Work as Psx=Ps02, i.e. pressure value P of the unit during bring into operation to stable state, in flash evaporation 9sxWith it is pre-
If initial pressure value Ps02When equal, adjustment sheet 12 is rotated to an optimal aperture, at this time locks adjustment sheet 12.
It closes first switch valve 42 and the 4th switch valve 72, second switch valve 52 and third switch valve 62 is constantly in closing
State.Stop being passed through gaseous coolant to the first adjusting pipeline 2 and the second adjusting pipeline 3, prevents adjustment sheet 12 from continuing to revolve because of differential pressure
Turn.
3) compressor emergency shutdown resets: when unit needs to shut down, second switch valve 52 and third switch valve 62 being opened, first
Switch valve 42 and the 4th switch valve 72 are closed；It takes gaseous coolant to be passed through the first adjusting pipeline 2 from flash evaporation 9, takes gas from condenser 8
State refrigerant is passed through the second adjusting pipeline 3；Release the locking of adjustment sheet 12 simultaneously, gaseous coolant sets up pressure difference, adjustment sheet 12 because
Thrust starts to rotate with central axis 13, and aperture starts to change for 0 ° from optimal aperture to minimum aperture, until aperture is reduced to minimum
After 0 ° of aperture, then locked with by adjustment sheet 12.Close second switch valve 52 and third switch valve 62, first switch valve 42 and the 4th
Switch valve 72 is constantly in closed state, stops being passed through gaseous coolant to the first adjusting pipeline 2 and the second adjusting pipeline 3, stop
To compressor tonifying Qi.
