Description

Bouteille de gaz à capsule d'étanchéitéGas bottle with sealing cap
La présente invention se rapporte aux bouteilles de gaz et, plus précisément, aux bouteilles de gaz de pétrole liquéfié.The present invention relates to gas bottles and, more specifically, to liquefied petroleum gas bottles.
Une bouteille de gaz de pétrole liquéfié comporte un corps en un matériau résistant à la pression, notamment en métal ou en matériau composite. Dans le goulot du corps est montée une valve qui, lorsqu'elle est fermée, empêche que du gaz ne sorte du corps. L'action sur le robinet du détendeur fait se déplacer un piston, ce qui permet que du gaz sorte du corps. Un danger est que la valve fuie et que du gaz sorte intempestivement du corps et se répande dans la pièce où se trouve la bouteille de gaz.A bottle of liquefied petroleum gas comprises a body made of a pressure-resistant material, in particular metal or composite material. In the neck of the body is mounted a valve which, when closed, prevents gas from leaving the body. The action on the valve of the regulator makes move a piston, which allows that gas leaves the body. There is a danger that the valve may leak and that gas spills out of the body and spills into the room where the gas bottle is kept.
L'invention y porte remède par une capsule, en un matériau résistant moins à la pression que le matériau de la valve, qui coiffe la valve, une partie de la capsule délimitant avec la valve une chambre étanche au gaz, tandis qu'une autre partie de la capsule, qui ne participe pas à la délimitation de la chambre, est munie d'un organe de retenue conjugué d'un élément de la valve.The invention provides a remedy with a capsule, made of a material which is less resistant to pressure than the material of the valve, which covers the valve, a part of the capsule delimiting with the valve a gas-tight chamber, while another part of the capsule, which does not participate in the delimitation of the chamber, is provided with a retaining member conjugated with an element of the valve.
Certes la capsule, notamment en matière plastique, n'est pas apte à résister aux très fortes pressions qui régnent, par exemple dans une bouteille de gaz de pétrole liquéfié, mais elle est à même de contenir une fuite de gaz se produisant sur la valve, tant que la pression du gaz de fuite ne dépasse pas une certaine valeur, notamment 14 bar, inférieure à la pression du gaz régnant dans le corps et cependant elle peut être retirée facilement de la valve par l'utilisateur en déplaçant la partie qui ne délimite pas la chambre. Suivant un mode de réalisation qui assure une très bonne étanchéité, la valve comprend une cheminée métallique tubulaire et la capsule comprendAdmittedly the capsule, in particular in plastic material, is not able to resist the very strong pressures which reign, for example in a bottle of liquefied petroleum gas, but it is able to contain a gas leak occurring on the valve , as long as the pressure of the leaking gas does not exceed a certain value, in particular 14 bar, lower than the pressure of the gas prevailing in the body and however it can be easily removed from the valve by the user by moving the part which does not not demarcate the room. According to an embodiment which ensures a very good seal, the valve comprises a tubular metal chimney and the capsule comprises
FEUILLE DE REMPLACEMENT (REGEL 26) une paroi supérieure de laquelle est issue une partie tubulaire ouverte vers le bas, la face latérale extérieure de la partie tubulaire venant en contact avec interposition d'un joint d'étanchéité avec la face latérale intérieure de la cheminée. Lorsque, en raison d'une fuite de la valve, du gaz pénètre dans la chambre, la pression qu'il applique à la partie tubulaire permet, par l'intermédiaire du joint d'étanchéité, d'assurer une bonne étanchéité entre la face latérale intérieure de la cheminée et la face latérale extérieure de la partie tubulaire, en sorte que du gaz ne peut pas sortir de la chambre.SUBSTITUTE SHEET (REGEL 26) an upper wall from which comes a tubular part open downwards, the external lateral face of the tubular part coming into contact with interposition of a seal with the internal lateral face of the chimney. When, due to leakage of the valve, gas enters the chamber, the pressure which it applies to the tubular portion allows, through the seal, to ensure a good seal between the face inner side of the chimney and the outer side of the tubular part, so that gas cannot escape from the chamber.
