Abstract

PURPOSE: To enable to control open-and-shut of an intercept valve also with revolution of the secondary shaft by providing the secondary turbine side with a duplex spindle-type rotary pilot valve working according to its revolution.
CONSTITUTION: In the case of a two-axle steam turbine pararell arranged with the primary turbine 1 having high-and-medium pressure turbines 1a, 1b and the secondary turbine having a low pressure turbine (illustration omitted), the secondary turbine is provided with a centrifugal duplex spindle-type rotary pilot valve 21, which is driven through a worm 20b and a wheel 20c from a secondary shaft 20a. And an exit port 21 of said valve 21 and an oil feeding port 19c of a pilot valve 19a of an intercept valve control device 19 are connected through an oil pressure line 24. And also a pressure switch 24a detecting oil pressure drop of the oil pressure line 24 and a ventilator valve 26, which is opened through a relay 25 by working of said pressure switch, are provided.
