流阻小的閥門，能源消耗少。對低壓力、大流量的水、空氣等介質(zhì)，選用大口徑閘閥和蝶閥比較合理。蝶閥可作截斷用，又能作節(jié)流用。3.安全可靠性一般水蒸氣管道上可采用+球墨鑄鐵閥門和鑄鋼閥門。但在室外蒸汽管道上，若停止供氣，水易結(jié)冰而使閥門破裂，特別是在我國北方。因此，宜采用鑄鋼或鍛鋼閥門，同時要做好閥門的防凍保溫工作。乙炔類易燃易爆的介質(zhì)，對密封性要求高。壓力在，應(yīng)采用隔膜閥，但不宜用在真空設(shè)備的管道上。對危害性很大的放射性介質(zhì)和劇毒介質(zhì)，應(yīng)采用波紋管結(jié)構(gòu)的閥門，以防介質(zhì)從填料函中泄漏。對于帶有驅(qū)動裝置（電動、液動、氣動）的閥門，除要求驅(qū)動裝置安全可靠外，還要根據(jù)工況條件的不同，選用相應(yīng)的驅(qū)動裝置。例如，在需要防火的工況下，應(yīng)選用液動、氣動裝置的閥門；必須選用電動裝置的閥門時，其電動裝置應(yīng)為防爆型，以避免電弧引起火災(zāi)。4.操作和維修方便對于大型閥門和處于高空、高溫、高壓、危險、遠距離的閥門，應(yīng)選用齒輪傳動、鏈條傳動或帶有電動裝置、氣動裝置、液動裝置的閥門。在操作空間受到限制的場合，不宜處于明桿閘閥，以選用暗桿閘閥為好。**好是用蝶閥。對需要快關(guān)、快開的閥門，不宜處于一般的閘閥、截止閥。伊寧數(shù)字鎖定平衡閥批發(fā)。</p><div

不宜選用截止閥和閘閥，因為它們的密封面容易被析晶和沉淀物磨損。因此，應(yīng)選用球閥或旋塞閥較合適；也可選平板閘閥，但**好采用夾管閥。在閘閥的選型上，明桿單閘板比暗桿雙閘板適應(yīng)腐蝕性介質(zhì)；單閘板適于粘度大的介質(zhì)；楔式雙閘板對高溫和對密封面變形的適應(yīng)性比楔式單閘板要好，不會出現(xiàn)因溫度變化產(chǎn)生卡現(xiàn)象，特別是比不帶彈性的單閘板優(yōu)越。需要準確的調(diào)節(jié)小流量時，不宜需要截止閥，應(yīng)采用針型閥或節(jié)流閥。在需要保持閥后的壓力穩(wěn)定時，應(yīng)采用減壓閥。對高壓和超高壓介質(zhì)，常采用直角式截止閥，因為直角式截止閥通常是鍛鋼制作的，鍛鋼的耐壓能力相對比鑄鋼強。2.經(jīng)濟合理性對腐蝕性介質(zhì)，如果溫度和壓力不高，應(yīng)盡量采用非金屬閥門；如果溫度和壓力較高，可用襯里閥門，以節(jié)約貴重金屬。在選擇非金屬閥門時，仍應(yīng)考慮經(jīng)濟合理性。例如，在能夠用聚氯乙烯的情況下，就不用聚四氟乙烯，因為聚四氟乙烯比聚氯乙烯的價格要高。對溫度較高、壓力較大的場合，應(yīng)根據(jù)溫壓表，若普通碳素鋼閥門能滿足使用要求，就不宜采用合金鋼閥門，因為合金鋼閥門價格要高得多。對于粘度較大的介質(zhì)，要求有較小的流阻，應(yīng)采用Y型直流式截止閥、閘閥、球閥、旋塞閥等流阻小的閥門。新疆緩閉止回閥生產(chǎn)廠家。烏魯木齊臥式止回閥批發(fā)</p><p

對不含有氧或氧化劑的***、磷酸、醋酸、稀鹽酸等有較好的耐蝕性，同時對堿有很好的抗力。但不耐硝酸、濃***等氧化性酸的腐蝕，也不熔融金屬、硫和硫化物的腐蝕。切忌與氨接觸，它能使銅及銅合金產(chǎn)生應(yīng)力腐蝕破裂。選用時應(yīng)注意，銅合金的牌號不同，其耐腐蝕性有一定的差異。5.鋁閥門對強氧化性的濃硝酸的耐蝕性好，能耐有機酸和溶劑。但在還原性介質(zhì)、強酸、強堿中不耐蝕。鋁的純度越高，耐蝕性越好，但強度隨之下降，只能用作壓力很低的閥門或閥門襯里。6.鈦閥門鈦是活性金屬，在常溫下能生成耐蝕性很好的氧化膜。它能耐海水、各種氯化物和次氯酸鹽、濕氯、氧化性酸、有機酸、堿等的腐蝕。但它不耐較純的還原性酸，如***、鹽酸的腐蝕，切耐含有氧化劑的硝酸腐蝕。鈦閥門對孔蝕有良好的抗力。但在紅發(fā)硝酸、氯化物、甲醇等介質(zhì)中會產(chǎn)生應(yīng)力腐蝕。7.鋯閥門鋯也屬于活性金屬，它能生成緊密的氧化膜，它對硝酸、鉻酸、堿液、熔液、鹽液、尿素、海水等有良好的耐蝕性能，但不耐氫氟酸、濃***、王水的腐蝕，也不耐濕氯和氧化性金屬氯化物的腐蝕。8.陶瓷閥門以二氧化硅為主熔化燒結(jié)制成的閥門，如氧化鋯、氧化鋁、氮化硅等，除有極高的耐磨、耐溫。隔熱性能外。新疆控制閥門廠家</p><p
