I. Overview of G41F fluorine-lined diaphragm valve :
Diaphragm valve is a special form of valve with cut-off function. Its unfortunate closure is composed of a steel disc and a diaphragm made of soft material (composite of rubber and fluoroplastic). The cavity is separated to achieve the purpose of cutting off the medium in the tube.
G41F fluorine-lined diaphragm valve has the following characteristics:
The basic series of diaphragm valves are fully lined G41F46, EG41F46, weir type and G45F46 DC type.
1. The composite diaphragm valve separates the lower cavity of the valve body from the inner cavity of the valve cover and forms a direct current channel with it, so that the internal parts such as the valve stem and the valve disc of the upper diaphragm are completely isolated from the medium, and the packing seal structure is omitted. Can avoid both internal and external leakage;
2. The valve with Teflon fluoroplastic lining layer made of FEP (Teflon) fluoroplastic and full rubber composite diaphragm can be suitable for various strong corrosive media except "melt alkali metal, elemental fluorine".
3. As the diaphragm of the actuator, due to frequent opening and closing, fatigue fracture is prone to occur. It should be replaced periodically according to the working conditions and the characteristics of the medium.
4. The anticorrosive performance of fluoroplastics and the recommended temperature wind "Performance table of fluoroplastic linings for valves and pipeline accessories".
