style="font-size:16px;">橡膠密封蝶閥缺點是作節(jié)流使用時，由于使用不當(dāng)會產(chǎn)生氣蝕，使橡膠座剝落、損傷等情況發(fā)生。為此，現(xiàn)在國際上又開發(fā)金屬密封蝶閥，氣蝕區(qū)減小，近幾年我國也開發(fā)了金屬密封蝶閥，在日本近年來還開發(fā)耐氣蝕、低振動、低噪聲的梳齒形蝶閥。一般密封座的壽命在正常情況下，橡膠15年-20年，金屬的80年-90年。但如何正確選用則要根據(jù)工況要求。蝶閥的開度與流量之間的關(guān)系，基本上呈線性比例變化。如果用于控制流量，其流量特性與配管的流阻也有密切關(guān)系，如兩條管道安裝閥門口徑、形式等全相同，而管道損失系數(shù)不同，閥門的流量差別也會很大。如果閥門處于節(jié)流幅度較大狀態(tài)，閥板的背面容易發(fā)生氣蝕，有損壞閥門的可能，一般均在15°外使用。蝶閥處于中開度時，閥體與蝶板前端形成的開口形狀以閥軸為中心，兩側(cè)形成完成不同的狀態(tài)，一側(cè)的蝶板前端順流水方向而動，另一側(cè)逆流水方向而動，因此，一側(cè)閥體與閥板形成似噴嘴形開口，另一側(cè)類似節(jié)流孔形開口</span><span

style="font-size:16px;">在連接方式方面，常見有對夾，支耳，法蘭，其中對夾方式在建筑樓宇領(lǐng)域，應(yīng)用比較多，性價比較高。對夾式蝶閥是用雙頭螺栓將閥門連接在兩管道法蘭之間。法蘭式蝶閥是閥門上帶有法蘭，用螺栓將閥門上兩端法蘭連接在管道法蘭上。支耳式蝶閥有兩種連接孔，一種是貫穿孔，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。在閥體材質(zhì)方面，大約是兩類，鑄鐵和鑄鋼。其中鑄鐵如果沒有特指球墨鑄鐵，就是用灰鑄鐵。鑄鋼也是一樣，不特指不銹鋼的話通常就是用碳鋼。在密封方面，分軟密封和硬密封兩種，樓宇內(nèi)用比較多的就是軟密封，材質(zhì)多為EPDM或者NBR。</span>

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
