Maintenance and treatment of corrosion-resistant pneumatic ball valve The use of corrosion-resistant pneumatic ball valve shall specify the applicable medium and scope, and select appropriate materials and gaskets for production. Before the maintenance of the pneumatic ball valve, the upstream and downstream pipeline pressure must be removed before disassembly. The disassembled parts can be cleaned by immersion. The non-metallic parts shall be taken out of the cleaning agent as soon as possible after cleaning, and shall not be soaked for a long time. The online maintenance of pneumatic ball valve requires the operation of a qualified leak stoppage engineer under pressure, and the maintenance steps can refer to Xinqing Environmental Protection's Pneumatic Ball Valve Leak stoppage Operation Manual under Pressure.

3、 Strictly control the quality of warehousing raw materials
To avoid the deterioration of raw materials in storage is the continuation of the process of raw material purchase. The key to Tongfeng pneumatic butterfly valve is to do the following disposal work.
1. Disposal of warehousing raw materials. The inventory of raw materials, especially Class A raw materials, should be checked frequently to achieve the "ten no's", that is, no damp, no rot, no rust, no mildew, no rot, no change, no damage, no freeze, no damage, no moth.
2. Disposal of warehouse environment. The shelves and articles in the warehouse should be placed reasonably, the corridor should be clear, the doors and windows should be free of damage, and the "three cleans" (on the ground, doors and windows, shelves) should be achieved, without sundries, waste, and dust.
3. Stacking and confession of raw materials in the warehouse. Stacking and confession are also a major aspect to ensure the quality of raw materials in the warehouse. It is necessary to stop reasonable stacking and confession of raw materials in stock according to their functions and storage requirements. Special consideration shall be given to the functions of Class A raw materials, packaging quality and the ground conditions of the warehouse, and proper stacking methods shall be adopted to reach the flood control and moisture-proof purpose.
4. View of raw materials. When raw materials enter the warehouse, they shall be inspected and stacked together, and the maintenance operation shall be stopped according to the classification of raw materials and maintenance needs, that is, regular or frequent inspection shall be stopped to eliminate and deal with hidden dangers in a timely manner.
5. Warehouse out disposal of raw materials. The principle of "first in, first out" should be followed, especially for the raw materials that are difficult to view due to the long storage period and large cargo piles. Such raw materials should be delivered in a timely manner. At the same time, standardize the actions of the warehousing process to avoid harm to the quality of raw materials caused by the handling process.
