The three-way load check valve achieves forced sealing by applying pressure to the valve disc to prevent medium leakage. It not only has a load stop function, but also can regulate, guide, prevent backflow, stabilize, divert or overflow.

Safety precautions and daily maintenance and inspection during the use of three-way load check valves:

　　Safety precautions during operation

1. Slow operation:

When opening or closing the valve, the handwheel should be slowly rotated to avoid excessive force that may damage the valve or sealing surface.

2. Avoid overload:

Do not keep the valve in an overloaded state for a long time to avoid damage to the valve.

3. Pay attention to the state of the medium:

Before operation, it should be confirmed whether the state of the medium (such as temperature, pressure, etc.) is within the allowable range of the valve.

4. Avoid medium backflow:

For situations where it is necessary to prevent medium backflow, it is necessary to ensure that the valve is tightly closed to prevent accidents caused by medium backflow.

5. Personal protection:

Operators should wear appropriate personal protective equipment such as gloves, goggles, etc. to prevent media splashing or accidental injury.

　　Daily maintenance and inspection

1. Regular inspection:

Regularly check the sealing performance and working condition of the valve. If any leakage or abnormal situation is found, it should be dealt with in a timely manner.

2. Replace vulnerable parts:

Replace vulnerable parts such as sealing rings and valve discs as needed to ensure the sealing performance and service life of the valve.

3. Cleaning and lubrication:

♦ Regularly clean the impurities and sediments inside the valves and pipelines to maintain the cleanliness and smoothness of the valves.

♦ Apply an appropriate amount of lubricant to the transmission components of the valve as needed to reduce friction and wear.
