DN1100煤气水封铸钢闸阀设计(含CAD零件图装配图)(论文说明书17000字,外文翻译,CAD图6张)
摘 要
本论文课题是设计闸阀的结构与工艺。闸阀主要由阀体、阀盖、闸板、阀杆等装置组成，其结构在阀体内类似闸阀一样的板状物与无相配的两阀座(或单阀座)之间垂直于流体移动，从而打开或切断流道。用它做启闭使用，并在全开时有整个流道直通的作用。闸阀适用范围广泛，主要应用于石油、化工、电力、医药、火力等行业。
本文是针对DN1100煤气水封闸阀的设计展开阐述。该闸阀设计为法兰连接形式的软密封结构，阀体与阀座采用螺纹阀座，阀盖与支架采用分体结构。闸阀结构设计的基;本内容为对闸阀标准的了解、阀体壁厚计算与校核、阀体尺寸的确定、密封比压计算、总转矩计算、阀杆强度校核等;闸阀工艺设计主要着重对闸板、阀体、阀座、阀盖、阀杆等主要零件的制造加工工艺规程编制。

Abstract
The subject of this paper is to design the structure and technology of gatevalve.Gate valve is mainly composed of valve body,valve cover,gate plate, stem and other devices.Its structure moves perpendicular to the fluid between aplate-like object similar to gate valve and two valve seats(or single valve seat)with out matching,thus opening or cutting off the flow passage.It is used for opening and closing,and has the function of straight-through of the whole flow passage when fully opened.Gate valves are widely use dinpetroleum,chemical in dustry,electric power,medicine,fire and other in dustries.This article focuses on the design of DN1000 gas water seal gate valve.The gate valve is designed as a soft sealing structure in the form off langeconnection.The valve body and valve seat a dopt threaded valve seat,and the valve cover and bracket a dopt split structure.Foundation of gate valve structural design;This contentis the under standing of gate valve standard,calculation and check of valve body wall thickness,determination of valve body size,calculation of sealing specific pressure,calculation of to taltorque,check of valve stem strength,etc.The gate valve process design mainly focuses on the preparation of manufacturing processs pecifications for the main partssuchas gate plate,valvebody,valveseat,valvecover,valvestem,etc.Keywords:gate valve;Structure and technology;Sealing;Sealing pressureratio.
