Description

La présente invention concerne les ensembles de stockage de gaz sousThe present invention relates to gas storage

pression, notamment des bouteilles ou recharges de gaz sous haute pression.  pressure, in particular bottles or refills of gas under high pressure.

Les ensembles de stockage de gaz sous pression posent des problèmes de connexion du réservoir sous pression à un circuit utilisateur. Pour y remédier, on prévoit habituellement d'équiper le réservoir d'un robinet détendeur, ce qui en obère toutefois considérablement les coûts, ainsi que la masse, et ne convient pas avec sécurité à des gaz fluides ou conditionnés sous haute pression, supérieure à 200 bars. De plus, les ensembles de stockage classiques posent des problèmes de manipulation et de pose, notamment lorsque les corps de réservoirs sont réalisés en matériaux composites avec des extrémités opposées arrondies en forme de dôme.  The pressurized gas storage assemblies pose problems of connection of the pressure tank to a user circuit. To remedy this, it is usually expected to equip the tank with a valve expansion valve, which however considerably obviates the costs, as well as the mass, and is not suitable for safety with fluid gases or conditioned under high pressure, greater than 200 bars. In addition, conventional storage assemblies pose problems of handling and laying, especially when the tank bodies are made of composite materials with opposite ends rounded domed.

La présente invention a pour objet de proposer un ensemble de stockage de gaz de sécurité et d'ergonomie accrues, de faible poids et convenant notamment pour des petites recharges de gaz sous très haute pression.  The object of the present invention is to provide an improved safety and ergonomics gas storage assembly, of low weight and particularly suitable for small refills of gas at very high pressure.

Pour ce faire, selon une caractéristique de l'invention, l'ensemble de stockage de gaz comprend un corps de réservoir oblong ayant, à une première extrémité, un clapet de distribution et comportant, au voisinage de la première extrémité, un premier collier monté sur le corps et comprenant des premiers moyens de connexion avec au moins une coiffe venant, en configuration montée sur le corps, du réservoir, recouvrir le clapet de distribution.  To do this, according to one characteristic of the invention, the gas storage assembly comprises an oblong tank body having, at a first end, a distribution valve and having, in the vicinity of the first end, a first mounted collar. on the body and comprising first connection means with at least one cap coming in configuration mounted on the body of the reservoir, cover the dispensing valve.

Selon d'autres caractéristiques plus particulières de l'invention: L'ensemble de stockage comprend, au voisinage de sa deuxième extrémité, un deuxième collier monté sur le corps et comportant des deuxièmes moyens de connexion avec au moins la coiffe.  According to other more particular features of the invention: The storage assembly comprises, in the vicinity of its second end, a second collar mounted on the body and having second connecting means with at least the cap.

- La coiffe comporte une jupe venant, en configuration de montage, coopérer en engagement avec le premier et/ou le deuxième collier, lesquels comportent typiquement des moyens de connexion rapides déverrouillables.  - The cap has a skirt coming, in the mounting configuration, cooperate in engagement with the first and / or second collar, which typically include releasable fast connection means.

- La première coiffe comporte un fond sensiblement plat.  - The first cap has a substantially flat bottom.

- La deuxième coiffe comporte une tête de soutirage de gaz coopérant, en configuration de montage sur la première extrémité, avec le clapet de distribution du corps de réservoir.  - The second cap has a cooperating gas withdrawal head, in mounting configuration on the first end, with the distribution valve of the tank body.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante de modes de réalisation donnés à titre illustratif mais nullement limitatif, faite en relation avec les dessins annexés, sur lesquels: - la figure 1 est une vue schématique partiellement en coupe longitudinale d'un mode de réalisation d'un ensemble de stockage de gaz selon l'invention, avant assemblage des coiffes; - la figure 2 est une vue de l'ensemble de stockage de la figure 1 en configuration de transport ou de stockage; - la figure 3 est une vue, partiellement en coupe longitudinale, à plus grande échelle, de la partie supérieure de la figure 1; et - la figure 4 est une vue analogue à la figure 1 montrant l'ensemble de stockage en configuration d'utilisation, en raccordement avec un circuit utilisateur.  Other characteristics and advantages of the invention will emerge from the following description of embodiments given by way of illustration but not by way of limitation, with reference to the accompanying drawings, in which: FIG. 1 is a diagrammatic view partly in longitudinal section; an embodiment of a gas storage assembly according to the invention, before assembling the caps; FIG. 2 is a view of the storage assembly of FIG. 1 in transport or storage configuration; - Figure 3 is a view, partly in longitudinal section, on a larger scale, of the upper part of Figure 1; and FIG. 4 is a view similar to FIG. 1 showing the storage assembly in use configuration, in connection with a user circuit.

