Definitions

the invention relates to a steam turbine Regulation of live steam inflow.
Steam turbines with nozzle group control are known, at which the first turbine stage, too Called control stage, the steam turbine with a plurality of pressurized sectors, their steam inflow adjustable by a special control valve is. In such steam turbines, at least three or more control valves available.
Steam turbines without nozzle group control are also known or without control level. Such steam turbines are up to 180 MW with min. a control valve until 600 MW with two control valves and over 600 MW with four Control valves built.
the turbine housing of steam turbines with Control stages are constructed differently than the turbine housing of steam turbines without control stage.
the invention is based on the object a reduction of the cast models and the modules, in particular for the turbine casing and thereby lower To achieve set-up times and lower costs.
this is achieved by that on a steam turbine with or without control stage the Number of control valves for regulating the fresh steam inflow is the same, with at least two control valves are, and that the turbine outer casing at least in Area of the live steam inlet section of a steam turbine structurally identical with or without control stage is.
the high pressure steam turbines shown in FIGS. 1 and 2 consist of two housings, the outer housing 1 and the inner casing 2.
the turbine runner is not shown.
the outer housing 1 consists in each case from an upper housing part 3 and a lower one Housing part 4, the horizontal flange connection are interconnected.
the one stored in the outer housing Inner housing is also separated horizontally and has an upper housing part 5 and a lower housing part 6.
valve body block 7 In the steam turbines shown in FIGS. 1 and 2 are in a valve housing block 7 two control valves 8, 9 and a quick-action valve 10 are combined.
the valve body block is over the body of the Control valve 8 by means of a flange connection on the side upper outer housing part 3 attached.
One with the outlet of the control valve 8 connected connecting pipe 11 extends into the upper part of the outer housing and opens laterally into the interior of the inner housing 2.
the outlet of the control valve 9 is with the one leg of a downward and U-shaped bent connecting line 12 connected to her another leg on one on the lower outer housing part 4 flanged intermediate piece 13 is welded.
the Connection line 12 opens into a with the intermediate piece 13 connected connecting pipe 14.
the connecting pipe 14 extends into the lower housing part 4 of the outer housing and flows into the interior of the Inner housing 2.
the quick-action valve 10 has the task in the event of a rapid fire, the steam supply to the control valves 8 and 9 and thus to interrupt the turbine. It is as Security body designed and is not by one shown servo motor operated.
the two control valves 8 and 9 are used for Regulation of the steam flow. They are not represented by hydraulic actuators actuated.
the steam turbines according to FIGS. 1 and 2 differ in that the steam turbine according to Fig. 1 has a control stage and the steam turbine according to Fig. 2 is designed without a control stage.
the same valve housing block 7 is present, which is also in the same way on the turbine outer casing is flanged. Thanks in particular to the fact that for both types, i.e. Type with or without control stage, the same number of control valves is present and their connection arrangement and connection with respect to the Outer housing 1 and the inner housing 2 designed the same is a reduction of cast models and a reduction achieved by modules. This enables, in particular the outer housing 1 and also the valve housing block with the connections for both types of steam turbine structurally the same.
Fig. 1 With the steam turbine with control stage according to Fig. 1 are the inlet channels or nozzle boxes 15, 16 in Inner housing 2 integrated. That the nozzle boxes 15, 16 in Control wheel downstream of the steam flow direction is not shown.
the inlet channels or nozzle boxes 15, 16 are separated from each other by two partitions 17, 18, that the nozzle box 15 has a larger sector and thus a larger passage area for the live steam forms as the nozzle box 16.
Control valve 8 opens opens into the nozzle box 15 and control valve 9 from above from below in the nozzle box 16.
the two control valves can be different large openings adapted to the nozzle segments be provided.
Each control valve is independent in Opening and closing directions can be actuated.
the live steam becomes the valve housing block 7 supplied, it flows through the quick-action valve 10 and reaches the control valves arranged one behind the other 8, 9. After the control valves 8, 9, the steam is the Nozzle boxes 15, 16 and the nozzles, not shown Control stage fed.
the inner housing has no nozzle boxes. It there is also no control wheel. Are accordingly in the inlet section of the inner housing 2 also no partition walls 17, 18 present, so that a single annulus 19 is formed, the live steam over the two Control valves 8, 9 is supplied. Otherwise correspond the components of the steam turbine without control stage according to the Fig. 2, the components of the steam turbine shown in Fig. 1 with control level. Accordingly, the same components have the same reference numbers and it will in this regard, reference is made to the above description.
the high pressure steam turbines shown in FIGS. 3 and 4 differ in type and Way of construction and connection of the valve housing block. Otherwise, there are those shown in FIGS. 3 and 4 Steam turbines also from two housings, the outer housing 101 and the inner case 102.
the outer case consists of an upper housing part 103 and a lower housing part, not shown, the with flange connection, not shown, with each other are connected.
the inner housing stored in the outer housing is also separated horizontally and has one upper housing part 105.
the lower part of the inner casing is also not shown.
the steam turbines shown in FIGS. 3 and 4 each have a valve housing block 107, in which two Control valves 108, 109 and a quick-action valve 110 are installed.
the valve housing block 107 is on the Outer housing upper part 103 put on and by means of double Flange connection connected to this.
One with each connecting pipe connected to the outlets of the control valves 108, 109 111, 114 extends into the upper part 101 of the outer housing and opens into the Interior of inner housing 102.
the task and function of the quick-action valve 110 and the control valves 108, 109 is the same as in the steam turbines according to FIGS. 1 and 2. Die Differences and similarities of the steam turbines according to 3 and 4 are also the same as regarding the Steam turbines according to FIGS. 1 and 2. It is therefore in this relationship referred to the above statements.
the two types are different of the steam turbines with control stage according to FIG. 3 and without Control stage according to FIG. 4 in turn only a partial area of the inner case, due to the presence or the absence of the control level.
At the steam turbine 1 are in the inner housing 102 integrated nozzle boxes 115, 116 in turn through partitions, of which only those in the upper part of the inner housing partition 117 located is shown, separated from each other so that the one nozzle box one larger sector and thus a larger passage area forms for the live steam than the other nozzle box.
load points and training and mode of operation of the control valves and the live steam supply the statements already made for Fig. 1.
the turbine outer casing, the valve assembly and Parts of the inner casing for both a steam turbine certain types with and without a control level because they are structurally the same and in Size and shape match.
control valves of the valve assembly have generally equal openings. In special cases however, they can also have differently sized passage openings exhibit.
the same cast model can be used for the outer case for turbines, with and without control stage become.
valves and valve dispositions can be used for turbines with and without control stage be used.
FIG. 5 shows the upper part of a cast model 120 from above, with inserted cores 121, 122 and 123, that for the manufacture of the upper outer housing part a steam turbine according to FIG. 3 or FIG. 4 is used.
