Q1: What is a safety valve?
1. Safety valves are crucial for safeguarding life, property, and the environment.
A safety valve is meticulously designed to automatically open and release overpressure from a container or device. Once normal conditions resume, it efficiently reseals to prevent further leakage.
2. It serves as a critical safety device, often being the last line of defense.
Ensuring a safety valve's reliable operation in all conditions is paramount.
Remember, safety valves are not meant to function as process valves or pressure regulators and should be used solely for overpressure protection.
Their singular purpose is to provide overpressure protection.
Q2: How does a Safety Valve work?
The operation of a safety valve can be broken down into three stages:
1. Opening: When system pressure surpasses the valve’s set point, the valve disc opens due to the medium pressure and spring force, relieving the excess pressure.
2. Staying Open: As the system pressure stabilizes within the set parameters, the spring maintains its position, keeping the valve open to manage the system stress.
3. Closing: Once the system pressure falls below the set threshold, the spring regains its locking capability, and the valve disc closes, preventing any further pressure build-up.
