特點(diǎn)及用途：
美標(biāo)焊接式蝶閥,硬密封焊接蝶閥,三偏心焊接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。
美標(biāo)焊接式蝶閥,硬密封焊接蝶閥,三偏心焊接蝶閥的密封原理：
美標(biāo)焊接式蝶閥,硬密封焊接蝶閥,三偏心焊接蝶閥具有雙向無氣泡緊密壯關(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。
三重偏心幾何形狀：
偏心1 閥軸位于閥座軸后面，使得密封能夠完全緊密環(huán)繞接觸整個(gè)閥座。
偏心2 閥軸中心線偏離管道和閥門中心線，這就免受閥門開啟和關(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)閉和開啟過程中消除摩擦作用，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，使得閥門能夠?qū)崿F(xiàn)雙向緊密關(guān)閉密封的彈性使得閥門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)。
