Q1: What is a safety valve?
1. Safety valves are crucial for protecting life, property, and the environment. These valves are engineered to open and release excess pressure from a container or device and to re-close, preventing additional fluid release once normal conditions are restored.
2. A safety valve is often the last line of defense, essential for operational safety under all conditions. Unlike process valves or pressure regulators, safety valves are not to be misused. Their sole function is overpressure protection.
Q2: How does a safety valve work?
The operational principle of a safety valve can be summarized as follows:
1. Opening: When the system pressure surpasses the valve's set pressure, the valve disc is pushed open by the medium pressure and spring force, allowing pressure release.
2. Maintain Open: As long as the system pressure remains within the set threshold, the spring remains stabilized, keeping the safety valve open and the system under controlled pressure.
3. Closing: When the system pressure drops below the set pressure, the spring action can no longer maintain the open position. The valve disc closes, halting further pressure increase.
