Steam turbine steam seal: On the shrouds of the guide vanes and moving blades, radial steps are milled out. These steps, together with the steam sealing plates on the guide vane holding ring and the rotor, form an effective interstage labyrinth steam seal. Where sealing is required between the rotor and the cylinder, a steam sealing body is installed. The steam sealing body is fixed on the cylinder. The steam sealing ring is embedded with steam sealing teeth. Together with the shaft sealing teeth on the shaft, it forms a non-contact steam sealing structure, which plays a sealing role between the rotating shaft and the outer cylinder.
