Valves are a kind of commonly used hardware products. Valves also have certain technical requirements before assembly and assembly. Otherwise, the assembled valves are not able to reflect their excellent performance. What are the valves in the assembly process? Technical requirements?
Pre-assembly requirements for valve assembly:
1. According to the processing requirements, some parts need to be polished, the surface can not be processed burrs, etc.; 2, all parts are degreased;
3. After the degreasing is completed, the acid washing and passivation are carried out, and the cleaning agent does not contain phosphorus; 4. After pickling and passivation, it is rinsed with pure water, and there is no residue of the drug, and the carbon steel parts are omitted; 5, one by one The fabric is wiped dry, and the surface of the parts can not be left by wire, or dried with clean nitrogen; 6. Wipe the parts one by one with non-woven fabric or precision filter paper, until there is no dirty color.
Technical requirements for valve assembly:
1. The installation workshop must be clean, or set up a temporary clean area, such as the use of newly purchased color strips or plastic film to prevent dust from entering during the installation process.
2, the assembly workers must be dressed in clean cotton overalls, wearing a cotton cap, hair can not leak, wear clean shoes, hand wearing plastic gloves, skim.
3. The assembly tool must be degreased and cleaned before assembly to ensure cleanliness.

PVD (physical vapor deposition) coating is a type of Surface Treatment that is used to improve the performance of metal parts, by applying a thin layer of material onto the substrate through a vacuum chamber. This process provides a range of benefits, including increased hardness, improved wear resistance, and enhanced corrosion resistance.
PVD coatings are typically applied to metals such as stainless steel, titanium, and aluminum. They are particularly useful in applications where the substrate is subjected to high wear and tear, as the coatings help to reduce friction and limit the damage caused by abrasion. They are also used in the automotive industry to provide an aesthetic and functional finish to exterior parts.
PVD coatings can be tailored to meet specific application requirements, with a range of coating materials available, including titanium, chromium, and zirconium. These coatings can be deposited in a range of colors, such as black, gold, and silver, giving designers and manufacturers the flexibility to create parts with the desired appearance.
Another key benefit of PVD coating is its durability. The thin layer of coating can offer a long-lasting, high-performance finish, even in harsh or corrosive environments. This makes them particularly useful in outdoor applications, and in settings such as aerospace and medical devices, where reliability and durability are critical.
PVD coating is applied through a series of steps, including cleaning and pre-treatment of the substrate, coating material deposition, and post-treatment, such as polishing or annealing. The result is a thin, uniform layer of coating that provides a range of functional and aesthetic benefits.
In conclusion, PVD coating is a versatile and effective surface treatment for metal parts. It offers a range of benefits, including improved hardness, wear resistance, and corrosion resistance, as well as aesthetic options. By enhancing the performance and durability of metal parts, PVD coating plays an important role in improving the reliability and efficiency of a range of industries and applications.
