style="text-indent:25px">需要知道的是封頭在使用的時(shí)候是和我們的錐形封頭不一樣的，這種封頭是屬于小型不銹鋼封頭安裝的時(shí)候有很大的區(qū)別。不銹鋼封頭的直徑大小跨度十分的大，在安裝中型或者是大型不銹鋼封頭的時(shí)候一般使用的都是冷安裝的方式，也是直接的使用一些固化的安裝方式，但是小型不銹鋼封頭之上使用這種安裝技術(shù)是不切實(shí)際的，因?yàn)楹芏嗟臅r(shí)候我們的小型不銹鋼封頭是需要多次反復(fù)拆裝的，這樣我們需要另外的一種安裝方式。螺紋安裝方式對(duì)于小型不銹鋼封頭來(lái)說(shuō)是一個(gè)不錯(cuò)的選擇。封頭組成以閥桿位移為測(cè)量信號(hào)，以控制器輸出為設(shè)定信號(hào)的反饋控制系統(tǒng)。</p><div
