style="text-indent:25px">真空閥門的不是實(shí)際意義上的管道外徑或內(nèi)徑，雖然其數(shù)值跟管道內(nèi)徑較為接近或相等，為了使管子、管件連接尺寸統(tǒng)一，采用公稱直徑（也稱公稱口徑、公稱通徑)。例如焊接鋼管按厚度可分為薄壁鋼管、普通鋼管和加厚鋼管。其公稱直徑不是外徑，也不是內(nèi)徑，而是近似普通鋼管內(nèi)徑的一個(gè)名義尺寸。每一公稱直徑，對應(yīng)一個(gè)外徑，其內(nèi)徑數(shù)值隨厚度不同而不同。公稱直徑可用公制表示，也可用英制表示。管路附件也用公稱直徑表示，意義同有縫管。公稱壓力：(Nominal pressure)，表示符號(hào)PN，在一定溫度下應(yīng)用時(shí)允許的比較大工作壓力。對碳鋼閥體的控制閥，指200℃以下應(yīng)用時(shí)允許的比較大工作壓力；對鑄鐵閥體，濟(jì)南滑閥式真空泵，指120℃以下應(yīng)用時(shí)允許的比較大工作壓力；對不銹鋼閥體的控制閥，指250℃以下應(yīng)用時(shí)允許的比較大工作壓力。當(dāng)工作溫度升高時(shí)，閥體的耐壓會(huì)降低。例如，公稱壓力為6，濟(jì)南滑閥式真空泵.4MPa（PN64）的碳鋼控制閥，用于300℃時(shí)的耐壓為5.2MPa，用400℃時(shí)的耐壓為4.1MPa，用于450℃時(shí)的耐壓為2.9MPa。因此，控制閥公稱壓力的確定不*要根據(jù)比較高工作壓力，濟(jì)南滑閥式真空泵，還需根據(jù)比較高工作溫度和材質(zhì)特性，而不**只需滿足公稱壓力大于工作壓力。手動(dòng)高真空球閥可以實(shí)現(xiàn)開關(guān)氣路，進(jìn)而改變氣流的流通路線。濟(jì)南滑閥式真空泵</p><div
