Definitions

  • the present invention relates to construction of an inlet/outlet system (boss) for composite pressure receptacles.
  • Composite pressure receptacles are generally used for storing, transporting and distributing fluids and gases under high or low pressures, such as LPG, CNG, industrial gases or air.
  • a composite pressure receptacle consists of a composite container containing a composite outer shell bearing all pressure loads, an inner liner ensuring sealing of the container, usually made of polymer or metal, and an inlet/outlet system comprising a boss with a thread to fit a valve or a fitting for filling the receptacle and for subsequently distributing the content of the receptacle.
  • the inlet/outlet system has to be integrated into the container and ensure gas tightness of the connection between the inner liner and the boss with a connection port.
  • a sealing element typically, a sealing ring
  • the tightness is ensured by securing the inner liner of the composite container within the boss construction and sealing it by means of a sealing element (typically, a sealing ring) to prevent the leaking of the content.
  • a sealing element typically, a sealing ring
  • the external part of the boss is further secured to the receptacle by being at least partially enclosed in the composite outer shell of the composite container to prevent disengaging of the boss from the composite container.
  • inlet/outlet systems known in the art typically protrude from the composite container, thereby being more prone to damage and also increasing the overall length of the composite receptacle. Furthermore, they often have a complex design.
  • WO 2013/000959 discloses a composite pressure receptacle with an inlet/outlet system, having the features of the pre-characterizing portion of the independent claim.
  • the aim of the present invention is to provide a design of an inlet/outlet system for composite pressure receptacles which could limit the size of the receptacle by embedding the inlet/outlet system within the composite shell, while maintaining a simple, cost-effective construction.
  • the present invention provides a composite pressure receptacle as defined by claim 1.
  • the second part of the plug may preferably further be equipped by a flats or splines to prevent its rotation in a composite shell.
  • the aim of the collar is to provide an optimal shape to an inner liner and support it in a zone where sealing is located. Its further aim is to form a "wall" against which the inner liner can be sealed by the sealing element(s).
  • the collar may preferably be made of thermoplastic by injection molding.
  • the boss assembly can be equipped with a labeling ring.
  • the ring may also ensure proper fiber placement around cylinder neck. In the first embodiment it prevents rotation of the plug and thus allows installation of valve.
  • the inner liner is made of metal, such as steel, or of polymeric material, such as polyethylene or polyethyleneterephtalate.
  • the design of the invention allows to embed the inlet/outlet system within the composite container.
  • Fig. 1 shows a composite pressure receptacle comprising an inner liner 1 , an outer composite shell 2 , and an inlet/outlet system 3 .
  • the inlet/outlet system 3 comprises ( Fig. 2, 3 ):
  • the second part of the plug 6 has a smaller diameter than the third part of the plug 6 , thereby forming the fitting means.
  • the disc 5 adjoins the second part of the plug 6 .
  • the recess in the first part of the plug 6 has a smaller diameter than the second part of the plug 6 , and receives the end parts of the composite shell and optionally also a labeling ring 4 .
  • the second part of the plug 6 may preferably further be equipped by a flats or splines to prevent its rotation in a composite shell.
  • the composite pressure receptacles provide with a boss according to the present invention can be used for storage and transportation of fluids and gases under low or high pressure, such as LPG, CNG, industrial gases or air.
  • the described design is particularly suitable for fully wrapped composite cylinders.
