Sanitary diaphragm valve service life factors

Sanitary diaphragm valve is a diaphragm as the opening and closing parts of the closed flow path, cut off the fluid, and the valve body cavity and the valve cover cavity separated from the globe valve. Diaphragm commonly used rubber, plastic and other elastic, corrosion-resistant, non-permeable materials. So you know what are the factors of sanitary diaphragm valve service life?

 

Sanitary diaphragm valve service life factors are introduced as follows:

 

1, sanitary diaphragm valve large opening work to extend the life of the law

Let the sanitary diaphragm valve at the beginning as much as possible in the large opening degree of work, such as 90%. In this way, vapor corrosion, erosion and other damage occurs on the head of the spool. With the destruction of the spool, the flow rate increases, the corresponding valve and then close a little, so that the continuous destruction, gradually closed, so that the entire spool all fully utilized, until the spool root and sealing surface damage.

 

2, sanitary diaphragm valve to increase the work opening to improve life method

 

Sanitary diaphragm valve to increase the system in addition to the loss of sanitary diaphragm valve, so that the distribution of the valve on the pressure drop is reduced, in order to ensure that the flow through the sanitary diaphragm valve, is bound to increase the sanitary diaphragm valve openness, at the same time, the valve on the pressure drop is reduced, so that the cavitation, scouring corrosion is also weakened.

 

Sanitary diaphragm valve valve set up after the orifice plate throttling consumption of pressure drop; close the pipeline series of manual valves, to the sanitary diaphragm valve to obtain a more ideal work opening.

 

We all in our sanitary diaphragm valve use, for our sanitary diaphragm valve service life is introduced above these, we need to know more about these factors above!
