摘要： PURPOSE:To test cut-off and control valves disposed in a low-pressure turbine bypass line without generating heat loss during a normal opertion by installing a control circuit which prevents simultaneous opening of both valves. CONSTITUTION:In a valve test, a switch 49 is turned on to energized relays 50, 51. the relay 51 actuates a servo-valve 40 to have an operation cylinder 39 fully open a valve body 46 of a control valve 7. Detecting the fully opened valve body 46, a limit switch 42 deactuates a relay 52 and releases the self-holding state of a relay 51 so that the servo-valve 40 operates to fully close the valve body 46. On the other hand, when said switch 42 is on it energizes a relay 54 to operate a relay 55 for testing a following cut-off valve. When the control valve 7 is closed to open the limit switch 43, the relay 53 is deenergized. With a relay 55 is on, a cut-off valve 6 may be tested.

摘要： PURPOSE:To carry out the switch test without giving any effect to the operation of the atomic power turbine plant, by providing the air-actuating valve to the drain detecting piping of the hygroscopic moisture separator in order to form the test water supply system to the level switch main body. CONSTITUTION:The moisture in the vapor for driving the atomic power turbine is separated by hygroscopic moisture separator 1 and then applied to level switch main body 14 via drain detecting pipings 26a and 26b which interlock main body 14 which stores separator 1 and float 15. And the supply of vapor to the turbine is controlled by water level upper and lower limit position detecting limit switches 11 and 12 interlocking float 15. The test water supply system comprising water supply tank 16 including air-actuating valves 6 and 8 is connected to pipe 26a. Thus the level switch test is possible whithout giving any effect to the plant operation and according to the operation of valves 6 and 8. The used water after the test is treated by the drain system provided to pipe 26b.

摘要： PURPOSE:To make it possible to make sure of the operation of a level switch even in plant operation by moving vertically a float regardless of the water level of moisture stored in a moisture separator and by excluding electric signals for assigning the stop of an inflow of a fluid and its release. CONSTITUTION:Compressed air 1 is supplied by exciting solenoid valve 2 to push up piston 15 of air cylinder 4, and then float 9 is pushed up via link mechanism 10 to operate water-level upper-limit switch 5, thereby testing the operation of switch 5. Since a circuit that stops a turbine at the water-level upper-limit position is turned off with a signal exciting solenoid valve 2, a turbine plant continues its normal operation. With switch 5 in operation, solenoid valve 2 is unexcited to exhaust air in air cylinder 4 and float 9 returns to its original position. Then, the operation of water-level upper-limit-position limit switch 6 is tested and then exclusion of the turbine stop signal is released to set the original state.

摘要： PURPOSE: To maintain turbine output always stably by adjusting temperature of oil supplied to bearings to a desired temperature with operative medium liquid for a turbine.
CONSTITUTION: An apparatus for adjusting temperature of lubricating oil for bearings is constituted from an oil cooler 21, a cooling water circuit provided between a Rankine cycle water supply piping 6 and the oil cooler 21, a bypass 27 provided between a lubricating oil cycle oil supply piping 8 and the oil cooler 21 and having an adjusting valve 28 for lubricating oil flow and an opening control section of a flow adjusting valve 28. The opening control section of the flow adjusting valve 28 detects temperature of supplied oil mixture of lubricating oil cooled in the oil cooler 21 and lubricating oil passed through the by-pass 27 without being cooled, by a temperature detecting element 29 to convert the output signal to air signal 31 which adjusts the opening of the flow adjusting valve 28. Thus, since an amount of operative medium liquid flowing in a heat exchanger 1 is maintained constant, vapor of the operative medium is held at a certain flow and the output of a turbine is always maintained constant.
