style="text-indent:25px">從受力和制造兩方面比較半球形、橢圓形、碟形、錐殼和平蓋封頭的特點(diǎn)，并說(shuō)明其主要應(yīng)用場(chǎng)合。(1)半球形封頭：在均勻內(nèi)壓作用下，薄壁球形容器的薄膜應(yīng)力為相同直徑圓筒體的一半。但缺點(diǎn)是深度大，直徑小時(shí)，整體沖壓困難，大直徑采用分瓣沖壓其拼焊工作量也較大。半球形封頭常用在高壓容器上。(2)橢圓形封頭：橢球部分經(jīng)線曲率變化平滑連續(xù)，故應(yīng)力分布比較均勻，且橢圓形封頭深度較半球形封頭小得多，易于沖壓成型，是目前中、低壓容器中應(yīng)用較多的封頭之一。(3)碟形封頭：是一不連續(xù)曲面，在經(jīng)線曲率半徑突變的兩個(gè)曲面連接處，由于曲率的較大變化而存在著較大邊緣彎曲應(yīng)力。該邊緣彎曲應(yīng)力與薄膜應(yīng)力疊加，使該部位的應(yīng)力遠(yuǎn)遠(yuǎn)高于其它部位，故受力狀況不佳。但過(guò)渡環(huán)殼的存在降低了封頭的深度，方便了成型加工，且壓制碟形封頭的鋼模加工簡(jiǎn)單，使碟形封頭的應(yīng)用范圍較為普遍。(4)錐殼：結(jié)構(gòu)不連續(xù)，錐殼的應(yīng)力分布并不理想，但其特殊的結(jié)構(gòu)形式有利于固體顆粒和懸浮或粘稠液體的排放，可作為不同直徑圓筒體的中間過(guò)渡段，因而在中、低壓容器中使用較為普遍。蘇州碳鋼封頭制造廠盡管封頭拼接是經(jīng)過(guò)100％測(cè)試的，但合格級(jí)別卻有所不同，并且隨設(shè)備外殼而變化。</p><div

style="text-indent:25px">如何防止球形封頭變形？球形封頭中，根據(jù)壓機(jī)立柱間距和壓模尺寸及鋼板尺寸，選定頂圓需拼焊的板寬和拼焊塊數(shù)。盡可能采用壓鼓。直徑7.5m球形封頂圓取直徑6.2m，3塊板拼焊后壓鼓，然后車環(huán)縫坡口；直徑6.5m球形封頭頂圓取直徑5.36m，2塊板拼焊后壓鼓，然后車環(huán)縫坡口。直徑12m球形封頭頂圓取直徑lOm，直徑較大，由5塊板拼接，先分別壓形，然后切割研配向心、徑向縱縫坡口。為了防止自由變形，先制2個(gè)圓胎，檢測(cè)研配都可在此胎上進(jìn)行。球形封頭是以球殼的球冠部分所形成的封頭，有半球形封頭和無(wú)折邊球性封頭兩類。它在同樣容積下表面積較小，相同承壓條件下需要的厚度較薄，從節(jié)省材料和強(qiáng)度上看，是較合理的。另外，球形封頭具有鍛打精良，表面光滑，耐酸耐堿耐高溫，外形美觀，質(zhì)感性能強(qiáng)等特點(diǎn)。此類封頭為一塊深度比較淺的球面體(球冠)。其結(jié)構(gòu)見(jiàn)圖。它結(jié)構(gòu)簡(jiǎn)單，深度淺，易加_百一制造，成本低。但它與筒體連接處存在著明顯的形狀突變，導(dǎo)致產(chǎn)生比較高的局部應(yīng)力，故受力狀況極差，所以這類封頭一般只能用于直徑比較小，壓力較低的容器。封頭在工作時(shí)可以保證調(diào)節(jié)閥的正確定位。</p><div
