Fluorine-lined diaphragm valve is a special form of cut-off valve, which appeared in the 1920s. Its opening and closing part is a fast diaphragm made of soft material, which separates the inner chamber of the valve body from the inner chamber of the valve cover and the driving parts, so it is called diaphragm valve.
The most prominent feature is that the diaphragm separates the inner chamber of the lower valve body from the inner chamber of the upper valve cover, so that the parts such as the stem and disc above the diaphragm are not corroded by the medium, so that the packing sealing structure is omitted and the leakage of the medium is not produced. It is the most ideal anticorrosive material in the world, and has been widely used in large-scale equipment and pipelines for rotary forming. Internal lining.
