Abstract:
The present invention discloses an elastic sheet used for a turbine follow-up suspended steam seal belt and a steam seal structure thereof, which comprises a plurality of elastic L-shaped metal sheets correspondingly overlapped on the same rim, one rim of the L-shaped metal sheet is a toothed rim, the toothed notches of the toothed rim extend laterally through the entire toothed rim so that the other rim of the L-shaped metal sheet can be bent longitudinally toward the toothed rim to form an arc shape; the toothed notches and the toothed tabs of the toothed rims of the plurality of L-shaped metal sheets are misoriented with each other to cover the toothed notches, and the other rim of the L-shaped metal sheet is fixed within the arc-shaped steam seal ring block along the steam seal ring teeth, the steam seal ring teeth extend out from the top of the toothed rim to seal the gap between the seal ring teeth and the turbine main shaft, and the toothed rims of the L-shaped metal sheet perform elastic beating reciprocately down after being subjected to the force at the top; the invention has the advantages of simple structure and the sealing of the main shaft side is well achieved; and the main shaft of the turbine can be completely achieved by utilizing the elastic characteristics of the seal elastic sheet of the invention.

Claim (Index 12):
The follow-up suspended steam seal structure according to  claim 9 , characterized in that the thickness of the metal sheet is from 0.2 mm to 1 mm.
