Valves are among the most commonly used hardware components in various industrial applications. To ensure their optimal performance, they must meet specific technical requirements before and during the assembly process. Proper preparation and adherence to strict guidelines are essential for achieving high-quality results. So, what are the key steps and technical requirements involved in valve assembly?
**Pre-Assembly Requirements for Valves:**
1. Parts must be carefully polished according to processing specifications to remove any burrs or imperfections on the surface.
2. All components should be thoroughly degreased to eliminate oils and contaminants that could affect performance.
3. After degreasing, acid washing and passivation are performed to enhance corrosion resistance, ensuring that no phosphorus-containing cleaning agents are used.
4. Following pickling and passivation, parts must be rinsed with pure water until all chemical residues are completely removed, except for carbon steel parts.
5. Each part should be wiped dry using non-abrasive materials such as clean cloth or precision filter paper, avoiding any fiber residue. Alternatively, they can be dried with clean nitrogen gas.
6. Finally, each component should be cleaned with non-woven fabric or high-quality filter paper until no dirt remains, ensuring a spotless finish.
**Technical Requirements During Valve Assembly:**
1. The assembly area must be kept extremely clean. If necessary, a temporary clean zone should be set up using new plastic films or color strips to prevent dust contamination during the process.
2. Workers must wear clean cotton overalls, caps, and gloves made of soft material to avoid hair or fibers from getting into the components. They should also wear clean shoes and use plastic gloves when handling parts.
3. All assembly tools must be thoroughly cleaned and degreased before use to maintain the integrity of the components and prevent contamination.
