Description
La présente invention concerne un bloc robinet de distribution de gaz à dispositifindicateur électronique, tel un manomètre digital, et une bouteille de fluide sous pression équipée d'un tel bloc robinet.The present invention relates to a gas distribution valve block with electronic indicating device, such as a digital pressure gauge, and a bottle of pressurized fluid equipped with such a valve block.
Il est usuel d'équiper les récipients de fluide, notamment les bouteilles ou bonbonnes de gaz sous pression, d'un bloc robinet, encore appelé « robinet », pourvu d'un dispositif-indicateur électronique conçu pour fournir à l'utilisateur, une indication d'une ou plusieurs données physiques relatives au contenu du récipient de fluide, notamment la pression gazeuse.It is customary to equip the fluid containers, in particular the bottles or gas cylinders of pressurized gas, with a tap block, also called a “tap”, provided with an electronic indicator device designed to provide the user with a indication of one or more physical data relating to the content of the fluid container, in particular the gas pressure.
Ainsi, le dispositif-indicateur électronique peut être un manomètre électronique digital comprenant un capteur de pression et une logique électronique qui calcule et affiche des données de pression, de quantité de fluide et/ou d'autonomie, c'est-à-dire une estimation de durée d'utilisation.Thus, the electronic indicating device can be a digital electronic pressure gauge comprising a pressure sensor and an electronic logic which calculates and displays data of pressure, quantity of fluid and / or autonomy, that is to say a estimated duration of use.
Ainsi, EP-A-2029972 propose un dispositif indicateur d'une grandeur physique pour bouteille de gaz sous pression, comprenant un boîtier auquel est raccordé un capteur de mesure de la grandeur physique, tel un capteur de pression. Le boîtier comprend une carte électronique coopérant avec le capteur de mesure et reliée à un afficheur de la valeur représentative de la grandeur physique mesurée par le capteur.Thus, EP-A-2029972 proposes a device indicating a physical quantity for a pressurized gas bottle, comprising a housing to which a sensor for measuring the physical quantity, such as a pressure sensor, is connected. The housing includes an electronic card cooperating with the measurement sensor and connected to a display of the value representative of the physical quantity measured by the sensor.
Par ailleurs, WO-A-2005/93377 enseigne un module pour mesurer l'autonomie d'un gaz contenu dans un réservoir, telle une bouteille de gaz sous pression. Il comprend un capteur de pression relié à des moyens de calcul pour déterminer, à partir des données de pression mesurées, une information d'autonomie de fonctionnement du réservoir. Des moyens d'affichage permettent d'afficher l'information d'autonomie.Furthermore, WO-A-2005/93377 teaches a module for measuring the autonomy of a gas contained in a tank, such as a cylinder of pressurized gas. It comprises a pressure sensor connected to calculation means for determining, from the measured pressure data, information on the operating autonomy of the tank. Display means make it possible to display the autonomy information.
Ce type de dispositif-indicateur connu est souvent compact et peut donc aisément être positionné sur le bloc robinet pour ne pas être directement exposé aux chocs, en cas de chute de la bouteille. Sa protection peut être renforcée par un capotage ou « chapeau » de protection. Par ailleurs, la solidité du dispositif-indicateur peut être renforcée grâce à l'usage de résine ou analogue, appliquée pendant sa fabrication.This type of known indicator device is often compact and can therefore easily be positioned on the valve block so as not to be directly exposed to shocks, in the event of the bottle falling. Its protection can be reinforced by a protective hood or "hat". Furthermore, the solidity of the indicator device can be enhanced by the use of resin or the like, applied during its manufacture.
