Fluorine lined valve factory takes you to understand the internal structural design of fluorine lined valves

Fluorine lined valve is a widely used valve in modern petroleum and chemical industries. Its internal structure is different from conventional valves. Next, we will discuss it Fluorine lined valve factory Guide you to understand the internal structural design of fluorine lined valves.
1. For conventional valves, it is generally only necessary to consider the rationality of the structure and the processability of the casting process. However, for fluorine lined valves, in addition to these considerations, it is also necessary to consider issues such as the molding process of the fluorine lined plastic, production costs, and smooth flow channels.
2. The requirement for the internal structural design of fluorine lined valves is to be as clean as possible, with a flat lining and rounded transitions at corners.
3. If welding is used for the shell internals of fluorine lined valves, the welds must be designed as continuous welds and butt welds.
4. The fluorine plastic lining on the flange surface is required to be designed to fully cover the sealing surface, and in order to prevent shell damage, a design structure closely adjacent to the substrate is needed.
5. The thickness of the lining shall not be less than two millimeters.
6. The surface requirements of the lining layer are very high, it must be smooth and flat, without defects such as cracks, pores, and inclusions. The flange flange position and other corner positions require uniform color and no whitening phenomenon.
