Definitions

  • the present invention relates to a rotating jet nozzle of the type consisting of a static body delimiting an open cavity housing an injector.
  • one end of the injector is driven in circular displacement around a pivot of the body under the effect of a tangential flow water pressure acting on said injector while the other end of this injector, provided with a nozzle, is housed in the opening of the cavity shaped as a concave seat allowing the precession movements of the injector.
  • Such nozzles may in particular be used in the case of cleaning installation. Until now, these rotating jet nozzles can not be fed with fluids at medium pressure because of the dimensional characteristics of these nozzles.
  • An object of the present invention is therefore to provide a nozzle whose dimensional characteristics allow a supply of such a nozzle by means of a fluid flow under medium pressure, that is to say having a pressure generally between 20 and 60 Bars.
  • the invention relates to a nozzle of the aforementioned type, characterized in that the inner diameter of the nozzle is in the range of 2.8 to 6 mm while the smallest inside diameter of the seat is included in the range from 4 to 11, 5 mm, the internal diameter of the seat being 1, 7 times larger than the inner diameter of the nozzle to ⁇ 10%, so as to allow a supply of medium pressure nozzle.
  • the rotating jet nozzle referred to as a rotary nozzle, which is the subject of the invention, represented by the general reference 1, is more particularly intended to be installed in medium pressure pumping installations.
  • This nozzle consists of a static frusto-conical body 2A delimiting an open cavity 2B housing an injector 2C.
  • This injector 2C is in the form of a cylindrical body provided with a through axial duct.
  • One end of the injector 2C is driven in circular displacement around a 2D pivot of the body 2A under the effect of a tangential flow water pressure acting on said injector 2C.
  • the other end of this injector 2C is provided with a nozzle 2E.
  • the nozzle 2E has the shape of a tubular body provided with a through axial duct. One end of this body is bulged to delineate a convex jet head. The proximal face of this bulge constitutes an axial abutment during the fitting of the nozzle 2E in the axial duct passing through the injector 2C.
  • This end of the injector 2C, provided with a nozzle 2E convex head, is housed in the opening of the cavity 2B shaped as a concave 2F seat allowing the precession movements of the injector.
  • the nozzle 2E intended to bear against the walls of the concave seat 2F, has rounded portions giving the nozzle head a general shape of a half-sphere, the movements of the nozzle 2E inside the seat 2F are facilitated .
  • the inside diameter d1 of the nozzle 2E is in the range of 2.8 to 6 mm while the smallest inside diameter of the seat 2F is in the range of 4 to 11.5 mm.
  • the smallest inside diameter d2 of the seat is 1, 7 times larger than the inside diameter d1 of the nozzle to ⁇ 10% so as to allow a medium pressure supply of said nozzle.
  • the seat 2F is formed by means of an insert in the opening of the cavity 2B, this opening of the cavity 2B constituting the jet expulsion orifice medium pressure of the nozzle.
  • the seat 2F has the shape of a hemispherical bowl open at its base to delimit a discharge passage of the fluid flow, the diameter of the evacuation passage of the fluid flow of the seat corresponding to the smallest inside diameter d2 mentioned ci -above.
  • the seat 2F has a hemispherical bowl shape, the bottom of the hemispherical bowl opening into a second generally hemispherical cavity, the bases of the hemispheres tangent so as to delimit a generally shaped fluid passage. of diabolo.
  • the nozzle 2E and the seat 2F are made of a material, such as carbide, of greater hardness than the constituent materials of the body 2A and the injector 2C of the nozzle to reduce wear of the assembly.
