🔍 Key Concepts

• Guardian valves location in a main propulsion steam turbine system • Relationship between guardian valves, throttle valves, and astern elements • How steam leakage into the astern element would affect turbine operation at different speeds

💭 Think About

• Think about when it is most critical to prevent steam from unintentionally entering the astern element of a turbine. • Consider whether a guardian valve’s primary job is emergency shutdown, control of direction, or protection from leakage. • Ask yourself: Is the guardian valve used actively by the operator during maneuvers, or is it more of a protective safety feature in normal full-power operation?

✅ Before You Answer

• Identify whether the throttle valve or the guardian valve is intended for quick emergency closure of steam flow. • Determine at what operating condition (full sea speed vs. maneuvering) unwanted steam in the astern element would be most dangerous to the turbine. • Confirm whether the guardian valve’s main function is to supply steam to the astern element or to isolate/protect it from unintended steam flow.
