Question

A relief valve containing a thin metal disc that bursts before the pressure in a system reaches dangerous levels is commonly known as a:

A) Pressure relief valve
B) Check valve
C) Solenoid valve
D) Rupture disc

Answer 1

A rupture disc is a type of safety device designed to burst at a predetermined pressure to prevent a system from reaching dangerous levels, unlike other valves that might reseal or control fluid direction or flow.

Step-by-step explanation:

The valve in question is commonly known as a rupture disc. A rupture disc is a safety device that is designed to prevent the pressure in a system from reaching dangerous levels. It is composed of a thin metal disc that is intentionally engineered to burst or rupture at a predetermined pressure, thereby releasing the excess pressure safely and averting any potential hazards. This device is different from other types of valves as it's a one-time-use component that needs to be replaced after it has functioned.

It differs from a pressure relief valve, which may reseal after relief, a check valve, which prevents fluid from flowing in the reverse direction, and a solenoid valve, which is an electromechanically operated valve controlling the flow of fluid. The correct answer to the question is D) Rupture disc.
