What Are The Basic Structures Of Fluorine-lined Ball Valves?

The basic series of Sanitary Ball Valve is Q41F46, which can be divided into two structural types: split type and three-piece type. In addition to the simple fluid resistance structure, what are the basic structures of fluorine-lined ball valves?

The basic structure of the fluorine-lined ball valve is introduced as follows:
1. The ball valve with FEP lining has high chemical stability and can be used for any other highly corrosive properties except "molten alkali metals and elemental fluorine";
2. With full-bore, floating ball structure, the valve can be closed without leakage in the entire pressure range, which is more convenient for ball sweeping and pipeline maintenance of the pipeline system;
3. The opening and closing ball and valve stem are cast (forged) as one, eliminating the possibility of the valve stem rushing out of the pressure-bearing part due to pressure changes;
4. The structure is compact and reasonable, the inner cavity space of the valve body reduces the medium retention, and the special molding process makes the sealing surface density good;
5. The two-piece and three-piece structures can adapt to various pipeline systems and working conditions with different requirements. Among them, the three-piece ball valve allows the main valve body to be separated from the valve bodies on both sides, which can realize online rapid replacement and maintenance.
The inner cavity and ball of the fluorine-lined ball valve are lined with corrosion-resistant and aging-resistant fluoroplastics using high-pressure injection molding technology, which has reliable corrosion resistance and sealing. It is widely used in chemical, petroleum, pharmaceutical and other industrial sectors to adjust or cut off strong corrosive media such as acids and alkalis in the production process, and is used in water treatment process control.
