Le robinet 1 représenté aux figures comprend un corps 2 abritant classiquement un circuit 3 de fluide ayant une extrémité 4 amont destinée à être mise en relation avec une réserve de fluide sous pression (une bouteille 13 ou un ensemble de bouteilles par exemple) et une extrémité 5 aval destinée à être mise en relation avec un appareil utilisateur du gaz fourni par la réserve de fluide sous pression.The valve 1 shown in the figures comprises a body 2 conventionally housing a fluid circuit 3 having an upstream end 4 intended to be put in relation with a reserve of fluid under pressure (a bottle 13 or a set of bottles for example) and one end 5 Downstream intended to be connected to a user device of the gas supplied by the pressurized fluid reserve.

Comme illustré à la figure 1, le circuit 3 peut comprendre classiquement une vanne 6 de contrôle du débit dans le circuit 3. Cette vanne 6 peut être un clapet d'isolation pour l'ouverture ou la fermeture du circuit 3 et/ou un clapet permettant de régler un débit ou une pression ou tout autre type de clapet approprié.As illustrated in figure 1 , the circuit 3 may conventionally comprise a valve 6 for controlling the flow in the circuit 3. This valve 6 may be an isolation valve for opening or closing the circuit 3 and / or a valve for adjusting a flow rate or a pressure or any other type of suitable valve.

La vanne 6 est commandée par un levier 7 monté pivotant sur le corps 2 du robinet 1 (au niveau par exemple d'au moins une articulation 15).The valve 6 is controlled by a lever 7 pivotally mounted on the body 2 of the valve 1 (for example at least one articulation 15).

Le levier 7 est mobile entre une position de repos (figure 1) dans laquelle la vanne 6 est maintenu dans un premier état correspondant à une première valeur de débit dans le circuit 3 (par exemple un débit nul) et une seconde position active (levier relevé par exemple) dans laquelle le levier 7 déplace la vanne 6 dans un second état correspondant à une seconde valeur de débit dans le circuit 3 (par exemple circuit complètement ouvert pour un débit maximal).The lever 7 is movable between a rest position ( figure 1 ) in which the valve 6 is maintained in a first state corresponding to a first flow value in the circuit 3 (for example a zero flow) and a second active position (raised lever for example) in which the lever 7 moves the valve 6 in a second state corresponding to a second flow rate value in the circuit 3 (eg fully open circuit for maximum flow).

Comme schématisé à la figure 1, le robinet 1 peut être raccordé (fixé par exemple par vissage via des organes 12 d'accrochage) à une bouteille 13 de fluide sous pression.As schematized at figure 1 , the valve 1 can be connected (fixed for example by screwing via fastening members 12) to a bottle 13 of fluid under pressure.

L'organe 6 de contrôle de débit dans le circuit 3 représenté à la figure 1 comprend une vanne 6 mais tout autre organe 6 de contrôle de débit pourrait être envisagé.The flow control member 6 in the circuit 3 shown in FIG. figure 1 comprises a valve 6 but any other 6 flow control member could be considered.

Par exemple, en variante ou en combinaison, et comme illustré à la figure 2, le robinet 1 pourrait comprendre une pièce mobile telle qu'un pousse-clapet dont le mouvement est commandé par le levier 7. Ce pousse- clapet 6, par exemple mobile en translation, peut être prévu par exemple pour actionner (ouvrir notamment) un système de clapet(s) situé sur un autre robinet ou une bouteille sur lequel le robinet 1 vient se raccorder pour prélever ou transférer du fluide sous pression.For example, alternatively or in combination, and as illustrated in FIG. figure 2 , the valve 1 could comprise a moving part such as a valve push-piece whose movement is controlled by the lever 7. This valve push-button 6, for example mobile in translation, can be provided for example to actuate (open in particular) a valve system (s) located on another valve or a bottle on which the valve 1 is connected to collect or transfer fluid under pressure.

