Definitions

  • 1 indicates an elastic fluid turbine of any suitable type, the turbine being provided with a fluid chest 2 to which elastic fluid is supplied by conduit 3.
  • conduit 3 is a combined trip and throttle valve 4, a well known type being indicated diagrammatically.
  • Valve4 is biased toward closed position but is held open normally by a catch controlled b a linkv 5 which is connected by a rod 6 to hell crank lever 7 Gonnected to the free end of bell crank lever 7 1927.
  • rod 34 is set in its in position as shown in Fig. 3 and the compression of spring 26 is adjusted by means of nut 27 for the desired emergency tripping speed.
  • the turbine is running and it is desired to test theemergency governing mechanism, it is necessary -mere 131 to move rod 34 to its out position by means of hand lever 37 thereby decreasing the compression of spring 26, whereupon the emergency governor will operate to effect tripping of the emergency valve mechanism.
  • the emergency governor is restored to its former condition by moving rod 34 back to its in position.
  • an emergency governor comprising an annular eccentrically mounted weight member which surrounds the shaft, a support which is independent of the weight member, a radially extending spring located between the weight member and the support which opposes movement of the weight member under the action of centrifugal force, and means for effecting movement of said support while the shaft is rotating for changing the setting of said spring whereby the emergency governor may be operated under the action of centrifugal force at a lower speed.
