Definitions

  • the invention relates to a sealing system comprising a cylindrical tube of a material that is capable of deformation under the influence of a temperature increase, and a gasket of an at least partially elastic material for sealingly retaining the tube in a lead- through housing coaxial with the tube by forming a collar therearound in a circular space, and also to the gasket as such.
  • Sealing systems of this kind are already known from N - A-177516 in the name of the present applicant. Said application relates to a plug which is dividable in longitudinal direction.
  • Expandable collars exhibiting a sealing action in the event of a fire are already known per se from international patent application WO 97/04838.
  • the collar used therein is a pressed-on collar, however, which comprises a fixed housing in which an expandable material is present, which collar is fixed to a vertical wall at the end of the lead-through housing.
  • Such a pressed-on collar is not suitable for being sealingly inserted into a circular space that is formed between the lead-through housing and the tube that extends therethrough.
  • the effect of a sealing system according to the invention is that an increase of the ambient temperature, at least to a temperature at which the tube will deform and soften, will result in an expansion reaction of the gasket material.
  • the temperature range within which the expansion reaction of the gasket takes place is above the temperature range within which deformation or softening tube occurs. The required insertion force will be smaller when the tube has already softened, of course, and it will be obtained with a smaller amount of expandable material .
  • the collared tube will be compressed as a result of this expansion reaction, as a result of which the entire passage (through the tube and through the housing) will be closed, and the lead-through housing will be filled by the plug thus being formed, because the expanded gasket will fill at least a complete cross-sectional area on the lead-through housing and the tube.
  • This is in particular advantageous in the event of a fire, since transport of mediums such as gases and liquids through the lead-through housing or through the tube will not be possible any more.
  • the invention relates to a sealing system wherein the tube is made of a plastic or a composite material, for example consisting of a plastic layer- aluminium layer-plastic layer. Tubes of this kind are flexible and the gasket is likewise partially elastic as a result of its composition, so that tube bends can likewise be sealed.
  • a second aspect of the invention relates to a gasket for the aforesaid sealing system.
  • a gasket according to the invention is made of a cross-linked material, for example a rubbery linear polymer, wherein the expandable material is graphite, which is present in an amount of 5 - 25 % by weight.
  • said weight percentage is 12.5. This composition ensures an adequate sealing action at usual temperatures of 15 - 50 °C as well as a suitable expansion at higher temperatures, for example upwards of 50 °C.
  • Zinc oxide (ZnO) 5 Stearic acid 1
  • Figure 1 shows the sealing system at a usual prevailing temperature
  • Figure 2 shows the sealing system of Figure 1 at a higher temperature .
  • the sealing system 1 is made up of a tube 2, which tube extends through a co-axial lead-through housing 3, and a gasket .
  • Gasket 4 is made up of two longitudinal halves, whose plane of division coincides with the plane of the sectional view in the drawing.
  • the longitudinally dividable gasket 4 collars tube 2 with a fixed clamp at the location of the two circular spaces 6.
  • gasket 4 includes two kinds of ribs, viz. outer, angular ribs 8 and inner trapezoidal ribs 9.
  • deformation commences at temperatures which are generally lower than the temperature at which the expansion reaction commences .
  • the deformation temperature for PVC is about 80 °C, for PE about 110 °C and for PP about 150 °C.
  • the optimum temperature for the expansion of expandable graphite is about 200 °C. At this temperature the tube as such will have softened to such an extent that said clotting can take place even more forcefully due to displacement and crushing of the tube in the lead- hrough housing. In fire conditions these temperatures are always exceeded, however.