Par exemple, ce robinet 1 pourrait être raccordable (via les organes 12 d'accrochage) de façon amovible à un autre robinet distinct dit « robinet de base ». Ce robinet de base est par exemple solidaire d'au moins une bouteille 13 de fluide sous pression. Dans ce cas, le pousse-clapet 6 dont le déplacement est commandé par le levier 7 peut commander l'ouverture ou la fermeture d'un clapet d'isolation du robinet de base sur lequel est raccordé de façon amovible ledit robinet 1.For example, this valve 1 could be connectable (via the fastening members 12) removably to another separate valve called "base valve". This base valve is for example integral with at least one bottle 13 of fluid under pressure. In this case, the valve driver 6 whose movement is controlled by the lever 7 may control the opening or closing of an isolation valve of the base valve to which is connected removably said valve 1.

De même, le levier 7 pivotant peut être remplacé par tout autre organe d'actionnement approprié (bouton, volant, mobile en translation et/ou en rotation)...Similarly, the pivoting lever 7 can be replaced by any other appropriate actuator (button, steering wheel, mobile in translation and / or rotation) ...

Le robinet 1 comprend en outre au moins un organe 10 fonctionnel électronique. Le ou les organes 10 fonctionnels électroniques peuvent comprendre au moins l'un parmi : un dispositif réception et/ou d'émission de données sans fil comprenant une antenne, un capteur de pression, un capteur de température, une logique électronique de stockage et de traitement de données comprenant un microprocesseur, un écran digital, une source lumineuse...The valve 1 further comprises at least one electronic functional member. The electronic functional member (s) may comprise at least one of: a wireless reception and / or data transmission device comprising an antenna, a pressure sensor, a temperature sensor, an electronic storage and data processing comprising a microprocessor, a digital screen, a light source ...

Cet organe 10 fonctionnel électronique est disposé dans un boîtier 8 clos situé sur le corps 2.This electronic functional element is disposed in a closed casing 8 located on the body 2.

Ce boîtier 8 comprend en particulier une paroi périphérique en communication avec l'extérieur du robinet 1.This housing 8 comprises in particular a peripheral wall in communication with the outside of the tap 1.

Selon une particularité avantageuse, cette paroi 18 périphérique comprend au moins un orifice 9 d'évent refermé par un couvercle de préférence constitué d'une couche 11 de matériau plastique étanche collée sur ladite paroi 18 périphérique.According to an advantageous feature, this peripheral wall 18 comprises at least one vent orifice 9 closed by a lid preferably consisting of a layer 11 of waterproof plastic material bonded to said peripheral wall 18.

De cette façon, en cas d'accumulation de gaz sous pression dans le boîtier 8, si la pression dans le boîtier 8 devient trop importante, le gaz va déformer la couche 11 de matériau plastique collée en traversant l'orifice jusqu'à percer un passage pour s'évacuer vers l'extérieur du robinet 1. Ceci permet d'éviter des dégradations plus importantes du boîtier 18 et des composants électroniques qu'il renferme. Ceci permet de protéger les utilisateurs en évitant notamment une explosion plus dangereuse.In this way, in case of accumulation of pressurized gas in the housing 8, if the pressure in the housing 8 becomes too great, the gas will distort the layer 11 of plastic material bonded through the hole to drill a passage to escape to the outside of the valve 1. This avoids further damage to the housing 18 and the electronic components it contains. This protects users by avoiding a more dangerous explosion.

La couche 11 de matériau plastique est de préférence flexible. De cette façon, une déformation de celle-ci sous l'effet de la pression de gaz est susceptible de se produire. C'est-à-dire que la couche 11 de matériau collée peut gonfler avant de rompre.The layer 11 of plastics material is preferably flexible. In this way, a deformation thereof under the effect of the gas pressure is likely to occur. That is, the layer 11 of bonded material can swell before breaking.

