What do the high-pressure and low-pressure ends of a turbine’s steam seal refer to? I don’t quite understand it; I hope friends can help answer it~

What do the high-pressure and low-pressure ends of a turbine’s steam seal refer to? I don’t quite understand it; I hope friends can help answer it
The intake side is the high-pressure side; the pressure drops after work is done, while the outlet side is the low-pressure side! The steam seal on the high-pressure side prevents steam from escaping, while the one on the low-pressure side prevents air from entering!
The side of the cylinder adjacent to the hydraulic actuator is the high-pressure side, while the side adjacent to the coupling is the low-pressure side
The low-pressure side is 1.0 MPa steam; air can’t get in there, right?
Yours is a back-pressure turbine, while ours is a fully condensing type; the exhaust from the turbine is under negative pressure, so if there’s no shaft seal air, it will be drawn into the turbine!
