Definitions

  • the invention relates to a pressure vessel unit with at least one composite pressure vessel and a method for producing such a pressure vessel unit.
  • the object of the invention is to disclose a pressure tank unit and a method for producing a pressure tank unit, wherein or in which the composite pressure tank is better protected against impact while reducing production costs.
  • the damping element made of plastic foam, in particular polyurethane foam, as a composite pressure vessel under zoned recess of at least one neck completely enveloping coat is formed.
  • composite pressure vessels for receiving compressed natural gas (CNG) have two ports. In this case, in some areas recesses are required on both neck pieces.
  • a jacket designed according to the invention not only protects the cap regions of the composite pressure vessel against impact, but also the cylindrical longitudinal section of the composite pressure vessel lying between the cap regions. This has the advantage that in principle no further protective measures are required in the area of the cylindrical length section in order to protect the composite pressure vessel against damage.
  • the jacket is in particular formed in one piece and surrounds the composite pressure vessel in a form-fitting manner. This allows the jacket can be easily removed from the composite pressure vessel in case of damage and then rebuilt by foaming.
  • an adhesive release layer is at least partially disposed between the shell and the composite pressure vessel, which is in particular a paint applied to the composite pressure vessel lacquer.
  • This paint which acts as an adhesive release layer for the plastic foam, is easy to process and simplifies subsequent repairs or replacement of the jacket considerably.
  • the production cost would be higher.
  • a further advantage of the adhesive release layer is that gases emerging through permeation from a plastic liner can be distributed between the jacket and the composite pressure vessel and can emerge in the neck in particular in the neck region or in openings provided for this purpose. As a result, local accumulations of gases, which could lead to bulging in the mantle, are avoided.
  • a significant advantage of the pressure vessel unit according to the invention is that the jacket can take any outer contour, while the composite pressure vessel can continue to maintain its generally cylindrical shape. This also has the advantage that the occurring in composite pressure vessels manufacturing tolerances of ⁇ 3% in length and diameter can be easily compensated. This means that the composite pressure vessel with the jacket completely enclosing it basically has the given desired outer contour, and in a much narrower tolerance range than is possible with an uncoated composite pressure vessel. This in turn results in an advantage in the attachment of the pressure vessel unit to a support frame. The state of the art is that tensioning straps compensate for the different diameters of the composite pressure vessels.
  • tensioning straps can also be used for fixation, however, other fastening possibilities are also conceivable, in particular particularly secure clip or snap connections, which hitherto could not be used due to the narrower tolerances.
  • the complete sheathing opens up new constructional scope.
  • the jacket contoured, z. B. polygonal for example, to prevent rolling of a horizontal pressure tank unit. But this can also be realized by evenly on the outer circumference and extending in the longitudinal direction of its cylindrical length ribs, which also prevent unhindered rolling at a corresponding distance.
  • the ribs do not need to be continuous. It is sufficient if the starting cross-section is at least partially out of round, be it by elongated ribs or individual local projections. In addition, can be formed on the mantle a footprint to turn off the pressure vessel unit can.
  • a supporting frame can be embedded directly in the jacket.
  • the support frame is also fixed captive on the composite pressure vessel due to the positive connection of the shell with the composite pressure vessel, so that open up different attachment options of the pressure vessel unit.
  • the support frame may be, for example, a metal or plastic frame comprising certain anchoring points on the outer cross section of the shell. In this way, the pressure tank unit according to the invention can be attached to different support devices.
  • the plastic foam is in particular an integral foam, i. that a cellular shell core is enclosed with a peripheral outer skin becoming denser to the edge zone. Ideally, the density distribution is equal to a parabola. Integral foams have the advantage that they can withstand greater mechanical stress on the outer shell of the shell, while the shell core has a damping effect due to its cellular structure. In particular, integral polyurethane foams are used.
  • the composite pressure vessel can be both a breathing air bottle and be provided for receiving compressed natural gas (CNG).
  • CNG compressed natural gas
  • the subject of claim 12 is a method for producing such a pressure vessel unit, in which a composite pressure vessel coated at least partially with an adhesive release layer for foaming inserted into a hollow mold and under zonal recess of a neck of the composite pressure vessel to form a shell completely with a plastic foam, especially polyurethane foam, is coated.
  • a support frame can be inserted into the hollow mold before the foaming of the composite pressure vessel.
  • Polyurethane foam is both light and sufficiently shock absorbent, so that this material is preferably suitable for use in combination with composite pressure vessels.
  • FIG. 1 shows in a longitudinal section a pressure vessel unit 1 designed as a respiratory protective bottle with a composite pressure vessel 2 and a jacket 3 surrounding the composite pressure vessel 2.
  • the structure of the composite pressure vessel is eg from the DE 197 51 411 C1 known. It consists of an inner liner 4, which is surrounded by a fiber winding 5.
  • the composite pressure vessel 2 has in its neck areas arranged neck pieces 6, 7, wherein the upper level in the image plane neck piece 6 is provided on the inside with a threaded portion 8 for fastening a valve.
  • the jacket 3 extends from pole cap to pole cap and the entire respirator bottle 1, with the exception of the connection region 9 of the neck piece 6 completely enveloped, so that an all-round shock protection is present.
  • a thin adhesive release layer is located between the shell 3 and the composite pressure vessel 2, a thin adhesive release layer.
  • the adhesive release layer is a paint applied to the composite pressure vessel 2, to which the polyurethane foam sheath 3 does not adhere.
  • At the lower pole cap of the respirator 1 of the jacket 3 is provided with a footprint 10 on which the respirator 1 can be turned off.
  • the wall thickness W of the shell 3 is constant. The wall thickness W is chosen only as an example and can be varied in coordination with the expected loads within wide limits.
  • FIGS. 2 to 4 show different embodiments of the outer cross-section of a jacket 3a, 3b, 3c.
  • the jacket 3a is hexagonal in its outer cross section.
  • two opposite parallel surfaces 12 are provided on an otherwise circular outer cross-section of a jacket 3b.
  • FIG. 4 shows an embodiment with six ribs 13 distributed over the outer circumference, on an otherwise circular outer cross-section of the jacket 3c.
  • FIGS 5 and 6 show a variant of a respirator 14, in which in the jacket 15, a support frame 16 is embedded.
  • two brackets 17 are provided by way of example in two different height levels, which emerge on a newly designed bearing surface 18.
  • the over the support surface 18 projecting portions of the bracket 17 are as Lugs 19 configured to serve as attachment means for the respirator 14.
  • FIGS. 7 and 8 show devices 20, 21 for producing a pressure vessel unit according to the invention.
  • the composite pressure vessel is placed in an at least two-part mold, which is filled after closing with polyurethane foam. This can be formed with high manufacturing accuracy, a composite pressure vessel completely enveloping coat, which is designed octagonal in this embodiment.
  • Circularly arranged heating elements 22 ensure the temperature level required for the production of the shell within the molding tool.
  • FIG. 7 shows how a coated composite pressure vessel 25 still lies in a lower mold half 23. Its outer contour corresponds exactly to the contour of the mold cavity of the mold halves.
  • the device 21 of Figure 8 differs from that of Figure 7 only in that the tool halves are not pivoted against each other, but in the direction of arrow P are opened and closed in a rectilinear motion.
