🔍 Key Concepts

• Boiler safety valve construction – how the blowdown ring is adjusted and then secured so it cannot move during normal operation • Difference between adjusting devices (used to set pressure/blowdown) and sealing or locking devices (used to prevent tampering) • Typical small‑machinery hardware: what is normally used to lock a ring in a threaded position against vibration

💭 Think About

• Think about which item would positively keep a threaded ring from rotating once it is set, even under vibration and heat cycling • Ask yourself which choice is commonly used to lock an adjustable ring on a shaft or body, rather than just to indicate that it has been inspected or assembled • Consider what a surveyor or inspector would expect to find if they wanted to be sure the blowdown setting hadn’t been changed without authorization

✅ Before You Answer

• Which option actually prevents rotation of the ring by mechanically engaging it, not just tagging or indicating position? • Which device is commonly used in machinery as a locking device for an adjustment on a threaded part? • Eliminate any choices that are mainly used only as a tamper‑evident seal or for safety pinning that does not allow fine adjustment.
