Definitions

  • the invention relates to a compressed gas container for storing and transporting gases, preferably breathing gas.
  • Compressed gas containers made of steel are used for the storage and transport of high-tension gases and gas mixtures, which are seamlessly produced using the hot-forming process, with the bottle neck being molded using the spinning process and the valve seat being inserted in a cutting manner.
  • these pressurized gas containers are galvanized and coated on the outside in multiple layers. The for. Storage of gases under high pressure of 200 or 300 bar required wall thickness leads to high weights for steel containers. The use of such containers as a breathing air or oxygen bottle in rescue and rescue operations is of considerable disadvantage due to the high weight.
  • a pressure gas container is known from EP 0 410 884 B1, which has a thin-walled metal wall in the cylindrical region.
  • Lischen inner container which is surrounded on the outside with a jacket made of fiber composite material.
  • the inner container is made in two parts. It consists of a first calotte with an integrally formed cylinder part and a second calotte which is welded to the opening of the cylinder part.
  • the first part of the inner container is produced from a machined raw part in the cylindrical part by flow molding, the wall thickness decreasing from the spherical cap to the cylindrical part.
  • the second dome is also machined, with its wall thickness also decreasing towards the open end.
  • the inner container essentially has the function of ensuring the gas tightness of the compressed gas container, while a substantial part of the mechanical stability is applied by the outer jacket made of fiber composite material.
  • the weak points of the known fiber composite bottles are the connecting pieces, which are integrally formed on the container, as well as the manufacture of the inner container from two different container parts, which are produced by different complex processes. In addition, no significant weight saving is achieved. Finally, erosion resistance is also limited. Markings applied to the outside of the jacket, i.e. printed lettering or color schemes are not permanent.
  • the invention has for its object to provide a lightweight pressure gas container which is based on can be manufactured more cost-effectively and thus more economically.
  • the pressurized gas container according to the invention consists of a very thin-walled inner container made of metal, preferably of stainless steel, which consists of two almost identical, pot-like halves, which are produced in the pressure rolling process and are butt-welded together.
  • the inner container is only intended to ensure gas tightness, but is not designed to be able to absorb pressures.
  • This inner container is surrounded by a jacket made of wound fiber material, which gives the compressed gas container the mechanical strength to withstand the required loads for service gas pressures of up to 300 bar.
  • the connection part of the compressed gas container is designed as a separate part which is welded into the opening of a spherical cap of the inner container.
  • the connection piece which is provided with a thread, can be manufactured separately and no chips and other foreign matter get into the container during its assembly. The connection piece can be installed before the two container parts of the inner container are connected to one another.
  • the pot-like domes of the inner container have the same shape and can each have an outwardly directed shape at their pole, the shape of the one spherical cap forming the opening for the Connector is cut out.
  • the inner container consists of two equal parts which are butt-butted together in the middle by soldering or preferably by welding. This makes it possible to greatly simplify the manufacture of the inner container by producing only a single part which is assembled in pairs to form an inner container.
  • the jacket is preferably surrounded by a protective layer which consists of a polyurethane lacquer, polyurethane casting resin or a thermoplastic polyurethane and has a total layer thickness, which can consist of several individual layers, of 0.5 to 2 mm.
  • This coating is expediently transparent, so that imprints attached to the jacket can be read through it.
  • the protective layer not only protects the jacket itself, but also the marking.
  • the compressed gas container has an inner container 10 made of aluminum, rustproof, non-magnetic or hardenable stainless steel.
  • This inner container consists of a closed cap 11, an adjoining cylindrical container part 12 and a cap 13 which has an opening 14 in the pole area.
  • the inner container 10 is made of two identical halves 10a, 10b, which are connected to one another in the middle by a weld or solder seam 15, preferably a laser weld seam.
  • Each dome can be provided in its pole area with an outwardly directed round shape 16 which has a circumferential ring collar 17.
