由計算出的安全閥的定壓值決定彈簧或杠桿的調(diào)壓范圍，根據(jù)使用介質(zhì)決定安全閥的材料和結(jié)構(gòu)形式，根據(jù)安全閥的排放量計算出安全閥的噴嘴截面積或噴嘴直徑，以選取安全閥型號和個數(shù)。彈簧直接載荷式安全閥的工作壓力等級如表2-5所示，共有五種工作壓力級。選擇時，除注明產(chǎn)品型號、名稱、介質(zhì)、溫度外，還應(yīng)注明彈簧的壓力級別。表2-5彈簧安全閥工作壓力級公稱壓力PN/MPa工作壓力/MPaρⅠρⅡρⅢρⅣρⅤ＞～＞～＞16～20＞～＞～＞20～25＞～＞～＞～＞～＞～＞～＞～＞22～25＞～＞～＞～＞～＞～＞～＞10～13＞25～29＞～＞～＞～＞～＞～＞～10＞13～16＞29～32安全閥的進口和出口分別處于高壓和低壓兩側(cè)，所以連接法蘭也相應(yīng)采用不同的壓力等級，如表2-6所示。表2-6安全閥進出口法蘭壓力級MPa安全閥公稱壓力進口法蘭壓力級出口法蘭壓力級當(dāng)介質(zhì)經(jīng)由安全閥排放時，其壓力降低，體積膨脹，流速增加，故安全閥的出口通徑大于進口通徑。對于微啟式安全閥，其出口通徑可等于進口通徑，這是因其排量小，又常用于液體介質(zhì)。而全啟式安全閥的排量大，多用于氣體介質(zhì)，故其出口通徑一般比公稱通徑大一級。進出口通徑按表2-7選用。烏魯木齊柱塞閥生產(chǎn)廠家。烏魯木齊電動球閥閥門哪家好</p><p
