Definitions
- the present invention relates to an assembly comprising a valve and a protective cap and a bottle comprising such an assembly.
- the invention more particularly relates to an assembly comprising a valve for controlling a fluid under pressure and a protective cap mounted around said valve, as defined by claim 1.
- the invention relates in particular to a system for delivering gas from a bottle, in particular a bottle of small volume (10 liters of geometric volume containing compressed gas at, for example, 150 to 300 bar).
- the invention applies in particular to bottles equipped with a valve easily connectable to regulators of different types and ensuring (the valve) an emergency stop function (or at least a quick stop) of the withdrawal of the gas and giving a visible indication on the "open” (On) or “off” (Off) state of the faucet.
- valve is described for example in documents FR-A1-2828922 or FR-A1-2793297 (The invention can be applied to any other type of valve and is not limited to the examples described in the documents above).
- the invention therefore also relates to a protective cap, preferably of composite material, having an opening for handling a valve actuating lever, however the cap is sufficiently covering to protect the valve in case of a fall for example.
- a valve having at least one lever likely to overflow out of the protection volume conferred by the cap has better visibility and better maneuverability for an operator.
- the document EP 747 796 describes such an assembly in which the cap is mounted on the bottle in a fixed indexed angular position and determined with respect to the valve.
- a rotating cap relative to the faucet and the bottle, to provide the user with some freedom to facilitate installation, maintenance and connection to the faucet.
- a rotating cap In use position a rotating cap is mounted "crazy" that is to say free to rotate relative to the entire valve and bottle. That is to say that the user can choose (turn) the angular position of the cap without having to disassemble it (the locking in translation is however preserved).
- a rotating cap is particularly advantageous when installing the valve on the bottle because it does not require angular indexing between the valve and the cap. Being able to orient the cap (rotating) relative to the fixed valve also increases the convenience of use, for example to connect a regulator or a hose. Finally, to check the condition of the valve and / or to maintain it, the fact of being able to turn the cap makes it possible to examine the valve and its connection to the bottle from all angles and makes it possible to intervene easily.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the assembly according to the invention is essentially characterized in that the cap is rotatable relative to the valve body around the vertical axis and in that the portion of the cap defining the first opening has contact edges likely to come into contact with the lever when on the one hand it intercepts the plane of the first opening and on the other hand the cap is rotated relative to the valve, the contact edges being oriented at predetermined angles to induce a force on the lever urging it to its first position.
- the invention may also relate to a bottle of pressurized fluid, in particular nitrogen-containing gas, the assembly being mounted at its orifice, the valve being rotatably mounted on the bottle, for example by screwing, and in that the cap is rotatably mounted relative to the vertical axis of the bottle and the valve via a rotating fastening system such as a circlip cooperating with a groove.
- a bottle of pressurized fluid in particular nitrogen-containing gas
- the invention may also relate to any alternative device or method comprising any combination of the above or below features.
- the device illustrated in figure 1 comprises a pressurized gas bottle 3 in the orifice of which is mounted (for example by screwing) a valve 1 provided with a pivoting lever 5 (for actuating a valve or isolating valve for example).
- the lever 5 is for example articulated in the upper part of the valve 1 and can be moved manually between a position near the valve body 1 on a side face of the valve (valve closed) and a position separated by a non-zero angle (open valve ).
- the lever 5 may include other intermediate positions (open or closed valve).
- valve 1 On another of its side faces the valve 1 may comprise a pressure gauge 14 (or outlet can receive such a gauge) and a take 4 draw (intended to be connected to a hose for example).
- a pressure gauge 14 or outlet can receive such a gauge
- a take 4 draw intended to be connected to a hose for example.
- a cap 2 is mounted around the valve 1 in a rotating manner. That is to say that the cap 2 is linked in translation to the bottle 3 but can rotate relative to the bottle about the vertical axis A of the bottle 3 and the valve 1. Preferably, the cap 2 can rotate freely 360 ° around the tap 1.
- Hat 2 may comprise a structure forming two substantially vertical "arches” (or lobes) formed on two lateral flanks of hat 2.
- a first arch defines a first lateral opening 12 intended to be disposed opposite the lever 5.
- the second arch defines a second 22 and a third 32 lateral openings.
