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。封頭上一般有開孔，標(biāo)準(zhǔn)的橢圓封頭的計(jì)算厚度和筒體基本一但是考慮到開孔補(bǔ)強(qiáng)的問題就會(huì)增加厚度。</p><div
