Application scenarios in petroleum refining
The petroleum refining process involves high temperatures, high pressures and corrosive media, which places extremely high demands on the performance of valves. The DBB ball valve is suitable for a variety of media, including aviation kerosene, light oil, natural gas and chemical media. Its specific application scenarios include:
Pipeline isolation: During pipeline maintenance or emergency repair, the DBB ball valve can reliably isolate the medium in the pipeline to ensure the safety of maintenance personnel.
Equipment maintenance: During the overhaul of refining equipment, the DBB ball valve ensures that the medium inside the equipment is completely emptied through its double block and bleed function to avoid accidental leakage.
Medium switching: In a multi-medium transportation system, the DBB ball valve can effectively prevent cross-contamination between different media and ensure the safety of the process flow and product quality.
The structural design of the DBB ball valve enables it to maintain stable operation under complex working conditions. Its movable valve seat can automatically adjust the sealing state when the pressure changes, reducing sealing failure caused by pressure fluctuations.
DBB ball valves are usually made of high-temperature-resistant and corrosion-resistant materials such as 316L stainless steel and polytetrafluoroethylene (PTFE). These materials can withstand the harsh environment in the petroleum refining process.
In extreme cases such as fires, the fireproof design of the DBB ball valve can ensure that the valve can still maintain sealing at high temperatures and prevent medium leakage from causing greater accidents.
