Definitions

  • the invention relates to a composite pressure vessel for storing gaseous media under pressure with a plastic liner according to the Preamble of the main claim.
  • a composite pressure vessel for storing known gaseous media under pressure.
  • This pressure vessel has a liner Plastic that is reinforced with a fiber composite material.
  • the neck area is each provided with an opening in which a closing and / or sealing neck piece is arranged.
  • One neck piece is designed so that it can accommodate a screw-in valve with a cylindrical thread.
  • For Anchoring the neck piece to the container has this in the container facing end area on a flat, frustoconical collar.
  • the collar is made of elements of the liner and / or the reinforcing winding surround.
  • a central axis extends into the neck from the inside as an axis of symmetry enclosing the recess in the case of the valve neck piece passes into the bore of the valve screwing area.
  • a disadvantage of this Construction is that the collar is very sharp and thus in the Corners high voltage peaks arise, which with appropriate thermal and / or mechanical stress can lead to leaks.
  • the generic EP 0 550 shows a somewhat different construction of the neck piece 951 A1.
  • the collar is carefully rounded and also the transitions in the Body of the neck piece. So that the liner is largely form-fitting with the neck piece is connectable, are usually in the collar area at least on the underside at least one annular recess is also provided on the upper side. This makes the neckpiece more expensive and complicates the assembly.
  • Figure 3 is on the inside of the neck piece in the Recess of the collar is provided with a latching tulip-like insert is clamped at the top by a screw-in clamping ring. Through this Construction improves the seal in the neck area, but it is very complex and requires a large number of individual parts, which are manufactured separately Need to become. The weak point of the construction remains the inadequate Connection of the liner to the tulip-like insert.
  • the object of the invention is to provide a generic composite pressure vessel Storage of gaseous media under pressure with a plastic liner specify that with a simple and inexpensive connection of the independent whether made of metal or plastic neck pieces on the container domes of the Plastic core container a long-term gastight seal even under combined changing mechanical and thermal load and the valve receiving tank dome without the prescribed valve torque Can absorb impairment.
  • the anchoring is between liners and neck piece improved.
  • the collar has at least two symmetrical the circumferentially arranged axially extending holes into which the liner engages like a cone.
  • the critical sealing area in the cylindrical part of the Neck piece is the arrangement of at least one lying on the inside annular groove provided, in which the liner engages in a form-fitting manner.
  • the valve provided neck piece preferably two in the axial Spaced annular grooves are provided.
  • the neck piece provided for receiving a valve by means of an intrinsically Known, screwed into the neck clamp ring, which is in the cylindrical portion of the neck piece extending end portion of the liner under Pressure pressed against the inside of the neck piece.
  • This has the advantage that not the critical only at high internal pressures, but also at low internal pressures End area of the liner is under tension. So that this effect is possible is effective, the clamping ring has a thread-free in a known manner frustoconical area with a corresponding one on the End area of the liner arranged on the inside of the liner cooperates.
  • a critical area of the previously known composite pressure vessels is the Transition area of the liner between the cylindrical jacket and the Neck area.
  • a significant improvement is achieved if, like proposed that this area be formed iso-tensoid. The corresponds to continuously curved course of approximation of one of many individual Sections of an existing polygonal train.
  • Advantage of the proposed training this transition area is that under load for the fiber reinforced Pressure vessel overall is an optimal state of tension in the transition from cylindrical container part to the metal end piece results in at the same time minimal use of the reinforcing fiber composite and maximum burst pressure.
  • the seal in the area of the clamping ring can be improved in this way be when you are in the contact area between the clamping ring and liner provides highly elastic sealant. This is used up in a way so that it is ensured that in particular the critical transition area between the frustoconical section and the threaded section of the clamping ring are sealed is.
  • the two neck areas of a composite pressure vessel 1 are shown in a half-sided longitudinal section. It consists of a plastic liner 2 produced by blow molding or rotation or thermoforming, which is reinforced by a fiber winding 3 wound from the outside.
