Definitions

  • the invention relates to a pressure vessel and a method for producing a pressure vessel made of plastic for a pressurized, flowable or gaseous medium for pressures of up to 700 bar and above.
  • pressure vessels for pressurized, flowable or gaseous media for high pressures are described as composite pressure vessels consisting of a plastic liner with pole pieces or connection flanges with fiber-reinforced reinforcement arranged on the end faces
  • a pressure vessel for storing gaseous media which has a wall made of a fiber composite material and a liner made of plastic and a connection flange.
  • a section of an outer circumference of the connection flange is designed in a conical shape and interacts with a correspondingly designed support ring on the wall of the liner.
  • the cone is oriented in such a way that at the end of the connection flange pointing away from the actual pressure vessel, viewed in the longitudinal extension of the pressure vessel, the outer diameter of the flange is smaller than at its end pointing towards the pressure vessel.
  • the wall or the fiber composite material is equipped with a ring-shaped or collar-shaped support ring, which in turn is embodied in a correspondingly conical manner at least in sections on its inwardly facing surface.
  • the connection flange can thus be pushed outwards from the inside through the opening formed by the support ring. Due to the conical design of the connection flange and the inner surface of the support ring, a positionally and accurately fitting seat of the connection flange on the support ring is achieved.
  • the surfaces of the support ring and the connecting flange which are in direct contact with one another serve at the same time as a sealing surface in order to make the pressure vessel gas-tight even under high pressure.
  • the DE 10 2011 012 705 B4 discloses a pressure vessel for storing a fluid having an annular inner port having an inner surface and an outer surface, the inner surface defining a passage adapted to receive a supply device therein.
  • the inner port further includes a U-shape with a liner channel formed between the inner surface and the outer surface.

  • the liner or inner container can either have been produced by a rotary process, a thermal process or by extrusion blow molding.
  • the neck pieces are positively anchored to the liner.
  • the neck piece is provided with an annular groove into which the liner material engages in a form-fitting manner.
  • a clamping ring is pressed onto the end area of the liner.
  • a high-pressure tank which consists of a liner, a release agent layer arranged on a surface of the liner, and a reinforcement layer formed on the release agent layer (30).

  • the DE 11 2004 002 795 T5 / WO 2005 093313 A1 relates to a metal nozzle bead which is inserted into a plastic cladding of a composite container.
  • the container consists of two hoods produced by an injection molding process and a cylinder part produced by an extrusion process. The two hoods are connected by a thermal welding process with opposite ends of the cylinder part to form a container which is used as a core in a filament winding process.
  • carbon fiber impregnated with epoxy resin is wrapped around the cladding and cured to form a composite layer and thereby produce a desired high pressure composite container.

  • the metal nozzle bead also includes a seal device provided on a lower portion of the inner peripheral surface of the through hole.
  • the sealing device comprises a sealing ring mounting part holding a sealing ring, an external fastening thread which engages with the fastening part, and a fastening surface for applying a predetermined constant pressure to the fastening part, thus providing a desired sealing effect.
  • a sealing ring is placed over the sealing ring assembly part and is pressed together by the fastening part, with which the connection point between the metal nozzle bead and the plastic lining is sealed.
  • the sealing ring is compressed by the sealing ring mounting part, whereby it is deformed in a cranked sealing ring seat of the fastening part and with the junction between the Nozzle bead and the fairing comes into close contact. In this way, the sealing ring closes a passage for the escape of gas.

  • the pressure vessel comprises a plastic inner container with a neck piece connected to it.
  • the neck piece is arranged on the container neck in the region of the container opening and is provided with a support sleeve which at least partially encloses the plastic inner container and the neck piece.
  • the neck piece is provided with means for receiving a connection fitting.
  • An insert forms at least part of the container neck and a sealing seat for the fitting to be inserted into the neck piece.