Dans le mode de réalisation de la figure 1, on reconnaît un corps de réservoir 1 oblong présentant une partie principale cylindrique et deux extrémités en forme de dôme. Une première 2 de ces extrémités arrondies comporte une tête de remplissage et de distribution 3 comportant, comme on le voit mieux sur la figure 3, dans un bloc cylindrique rapporté 4 partiellement fermé par un bouclier annulaire 5 comportant une ouverture d'accès centrale, un clapet 6 sollicité par la pression du gaz dans le réservoir 1 coopérant avec un siège de clapet 7 et muni d'une tige 8 s'étendant vers le haut et optionnellement protégée par un opercule de protection 9 obturant normalement le passage central du bouclier 5.  In the embodiment of Figure 1, there is an elongate tank body 1 having a cylindrical main portion and two dome-shaped ends. A first 2 of these rounded ends comprises a filling and dispensing head 3 comprising, as best seen in FIG. 3, in a cylindrical insert block 4 partially closed by an annular shield 5 having a central access opening, a valve 6 biased by the pressure of the gas in the tank 1 cooperating with a valve seat 7 and provided with a rod 8 extending upwards and optionally protected by a protective cap 9 normally closing the central passage of the shield 5.

Selon un aspect de l'invention, sur la partie cylindrique du corps de réservoir 1 sont montés, au voisinage des extrémités opposées, un premier collier 10 et un deuxième collier 11. Chaque collier comporte une embase annulaire fixée au corps de réservoir 1 d'où s'étendent axialement, dans la direction vers l'extrémité adjacente du corps de réservoir 1, des pattes en matériau élastique angulairement réparties 12.  According to one aspect of the invention, on the cylindrical portion of the tank body 1 are mounted, in the vicinity of the opposite ends, a first collar 10 and a second collar 11. Each collar comprises an annular base fixed to the reservoir body 1 of wherein axially extending legs of angularly distributed resilient material 12 extend axially in the direction towards the adjacent end of the tank body 1.

Selon un autre aspect de l'invention, l'ensemble de stockage comporte une première 20 et une deuxième 21 coiffes amovibles comportant chacune une partie de jupe cylindrique 23 ayant un bord avant biseauté et destinée à venir s'engager à coulissement, en configuration de montage, sur l'embase d'un desdits colliers 10 ou 11 et pourvue d'ouvertures d'accrochage angulairement réparties 24, destinées à coopérer en engagement élastique avec des zones d'extrémité en saillie des pattes 12 formant des épaulements 25 de blocage et de retenue dans les ouvertures 24.  According to another aspect of the invention, the storage assembly comprises a first 20 and a second 21 removable caps each comprising a portion of cylindrical skirt 23 having a beveled front edge and intended to engage sliding, in the configuration of mounting, on the base of one of said collars 10 or 11 and provided with angularly distributed attachment openings 24, intended to cooperate in elastic engagement with projecting end regions of the tabs 12 forming shoulders 25 and in the openings 24.

Dans le mode de réalisation représenté la première coiffe 20, ou coiffe d'entreposage et d'attente, comporte un fond sensiblement plat transversal 26 permettant de poser l'ensemble verticalement sur une surface plane 27, comme représenté sur la figure 4. Avantageusement, le fond 26 comporte une coupelle annulaire 28 faisant saillie axialement vers l'intérieur, coaxialement à la jupe 20.  In the embodiment shown, the first cap 20, or storage and holding cap, has a substantially flat transverse bottom 26 for placing the assembly vertically on a flat surface 27, as shown in Figure 4. Advantageously, the bottom 26 has an annular cup 28 projecting axially inwards, coaxially with the skirt 20.

Dans la configuration de stockage ou de transport représentée sur la figure 2, la première coiffe 20 est montée par engagement élastique en position sur le premier collier 10 avec la cuvette 28 engagée sur le bouclier 5 pour abriter ce dernier. Dans cette configuration également le réservoir peut être posé, à l'envers, sur une surface plane.  In the storage or transport configuration shown in Figure 2, the first cap 20 is mounted by elastic engagement in position on the first collar 10 with the bowl 28 engaged on the shield 5 to house the latter. In this configuration also the tank can be placed, upside down, on a flat surface.

Dans la configuration de la figure 4, où la première coiffe 20, dégagée du premier collier 10, est montée sur le collier inférieur 11 et forme socle pour l'ensemble de stockage, la coupelle 28 s'étend au voisinage immédiat de l'extrémité du dôme inférieur du réservoir mais, normalement, sans contact avec ce dernier.  In the configuration of FIG. 4, where the first cap 20, freed from the first collar 10, is mounted on the lower collar 11 and forms a base for the storage assembly, the cup 28 extends in the immediate vicinity of the end the lower dome of the tank but, normally, without contact with the latter.

