk situations.

Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus.An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.

A cette fin, le robinet selon l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend un organe détecteur de raccordement situé au niveau du raccord de sortie ou de façon adjacente au raccord de sortie et configuré pour détecter une liaison mécanique d'un organe utilisateur au niveau du raccord de sortie, le robinet comprenant en outre un dispositif de neutralisation du mécanisme de commande tant que l'organe détecteur de raccordement ne détecte pas une liaison mécanique au niveau du raccord de sortie, le dispositif de neutralisation étant relié à l'organe détecteur de raccordement et comprenant au moins une pièce de débrayage sollicitant l'organe de commande ou une pièce intermédiaire du mécanisme de commande dans une position neutralisée empêchant la commande du passage de l'organe de contrôle du débit de son premier vers son second état.For this purpose, the valve according to the invention, furthermore in conformity with the generic definition given in the preamble above, is essentially characterized by it comprises a connection detector member located at the outlet connection or adjacent to the outlet fitting and configured to detect a mechanical connection of a user member at the outlet connection, the valve further comprising a device for neutralizing the control mechanism as long as the connection detector element does not detect a mechanical connection at the outlet connection, the neutralization device being connected to the connection detector member and comprising at least one disengaging piece requesting the control member or an intermediate part of the control mechanism in a neutralized position preventing the control of the passage of the flow control member from its first to its second state.

Cette structure permet d'empêcher l'ouverture manuelle de la vanne en absence d'installation en sortie du robinet et donc de limiter les risques d'exposition de l'utilisateur aux hautes pressions.This structure makes it possible to prevent the manual opening of the valve in the absence of installation at the outlet of the tap and thus to limit the risks of exposure of the user to high pressures.

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 simplified a valve 1 for pressurized fluid, with or without built-in pressure reducer, comprising a body 2 housing a fluid circuit 3 having an upstream end 4 intended to be put in relation with a reserve of fluid under pressure .

L'extrémité amont du corps 2 robinet 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 upstream end of the valve body 2 is for example threaded to be connected to an orifice of a bottle 20 of fluid under pressure (cf. figure 4 ) or a gas circuit of a gas cylinder assembly (frame).

Le robinet 1 comprend une extrémité 5 aval destinée à être mise en relation avec un appareil utilisateur 21 au niveau d'un raccord 8 de sortie (cf. figures 6 et 7). L'appareil 21 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 valve 1 comprises a downstream end intended to be connected to a user device 21 at an outlet connector 8 (cf. Figures 6 and 7 ). The user apparatus 21 may be connected to the outlet connector 8 via a hose, a pressure regulator, a flow regulator, or any other suitable apparatus.

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 include any type of suitable mechanical and fluidic connection (for example a quick-connect connection).

Le circuit 3 comprend 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 a flow control member 6 in the 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 automatiquement à distance.The flow control member 6 is controlled by a control mechanism comprising a movable control member 7 operable manually and / or automatically remotely.

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). Bien entendu, des positions intermédiaires de l'organe de commande correspondant à des débits ou degrés d'ouverture intermédiaires du circuit pourraient être prévues.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 value in the 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 in a second state corresponding to a second value flow rate in the circuit 3 (for example maximum flow corresponding to an open circuit 3). Of course, intermediate positions of the control member corresponding to intermediate flow rates or degrees of opening of the circuit could be provided.

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 mécanique 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 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 outlet connector 8 or adjacent to the outlet connector 8 and configured to detect a mechanical connection at the outlet connector 8. The valve 1 further comprises 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 so that the connection detector 9 does not detect a mechanical connection 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 / valve 6 is automatically prohibited if there is no connection detected at the outlet connector 8. Similarly, the opening of the valve / valve 6 is automatically authorized if it is detected connection at the outlet connector 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 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 outlet fitting 8 of the valve 1 comes to unlock or make operational the valve 1 to allow the release of the fluid under pressure. The position allowing the opening of the gas flow can be stable or not.

