The invention discloses a power turbine regulation assembly for a propeller governor. A supporting rod shifting fork assembly comprises a balancing weight, a spring I, a spring II, a shifting fork, asmall wheel and a supporting rod. The balancing weight is fixed at one end of the shifting fork, a U-shaped fork is arranged at the other end of the shifting fork, and the shifting fork is hinged to the supporting rod; the small wheel is arranged in a U-shaped groove of the shifting fork, and a pin assembled in an inner hole of the small wheel in a clearance mode is fixed to a U-shaped end wall; anozzle is fixed in a mounting hole extending out of the side wall of the lower end of the governor shell; a baffle support assembly comprises a baffle and a spring III fixed to the side wall of the baffle, one side wall of the baffle seals the nozzle in a normal state, and the small wheel abuts against the side wall of the other end of the baffle; and a U-shaped groove in the lower end of the supporting rod 11 is inserted into a reset handle assembly. When a valve element bonnet ascends or the reset handle assembly acts, the balancing weight presses the baffle of the baffle support assembly downwards, and the nozzle is opened to spray air. The propeller overspeed protection function is achieved, and the auxiliary functions of beta control and propeller reversing are achieved.
