What Is the Function of a Diaphragm Valve?

As a unique type of control valve, the diaphragm valve relies on the compression of the diaphragm to regulate the flow of liquid. With its excellent sealing performance, excellent corrosion resistance and long service life, the valve occupies an important position in many liquid transmission systems and plays the following key roles:

1. Flow control and regulation

The diaphragm valve can accurately control and regulate the flow of liquid by adjusting the degree of opening of the valve. When the valve is fully closed, the diaphragm valve can ensure a complete sealing effect and effectively prevent the leakage of liquid; when the valve is open, the liquid is allowed to flow smoothly and the flow rate can be flexibly adjusted.

2. Ensure the purity of the liquid

The diaphragm of the diaphragm valve has excellent sealing properties, which can effectively isolate the contact between the liquid and the external environment and prevent the liquid from being contaminated by the outside world. This feature makes the diaphragm valve widely used in application scenarios where high liquid purity needs to be maintained.

3. Prevent overflow and backflow

In the closed state, the diaphragm valve can ensure complete sealing and effectively prevent the overflow of the liquid; in the open state, through a specific design, the diaphragm valve can also prevent the reverse flow of the liquid and avoid the occurrence of backflow.

4. Adapt to high viscosity and easy-to-crystallize liquids

The special structural design of the diaphragm valve makes it suitable for the transmission of high viscosity liquids and easy-to-crystallize liquids. This feature effectively avoids the accumulation or crystallization of liquids inside the valve, ensuring smooth transmission of liquids.
