the diaphragm Industrial Valves according to structure form, the kinds of diaphragm valve can be divided into the following types:

the characteristics of the diaphragm Industrial Valves

1) because of a diaphragm, make located above the diaphragm valve cover, stem, disc, etc from the medium corrosion, also won't produce medium leakage; Without packing, simple structure, convenient maintenance.

2. Limited by the diaphragm material, using range is small, only used for low pressure, the temperature is not high.

the structure of the diaphragm valve diaphragm valve is mainly composed of valve body, valve cover, stem, diaphragm, disc, lining layer and transmission device, etc. Figure 2 - 36 is a common roof lining type diaphragm valve.

the body structure of the commonly used roof type. In addition to cut-off ( Figure 2 - 37) And ram ( Figure 2 - 38) And so on, but rarely used. The body such as integral casting and forging welding structure, also can use all sorts of corrosion resistant material or cast iron, cast steel liner to capture porcelain, rubber, plastic, etc.

typical diaphragm Industrial Valves structure typical diaphragm valve structure as shown in figure 2 39.
