Control valves are important equipment in industrial control systems. To ensure the long-term reliability and efficiency of control valves, routine maintenance is essential. The following is an introduction to routine maintenance of control valves by วาล์วเดลโก้.
What is a control valve
A control valve is a type of valve utilized to regulate the flow, pressure, temperature, liquid level, and other process variables in industrial automation processes. It automatically adjusts the valve opening based on control signals within the automation system to manage the flow, pressure, temperature, and liquid level of the medium.
Daily maintenance of control valves
- Regularly check the feedback lever: Ensure that the feedback lever is firm to avoid loosening or falling off, in order to maintain the control accuracy of the valve.
- Keeping the valve clean: Regular cleaning of the valve ensures that the appearance and function are not affected by dirt, prolonging service life and reducing the risk of malfunction.
- Check and maintain mechanical gears: Regularly check the mechanical gears to ensure flexible and reliable operation, and lubricate and maintain them in time if there is any stuck phenomenon.
- Drainage and waterproofing: Regularly drain to prevent water accumulation, and ensure that the rain cover is covered to avoid damage to the valve by rainwater intrusion.
- Check the pressure gauge and air source pressure: Check the damage of the pressure gauge to ensure that the pressure of the gas source meets the rated value, to avoid affecting the normal operation of the regulating valve.
- Check valve sealing: Confirm that there is no leakage at the inlet, anti-corrosion treatment of bolted joints, and maintenance of valve sealing.
- Check the membrane head and gas source pipe: Regularly check the diaphragm head and air source pipe to maintain the sealing and ensure the performance of the regulating valve.
- Lubricate moving parts: Regularly lubricate the moving parts of the valve to minimize wear and improve efficiency.
- Check packing: Find packing leakage and replace it in time to ensure valve sealing and regulating performance.
- Check the fixing condition: Confirm that the valve is firmly fixed to avoid vibration problems and ensure stable system operation.
- Check valve cover: Check whether the contact surface of the upper valve cover is leaking and repair the leakage to ensure stable operation.
- Confirm handwheel position: Check the handwheel position and record the automatic position to guarantee normal operation under automatic control.
Conclusion
These simple maintenance steps will improve the reliability and performance of the control valve and ensure stable system operation. Timely checking and upkeep can prevent potential issues and enhance the overall performance of the equipment.
