| Zusammenfassung: | The utility model relates to a stationary blade sealing structure which is used in a rotary machine. The stationary blade sealing structure is used in the rotary machine and is characterized in that the stationary blade sealing structure comprises an annular stationary blade, a stationary blade retaining ring which annularly extends on the inner side of the stationary blade, a sealing plate which is arranged between the stationary blade and the stationary blade retaining ring, and a spiral spring which is arranged on the inner side of the stationary blade and presses the sealing plate in the axial direction. The wire diameter of the spiral spring is 5.1 mm-7 mm. Accordingly, sealing of the stationary blade sealing structure can be well achieved through the spiral spring, and operation efficiency of the rotary machine is guaranteed. |
