Q1: What is the safety valve?
1. The primary function of safety valves is to safeguard life, property, and the environment.
A safety valve is specifically designed to open and relieve overpressure in a container or device, then re-close and prevent further fluid release once normal conditions are restored.
2. As a crucial safety device, a safety valve often serves as the ultimate line of defense.
Ensuring the safety valve operates reliably under all conditions is vital.
Safety valves are not substitutes for process valves or pressure regulators and should be used solely for overpressure protection.
Their exclusive function is to provide overpressure protection.
Q2: How does a Safety Valve work?
The operating principles of a safety valve are as follows:
1. Open: When system pressure exceeds the predefined limit, the valve disc opens due to the medium pressure and spring force, thereby releasing excess pressure.
2. Keep open: As the system pressure stabilizes within the set range, the spring maintains its position, keeping the system pressurized and the valve open.
3. Close: When the system pressure falls below the set limit, the spring's inability to lock and seal causes the valve disc to close under medium pressure, halting any further pressure increase.
