style="text-indent:25px">封頭屬壓力容器中鍋爐部件的一種。通常是在壓力容器的兩端使用的。再有就是在管道的末端做封堵之用的一種焊接管件產(chǎn)品。有比較多種的形式。接下來我為您介紹一下山東封頭的標(biāo)準(zhǔn)。我國現(xiàn)有的封頭標(biāo)準(zhǔn)，是按結(jié)構(gòu)型式(橢圓形、碟形、錐形)、成形方式(沖壓、旋壓)的不同，而分別制訂的，這不*造成不同標(biāo)準(zhǔn)封頭質(zhì)量要求不完全一致的不合理現(xiàn)象，同時(shí)也給標(biāo)準(zhǔn)封頭的選用、標(biāo)準(zhǔn)的修訂帶來某些困難。1、以往的封頭標(biāo)。準(zhǔn)都是*與GB150《鋼制壓力容器》配套的，即只考慮了按規(guī)則設(shè)計(jì)的封頭的制造、檢驗(yàn)與驗(yàn)收要求，而我國早在1995年就完成GB150與JB4732了壓力容器基礎(chǔ)標(biāo)準(zhǔn)的雙軌制(與《鋼制壓力容器分析設(shè)計(jì)標(biāo)準(zhǔn)》)，缺少與分析設(shè)計(jì)相配套的封頭標(biāo)準(zhǔn)，不能不說是我國壓力容器標(biāo)準(zhǔn)化工作的一大缺憾；2、GB150屬強(qiáng)制性標(biāo)準(zhǔn)，而根據(jù)GB150編制并與之配套的封頭標(biāo)準(zhǔn)卻是指導(dǎo)(推薦)性的，這顯然是不合理的，也難以保證封頭這一重要受壓元件的質(zhì)量。</p><p

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)，并說明其主要應(yīng)用場合。(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渡段，因而在中、低壓容器中使用較為普遍。連云港原水處理設(shè)備封頭報(bào)價(jià)</p><p
