Selection and usage precautions of German standard F6 rotary check valve

The German standard F6 rotary check valve is a commonly used valve in pipeline systems, mainly used to prevent medium backflow. Here are some precautions when selecting and using:

Selection precautions:

1. Type of medium:

-Determine the properties of the fluid (such as water, oil, gas, etc.) and select suitable materials and structures.

2. Pressure level:

-Select the corresponding pressure level based on the working pressure of the system to ensure reliable operation of the valve under working pressure.

3. Temperature range:

-Understand the working temperature of the medium and select valve materials suitable for this temperature range.

4. Caliber:

-Select the appropriate check valve based on the diameter of the pipeline to ensure normal flow.

5. Installation method:

-Confirm the installation method (such as horizontal or vertical) to ensure that the valve can be installed correctly.

6. Flow direction:

-The swing check valve has a clear flow direction, ensuring that the arrow indication is followed during installation.

7. Sealing performance:

-Choose appropriate sealing materials as needed to improve sealing performance and prevent leakage.

8. Brand and Certification:

-Choose a reputable brand to ensure that the product has relevant certifications and quality assurance.

Precautions for use:

1. * * Regular Inspection * *:

-Regularly check the working status of the check valve to ensure its normal operation and prevent system problems caused by malfunctions.

2. Clean the pipeline:

-Before installing the check valve, ensure that there are no impurities in the pipeline to avoid affecting the normal operation of the valve.

3. Avoid vibration:

-Pay attention to the fixing of check valves in high-frequency vibration environments to avoid damage caused by vibration.

4. Preventing water hammer:

-When designing pipeline systems, consider the phenomenon of water hammer and take necessary measures (such as installing buffers) to prevent impact on valves.

5. Follow installation specifications:

-Install according to the installation manual provided by the manufacturer to ensure the effectiveness and reliability of the valve.

6. Operating environment:

-Pay attention to the environment around the valve to ensure that there are no corrosive gases or liquids that may cause damage to the valve.

7. Avoid frequent opening:

-Swing check valves are suitable for one-way flow and should not be opened frequently to avoid affecting their service life.

By following the above selection and usage precautions, the efficiency and reliability of the German standard F6 rotary check valve can be effectively improved.
