Rubber lined straight through diaphragm valve
Diaphragm valve structure form and the general valve is very different, is a new type of valve, is a special form of truncated valve, its opening and closing parts is a piece of soft material made of the diaphragm, the body cavity and the valve cover cavity and drive components separated, is widely used in various fields. Commonly used diaphragm valves are rubber lined diaphragm valve, fluorine lined diaphragm valve, unlined diaphragm valve, plastic diaphragm valve. Diaphragm valve structure is simple, fluid resistance is small, flow capacity is larger than other types of valves with the same specifications; No leakage, can be used for high viscosity and suspended particles medium regulation. The diaphragm separates the media FROM the upper chamber of the stem, so there is no packing and no leakage of media. However, due to the limitations of diaphragm and lining material, pressure resistance, temperature resistance is poor, generally only applicable to 1.6mpa nominal pressure and 150℃ below. Features :(1) fluid resistance is small. (2) can be used for medium containing hard suspended matter; Because THE MEDIUM IS ONLY IN CONTACT WITH THE BODY AND DIAPHRAGM, THERE IS NO FILLER BOX, NO FILLER BOX LEAKAGE, AND NO corrosion TO THE STEM part. (3) suitable for corrosive, viscous, slurry media. (4) can not be used in high pressure occasions.
