Description

DESCRIPTION
La présente invention concerne un dispositif inséré dans une bouteille de gaz
C02 qui a pour double fonction de permettre le remplissage de la bouteille et la détente du gaz.DESCRIPTION
The present invention relates to a device inserted in a gas cylinder
C02 which has the double function of allowing the filling of the bottle and the expansion of the gas.

Les bouteilles équipées de détendeur sont, aujourd'hui, conçues de deux façons: Dans un premier cas, la bouteille est équipée d'un robinet de fermeture qui permet le remplissage, et sur lequel s'adapte un détendeur indépendant comportant une tige d'entrée ou un système de connexion s'adaptant au robinet de fermeture. Bottles fitted with a regulator are today designed in two ways: In the first case, the bottle is fitted with a closing tap which allows filling, and on which an independent regulator with a stem adapts inlet or connection system adapting to the shut-off valve.

Dans un second cas, les bouteilles sont équipées d'un détendeur incorporé, comportant un système de remplissage de la bouteille. Dans les deux cas présentés ici, I'installation complète nécessite deux clapets un pour le remplissage de la bouteille, et l'autre pour le fonctionnement du détendeur. Ces deux conceptions représentent deux inconvénients : un coût supplémentaire dans le sens où le clapet est fabriqué deux fois, et deuxièmement cela entraîne deux causes de maintenance.In a second case, the bottles are equipped with a built-in regulator, comprising a bottle filling system. In the two cases presented here, the complete installation requires two valves, one for filling the bottle, and the other for operating the regulator. These two designs represent two drawbacks: an additional cost in the sense that the valve is manufactured twice, and secondly, there are two causes of maintenance.

Le dispositif selon l'invention permet de remédier à ces inconvénients. II comporte en effet selon une première caractéristique, la conception d'un détendeur en deux parties : une partie comprenant le corps, la membrane, le ressort de compression la vis de détente et le ou les manomètres, la deuxième partie consiste en une tige d'entrée, le clapet, le siège et toutes les pièces permettant le fonctionnement du clapet et son étanchéité. Les deux parties du détendeur sont distinctes et chacune des deux est homogène. Selon un deuxième caractéristique, la tige d'entrée est conçue de telle façon qu'elle s'adapte directement sur la bouteille de C02, pour que le clapet de détente serve à la fois de clapet de remplissage et de clapet de détendeur lorsque la partie corps du détendeur est remontée sur la partie clapet. The device according to the invention overcomes these drawbacks. According to a first characteristic, it in fact comprises the design of a regulator in two parts: a part comprising the body, the membrane, the compression spring, the expansion screw and the pressure gauge (s), the second part consists of a rod 'inlet, the valve, the seat and all the parts allowing the operation of the valve and its sealing. The two parts of the regulator are distinct and each of the two is homogeneous. According to a second characteristic, the inlet rod is designed in such a way that it fits directly onto the C02 bottle, so that the expansion valve serves both as a filling valve and as a pressure-reducing valve when the part body of the regulator is reassembled on the valve part.

Comme représenté sur la vue en coupe figure 5, (feuille 2/2), le système est composé de deux parties. La première partie est la partie qui se fixe dans la bouteille. As shown in the section view in Figure 5, (sheet 2/2), the system is made up of two parts. The first part is the part that fixes in the bottle.

Elle est composée de la pièce (4) qui est fixée dans la bouteille par un filetage. Elle intègre le clapet (6) qui sert à la fois de clapet de remplissage et de clapet de détente, le ressort de clapet et le bouchon (1) qui sert à maintenir le ressort (5) et le clapet (6).It consists of the part (4) which is fixed in the bottle by a thread. It incorporates the valve (6) which serves as both a filling valve and an expansion valve, the valve spring and the plug (1) which serves to hold the spring (5) and the valve (6).

La pièce (4) est aussi munie d'un diaphragme d'éclatement (2) qui est maintenu par un bouchon (3). La pièce (4) et le corps (28) forment à eux deux avec la membrane (13) et son joint (12), la chambre basse pression. The part (4) is also provided with a burst diaphragm (2) which is held by a plug (3). The part (4) and the body (28) together form the membrane (13) and its seal (12), the low pressure chamber.

La deuxième partie est le corps du détendeur composé par le corps (28) qui est muni d'une soupape de sécurité (26) composé du clapet (24) muni de son joint (25), d'un ressort (23) et d'un couvercle (22). Le gaz détendu sort du corps par l'embout de sortie (8) et de l'olive (10) fixé à l'embout de sortie (8) par un écrou (9). The second part is the body of the regulator composed by the body (28) which is provided with a safety valve (26) composed of the valve (24) provided with its seal (25), with a spring (23) and d 'a cover (22). The expanded gas leaves the body through the outlet nozzle (8) and the olive (10) fixed to the outlet nozzle (8) by a nut (9).

