Question

Quizplus · Accepted Answer

Fusible-plug pressure-relief valves operate on the principle that as the pressure in a tank increases,the temperature of the gas increases,causing the plug to melt.Spring-loaded devices are designed to release excessive cylinder pressure and reseal,preventing further release of gas from the cylinder after the cause of the excessive pressure is removed.The rupture-disk will buckle when the pressure inside the cylinder exceeds a certain predetermined limit.Direct-acting valves are not pressure-relief valves; instead,they are controlling devices that seal the contents of a compressed cylinder until it is ready for use.
