What is considered a "safety valve" in a boiler system?

A safety valve in a boiler system is a critical component designed to automatically release steam to prevent excessive pressure from building up within the boiler. When the internal pressure exceeds a predetermined limit, the safety valve opens to allow steam to escape, thereby maintaining safe operating conditions. This mechanism is essential for preventing potential hazards such as boiler explosions or failures, ensuring that the system remains within safe operational parameters.

The safety valve is engineered to react quickly to changes in pressure, functioning as a fail-safe to protect both the equipment and personnel. Maintaining appropriate pressure levels is crucial for the efficient and safe operation of the boiler, making the safety valve a vital aspect of the overall safety infrastructure in boiler systems.
