Q1: What is a safety valve?
1. Safety valves are essential for protecting life, property, and the environment. They are designed to open and release excess pressure from a container or device and then re-close to prevent further fluid release once normal conditions are restored.
2. A safety valve serves as a critical safety device, often the last line of defense. It must be capable of operating reliably at all times under any circumstances. Safety valves are not designed to function as process valves or pressure regulators and should only 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 exceeds the valve's set pressure, the valve disc opens due to the combined force of the medium pressure and spring force, thereby relieving the pressure.
2. Keep open: Once the system pressure stabilizes within the set range, the spring stabilizes, allowing the valve to remain open while the system is still under stress.
3. Close: When the system pressure falls below the set pressure, the spring can no longer maintain the open state, causing the valve disc to close under the medium pressure, stopping any further increase in pressure.
