What is a "safety valve" and how does it function?

A safety valve is a crucial component in various pressure-containing equipment, including boilers. Its primary function is to prevent dangerous pressure levels from building up within a system. When pressure rises above a predetermined limit, the safety valve opens automatically to release excess pressure, thereby safeguarding the equipment and preventing potential failures or explosions.

This mechanism is vital in maintaining the safe and efficient operation of boilers. By allowing steam or gas to escape in a controlled manner, it helps to stabilize pressure levels and ensures that the system operates within its safe operating limits. Understanding this function is essential for anyone working with boilers, as effective pressure management is key to safe operations.
