A Practical Guide To Extending The Life Of Fluorine-lined Ball Valves
In industrial production, Lined Ball Valve is an important fluid control equipment, and its stability and durability are directly related to the smoothness and safety of the production line. However, the life of the fluorine-lined ball valve is not static, it is affected by many factors. Today, let's take a deep look at what factors affect the life of the fluorine-lined ball valve, and share some practical operation and maintenance suggestions to help you better extend its service life.
1. Follow standard operations to ensure stable operation
First of all, strictly using the fluorine-lined ball valve in accordance with the pressure, temperature and applicable medium range specified in the product manual is the basis for extending its life. Using it beyond these ranges may not only damage the valve, but also cause safety accidents. Therefore, be sure to carefully check the relevant parameters before selecting and using it.
2. Pay attention to temperature changes and reduce pipeline stress
Temperature change is another important factor that affects the life of the fluorine-lined ball valve. When the temperature changes too much, the pipeline will generate stress, which may cause damage to the valve. Therefore, during use, try to avoid excessive pipeline stress caused by temperature changes in the fluorine-lined ball valve. This effect can be reduced by installing expansion joints or taking other buffering measures.
3. Correct opening and closing methods to protect valve structure
It is forbidden to use non-formal tools such as levers to open and close the fluorine-lined ball valve. This is the key to protecting the valve structure from damage. Tools such as levers may cause improper valve operation, which may cause problems such as damage to the sealing surface or bending of the valve stem. The correct way is to use the matching handle or handwheel for smooth and slow operation.
4. Timely treatment of leakage and maintenance of sealing performance
Once leakage is found at the middle flange, measures should be taken in time to deal with it. If it is a slight leakage, you can try to evenly tighten the middle flange nut to eliminate it; if the leakage is serious or the middle flange sealing surface is damaged, you need to replace the sealing surface or add a middle flange gasket to repair it. Keeping the sealing surface in good condition is the key to ensure the long-term stable operation of the fluorine-lined ball valve.
5. Pay attention to the characteristics of the medium and prevent unstable factors
For some situations where the medium is unstable and easy to decompose, measures should be taken in advance to eliminate or limit the factors that cause the medium to decompose. Because unstable media may corrode valve materials, damage the sealing structure or cause leakage and other problems. These problems can be effectively prevented by adjusting the medium composition, controlling the reaction conditions or taking other protective measures.
6. Regular maintenance inspection and replacement of worn parts
High-speed media and solid particles in the media may damage the sealing surface of the fluorine-lined ball valve. Therefore, the wear of the sealing surface should be checked regularly during use. Once the sealing surface is found to be damaged prematurely or leaking, the seal should be replaced in time. In addition, attention should be paid to the wear of other vulnerable parts, such as valve stems, bearings, etc., and they should be replaced or repaired as needed.
7. Reduce the impact of vibration and protect the valve structure
Long-term and severe vibration of the pipeline will damage the structure of the fluorine-lined ball valve. In order to reduce this effect, shock absorbers can be installed on the pipeline or other vibration reduction measures can be taken. At the same time, vibration factors should also be considered when designing and installing valves, and suitable valve models and installation methods should be selected to reduce the impact of vibration on the valve.
8. Pay attention to environmental factors and prevent external risks
For pipeline systems with self-ignitable media, special attention should be paid to preventing potential risks such as direct sunlight or external fires. Risks can be reduced by installing sunshades, setting up fire isolation belts, or taking other fire prevention measures. In addition, regular inspections should be conducted to ensure that the fire prevention facilities of the pipeline system are intact and effective to ensure safety.
9. Flexible response to faults to ensure smooth operation
If the handle or handwheel is not flexible or cannot be opened and closed during use, the gland nut can be loosened appropriately to adjust the tightness of the valve. But be careful not to loosen it too much to avoid leakage or other problems. If the problem persists, contact professional technicians in time for treatment.
By following standard operations, paying attention to temperature changes, correct switching methods, timely handling of leakage, paying attention to medium characteristics, regular maintenance inspections, reducing vibration effects, paying attention to environmental factors, and flexibly responding to faults, we can effectively extend the service life of the fluorine-lined ball valve and ensure its stable and reliable operation.
