The safe use of fluorine lined valves is the key to safe production

Fluorine lined valve As an indispensable component in current industrial pipelines, there are many precautions to be taken when using the product. A thorough understanding of the purpose of fluorine lined valve products is beneficial for improving work efficiency and addressing various situations that may arise during use. We know that fluorine lined valve products are relatively expensive compared to other valve products, mainly because their usage environment is harsh. Improper use can lead to relatively serious accidents. Therefore, the correct use of fluorine lined valve products is the key to safe production. When using fluorine lined valve products normally, we should pay attention to the following points:
1. Before use, carefully read the product manual.
2. Apply the pressure specified on the nameplate or instruction manual Temperature Use within the scope of the medium.
3. When using, prevent the fluorine lined valve from generating excessive pipeline stress due to temperature changes, minimize temperature changes as much as possible, and add U-shaped expansion joints before and after the valve.

4. For pipelines with self igniting media, measures should be taken to ensure that the ambient temperature and operating temperature do not exceed the self ignition point of the media, in order to prevent danger caused by sunlight exposure or external fires.
5. Regarding toxicity Flammable Explosive Fluorine lined valves on pipelines with highly corrosive media are strictly prohibited from replacing the packing under pressure. Although fluorine lined valves have sealing functions in their design, it is not recommended to replace the packing under pressure.
6. For some media that are unstable and prone to decomposition (such as the decomposition of certain media causing volume expansion and abnormal increase in working pressure), measures should be taken to eliminate or limit the factors that cause valve damage or leakage. When selecting valves, consideration should be given to the possible changes in operating conditions caused by unstable and easily decomposed media, and fluorine lined valves with automatic pressure relief devices should be selected.
7. It is prohibited to use levers to open and close fluorine lined valves. Pay attention to the opening and closing indication position and limit device of the fluorine lined valve. After the opening and closing are in place, do not forcefully close it to avoid premature damage to the fluorine plastic sealing surface.
During the use of fluorine lined valves, the sealing surface of fluoroplastic is often prone to crystallization due to the soft texture of the medium Solid particles can damage the sealing surface, causing seal leakage. If discovered, promptly repair or replace the sealing components.

9. Measures should be taken to eliminate severe and long-term vibrations in pipelines to avoid damage to fluoroplastic lined valves.
10. Generally, gaskets are not added to the flange of fluorine lined valves. If there is leakage at the middle flange, tighten the middle flange nuts evenly to eliminate the leakage. If the sealing surface of the Sino French seal is damaged, repair the sealing surface and add a flange gasket to solve the problem.
11. Some fluorine lined valves Fluorine-lined ball valve During use, some parts are opened for regulating flow, and high-speed media may cause premature damage to the sealing surface. In such cases, the sealing components should be replaced in a timely manner.

If the handle or handwheel does not rotate flexibly or cannot open and close the fluorine lined valve, the gland nut can be loosened appropriately. The rotation is still not flexible. It may be that the pressure cap is skewed, it needs to be adjusted correctly. After adjusting and loosening the gland, it is still not possible to flexibly open and close the fluorine lined valve. It should be disassembled for inspection, cleaned of dirt, and troubleshooting. When disassembling such fluorine lined valves, attention should be paid to the medium in the pipeline of the fluorine lined valve, whether it has been used or newly installed. If the medium used is toxic Flammable Explosive substances, workers should wear protective masks and rubber gloves, wear protective clothing, and operate according to operating procedures. To avoid accidents during disassembly and prevent accidents from occurring.

Fluorine lined valve products, as important components in the industrial industry, have a wide range of applications and are highly favored by users and users. They are a promising product. Therefore, please pay attention to the above points during use to ensure safety production.
