Abstract

PURPOSE: To restrain the erosion of a valve, by means of reducing the using time of the secondary valve by closing the secondary valve when in a large flow quantity.
CONSTITUTION: The rotation number of an expander 1 is kept at a constant by means of causing a small regulating valve 13 to be actuated by control signal from a regulator 3 by forming a signal system line as shown in (a) of a change-over device 4. The inflowed gas into the expander 1 becomes to a regulable quantity only by a regulating valve 11 as the share of power generation due to the generator synchronized with outer source and of a machine to be driven, shall be enlarged. At this time, it becomes to a system line as shown in (b) by means of being changed over by a signal from a change-over signal transmitter 5, and the small regulating valve 13 is closed. The regulating valve 11 takes over the quantity that was let flow by the small regulating valve 13. By such means, the erosion of the master and the second valves can be restrained, by means of using valves suitable in property properly according as the flow quantity, in a case of handling a erosive fluid.
