D643H氣動(dòng)多層次法蘭金屬硬密封蝶閥
嚴(yán)格按照國(guó)家GB/T13927-92閥門壓力試驗(yàn)標(biāo)準(zhǔn)生產(chǎn)。
采用精密彈性密封圈和三偏心多層次金屬硬密封結(jié)構(gòu),使閥座與碟板密封面均采用不同硬度和不銹鋼制作,具有良好的耐腐蝕性,使用壽命長(zhǎng),本閥均有雙向密封功能,氣動(dòng)多層次硬密封蝶閥廣泛用于
介質(zhì)溫度≤425℃的治金、電力、石油化工、以及給排水和市政建設(shè)等工業(yè)管道上,作調(diào)節(jié)流量和載斷流體使用。
D643H氣動(dòng)多層次法蘭金屬硬密封蝶閥性能特點(diǎn):
1,采用三偏心密封結(jié)構(gòu),閥座與蝶板幾乎無磨損,具有越觀越緊的密封功能。
2,密封圈選用不銹鋼制作,具有金屬硬密封和彈性密封的雙重優(yōu)點(diǎn),無論在低溫和高溫的情況下,均具有優(yōu)良的密封性能,具有耐腐蝕,使用壽命長(zhǎng)等特點(diǎn)。
3,碟板密封面采用堆焊鈷基硬質(zhì)合金,密封面耐磨損,使用壽命長(zhǎng).大規(guī)格蝶板采用絎架結(jié)構(gòu),強(qiáng)度高,過流面積大,流阻小。
4,D643H氣動(dòng)多層次硬密封蝶閥具有雙向密封功能,安裝時(shí)不受介質(zhì)流向的限制,也不受空間位置的影響,可在任何方向安裝。氣動(dòng)驅(qū)動(dòng)裝置可多工位安裝,方便使用。
