Definitions
- the present invention relates to a pressurized fluid container and its method of manufacture.
- the invention relates more particularly to a pressurized fluid container, in particular a pressurized gas bottle, comprising a body forming a sealed storage volume for fluid, a first end of the body comprising an orifice, a second end of the body comprising a fixed foot. on the body, the body being made of a metallic material, a metal alloy or aluminum.
- Pressurized gas containers or cylinders are subject to standards such as international standard ISO 9809. These high-pressure containers (normally for pressures greater than 60 bar) are said to be “seamless” because their construction relies on shaping, usually by hot stamping, a sheet or billet or tube to obtain a so-called “monolithic” container. The use of welding to obtain the container is indeed not allowed on the entire surface for this type of construction.
- the bottom of the container may be concave or convex.
- the convex bottom geometry may allow the production of a relatively lighter container than a container of the same concave bottom storage volume.
- a container adapted to be worn, transported or moved by a user often requires to be arranged in a vertical position.
- a container convex bottom must be generally equipped with a foot, fixed on its bottom, to allow its vertical maintenance.
- the foot should also have a shape that avoids stagnant water or moisture that are aggravating corrosive factors.
- the assembly of a foot on a container can indeed lead to infiltration of water or moisture between the body of the container and the foot. This weakening factor can have serious consequences in terms of security.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the container according to the invention is essentially characterized in that the foot comprises a metallic material, a metal alloy or an aluminum alloy. having an electronegativity according to the Pauling scale greater than the electronegativity of the material composing the body.
- embodiments of the invention may include one or more of the following features:
- the body is made of steel having an electronegativity according to the Pauling scale between 1, 7 and 2, the foot comprising a material having an electronegativity according to the Pauling scale of between 1, 2 and 1, 6,
- the foot is composed of at least one of the following materials: an aluminum alloy, zinc, magnesium,
- the body is made of aluminum, an aluminum alloy or titanium and in that the foot is composed of magnesium,
- the foot is made of plastic coated with a metallic material, a metal alloy or aluminum having an electronegativity according to the scale of
- the foot (3) is fixed on the body by gluing
- the second end of the body is convex, the foot being glued on 5 to 25% and preferably 10 to 15% of the surface of the second convex end of the body,
- the foot has a flared upper end which converges towards the second end of the body
- the foot has a lower end folded towards the central part of the foot
- the second end of the body is at least partly housed in a volume delimited by the foot, the foot having a mass of between 20 and 50% of the mass of the portion of the second end of the body covered by the foot,
- the invention may also relate to any alternative device or method comprising any combination of the above or below features.
- the invention also relates to a method for manufacturing a pressurized fluid container, especially a pressurized gas bottle, from a body made of metallic material, metal alloy or aluminum, the body forming a sealed storage volume. for fluid and being provided with an orifice located at a first end, the method comprising a step of fixing, on a second end of the body, a foot comprising a metallic material, a metal alloy or a metal alloy, aluminum having an electronegativity according to the Pauling scale superior to the electronegativity of the material composing the body.
- the foot and the body are painted before or after the gluing of the foot on the body.
- FIG. 1 represents a sectional view, schematic and partial, illustrating an example of a gas container according to the invention
- FIGS. 2 to 5 represent perspective and schematic views respectively illustrating four possible embodiments of feet for a fluid container according to the invention
- FIG. 6 shows a perspective view and in vertical section of the foot of Figure 5.
- Figure 1 schematically shows a container of pressurized fluid, including a pressurized gas cylinder.
- This container comprises a body 1, for example cylindrical, forming a sealed storage volume for fluid.
- a first end of the body 1 of ogive shape comprises a port 2 for receiving for example a tap.
- a second end of the body 1 is convex and includes a foot fixed on the body 1.
- the body 1 is composed or made of a metallic material, a metal alloy or aluminum.