- the lever 5 When the lever 5 is located vis-à-vis the first opening 12, the pivoting of the lever 5 outwards is possible between two extreme positions. In its spaced apart position the lever 5 intersects the imaginary plane of the first opening 12 and may project beyond the volume of the cap 2 (cf. figures 1 and 3 ).
- these contact edges 102 are oriented at predetermined angles to induce in this case a force on the lever 5 urging it towards its folded position (towards the valve body 1).
- the contact edges 102 may have an inclined orientation B with respect to the vertical axis A and / or at least a portion of the contact edges 102 are bent or inclined towards the interior of the first opening and / or the contact edges 102 have a portion inclined at an angle of between 14 and 30 degrees and preferably between 17 and 25 degrees with respect to the vertical axis A.
- the inclined portion may be included in a curve such as a segment of a circle.
- the tangent to the curve makes with the vertical axis, an angle at least equal to the minimum of the limits described above.
- the second opening 22 and the third opening 32 are arranged one 22 above the other 32 and separated by the horizontal post 52 which can form a gripping member of the bottle 3.
- the dimensions of the second 22 and third 32 openings are preferably selected so as to prevent lever 5 from pivoting thereon.
- the dimensions of the second 22 and third 32 openings are also provided to make it impossible (or poorly) to mount a regulator on the filling plug 4 when the latter is located vis-à-vis the second arch.
- the cap 2 further comprises a fourth opening 42 located on a side face between two adjacent ends of the two arches.
- the fourth opening 42 (preferably open at the top) is provided to form a sufficient access to the face of the valve 1 provided with the gauge 14 and the take 4 draw (for mounting a pressure regulator) and optionally d a filling plug (not shown).
- the cap 2 is shaped to allow the use of the valve of the bottle 3 only in a finite sector of angular positions of the cap 2 with respect to the tap 1. In the rest of the angular positions, the cap 2 can be dimensioned either to prevent the complete pivoting of the lever 5, or to prevent the connection of a regulator (or other organ) to the socket racking 4.
- the cap 2 is shaped to prevent the correct use of the valve 1 in these positions (ie the lever 5 can not be properly lifted or a regulator can not be connected).
- the cap 2 is made of plastic and has a relative elasticity during an impact.
- the cap 2 also has a light structure to protect the valve 1 without using a large amount of material (weight and cost).
- This very aerated architecture also ensures good visibility of the interior of the protected volume.
- the invention applies in particular to multi-purpose portable gas cylinders (itinerant professional applications in particular) for which the valve built-in trigger is not necessarily provided because of, for example, too great a pressure adjustment dynamic or in flow or because of requirements that vary from one use to another (request for control of flow rate or pressure).
- the invention can be applied to nitrogen cylinders for air conditioning system installers for whom, depending on whether to inert pipes or fill a circuit or leak test, and according to the types of systems, the required pressure can vary between 1 bar and 50 bar.
- the invention can also be applied to cylinders used on a high-pressure circuit (central, backup power supply, safety devices) without regulator directly connected.
- the invention can however also be applied to valves with integrated expansion valve.
- the invention may where appropriate relate to all or part of the technical characteristics of the cap independently of the valve.
- the technical characteristics of the cap 2 can be realized by giving the cap 2 other shapes / arrangements, it being understood that, in all cases (including the example shown), the characteristics of the invention are independent of the aesthetic appearance of the hat.

Description
La présente invention concerne un ensemble comprenant un robinet et un chapeau de protection ainsi qu'une bouteille comprenant un tel ensemble.The present invention relates to an assembly comprising a valve and a protective cap and a bottle comprising such an assembly.
L'invention concerne plus particulièrement un ensemble comprenant un robinet de contrôle d'un fluide sous pression et un chapeau de protection monté autour dudit robinet, tel que défini par la revendication 1.The invention more particularly relates to an assembly comprising a valve for controlling a fluid under pressure and a protective cap mounted around said valve, as defined by claim 1.
L'invention concerne notamment un système de délivrance de gaz à partir d'une bouteille, en particulier une bouteille de faible volume (10 litres de volume géométrique contenant du gaz comprimé à, par exemple, 150 à 300 bars).The invention relates in particular to a system for delivering gas from a bottle, in particular a bottle of small volume (10 liters of geometric volume containing compressed gas at, for example, 150 to 300 bar).
