Diaphragm valve lined with fluorine

Diaphragm valves are used most often when working with fluids that contain large amounts of particulate matter. The design of these valves makes it possible to avoid the formation of plaque, which is formed from the precipitation of solid particles in the filter results. Especially with fluids that contain large amounts of the solid phase.

Diaphragm valves are also called valves. Its distinguishing feature is that the saddle paddle is made at the end of the partition, which is installed across the axis of flow of the liquid. The role of the spool performs a flexible membrane. Such a membrane under the influence of the spindle or rod bent to overlap the passage section of the pipeline. Thus, flexible membrane capable of sealing the cavity of the valve, therefore, the presence of a seal is not required. Typically, diaphragm valves are used for pumping salt solutions and aggressive media of the heat power stations in chemical systems training.

Diaphragm valve consists of such parts as body, head vent and elastic material. The membrane serves to protect the driving all functional parts of the valve from the product being pumped. Moreover, due to the membrane on these items eliminated the formation of deposits that lead to deterioration of reliability of components, and can also cause the valve to malfunction.

In order to maintain the valve in operating condition, it is necessary to carry out the replacement of the membrane. Besides it is not necessary to disconnect the housing from the pipeline, and replacement of the diaphragm is produced in a short time.

Besides, with the working medium is in contact exclusively the membrane and the housing, so the diaphragm valve may be used as in the chemical industry and in sterile production. However, when selecting materials for the valve design should consider the environment in which it will be applied.
