The following are some key points for maintaining the Pneumatic Dust Butterfly Valve:
1. Appearance and connection maintenance
Cleaning the surface: Regularly use a clean soft cloth or compressed air to remove dust, oil and other impurities on the valve surface to prevent these pollutants from entering the valve and affecting its performance. For stubborn stains, you can use a mild detergent to wipe, but avoid the detergent from contacting the valve's sealing surface and moving parts.
Check the connection parts: Frequently check the valve's flanges, bolts and other connection parts to ensure that the connection is firm and there is no looseness or leakage. If the bolts are found to be loose, they should be tightened in time according to the specified torque; if the flange sealing surface is damaged or deformed, it needs to be repaired or replaced in time to ensure the sealing performance.
2. Maintenance of sealing parts
Check the sealing surface: Regularly check the sealing surface of the butterfly plate and the valve seat to check for wear, scratches, corrosion and other damage. If the sealing surface is slightly damaged, it can be repaired by grinding; if the damage is serious, the seal needs to be replaced.
Keep the sealing surface clean: prevent dust, particles and other impurities from adhering to the sealing surface to avoid affecting the sealing effect. Before closing the valve, the pipeline can be properly purged to remove impurities in the pipeline.
3. Maintenance of pneumatic actuators
Check the air source: ensure that the air source is dry and clean, and regularly discharge the accumulated water and impurities in the air filter to prevent moisture and impurities from entering the pneumatic actuator, causing the parts to rust and clog. At the same time, check whether the air source pressure is stable and within the specified range. If the pressure is abnormal, the air source system should be adjusted or repaired in time.
Lubricate the actuator: According to the requirements of the equipment manual, regularly add an appropriate amount of lubricant to the moving parts of the pneumatic actuator, such as the cylinder piston, push rod, etc., to reduce friction and ensure the actuator is flexible.
Check the feedback device: For pneumatic butterfly valves with position feedback devices, check whether the connection line of the feedback device is loose and whether the feedback signal is accurate. If there is any abnormality, adjust and repair it in time.
4. Regular maintenance and testing
Regular comprehensive inspection: At regular intervals, conduct a comprehensive inspection of the valve, including the opening and closing action of the valve, the rotation flexibility of the butterfly plate, and the sealing performance.
Performance test: Regularly perform valve performance tests, such as leakage tests, switch time tests, etc., to ensure that the valve performance meets the requirements.
