The flow of steam into a steam-collecting space of a steam turbine is controlled with a steam-inlet valve. The novel steam-inlet valve has an especially high control performance and losses of steam are kept especially low. The steam-inlet valve has a rotary cylinder that forms a shut-off member. The rotary cylinder is placed in a housing, and a steam inlet can be connected to a steam outlet via a passage provided in the peripheral surface of the rotary cylinder.
1. A steam-turbine plant, comprising:a steam turbine; a steam-collecting space with an inlet side upstream of said steam turbine; a steam-inlet valve disposed to control a flow of steam into said steam-collecting space at said inlet side; said steam-inlet valve having a housing formed with a steam inlet and a steam outlet, and a rotary cylinder disposed in said housing and forming a shut-off member, said rotary cylinder being formed with a passage enabling a connection between said steam inlet and said steam outlet.
