Fluorine-butterfly butterfly valve according to the connection way classification ( 1) Flanged butterfly valve ( 2) The wafer butterfly valve ( 3) The lug butterfly valve ( 4) Welded butterfly Industrial Valves fluorine-butterfly butterfly valve's note: 1. Due to multi-layer soft fold type sealing ring is fixed on the valve plate, when the valve plate normally open state media on the sealing surface to form positive wash, after flushing, directly affect the sealing performance. 2, restricted by structure conditions the structure does not adapt to do under the path DN200 valves, because the valve plate structure is too thick, large flow resistance. Fluorine-butterfly butterfly valve product use: D371F46 wafer fluorine-butterfly butterfly valve used in - 50 ℃ ~ 150 ℃ of aqua regia, various concentration of sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acid, strong acid, strong oxidizer, FEP also apply to all kinds of organic solvent concentration of alkali and other corrosive gas and liquid medium used on the pipeline. Fluorine-butterfly butterfly valve features: when the current state, the Industrial Valves plate and valve seat seal between the valve plate by the drive torque pressure to the valve seat. As the reverse medium pressure increases, the unit is pressure between the valve plate and valve seat is less than the pressure of medium, the adjusting ring after the loading of the spring deformation energy stored by compensating valve plate and valve seat sealing surface of the tight pressure automatic compensation effect. So the utility model is not like the existing technology, soft hard multi-layer sealing ring, installed in the valve plate directly installed on the valve body, in the middle of the plate and seat add adjustable ring is the ideal way of two-way hard seal. It will replace gate Industrial Valves and ball valve. In this paper, the keyword search: more technical articles valve product supply information
