How To Ensure One-way Flow Of Sanitary Check Valves?

The key to ensuring the one-way flow of Sanitary Check Valve lies in its design and working principle. The following are several key points to ensure the one-way flow of sanitary check valves:

Working principle:

The working principle of sanitary check valves mainly relies on the weight of its opening and closing parts (valve discs) and the medium pressure to achieve automatic opening and closing.

When the medium flows in from the inlet end, the valve disc is pushed open under the action of the medium pressure, and the medium can flow.

Once the medium flows back or the inlet pressure drops below the sum of the weight of the valve disc and its flow resistance, the valve disc will quickly close under the action of its own weight and the medium pressure, thereby effectively preventing the medium from flowing back.

Valve disc design:

The valve disc is a key component of the sanitary check valve, and its design directly affects the one-way flow performance of the valve.

The valve disc is usually round or in a shape suitable for fluid flow to ensure smooth opening in forward flow and tight closing in reverse flow.

Sealing performance:

The sealing performance of the sanitary check valve is crucial to preventing the medium from flowing back.
When the valve is closed, a reliable seal should be formed between the valve disc and the valve seat to prevent leakage of the medium.
To ensure the sealing performance, the valve disc and valve seat are usually made of corrosion-resistant and wear-resistant materials, and are processed and polished with high precision.

Installation and maintenance:

Correct installation and maintenance are also important factors to ensure the unidirectional flow of sanitary check valves.
During installation, the direction of the valve should be correct, that is, the inlet end is consistent with the flow direction of the medium.
Regularly check the sealing performance and appearance damage of the valve, and replace damaged or aging parts in time to ensure the long-term stable operation of the valve.

In summary, through reasonable working principles, valve disc design, sealing performance, and correct installation and maintenance, the sanitary check valve can achieve unidirectional flow and effectively prevent the backflow of the medium.