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 9 may 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 peut être du type mécanique et/ou magnétique et/ou pneumatique et/ électronique.Similarly, the neutralization device 10 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 interposée entre l'organe 7 de commande et la vanne 6.In the example shown in figure 2 the device 10 for neutralization can act directly or indirectly on the control mechanism 14, that is to say on at least one piece 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 device 10 for neutralization 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 connecting detector member 9 is located on the periphery of the outlet connector 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 ou dans le circuit dans lequel circule le fluide (cf. figure 19).In the example shown in figure 4 , the connection detector 9 is located in the outlet connection 8, for example outside 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. figures 5 et 6) et une seconde position (par exemple relevée et écartée du corps 2, cf. figure 7).In the exemplary embodiment 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. Figures 5 and 6 ) and a second position (for example raised and removed from the body 2, cf. figure 7 ).

Selon une caractéristique avantageuse, le dispositif de neutralisation est relié à l'organe 9 détecteur de raccordement et comprend au moins une pièce 12, 15 de débrayage sollicitant l'organe 7 de commande ou une pièce 14 intermédiaire du mécanisme de commande dans une position neutralisée empêchant la commande du passage de l'organe 6 de contrôle du débit de son premier vers son second état.According to an advantageous characteristic, the neutralization device is connected to the connection detector element 9 and comprises at least one disengaging member 12, 15 biasing the control member 7 or an intermediate part 14 of the control mechanism in a neutralized position. preventing the control of the passage of the flow control member 6 from its first to its second state.

Dans l'exemple des figures 5 à 7, le levier 7 est déplaçable sur le corps 2 par rapport au reste du mécanisme de commande selon un mouvement de commutation distinct de son mouvement de pivotement entre ses positions de repos et active. Dans cet exemple non limitatif, le mouvement de commutation du levier 7 est un mouvement de translation, par exemple une translation parallèle à l'axe 12 de rotation du levier 7. Le mouvement de commutation permet de déplacer le levier 7 entre la position neutralisée et une position dite « fonctionnelle» permettant la commande du passage de l'organe 6 de contrôle du débit de son premier vers son second état.In the example of Figures 5 to 7 , the lever 7 is movable on the body 2 relative to the rest of the control mechanism in a switching movement distinct from its pivoting movement between its rest and active positions. In this nonlimiting example, the switching movement of the lever 7 is a translational movement, for example a translation parallel to the axis 12 of rotation of the lever 7. The switching movement moves the lever 7 between the neutralized position and a so-called "functional" position for controlling the passage of the flow control member 6 from its first to its second state.

L'organe 9 détecteur de raccordement coopère avec le levier 7 directement ou indirectement pour déplacer ce dernier de sa position neutralisée vers sa position fonctionnelle lorsqu'un raccordement est détecté au niveau du raccord 8 de sortie (cf. figures 6 et 7).The connection detector 9 cooperates with the lever 7 directly or indirectly to move the latter from its neutralized position to its functional position when a connection is detected at the outlet connection 8 (cf. Figures 6 and 7 ).

Dans le mode de réalisation des figures 5 à 7, en position neutralisée (figure 5), le levier 7 de commande est entravé par une butée 13 formée par le corps 2 du robinet 1 ou une pièce rapportée sur le corps 2 pour empêcher son pivotement entre ses position de repos et active. Par exemple, une portion du levier 7 coudé est bloquée sous une paroi 13 du corps 2 (et/ou d'une coque qui recouvre le corps 2) qui empêche le relèvement du levier 7. En revanche, dans sa position fonctionnelle décalée transversalement sur le corps 2 du robinet 1 (figures 6 et 7), le levier 7 n'est plus entravé par la butée 13 pour permettre son mouvement entre ses position de repos et active. Par exemple, en position fonctionnelle le levier 7 vient se placer dans une ouverture du corps 2 qui n'entrave pas son pivotement.In the embodiment of Figures 5 to 7 , in neutralized position ( figure 5 ), the control lever 7 is hindered by a stop 13 formed by the body 2 of the valve 1 or an insert on the body 2 to prevent its pivoting between its rest position and active. For example, a portion of the lever 7 bent is locked under a wall 13 of the body 2 (and / or a shell which covers the body 2) which prevents the raising of the lever 7. In contrast, in its functional position offset transversely on the body 2 of the tap 1 ( Figures 6 and 7 ), the lever 7 is no longer impeded by the stop 13 to allow movement between its rest position and active. For example, in the operative position the lever 7 is placed in an opening of the body 2 which does not hinder its pivoting.

Comme schématisé à la figure 5, le robinet 1 comprend de préférence un organe 15 de rappel sollicitant le levier 7 vers sa première position neutralisée.As schematized at figure 5 , the valve 1 preferably comprises a return member 15 biasing the lever 7 to its first neutralized position.