Or, un problème se pose lorsque le dispositif-indicateur électronique est plus volumineux et doit être positionné sur le haut du bloc robinet car il se retrouve alors plus exposé aux chocs et qu'en cas de choc, il existe un risque important de fuite de gaz et/ou d'éjection de pièces en contact avec le gaz à haute pression (HP) véhiculé par le passage interne du bloc robinet lui-même, notamment de l'élément de prise de pression situé au niveau du dispositif-indicateur, tel un manomètre digital.However, a problem arises when the electronic indicator device is larger and must be positioned on the top of the valve block because it is then more exposed to shocks and that in the event of an impact, there is a significant risk of leakage from gas and / or ejection of parts in contact with the high pressure gas (HP) conveyed by the internal passage of the valve block itself, in particular of the pressure tapping element located at the level of the indicating device, such a digital pressure gauge.
En d'autres termes, le problème est de garantir une intégrité de la partie HP du bloc robinet, même en cas de choc violent, de manière à éviter les fuites de gaz et/ou l'éjection de pièces en contact avec le gaz HP.In other words, the problem is to guarantee the integrity of the HP part of the valve block, even in the event of a violent impact, so as to avoid gas leaks and / or the ejection of parts in contact with HP gas. .

Figure 3) et une seconde extrémité aval, typiquement munie d'un raccord de sortie de gaz, destinée à être raccordée à un dispositif utilisateur de gaz soutiré.The valve block 1, which is for example made of brass and / or stainless steel, shelters an internal gas passage 4, also called first draw-off circuit, comprising a first upstream end communicating with the storage volume of a bottle 7 of pressurized fluid (see Figure 3) and a second downstream end, typically provided with a gas outlet connector, intended to be connected to a gas withdrawn user device.
Le passage interne de gaz 4 véhicule le gaz à haute pression (HP) provenant de la bouteille de gaz 7 sous pression sur laquelle est monté le RDI. Le passage interne de gaz 4 comprend un organe de régulation du débit et/ou de la pression du gaz soutiré entre les extrémités amont et aval.The internal gas passage 4 conveys the high pressure gas (HP) coming from the pressurized gas cylinder 7 on which the RDI is mounted. The internal gas passage 4 comprises a member for regulating the flow rate and / or the pressure of the gas withdrawn between the upstream and downstream ends.
Le RDI comprend par ailleurs un organe de commande manuelle de l'organe de régulation, monté mobile relativement au corps de robinet 1 et coopérant avec l'organe de régulation pour contrôler le débit et/ou la pression de fluide admis à circuler de l'extrémité amont vers l'extrémité aval selon la position de l'organe de commande par rapport au corps de robinet 1.The RDI also comprises a manual control member of the regulating member, mounted movable relative to the valve body 1 and cooperating with the regulating member to control the flow and / or the pressure of fluid admitted to circulate from the upstream end towards the downstream end according to the position of the control member relative to the valve body 1.
Le RDI comprend en outre un dispositif-indicateur électronique 3, c'est-à-dire un dispositif électronique d'indication de donnée(s) relative(s) au fluide contenu dans une bouteille sur laquelle est monté le robinet 1, par exemple un manomètre digital.The RDI further comprises an electronic indicator device 3, that is to say an electronic device for indicating data (s) relating to the fluid contained in a bottle on which the valve 1 is mounted, for example a digital pressure gauge.
Le dispositif-indicateur électronique 3 comprend une carte électronique permettant d'opérer une acquisition, un stockage et un traitement de données, notamment de la pression du gaz mesurée par un capteur de pression, et au moins un afficheur de données, à savoir un afficheur digital, relié à l'organe d'acquisition de stockage et de traitement de données, pour transmettre à ce dernier un signal représentatif du débit et/ou la pression de fluide imposé par l'organe de régulation.The electronic indicator device 3 comprises an electronic card making it possible to operate data acquisition, storage and processing, in particular of the gas pressure measured by a pressure sensor, and at least one data display, namely a display digital, connected to the storage and data acquisition acquisition device, to transmit to the latter a signal representative of the flow rate and / or the fluid pressure imposed by the regulating device.
Un élément de liaison 2, interposé entre le dispositif-indicateur électronique 3 et le corps de robinet 1, solidarise mécaniquement le dispositif-indicateur électronique 2 au corps de robinet 1.A connecting element 2, interposed between the electronic indicator device 3 and the valve body 1, mechanically secures the electronic indicator device 2 to the valve body 1.
