Turbine assembly and method for assembling a turbine

摘要

According to one aspect of the invention, a turbine assembly includes a first stationary component, a second stationary component positioned radially outside the first stationary component, a first key feature on the first stationary component configured to mate to a second key feature on the second stationary component and a seal assembly positioned between the first and second key features to reduce fluid flow between the first and second key features. The seal assembly includes a V-shape member and a second member adjacent to the V-shape member, the second member and V-shape member having different rates of thermal expansion. The seal assembly also includes a latch feature coupled to the V-shape member configured to expand the seal assembly from a compressed state to an expanded sealing state when the seal assembly is subject to an elevated temperature.

1. A turbine assembly comprising:
a first stationary component; a second stationary component positioned radially outside the first stationary component; a first key feature on the first stationary component configured to mate to a second key feature on the second stationary component; and a seal assembly positioned between the first and second key features to reduce fluid flow between the first and second key features, the seal assembly comprising:
a V-shape member;a second member within the V-shape member, the second member and V-shape member having different rates of thermal expansion; anda latch feature integrally formed with the V-shaped member configured to expand the seal assembly from a compressed state to an expanded sealing state when the seal assembly is subject to an elevated temperature, wherein the expanded sealing state causes the seal assembly to contact substantially parallel radial surfaces on the first and second key features.
