摘要/Abstract

摘要： 换热器管箱球膜密封是一种高温高压无泄漏的绿色环保新结构，针对该新结构与隔板之间不能采取传统强制密封的问题，对小直径管箱隔板提出了局部结构和整体结构两种设计形式，并通过案例分别对四边简支、对边简支和半椭圆固支、三边固支4种边界条件的隔板进行了强度设计计算，介绍了对固支边界条件隔板进行强度校核的计算式。对大直径收口管箱提出了分片组合的隔板结构。

Abstract: Spherical shape diaphragm of heat exchanger tube channel is a new structure of green and environment protection as its no leakage under high temperature and high pressure. Part structures and whole structures were designed for baffle plate of small diameter tube-channel, because spherical shape diaphragm new structure can not sealing with baffle plate by force. Strength design of baffle plate was calculated which of four kind boundary conditions, including four sides simple support, symmetric sides simple support and half-ellipse side fixed support or four sides fixed support. Formulas were introduced that used to check the strength of baffle plate fixed support sides. Combined baffle by parts were designed for baffle plate of large diameter tube-channel.

Key words: seal, baffle plate, spherical shape insulate diaphragm, strength design, optimal design, mechanical properties
