1、本科毕业设计题目低温截止阀的设计学院工业制造学院机械设计制造及其自动化学生姓名学号年级11指导教师职称讲师2015年3月28日低温截止阀的设计专业:机械设计制造及其自动化学号:姓名:指导老师:摘要:本课题來源于当今社会液压元件的创新和更新换代基础Z上,通过设计出低温截上阀,从而来满足当今社会液压元件更新换代能力不足的缺陷。低温截止阀是能够在低温丄况卜•使用的截止阀,通常把丄作温度低于-40°C的截止阀称为低温截止阀。低温截止阀是石油化工、空气分离、天然气等工业不可缺少的重要设备0—,其质量的优劣决定着
2、能否安全、经济、持续地生产。随着现代科技的发展,低温截止阀的用途越来越广,需求也越來越大。本文运用大学所学的知识,了解低温截止阀的工作原理,在此基础上,设计一款低温截止阀。该低温截止阀的丄作介质为12MPa的液压油,它是用来改变管路断而和介质流动方向、控制输送介质的压力、流量、温度的一种装直。通过查找相关料,了解低温截止阀的内部结构和工作原理,构建了低温截止阀组成结构的总的指导思想,从而得出了该低温截止阀的优点是高效,经济,并且截止效果好,运行平稳的结论。关键词:低温截止阀;液压元件;截止阀;装置Th
