Problems with valves for transporting gasoline and diesel
Thread Content
Valves used for transporting gasoline and diesel often experience leakage of the valve core; how can this be resolved? Could the experts share their experience in solving this?
What type of valve is it? Are there impurities in the medium, and are filters installed in the piping system?
It could be that the medium contains hydrogen sulfide; in that case, using corrosion-resistant components for the valve core will prevent this problem. It’s also possible that the medium contains impurities, which can damage the sealing surfaces when the valve is opened and closed.
1. Determine the packing material. 2. Check for any corrosive components. 3. Perform regular inspections and maintenance on the valve: tighten the packing periodically and check for corrosion on the valve stem or clean it as necessary
It is said that abroad, valves usually come equipped with a mechanism for automatically compensating and compressing the packing, similar to an automatic oil filler
1. Install a filter in front of the valve. Even workshop-based enterprises conduct valve strength and sealing tests before shipping the products. Unless the valve starts leaking as soon as it is installed, use a valve made of appropriate material with a hard-seal design that has been treated to increase its hardness. Before purchasing a valve, confirm the material, temperature, and pressure.
3. It is also related to the direction in which your valve is installed. For example, if you go beyond the correct installation direction of the valve – vertically or at an angle. If you have any questions, please send a private message with the specific parameters of the valve used in that location. I’ll help you answer it slowly
