Define the term 'safety relief valve' in boiler systems.

A safety relief valve is a critical component in boiler systems that is specifically designed to open and release pressure when it reaches a predetermined limit. This function is essential for preventing boiler failure and ensuring the safety of the entire system. By automatically venting excess pressure, the safety relief valve helps avert potentially dangerous situations, such as explosions or ruptures that could occur if pressure continues to build unchecked within the boiler.

Understanding this function is crucial for anyone working with boiler systems. The safety relief valve is standardized for various pressure settings, ensuring that the boiler operates within safe limits. This proactive safety measure is an integral part of maintaining the boiler’s integrity and overall operational safety.
