Lining fluorine pneumatic diaphragm valve design key points of the basic profile

a. Summary:
fluorine-butterfly pneumatic diaphragm valve is a special kind of pneumatic valves with truncation functions, in chemical engineering, acid, alkali, smelting, rare earth, pesticides and other industries production which has been widely applied in the system.
2. Design features:
. Fluorine-butterfly pneumatic valve and other pneumatic diaphragm valve is the biggest difference lies in: use without the structure of the stuffing box; Fluorine-butterfly pneumatic diaphragm valve diaphragm can make the flow passage of corrosive medium and all components of the drive is in a state of complete isolation, to keep the pneumatic valve usually 'run, run, drip, leak, etc.
. Due to the pneumatic diaphragm valve flow is smooth, small flow resistance, thus can obtain larger flow.
. Fluorine-butterfly pneumatic diaphragm valve pneumatic valve body cavity perfluorinated F for lining. Therefore has the characteristics of superior corrosion resistance.
. Because of the seal for elastic ptfe diaphragm. Therefore also has good sealing and minimum closing force.
. This pneumatic valve by pneumatic valve, pneumatic valve, pneumatic valve, pneumatic valve stem, the diaphragm and other drive components, etc.
. Pneumatic valve opening and closing is to achieve by rotating the handwheel. This pneumatic valve in the pneumatic valve cover the top with can see pneumatic valve opening or closing position display color, to indicate the pneumatic valve opening and closing of the trip. When placing the handwheel clockwise, the handwheel is down, pneumatic disc then drives the diaphragm down pathways truncate; The opposite of pneumatic valve is open, the color don't show.
. The pneumatic valve adopts standard: in accordance with the provisions of GB, and in accordance with BS
3. Use:
fluorine-butterfly pneumatic diaphragm valve is widely used in chemical, acid, alkali, smelting, rare earth, pesticides, dyes, medicine, papermaking, electroplating, electrolysis, pickling, radio, into a foil, scientific research institutions, defense industry and other industries strong corrosive medium under different working conditions, and can replace expensive rare metal pneumatic valves.
