Briefly describes the work of cleaning the titanium valve before installation

Sunrui titanium valve parts before assembly must go through the following process:
1, according to process requirements, some parts need to do the polishing processing, surface can't be machining burrs, etc.;
2, all parts for degreasing process;
3, degrease pickling passivation, after the completion of cleaning agent does not contain phosphorus;
4, rinse clean with clean water after pickling passivation, there can be no drug residues, carbon steel parts leave out this step,;
5 parts with non-woven fabric, shot for dry, not cable MAO retained components surface, or use a clean dry nitrogen;
6, with non-woven fabric or precision filter analysis of pure alcohol to wipe components one by one, until no dirty color.

How electric titanium valve maintenance ?

1 , the electric Sunrui titanium valve should be kept dry and ventilated room , both ends of the path must be blocked.
2 , long-term storage of electric titanium valves should be checked regularly to remove dirt and oil processing surface coated with rust .
3 , after installation, should be regularly checked , the main inspection items :
( A ) the sealing surface wear.
( 2 ) the stem and stem nut trapezoidal thread wear.
( 3 ) failure of the filler is outdated , should be replaced if damaged .
( 4 ) After the overhaul of electric titanium valve assembly , seal performance test should be carried out .
The operation of the electric titanium valves, various valves should be complete, intact. Flange bolts and bracket indispensable thread should be intact , does not allow loosening. Hand tighten the nut on the wheel , if found loose should be tightened to avoid abrasion or lost connections handwheel and plate . Handwheel , if lost, are not allowed to use wrenches instead should be promptly installed for . Gland allowed to skew or no pretension gap . For vulnerable rain and snow, dust, sand and dirt contaminated environments electric valve , which stem to install protective cover. Scale electric valve should be kept complete, accurate and clear. Electric valve seals, caps, pneumatic accessories should be complete and intact . Insulation jacket should be no dents, cracks.
Allowed on the operation of the electric titanium valves beat , stand or support weight ; particularly non-metallic titanium valves and cast iron electric motor titanium valves , but also to prohibit .
