Valve is a kind of commonly used hardware products, the valve in the assembly and installation process also has a certain skill requirements, otherwise the assembled valve may not show its own excellent performance, what are the skill requirements of the valve in the assembly process?
Valve pre-assembly treatment requirements:
1. According to the processing requirements, some parts need to be polished, and there can be no processing burrs on the surface;
2. All parts are degreased;
3. After the degreasing is completed, pickling and passivation will be carried out, and the cleaning agent does not contain phosphorus;
4. After pickling and passivation, rinse and clean with pure water, there can be no residue of chemicals, and carbon steel parts omit this step;
5. Wipe the parts one by one with non-woven fabrics, and do not retain the surface of the parts such as threaded hair, or blow dry them with clean nitrogen;
6. Wipe the parts one by one with non-woven fabric or precision filter paper dipped in pure alcohol until there is no dirty color.
Skills required for valve installation:
1. It is necessary to ensure that the installation workshop is clean, or a temporary clean area may be established, such as using newly purchased color striped cloth or plastic film, etc., to avoid dust entering during the installation process.
2. It is necessary for installation workers to wear clean cotton overalls, cotton hats, hair can not leak, feet wear clean shoes, hands wear plastic gloves, and degreasing.
