Abstract

The device is for fitting and removing lining bladders used to protect diver's bottles from internal corrosion. Each bladder has a sealing joint and a collar forming the mouth. The collar (3) fits in a groove (6) formed in the periphery of the bottle tap (3) near the bottom end, and is held there by pressure in a passage (7) which is sealed off by a screw (8). The groove can be of semi-cylindrical or oval cross-section, and the passage can extend diagonally through the tap body, so as to allow air to escape from between the bottle wall (1) and the bladder (4).

Description

ta présente invention concerne un dispositif pour éviter la corrosion à l'intérieur des bouteilles de plongée, et pour simplifier leur reconditionnement. your present invention relates to a device for preventing corrosion inside diving tanks, and for simplifying their repackaging.

Il existe actuellement un brevet américain référencé sous le numéro 2 263932. Ce procédé est cependant d'une réalisation très complexe et présente quelques lacunes. En effet, il semble peu probable d'établir le vide entre la paroi de la bouteille et la vessie, car au moment de la mise en place, lorsqu'on enverra une pression dans la bouteille, la vessie prendra sa place et ob- struera l'échappement de l'air au niveau du goulot. D'autre part si le vide est réellement établi, comme il est indiqué, il sera impossible de retirer la vessie qui restera collée à la paroi. There currently exists an American patent referenced under the number 2 263932. This process is however of a very complex implementation and has some shortcomings. Indeed, it seems unlikely to establish a vacuum between the wall of the bottle and the bladder, because at the time of the installation, when one will send a pressure in the bottle, the bladder will take its place and will obstruct the air exhaust at the neck. On the other hand if the vacuum is really established, as indicated, it will be impossible to remove the bladder which will remain stuck to the wall.

A l'heure actuelle, en France, le conditionnement interne de ces bouteilles est fait d'un revêtemerlt du type epoxy ou rilsan,
Ces revêtements, quasi parfaits, présentent néanmoins un sérieux problème au moment du reconditionnement des bouteilles qui doit avoir lieu obligatoirement tous les cinq ans. En effet, l'intérieur de ces bouteilles doit etre mis à nu pour déceler d'éventuelles fissures ou micro tassures dans la structure du métal.At present, in France, the internal packaging of these bottles is made of a coating of the epoxy or rilsan type,
These almost perfect coatings nevertheless present a serious problem when the bottles are to be repackaged, which must take place every five years. Indeed, the interior of these bottles must be exposed to detect any cracks or micro-settling in the structure of the metal.

Une mise en oeuvre très importante et très onéreuse doit être déployée pour retirer ces revêtements.A very important and very expensive implementation must be deployed to remove these coatings.

le dispositif selon l'invention permet de remédier à cet inconvénient. Il est constitué d'une vessie en caoutchouc naturel qui se plaquera le long de la paroi grâce à une modification de la robinetterie. Cette vessie est imperméable à l'air. Au niveau du goulot, un renforcement est necessaire, car lors du rechargement en air, un échauffement se pwduit de l'ordre de 40 à 500. the device according to the invention overcomes this drawback. It consists of a natural rubber bladder which will be pressed along the wall thanks to a modification of the taps. This bladder is impermeable to air. At the level of the neck, reinforcement is necessary, because during the air reloading, a heating is produced in the order of 40 to 500.

La modification de la robinetterie consiste à execute g ne gorge située autour de l'extrémité inférieur du robinet qui sert à maintenir l'ouverture de la vessie et d'un condui gar lequel s' échappera l'air contenu entre la bouteille et la vessie. Ce conduit pariyejlediaa%%nr51iee centrale du robinet et aboutit dans la gorge. Avec ces deux éléments, la gorge et le conduit, le vide pourra être obtenu entre la vessie et la paroi de la bouteille et il sera maintenu à l'aide d'une vis d'étanchéité.The modification of the valve consists in executing a groove located around the lower end of the valve which is used to maintain the opening of the bladder and of a conduit which will escape the air contained between the bottle and the bladder. . This conduit pariyejlediaa %% nr51iee central tap and ends in the throat. With these two elements, the groove and the conduit, a vacuum can be obtained between the bladder and the wall of the bottle and it will be maintained using a sealing screw.

