法蘭式氣動(dòng)硬密封蝶閥 特點(diǎn) 法蘭式氣動(dòng)硬密封蝶閥D673H 金屬密封三偏心蝶閥的密封原理利用偏心結(jié)構(gòu),做到了閥門啟閉時(shí)蝶板與閥座間幾乎無磨擦現(xiàn)象發(fā)生。閥桿的扭矩通過蝶板直接傳遞至密封面,從而杜絕了打開普通閥門時(shí)所常見的跳躍現(xiàn)象。這意味著偏心蝶閥幾乎可以從0開度開始即進(jìn)入可調(diào)控區(qū)域,直至90開度。其正常調(diào)控比是一般蝶閥的2倍以上,調(diào)控比zui高可高達(dá)100:1以上。這為偏心蝶閥作為調(diào)控閥使用創(chuàng)造了良好的條件。 ■金屬密封可適用于帶稍許顆粒、漿液的介質(zhì)中 ■適用溫度可達(dá)425℃,zui高壓力6.4MPa ■密封時(shí)幾乎無摩擦,保證扭矩更小,密封性更好 ■法蘭對(duì)夾孔連接適用多種標(biāo) ◇ D643H 參數(shù) 驅(qū)動(dòng) | 壓縮空氣5~7bar(可帶手輪) | 公稱通經(jīng) | 50~1000mm | 公稱壓力 | 1.6~6.4MPa | 適用溫度 | -40~+420℃ | 連接方式 | 法蘭、對(duì)夾 | 閥結(jié)構(gòu) | 三偏心 | 閥體材質(zhì) | 304、316、碳鋼 | 閥板材質(zhì) | 304、316、碳鋼 | 密封材質(zhì) | 本體、合金 | 適用介質(zhì) | 氣體、水及油類等(高溫場(chǎng)合) | 可選附件 | 限位開關(guān)、定位器、電磁閥、減壓閥 |
