Pressure Relief Devices: Which One Works by Temperature?

What pressure relief device works primarily by temperature?

A) Fusible plug
B) Rupture disc
C) Safety valve
D) Pressure relief valve

Answer:

The pressure relief device that primarily works by temperature is the Fusible plug.

Pressure relief devices are crucial components in systems to prevent dangerous build-up of pressure. Among the options given, the Fusible plug stands out as the pressure relief device that primarily works by temperature.

A fusible plug is designed to melt at a specific temperature, usually when this temperature exceeds safety limits. This unique mechanism allows fluid or gas to escape from the system, relieving the pressure that could potentially cause damage or hazards.

Unlike the other options provided (rupture disc, safety valve, pressure relief valve) that respond to overpressure conditions, the fusible plug's primary trigger is the excess temperature. This characteristic makes it a valuable safety feature in various industrial and mechanical systems.

Understanding the function of pressure relief devices, especially the fusible plug, is essential in ensuring the safety and optimal performance of systems. By recognizing how each device operates, maintenance and troubleshooting can be conducted effectively to prevent accidents and enhance overall system efficiency.
