When the relative position movement of outer shroud 33 and internal ring 32 is to closure state, multiple outer shroud steam flow through holes 331 are located at multiple internal ring steam flows
Gap location between through hole 323, as shown in Figure 3 a.
In this embodiment, internal ring 32 is to rotate layer, and outer shroud 33 is fixed layer, and internal ring 32, outer shroud 33 are whole coil structures,
And a number of steam flow through hole (being illustrated as circular hole), these steam flow through holes are arranged with internal ring 32, the ring wall of outer shroud 33
For circumference, in column, arranged for interval.As shown in Fig. 3 a to Fig. 3 b, internal ring 32, the ring wall of outer shroud 33 are evenly distributed with 18
Row steam flow through hole, connects when the outer shroud steam flow through hole 331 of the internal ring steam flow through hole 323 of internal ring 32 and outer shroud 33 corresponds
When, valve is opening, as shown in Figure 3 b；After internal ring 32 rotates 10 degree in this case, the internal ring vapour of internal ring 32
Opening 323 is no longer connected with the outer shroud steam flow through hole 331 of outer shroud 33, and valve is closed, as shown in Figure 3 a.
In the present embodiment, internal ring steam flow through hole 323, the columns of outer shroud steam flow through hole 331 and interval angles are only schematically drawn,
Can need to change according to the design such as valve size, channel size during actual design, and the angle of rotation required for valve switch
Can respective change.
One kind that the present embodiment is only realized in the pattern of the inlet valve in Fig. 3 a to Fig. 3 b, quantity, position etc. is possible, is not only
One or necessary selects the limiting structure it is impossible to as determination embodiment protection domain.
As shown in Fig. 4 a to Fig. 4 b, it is the third embodiment of the present invention.Sealing 31 is a cover plate 37, cover plate 37 and peace
Dress mouth 2 is fixedly connected, and outer shroud 33 is fixedly connected with lifting rod 38, and lifting rod 38 passes through cover plate 37, and lifting rod 38 drives outer
Ring 33 moves in the axial direction.
The internal ring steam flow passage of internal ring 32 is multiple internal ring steam flow through holes 323, and the outer shroud steam flow passage of outer shroud 33 is multiple outer shrouds
Steam flow through hole 331；When the relative position movement of outer shroud 33 and internal ring 32 is to open mode, multiple outer shroud steam flow through holes 331 with
Multiple internal ring steam flow through holes 323 correspond connection, as shown in Figure 4 b；The relative position of outer shroud 33 and internal ring 32 mobile to closing
During conjunction state, multiple outer shroud steam flow through holes 331 are located at the gap location between multiple internal ring steam flow through holes 323, as shown in fig. 4 a.
In the present embodiment, internal ring 32 is fixed layer, and outer shroud 33 is sliding layer.Internal ring 32, outer shroud 33 are whole coil structures,
And a number of steam flow through hole (being illustrated as circular hole), these steam flow through holes are arranged with internal ring 32, the ring wall of outer shroud 33
For circumference, in column, arranged for interval.As shown in Fig. 4 a to Fig. 4 b, internal ring 32, the ring wall of outer shroud 33 are evenly distributed with 6
Circle steam flow through hole.Connect when the outer shroud steam flow through hole 331 of the internal ring steam flow through hole 323 of internal ring 32 and outer shroud 33 corresponds
When, valve is opening, as shown in Figure 4 b；When outer shroud 33 slides axially in this case with respect to upper and lower two vapour
After one half-distance of the spacing of opening, the internal ring steam flow through hole 323 of internal ring 32 is with the outer shroud steam flow through hole 331 of outer shroud 33 not
Connect again, valve is closed, as shown in fig. 4 a.
It is used on internal ring 32, the number of turns of steam flow through hole of outer shroud 33 and spacing distance, and outer shroud 33 in the present embodiment lifting outward
Ring 33 slide the position of lifting rod 38 and quantity, be all only schematically drawn, during actual design can according to valve size,
The design such as channel size needs to change, thus the distance slided required for valve switch also can respective change.
As shown in figure 5, coreless steam turbine inlet valve of the present invention, can also be provided with internal ring 32 and enter vapour for adjusting steam turbine
Flow enter vapour adjustment structure 6.
A kind of concrete structure entering vapour adjustment structure 6 is：Enter vapour adjustment structure 6 and include the relatively-stationary adjusting set with sealing 31
62 and the adjusting rod 61 that is located in adjusting set 62, adjusting set 62 and go out to be provided with gap between vapour passage 4, adjusting rod 61 with adjust
Section set 62 seals cooperation and relatively slides along axis, and adjusting rod 61 can put in adjusting set 62, and sealing coordinates with going out vapour passage 4.
As shown in Figure 5, can be flexible in adjusting set 62 by adjusting rod 61, adjust adjusting rod 61 and go out between vapour passage 4
Gap length, thus adjust entering out throttle flow in vapour passage 4 from entering vapour passage 1, that is, adjust steam turbine enters steam flow amount.
To sum up, coreless steam turbine inlet valve of the present invention, eliminates valve core of main valve, makes the overall structure of valve simple, compact,
And the cancellation of valve core valve stem decreases valve consumptive material, and it is that the other valves of suit or part provide condition inside it, reduce
