Q1: What is a safety valve?
1. Safety valves are crucial for safeguarding life, property, and the environment. They are designed to automatically open and release excess pressure from a container or system and then re-close to prevent further fluid release once normal conditions are restored.
2. Safety valves act as critical protection devices, often serving as the last line of defense. It is essential to ensure they can function reliably under all conditions. Unlike process valves or pressure regulators, safety valves are solely for overpressure protection and should not be misused.
Q2: How does a safety valve work?
The working principle of a safety valve can be described as follows:
1. Open: When system pressure surpasses the set threshold, the valve disc opens due to medium pressure and spring force, allowing excess pressure to escape.
2. Keep open: As the system pressure stabilizes to the set level, the spring maintains balance, keeping the safety valve open under ongoing stress.
3. Close: When system pressure drops below the set level, the spring force is unable to lock and seal the valve, leading the valve disc to close under medium pressure, preventing further pressure increase.
