Overview:
Fluorine-lined diaphragm valve is a special type of valve with shut-off function, which is widely used in the production system of chemical industry, acid, alkali, smelting, rare earth, pesticide and other industries.
Design Feature
1. The biggest difference between the fluorine-lined diaphragm valve and other valves is that it adopts a structure without a stuffing box; the fluorine-lined diaphragm valve diaphragm can completely isolate the corrosive medium in the flow path from all driving parts, thereby eliminating the usual valve The disadvantages of “running, risking, dripping, leaking” and so on.
2. Since the flow path of the diaphragm valve is smooth and the flow resistance is small, a larger flow rate can be obtained.
3. The inner cavity of the fluorine-lined diaphragm valve is perfluorinated lining. Therefore, it has superior corrosion resistance.
4. Because the seal is a flexible tetrafluoroethylene diaphragm. Therefore, it also has better sealing and minimal closing force.
5. This valve is composed of valve body, valve bonnet, valve disc, valve stem, diaphragm and other driving parts.
6. The opening and closing of the valve is achieved by rotating the hand wheel. This valve is marked on the upper end of the valve cover with a display color that can see the opening or closing position of the valve to indicate the opening and closing stroke of the valve. When the handwheel is placed clockwise, the handwheel will move down, and the valve disc will then drive the diaphragm down to cut off the passage; otherwise, the valve will open and the color will be revealed.
7. This valve adopts the standard: in accordance with the provisions of GB12239 and in line with BS5156
Use:
Fluorine-lined diaphragm valves are widely used in different working conditions in the chemical industry, acid making, alkali making, smelting, rare earth, pesticides, dyes, medicine, papermaking, electroplating, electrolysis, pickling, radio, chemical foil, scientific research institutions, national defense industry and other industries. Strong corrosive medium, and can replace expensive rare metal valves.
