产品简介　　流体阻力小，球阀是所有阀类中流体阻力最小的一种，即使是缩径球阀，其流体阻力也相当小。　　2，开关迅速，方便，只要阀杆转动90°，球阀就完成了全开或全关动作，很容易实现快速启闭。　　3，密封性能好。球阀阀座密封圈一般采用聚四氟乙烯等弹性材料制造，易于保证密封，而且球阀的密封力随着介质压力的增加而增大。　　4，阀杆密封可靠。球阀启闭时阀杆只作旋转运动，因此阀杆的填料密封不易被破坏，而且阀杆倒密封的密封力随着介质压力的增加而增大。　　5，球阀的启闭只做90°转动，故容易实现自动化控制和远距离控制，球阀可配置气动装置，电动装置，液动装置，气液联动装置或电液联动装置。　　6，球阀通道平整光滑，不易沉积介质，可以进行管线通球。 客服 QQ：200952114球阀,浮动球阀,美标浮动球阀,日标浮动球阀,美标软密封浮动球阀,日标软密封浮动球阀 一、日标球阀产品性能规范 公称压力PN1.62.54.06.4壳体试验压力2.43.86.09.6密封试验液1.825.84.47.0密封试验气0.5~0.7适用介质　C　　　　　　P　　　　 R水、油品、蒸汽　　　硝酸类　　醋酸类适用温度≤200  二、日标球阀主要堆零件材料名称WCB类CF8类CF3类CF8M类CF3M类阀体左体A216-WCBA315-CFBA35-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/NYLIN阀座支承圈A105-1025A182-F304A182-F304LA182-F316A182-F316L弹簧 3yc-7/17-49HO型圈NBR氟橡胶螺柱A193-B7A193-B8螺母A194-2HA194-8 三、10K主要连接及重量尺寸inch1/2″3/4″1″1-1/2″2″2-1/2″3″4″5″6″8″10″DN1520254506580100125150200250Lmm108117127165178190203229356394457533Hmm59637597107142152178252272342345Wmm1301301602302304004007001100110015001500重量㎏2.33.04.57.09.515.019.033.058.093.0160.0200.0四、20K主要连接尺寸及重量尺寸inch1/23/411-1/222-1/23456810DN1520254506580100125150200250Lmm140152165190216241283305381403502568Hmm59637597107142152178252272342345Wmm1301301602302304004007001100110015001500重量㎏2.53.55.510.514.523.530.055.081.0118.0200.0250.0 五、150Lb外形尺寸和连尺寸公称通径单位LDTGCn-ΦdWHinmm1/2″15㎜10889123560.54-1511572in4.253.50.471.382.384-0.594.5328.33/4″20㎜117981243704-1511576in4.613.860.4723.134-0.595.93.621″25㎜127108125179.54-1515092in54.250.4723.134-0.595.93.621-1/2″40㎜16512714.37389.54-16200123in6.550.562.883.884-0.627.874.842″50㎜17815215.992120.54-19200132in76.000.6253.624.754-0.757.875.202-1/2″65㎜19017817.5105139.54-19320164in7.570.691.125.504-0.7512.66.453″80㎜20319019.1127152.44-19320173in87.500.75564-0.7512.68.64″100㎜22922923.9157190.54-19450210in990.946.197.54-0.7517.728.266″150㎜39427926216241.58-228000288in15.510.981.028.59.508-0.8831.51.348″200㎜45734329270298.58-221120374in18.0013.501.1210.6211.758-0.8844.1014.7210″250㎜5334063132436212-251420366in20.98161.212.7514.7512-155.1214.4012″300㎜6104833238143212-251420412in24191.26151712-155.1216.22 六、300Lb外形尺寸和连接尺寸公称通径单位LDTGCn-ΦdWHinmm1/2″15㎜14095153566.54-1511572in5.513.740.591.382.624-0.594.5328.33/4″20㎜152117164382.54-1911576in5.984.610.621.693.254-0.754.5329.91″25㎜1651241851894-1915092in6.54.90.7123.54-0.755.93.621-1/2″40㎜19015620.773114.54-22200123in7.56.120.812.884.514-0.887.874.842″50㎜21616522.3921278-19200132in8.56.50.883.6258-0.757.875.202-1/2″65㎜24119025.41051498-22320164in9.57.514.125.878-0.8812.66.453″80㎜28321028.5127168.58-22320173in11.258.25101256.628-0.8812.66.84″100㎜30525431.81572008-22450210in12101.256.197.888-0.8817.728.266″150㎜40331836.621627012-221120336in15.87512.51.448.510.6212-0.8844.1013.238″200㎜5023814227033012-251420385in19.761516.510.6212.9912-155.1215.1610″250㎜56844448324387.516-291420370in22.3617.501.8912.7515.2516-1.1255.1214.56