L'élément de liaison 2 forme un raccord traversé par un canal interne 6 de gaz qui est en communication fluidique avec le passage interne 4 du corps 1 du RDI. Le canal interne 6 de gaz amène la pression gazeuse à un capteur de pression (non représenté) permettant de mesurer la pression du fluide HP véhiculé par le passage interne 4. Le capteur de pression délivre ensuite un signal de pression à la carte électronique du dispositif-indicateur électronique 3. Le capteur de pression peut être agencé sur ou intégré à l'élément de liaison 2.The connecting element 2 forms a connector crossed by an internal gas channel 6 which is in fluid communication with the internal passage 4 of the body 1 of the RDI. The internal gas channel 6 brings the gas pressure to a pressure sensor (not shown) making it possible to measure the pressure of the HP fluid conveyed by the internal passage 4. The pressure sensor then delivers a pressure signal to the electronic card of the device -electronic indicator 3. The pressure sensor can be arranged on or integrated into the connecting element 2.
Selon la présente invention, l'élément de liaison élastique 5 est agencé entre l'élément de liaison rigide 2 et le dispositif-indicateur électronique 3, et permet de solidariser mécaniquement le dispositif-indicateur électronique 3 à l'élément de liaison rigide 2According to the present invention, the elastic connecting element 5 is arranged between the rigid connecting element 2 and the electronic indicating device 3, and makes it possible to mechanically secure the electronic indicating device 3 to the rigid connecting element 2
Cet élément de liaison élastique 5 est conçu pour se déformer élastiquement, mais sans se rompre, en cas de choc sur le dispositif-indicateur électronique 3, en particulier d'un choc correspondant à une chute d'au moins 1 mètre de haut d'une bouteille de gaz 7 équipée d'un RDI selon l'invention, telle celle illustrée en Figure 3.This elastic connecting element 5 is designed to deform elastically, but without breaking, in the event of a shock to the electronic indicator device 3, in particular a shock corresponding to a fall of at least 1 meter high. a gas cylinder 7 fitted with an RDI according to the invention, such as that illustrated in FIG. 3.
Pour ce faire, l'élément de liaison élastique 5 est formé d'un matériau souple, flexible, déformable, en particulier d'un matériau élastomère.To do this, the elastic connecting element 5 is formed from a flexible, flexible, deformable material, in particular from an elastomeric material.
De préférence, l'élément de liaison souple 5 est surmoulé directement autour d'au moins une partie de l'élément de liaison rigide 2 et/ou du dispositif-indicateur électronique 3.Preferably, the flexible connecting element 5 is molded directly around at least part of the rigid connecting element 2 and / or of the electronic indicator device 3.
En fonctionnement normal, il s'opère un transfert d'informations, par exemple d'un signal de pression mesuré par le capteur de pression, vers l'électronique, c'est-à10 dire la carte électronique du dispositif-indicateur électronique 3.In normal operation, information is transferred, for example from a pressure signal measured by the pressure sensor, to the electronics, that is to say the electronic card of the electronic indicator device 3.
En cas de choc important, l'élément de liaison élastique 5 est conçu et adapté pour absorber le choc reçu par le dispositif-indicateur électronique, par exemple en cas de chute, et annuler ou limiter ainsi la transmission des efforts résultants à l'élément de liaison rigide et éviter que ce dernier ne se rompe. Dans ce cas, l'électronique ne cesse pas de fonctionner car elle reste reliée au capteur de pression. De plus, la partie HP du bloc 1 est préservée et reste sous pression, ce qui augmente la sécurité pour l'utilisateur.In the event of a significant impact, the elastic connecting element 5 is designed and adapted to absorb the impact received by the electronic indicating device, for example in the event of a fall, and thus cancel or limit the transmission of the resulting forces to the element. rigid connection and prevent it from breaking. In this case, the electronics do not stop working because it remains connected to the pressure sensor. In addition, the HP part of block 1 is preserved and remains under pressure, which increases safety for the user.