- the foot 3 comprises or consists of a metallic material, a metal alloy or an aluminum alloy having an electronegativity according to the Pauling scale greater than the electronegativity of the material composing the body 1.
- the foot 3 acts vis-à-vis the body 1 as anode which corrodes in priority, thus protecting the body 1 of the container of the possible risks of corrosion. Indeed, in case of presence of aggressive liquid such as water the most electronegative metal will corrode while the most electropositive metal will be protected according to the principle of galvanic protection.
- the foot 3 can be obtained by a plastic molding or injection technique.
- the cathodic protection of the body 1 of the container can be obtained by producing on the plastic foot 3 a treatment forming a coating on its plastic surface (for example a metallization with zinc or any other suitable material having an electronegativity greater than 1 Electronegativity of the body material 1).
- the foot 3 is glued to the body 1.
- This bonding can be achieved for example by using an epoxy type glue or a mono- or bicomponent adhesive, or a glue based on methylmethacrylate or based on polyurethane crosslinkable temperature or at room temperature.
- a first example of manufacture of the container may comprise the following steps:
- a step of producing the body by forming a sheet metal to produce a first end in the form of a warhead (first end), a bottom (second end) in determined thicknesses,
- a step of painting the body assembly 1 provided with its foot 3 for example by means of an electrostatic powder
- a step of drying the assembly to achieve the crosslinking of the glue drying of the paint
- the manufacturing method differs from the above only in that the body 1 and the foot 3 are painted before gluing and are glued after drying of the paint.
- the first example of manufacture allows a paint drying simultaneously with the crosslinking of the glue.
- the second example of manufacture may especially be used in the case where the crosslinking of the adhesive and the drying of the paint can not be obtained with the same final temperature cycle.
- the temperature at which the adhesive degrades is lower than the temperature at which the paint coating degrades, to allow maintenance of the foot without affecting the paint layer.
- the foot 3 has a shape provided so that the impact resistance and other mechanical stresses on the foot 3 are minimized. In this way, it minimizes the mechanical stresses on the glue, the risk of deformations of the foot (rigidity) and the risk of detachment of the foot.
- the foot 3 has a surface to be bonded at least equal to 5%, preferably greater than 15% to the surface of the bottom of the body 1 on which it sticks.
- the foot 3 may have the general shape of a ring whose upper end is upwardly flared to be glued in particular on the convex part of the end of the body 1.
- the lower end of the foot 3 forms an inward rim of the foot 3 and thus defines a flat base for stable holding of the container. This folded lower end of the foot 3 limits the risk of creating a cutting edge and abrasive dangerous for a user.
- FIG. 4 differs from that of FIG. 2 only in that the lower end of the foot 3 does not form an edge towards the inside of the foot 3. That is to say that the container rests on a lower circular border of the foot 3.
- the foot 3 comprises four plates connected perpendicularly to a circular base.
- the four decks can be glued to the end of the body 1 while the circular base, which is flat, allows the vertical stability of the container.
- the foot has the shape of a cylindrical tube whose upper end forms a folded flange downwardly and inwardly of the foot (see the cutaway view of the figure 6).
- the flange is intended to be glued on the end of the body 1. The container resting on the ground via the lower circular border.
- the resistance to abrasion of the foot 3 (ground friction for example) is minimized by the above geometries.
- the mass of the foot 3 is less than 50% of the equivalent mass of the portion of the bottom of the body 1 on which the foot is fixed.
- the foot 3 can be obtained by an industrial process of mechanical shaping, preferably by a stamping technique or mechanical spinning or foundry or welding of metal parts.
- the foot 3 can be magnetically fixed to the body 1, for example via one or more magnets crimped, glued or hooped on the foot 3.
- the invention makes it possible to produce a container that does not require the same measures for monitoring its corrosion as in the prior art. Indeed, a possible corrosion would be induced on the foot 3 and would not present a safety risk at the pressure vessel. Such corrosion can thus be confined to the foot 3 and can be tolerated.