Dans le mode de réalisation représenté, la deuxième coiffe 21 ne comporte pas de fond plat mais une tête de raccordement de fluide 30 incluant notamment un passage central 31 destiné à recevoir, en configuration de montage (représentée sur la figure 4), la tête 4 du réservoir 1 et dans laquelle s'étend coaxialement une tige creuse 32 abritant une tige poussoir 33 solidaire d'un diaphragme 34 sollicité d'un côté par un ressort 35 et délimitant de l'autre côté une chambre communiquant avec l'extérieur par un raccord de sortie 36.  In the embodiment shown, the second cap 21 does not have a flat bottom but a fluid connection head 30 including in particular a central passage 31 intended to receive, in mounting configuration (shown in Figure 4), the head 4 of the reservoir 1 and in which coaxially extends a hollow rod 32 housing a push rod 33 integral with a diaphragm 34 biased on one side by a spring 35 and delimiting on the other side a chamber communicating with the outside by a outlet fitting 36.

Comme on le comprendra, en configuration de montage, la tige creuse 32 perce la capsule de protection 9, reçoit la tige de clapet 8, laquelle vient en appui axial contre l'extrémité de la tige 33 pour ouvrir le clapet 6, la pression de sortie étant régulée par l'équilibre entre la force du ressort de membrane 35 et la pression sur l'autre face de cette dernière.  As will be understood, in the mounting configuration, the hollow rod 32 pierces the protective cap 9, receives the valve stem 8, which bears axially against the end of the rod 33 to open the valve 6, the pressure of output being regulated by the balance between the force of the diaphragm spring 35 and the pressure on the other side thereof.

Avantageusement, le raccord de sortie 36 comporte un clapet anti retour et est relié à un manomètre monté ou intégré dans la tête 30.  Advantageously, the outlet fitting 36 comprises an anti-return valve and is connected to a manometer mounted or integrated in the head 30.

Selon les applications, les dimensions et les niveaux de pression, les coiffes 20 et 21 sont réalisées au moins partiellement en matériau plastique technique, par exemple en polyéthylène haute densité chargé de fibres, ainsi que les colliers 10 et 11, avantageusement réalisés d'une seule pièce et qui peuvent toutefois être réalisés en métal. Le corps de réservoir 1 peut aussi être réalisé en métal, typiquement en acier inoxydable mais, en particulier pour les petits réservoirs haute pression aisément transportables, par exemple pour l'alimentation de pile à combustible, pour les laboratoires ou pour des gaz à usage médical, le corps de réservoir 1 est avantageusement réalisé en matériau composite, typiquement avec un chemisage ( liner ) en alliage d'aluminium renforcé par bobinage de fibres, par exemple de carbone, inséré dans une matrice polymère, par exemple époxyde. En variante, le chemisage peut être également un polymère, typiquement du type PERD, les fibres pouvant alors être en polyaramide ou en verre. Dans ce cas, les colliers 10 et 11, au lieu d'être collés sur le corps du réservoir, sont avantageusement partiellement emprisonnés par des fibres du bobinage du corps de réservoir 1. Ce type d'ensemble de stockage convient tout particulièrement pour le stockage, sous une pression supérieure à 200 bars, typiquement supérieure à 300 bars, d'hydrogène servant à l'alimentation de pile à combustible PEM embarquée ou semi-stationnaire.  Depending on the applications, the dimensions and the pressure levels, the caps 20 and 21 are made at least partially of technical plastic material, for example high-density polyethylene loaded with fibers, as well as the collars 10 and 11, advantageously made of a only one piece and which can however be made of metal. The tank body 1 can also be made of metal, typically made of stainless steel, but in particular for small easily transportable high pressure tanks, for example for the fuel cell supply, for laboratories or for gases for medical use. , the tank body 1 is advantageously made of composite material, typically with a lining of aluminum alloy reinforced by winding fibers, for example carbon, inserted into a polymer matrix, for example epoxide. Alternatively, the liner may also be a polymer, typically of the PERD type, the fibers may then be polyaramid or glass. In this case, the collars 10 and 11, instead of being bonded to the body of the reservoir, are advantageously partially trapped by fibers of the winding of the tank body 1. This type of storage assembly is particularly suitable for storage at a pressure greater than 200 bars, typically greater than 300 bars, of hydrogen used for feeding PEM fuel cells on board or semi-stationary.

Bien que l'invention ait été décrite en relation avec des modes de réalisation particuliers, elle ne s'en trouve pas limitée mais est susceptible de modifications et de variantes qui apparaîtront à l'homme du métier dans le cadre des revendications ci-après.  Although the invention has been described in relation to particular embodiments, it is not limited but is subject to modifications and variations that will occur to those skilled in the art within the scope of the claims below.
