🔍 Key Concepts

• Inverted bucket steam trap operation – how steam vs. condensate affects the bucket’s buoyancy • Relationship between bucket movement (rising or sinking) and the position of the discharge valve • Whether condensate discharge is intermittent vs. continuous in this type of trap

💭 Think About

• When steam enters under the bucket, does it make the bucket rise or sink, and what does that do to the valve? • As the steam condenses and the bucket changes position, at which point is the outlet passage opened to let condensate out? • Does an inverted bucket trap maintain a constant liquid level, or does the level cycle up and down as the trap works?

✅ Before You Answer

• Identify which part in the illustration is the bucket and which is the valve/seat linkage • Decide whether the discharge from an inverted bucket trap is cyclic (on/off) or smooth and continuous • Match the bucket motion (rising vs sinking) with opening or closing of the outlet valve based on the linkage shown
