Q1: What is a safety valve?
1. Safety valves serve a critical role in safeguarding life, property, and the environment. Designed to open and release overpressure in a container or device, they reclose to prevent further fluid release once normal conditions are restored.
2. As the last line of defense, safety valves are essential safety devices. They must be reliable at all times and under all conditions. It's important to note that safety valves are not 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 pressure, the valve disc opens due to medium pressure and spring force, releasing the excess pressure.
2. Keep open: Once the system pressure stabilizes within the set range, the spring adjusts to maintain this equilibrium, keeping the safety valve open under consistent stress.
3. Close: As soon as the system pressure drops below the set pressure, the spring can no longer lock and seal, causing the valve disc to close under medium pressure, halting any further increase in pressure.
