FIELD: heat-power engineering; systems for protection of extraction turbines against rise of pressure in the bleeding-off chamber. SUBSTANCE: steam bleeding-off pipe line is provided with safety valves. One safety valve is mechanically linked with hydraulic switch by means of leverage. Hydraulic switch is used to control servomotor. Lever of hydraulic switch is mounted for free motion relative to mechanical rod; levers of safety valve and hydraulic switch are mounted in such position that relationship of lever arms changes according to change of rearranging force exerted on the valve when safety valve operates and valve cup rises in the course of motion of leverage. EFFECT: enhanced efficiency. 3 dwg
