style="text-indent:25px">封頭現(xiàn)在在比較多地方都有用到，有時，內(nèi)行人也不容易區(qū)分橢圓封頭和碟形封頭，這主要是因為兩種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好一些，這是因為相同直徑的情況下，橢圓封頭會比蝶形封頭更深一點，所以制造難度上就比碟形的稍大，而且成本會更高，雖然容積上的差異比較小，但是橢圓封頭受力會更均勻一些。 2、形狀不同。其實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)，所以是一項開創(chuàng)性比較好的封頭產(chǎn)品。封頭可以克服閥桿的摩擦力，去除不平衡的影響。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">封頭拋光時有哪些要求？在鍋爐和一些壓力容器上，為了保證工作的密封性，通常需要封頭進(jìn)行堵塞，而對于封頭來說，為了讓其與安裝的部件相一致，所以有時會需要做一些拋光處理。在拋光時對封頭的形狀也是有要求的，如不銹鋼橢圓形封頭、蝶形封頭、錐形封頭等可進(jìn)行內(nèi)外拋光，效果非常好。那么封頭拋光的要求有哪些呢，下面就一起來了解下。封頭拋光通常會用專門的拋光機(jī)，這些拋光機(jī)的自動化設(shè)計非常高，在進(jìn)行工作的時候，只要把拋光的工件等放在相應(yīng)的位置上，然后在工作臺上作固定處理，就可以開始進(jìn)行拋光了。當(dāng)然拋光的時間需要做下合理的設(shè)定，這樣工作就會變得更簡單。需要注意的是，封頭拋光分為精拋和細(xì)拋兩種方式，做粗拋處理的封頭可以所表層的損傷及時去除，拋光速率會比較高；而使用精拋技術(shù)的封頭，不僅能去掉封頭表層的損傷，還能讓拋光損傷減少到較低。它具有以往的材料都不具有的優(yōu)點，能適用在各個地方，并且使用年限長，質(zhì)量過硬，不存在維修問題。封頭功能越來越多樣化，使得它的發(fā)展也是越來越壯大，在各大機(jī)械行業(yè)中頻繁使用到的封口材料。它的功能得到了比較大的提升，在抗壓能力上它的性能優(yōu)良比較大程度的改變，密封性也比原來更加優(yōu)良。江蘇管帽封頭生產(chǎn)廠家直銷</p><p
