PROTECTIVE SCREEN AND ITS INFLUENCE ON THE RELIABILITY OF THE CONTROL VALVE OPERATION
Bednář L., Tajč L., Miczan M.
pages 17 - 28, full text

The standard version of the control and stop valve of steam turbines is mentioned. The pressure loss caused by the screen at the valve entrance is assessed. The results of different experiments and the 3D numeric simulation are presented. The influence of the screen on the loss, the suitability of the direction openings and the input spin of the flow in the valves is described. The pressure loss in the combined valve and the influence of the screen on even distribution under the valve cone is mentioned
