Q1: What is a safety valve?
1. The primary function of safety valves is to safeguard life, property, and the environment.
A safety valve is crafted to open and release overpressure from a container or device and to reseal and prevent further fluid release once normal conditions are restored.
2. A safety valve acts as a crucial safety device, often serving as the last line of defense.
It is essential that the safety valve remains functional at all times and under all scenarios.
Safety valves are distinct from process valves or pressure regulators and must not be misused.
Their sole function is to provide overpressure protection.
Q2: How does a safety valve work?
The operational principle of a safety valve is as follows:
1. Open: When system pressure surpasses the set threshold, the valve disc opens due to medium pressure and spring force, thereby releasing excess pressure.
2. Keep Open: As the system pressure stabilizes at the set level, the spring stabilizes, maintaining stress in the system and keeping the safety valve open.
3. Close: When system pressure falls below the set limit, the spring loses its ability to lock and seal, causing the valve disc to close under medium pressure, preventing any further pressure increase.
