Definitions

  • the present invention relates to a valve disk according to the preamble of Claim 1.
  • Such a valve disk is known from DE 33 17 809 A1.
  • valve disk on the one hand form a closure for a container and on the other to accommodate a valve, are mounted on containers, which are filled with a pressurized medium.
  • the present invention is therefore based on the object, a valve disc the generic type to develop so that an unwanted outflow is excluded from preferably gas from the filled container.
  • sealing layer With the help of between two spacers over the entire surface arranged sealing layer becomes the existing micro-space formed by the surface roughness so hermetically filled that the passage of gas molecules is excluded.
  • the new valve plate has properties as a one-piece part, without the particular manufacturing advantages that the production of several Lifts brings with it, restrict.
  • the new valve disk is so dense that no measurable Gas leakage is observed.
  • a film may be provided which on one side the two blank pieces is applied before deformation.
  • a plastic film a use self-adhesive, for example polypropylene, with a metal sheet, from which one layer of the cut pieces is made, is coated.
  • the sheet can also be coated with a rubber coating be in both cases by the deformation or the deformation forces at the production of the valve disk, the respective sealing layer practically in the existing surface depressions flows.
  • the sealing layer in an initially liquid form, For example, as a paint or as a suitable plastic, which harden after the order and fill in the surface depressions.
  • the order will be to a plate dome together deformed dish layers placed in a corresponding dip. Due to the capillary effect, the liquid substance enters the microinterspace and then harden. Prerequisite is a correspondingly low viscosity of Substance.
  • the solution of the object of the invention according to claim 2 makes itself exploit that in principle formed of sheet metal, superposed cut pieces tinned.
  • the plate dome is a fusion of the tin layers, creating a gas-tight Composite is produced between the blanks.
  • the sealing layer is joined together by welding in the sense of welding Tin layers formed.
  • Heat application of the valve disk for the purpose of melting the Tin layers are sufficient in a partial area of the valve disk, which, however, is extends over the full circumference, so that a hermetic seal in the outflow direction the gas is guaranteed.
  • the invention is to be realized with little manufacturing effort, What is significant in that, as such valve disk in very large Quantities are produced.
  • the valve disk shown in Figure 1 consists of a total of two plate layers, and Although from an inner plate layer 1 and an outer plate layer. 2
  • the valve disk is formed by jointly deforming two blank pieces, between which a sealing layer 6 is arranged.
  • This sealing layer 6 may be provided on both plate layers 1, 2, as This is the case, for example, when using a tinned sheet.
  • sealing layer 6 on one of the two plate layers 1, 2 be applied, but in any case on the side of a plate layer 1, 2, the other is facing.
  • Such a sealing layer 6 is, for example, as a gas-tight plastic or applied as a rubber coating, which after deformation to the valve plate the existing surface depressions of the plate layers 1, 2 in the contact area at least largely fulfilled.
  • This effect is achieved by filling in existing surface depressions 7 the dish layers 1, 2 reached, so that no gas from the inside of the container can happen.
