Definitions

  • the present invention relates to a device for fixing against a tubular plate of a tube bundle heat exchanger of a perforated plate for controlling the flow rates of fluid entering the tubes.
  • the present invention aims to provide a device for fixing against the tubular plate of a perforated sheet for controlling the flow rates of fluid in the tubes, which ensures precise control of these flow rates, does not require the condemnation of some of the holes of the tube plate, but is easily removable to allow access to all of the holes.
  • the device of the invention is characterized in that it comprises hollow studs inserted and expanded in the ends of some of the tubes and ending on the external side by a threaded end, on which is screwed a nut coming to tighten by its lower face the perforated sheet against the tubular plate, and provided with a head pierced with an axial bore.
  • the axial bore of the nut is of diameter less than the internal diameter of the corresponding stud, and of a size such that it ensures the desired pressure drop at the inlet of the tube in which the stud is inserted.
  • the tubular plate 1 is pierced with holes such as 2, 3 in which are fitted tubes 4, 5 whose ends are welded to the tubular plate by weld beads 6, 7.
  • the perforated sheet 8 pierced with holes such as 9 is clamped against the tube plate using members of which only one has been shown.
  • the latter comprises a stud 10 expanded in the zone 11 against the internal wall of the corresponding tube 4, and ending with a head 12 with external thread 13, engaged inside a hole 14 in the perforated sheet of the largest diameter than the others. On this head is screwed a nut 15, of corresponding internal thread, and the lower face 16 of which tightens the perforated sheet.
  • This nut is provided with a head pierced with an axial bore 17, of diameter less than the internal diameter of the stud, and equal to that of the normal hole 9 of the perforated sheet. It can thus be seen that the fixing device avoids any circulation of fluid between the perforated sheet and the tube plate, while ensuring equal flow between the tube 5 and the tube 4 provided with the fixing member for the perforated sheet.
  • the device of the invention is applicable in particular to tubular heat exchanger plates installed in the separator-superheater devices of the steam expansion turbines of an electric power generation plant.
