style="text-indent:25px">標(biāo)準(zhǔn)橢圓封頭作為壓力容器中比較重要的受壓元件之一，在選用的時候，我們通常是根據(jù)需要的標(biāo)準(zhǔn)進行選擇，但很多時候有些工作人員在標(biāo)準(zhǔn)橢圓封頭加工困難的情況下，采用旋壓橢圓封頭進行替代，這種做法是不可取的。一方面是因為標(biāo)準(zhǔn)橢圓封頭與旋壓橢圓封頭在制造的方法上是不同的，因此使用時不能進行有效替代。標(biāo)準(zhǔn)橢圓封頭的形狀是由沖壓模具來決定的，因此只要將所中的沖壓模具按照標(biāo)準(zhǔn)的橢圓封頭形狀進行加工可以了，所沖壓封頭是標(biāo)準(zhǔn)的橢圓封頭。封頭可以調(diào)節(jié)的參數(shù)還有零位彈簧的彈性系數(shù)和反饋杠桿的有效長度。</p><div
