法蘭浮動鍛鋼球閥采用三片式鍛鋼分體設(shè)計,浮動球體結(jié)構(gòu)。是專為高壓工況設(shè)計,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,保證了出口端的密封。
法蘭浮動鍛鋼球閥結(jié)構(gòu)簡單、密封性能好,可以取代傳統(tǒng)的固定球閥,以節(jié)省費用。
法蘭浮動鍛鋼球閥可根據(jù)客戶需求,設(shè)計滿足高溫或超低溫的工況需要。
應用規(guī)范:
1、設(shè)計、制造按GB12237-89
2、結(jié)構(gòu)長度按GB12221-89
3、法蘭連接:JB/T79-94
4、閥門檢驗與試驗按API STD.598
