The Fluorine-lined Valve Factory Takes You To Understand The Internal Structure Design Of Fluorine-lined Valves

Lined Valve is a valve widely used in modern petroleum and chemical industries. Its internal structure is different from that of conventional valves. Next, the fluorine-lined valve factory will take you to understand the internal structure design of fluorine-lined valves.
1. For conventional valves, it is generally enough to consider whether the structure is reasonable and the processability of casting. For fluorine-lined valves, in addition to these, the molding processability, production cost and smooth flow of fluorine-lined plastics must be considered.
2. The internal structure design requirements of fluorine-lined valves are as neat as possible, the lining is flat, and the corners should be arc-shaped.
3. If the shell internals of fluorine-lined valves are welded, the welds must be designed as continuous welds and butt welds.
4. The fluorine-lined plastics on the flange surface are required to be designed to line the sealing surface, and in order to prevent the shell, a design structure close to the base is required.
5. The lining thickness 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 and other corners must be uniform in color without any whitening.
