Abstract:
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.

Claim (Index 1):
A steam valve, comprising:\n a valve casing having a valve chest, an inlet flow passage having an opening into the valve chest, an outlet flow passage having an opening into the valve chest, and a valve seat surrounding the opening of the outlet flow passage; a first valve body housed in the valve chest and capable of making contact with the valve seat in a vertical direction; a second valve body housed in the valve chest coaxially with the first valve body and capable of making contact with the valve seat in the vertical direction; a second valve rod inserted through an upper section of the valve casing in the vertical direction and extending from the second valve body to an outside of the valve casing; a first valve rod inserted through an inside of the second valve rod and extending from the second valve body to the outside of the valve casing; a first actuator disposed outside the valve casing and capable of applying a first biasing force in the vertical direction to the first valve rod; a second actuator disposed outside the valve casing and 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 when the linking part moves in the vertical direction in response to tilting of the lever.
