Q971F型电动对夹式球阀属于电动阀类。球阀主要用于截断或接通管道和设备介质，也可用于流体的调节与控制，V型球阀能够进行比较精确的流量调节与控制，而三通型则用于分配介质和改变介质的流向。球阀流体阻力小，结构简单，体积小，重量轻，紧密可靠，操作维修方便，不会引起阀门密封面的侵蚀，适用范围广。【结构图】【Q971F电动对夹式球阀尺寸表】订货号M41516F64M41516F65M41516F66M41516F67M41516L68M41516L69M41516L70M41516L71M41516P72直径mm.1520253240506580100尺寸mm.DN15DN20DN25DN32DN40DN50DN65DN80DN100通径mm.1520253240506580100Amm.207,5207,5207,5207,5256,5256,5256,5256,5381Bmm.122,5122,5122,5122,5156,5156,5156,5156,5242Cmm.6868686894949494137Dmm.163,5163,5163,5163,5185185185185234Xmm.444444444444444444Emm.35384250607095118140ΦGmm.90100110130140165185200220ΦMmm.657585100110125145160180ΦNmm.M12/4M12/4M12/4M16/4M16/4M16/4M16/4M16/8M16/8ΦRGAS1/8"1/8"1/8"1/8"1/8"1/8"1/8"1/8"1/8"T.ofcycle50/60Hzs.15-12,515-12,515-12,515-12,515-12,515-12,515-12,515-12,515-12,5Hmm.234,5237,5243249,5295302325335395重量Kg.6,77,37,99,315,41519,729,344,9【Q971F电动对夹式球阀零部件材料】1)轴Shaft不锈钢ANSI3161.4401UNIX5CrNiMo17122)螺母夹Nutholder不锈钢ANSI3041.4301UNIX5CrNi18103)防松螺母Locknut不锈钢ANSI3041.4301UNIX5CrNi18104)弹簧Spring不锈钢ANSI3011.4310UNIX12CrNi17075)垫圈Washer不锈钢ANSI3041.4301UNIX5CrNi18106)压紧环型螺母Glandnutring不锈钢ANSI3041.4301UNIX5CrNi18107)顶部密封至psealing**聚四氯乙烯P.T.F.E.8)O环O-Ring**氟橡胶VITON9)密封圈Seals聚四氯乙烯P.T.F.E.10)O环O-Ring氟橡胶VITON11)环型螺母密封Ringnutsealing聚四氯乙烯P.T.F.E.12)底部密封Bot至msealing聚四氯乙烯P.T.F.E.13)环型螺母Ringnut*不锈钢ANSI3161.4401UNIX5CrNiMo171214)球体Ball*不锈钢ANSI3161.4401UNIX5CrNiMo171215)阀体Body*不锈钢ANSI3161.4408*不锈钢304按要求提供**DN125-150聚四氯乙烯密封没有O环。【产品特性】●流体范围：空气、水、气体、石油和石化产品、腐蚀性介质。●工作压力:PN16,PN25-PN40-PN64（根据要求发货）●工作温度:-20℃至+150℃(+200℃特殊密封)●通用规格:BS5351("防火"根据要求遵循BS6755)●法兰:UNI2223和2229PN16DIN2501BL.1UNI(PN25-40-64-100)根据要求发货不锈钢ANSIB16.5-不锈钢ANSIB16.10(150RF,300RF,600RF)●带保温套的阀门根据要求发货)
