First, product overview
The opening and closing of the J45 straight-flow fluorine lined stop valve is achieved by rotating the handwheel to make the stem move axially and drive the valve disc to rise and fall. The disc drops when the hand wheel rotates clockwise. Dc fluorine lined stop valve in the pipeline is mainly used to connect or cut off the medium in the pipeline, but can not be used for throttling.
The surface of the valve body cavity and the surface of the valve cover, disc, stem and other parts in contact with the medium are lined with polyfluoroethylene propylene plastic. Therefore, it has the best corrosion resistance. Suitable for a variety of concentrations of hydrochloric acid, sulfuric acid, hydrofluoric acid and aqua roya, nitric acid, various organic acids, strong alkali, strong oxidant or dilute alternations, acid-base alternations, a variety of organic concentrated agents and other strong erosive media.
FEP(F46), PCTFE(F3) lined fluorine DC cut-off valve is suitable for all kinds of concentrations of aqua king, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP is also suitable for all kinds of concentrations of strong alkali organic solvents and other corrosive gases, liquid media pipeline use.
Second, the basic structure of J45 straight flow lined fluorine globe valve
1, fluorine plastic lining J41F46 straight through type, J45F46 straight flow lined fluorine globe valve, J44F46 Angle globe valve, with compact structure, flexible opening and closing, strong corrosion resistance, short stroke (generally nominal diameter 1/4) and other advantages, is widely used in petroleum, chemical and other piping system to do truncation medium. But it needs to be emphasized that the fluorine plastic lined globe valve is strictly prohibited to be used for flow regulation, so as not to destroy the sealing surface by the high speed medium flow erosion generated at the throttle outlet.
2, disc and stem design as a whole structure, to prevent the possibility of internal parts out of the valve body due to pipeline pressure fluctuations, compact structure, safe use.
