公稱壓力：按質(zhì)量碳素鋼材質(zhì)和介質(zhì)參數(shù)，由表1-3查得：閥門公稱壓力為PN=16MPa。密封面材料：根據(jù)閥門公稱壓力和介質(zhì)溫度，按表2-3b可選用不銹鋼或硬質(zhì)合金鋼。驅(qū)動(dòng)方式：本例未提特殊要求，可采用手輪驅(qū)動(dòng)。連接形式：法蘭連接。公稱通徑：根據(jù)介質(zhì)參數(shù)，管材可選用50號(hào)質(zhì)量碳素鋼無縫鋼管，按管子內(nèi)徑107mm，公稱壓力℃溫度下的許用應(yīng)力，管子壁厚選定為14mm，則管子計(jì)算外徑為DW=107+2×14=135mm，采用外徑為140mm，此時(shí)公稱通徑為DN=125mm，新疆?dāng)?shù)字鎖定平衡閥價(jià)格。閥門的公稱直徑應(yīng)與管子相同。閥門的類型與型號(hào)：油品管道應(yīng)選用閘閥。根據(jù)閥門參數(shù)表的參數(shù)，當(dāng)PN=16MPa時(shí)，新疆?dāng)?shù)字鎖定平衡閥價(jià)格，截止閥**大公稱通徑為40mm，新疆?dāng)?shù)字鎖定平衡閥價(jià)格，而同樣壓力等級(jí)下閘閥的**大公稱通徑為200mm，因此也應(yīng)選用閘閥。按閘閥參數(shù)表，在PN16MPa下的碳鋼手輪法蘭閘閥型號(hào)有Z41H-160和Z41Y-160兩種。但前者的**大公稱通徑為40mm，而后者的**大公稱通徑為200mm，故應(yīng)選用Z41Y-160型閘閥，其閥門密封面為硬質(zhì)合金。所選用的呋喃全稱為：明桿楔式單閘板閘閥（Z41Y-160DN125）。八、自動(dòng)閥門的選用返回頁首自動(dòng)閥門的選用與一般閥門一樣，除要考慮經(jīng)濟(jì)合理性、經(jīng)久耐用外，還要求自動(dòng)閥門的動(dòng)作靈敏、可靠、調(diào)節(jié)準(zhǔn)確等性能。烏魯木齊排污閥生產(chǎn)廠家。新疆?dāng)?shù)字鎖定平衡閥價(jià)格</p><div
