Q1: What is a safety valve?
1. The primary role of safety valves is to safeguard life, property, and the environment. Designed to open and release overpressure in vessels or devices, safety valves re-close to prevent further fluid release once conditions normalize.
2. As a crucial safety device, safety valves often serve as the final defense against overpressure. They must be dependable under all conditions, distinct from process valves or pressure regulators, and should only be used for overpressure protection.
Q2: How does a Safety Valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When system pressure exceeds the safety valve's set point, the valve disc opens due to the medium's pressure and spring force, releasing the excess pressure.
2. Keep open: The valve remains open as long as the system pressure stabilizes within the set range, ensuring consistent pressure maintenance.
3. Close: Once the system pressure falls below the set point, the spring pressure reseals the valve disc, halting further pressure increase.