Le corps du détendeur (28) est muni d'un couvercle (21) qui enferme la vis de détente (17) imperdable qui est équipée d'une rondelle de blocage (18) pour éviter tout dépassement de pression, ainsi que d'un embout (19) et d'une barrette (20). The regulator body (28) is provided with a cover (21) which encloses the captive detent screw (17) which is equipped with a locking washer (18) to prevent any excess pressure, as well as a end piece (19) and a bar (20).

La vis de détente (17) appuie sur une rondelle (16) qui est en contact avec le ressort de détente (15) qui appuie à son tour sur un plateau de membrane (14) qui est en contact avec la membrane (13) qui appuie sur le poussoir de clapet (11), qui appuie à son tour sur le clapet (6) qui se situe dans l'autre partie vissée dans la bouteille. Les joints toriques (14) et (7), I'un placé sur la partie vissée dans la bouteille, et l'autre sur le corps (28) assurent une double sécurité afin d'éviter toute fuite de gaz détendu. The detent screw (17) presses on a washer (16) which is in contact with the detent spring (15) which in turn presses on a diaphragm plate (14) which is in contact with the diaphragm (13) which presses on the valve plunger (11), which in turn presses on the valve (6) which is located in the other part screwed into the bottle. The O-rings (14) and (7), one placed on the part screwed into the bottle, and the other on the body (28) provide double security in order to avoid any leakage of expanded gas.

Le système ainsi réuni forme un détendeur traditionnel qui fonctionne suivant le principe d'équilibre des forces entre deux ressorts. The system thus assembled forms a traditional regulator which operates according to the principle of balance of forces between two springs.

Selon des modes particuliers de réalisations: -.la forme du bouchon de bouteille est indifférente et peut subir diverses variations. According to particular embodiments: - the shape of the bottle cap is indifferent and can undergo various variations.

-.le système de connexion entre le corps du détendeur et la partie clapet fixée sur la bouteille peut être réalisée de diverses façons, notamment par un dispositif de raccord rapide.the connection system between the body of the regulator and the valve part fixed to the bottle can be produced in various ways, in particular by a quick coupling device.

- le dispositif décrit dans le présent brevet peut être adapté à d'autres gaz que le C02. - The device described in this patent can be adapted to other gases than C02.

Les dessins annexés illustrent l'invention:
La figure 1 représente le détendeur complet, (feuille 1/2).The accompanying drawings illustrate the invention:
Figure 1 shows the complete regulator, (sheet 1/2).

La figure 2 représente les deux parties du détendeur, (feuille 1/2).Figure 2 shows the two parts of the regulator, (sheet 1/2).

La figure 3 représente la bouteille munie du clapet dans la position de remplissage de la bouteille, (feuille 1/2)
La figure 4 représente le détendeur complet monté sur la bouteille, (feuille 1/2).Figure 3 shows the bottle with the valve in the bottle filling position, (sheet 1/2)
Figure 4 shows the complete regulator mounted on the cylinder, (sheet 1/2).

En référence à ces dessins, la partie corps du détendeur (1) se fixe sur la partie clapet (2). Le repère (3) représente le diaphragme d'éclatement. Sur la partie clapet du détendeur, la tige d'entrée (4) est destinée à être fixée sur la bouteille (7) par le côté fileté de la tige d'entrée (2). With reference to these drawings, the body part of the regulator (1) is fixed on the valve part (2). The mark (3) represents the burst diaphragm. On the valve part of the regulator, the inlet rod (4) is intended to be fixed to the cylinder (7) by the threaded side of the inlet rod (2).

Lorsque la tige d'entrée (2) est montée sur la bouteille (7), on peut remplir la bouteille de gaz par l'intermédiaire d'un connecteur (8). Une fois l'opération de remplissage terminée, le connecteur (8) est enlevé. Le corps du détendeur (1) est alors fixé sur le dispositif formé de la bouteille (7) et de la partie clapet (2). Ensuite, en manoeuvrant la vis de détente (9), I'utilisateur agit sur le clapet inclus dans la partie clapet du détendeur (2) et le gaz peut sortir par l'embout de sortie (10). When the inlet rod (2) is mounted on the bottle (7), the bottle can be filled with gas via a connector (8). Once the filling operation is completed, the connector (8) is removed. The regulator body (1) is then fixed on the device formed by the bottle (7) and the valve part (2). Then, by operating the detent screw (9), the user acts on the valve included in the valve part of the regulator (2) and the gas can exit through the outlet nozzle (10).

Pour remplir la bouteille lorsqu'elle est vide, le manipulateur désaccouple la partie corps de la partie clapet du détendeur, et raccorde le connecteur (8) sur le dispositif solidaire formé de la partie clapet (2) du détendeur et de la bouteille (7). To fill the bottle when it is empty, the manipulator uncouples the body part from the valve part of the regulator, and connects the connector (8) to the integral device formed by the valve part (2) of the regulator and the bottle (7 ).

Le dispositif selon l'invention est particulièrement destiné à équiper une bouteille de gaz comprimé ou liquéfié d'un clapet utilisable pour la détente et le remplissage.  The device according to the invention is particularly intended to equip a cylinder of compressed or liquefied gas with a valve usable for expansion and filling.
