style="text-indent:25px">封頭現(xiàn)在在比較多地方都有用到，有時(shí)，內(nèi)行人也不容易區(qū)分橢圓封頭和碟形封頭，這主要是因?yàn)閮煞N封頭從外觀上看還是非常相似的，下面不銹鋼封頭廠家來給大家介紹一下蝶形封頭和橢圓形封頭的區(qū)別是什么。 1、受力不同。橢圓封頭的受力能力上相比來說會(huì)好一些，這是因?yàn)橄嗤睆降那闆r下，橢圓封頭會(huì)比蝶形封頭更深一點(diǎn)，所以制造難度上就比碟形的稍大，而且成本會(huì)更高，雖然容積上的差異比較小，但是橢圓封頭受力會(huì)更均勻一些。 2、形狀不同。其實(shí)整體上來說兩者形狀區(qū)別不大，不過橢圓封頭是吸取了半球形封頭受力好和碟形封頭深度淺的優(yōu)點(diǎn)結(jié)合制造出來的，部分經(jīng)線曲率平滑連續(xù)，所以是一項(xiàng)開創(chuàng)性比較好的封頭產(chǎn)品。</p><p style="text-indent:25px">影響封頭較小厚度的因素有哪些？1、剛度的影響：封頭在承受壓力的同時(shí)本身應(yīng)具備一定的剛度，以免發(fā)生變形破壞。因此，GB150規(guī)定，對碳素鋼、低合金鋼制容器不包括腐蝕裕量的較小厚度應(yīng)不小于3mm；對高合金鋼制容器不包括腐蝕裕量的較小厚度不小于2mm。2、壓力載荷的影響：封頭是承受一定壓力的受壓元件，首先必須滿足的條件是壓力載荷，無論承受內(nèi)壓或者外壓載荷的封頭都可通過GB150第3章有關(guān)計(jì)算公式得到封頭計(jì)算厚度，其中，計(jì)算厚度+腐蝕裕量=設(shè)計(jì)厚度，這個(gè)設(shè)計(jì)厚度是單從壓力載荷方面得到的封頭需要的較小厚度。3、內(nèi)壓失穩(wěn)的影響：內(nèi)壓作用下，標(biāo)準(zhǔn)橢圓封頭的應(yīng)力分布如圖1。由應(yīng)力分布圖可以看出，在封頭底邊處產(chǎn)生周向壓縮應(yīng)力，此處封頭容易發(fā)生周向失穩(wěn)。為防止橢圓封頭在內(nèi)壓作用下失穩(wěn)，GB150規(guī)定，對于Di/2hi≤2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.15%，對于Di/2hi＞2的橢圓形封頭的有效厚度應(yīng)不小于封頭內(nèi)直徑的0.30%。上述雖然限制的是有效厚度，但其實(shí)也間接限制了封頭成形的較小厚度。球形封頭的計(jì)算厚度是相同條件下筒體計(jì)算厚度的一半。</p><div

style="text-indent:25px">壓力容器用封頭有哪些？一般來說壓力容器用封頭主要是按照封頭的形狀來進(jìn)行區(qū)分的，比較常見的有球形封頭、圓形封頭、橢圓形封頭、蝶形封頭。這些封頭根據(jù)需求不同，會(huì)進(jìn)行不同的選擇。這主要是因?yàn)閹缀涡螤詈统叽绲母淖?，就?huì)影響內(nèi)壓殼受壓力的變化，如果說應(yīng)力不能在可控范圍內(nèi)的話，就會(huì)影響容器的整體承載能力，甚至有的部位就會(huì)成為設(shè)備的破壞源，所以多關(guān)注封頭的要求還是比較重要的。除了形狀之外，由于封頭要時(shí)時(shí)刻刻受到壓力，所以做工上的要求也比較高，尤其是在壓力容器封頭上的接管，它的結(jié)構(gòu)也是非常復(fù)雜的，開孔的大小、位置以及受力的情況經(jīng)常會(huì)超出常規(guī)的設(shè)計(jì)范圍，所以要引入具體的分析設(shè)計(jì)，這樣才能保證平安的使用。球冠形封頭廠</p><p
