Stainless steel ball pneumatic valve degreasing steps

stainless steel ball pneumatic valve before assembly and after assembly should be strictly in accordance with the requirements of the steps to complete, this paper mainly introduces the stainless steel ball, must pass before pneumatic valve parts in the assembly process, specific as follows:

according to process requirements, some parts need to do polishing processing, surface can't be machining burrs, etc. ;

all parts for degreasing process;

stainless steel ball pneumatic valve degrease pickling passivation after completing ( Detergent does not contain phosphorus;

with pure water rinse after pickling passivation, there can be no drug residues ( Carbon steel parts leave out this step;

one dry parts with non-woven fabric, 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.

stainless steel ball pneumatic valve installation of other requirements:

fabricated stainless steel ball of the pneumatic valve with nitrogen purging at least minutes;

air test must be pure nitrogen;

air test qualified junior stuff, with a clean PE cap seal, polyethylene cap before using organic solvent soak, wipe clean;

then use sealed vacuum bag;

the final packing;

in the process of transportation to take measures to ensure the coating is not damaged.