Dans la position neutralisée du levier 7 (figure 5), la liaison mécanique entre le levier 7 et le clapet 6 est interrompue tandis que dans la position fonctionnelle (figures 6 et 7), liaison mécanique entre le levier 7 de commande et l'organe 6 de contrôle du débit est assurée.In the neutralized position of lever 7 ( figure 5 ), the mechanical connection between the lever 7 and the valve 6 is interrupted while in the functional position ( Figures 6 and 7 ), mechanical connection between the control lever 7 and the flow control member 6 is ensured.

Comme schématisé aux figures 8 et 9 le levier 7 peut comporter une came prévue pour coopérer avec mécanisme comprenant 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 schematized at Figures 8 and 9 the lever 7 may comprise a cam provided to cooperate with a mechanism comprising a motion transmission shaft 14 actuating directly or indirectly the valve 6. That is to say that the rotational movement of the lever 7 is converted into translation movement of the transmission axis 14.

Comme illustré aux figures 8 et 9, le mouvement de commutation du levier 7 peut consister à disposer la came du levier 7 au niveau de l'extrémité de l'axe 14 de transmission (position fonctionnelle de la figure 9) ou à écarter (séparer) la came du levier 7 de l'axe 14 de transmission.As illustrated in Figures 8 and 9 , the switching movement of the lever 7 may consist in arranging the cam of the lever 7 at the end of the transmission shaft 14 (functional position of the figure 9 ) or to separate (separate) the cam from the lever 7 of the transmission shaft 14.

Le dispositif de neutralisation peut ainsi comprendre un épaulement du corps 2 du robinet sans lien avec l'organe de détection 9. En revanche, un organe d'activation peut être relié à l'organe 9 détecteur 9.The neutralization device may thus comprise a shoulder of the body 2 of the valve that is not connected to the detection member 9. On the other hand, an activation member may be connected to the detector member 9.

Ceci est illustré également aux figures 10 à 13. Dans les figures 10 et 11 le levier 7 est en position neutralisée écartée de l'axe 14 de transmission. Le mouvement de pivotement du levier 7 n'a aucun effet sur l'axe 14 de transmission et donc sur le clapet 6 (cf. figure 11).This is also illustrated in Figures 10 to 13 . In the Figures 10 and 11 the lever 7 is in neutralized position spaced from the axis 14 of transmission. The pivoting movement of the lever 7 has no effect on the transmission axis 14 and therefore on the valve 6 (cf. figure 11 ).

En revanche, en position fonctionnelle (came du levier 7 coopérant avec l'axe 14 de transmission), le pivotement du levier 7 déplace l'axe 14 de transmission pour actionner le clapet 6 (cf. figure 13).In contrast, in the operative position (lever cam 7 cooperating with the transmission axis 14), the pivoting of the lever 7 moves the transmission shaft 14 to actuate the valve 6 (cf. figure 13 ).

C'est-à-dire que dans son état de base le déplacement du levier7 (ou autre) est sans effet sur l'ouverture de la vanne 6. Le mécanisme 10 vient rendre ce système actif. C'est-à-dire qu'en cas de détection d'un raccordement au niveau du raccord 8 de sortie le mécanisme 10 permet l'activation de la liaison entre le levier 7 et le clapet (le mouvement du levier 7 ou autre devient efficace).That is to say that in its basic state the movement of the lever 7 (or other) has no effect on the opening of the valve 6. The mechanism 10 makes this system active. That is to say, in the event of detection of a connection at the outlet connection 8, the mechanism 10 enables activation of the connection between the lever 7 and the valve (the movement of the lever 7 or the other becomes effective).

Par exemple, le levier 7 est solidaire en rotation et en translation d'un axe 12 de rotation. Cet axe 12 de rotation du levier 7 peut formant au moins une partie du dispositif de neutralisation. Par exemple, l'axe 12 de rotation est monté mobile en translation dans le corps entre deux position extrêmes correspondant respectivement aux positions neutralisées et fonctionnelle du mouvement de commutation du levier 7. Ce déplacement de l'axe 12 de rotation est par exemple commandé par l'organe 9 de détection.For example, the lever 7 is integral in rotation and in translation with an axis 12 of rotation. This axis 12 of rotation of the lever 7 may form at least part of the neutralization device. For example, the axis 12 of rotation is mounted to move in translation in the body between two extreme positions respectively corresponding to the neutralized and functional positions of the switching movement of the lever 7. This displacement of the axis 12 of rotation is for example controlled by the detection member 9.