De préférence, la cheminée métallique a une paroi extérieure munie d'un épaulement et la capsule comprend une jupe, une saillie sur la face intérieure de la jupe s'encliquetant sous l'épaulement. Cela contribue également à obtenir une bonne étanchéité de la chambre et empêche que la capsule ne se soulève du corps sous l'effet de la pression du gaz qui a pénétré dans la chambre. La saillie peut être par exemple une nervure. Cette nervure, qui peut être remplacée également par des saillies, de préférence réparties régulièrement sur le pourtour de la face intérieure de la jupe, vient derrière un rebord extérieur de la valve et assure ainsi que, même si du gaz fuit et tend à repousser la capsule, celle-ci est retenue. Le gaz qui fuit vient à l'intérieur de la partie tubulaire, puisque celle-ci est ouverte vers le bas et repousse ia surface latérale de la partie tubulaire vers la paroi adjacente de la valve, ce qui assure l'étanchéité.Preferably, the metal chimney has an external wall provided with a shoulder and the capsule comprises a skirt, a projection on the internal face of the skirt snapping under the shoulder. This also contributes to obtaining a good seal in the chamber and prevents the capsule from lifting from the body under the effect of the pressure of the gas which has entered the chamber. The projection may for example be a rib. This rib, which can also be replaced by protrusions, preferably distributed regularly around the periphery of the inner face of the skirt, comes behind an outer rim of the valve and thus ensures that, even if gas leaks and tends to repel the capsule, it is retained. The leaking gas comes inside the tubular part, since the latter is open downwards and pushes the lateral surface of the tubular part towards the adjacent wall of the valve, which ensures sealing.
De préférence, la jupe s'évase vers le bas, ce qui permet d'en encliqueter plus facilement la saillie.Preferably, the skirt flares down, which makes it easier to snap the projection.
Pour désencliqueter la saillie, il suffit de donner à la capsule un mouvement ayant une composante radiale, en sorte que la capsule bascule et se désencliquette. La force à appliquer pour le désencliquetage est petite et est à la portée de tout utilisateur habituel.To disengage the projection, it suffices to give the capsule a movement having a radial component, so that the capsule rocks and disengages. The force to be applied for the release is small and is within the reach of any usual user.
Suivant un mode de réalisation particulièrement préféré, la jupe est prolongée vers le bas, d'une part, sur une partie du bord inférieur de la jupe par une languette qui en est issue, et, d'autre part, sur une seconde partie du bord inférieur de la jupe, plus grande que la première partie, par une bande reliée au bord inférieur de la jupe par une première ligne de moindre résistance à la déchirure. Cette bande sert de bande d'inviolabilité. On ne peut désencliqueter la capsule qu'après avoir arraché cette bande.According to a particularly preferred embodiment, the skirt is extended downwards, on the one hand, on a part of the lower edge of the skirt by a tongue which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, larger than the first part, by a band connected to the lower edge of the skirt by a first line of least resistance to tearing. This band serves as a tamper-evident band. The capsule can only be disengaged after tearing off this strip.
FEUILLE DE REMPLACEMENT (REGEL 26) De préférence, la languette relie la jupe à un anneau. Même lorsque la bande est retirée, la coiffe reste maintenue sur la valve en une position où elle tend à revenir automatiquement en raison de l'élasticité de la languette, l'ensemble de la capsule étant de préférence en matière plastique souple. La capsule protège encore la valve des poussières, de la neige, de l'eau, de la chaleur, du soleil, du sable et autre dépôt de matière solide, mais aussi des fuites de la valve, même après que la bande d'inviolabilité a été retirée. De préférence, le bord inférieur de la bande est relié à l'anneau par une seconde ligne de moindre résistance à la déchirure. Cette seconde ligne de moindre résistance à la déchirure constitue une fixation supplémentaire de la bande et empêche que celle-ci ne se détache lorsque, par inadvertance ou par accident, la première ligne de moindre résistance à la déchirure est déchirée.SUBSTITUTE SHEET (REGEL 26) Preferably, the tongue connects the skirt to a ring. Even when the strip is removed, the cap remains held on the valve in a position where it tends to return automatically due to the elasticity of the tongue, the entire capsule preferably being made of flexible plastic. The capsule still protects the valve from dust, snow, water, heat, sun, sand and other solid deposits, but also from valve leaks, even after the tamper evident band has been withdrawn. Preferably, the lower edge of the strip is connected to the ring by a second line of least resistance to tearing. This second line of least resistance to tearing constitutes an additional fixing of the strip and prevents it from becoming detached when, inadvertently or by accident, the first line of least resistance to tearing is torn.