L'invention s'applique notamment aux bouteilles munies d'un robinet facilement connectable à des détendeurs de différents types et assurant (le robinet) une fonction d'arrêt d'urgence (ou au moins d'arrêt rapide) du soutirage du gaz et donnant une indication visible sur l'état « ouvert » (On) ou « fermé » (Off) du robinet.The invention applies in particular to bottles equipped with a valve easily connectable to regulators of different types and ensuring (the valve) an emergency stop function (or at least a quick stop) of the withdrawal of the gas and giving a visible indication on the "open" (On) or "off" (Off) state of the faucet.
Un tel robinet est décrit par exemple dans les documents
L'invention concerne donc également un chapeau de protection, de préférence en matière composite, ayant une ouverture permettant la manipulation d'un levier d'actionnement du robinet, le chapeau étant cependant suffisamment couvrant pour protéger le robinet en cas de chute par exemple.The invention therefore also relates to a protective cap, preferably of composite material, having an opening for handling a valve actuating lever, however the cap is sufficiently covering to protect the valve in case of a fall for example.
Un robinet ayant au moins un levier susceptible éventuellement de déborder hors du volume de protection conféré par le chapeau présente une meilleure visibilité et une meilleure manoeuvrabilité pour un opérateur. Cependant, dans ce cas il y a un risque un risque de choc et de casse en cas notamment de chute de l'ensemble. Le document
Dans certaines applications, il est préférable de prévoir un chapeau tournant relativement au robinet et à la bouteille, pour offrir à l'utilisateur une certaine liberté pour faciliter l'installation, la maintenance et la connexion au robinet. En position d'utilisation un chapeau tournant est monté « fou » c'est-à-dire libre en rotation relativement à l'ensemble robinet et bouteille. C'est-à-dire que l'utilisateur peut choisir (tourner) la position angulaire du chapeau sans avoir à le démonter (le blocage en translation est cependant conservé).In some applications, it is preferable to provide a rotating cap relative to the faucet and the bottle, to provide the user with some freedom to facilitate installation, maintenance and connection to the faucet. In use position a rotating cap is mounted "crazy" that is to say free to rotate relative to the entire valve and bottle. That is to say that the user can choose (turn) the angular position of the cap without having to disassemble it (the locking in translation is however preserved).
Un chapeau tournant est notamment avantageux lors de l'installation du robinet sur la bouteille car il ne nécessite pas d'indexation angulaire entre le robinet et le chapeau. Le fait de pouvoir orienter le chapeau (tournant) par rapport au robinet fixe augmente également la commodité d'utilisation, par exemple pour connecter un détendeur ou un flexible. Enfin, pour vérifier l'état du robinet et/ou procéder à sa maintenance, le fait de pouvoir faire tourner le chapeau permet d'examiner le robinet et son raccordement à la bouteille sous tous les angles et permet d'intervenir facilement.A rotating cap is particularly advantageous when installing the valve on the bottle because it does not require angular indexing between the valve and the cap. Being able to orient the cap (rotating) relative to the fixed valve also increases the convenience of use, for example to connect a regulator or a hose. Finally, to check the condition of the valve and / or to maintain it, the fact of being able to turn the cap makes it possible to examine the valve and its connection to the bottle from all angles and makes it possible to intervene easily.
Avec un chapeau tournant il y a risque de collision entre le chapeau et le levier lors, par exemple, du transport ou lors d'une chute de la bouteille.With a rotating cap there is a risk of collision between the cap and the lever during, for example, transport or during a fall of the bottle.
Une solution possible consiste à limiter la rotation du chapeau par des butées et/ou à renforcer le levier et/ou à faire en sorte qu'en cas de rupture du levier la partie restante de levier est de taille suffisante pour que le robinet puisse tout de même être actionné.One possible solution is to limit the rotation of the cap by stops and / or to strengthen the lever and / or to ensure that in case of breakage of the lever the remaining portion of the lever is of sufficient size that the valve can all likewise be operated.
Ces solutions sont cependant complexes ou coûteuses ou limitent l'ergonomie et l'usage des bouteilles correspondantes.These solutions are however complex or expensive or limit the ergonomics and the use of the corresponding bottles.

