What is the potential consequence of a relief valve malfunctioning due to a broken spring?

The potential consequence of a relief valve malfunctioning due to a broken spring is excessive system pressure. Relief valves are designed to maintain safe pressure levels within a system by releasing excess pressure when it reaches a predetermined limit. The spring in the relief valve applies the necessary force to keep the valve closed until the system pressure exceeds this limit. If the spring is broken, the valve may fail to open at the correct pressure, allowing the pressure in the system to continue to rise unchecked.

This scenario can lead to overpressure conditions, which pose significant risks, including damage to equipment, piping, and other components, as well as potential safety hazards. It disrupts the intended function of the relief valve, which is crucial for preventing catastrophic failures and ensuring system safety. Understanding the role of the spring in a relief valve helps illuminate why a malfunction can have such serious implications for system pressure management.
