Safety Valve Commissioning Procedure
Comprehensive Guidelines for Proper Installation and Testing
1. Thorough Preparation Before Commissioning
- Clean the safety valve surface of any oil or impurities and ensure that the valve body components are free of blockage or damage.
- Check the connecting pipes for unobstructed flow and any loose connections to prevent fuel leaks during commissioning.
- Ensure the commissioning environment is well ventilated and away from sources of fire and static electricity.
- Prepare appropriate protective equipment to ensure safe operation.
2. Follow Standard Procedures When Setting Pressure
- Slowly adjust the safety valve's adjusting screw and observe the pressure indicator to ensure the opening pressure meets the equipment's design specifications.
- Maintain smooth operation during commissioning to avoid sudden pressure increases or decreases caused by vigorous operation.
- If abnormal pressure fluctuations are detected, pause adjustment and inspect the valve body for any obstructions.
- Resolve any problems before continuing.
3. Focus on Sealing Performance Inspection
- When operating below the set pressure, inspect the safety valve sealing surface for leaks.
- Apply soapy water to detect minor leaks.
- If a poor seal is detected, carefully inspect the gasket and replace it if necessary.
- Ensure the safety valve is completely sealed under normal operating pressure to prevent fuel loss or safety hazards caused by minor leaks.
4. Perform a Linkage Test After Basic Commissioning
- Simulate an abnormal increase in fuel tank pressure to observe whether the safety valve opens and releases pressure promptly at the set pressure.
- Verify that the valve automatically closes after the pressure drops.
- Repeat the test multiple times to ensure the valve opens and closes smoothly and reliably, without any sticking or delay.
- After the test, record the commissioning results and secure the adjustment components to prevent the pressure setting from drifting during operation.
