Don’t understand the relationship between the main steam valve and the throttle valve?
Thread Content
Issues related to turbines: Do the following two sets of terms, main steam valve and main steam gate, refer to the same concept? Are the speed control valve and the regulating valve the same concept? I’m a bit confused. Please help to explain it.
It is a concept; the main steam valve, also known as a quick-shut valve, is used for self-protection shutdown. Throttle valves and speed control valves are used to regulate the speed of turbines
The main steam valve and the main steam gate refer to the same concept, and the throttle valve and the control valve also refer to the same concept. Doors and valves are the same thing; both refer to valves. The main steam valve and main throttle, as well as the speed control valve and regulating valve, are the *common terms used on site. Steam is generated in the boiler and, via the main steam pipeline, passes through the main steam valve before reaching the turbine through the throttle valve. The main steam valve includes electric main steam valves and automatic main steam valves; the electric main steam valves also have bypass valves. Steam enters the turbine, first passing through the electric main steam valve, then the automatic main steam valve, and finally the throttle valve. Once the safety device activates, the automatic main steam valve closes immediately, cutting off the steam supply to the turbine and causing it to stop; therefore, the automatic main steam valve is also known as a quick-close valve. The electric main steam valve bypass valve is used during startup.
