What Steps Are Required For Daily Maintenance And Regular Maintenance Of Linear Control Valves

The daily maintenance work of the linear travel control valve is divided into two parts: patrol inspection and regular maintenance. The patrol inspection work content is as follows.

1. Learn about the operation of the control valve from the process operator on duty.

2. Check the supply energy of the regulating valve and related accessories (air source, hydraulic oil or power supply,

3. Check the operation of the hydraulic oil system.

4. Check the static and dynamic sealing points of the regulating valve for leakage.

5. Check whether the connecting pipeline and joint of the regulating valve are loose or corroded.

6. Check the control valve for abnormal sound and large vibration, and check the supply.

7. Check whether the action of the regulating valve is flexible and whether it changes in time when the control signal changes

8. Listen to the valve core and valve seat for abnormal vibration or noise.

9. Contact and deal with problems in time.

10. Make records of patrol inspections and file them.

The contents of regular maintenance work are as follows:

1. Regularly clean the outside of the regulating valve.

2. Regularly adjust the regulating valve stuffing box and other sealing components, and replace the sealing components when necessary to maintain the sealing of static and dynamic sealing points.

3. Regularly add lubricating oil to the parts that need to be lubricated.

4. Regularly discharge and clean the air source or hydraulic filter system.

5. Regularly check the connection and corrosion of each connection point, and replace the connector if necessary.
