Q41F-16P不銹鋼軟密封球閥產(chǎn)品概述：
一、Q41F-16P不銹鋼軟密封球閥用途和性能規(guī)范:
Q41F型球閥適用于中、小口徑管路的各種壓力、溫度和介質(zhì)下控制接通或截斷管路介質(zhì)的啟閉裝置;靠介質(zhì)壓力將球體壓緊在出口端閥座上,其使用壓力和通徑受到一定限制.采用90°傳動,故開關方便迅速,可以實行快速啟閉.
二、Q41F-16P不銹鋼軟密封球閥操作原理和結(jié)構(gòu)說明:
1、球閥通道平整光滑便于管道掃線清洗,可以輸送漿液及固體顆粒等介質(zhì).
2、采用PTFE（特氟隆）等材料作為密封,具有良好潤滑性和彈性,與球體摩擦系小,使用壽命長.
3、啟閉迅速,啟閉時只需把球體轉(zhuǎn)動90°,方便而迅速.
4.球閥的流體阻力小,全開時球體通道、閥體通道和連接管道的截面積相等,并且成直線想通,介質(zhì)流過球閥,相當于流過一段直通的管子,在各類閥門中球閥的流體阻力zui小.
5、經(jīng)配置有手動、蝸輪驅(qū)動、氣動、電動（防爆）可以實現(xiàn)遠程自動控制,能滿足用戶的各種工況使用要求.
