Abstract

PURPOSE: To prevent overspeed of turbine, by providing a control valve and a bypass valve in a bypass pipe which is extended from a portion of the turbine to the exhaust pipe of turbine.
CONSTITUTION: A high-pressure bypass pipe 14 is provided for communicating a capacity section 11 formed between high-pressure control valve 2 and high-pressure turbine 3 to exhaust pipe 3 of low-pressure turbine 7, and a high-pressure bypass valve 15 is provided in the bypass pipe 14. Similarly, there is provided a low-pressure bypass valve 17 in the same way. With such an arrangement, when load is removed, control circuit 19 is set into operation for opening both of the bypass valves 15, 17 rapidly, so that working fluid remaining in capacity sections 11, 12 is dumped into exhaust pipe 13 instead of flowing into high-pressure turbine 3 and low-pressure turbine 7. Therefore, output of these turbines 3, 7 is lowered and they can be protected against overspeed.
