Q41F不銹鋼球閥產(chǎn)品說明
Q41F不銹鋼球閥的球體是浮動(dòng)的,在介質(zhì)壓力作用下,球體能產(chǎn)生一定的位移并緊壓在出口端的密封面上,保證出口端密封。浮動(dòng)球閥的結(jié)構(gòu)簡單,密封性好,但球體承受工作介質(zhì)的載荷全部傳給了出口密封圈,因此要考慮密封圈材料能否經(jīng)受得住球體介質(zhì)的工作載荷,在受到較高壓力沖擊時(shí),球體可能會發(fā)生偏移。這種結(jié)構(gòu),一般用于中低壓球閥。
Q41F不銹鋼球閥產(chǎn)品特點(diǎn)
1、在各種閥門中,球閥的流動(dòng)阻力最小,全徑球閥打開時(shí),球體通道、閥體通道和連接管徑相等并成一直徑,介質(zhì)幾乎可以毫無損失的流過
2、球閥旋轉(zhuǎn)90°即可全關(guān)全開,啟閉迅速。與相同規(guī)格的閘閥、截止閥比較、球閥體積小、重量輕,便于管道安裝
