Title: Valve-actuating arrangement
IPC: F01D21/20
Filed: 1967-12-27
Abstract: 1,203,970. Fluid-pressure servomotor systems. TOKYO SHIBAURA DENKI K.K. Dec.27, 1967. [March 31, 1967], No.58747/67. Heading G3P. [Also in Division F1] The steam supply to the four nozzle sections of a turbine is controlled in response to turbine load by respective valves 8 (only one of which is shown) each of which is controlled by a respective out of cams 2-5 via linkage 9, 13, 14, spool valve 15, servomotor 16 and linkage 18, 19. To allow manual testing of each valve 8 to a partially closed position, each floating lever 14 is connected to its spool 15 via an extensible link 14a Fig.2 comprising a piston 28 fast with the spool and a cylinder 25 fast with lever 14. Spring 27 ensures that the piston and cylinder normally move together. However, upon energizing a valve 31, fluid is admitted to depress spool 29a to admit fluid to the cylinder to move the piston against the spring to actuate spool 15 and thereby partially close valve 8. Failure of the piston 28 to return to the position shown after test is detected by an alarm actuated by switch 32. In a modification spool 29a is positioned by a solenoid energized by an adder comparing a demand signal with a signal from a differential transformer sensing the position of piston 28.
