Automatic shaft seal operation adjusting device for waste heat power generation turboset

The utility model discloses an automatic shaft seal operation adjusting device of a waste heat power generation turboset, which comprises a shaft seal, a turbine, a shaft seal cooler, a steam collecting box, a distribution valve and a condenser, and the steam collecting box is provided with an outer net steam inlet, a front shaft seal steam inlet and a rear shaft seal steam supply port. One path of pressure is led from the steam collecting box to the upper end of the distribution valve to serve as a pressure signal for automatic adjustment, when the pressure of the shaft seal is larger than the set pressure, the distribution valve works, steam of the steam collecting box is led to the condenser, and the steam supply pressure of the shaft seal is stable, the distribution valve stops acting, and when the pressure of the shaft seal is smaller than the set pressure, the distribution valve works to reduce the amount of the steam of the steam collecting box to the condenser. And after the steam supply pressure of t
