气动V型调节球阀气动V型球阀采用圆柱型弹簧预载的带补偿性可动金属阀座结构，密封性能可靠。球芯与阀座不会产生卡阻或脱离，使用寿命长。球芯上的V形切口与金属阀座之间具有剪切作用，特别适用于控制高粘度，含纤维、固体颗粒及浆料等介质。结构制造纸工业的纸浆显得尤为优越。阀门的流通能力大、压力损失小、且介质不会沉积在阀体中腔，阀门不仅具有近似等有分比的流量特性、可调范围大，最大可调比为100：1，还具有精确调节与可靠定位的功能。气动V型调节球阀气动V型球阀主要零件材质表：零件名称材质阀体、阀盖WCBCF8密封圈2Cr13+氮化304+氮化球体2Cr13+硬格304+硬格阀座、阀杆2Cr13304垫片柔性石墨+不锈钢柔性石墨+不锈钢双头螺柱35CrMoA1Cr18Ni9Ti气动V型调节球阀气动V型球阀产品性能规范：公称压力试验压力（MPa)适用介质适用温度壳体试验密封试验1.62.41.76水、油、气及高粘度，含纤维、固体颗粒等介质-28℃～≤550℃2.53.752.754.06.04.4应用规范连接法兰JB79-59GB9113HG20592-97ANSIB16.5检验试验JB/T9092-99API598气动V型调节球阀气动V型球阀主要外形尺寸：公称或压力级公称口径尺寸（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-)