Il est donné à titre d'exemple non limitatif un mode de oeéali- sation se référant à la figure ci-annexée. La figure 1 représente, en coupe, un dispositif selon l'invention. A non-limiting example is given of an embodiment referring to the appended figure. Figure 1 shows, in section, a device according to the invention.

Le dispositif représenté sur la figure 1 comporte une bouteille (1) de plongée de type classique avec un goulot (2) à la par6 tie supérieltre, surmonté d'un robinet (9). la surface intérieure de la bouteille est reccuverte itune vessie (4). Cette ves- sie est en caoutchouc naturel ou autre ratière plastique c-io- priée. Cette vessie est tirée par trempage d'un modèle en ois ou en porcelaine d'une surépaisseur de 89 par rapport à la bouteille réelle. La vessie (4) se termine à sa partie supérieure ouverte par une collerette (5). La collerette est le surplus de caoutchouc qui se trouve à la terminaison de la vessie et qui forme un renflement arrondi.Cette collerette, d'un diamètre de 4 millimètres, viendra se loger dans la gorge (6) d'un diamètre de 6 millimètres et qui aura été préalablement graissée. la vese sie mise en place dans la bouteille, il faudra visser le robinet (3) et envoyer une pression, supérieure à la pression atmosphérique renfermée dans la bouteille, qui ainsi s'échappera par le conduit (7). le vide ainsi irait entre la paroi de la bouteille et la vessie, sera maintenu par une vis (8), dite d'étanchéité et marquée Haute Pression.La figure 2 représente le dispositif selon l'invention après sa mise en place. Pour retirer la vessie, il suffira d'introduire de l'air par la vis (8) sans oublier d'ouvrir le robinet (3). l1air ainsi injecté entre la paroi de la bouteille et la vessie, fera que la vessie se décollera. The device shown in FIG. 1 comprises a classic type diving bottle (1) with a neck (2) at the upper part, surmounted by a tap (9). the inner surface of the bottle is covered with a bladder (4). This bladder is made of natural rubber or other suitable plastic dobby. This bladder is drawn by soaking a model in bird or porcelain with an extra thickness of 89 compared to the real bottle. The bladder (4) ends at its upper open part with a collar (5). The collar is the surplus of rubber which is at the end of the bladder and which forms a rounded bulge. This collar, with a diameter of 4 millimeters, will be housed in the groove (6) with a diameter of 6 millimeters. and which has been previously greased. the vese sie installed in the bottle, it will be necessary to screw the tap (3) and send a pressure, higher than the atmospheric pressure enclosed in the bottle, which will thus escape through the conduit (7). the vacuum thus would go between the wall of the bottle and the bladder, will be maintained by a screw (8), called sealing and marked High Pressure. Figure 2 shows the device according to the invention after its installation. To remove the bladder, simply introduce air through the screw (8) without forgetting to open the valve (3). the air thus injected between the wall of the bottle and the bladder will cause the bladder to come off.

le dispositif selon l'invention est particulièrement adapté aux bouteilles de plongee, mais il n'est pas limité à ce domaine. En effet, on peut prévoir un dispositif analogue qui s'adapterait dans les bouteilles à air comprimé des camions, dans les réservoirs de compresseurs, dans les extincteurs, dans les cuves de chauffe-eau, dans les bouteilles tampons de réserve, et dans toutes les bouteilles en aluminium, pour éviter la porosité.  the device according to the invention is particularly suitable for diving tanks, but it is not limited to this area. Indeed, one can provide a similar device which would fit in the compressed air cylinders of trucks, in compressor tanks, in fire extinguishers, in water heater tanks, in reserve buffer bottles, and in all aluminum bottles, to avoid porosity.
