電動V型調(diào)節(jié)球閥采用圓柱型彈簧預載的帶補償性可動金屬閥座結(jié)構(gòu)，密封性能可靠。球芯與閥座不會產(chǎn)生卡阻或脫離，使用壽命長。球芯上的V形切口與金屬閥座之間具有剪切作用，特別適用于控制高粘度，含纖維、固體顆粒及漿料等介質(zhì)。結(jié)構(gòu)制造紙工業(yè)的紙漿顯得尤為*。閥門的流通能力大、壓力損失小、且介質(zhì)不會沉積在閥體中腔，閥門不僅具有近似等有分比的流量特性、可調(diào)范圍大，zui大可調(diào)比為100：1，還具有精確調(diào)節(jié)與可靠定位的功能。電動V型調(diào)節(jié)球閥主要零件材質(zhì)表 零件名稱材質(zhì)閥體、閥蓋WCBCF 8密封圈2Cr13+氮化304+氮化球體2Cr13+硬格304+硬格閥座、閥桿2Cr13304墊片柔性石墨+不銹鋼柔性石墨+不銹鋼雙頭螺柱35CrMoA1Cr18Ni9Ti 電動V型調(diào)節(jié)球閥產(chǎn)品性能規(guī)范 公稱壓力試驗壓力（MPa)適用介質(zhì)適用溫度殼體試驗密封試驗1.62.41.76水、油、氣及高粘度，含纖維、固體顆粒等介質(zhì)-28℃～≤550℃2.53.752.754.06.04.4應用規(guī)范連接法蘭JB79-59 GB9113 HG20592-97 ANSI B16.5檢驗試驗JB/T9092-99 API 598 電動V型調(diào)節(jié)球閥主要外形尺寸 公稱或壓力級公稱口徑尺寸（mm）（mm）（in）WLW1L1dd1H1HPN1.6MPa25-50-25-64385720040-60-25-82496320550-751243262100609222565-801453872.51207510023580-1001654582.513189108260100-1151945097158113117270125-13521055105180140140320150-16022965114.5216164177340200-20024380121.5268205200390250-24029790148.5326259252420300--338-169-300270510PN2.5MPa25-50-25-64385720040-60-25-82496320550-751243262100609222565-851453872.51207510023580-1001654582.513189108260100-1151945097158113117270125-13521055105180140140320150-16022965114.5216164177340200-20024380121.5268205200390250-24029792148.5326259252420300--338-169-300270510ClASS15025-50-25-6438572004011/265-25-82496320550275124326210060922256521/2851453872.5120751002358031001654582.51318910826010041151945097158113117270125513521055105180140140320150616022965114.5216164177340200820024380121.52682052003902501024029792148.532625925242030012-338-169-上海VQ947H電動V型調(diào)節(jié)球閥_圣核閥門制造(上海)有限公司
