摘要: A high temperature actuated steam valve is disclosed that has a connector extending between the casing of the valve and its actuator. The connector can include two spacers made of materials each with a different hot strength wherein the first spacer, fixed adjacent the casing, has a higher hot strength that the second spacer, which is fixed adjacent to the actuator.

摘要: A steam turbine is provided having a relief groove which is arranged in the region of the equalizing piston and extends in the circumferential direction of the rotor. The relief groove, with regard to an inlet passage, is arranged in the axial upstream direction so that it is arranged on the rotor outside a region in which the steam flow enters the bladed flow path via the inlet passage. The relief groove, with regard to the first blade row, is arranged in a region in which the greatest thermal stresses can arise in the rotor. As an option, the relief groove has a cover for reducing vortex flows, and also devices for reducing heating of the groove or devices for active cooling. The steam turbine allows an increased number of risk-free running up and running down operations of the steam turbine with minimum detriment to the turbine performance.
