How to judge whether the switch direction diagram of pneumatic butterfly valve cannot be closed in place and how to adjust it? 1. Recommended product: Sorrel carbon nano polymer material SD2240 cooperates with SD7111C for plugging under pressure;
2. Take safety protection measures for personnel during repair;
3. Check the surface of the leakage and remove the objects that affect the construction operation;
4. Neutralize the leakage point and clean it;
5. Remove the foreign matters and oxide layer on the repair surface, expose the true color, and reach clean and rough;
6. Strictly follow the mixing proportion of SD2240 materials, and fully mix until the color is uniform and there is no color difference;
7. Evenly apply Solay SD2240 material to the leakage part and its surroundings with a scraper to ensure tight bonding. To achieve the purpose of leak stopping, it may be necessary to repeatedly apply the material until there is no leakage;
8. After confirming that there is no leakage, thoroughly polish the surface around the material and clean it;
9. Mix evenly according to the material mixing proportion of Solay SD7111C without color difference; 10. Use Solay SD7111C to cover all SD2240 materials and bond them to the surface. The * * layer is thin and compacted with force to ensure bonding. If the repaired part bears high pressure, repeat to increase the material thickness and repair area of the repaired part;
11. If the repaired part needs to be reinforced, it shall be reinforced with Sorley carbon fiber cloth.
