Introduces a pneumatic valve assembly technology requirements

the development of pneumatic valve industry in China has a history of decades, by a simple pneumatic valve pneumatic valve to useful innovation, combined with years of experience, flange pneumatic ball valve constantly in improvement, pneumatic valve industry experienced many hardships and brilliance.
flange ball pneumatic valve is a kind of commonly used hardware products, pneumatic valve flange ball before assembly and assembly process also has a certain technical requirements, otherwise the assembly out of the pneumatic valve flange ball can't reflect its itself has the good performance, flange pneumatic ball valve in the assembly process what technical requirements?
flange ball pneumatic valve assembly before handling requirements:
, according to the processing requirements, some parts need to do polishing processing, surface can't be machining burrs, etc. ;
pneumatic valve, flanged ball all parts for degreasing process;
and degrease pickling passivation, after the completion of cleaning agent does not contain phosphorus;
, pickling passivation after rinse clean with water, there can be no drug residues, carbon steel parts leave out this step;
dry component with non-woven fabric, one by one, not the cable MAO retained components such as surface, or use a clean dry nitrogen;
, with non-woven fabric or precision filter analysis of pure alcohol to wipe components one by one, until no dirty color.
flange ball pneumatic valve assembly technical requirements:
, installation workshop must ensure clean, or clean up temporary area, for example with the new purchase of striped cloth or plastic film, such as, prevent dust during the installation process has entered.
and assembly workers must be dressed in a clean, pure cotton overalls, head Dai Chun cotton padded cap, hair can't leakage, foot wear clean shoes, hand wear plastic gloves, skim.
, erection tools must be clean before assembly to skim, ensure clean.
