美標(biāo)三偏心硬密封凸耳式蝶閥
采用標(biāo)準(zhǔn): 設(shè)計(jì)制造:API609、MSS SP-67、MSS SP-68 檢驗(yàn)和試驗(yàn):API598 法蘭連接:ASME B16.5(NPS≤24)、ASME B16.47 B系列 對(duì)焊端:ASME B16.25 結(jié)構(gòu)長(zhǎng)度:API609 溫壓等級(jí):ASME B16.34 特點(diǎn)及用途: 三偏心金屬密封蝶閥系列是我公司主要產(chǎn)品,大量使用在冶金、輕工、電力、石油化工、煤氣水道等領(lǐng)域。 |
三偏心金屬密封蝶閥的密封原理:
三偏心蝶閥具有雙向無(wú)氣泡緊密壯關(guān)閉性能。這種幾何形狀保證閥瓣密封只是在關(guān)閉位置時(shí)才與閥體閥座接觸,因此不會(huì)產(chǎn)生摩擦或磨損,并且產(chǎn)生一種扭矩使得彈性密封具有足夠的“焊接”性能,確保密封接觸的均勻一致性。
三重偏心幾何形狀:
偏心1 閥軸位于閥座軸后面,使得密封能夠緊密環(huán)繞接觸整個(gè)閥座。
偏心2 閥軸中心線偏離管道和閥門(mén)中心線,這就免受閥門(mén)開(kāi)啟和關(guān)閉的干擾。
偏心3 閥座錐體軸偏離閥軸中心線,這樣就可以在關(guān)閉和開(kāi)啟過(guò)程中消除摩擦作用,并且實(shí)現(xiàn)環(huán)繞整個(gè)閥座的均勻一致的壓縮密封效果。
使用壽命更長(zhǎng)的無(wú)摩擦密封:
(1)作為標(biāo)準(zhǔn)配置,閥座采用Cr13合金或鎢鉻鈷合金硬面。
(2)密封墊采用螺旋盤(pán)繞不銹鋼/石墨,用于實(shí)現(xiàn)零泄漏。
(
3)關(guān)閉期間的扭矩產(chǎn)生閥座力,并均勻一致的作用在整個(gè)圓周周圍。彈性密封彎曲并充滿活力,保持了閥座的形狀。壓縮力沿著周長(zhǎng)均勻作用,使得閥門(mén)能夠?qū)崿F(xiàn)雙向緊密關(guān)閉密封的彈性使得閥門(mén)閥體和閥瓣能夠接觸或擴(kuò)張,避免了由于溫度波動(dòng)而產(chǎn)生堵塞的危險(xiǎn)。這種裝置是能夠自行調(diào)整對(duì)準(zhǔn)。
