Definitions

  • the enclosure E is of revolution around the axis A2 of the pipe and slides along the latter while turning on itself. It carries for example 40 nozzles B. These slide along their longitudinal axis A1 and therefore perpendicular to the axis A2, in the wall of the enclosure, thanks to an O-ring seal B2. The seal is placed on a suitable diameter to adjust the contact force to a suitable value.
  • the housing of the nozzles in the wall of the enclosure forms a stop B3 limiting the movement of the nozzle to the outside.
  • the enclosure E has a diameter slightly smaller than that of the pipe, and it is introduced into the latter before it is pressurized, which allows the retraction of the nozzles towards the interior of the enclosure.
  • the minimum water passage section in the nozzle B provided with its deflector D is less than 100 mm to obtain a high erosion yield.
  • the nozzle B can be made of brass
  • the outlet diameter of its nozzle T can be 8 mm
  • the deflector D can be made of brass and have a diameter of 10 mm and a thickness of 1 mm, the water passage section to the right of the active edge D2 being 1 mm high.
  • the invention can be implemented not only with axial jet nozzles of circular section, but also with dihedral shaped nozzles forming a laminar jet, using the device shown in FIG. 4.
  • the nozzle B 'then extends, perpendicular to the plane of this figure, over a width much greater than its thickness, the latter alone being shown, the shape of the nozzle T', of the deflector D'and of the guide profile G 'remaining constant over the entire useful width of the nozzle, and forming a rectilinear active edge D'2 and a bearing surface D'1.
  • Nozzle support fins are shown in G'1.
  • the nozzle B ' is constituted by two cylindrical blocks (not of revolution), with generatrixes perpendicular to the plane of the sheet. One of these blocks forms at its lower part the guide profile G ', and the other, at its lower part also, the deflector D'. These two blocks are joined by end plates 4.
