Definitions
- the invention relates to tanks for any fluid such as gas, at a pressure of the order of 10 to 500 bars, liquid, volatile or flammable, or hydraulic fluid.
- tanks made of composite materials composed of an internal envelope, ensuring fluid-tightness and made of molded synthetic materials, and of an external envelope, ensuring mechanical resistance and produced by resin reinforced by a winding. filamentary.
- the ends of such reservoirs are mechanically reinforced by metal bases interposed between the two envelopes and of which that disposed on the side of the normally open end of the reservoir is provided with a portion in the form of a nozzle, equipped with means for connection to a source of fluid supply or fluid outlet control, see for example EP-A-0 300 931.
- the practice shows, that in the event of a localized shock on one of the bases, as well as in the event of excessive external pressure on said base, as can happen with tanks for respiratory gases of plungers at great depth, the base can be pushed inside the tank causing the deterioration and even the rupture of the interior envelope, in the zone of this one bordering the periphery of the base.
- Such an accident allows the fluid to escape from the interior envelope and to migrate between the latter and the exterior envelope which, because of its structure, can allow the escape of the fluid under pressure outside.
- the object of the present invention is to remedy this by providing a protection device resistant to impact and to external pressures which is simple to implement and inexpensive.
- the device comprises, on each nozzle of the reservoir, on the one hand, a frustoconical metal cup, of the same conicity as the base of the nozzle and of external diameter at least equal to that of this base. , this cup being integral with a threaded bushing aimed at a thread produced on the external part of the end piece, on the other hand, a frustoconical washer made of elastic material interposed between the cup and the external face of the end of the reservoir and , in addition, a lock nut screwed onto the end piece.
- the cup absorbs all of the stresses and distributes them over its entire surface over the two tanks. This prevents any localization of the stresses and opposes any break in the connection between the internal and external envelopes of the reservoir, respectively, and therefore any deterioration of the latter.
- the washer made of elastic material absorbs the tightening torque during assembly and, in the event of an impact, constitutes an additional protective shock absorber for the tank.
- the protective cup also constitutes a support for marking by punching any indication concerning its structure, its content or its regulatory tests.
- this generally cylindrical tank comprises an internal envelope 3 made for example of polyamide, polypropylene or polyethylene, and an external envelope 4 made, for example, of epoxy resin reinforced with glass fibers and obtained by filament winding.
- This tank is equipped on the side of its closed end with a nozzle with bottom cup generally designated by 5, disposed between the two inner and outer envelopes and made of rigid material such as bronze, mechanical stainless steel, aluminum alloy or stainless steel.
- a part 6 made of the same material as the cup 5 and comprising a tubular part 7 forming a neck.
- the central bore 8 of this part is tapped at 9 to allow the connection of a tube, a regulator or a tap.
- This part 6 also includes a cup 10 which, like that 5, is provided with an external face 13 which, intended to come into contact with the external envelope 4, is frustoconical.
- Such a reservoir may also, as shown, on the right-hand side of the figure, comprise a coating 17 of fire and thermal protection, composed of two layers, namely an inner layer 18 constituted, for example, by a sheet of paper produced from ceramic fibers, and an outer layer 19 composed of a fire-resistant complex, glass fabric 20 - glass mat 21 assembled mechanically.
- a coating 17 of fire and thermal protection composed of two layers, namely an inner layer 18 constituted, for example, by a sheet of paper produced from ceramic fibers, and an outer layer 19 composed of a fire-resistant complex, glass fabric 20 - glass mat 21 assembled mechanically.
- each of the ends of the reservoir is reinforced by means disposed on each of its ends and comprising a metal cup 22, a washer 23 made of elastic material and a lock nut 24.
- the metal cup 22 is integral with a socket 22a internally threaded and screwed onto a thread 25 produced outside the axial post of the corresponding end piece.
- This cup is frustoconical and has the same taper as the bearing face 13 of the nozzle. Its outside diameter D is at least equal to the outside diameter of the corresponding nozzle.
- the washer 23 is frustoconical and is made of rubber or any other plastic and compressible material. This washer absorbs the tightening torque of the cup 22, but also absorbs a large part of the shocks or forces applied to the cup 22, thereby protecting the external envelope 4 of the tank.
- the cup 22 takes up all of the stress constraints, distributes them over the reservoir thanks to its large bearing surface and thus avoids any breakage of the connection of the external envelope 4 with the internal envelope 3 and of the internal envelope 3 with the corresponding base. In other words, this cup prevents any deterioration of the reservoir, either as a result of impact, or in the event of high external overpressure.
- the lock nut holds the cup 22 perfectly in place, avoiding its unscrewing.
- the right side of the figure shows that the protective cup can also be placed on the fire protection to ensure the same protection functions.
- the cup also constitutes a marking support, by punching or other, for all indications concerning the tank, its content or its certification tests.

Description
- L'invention est relative aux réservoirs pour fluide quelconque tel que gaz, à une pression de l'ordre de 10 à 500 bars, liquide, volatile ou inflammable, ou fluide hydraulique.
- Elle vise plus particulièrement les réservoirs en matériaux composites composés d'une enveloppe interne, assurant l'étanchéité aux fluides et réalisée en matériaux synthétiques moulés, et d'une enveloppe externe, assurant la résistance mécanique et réalisée par de la résine renforcée par un enroulement filamentaire. Les extrémités de tels réservoirs sont renforcées mécaniquement par des embases métalliques interposées entre les deux enveloppes et dont celle disposée du côté de l'extrémité normalement ouverte du réservoir est munie d'une partie en forme d'embout, équipée de moyens de raccordement à une source d'alimentation en fluide ou de contrôle de sortie du fluide, voir par example EP-A-0 300 931.
