Q1: What is a safety valve?
1. Safety valves are crucial for protecting life, property, and the environment. They are meticulously designed to open and release overpressure in a container or device, and to re-close and prevent further fluid release once normal conditions are restored.
2. As essential safety devices, safety valves often serve as the final line of defense. Ensuring their reliability and functionality under all circumstances is paramount. Remember, safety valves are neither process valves nor pressure regulators and should solely be used for overpressure protection.
Q2: How does a safety valve work?
The working principle of a safety valve can be summarized as follows:
1. Open: When system pressure surpasses the safety valve's set pressure, the valve disc is pushed open by the medium pressure and spring force, releasing the excess pressure.
2. Stay Open: As the system pressure stabilizes within the set range, the spring stabilizes the system under stress, keeping the safety valve open to maintain balance.
3. Close: Once the system pressure falls below the safety valve's set threshold, the spring loses its locking ability, causing the valve disc to close under the medium pressure, and halting any further increase in medium pressure.
