A steam valve includes: a valve casing; a first valve body; a second valve body; a second valve rod; a first valve rod; a first actuator capable of applying a first biasing force in the vertical direction to the first valve rod; a second actuator capable of applying a second biasing force in the vertical direction to the second valve rod; a first link mechanism disposed between the first actuator and the first valve rod and capable of transmitting the first biasing force; a second link mechanism disposed between the second actuator and the second valve rod and capable of transmitting the second biasing force, the second link mechanism having a linking part provided integrally with the second valve rod and a lever which is pin-coupled to the linking part; and a guide mechanism capable of regulating horizontal displacement of the linking part.

Steam valve and steam turbine system

A steam valve includes a valve casing, a first valve body having a first cylindrical part and a first end wall part, a second valve body having a second cylindrical part and a second end wall part, a first valve stem capable of vertically biasing the first valve body, a second valve stem capable of vertically biasing the second valve body, a flow guide disposed inside the first cylindrical part and having a projection configured to project downwardly from the first cylindrical part and the second cylindrical part when the first cylindrical part and the second cylindrical part are apart from the valve seat, and a support supporting the flow guide. The support extends from the valve casing or the second valve body to the flow guide through a through hole formed in the first valve body to support the flow guide such that the flow guide is tiltable.

A method of testing a receptor of a wind turbine includes a step of moving an unmanned aerial vehicle (UAV) close to the receptor of a wind turbine blade mounted to a hub of the wind turbine, and performing an electric continuity test on the receptor.