Par exemple, cette couche 11 de matériau plastique peut comprendre au moins l'un parmi : du caoutchouc, un polymère.For example, this layer 11 of plastic material may comprise at least one of: rubber, a polymer.

En variante ce couvercle pourrait être rigide et/ou constituée d'un autre matériau que du plastique (par exemple une plaque métallique ou autre.Alternatively this cover could be rigid and / or made of a material other than plastic (eg a metal plate or the like.

Comme schématisé à la figure 4, la couche 11 de matériau plastique peut être localement amincie au niveau de l'orifice 9 d'évent, par exemple à l'aplomb et/ou à proximité de l'orifice 9.As schematized at figure 4 , the layer 11 of plastic material may be locally thinned at the level of the vent orifice 9, for example vertically and / or near the orifice 9.

En variante ou en combinaison, la couche 11 de matériau plastique peut être localement ou partiellement prédécoupée pour faciliter sa rupture de façon contrôlée.Alternatively or in combination, the layer 11 of plastic material may be locally or partially pre-cut to facilitate its breaking in a controlled manner.

La paroi 18 peut comporter un ou plusieurs orifices 9 d'évent (par exemple deux) ayant des dimensions comprises par exemple entre 0,1 et 0,7cm2.The wall 18 may comprise one or more vent orifices 9 (for example two) having dimensions of, for example, between 0.1 and 0.7 cm 2.

De préférence, le ou les orifices 9 sont situés sur la paroi 18 périphérique qui constitue une paroi supérieure du boîtier 8 et du robinet 1 lorsque le robinet 1 est en configuration d'utilisation.Preferably, the orifices 9 are located on the peripheral wall 18 which constitutes an upper wall of the housing 8 and the valve 1 when the valve 1 is in the configuration of use.

De plus, comme schématisé à la figure 2, le boitier 8 peut être monté de façon amovible sur le corps 2 du robinet 1.Moreover, as shown schematically in figure 2 , the housing 8 can be removably mounted on the body 2 of the valve 1.

Comme illustré à la figure 2, le boitier 8 contenant au moins un organe 10 électronique peut abriter au moins une partie du circuit 3 de fluide du robinet 1. Par exemple, le boîtier 8 peut comporter une portion de circuit comprenant au moins un organe de régulation (régulateur de débit et/ou de pression, vanne.... De plus, le au moins organe 10 électronique peut comporter un ou des capteurs électroniques (de pression et/ou de température par exemple).As illustrated in figure 2 , the housing 8 containing at least one electronic member 10 can house at least a portion of the fluid circuit 3 of the valve 1. For example, the housing 8 may comprise a circuit portion comprising at least one regulating member (flow regulator and In addition, the at least one electronic element may comprise one or more electronic sensors (pressure and / or temperature, for example).

Dans le cas où le boîtier 8 est amovible et comprend une portion du circuit 3 de fluide, cette portion peut comporter deux extrémités venant se raccorder de façon étanche (raccords) à deux extrémités de circuit en vis-à-vis sur le corps 2 du robinet 1. De cette façon, le circuit 3 de fluide ne fait qu'un passage dans le boîtier 8 (l'extrémité aval 5 du circuit étant située sur le corps 2 du robinet à l'extérieur du boîtier 8.In the case where the housing 8 is removable and comprises a portion of the fluid circuit 3, this portion may comprise two ends coming to connect sealingly (connections) to two circuit ends vis-à-vis the body 2 of the 1. In this way, the fluid circuit 3 makes only one passage in the housing 8 (the downstream end 5 of the circuit being located on the body 2 of the valve outside the housing 8.

De façon alternative, la portion de circuit 3 du boîtier 8 peut comprendre une entrée (unique) et une sortie 5 constituant l'extrémité aval du circuit 3.Alternatively, the circuit portion 3 of the housing 8 may comprise a (single) input and an output 5 constituting the downstream end of the circuit 3.
