Valve parts in the assembly before the deal must goControl Valves through the following procedure: 1) According to the processing requirements, some parts need to do polishing, the surface can not have processing spikes, etc.; Two) for degreasing of all parts; 3) after completion of acid skim Cryogenic Valves passivation (detergent phosphate); 4) after acid passivation rinse with pure water, no drug residues (carbon steel parts omitted this step); 5) one by one with a cloth to dry the parts can not be wired hair surface components Forged Steel Valves such as retention, or be dried with clean nitrogen; 6) filter paper stained with a non-woven or precision parts and components analytically pure alcohol wipe on one by one, until there is no dirty color. 2, assembly required Cleaned parts must be kept under seal for installation. Requirements of the installation process is as follows: 1) Install the workshop to ensure clean, or build a temporary clean area (for example, purchasedBellow Seal Valves with a new color cloth or plastic film, etc.) to prevent dust entering the installation process. 2) assembly workers must be wearing clean cotton clothing, wearing cotton cap, hair should not leak, be wearing clean, shoes, wearing plastic gloves (skim). 3) assembly tools must be cleaned before assembly to skim,Instrument Valves to ensure cleanliness. 3, other requirements 1) the completion of the valve assembly with nitrogen purge at least 1 min. 2) leak test must be used pure nitrogen.

译文:关于脱脂阀门的步骤要求以及检验
阀门的零部件在组装前必须经过以下过程处理:   1)根据加工要求,部分零部件蝶阀 需要做抛光处理,表面不能有加工毛刺等;   2)所有零部件进行脱脂处理;   3)脱脂完成后进行酸洗钝化(清洗剂不含磷);   4)酸洗针型阀 钝化后用纯净水冲洗干净,不能有药剂残留(碳钢部件省去此步骤);   5)逐个零部件用无纺布进行擦干,不能有线毛等呼吸阀 留存部件表面,或者用洁净的氮气进行吹干;   6)用无纺布或者精密滤纸沾分析纯酒精对逐个零部件进行擦拭,直至没有脏色。   2、 装配要求   清洗干净的部件必须密封保存,以供安装。对安装过程要求如下:   1)安装车间必须保证洁净,或者搭建临时的洁净区域(例如疏水阀 用新购的彩条布或者塑料薄膜等),防止在安装过程中有灰尘进入。   2)装配工人必须身着洁净的纯棉工作服,头戴纯棉帽,头发隔膜阀 不能外漏,脚穿干净鞋子,手戴塑胶手套(脱脂)。   3)装配用工具必须在装柱塞阀 配前进行脱脂清洗,保证洁净。   3、 其他要求   1)装配完成的旋塞阀 阀门用氮气至少吹扫1分钟。   2)气密试验必须是用纯净的氮气。
