style="font-size:16px;">心線，藍色為閥門中心線。在閥門打開的過程，會有兩個偏移量。平行和垂直向偏移。</span> </p><p> <span style="font-size:16px;">蝶閥又叫翻板閥，是一種結構簡單的調(diào)節(jié)閥，可用于低壓管道介質(zhì)的開關控制的蝶閥是指關閉件(閥瓣或蝶板)為圓盤，圍繞閥軸旋轉(zhuǎn)來達到開啟與關閉的一種閥。市場上常見的蝶閥按結構分為中線蝶閥、單偏心蝶閥、雙偏心蝶閥和三偏心蝶閥，其中雙偏心蝶閥和三偏心蝶閥能實現(xiàn)密封副極短時間內(nèi)脫離，減少密封副之間的摩擦，從而實現(xiàn)延長閥門壽命和減小啟閉力矩的目的。蝶閥在全關狀態(tài)下，介質(zhì)壓力作用于閥板，從上圖中可以看出第二偏心導致閥板旋轉(zhuǎn)中心（即閥軸中心）兩側面積是不一樣的，我們知道F=P*s,那么閥板旋轉(zhuǎn)中心（即閥軸中心）兩側所受壓力也是不一樣的，而蝶閥的開啟是蝶板圍繞閥軸做逆時針轉(zhuǎn)動來實現(xiàn)，那么我們可以發(fā)現(xiàn)，當雙偏心蝶閥和三偏心需要開啟時，由于閥軸中心兩側的壓力不平</span><span

style="font-size:16px;">原始的蝶閥是一種簡單的，且關閉不嚴的擋板閥．通常在水管路系統(tǒng)中作為流量調(diào)節(jié)閥和阻尼閥使用。隨著防化學腐蝕的合成橡膠在蝶閥上的應用，蝶閥的性能得以提高。由于合成橡膠具有耐腐蝕、抗沖蝕，尺寸穩(wěn)定，回彈性好，易于成形，成本低廉等特點，并可根據(jù)不同的使用要求選擇不同性能的合成橡膠，以滿足蝶閥的使用工況條件，因而被用于制造蝶閥的襯里和彈性閥座。閥座密封圈由軟性T形密封環(huán)兩側多層不銹鋼片組成。閥板與閥座的密封面為斜圓錐結構，在閥板斜圓錐表面堆焊耐溫、耐蝕合金材料;固定在調(diào)節(jié)環(huán)壓板之間的彈簧與壓板上調(diào)節(jié)螺栓裝配一起的結構。這種結構有效地補償了軸套與閥體之間的公差帶及閥桿在介質(zhì)壓力下的彈性變形，解決了閥門在雙向互換的介質(zhì)輸送過程中存在的密封問題。采用軟性T型兩側多層不銹鋼片組成密封圈，具有金屬硬密封和軟密封的雙重優(yōu)點，無論在低溫和高溫情況下，均具有零滲漏的密封性能。這也與閥門的質(zhì)量有關，選擇質(zhì)量的閥門可能</span><span

style="font-size:16px;">由于聚四氟乙烯(PTFE)具有耐腐蝕性強、性能穩(wěn)定、不易老化、摩擦系數(shù)低、易于成形、尺寸穩(wěn)定，并且還可通過填充、添加適當材料以改善其綜合性能，得到強度更好、摩擦系數(shù)更低的蝶閥密封材料，克服了合成橡膠的部分局限性，因而以聚四氟乙烯為的高分子聚合材料及其填充改性材料在蝶閥上得到了的應用，從而使蝶閥的性能得到更進一步的提高，出現(xiàn)了溫度、壓力范圍更廣，密封性能、使用壽命更長的蝶閥。為滿足高低溫度、強沖蝕、長壽命等工業(yè)應用的使用要求，近十幾年來，金屬密封蝶閥得到了很大的發(fā)展。隨著耐高溫、耐低溫、耐強腐蝕、耐強沖蝕、**度合金材料在蝶閥中的應用，使金屬密封蝶閥在高低溫度、強沖蝕、長壽命等工業(yè)領域得到了***的應用，出現(xiàn)了大口徑(9750mm)、高壓力()、寬溫度范圍(-102～606℃)的蝶閥，從而使蝶閥的技術達到一個全新的水平。</span>
