硬密封氣動蝶閥產(chǎn)品概述
硬密封氣動蝶閥采用金屬密封結(jié)構(gòu)和三偏心閥體,可以在高溫和高壓力的管路中使用,蒸汽管路中常采用這種蝶閥進(jìn)行截止和調(diào)節(jié)控制,是一種氣動蒸汽蝶閥。這種氣動蝶閥采用硬密封閥座或者彈性密封閥座,不僅耐磨壽命長,還可以用于高溫度環(huán)境,可以在不高于600度的溫度下使用。采用雙向密封結(jié)構(gòu)的氣動硬密封蝶閥,不僅可以保護(hù)蝶閥免受反向介質(zhì)壓力的損傷,而且安裝不受介質(zhì)流向的影響。氣動三偏心蝶閥的氣動活塞執(zhí)行機(jī)構(gòu)采用壓縮空氣作動力源,通過活塞的運(yùn)動帶動曲臂進(jìn)行90度回轉(zhuǎn),達(dá)到使蝶閥的開關(guān)和調(diào)節(jié)氣動對夾蝶閥產(chǎn)品特點(diǎn)
1、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,使用壽命長等特點(diǎn)
2、采用氣動執(zhí)行器驅(qū)動,接通可以使閥門迅速關(guān)閉,配氣動定位器可以使蝶板停止在任意位置上,還能改善閥門的操作性能
3、蝶板密封面采用堆焊鈷基硬質(zhì)合金或者硬質(zhì)不銹鋼,密封面耐磨損,使用壽命長
4、這種對夾式硬密封蝶閥的閥板的密封圈采用金屬環(huán)代替橡膠環(huán)突破了軟密封蝶閥使用溫度低的缺點(diǎn),可用溫度的介質(zhì)管路
5、可以生產(chǎn)雙向密封結(jié)構(gòu),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
