Who can explain in a systematic way this single-stage steam small turbine, and how is its steam intake regulated?

There is also its structure and the functions of its various components
The one circled in the first diagram is the overspeed trip valve; the one circled in the fourth diagram is the governor system
Does the governor use the centrifugal principle of a flying weight to control the steam flow?
Does the governor use the centrifugal principle of a flying weight to control the steam flow?
The movement of the flying hammer changes the position of the guide vanes, which in turn alters the oil pressure acting on the power piston. This causes the shaft of the rod connected to the speed control valve to move, changing the opening degree of the speed control valve and thus regulating the steam flow to achieve automatic speed control.
The fly hammer centrifugal principle is a method for mechanical shutdown and emergency stop
The movement of the flying hammer changes the position of the guide spool, thereby altering the oil pressure acting on the power piston.

Yes, the governor uses the centrifugal principle of a flying weight to control the steam flow rate!
Hello, from the several pictures I sent, it doesn’t seem as complicated as you said. Are you referring to its use in large steam turbines? It seems that in the pictures I sent, it comes out of the bearing housing
It’s not possible to tell from the diagram where the power oil pressure is, or rather, no external oil pressure pipelines can be seen