Au dessin annexé, donné uniquement à titre d'exemple: la figure 1 est une vue en perspective d'une capsule faisant partie d'une bouteille suivant l'invention, alors que l'on a commencé a en arracher la bande, la figure 2 en est une vue en coupe, et la figure 3 est une vue en coupe partielle d'une valve de bouteille suivant l'invention. Comme représenté aux figures, la capsule en matière plastique est formée d'une coiffe, qui comprend une paroi 1 supérieure circulaire prolongée vers le bas par une jupe 2 qui s'évase vers le bas. Une partie 3 tubulaire, de même axe XX' que la coiffe, est issue de la face inférieure de la paroi 3 supérieure et s'ouvre vers le bas. Une nervure 4 faisant tout le tour de la jupe 2 est prévue sur la face intérieure de celle-ci.In the accompanying drawing, given solely by way of example: FIG. 1 is a perspective view of a capsule forming part of a bottle according to the invention, while the strip has been torn off, FIG. 2 is a sectional view, and FIG. 3 is a partial sectional view of a bottle valve according to the invention. As shown in the figures, the plastic capsule is formed of a cap, which comprises a circular upper wall 1 extended downwards by a skirt 2 which widens downwards. A tubular part 3, of the same axis XX 'as the cap, comes from the underside of the upper wall 3 and opens downwards. A rib 4 running all around the skirt 2 is provided on the inner face of the latter.
La jupe 2 est prolongée vers le bas, d'une part, sur une partie du bord inférieur de la jupe par une languette 5 qui en est issue, et, d'autre part, sur une seconde partie du bord inférieur de la jupe, qui est plus grande que la première partie, par une bande 6 reliée au bord inférieur de la jupe 2 par une première ligne 7 de moindre résistance à la déchirure, constituée sous la forme d'une série de tenons équidistants.The skirt 2 is extended downwards, on the one hand, on a part of the lower edge of the skirt by a tongue 5 which results therefrom, and, on the other hand, on a second part of the lower edge of the skirt, which is larger than the first part, by a strip 6 connected to the lower edge of the skirt 2 by a first line 7 of lower resistance to tearing, constituted in the form of a series of equidistant pins.
La languette 5 relie la jupe 2 à un anneau 8 de plus grand diamètre que celui du bord inférieur de la jupe. Le bord inférieur de la bande 6 est relié à l'anneau 8 par une seconde ligne 9 de moindre résistance à la déchirure.The tongue 5 connects the skirt 2 to a ring 8 of larger diameter than that of the lower edge of the skirt. The lower edge of the strip 6 is connected to the ring 8 by a second line 9 of lower resistance to tearing.
FEUILLE DE REMPLACEMENT (REGEL 26) La figure 3 est une vue en coupe du haut d'une bouteille suivant l'invention.SUBSTITUTE SHEET (REGEL 26) Figure 3 is a sectional view from the top of a bottle according to the invention.
