Cleaning fire protection valves (such as 3C fire dampers) requires selecting methods based on component types, focusing on removing grease and dust while avoiding damage to blades or fins. Specific steps are as follows:
Filter Screen Cleaning
Water Wash: Rinse surface dirt from the filter screen with clean water. For oil stains, soak in a mild alkaline cleaner and thoroughly rinse until no residue remains.
Fin Cleaning
Light Contamination: Use a high-pressure air hose to blow away dust from the fin surfaces.
Heavy Contamination: Spray a specialized fin cleaning solution, let it sit, then rinse with clean water until the metal surface is restored to its original color.
Precautions
Avoid forceful cleaning: Excessive force may cause blade deformation or breakage. Handle gently.
Regular maintenance: Inspect quarterly to ensure valves operate smoothly without rust or blockages.