Le dispositif illustré à la
Le levier 5 est par exemple articulé en partie supérieure du robinet 1 et peut être déplacé manuellement entre une position près du corps du robinet 1 sur une face latérale du robinet (vanne fermée) et une position écartée d'un angle non nul (vanne ouverte). Bien sûr, le levier 5 peut comporter d'autres positions intermédiaires (vanne ouverte ou fermée).The
Sur une autre de ses faces latérales le robinet 1 peut comporter une jauge 14 de pression (ou sortie pouvant recevoir une telle jauge) et une prise 4 de soutirage (destinée à être reliée à un flexible par exemple).On another of its side faces the valve 1 may comprise a pressure gauge 14 (or outlet can receive such a gauge) and a take 4 draw (intended to be connected to a hose for example).
Un chapeau 2 est monté autour du robinet 1 de façon tournante. C'est-à-dire que le chapeau 2 est lié en translation à la bouteille 3 mais peut tourner par rapport à la bouteille autour de l'axe A vertical de la bouteille 3 et du robinet 1. De préférence, le chapeau 2 peut tourner librement sur 360° autour du robinet 1.A
Le chapeau 2 peut comprendre une structure formant deux « arches » (ou lobes) sensiblement verticales formées sur deux flancs latéraux du chapeau 2.
Une première arche définit une première ouverture 12 latérale destinée à être disposée en vis-à-vis du levier 5. La seconde arche définit une seconde 22 et une troisième 32 ouvertures latérales.A first arch defines a first
Lorsque le levier 5 est situé en vis-à-vis de première ouverture 12, le pivotement du levier 5 vers l'extérieur est possible entre deux positions extrêmes. Dans sa position écartée le levier 5 coupe le plan fictif de la première ouverture 12 et fait éventuellement saillie au-delà du volume du chapeau 2 (cf.
Dans cette position relevée du levier 5, si le chapeau 2 est pivoté (manipulation ou chute par exemple), la portion du chapeau 2 délimitant la première ouverture 102 peut entrer en contact avec le levier 5 au niveau de bordures 102 dites de contact.In this raised position of the
Selon l'invention, ces bordures de contact 102 sont orientées selon des angles prédéterminés pour induire dans ce cas un effort sur le levier 5 le sollicitant vers sa position rabattue (vers le corps du robinet 1).According to the invention, these
De cette façon, la rotation du chapeau 2 en cours d'utilisation (levier 5 relevé) entraîne (ou au moins favorise) mécaniquement et automatiquement la fermeture du levier 5. Cette fermeture résulte de la forme particulière prédéterminée des montants de la première ouverture 12 au travers de la quelle le levier 5 est normalement manoeuvré (levé pour ouvrir un clapet, baissé pour fermer un clapet).In this way, the rotation of the
Par exemple, au moins une partie des bordures 102 de contact peut présenter une orientation B inclinée par rapport à l'axe A vertical et/ou au moins une partie des bordures 102 de contact sont cintrées ou inclinées vers l'intérieur de la première ouverture et/ou les bordures 102 de contact présentent une portion inclinée d'un angle compris entre 14 et 30 degrés et de préférence entre 17 et 25 degrés par rapport à l'axe A vertical. La portion inclinée peut être incluse dans une courbe comme par exemple un segment de cercle. De préférence dans la zone de contact entre le levier et la dite courbe, la tangente à la courbe fait avec l'axe vertical, un angle au moins égal au minimum des limites décrites ci avant.For example, at least a portion of the contact edges 102 may have an inclined orientation B with respect to the vertical axis A and / or at least a portion of the contact edges 102 are bent or inclined towards the interior of the first opening and / or the contact edges 102 have a portion inclined at an angle of between 14 and 30 degrees and preferably between 17 and 25 degrees with respect to the vertical axis A. The inclined portion may be included in a curve such as a segment of a circle. Preferably in the contact zone between the lever and said curve, the tangent to the curve makes with the vertical axis, an angle at least equal to the minimum of the limits described above.
