Product Details

D71F46 manual clamp type fluorine lined butterfly valve

Overview of D71F46 manual clamp type fluorine lined butterfly valve;

There are two basic types of butterfly valves in our factory: D71 series centerline butterfly valve and D73 series eccentric butterfly valve. The two-piece valve body combination is adopted, and the valve seat and valve body lining are integrated. When the valve works, only the full plastic valve seat and the plastic lining butterfly plate are in contact with the medium, and the valve can withstand the medium corrosion introduced by the lining material. The four pole sealing structure is adopted, and the sealing surface is equipped with a temperature resistant and aging resistant SI rubber elastic gasket, completely achieving zero leakage of the medium.
1、 Structural characteristics of D71F46 manual clamp type fluorine lined butterfly valve
1. The midline butterfly valve is concentric with the entire butterfly plate and valve seat within a 360 ° circumference (midline), with bidirectional sealing function, and pressure and flow can be freely adjusted;
2. The cam effect of the eccentric butterfly valve, which is a two-dimensional eccentric product, will generate sufficient sealing pressure in the sealing pair, and with the increase of working pressure, the sealing effect becomes more ideal;
3. Four level loading elastic seal ensures zero leakage inside and outside the valve.
a: Shaft and butterfly valve integrated outer lining F46;

b: The end face of the shaft head adopts a combination of elastic O-ring, rigid washer at the shaft shoulder, and elastic rubber pad;
c: The radial direction of the shaft adopts a combination of O-ring and metal shaft sleeve;
d: The valve seat is embedded in the valve body groove with elastic strips.
4. Using elastic gaskets for accurate positioning and simple structure. The use of O-rings is a safety measure to prevent accidental leakage.
