A control valve for controlling a gaseous volumetric flow rate, in particular a steam volumetric flow rate, having a valve housing, a valve seat, and a valve throttle element which can be moved relative to the valve seat along a movement axis. The valve housing shapes the valve seat, and the movable valve throttle element has a throttle edge region which interacts with the valve seat. The control valve has multiple volumetric flow rate swirl elements which interact with the throttle edge region and which prevent or at least reduce shear layer instabilities in a shear layer between a wall jet region of the gaseous volumetric flow rate and a core flow region of the gaseous volumetric flow rate.

Regulating valve and turbine

A structure and method are provided for preventing or at least minimizing thermally-induced structural distortions, such as may occur when a steam turbine is cooling down. The steam turbine may include an inner housing and an outer housing. An intermediate space is formed between the inner housing and the outer housing, and sealing steam may be injected into the intermediate space to avoid the formation of temperature strata in the interspace and thus prevent the outer housing from bowing.

Method for a temperature compensation in a steam turbine

A diversion station is provided. The diversion station makes it possible to particularly effectively cool diverted water vapor by mixing it with water. The diversion station includes a mixing device, which comprises a so-called static mixer that is substantially made of a wire mesh. The wire mesh is produced by at least one wire that is substantially interlaced into loops. In the intended installation situation, the mixer is installed upstream of a water injection with regard to a flow direction specified by the water vapor such that the mixture of water and water vapor flows through the loops.
