Q

The operation of a bellows type thermostatic steam trap depends upon the __________.

🔍 Key Concepts

• Principle of operation of a bellows-type thermostatic steam trap • Difference between float, thermostatic (bellows), and thermodynamic steam traps • How temperature changes are used to open or close a valve in steam traps

💭 Think About

• Which option describes something that reacts directly to temperature changes of condensate and steam, rather than liquid level or pressure drop alone? • Look for the choice that specifically involves a sealed element whose volume changes with temperature, causing a valve to move. • Ask yourself: which options clearly describe other known trap types (like float traps or thermodynamic traps) rather than a bellows-type thermostatic trap?

✅ Before You Answer

• Identify which option mentions a sealed chamber or element that responds to temperature, not level. • Eliminate any option that relies mainly on liquid level (float action) instead of temperature. • Eliminate any option that describes pressure drop / flashing action typical of thermodynamic traps, not bellows-type traps.
