Definitions

  • the invention relates to a pressure vessel according to the preamble of claim 1 or claim 2.
  • Such pressure vessels are known and are used in a wide variety of applications, for example for the reception and storage of so-called 2-component products, used.
  • Important for pressure vessels to hold such products is that the products can be stored in it for long-term stability.
  • the products are also used for a period of several Can be stored in the pressure vessel for months to a few years, without the risk that the pressure is released or that the components react chemically under the influence of air humidity and / or oxygen.
  • valve plate together with the Dispensing valves are made from a material that prevents the im Glue the pressure vessel components to the dispensing valves stay and clog them.
  • the valve plate is made of one material poor adhesive properties exist, so it is difficult to valve plate to seal long-term, since such a valve plate has so far hardly been used could be glued.
  • a reliable, long-term stable sealing is however with generic pressure vessels indispensable.
  • Embodiment proposed using the sealing surfaces of the dispensing valves To coat silicone improves the sealing behavior between valve plate and dispensing valves improved, since that is relative Adapt soft silicone to any unevenness in the surface of the valve plate can.
  • silicone has a low adhesion, so that in the pressure vessel components do not stick to the dispensing valves.
  • Valve plate on its underside a substantially hollow cylindrical Has extension on which a forming a chamber, a hollow cylindrical Containing neck portion container is attached, the extension on the outside is provided with a raised, cylindrical section which has an annular groove in which another O-ring is received which seals the container at the neck portion.
  • the pressure vessel has a metal housing 1, which forms a first chamber in its interior, in which a liquid or semi-liquid component K1 is received.
  • An insert 2 is inserted into the metal housing 1 from above, on which an overall dispensing device designated 11 is supported.
  • This delivery device 11 comprises a valve plate 3, which is fixed to the insert 2.
  • a second, inner metal container 10 is fastened, in which a second liquid or semi-liquid component K2 is received.
  • an O-ring loaded by a tension ring is provided, or the insert 2 is coated with an adhesion promoter to improve the seal between the valve plate 3 and the insert 2.
  • the valve plate 3 is provided with two through bores 6, 7, into each of which a dispensing valve 8, 9 is inserted.
  • the dispensing valves 8, 9 are designed to be elastic and in one piece in the longitudinal direction.
  • an actuating element 12 is provided, which is provided on the underside with two tubular connecting pieces 14, 15 which extend to the bottom of holes drilled into the dispensing valves 8, 9.
  • the valve plate 3 has on its underside an essentially hollow-cylindrical extension 18, to which the inner container 10 is attached.
  • the insert 2 is airtightly connected to the metal housing 1 on the top by crimping 19.
  • the valve plate 3 consists of a non-adhesive plastic, preferably a polyolefin such as polypropylene, or a halogenated polyolefin. Under non-adhesive plastic "is understood to mean any plastic to which the pressure vessel contents do not stick in visible amounts.
  • insert 2 is together with the valve plate 3 and the actuating element 12 is shown in an enlarged view.
  • the circularly trained On its underside, insert 2 essentially has a cross section U-shaped edge 20 on the inner, free leg 21 of the edge 20 is embedded in the valve plate 3 such that a cavity 22 between the Valve plate 3 and the insert 2 is created.
  • This cavity 22 there is an O-ring 4 used, which is loaded by an annular clamping ring 5.
  • the clamping ring 5 is fixed in the insert 2 by a plurality of bulges 24. These bulges 24 are generated by plastic deformation of the insert 2.
  • the clamping ring 5 during the attachment of the bulges 24 is preloaded with a certain force, so that the O-ring 4 a takes oval shape and seals on the outside of the valve plate 3 and the inside of the insert 2 and the valve plate 3 against the interior of the pressure vessel seals reliably and with long-term stability.
  • the width of the Cavity 22 is preferably slightly larger than the diameter of the O-ring 4 in the unloaded state. As a result, the insertion of the O-ring 4 in the cavity 22 facilitated.
  • the extension 18 is on the outside with a raised, cylindrical extending portion 29 provided, the annular groove 30th has, in which a further O-ring 31 is received.
  • the inner metal container 10 has a corresponding to the cylindrical section 29, hollow cylindrical neck portion (not shown) to which the O-ring seals creates.
  • the extension is with a Provided external thread 32 on which the inner container with a corresponding Internal thread can be screwed.
  • Fig. 3 shows an alternative embodiment to that shown in Fig. 2, from one O-ring and a clamping ring 5 existing seal between insert and Valve plate.
  • a polyurethane composition is preferably used as the adhesion promoter 13 used, which in addition to good adhesion-promoting properties is permanently elastic.
  • the layer thickness of the applied adhesion promoter 13 is preferably about 2 to 20 microns.
  • Pressure vessel is universal in terms of the components to be accommodated applicable. It also prevents the pressure in the container from reducing or that the components ingested with oxygen and / or humidity Come into contact. As a result, such containers are particularly suitable for long-term stable storage of the recorded components.
