球阀选型适用原则

原文：
球阀选型适用原则： 1、石油、天然气的输送主管线、需要清扫管线的，又需埋设在地下的，选用全通径、全焊接结构的球阀；埋设在地上的，选择全通径焊接连接或法兰连接的球阀；支管，选用法兰连接、焊接连接，全通经或缩径的球阀。
2、成品油的输送管线和贮存设备，选用法兰连接的球阀。
3、城市煤气和天然气的管路上，选用法兰连接和内螺纹连接的浮动球阀。
4、冶金系统中的氧气管路系统中，宜选用经过严格脱脂处理，法兰连接的固定球球阀。
5、低温介质的管路系统和装置上，宜选用加上阀盖的低温球阀。
6、炼油装置的催化裂化装置的管路系统上，可选用升降杆式球阀。
7、化工系统的酸碱等腐蚀性介质的装置和管路系统中，宜选用奥氏体不锈钢制造的、聚四氟乙烯为阀座密封圈的全不锈钢球阀。
8、需要进行流量调节时，可选用蜗轮蜗杆传动的、气动或电动的带V形开口的调节球阀。
9、冶金系统、电力系统、石化装置、城市供热系统中的高温介质的管路系统或装置上，可选用金属对金属密封球阀。

译文： Ball valve selection principles： 1、Transport of petroleum and natural gas mains, needs cleaning the pipeline, and to be buried in the ground, selection of full size, full welded ball valve structure; Buried in the ground, choose the full size welded ball valve connection or flange connection; Branch, choose flange connection, welding connection, the menstruation or reducing valves.
2、Product oil pipeline and storage equipment, use flange connection of the ball.
3、City of coal gas and natural gas pipeline, choose floating ball valve flange connection and internal thread connection.
4、Oxygen in the pipeline system in metallurgical system, appropriate chooses strict degreasing process, flange connection of the fixed ball ball valve.
5、Low temperature medium pipeline system and device, appropriate chooses and cryogenic ball valve bonnet. 6、Piping system on oil refining equipment of catalytic cracking unit, can choose lifting lever type ball valve.
7、Chemical system in acid and alkali corrosive medium, such as equipment and piping system, appropriate chooses austenitic stainless steel, teflon for stainless steel ball valve seat sealing.
8、The need for flow control, can choose of worm gear and worm drive, pneumatic or electric regulating ball valve with v-shaped opening.
9、Metallurgical system, electric power system, petrochemical plant, city heating system in high temperature medium pipeline system or device, can choose a metal to metal sealed ball valve.

不锈钢球阀组装前和安装所需哪些步骤

原文：
不锈钢球阀在组装前与组装后都要严格地按照要求的步骤来完成，本文主要介绍不锈钢球阀的零部件在组装前必须经过的处理过程，具体如下：

（1）根据加工要求，部分零部件需要做抛光处理，表面不能有加工毛刺等;
2)所有零部件进行脱脂处理;
3)不锈钢球阀脱脂完成后进行酸洗钝化(清洗剂不含磷);
4)酸洗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。

不锈钢球阀安装的其他要求：
1)装配完成的不锈钢球阀用氮气至少吹扫1分钟;
2)气密试验必须是用纯净的氮气;
3)气密试验合格后进行包封，用干净聚乙烯帽密封，聚乙烯帽使用前应用有机溶剂浸泡，擦拭干净;
4)然后用真空袋进行密封;
5)zui后装箱;
6)运输过程中要采取措施保证包封不破损。不锈钢球阀组装前和安装所需哪些步骤。

译文：
Stainless steel ball valve should be strictly in accordance with the requirements of the steps to complete before assembly and assembly, this paper mainly introduces the process of stainless steel ball valve parts must be passed before the assembly, as follows:
1) according to the requirements of the processing, some parts need to be polished, the surface can not have machining burrs;
2) all parts degreasing;
3) stainless steel ball skimmed after pickling and passivation (detergent without phosphorus);
4) pickling passivation with clean water rinse clean, no residue (carbon steel parts omit this step);
5) by parts with non-woven wipe, surface not wired hair etc. retained components, or with a clean dry nitrogen;
6) with non-woven fabrics or precision filter paper with analytical pure alcohol by parts of wiping, until there is no dirty color. Other requirements of stainless steel ball valve installation:
1) stainless steel ball valve assembly with nitrogen purge completed at least 1 minutes;
2) the test must be airtight with pure nitrogen;
3) after passing the test gas tight encapsulation, seal cap with a clean polyethylene, polyethylene cap soaked in organic solvent before use, wipe clean;
4) and then vacuum sealed;
5) finally packing;
6) transport in the process to take measures to ensure that the encapsulation is not broken.
