不銹鋼氣動三通球閥
  Stainless steel ball valve before the installation of the preparation work is divided into the following steps:
 
  1,cleaning steps:
 
  1)according to the processing requirements,stainless steel valve parts need to do polishing treatment,the surface can not have machining burr,etc.;
 
  2)all spare parts for fat treatment;
 
  3)after completion of degreasing pickling and passivation(detergent without phosphorus);
 
  4)after pickling passivation with pure water rinse clean,can not have pharmaceutical residues(carbon steel parts to save this step);
 
  5)parts one by one surface can not be wired to dry non-woven fabrics,wool and other retained components,or with clean dry nitrogen;
 
  6)use non-woven fabrics or precision filter paper dip analysis of pure alcohol to wipe the parts one by one,until there is no dirty color.
 
  2,assembly requirements
 
  The cleaned parts must be kept in a sealed and kept for installation.The installation process is as follows:
 
  1)installation workshop to ensure clean,or build a temporary clean area(for example,the purchase of new color cloth or plastic film,etc.)to prevent dust entering the installation process.
 
  2)assembly workers must wear clean cotton clothing,wearing a cotton cap,hair can not leak,wearing a clean shoes,wearing plastic gloves(skim).
 
  3)assembly tools must be cleaned before assembly to ensure cleanliness.
 
  3.Other requirements
 
  1)to complete the valve with nitrogen purge at least 1 minutes.
 
  2)air tightness test must be pure nitrogen.
 
  3)airtight test after passing the bag sealing,with a clean polyethylene cap seal,the use of polyethylene cap before the use of organic solvent immersion,wipe clean.
 
  4)and then sealed with vacuum bag.
 
  5)the final packing.
 
  氣動不銹鋼三通球閥安裝前的準備工作分為以下幾個步驟:
 
  1,清洗步驟:
 
  1)根據加工要求,不銹鋼閥門零件需要做拋光處理,表面不能有加工毛刺等;
 
  2)所有脂肪處理備件;
 
  3)脫脂酸洗和鈍化(無磷洗滌劑)完成后;
 
  4)酸洗鈍化后用純水沖洗干凈,不能有藥物殘留(碳鋼零件節省這一步);
 
  5)部件一個接一個表面不能接到干燥的無紡布,羊毛和其他保留的部件,或用干凈的干燥氮氣;
 
  6)使用無紡布或精密濾紙浸泡分析純酒精,逐一擦拭部件,直到沒有臟的顏色。
 
  2,裝配要求
 
  清潔的部件必須保持密封,并保持安裝。安裝過程如下:
 
  1)安裝車間確保清潔,或建立臨時清潔區(例如購買新顏色布或塑料膜等),防止灰塵進入安裝過程。
 
  2)裝配工人必須穿干凈的棉衣,戴上棉帽,頭發不能泄漏,穿干凈的鞋,戴上塑料手套(脫脂)。
 
  3)組裝工具必須在組裝前進行清潔,以確保清潔度。
 
  3.其他要求
 
  1)用氮氣吹掃完成閥至少1分鐘。
 
  2)氣密性試驗必須是純氮氣。
 
  3)密封試驗后通過袋密封,用干凈的聚乙烯蓋密封,使用聚乙烯蓋前使用有機溶劑浸泡,擦拭干凈。
 
  4),然后用真空袋密封。
 
  5)最終包裝。
