Abstract

PURPOSE: To increase a driving force of a test pilot valve and prevent its malfunction by operating the test pilot valve in the opening direction by means of an especially provided cylinder or in the closing direction by means of an oil which is carried under a pressure into a pilot chamber in the valve.
CONSTITUTION: A turbine bypass valve (TBV) 1 is opened or closed under the control of a valve driving device which contains a control pilot valve 13, a hydraulic cylinder 4 for driving the valve, and a cam 14. During the operation of a turbine, the TBV is subjected to an opening or closing test by a test device which contains a test pilot valve 3 and a test cylinder 17 connected to said valve driving device. A hydraulic cylinder 40 is connected to one end of the test pilot valve 30 so as to controll a spool 32 of the valve 30 to open a feed port 36 for the test cylinder 17. At the other end of the valve 30, a pilot chamber 31 is provided into which an oil is carried under a pressure to make the spool 32 close the port 36. In addition, a compression spring 33 is contained in the chamber 31.