- L'usage montre, qu'en cas de choc localisé sur l'une des embases, de même qu'en cas de pression extérieure excessive sur ladite embase, comme cela peut se produire avec des réservoirs pour gaz respiratoires de plongeur à grande profondeur, l'embase peut être enfoncée à l'intérieur du réservoir en provoquant le détérioration et voire même la rupture de l'enveloppe intérieure, dans la zone de celle-ci bordant la périphérie de l'embase. Un tel accident permet au fluide de s'échapper de l'enveloppe intérieure et de migrer entre cette dernière et l'enveloppe extérieure qui, en raison de sa structure, peut permettre l'échappement du fluide sous pression à l'extérieur.
- La présente invention a pour but de remédier à cela en fournissant un dispositif de protection résistant au choc et aux pressions extérieures qui soit simple à mettre en oeuvre et peu onéreux.
- A cet effet, le dispositif selon l'invention comprend sur chaque embout du réservoir, d'une part, une coupelle métallique tronconique, de même conicité que l'embase de l'embout et de diamètre extérieur au moins égal à celui de cette embase, cette coupelle étant solidaire d'une douille filetée visée sur un filetage réalisé sur la partie extérieure de l'embout, d'autre part, une rondelle tronconique en matériau élastique interposée entre la coupelle et la face externe de l'extrémité du réservoir et, de plus, un contre écrou vissé sur l'embout.
- Grâce à cet agencement, en cas de chute du réservoir sur l'un de ces fonds, de même qu'en cas de choc intempestif ou de surpression externe, la coupelle absorbe la totalité des contraintes et les répartit, par toute sa surface, sur les deux enveloppes du réservoir. Cela empêche toute localisation des contraintes et s'oppose à toute rupture de la liaison entre les enveloppes respectivement interne et externe du réservoir, donc à toute détérioration de celui-ci. La rondelle en matière élastique absorbe au montage le couple de serrage et, en cas de choc, constitue un amortisseur de protection complémentaire du réservoir. Enfin, de par sa structure métallique, la coupelle de protection constitue aussi support de marquage par poinçonnage de toute indication concernant sa structure, son contenu ou ses épreuves réglementaires.
- D'autres caractéristiques et avantages ressortiront de la description qui suit en référence à l'unique figure du dessin schématique annexé représentant, en coupe transversale, une forme d'exécution d'un reservoir muni du dispositif, selon l'invention.
- De façon connue, ce réservoir de forme générale cylindrique comprend une enveloppe interne 3 réalisée par exemple en polyamide, en polypropylène ou polyéthylène, et une enveloppe externe 4 réalisée, par exemple, en résine époxy renforcée de fibres de verre et obtenue par enroulement filamentaire.
- Ce réservoir est équipé du côté de son extrémité fermée d'un embout avec coupelle de fond désigné de façon générale par 5, disposé entre les deux enveloppes interne et externe et réalisé en matériau rigide tel que bronze, acier inox mécanique, alliage d'aluminium ou acier inoxydable.
- A son extrémité ouverte, il est équipé d'une pièce 6 réalisée dans le même matériau que la coupelle 5 et comportant une partie tubulaire 7 formant goulot. L'alésage central 8 de cette pièce est taraudée en 9 pour permettre le raccordement d'une tubulure, d'un détendeur ou d'un robinet. Cette pièce 6 comporte également une coupelle 10 qui, de même que celle 5, est munie d'une face externe 13 qui, destinée à venir en contact avec l'enveloppe externe 4, est tronconique.
- Un tel réservoir peut également, comme représenté, sur la partie droite de la figure, comporter un revêtement 17 de protection anti-feu et thermique, composé de deux couches à savoir une couche intérieure 18 constituée, par exemple, par une feuille de papier réalisée à partir de fibres de céramique, et d'une couche extérieure 19 composée d'un complexe anti-feu, tissu de verre 20 - mat de verre 21 assemblés mécaniquement.
- Selon l'invention, chacune des extrémités du réservoir est renforcée par des moyens disposés sur chacun de ses embouts et comprenant une coupelle métallique 22, une rondelle 23 en matériau élastique et un contre écrou 24. La coupelle métallique 22 est solidaire d'une douille 22a filetée intérieurement et se vissant sur un filetage 25 réalisé à l'extérieur du tenon axial de l'embout correspondant. Cette coupelle est tronconique et a la même conicité que la face d'appui 13 de l'embout. Son diamètre extérieur D est au moins égal au diamètre extérieur de l'embout correspondant. La rondelle 23 est tronconique et est réalisée en caoutchouc ou en tout autre matériau plastique et compressible. Cette rondelle absorbe le couple de serrage de la coupelle 22, mais absorbe également une grande partie des chocs ou des efforts appliqués à la coupelle 22 en protégeant ainsi l'enveloppe externe 4 du réservoir.
- Grâce à cet agencement, en cas de chute du réservoir sur l'un des fonds, la coupelle 22 reprend l'ensemble des contraintes du choc, les répartit sur le réservoir grâce à sa grande surface d'appui et évite ainsi toute rupture de la liaison de l'enveloppe externe 4 avec l'enveloppe interne 3 et de l'enveloppe interne 3 avec l'embase correspondante. En d'autres termes, cette coupelle évite toute détérioration du réservoir, soit à la suite de choc, soit en cas de surpression externe élevée.
- Le contre-écrou maintient parfaitement en place la coupelle 22 en évitant son dévissage.
- La partie droite de la figure montre que la coupelle de protection peut aussi être mise en place sur la protection anti-feu pour assurer les mêmes fonctions de protection.