  • the wall above the ring collar 17 is cut off to form the opening 14 for receiving the connecting piece 20, so that an enlarged connection zone between the cap 13 and the connecting piece 20 required for soldering is produced.
  • the spherical cap 13 can, however, also be formed in an approximately semicircular shape without the formation 16. In this case, the connection piece 20 is welded in at the connection zone which is thus smaller.
  • the wall thickness of the inner container is greatest in the area of the formations 16 and it decreases steadily in the area of the calotte 11 or 13 as it approaches the edge of the calotte.
  • the decrease in wall thickness from the center of the cap to the outer cylindrical diameter is more than 50% and can preferably be up to 90% be. So while the wall thickness in the center of the cap is sufficient to withstand the internal pressure of the container, it is greatly reduced in the area of the cylindrical container part 12.
  • the two container parts 10a, 10b are produced by spinning rolls. According to this method, precise forming with a degressive wall thickness down to a tenth of a millimeter is possible in the cylindrical container region 12. With a 6 to 8-1 compressed gas container, the wall thickness in the cylindrical area should be approx. 0.3 to max. 0.8 mm.
  • an opening for receiving the connecting piece 18 is created in the container part 10b by cutting off the bottom, which opening can be surrounded by the annular collar 17. In this opening, the connector 18 is inserted from the inside, which is made as a separate part and consists of the same material as the calotte.
  • the connector 18 has a flange 19 from which a threaded connector 20 projects, which is provided with an internal thread 21.
  • the flange 19 is adapted to the inner contour of the cap 13 and is soldered or welded into the cap.
  • the connector 20 is provided on the outside with a recess which is delimited by an annular shoulder 22 facing the flange 19.
  • the annular collar 17 is pressed into this recess, the annular collar being supported on the one hand on the flange 19 and on the other hand on the shoulder 22 and absorbing axial loads on the connecting piece.
  • a further embodiment according to the invention is provided if the spherical cap is produced without molding 16. In this case, the connector 18 is welded with a flange 19 into the opening provided for this purpose.
  • the outer diameter of the flange 19 is matched to the opening in the calotte. The adjustment is only achieved by a small chamfer that protrudes beyond the flange.
  • the thin-walled inner container 10 cannot absorb high pressure loads with high expansion, it is surrounded by a jacket 25 made of wound fiber material. Suitable fibers are carbon, aramid or glass fibers, which are embedded in a laminate on epoxy or vinyl resins.
  • the jacket 25, which absorbs the high internal pressure, consists of wound layers with fibers running almost axially - preferably at + 10 ° to 20 ° - which are supported or covered and reinforced with radial layers - preferably in the cylindrical region 12.
  • the fiber layers can also be laid in several with fiber orientations of almost 0 ° to 90 °.
  • an adhesion promoter is applied to the inner container 10 before the jacket 25 is applied.
  • the wall thickness of the jacket 25 and the orientation of the fibers result from scientific calculations according to Camis and Puck, which are based on the working gas pressures and the required security.
  • the required marking is applied to the jacket 25, which then has a layer thickness of several millimeters.
  • the jacket 25 is covered with transparent coatings 26 which have a total layer thickness of 0.5 to 2 mm.
  • This coating 26 consists of polyurethane lacquer, but a casting resin or a thermo-elastic polyurethane can also be used.
  • the marking can also be applied after some, e.g. two or three coatings are carried out and then covered with further coatings if this results in better legibility.
  • the coating can also be carried out by extrusion coating with a transparent thermoplastic, preferably based on polyurethane.

Abstract

L'invention concerne un récipient à gaz comprimé comportant un réservoir intérieur en acier (10) dont l'épaisseur de la paroi dans la zone cylindrique (12) est si faible qu'elle ne supporte pas la pression intérieure. Le réservoir intérieur (10) est entouré d'une gaine (25) réalisée dans un matériau fibreux enroulé et présentant une résistance telle qu'elle peut supporter les hautes pressions requises. Le réservoir intérieur (10) est composé de deux parties (10a, 10b) fabriquées identiquement via un procédé d'emboutissage au tour et pouvant également comporter des renflements (16). Le renflement (16) est partiellement coupé sur une des parties du réservoir (10b) afin de créer une ouverture (14) permettant de fixer la pièce de raccord (18). Cela n'est toutefois pas obligatoire, car on peut également souder la pièce de raccord de façon à ne pas entraîner de diminution de la résistance au point de soudure. On peut produire le récipient à gaz comprimé à faible coût sous forme de récipient de poids léger.
