Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In Fig. 1: 1. turbine chamber, 2. the first bolt, 3. the first rubber strip, 4. supporting ring, 5. upstream extremity fixed pressure ring, 6. primary seal, 7. downstream fixed pressure ring, 8. the second bolt, 9. foundation ring, 10. the second rubber strip, 11. the 3rd bolts, 12. guide plates, 13. the 4th bolts.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not the restriction to the utility model protection domain.
As shown in Figure 1, fixed sealing expansion joint structure is installed in a kind of inner side, comprises supporting ring 4, primary seal 6, upstream extremity fixed pressure ring 5, downstream fixed pressure ring 7 and guide plate 12.Supporting ring 4 is in " L " shape, its side is fixed on foundation ring 9 by the 3rd bolt 11, another side is fitted in turbine chamber 1 and primary seal 6, is provided with the first rubber strip 3 between supporting ring 4 and turbine chamber 1, is provided with the second rubber strip 10 between supporting ring 4 and foundation ring 9.
The upstream extremity of primary seal 6 is fixedly connected with turbine chamber 1 with the first bolt 2 by upstream extremity fixed pressure ring 5, and the downstream of primary seal 6 is fixedly connected with foundation ring 9 with the second bolt 8 by downstream fixed pressure ring 7.Guide plate 12 one end is fixed on turbine chamber 1 by the 4th bolt 13, and the position of guide plate 12 the other end is corresponding with the position of foundation ring 9.
First bolt 2 is successively through fixing after turbine chamber 1, the upstream extremity of primary seal 6 and upstream extremity fixed pressure ring 5, and the second bolt 8 is successively through fixing after the downstream of downstream fixed pressure ring 7, primary seal 6 and foundation ring 9.
Primary seal of the present utility model can make whole coil structures, can overhaul, easy construction inside runner to primary seal.
The beneficial effects of the utility model are, primary seal two ends all adopt pressure ring, bolt is separately fixed at runner envelope and on foundation ring, have good followability thus sealing effect not with the vibration of runner envelope, distortion and changing, avoid the appearance of water turbine slip joint water leakage situation, be conducive to unit safety operation.
