Q1: What is a safety valve?
1. The primary purpose of safety valves is to safeguard life, property, and the environment. A safety valve is engineered to open and release excess pressure in a container or device, then reclose to prevent further fluid discharge once normal conditions are restored.
2. A safety valve serves as a critical safety device, often acting as the last line of defense. It is essential for the safety valve to be operational at all times and under all conditions. Unlike process valves or pressure regulators, safety valves should be exclusively utilized for 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 safety valve's set pressure, the valve disc opens under the combined forces of medium pressure and spring force, facilitating pressure release.
2. Keep Open: As system pressure stabilizes within the set parameters, the spring remains balanced, maintaining the system under controlled stress while keeping the safety valve open.
3. Close: When system pressure falls below the set pressure, the spring fails to lock and seal, causing the valve disc to close under medium pressure, thus halting any further pressure increase.
