<span style="font-size:16px;">如今閥門的類型和材料種類越來越多，閥門型號的編制也越來越復(fù)雜，閥門型號的標(biāo)準(zhǔn)化對閥門的設(shè)計、選用提供了方便，我國雖然有閥門型號編制的統(tǒng)一標(biāo)準(zhǔn)，但逐漸不能適應(yīng)閥門工業(yè)發(fā)展的需要。目前，我公司采用與市場上統(tǒng)一的編號方法。閥門型號編制方法規(guī)定了閥門的類型、驅(qū)動方式、連接方式、結(jié)構(gòu)形式、密封面材料、壓力和閥體材料代號的便是方法。此方法適用于各類閘閥、截止閥、節(jié)流閥、蝶閥、球閥、隔膜閥、旋塞閥、止回閥、排污閥、柱塞閥、減壓閥、疏水閥、安全閥等管道閥門產(chǎn)品。蝶閥又稱碟閥，啟閉件為盤形碟板并能繞閥體內(nèi)軸線旋轉(zhuǎn)的一種閥門。主要由閥體、閥桿、碟板和密封圈組成。閥體呈圓筒形，軸向長度短，內(nèi)置碟板。碟板由閥桿帶動，若轉(zhuǎn)過90°，便能完成一次啟閉。</span> </p><p> <span style="font-size:16px;">在驅(qū)動形式方面，樓宇內(nèi)常用就是手動（手柄、渦輪）和電動，氣動較少應(yīng)用。閥板的活動方式，受中線和偏心（單偏心、雙偏心、三偏心）結(jié)構(gòu)影響。蝶閥有三個心，閥桿中心線，閥體中心線，閥板密封線。這么說可能大家不太好記憶，在下面有一個視頻演示。先說中線蝶閥，這個是建筑領(lǐng)域常見的蝶閥結(jié)構(gòu)，通過閥板的外圓，擠壓橡膠閥座進(jìn)行密封，良好的彈性軟密封能實現(xiàn)零泄漏。偏心蝶閥，建筑領(lǐng)域常見的也就是雙偏心，單偏心因為沒能解決在開關(guān)過程中蝶板與閥座的剮蹭問題，所以采用的不多。三偏心多是鑄鋼材質(zhì)，硬密封，一般用在嚴(yán)酷工況下，像冶金，電力，石油化工，熱力，市政這些領(lǐng)域。在建筑領(lǐng)域里用到的多是球鐵軟密封或者鑄鋼軟密封。我們先看一個視頻，這是一個雙偏心蝶閥的剖視圖，紅色的為閥桿中</span><span style="font-size:16px;">心線，藍(lán)色為閥門中心線。在閥門打開的過程，會有兩個偏移量。平行和垂直向偏移。</span> 法蘭蝶閥處于完全開啟位置時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吳忠蝶閥多少錢,蝶閥" src="https://tyunfile.71360.com/UploadFile/gscyhwz/637318064276845703/8763448.png"></div><p> <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;">在雙位調(diào)節(jié)、縮口地通道、低噪聲、有氣穴和氣化現(xiàn)象，向大氣少量滲漏，具有磨蝕性介質(zhì)時，可以選用蝶閥。在特殊工況條件下節(jié)流調(diào)節(jié)，或要求密封嚴(yán)格，或磨損嚴(yán)重、低溫(深冷)等工況條件下使用蝶閥時，需使用特殊設(shè)計金屬密封帶調(diào)節(jié)裝置地三偏心或雙偏心地**蝶閥。中線蝶閥適用于要求達(dá)到完全密封、氣體試驗泄漏為零、壽命要求較高、工作溫度在-10度～150度的淡水、污水、海水、鹽水、蒸汽、天然氣、食品、藥品、油品和各種酸堿及其他管路上。軟密封偏心蝶閥適用于通風(fēng)除塵管路的雙向啟閉及調(diào)節(jié)；金屬對金屬線密封雙偏心蝶閥適用于城市供熱、供氣、；金屬對金屬面密封三偏心蝶閥除作為大型變壓吸附(PSA)氣體分離裝置程序控制閥使用外，還可***用于石油、石化、化工、冶金、電力等領(lǐng)域，時閘</span><span
