Abstract

PURPOSE: To compact the whole body, by specifying relationship among a valve body, a disc, an air cyliner and an oil damper.
CONSTITUTION: A main steam separating valve is formed by a valve body 1, a disc 3 mounted into valve body 1 in a sliding-free shape and an air cylinder 30 and an oil damper 40 connected to the disc 3 through a stem 7. The valve is opened and closed by injecting and exhausting compressed air to and from the air cylinder 30 by means of an injection and exhaust port. In this case, impact in case of the opening and closing of the valve is absorbed by the action of the oil damper 40. The valve is disassembled by disconnecting connection between a bonnet 2 and a spring case 50 and between a spring bearing 20 and the stem 7. The display of the opening and closing of the valve can be attained by installing a window to the spring case 50 and by detecting the motion of the spring bearing 20 by means of a limit switch.
