POSSIBILITY OF DAMPING PRESSURE PULSATIONS IN BALANCING CONTROL VALVES
Abstract eng: The cone shape alterations are given for balanced control valves of steam turbines and their influence is assessed on the flow field in the valve outlet diffuser. Suitable solutions are searched for, which will guarantee the stability of the boundary layer on the diffuser wall in all operating modes of the turbine. It is verified whether using steam flow from the bypass valve can prevent separation of the main steam flow from the diffuser wall. Various variants of the steam outlet from the valve cone are considered.
