Steam admission adjustment valve connection rod mechanism of steam turbine

The utility model relates to a steam admission adjustment valve connection rod mechanism of a steam turbine. The steam admission adjustment valve connection rod mechanism is structurally characterized in that the two ends of a rotary shaft are fixed to a base plate through a supporting frame and can rotate; one end of a connection rod IV is fixed to the base plate through the supporting frame and can rotate; one end of a connection rod I, one end of a connection rod II and one end of a connection rod III are respectively fixed to the rotary shaft, the other end of the connection rod I is connected with an oil cylinder piston rod of a bi-directional hydraulic oil cylinder through a guide connector, the oil cylinder piston rod penetrates through the base plate, the other end of the connection rod II is connected with a low-pressure adjustment valve connection rod through a guide connector, the low-pressure adjustment valve connection rod penetrates through the base plate and is connected with a low-pressure adjustment valve, the original position of the connection rod III is h meters away from the connection rod IV, the connection rod III makes contact with the connection rod IV after rotating and drives the connection rod IV to rotate around a connection point, and the two ends of a spring are fixed to the base plate and a spring pallet; one end of a connection rod V is fixed to the connection rod IV, and the other end of the connection rod V penetrates through the spring and is connected with the spring pallet; one end of a high-pressure adjustment valve connection rod is fixed to the spring pallet, and the other end of the high-pressure adjustment valve connection rod is connected with a high-pressure adjustment valve. The steam admission adjustment valve connection rod mechanism is safe, reliable and convenient to install and adjust.