Dans un mode de réalisation le robinet comprend un axe 12 de commutation monté mobile dans le corps 2 et comprenant une première extrémité 9 faisant saillie dans le raccord 8 de sortie ou de façon adjacente audit raccord 8. Cette première extrémité est prévue pour être poussée par un appareil 21 utilisateur venant se raccorder niveau du raccord 8 de sortie. L'axe 12 de commutation comprend une seconde extrémité qui actionne le déplacement du levier 7 ou d'une pièce 14 intermédiaire du mécanisme de commande de sa position neutralisée vers sa position fonctionnelle.In one embodiment the valve comprises a switching shaft 12 movably mounted in the body 2 and having a first end 9 projecting into the outlet connector 8 or adjacent said connector 8. This first end is intended to be pushed by a user device 21 to be connected to the level of the outlet connector 8. The axis 12 of switching comprises a second end which actuates the movement of the lever 7 or an intermediate part 14 of the control mechanism from its neutralized position to its operative position.

Dans le mode de réalisation des figures 5 à 7, l'axe 12 de rotation peut constituer tout ou partie de l'axe de commutation.In the embodiment of Figures 5 to 7 the axis 12 of rotation may constitute all or part of the switching axis.

En variante le levier 7 (ou la came) peut être monté solidaire en rotation et mobile en translation sur l'axe 12 de rotation entre deux positions extrêmes correspondant respectivement aux positions neutralisées et fonctionnelle du mouvement de commutation du levier 7. Dans ce cas l'axe 12 de rotation reste fixe tandis que c'est le levier 7 qui est déplacé par un axe de commutation.As a variant, the lever 7 (or the cam) can be mounted fast to rotate and move in translation on the axis 12 of rotation between two extreme positions respectively corresponding to the neutralized and functional positions of the switching movement of the lever 7. In this case the 12 axis rotation remains fixed while it is the lever 7 which is moved by a switching axis.

Dans la variante des figures 14 et 15, l'organe 9 détecteur de raccordement coopère (via un axe ou une pièce 12 de commutation) avec une pièce 14 intermédiaire du mécanisme de commande située entre le levier 7 et le clapet 6. C'est-à-dire que l'organe 9 détecteur de raccordement commande (via l'axe 12 de commutation) le déplacement d'une pièce 14 intermédiaire au lieu de déplacer le levier ou sa came. Cette pièce intermédiaire peut notamment être l'axe 14 de transmission.In the variant of Figures 14 and 15 , the connection detector 9 cooperates (via an axis or a switching part 12) with an intermediate part 14 of the control mechanism located between the lever 7 and the valve 6. That is to say that the organ 9 control connection detector (via the switching axis 12) the displacement of an intermediate part 14 instead of moving the lever or its cam. This intermediate piece may in particular be the transmission axis 14.

Bien entendu d'autres variantes de réalisation peuvent être prévues. Par exemple, l'axe 12 de commutation peut être remplacé par un poussoir ou autre qui actionnerait une timonerie intermédiaire (notamment avec ressort).Of course other embodiments may be provided. For example, the axis 12 switching can be replaced by a push or other that would operate an intermediate linkage (including spring).

Comme illustré à la figure 16, le robinet 1 peut comporter un dispositif 16 antivol ou un sceau de garanti frangible situe sur le mécanisme de commande (en combinaison ou alternativement au caractéristiques ci-dessus).As illustrated in figure 16 , the valve 1 may include an antitheft device 16 or a frangible guaranteed seal located on the control mechanism (in combination or alternatively with the above characteristics).

Par exemple le dispositif 16 antivol comprend un verrou à pêne 19 mobile actionné par une clé 18 ou autre (cf. figure s17 et 18). Par exemple, selon la position de la clé 18, le pêne 19 coopère ou non avec un logement de l'axe 12 de commutation pour verrouiller son déplacement.For example, the antitheft device 16 comprises a mobile bolt lock 19 actuated by a key 18 or the like (see FIGS. 17 and 18). For example, depending on the position of the key 18, the latch 19 cooperates or not with a housing of the axis 12 switching to lock its displacement.
