style="text-indent:25px">蝶閥的結(jié)構(gòu)長度和總體高度較小，開啟和關(guān)閉速度較快，且具有良好的流體控制特性。蝶閥的結(jié)構(gòu)原理適合于制作大口徑閥門。當(dāng)要求蝶閥作控制流量使用時，重要的是正確選擇蝶閥的規(guī)格和類型，使之能恰當(dāng)?shù)?、有效地工作。通常，在?jié)流、調(diào)節(jié)控制與泥漿介質(zhì)中，要求結(jié)構(gòu)長度短、啟閉速度快、低壓截止(壓差小)，推薦選用蝶閥。在雙位調(diào)節(jié)、縮徑的通道、低噪聲、有氣穴和汽化現(xiàn)象、向大氣少量滲漏、具有磨蝕性介質(zhì)時，可選用蝶閥。在特殊工況條件下節(jié)流調(diào)節(jié)，或要求密封嚴格、磨損嚴重、低溫(深冷)等工況條件下。</p><p style="text-indent:25px">法蘭蝶閥門關(guān)嚴后，由于介質(zhì)或環(huán)境溫度的變化，閥門部件的熱膨脹會使閘板和閥座之間的壓力變大。這個力反映到閥桿螺紋上，就為再次開啟閥門帶來困難，所以開啟閥門時所需的轉(zhuǎn)矩(即加在閥桿螺母上的轉(zhuǎn)矩)一般要比關(guān)閉閥門時所需的轉(zhuǎn)矩來得大。此外，對于一對互相接觸的密封面來說，它們之間的樸摩擦系數(shù)也比動摩擦系數(shù)大，所以要使它們從靜止?fàn)顟B(tài)產(chǎn)生相對位移時，必須加較大的力，以克服靜摩擦力。這一情況，在關(guān)閉后再次開啟的閥門中更加明顯。減壓閥前后裝有壓力表，方便觀察閥前和閥后的壓力。</p><div

style="text-indent:25px">蝶閥處于徹底開啟方位時，蝶板厚度是介質(zhì)流經(jīng)閥體時的阻力，因而通過該閥門所產(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，但很難做到徹底密封。金屬密封能習(xí)慣較高的工作溫度，彈性密封則具有受溫度限制的缺點。如果要求蝶閥作為流量控制運用，主要的是正確選擇閥門的尺度和類型。蝶閥的結(jié)構(gòu)原理特別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)上得到普遍應(yīng)用，并且還應(yīng)用于熱電站的冷卻水系統(tǒng)。蝶閥可以運送泥漿，在管道口積存液體少。江西軟密封高性能蝶閥蝶閥哪家可靠</p><p
