前言

阀门是流体管路的控制装置，其基本功能是接通或切断管路介质的流通，改变介质的流动方向，调节介质的压力和流量，保护管路的设备的正常运行。

随着现代工业的不断发展，阀门需求量不断增长，一幢现代高楼需要大量的阀门；一个现代化的石油化工装置就需要上万只各式各样的阀门。但往往由于制造、使用选型、维修不当，发生跑、冒、滴、漏现象，由此引起火焰、爆炸、中毒、烫伤事故，或者造成产品质量低劣，能耗提高，设备腐蚀，物耗提高，环境污染，甚至造成停产等事故，已屡见不鲜。因此，人们希望获得高质量的阀门，同时也要求提高阀门的使用，维修水平，这时对从事阀门操作人员，维修人员以及工程技术人员，提出新的要求，除了要精心设计、合理选用、正确操作阀门之外，还要及时维护、修理阀门，使阀门的“跑、冒、滴、漏”及各类事故降到最低限度。阀门选择原则有以下三个方面：一、满足使用性能

为了满足使用性能，就要根据阀门的工作条件即介质的 …… 此处隐藏：3085字，全部文档内容请下载后查看。喜欢就下载吧 ……