  • the reinforcing wrap consists of a fiber reinforcement, for example carbon, aramid, glass, boron, Al 2 O 3 fibers or mixtures (hybrid game), which are contained in a matrix of thermosets, e.g. B. epoxy or phenolic resins etc. or in thermoplastics such. B. PA12, PA6, PP etc. are embedded.
  • the fiber composite material consisting of the above-mentioned fibers and polymers, is applied both in the axial and in the tangential direction of the container, i.e. the fiber reinforcement body (FRP) or the alignment of the fiber longitudinal axes have a small angle (0 °) in the case of axial wrapping in the cylindrical container part up to 60 °) with respect to the longitudinal axis of the container.
  • the pole caps of the plastic liner 2 are wound evenly.
  • the FRP is only deposited tangentially or in the circumferential direction of the cylindrical container part, consisting of both axial and tangential winding portions, but around the pole caps there is only one winding in the axial direction.
  • the wall thickness proportions of tangential wrapping and axial wrapping depend on the outer diameter of the plastic liner 2, on the strength of the FRP, on the winding angles etc.
  • the composite pressure vessel 1 has openings in the neck area, each with a Neck piece 4.5 are sealed.
  • the neck piece 5 opposite the valve has in a known manner on a frustoconical collar 6, which in The edge area is very rounded and its inclination corresponds to the contour of the liner 2 is adjusted.
  • the liner 2 in whole on the bottom 7 of the collar 6 to the system.
  • To reinforce the Anchoring has the collar 6 axially extending bores 8 into which the liner 2 engages like a cone. A total of four bores are preferably arranged are arranged symmetrically over the circumference.
  • the liner 2 is in this Area of the neck piece 5 closed, so that no sealing problem occurs here.
  • an annular groove 9 into which the liner material intervenes positively is also be two or more grooves.
  • the Recess 12 on the end face of the neck piece 5 serves to receive a Holding means, for example, a riding arbor tip. This is when winding the Container 1 required for inclusion in the rotating device of the winding system.
  • the collar 6 of the neck piece 4 faces axially extending holes 8, preferably four, symmetrically over the circumference distributed.
  • the additional anchoring also takes place via annular grooves 9, 10 in thread-free part 14 of the neck piece 4.
  • the seal is designed differently of the end region 13 of the liner 2.
  • a clamping ring 15 pressed onto the end region 13 of the liner 2.
  • the clamping ring 15 has one Threaded portion 16 and a thread-free truncated cone Section 17.
  • the latter section 17 corresponds to the bevel of the end area 13 of the liner 2.
  • the clamping ring 15 can be rotated, it has an internal hexagon 18.
  • a selected prestress is applied to the end region 13 of the liner 2.
  • the arrangement described requires a cylindrical configuration of the Threaded portion 19 of the neck piece 4. This in turn means that also Valve 20 must also have a cylindrical thread.
  • an annular groove 21 into which a seal 22 can be fixed.
  • the critical one because of the tension Transition area 30 from the cylindrical jacket 11 to the neck area of the liner 2 is trained iso-tensoid.
  • the continuously curved profile shown here is an approximation of a polygonal train consisting of many sections. The Such a curve is determined using many small iterative steps.
  • FIG 3 shows a representation similar to Figure 1 another Embodiment of the valve connection, the same for the same parts Reference numerals have been chosen.
  • the thread-free part 23 of the neck piece 25 extends inside the container. This has the advantage that the container length accordingly overall is getting shorter. It is necessary with this arrangement that the liner 2 around the thread-free part 23 is guided around.
  • the other elements are the same as in Figure 1, so that there is no need to repeat the explanation.
  • FIGs 4a, b is on an enlarged scale and in a plan view of the End region 13 of the liner 2 (Fig. 1) cooperating clamping ring 15 shown.
  • the hexagon socket 18 is used to insert a hexagon key, so that the Clamping ring 15 can be rotated accordingly. So that the rotation is sensitive can take place, the threaded portion 16 is provided with a fine thread.
