style="font-size:16px;">選用蝶閥應(yīng)遵循的原則：⑴與閘閥、截止閥、球閥、旋塞閥等相比，蝶閥的結(jié)構(gòu)尺寸小，重量**輕，價格便宜，故對于大尺寸管道，用蝶閥代替其他切斷閥對降低裝置建設(shè)成本是非常有利的;⑵與閘閥、截止閥、球閥、旋塞閥等相比，其密封可靠性**差，故不宜用于高溫(如200℃及以上)、高壓(如Class600及以上)的介質(zhì)工況，但個別工廠的特殊設(shè)計例外;⑶對于軟密封蝶閥，雖然價格會更便宜，但受溫度和壓力的限制，高溫高壓時不能使用;⑷蝶閥無密閉閥腔，適宜用于低溫介質(zhì)工況或可能發(fā)生氣化的介質(zhì)工況;⑸不能用于有通球要求的管路切斷;⑹可以做襯里;⑺適宜用于壓力脈動介質(zhì)工況和可能產(chǎn)生汽蝕的介質(zhì)工況;適宜用于高壓氧氣工況;適宜用于可能產(chǎn)生沖刷或沖刷腐蝕的介質(zhì)工況;⑻相對于閘閥、球閥來說，由于蝶閥的壓</span><span

style="font-size:16px;">對建筑里常用的軟密封蝶閥來說，它的三種連接形式比較大的差異是價格方面，從對夾，支耳，法蘭逐步提高的。其次是性能方面。在選擇使用的螺栓時，對夾連接是采用雙頭螺栓將蝶閥閥體固定在管道的法蘭中間，而法蘭連接則需要一對螺栓分別將蝶閥的兩片法蘭固定在管道法蘭中間。支耳蝶閥是比較特殊的一種，它有兩種連接孔，一個是貫穿孔，這種形式和對夾連接的一樣需要雙頭螺栓固定。另外一種就是螺紋孔，在連接過程中，相當(dāng)于起到了兩個螺母的功能，用兩個螺栓分別固定在管道法蘭中間。大口徑蝶閥能不能夾的住的問題。實際上對夾蝶閥的重量相比是較輕的，靠管道的夾持力是足以保證蝶閥牢固的安裝在管道中間，也不需要專門的做支撐。因此在非必要工況下，其造價低，安裝方便等優(yōu)點，是建議使用的。</span> </p><p> <span style="font-size:16px;">蝶閥材質(zhì)有高分子聚合物和金屬兩類，聚合物閥座主要適用于溫度較低的工況，金屬密封閥座蝶閥雖然能滿足較高的溫度和壓力工況，但金屬閥座的彈性較聚合物閥座低，密封性能較差，蝶閥各種性能的改善與其不斷改進密切相關(guān)。目前，不銹鋼蝶閥作為一種用來實現(xiàn)管路系統(tǒng)通斷及流量控制的部件，已在石油、化工、冶金、水電等許多領(lǐng)域中得到極為***地應(yīng)用。在已公知的蝶閥技術(shù)中，其密封形式多采用密封結(jié)構(gòu)，密封材料為橡膠、聚四氟乙烯等。由于結(jié)構(gòu)特征的限制，不適應(yīng)耐高溫、高壓及耐腐蝕、抗磨損等行業(yè)。不銹鋼蝶閥現(xiàn)有一種比較先進的蝶閥是三偏心金屬硬密封蝶閥，閥體和閥座為連體構(gòu)件，閥座密封表面層堆焊耐溫、耐蝕合金材料。多層軟疊式密封圈固定在閥板上，這種蝶閥與傳統(tǒng)蝶閥相比具有耐高溫，操作輕便，啟</span><span
