Theoretical Analysis and Experiment Study of Ferrule Needle Valve

Abstract

针阀是现代工业领域重要的执行或调节元件之一,广泛应用于石油、化工、市政、电力等关系国计民生的重要领域。卡套针阀是针阀的一种,具有较高的流量调节精度、较好的流量调节线性度,由于采用了卡套式接头,卡套针阀还具有优秀的接头快速密封性能,具有广阔的市场前景和研究价值。本文主要工作如下: (1)在充分研究了卡套针阀工作原理的基础上,根据阀门设计手册、《MSSSP-99仪表阀门》等技术标准,对卡套针阀进行了总体结构设计,用Solidworks建立了相应的三维模型;计算校核了阀体壁厚和阀杆强度,并运用有限元分析软件Patran/Nastran进行了有限元分析验证;分别研究、推导了金属和填料密封原理,并求解...The needle valve is an important executive component in modern industry, it’s widely used in petroleum industry, chemical industry, municipal construction, electric system and some other important areas. Ferrule needle valve is one branch of needle valve which with higher flow regulation accuracy, better flow regulation linearity. As a result of using bite type tube fittings, the interfaces of fer...学位:工学硕士院系专业:物理与机电工程学院_机械工程学号:1992010115273
