Q1: What is a safety valve?
1. The primary function of a safety valve is to protect life, property, and the environment by preventing overpressure scenarios.
A safety valve is crafted to open and release excess pressure from a container or device, then re-close to halt further fluid release once normal conditions are restored, ensuring optimal safety.
2. Serving as a critical safety device, a safety valve often acts as the last line of defense in overpressure situations.
Ensuring the readiness and functionality of the safety valve under all circumstances is vital.
Safety valves are distinct from process valves or pressure regulators and must not be misused.
Their singular role is to provide overpressure protection.
Q2: How does a Safety Valve operate?
The operation of a safety valve can be detailed as follows:
1. Open: Upon system pressure exceeding the safety valve's set pressure, the valve disc opens due to the medium pressure and spring force, effectively releasing the excess pressure.
2. Keep Open: Once the system pressure stabilizes within the set range, the spring maintains its tension, keeping the safety valve open while the system remains under control.
3. Close: When system pressure falls below the safety valve's set pressure, the spring fails to lock and seal, causing the valve disc to close under medium pressure, halting any further pressure increase.
