Sanitary Diaphragm Valve has the advantages of simple structure, beautiful shape, quick assembly and disassembly, flexible operation, small fluid resistance and reliable use. All steel parts of the sanitary diaphragm valve are made of acid-resistant stainless steel, and the seals are made of food silicone rubber or polytetrafluoroethylene, which meets the food hygiene standards.
Sanitary diaphragm valves are widely used in many industries such as food, brewing, beverages, dairy products, fine chemical pharmaceuticals and bioengineering. The sanitary diaphragm valve adopts a clamp type, which has the advantages of simple structure, beautiful shape, quick assembly and disassembly, rapid switching, flexible operation, small fluid resistance and reliable use.
Sanitary diaphragm valves are suitable for water, gas, oil and corrosion in chemical, petroleum, metallurgy, water heating, food, medicine and other industries. When we all operate sanitary diaphragm valves, we all need to understand the characteristics and uses of our diaphragm valves.
Sanitary diaphragm valves are stop valves that use diaphragms as opening and closing parts to close the flow channel, cut off the fluid, and separate the valve body cavity and the valve cover cavity. The diaphragm is usually made of elastic, corrosion-resistant and non-permeable materials such as rubber and plastic. So do you know what factors affect the service life of sanitary diaphragm valves?

The factors affecting the service life of sanitary diaphragm valves are introduced as follows:

1. Method to extend the service life of sanitary diaphragm valves by working at a large opening

Let the sanitary diaphragm valve work at a large opening as much as possible from the beginning, such as 90%. In this way, damage such as cavitation and erosion occurs on the head of the valve core. As the valve core is damaged, the flow increases, and the corresponding valve is closed a little more. In this way, it is continuously damaged and gradually closed, so that the entire valve core is fully utilized until the root of the valve core and the sealing surface are damaged.

2. Method to increase the service life of sanitary diaphragm valves by increasing the working opening

The sanitary diaphragm valve increases the loss of the system except the sanitary diaphragm valve, so that the pressure drop allocated to the valve is reduced. In order to ensure that the flow passes through the sanitary diaphragm valve, the opening of the sanitary diaphragm valve must be increased. At the same time, the pressure drop on the valve is reduced, so that cavitation and erosion are also weakened.

The orifice plate is set behind the sanitary diaphragm valve to consume the pressure drop; the manual valve in series on the pipeline is closed until the sanitary diaphragm valve obtains a more ideal working opening.
When we use our sanitary diaphragm valve, the service life of our sanitary diaphragm valve is the ones introduced above, and we need to know more about the above factors.