La seconde 22 ouverture et la troisième 32 ouverture sont disposées l'une 22 au dessus de l'autre 32 et séparées par le montant 52 horizontal pouvant former un organe de préhension de la bouteille 3.The
Les dimensions des seconde 22 et troisième 32 ouvertures (ainsi que le montant 52 horizontal) sont choisies de préférence de façon à empêcher que levier 5 puisse pivoter de ce côté. Les dimensions des secondes 22 et troisième 32 ouvertures sont également prévues pour rendre impossible (ou rendre mal aisé) le montage d'un détendeur sur la prise 4 de remplissage lorsque cette dernière est située en vis-à-vis de la seconde arche.The dimensions of the second 22 and third 32 openings (as well as the horizontal post 52) are preferably selected so as to prevent
Le chapeau 2 comprend en outre une quatrième ouverture 42 située sur une face latérale entre deux extrémités adjacentes des deux arches. La quatrième ouverture 42 (de préférence ouverte en partie supérieure) est prévue pour former un accès suffisant à la face du robinet 1 pourvue de la jauge 14 et de la prise 4 de soutirage (en vue du montage d'un détendeur) et éventuellement d'une prise de remplissage (non représentée).The
De préférence, pour garantir que le levier 5 se trouve effectivement dans la ou les zones zone du chapeau 2 qui le protège, le chapeau 2 est conformé pour ne permettre l'utilisation du robinet de la bouteille 3 que dans un secteur fini de positions angulaires du chapeau 2 par rapport au robinet 1. Dans le reste des positions angulaires, le chapeau 2 peut être dimensionné soit pour empêcher le pivotement complet du levier 5, soit pour empêcher la connexion d'un détendeur (ou un autre organe) à la prise de soutirage 4.Preferably, to ensure that the
Donc si une partie des positions relatives du chapeau 2 par rapport au robinet 1 n'assurent pas la protection du levier 5, le chapeau 2 est conformé pour empêcher l'utilisation correcte du robinet 1 dans ces positions (soit le levier 5 ne peut pas être levé correctement soit un détendeur ne peut pas être connecté).So if a part of the relative positions of the
De préférence le chapeau 2 est réalisé en plastique et a une relative élasticité lors d'un choc.Preferably the
Le chapeau 2 présente par ailleurs une structure légère permettant de protéger le robinet 1 sans utiliser une grande quantité de matière (masse et coût avantageux).The
Cette architecture très aérée assure de plus une bonne visibilité de l'intérieur du volume protégé.This very aerated architecture also ensures good visibility of the interior of the protected volume.
L'invention s'applique notamment aux bouteilles de gaz portables multi usages (applications professionnelles itinérantes notamment) pour lesquelles la détente intégrée dans le robinet n'est pas forcément prévue du fait, par exemple d'une trop grande dynamique de réglage en pression ou en débit ou du fait d'exigences variables d'une utilisation à l'autre (demande de contrôle soit du débit soit de la pression).The invention applies in particular to multi-purpose portable gas cylinders (itinerant professional applications in particular) for which the valve built-in trigger is not necessarily provided because of, for example, too great a pressure adjustment dynamic or in flow or because of requirements that vary from one use to another (request for control of flow rate or pressure).
L'invention peut s'appliquer aux bouteilles d'azote pour les installateurs de systèmes de climatisation pour lesquels selon qu'il s'agisse d'inerter des canalisations ou de remplir un circuit ou de vérification d'étanchéité, et selon les types de systèmes, la pression requise peut varier entre 1 bar et 50 bar.The invention can be applied to nitrogen cylinders for air conditioning system installers for whom, depending on whether to inert pipes or fill a circuit or leak test, and according to the types of systems, the required pressure can vary between 1 bar and 50 bar.
L'invention peut s'appliquer aussi aux bouteilles utilisées sur un circuit haute pression (centrale, sauvegarde d'alimentation, dispositifs de sécurité) sans détendeur directement raccordé.The invention can also be applied to cylinders used on a high-pressure circuit (central, backup power supply, safety devices) without regulator directly connected.
L'invention peut cependant s'appliquer également aux robinets avec détendeur intégré.The invention can however also be applied to valves with integrated expansion valve.
L'invention peut le cas échéant concerner tout ou partie des caractéristiques techniques du chapeau indépendamment du robinet.The invention may where appropriate relate to all or part of the technical characteristics of the cap independently of the valve.
Par ailleurs, les caractéristiques techniques du chapeau 2 peuvent être réalisées en conférant au chapeau 2 d'autres formes/agencements, étant entendu que, dans tous les cas (y compris l'exemple représenté), les caractéristiques de l'invention sont indépendantes de l'aspect esthétique du chapeau.Furthermore, the technical characteristics of the
