  • the invention relates to a turbomachine, which is associated with at least one nozzle housing, which is arranged in a housing of the turbomachine, wherein the housing of the turbomachine has at least one live steam inlet, and wherein the nozzle housing has a corresponding to the at least one live steam inlet neck, wherein on the one hand Nozzle housing and on the other hand, the housing of the turbomachine connecting elements are assigned such that the nozzle housing is positively connected in the assembled state with the housing of the turbomachine.
  • the nozzle housing is welded directly into the turbine housing.
  • This solution has proven itself to the effect that the welded joint is absolutely tight, which also advantageously no so-called buoyancy forces arise as in piston ring seals.
  • the buoyancy forces are caused by a pressure difference between the live steam pressure and the Radschtik in the turbine housing. This additional force must be considered disadvantageously in the interpretation of the parting screw by lowering the permissible Radcrotikes.
  • a major disadvantage of the welding connection of the nozzle housing with the turbine housing is the fact that a separate and less expensive production of the Nozzle housing and the turbine housing is not possible; because the nozzle housing has a direct connection to the environment. Therefore, the nozzle housing must be sealed according to current standards before welding, in particular welded and a separate water pressure test be subjected to determine whether the nozzle housing is sealed as a whole. Thereafter, the nozzle housing is welded into the turbine housing, wherein the weld is subjected to a subsequent heat treatment. However, this includes a further transport path to the heat treatment device, so that this workflow involves a great logistical and time-consuming.
  • the nozzle housing is made as a separate component and sealed by piston rings to the turbine housing.
  • This solution has proven itself to the effect that a cost and time-saving production on separate processing machines is possible; because the nozzle housing is now a complete inner component of the turbine housing, so that the nozzle housing no additional, separate water pressure test must be subjected.
  • the above-mentioned buoyancy force is seen, which must be additionally absorbed by parting screws and thus reduces a possible pressure in the wheel chamber.
  • a further disadvantage is that a separate pressing of steam applied to the steam feeds and the wheel chamber can only be carried out with relatively expensive devices, so-called hydro plugs.
  • Such an arrangement can in particular no forces between the To transfer nozzle group and the outer housing and is also not sufficiently tight, so that resulting pressure conditions on the nozzle group and the inner housing to a higher load on the parting joint of the outer housing.
  • the invention has for its object to improve a turbomachine of the type mentioned above, in particular a fixation of the nozzle housing in the housing of the turbomachine with simple means to the effect that the nozzle housing with much less effort, but nevertheless can be installed tightly in the turbine housing.
  • the object is achieved in that on the one hand the nozzle housing and on the other hand, the housing of the turbomachine connecting elements are assigned such that the nozzle housing is positively connected in the assembled state with the housing of the turbomachine.
  • the nozzle housing can preferably be easily screwed to the housing of the turbomachine, so that a simple but tight connection of the nozzle housing to the housing of the turbomachine is provided.

  • a circumferential step is arranged on the neck of the nozzle housing, so that external thread arranged on the neck extends approximately from its front side to approximately the step.
  • a pressure ring is connected to the neck of the nozzle housing and if connected to the housing of the turbomachine, a ring nut, so that the ring nut forms a contact surface with the pressure ring in the assembled state of the nozzle housing in the housing of the turbomachine wherein an end face of the neck of the nozzle housing forms a sealing surface with the housing of the turbomachine.
  • At least one of the connecting elements is assigned to the nozzle housing towards a sealing seam, in which case the sealing ring is preferably associated with the pressure ring in connection with the nozzle housing.
  • At least one of the connecting elements has engagement openings on its free sides.
  • a suitable tool can engage in the engagement openings in order, for example, to be able to rotate the ring nut circularly into the internal thread in a circle.
  • the connecting elements therefore consist of the external thread on the nozzle housing, in particular on the nozzle housing neck, the internal thread of the housing of the turbomachine, the pressure ring and the ring nut.
  • the ring nut is first pushed over the nozzle box neck, wherein then the pressure ring is screwed onto the external thread of the nozzle neck.
  • the pressure ring is preferably screwed to the level of the pressure neck, so that there is already a sufficiently strong connection of the pressure ring to the nozzle neck, since the pressure ring rests with its corresponding end face on the stage.
  • the sealing seam can advantageously be provided, which is preferably designed as a fillet weld. In this pre-assembled state, the ring nut is initially loosely around the nozzle neck.
  • the nozzle box is placed in this preassembled state in the housing of the turbomachine, now the ring nut is bolted to the internal thread of the housing of the turbomachine.
  • the ring nut in this case has the engagement openings, which are arranged circumferentially equally distributed on the free side of the ring nut.
  • the appropriate tool can engage to screw the ring nut circular sections in the internal thread of the housing of the turbomachine.
  • the ring nut forms a contact surface with the pressure ring, so that simultaneously with the screwing of the ring nut of Pressure ring and thus the associated with the pressure ring or screwed nozzle housing is taken.
  • the ring nut is screwed so far into the internal thread of the housing of the turbomachine that the front side of the nozzle neck on the corresponding surface of the housing of the turbomachine is tight, so that here a sealing surface is formed.
  • a total of a compound of the nozzle housing is provided to the housing of the turbomachine, which provides in particular an improved tightness than in the aforementioned solution with the piston rings available. Due to the fact that a screw connection is advantageously provided here, a simple assembly of the nozzle housing into the housing of the turbomachine can be achieved. In addition, therefore, a very cost-effective solution is provided; because a separate pressing of the nozzle housing can be omitted, which also accounts for a separate post-heat treatment of the welds. Next arise no buoyancy forces, so that the wheel chamber can be loaded with higher overall pressures.
  • Another advantage of the solution according to the invention is the fact that a separate threaded plug can be used for the separate pressing of the fresh steam-charged steam feeds and the wheel chamber.

  • the ring nut is of course again out of the housing of the turbomachine Stammschraubbar, but it may happen, of course, that the ring nut so tight due to the relatively long operating time in the housing of the turbomachine, that it is no longer solvable with "normal" force.
  • an opening is introduced, in which a suitable tool can engage in order to destroy the ring nut, so that the nozzle housing is removable from the housing of the turbomachine.
  • the inventive fixation of the nozzle housing in the housing of the turbomachine is particularly suitable for steam turbines.
  • connection partners are available in the connection direction by a movement or force in the connection direction, but are not solvable by a force against the connection direction, without that the connection partners are previously disengaged.
  • Such frictional connection is given, for example, when two mutually corresponding threads are screwed into one another.
  • a force in the connection direction for example, a screw-in to understand.
  • a force against the direction of connection is an axially acting force to understand, so that the two connection partners are only solvable, for example, when the ring nut is unscrewed from the internal thread of the housing of the turbomachine.
  • the ring nut can of course be stuck in such a way in the internal thread, that this is not solvable by a simple unscrewing from the internal thread.
