Q1: What is a safety valve?
1. The primary purpose of safety valves is to protect life, property, and the environment. A safety valve is designed to open and release excess pressure from a container or device and reclose to prevent further release when normal conditions are restored.
2. Safety valves serve as the ultimate safety device, often being the last line of defense. It is crucial that safety valves function correctly at all times and under any circumstances. They are not intended to be process valves or pressure regulators and must be used solely for overpressure protection.
Q2: How does a safety valve work?
The working principle of a safety valve is as follows:
1. Open: When the system pressure exceeds the valve's set pressure, the valve disc opens due to medium pressure and spring force, thereby releasing pressure.
2. Remain open: Upon stabilizing the system pressure within the set limits, the spring stabilizes, keeping the safety valve open while maintaining system stress.
3. Close: When system pressure falls below the set pressure, the spring cannot lock and seal, causing the valve disc to close under medium pressure, preventing further pressure increase.
