Definitions

  • Output is usually taken from our preferred pumping apparatus through a flexible tube or pipe and we have found it to be advantageous for such a tube or pipe to be terminated by a nozzle that substantially reduces in cross-section from said tube or pipe to final exit from the nozzle.
  • a nozzle that substantially reduces in cross-section from said tube or pipe to final exit from the nozzle.
  • Such provision aids maintenance of an air stream with well and evenly distributed entrained mineral fibre.
  • the stream must speed up through the nozzle, which leads to a tendency for unwanted compaction of the delivered insulation material, especially when a cavity to be filled substantially entirely nears its full state. For cavity walls, that can even lead to localised damp transmission between its skins at least in regions adjacent to delivery positions.
  • venting is also advantageous for the venting to be via a variable orifice, such as a suitable valve, preferably a gate valve.
  • a suitable valve preferably a gate valve.
  • operators can set the vent orifice to suit particular conditions on site and/or as desirable to suit different lengths of nozzle ends depending, for cavity wall filling, on the thickness of the wall skin to be penetrated, usually via a suitable sealed coupling or other sealing arrangement.
  • a nozzle 10 comprises a main part 11 having an entry section 12 of substantially constant cross-section, actually 50 mm circular, for securement thereto of flexible tube or pipe (not shown), say by clamp means such as Jubilee clips. Beyond the section 12 the nozzle part 11 tapers 13 at a constant rate to a coupling 14 for a nozzle end part 15 also of substantially constant cross-section, actually 22 mm circular, matching the end of the tapered section 13 of the main part 11.
  • venting valve 40 On the end of the branch 32 is a venting valve 40, shown diagrammatically but actually a gate valve capable of adjustably varying the effective orifice of the vent.
