可以采用各種各樣的材料制成，該閥門主要用于“開(kāi)”或者“關(guān)”，但是備有特制形式的柱塞或特殊的套環(huán)，也可以用于調(diào)節(jié)流量。蝶閥蝶閥的蝶板安裝于管道的直徑方向。在蝶閥閥體圓柱形通道內(nèi)，圓盤形蝶板繞著軸線旋轉(zhuǎn)，旋轉(zhuǎn)角度為0°~90°之間，旋轉(zhuǎn)到90°時(shí)，閥門則牌全開(kāi)狀態(tài)。蝶閥結(jié)構(gòu)簡(jiǎn)單、體積小、重量輕，只由少數(shù)幾個(gè)零件組成。而且只需旋轉(zhuǎn)90°即可快速啟閉，操作簡(jiǎn)單，同時(shí)該閥門具有良好的流體控制特性。蝶閥處于完全開(kāi)啟位置時(shí)，蝶板厚度是介質(zhì)流經(jīng)閥體時(shí)的阻力，因此通過(guò)該閥門所產(chǎn)生的壓力降很小，故具有較好的流量控制特性。蝶閥有彈密封和金屬的密封兩種密封型式。彈性密封閥門，密封圈可以鑲嵌在閥體上或附在蝶板周邊。采用金屬密封的閥門一般比彈性密封的閥門壽命長(zhǎng)，但很難做到完全密封。金屬密封能適應(yīng)較高的工作溫度，彈性密封則具有受溫度限制的缺點(diǎn)。如果要求蝶閥作為流量控制使用，主要的是正確選擇閥門的尺寸和類型。蝶閥的結(jié)構(gòu)原理尤其適合制作大口徑閥門。蝶閥不僅在石油、煤氣、化工、水處理等一般工業(yè)上得到***應(yīng)用，而且還應(yīng)用于熱電站的冷卻水系統(tǒng)。常用的蝶閥有對(duì)夾式蝶閥和法蘭式蝶閥兩種。</p><div
