FIELD: machine building. ^ SUBSTANCE: balanced control valve mainly for steam turbines consists of valve box, of valve cup, of rod of control valve connected to valve, of seat of relief valve, of seat of main valve, of protective cartridge, of packing system and of special coupling. The latter connects the rod of the valve with a rod of a servo-motor. The relief valve is rotary. ^ EFFECT: facilitation of high quality of process of control over steam flow into turbine due to elimination of free axial displacements of unloaded control valve relative to seat. ^ 2 cl, 5 dwg |