Cette bouteille comporte un corps 10 surmonté d'un goulot 11 dans lequel est vissée une valve, désignée dans son ensemble par 12. Cette valve comprend un corps de valve formant une cheminée 13 tubulaire supérieure dont la face extérieure comporte un épaulement 14 destiné à coopérer avec la saillie 4. Dans la face intérieure du corps 10 est maintenue par une bague 15 d'arrêt une bille 16 formant limiteur de débit. La bague porte un presse ressort 17 à l'intérieur duquel est enfilé un équipage 18 à piston 19 repoussé vers le haut par un ressort 20 dont l'une des extrémités s'appuie sur la face supérieure du presse ressort 17 et dont l'autre extrémité s'appuie sur un rebord 21 de l'équipage. Entre le piston 19 et le rebord 21 est prévu un joint d'étanchéité 22 qui vient en contact avec un siège 23 issu du corps 13 de valve. Lorsqu'un détendeur de gaz appuie sur le piston 19, l'équipage descend vers le bas à encontre de la force du ressort 20 et du gaz peut passer entre le siège 23 et le joint 22.This bottle comprises a body 10 surmounted by a neck 11 into which is screwed a valve, designated as a whole by 12. This valve comprises a valve body forming a chimney 13 upper tubular whose external face comprises a shoulder 14 intended to cooperate with the projection 4. In the inner face of the body 10 is held by a stop ring 15 a ball 16 forming a flow limiter. The ring carries a spring press 17 inside which is fitted a piston 18 equipment 19 pushed up by a spring 20, one end of which rests on the upper face of the spring press 17 and the other of which end rests on a rim 21 of the crew. Between the piston 19 and the flange 21 is provided a seal 22 which comes into contact with a seat 23 from the valve body 13. When a gas pressure regulator presses on the piston 19, the crew descends down against the force of the spring 20 and gas can pass between the seat 23 and the seal 22.
Au dessus du piston, est monté, dans un renfoncement de la face intérieure du corps 13, un joint 24 d'étanchéité, dont le diamètre intérieur correspond sensiblement au diamètre extérieur de la partie 3 tubulaire, en sorte que, lorsque celle-ci est enfilée dans la cheminée 13, elle s'y applique étroitement par l'intermédiaire de ce joint 24 d'étanchéité et délimite une chambre C étanche. Si la valve fuit, du gaz vient dans la chambre C, mais y est maintenu enfermé sans pouvoir en sortir et sans non plus que la force due à la pression appliquée à la capsule suffise à la soulever de la valve 12 et à l'en écarter en raison de la coopération de la saillie 4 et de l'épaulement 14.Above the piston, is mounted, in a recess of the inner face of the body 13, a seal 24, the inner diameter of which corresponds substantially to the outer diameter of the tubular part 3, so that, when the latter is threaded into the chimney 13, it is applied there tightly by means of this seal 24 and delimits a sealed chamber C. If the valve leaks, gas comes into the chamber C, but is kept locked in there without being able to come out of it and neither does the force due to the pressure applied to the capsule suffice to lift it from the valve 12 and in spread due to the cooperation of the projection 4 and the shoulder 14.
La capsule s'encliquette par la nervure 4 sur l'épaulement 14 de la valve 12 de la bouteille à gaz. En cette position, elle assure l'étanchéité, même si la valve 12 fuit. Pour dégager la valve 12, l'utilisateur détache la bande 6 d'inviolabilité, puis désencliquette la nervure 2. L'ouverture de la valve 12 peut être alors dégagée, en faisant basculer la coiffe par rapport à la languette 5 servant de charnière. Lorsqu'on ne veut plus prélever du gaz de la bouteille, on laisse la coiffe 1 et 2 revenir, en raison de l'élasticité de la languette 5, sur la valve 12, ce qui protège celle-ci de la neige, de l'eau, de la chaleur, du soleil, du gel et de dépôt de matière solide tel que du sable et, en la réencliquetant, assure encore l'étanchéité en cas de fuite de la valve 12.The capsule snaps into place through the rib 4 on the shoulder 14 of the valve 12 of the gas cylinder. In this position, it seals even if the valve 12 leaks. To release the valve 12, the user detaches the tamper-evident band 6, then disengages the rib 2. The opening of the valve 12 can then be released, by tilting the cover relative to the tongue 5 serving as a hinge. When you no longer want to take gas from the bottle, let the cap 1 and 2 return, due to the elasticity of the tongue 5, on the valve 12, which protects it from snow, l water, heat, sun, frost and deposit of solid matter such as sand and, by resetting it, still ensures sealing in the event of a valve 12 leak.
