球阀和旋塞阀是同属一个类型的阀门，只有它的关闭件是个球体，球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。球阀在管路中主要用来做切断、分配和改变介质的流动方向。球阀是近年来被广泛采用的一种新型阀门.产品名称：美标法兰球阀产品型号：Q41公称尺寸：1/2”-8”公称压力：150Lb-600Lb10K-40K阀体材质：WCB、CF8、CF8M、CF3、CF3M美标球阀产品性能规范公称压力(PN)1.62.54.06.4壳体试验压力2.43.86.09.6密封试验(液)1.82.84.47.0密封试验(气)0.5～0.7适用介质CPR水、油品、蒸气硝酸类醋酸类适用温度≤200℃美标球阀主要零件材料名称WCB类CF8类CF3类CF8M类CF3M类阀体左体A216-WCBA315-CF8A35-CF3A351-CF8MA351-CF3M球体B2-B8A105-1025A182-F304LA182-F304LA132-F316A182-F316LB8以上A216-WCBA351-CF8MA351-CF3A351-CF8MA351-CF3M阀杆A182-F6aA182-F304A182-F304LA182-F336A182-F316L阀座PTFE/增强PTFE/NYLINPTFE/ReinforcedPTFE/Nyion阀座支承圈A105-1025A182-F304A182-F304LA182-F316A182-F316L弹簧3yc-7/17-49HO形圈NBR氟橡胶螺柱A193-B7A193-B8螺母A194-2HA194-8日标球阀10K主要连接尺寸及重量尺寸inch1/2"3/4"1"1-1/2"2"2-1/2"3"4"5"6"8"10"DN15202540506580100125150200250Lmm108117127165178190203229356394457533Hmm59637597107142152178252272342345Wmm1301301602302304004007001100110015001500重量kg2.33.04.57.09.515.019.033.058.093.0160.0200.0日标球阀20K主要连接尺寸及重量尺寸inch1/2"3/4"1"1-1/2"2"2-1/2"3"4"5"6"8"10"DN15202540506580100125150200250Lmm140152165190216241283305381403502568Hmm59637597107142152178252272342345Wmm1301301602302304004007001100110015001500重量kg2.53.55.510.514.523.530.055.081.0118.0200.0250.0美标球阀150Lb外形尺寸和连接尺寸公称通径NPS单位LDTGCn-φdWHinmm1/2"15mm10889123560.54-1511572in4.253.50.471.382.384-0.594.5328.33/4"20mm117981243704-1511576in4.613.860.471.692.764-0.594.5329.91"25mm127108125179.54-1515092in54.250.4723.134-0.595.93.6211/2"40mm16512714.37398.54-16200123in6.550.562.883.884-0.627.874.842"50mm17815215.992120.54-19200132in76.000.6253.624.754-0.757.875.2021/2"65mm19017817.5105139.54-19320164in7.570.694.125.5.4-0.7512.66.453"80mm20319019.1127152.44-19320173in87.500.75564-0.7512.66.84"100mm22922923.9157190.58-19450210in990.946.197.58-0.7517.728.266"150mm39427926216241.58-228000288in15.510.981.028.59.508-0.8831.51.348"200mm45734329270298.58-221120374in18.0013.501.1210.6211.758-0.8844.1014.7210"250mm5334063132436212-251420366in20.98161.212.7514.7512-155.1214.4012"300mm6104833238143212-251420412in24191.26151712-155.1216.22美标球阀300Lb外形尺寸和连接尺寸公称通径NPS单位LDTGCn-φdWHinmm1/2"15mm14095153566.54-1511572in5.513.740.591.382.624-0.594.5328.33/4"20mm152117164382.54-1911576in5.984.610.621.693.254-0.754.5329.91"25mm1651241851894-1915092in6.54.90.7123.54-0.755.93.6211/2"40mm19015620.773114.54-22200123in7.56.120.812.884.514-0.887.874.842"50mm21616522.3921278-19200132in8.56.50.883.6258-0.757.875.2021/2"65mm24119025.41051498-22320164in9.57.514.125.878-0.8812.66.453"80mm28321028.5127168.58-22320173in11.258.25101256.628-0.8812.66.84"100mm30525431.81572008-22450210in12101.256.197.888-0.8817.728.266"150mm40331836.621627012-221120336in15.87512.51.448.510.6212-0.8844.1013.238"200mm5023814227033012-251420385in19.761516.510.6212.9912-155.1215.1610"250mm56844448324387.516-291420370in22.3617.501.8912.7515.2516-1.12
