产品结构特点：1、手动部分可采用钢板压制的手柄或不锈钢铸造的手柄。手柄设有限位结构，在阀门开启、关闭的位置设定限位，当阀门使用在关键装置上时，限位块上设有锁孔可锁定开关位置避免误操作。手柄上有明显地开和关标识。2、阀杆采用A182F（1Cr13）整体锻造并调制处理，硬度达到HB220～250。阀杆通过平键或花键或方契与手柄连接，通用性强，拆装方便。阀杆设有防吹出结构。3、阀门的填料选用编结、柔性石墨密封圈或四氟烯密封圈，使得阀杆在一定的润滑情况下实现可靠的密封。4、根据需要，球阀可设计成防静电结构，在球体与阀杆、阀杆与阀体之间设置导电弹簧，避免静电打火点燃易燃物质，确保系统安全。5、密封副形式多样。根据不同工况可选用软密封、硬密封、防火阀座等结构；DN150以下为浮球形式，DN200以下为固定球形式。6、球阀阀座处可设置辅助密封结构，在阀座和阀杆部位加装注脂阀，紧急情况下可暂时密封，并可根据需要加长阀杆以适宜埋地铺设得场所。主要性能规范型号试验压力ps(MPa)工作温度(℃)适用介质壳体密封(液)密封(气)Q947F-101.5PN1.1PN0.6MPa-29-200(加玻纤增强聚四氟乙烯)、-29-300(对位聚苯)水、蒸汽、油品等Q947F-16硝酸等腐蚀性介质强氧化性介质Q947F-25Q947F-64醋酸等腐蚀性介质Q947F-160尿素等腐蚀性介质主要零件材料阀体球体、阀杆阀座WCB2Cr13加玻纤增强聚四氟乙烯、对位聚苯ZG1Cr18Ni9Ti1Cr18Ni9Ti加玻纤增强聚四氟乙烯、对位聚苯CF80Cr19Ni9-(304)加玻纤增强聚四氟乙烯、对位聚苯CF300Cr19Ni11-(304L)加玻纤增强聚四氟乙烯、对位聚苯ZG1Cr18Ni-12Mo2Ti1Cr18Ni12-Mo2Ti加玻纤增强聚四氟乙烯、对位聚苯CF8M0Cr17Ni12-Mo2(316)加玻纤增强聚四氟乙烯、对位聚苯CF3M00Cr17Ni14-Mo2(316l)加玻纤增强聚四氟乙烯、对位聚苯主要外型尺寸PN1.0(MPa)通径(DN)Ld1DD1D2bZ-dH重量125356125245210185228-18520100150394150280240210228-23538165200457200335295265248-235802292505332503903503202612-236372653006103004404003682612-236843933506863505004604282616-237965144007624005655154822616-258427654508644506155655322820-258749305009145006706205852820-259041210PN1.6(MPa)通径(DN)Ld1DD1D2bZ-dH重量125356125245210185228-18520105150394150280240210248-235381702004572003352952652612-235802342505332504053553203012-256372753006103004604103753012-256844033506863505204704353416-257965344007624005805254853616-308427854508644506405855454020-308749605009145007056506084420-349041250PN2.5(MPa)通径(DN)Ld1DD1D2bZ-dH重量100305100230190160248-2347085125381125270220188288-25520117150403150300250218308-255381802005022003603102783412-255802462505682504253703323612-306373003006483004854303904016-306844443507623505504904484416-347965864008384006105505054816-348428604509144506606005555020-3487410735009915007306606105220-419041315PN6.4(MPa)通径(DN)Ld1DD1D2D6bZ-dH重量502925017513510588264-23380506533065200160130110288-23424658035680210170140121308-2343480100432100250200168150328-25456111125508125295240202176368-30525170150559150340280240204388-345542202006602004053453002604412-345942902507872504704003523134812-417045003008383005304604123645416-417317103508893505955254754226016-4178610304009914006705855254746616-488671350PN16.0(MPa)通径(DN)Ld1DD1D2D6bZ-dH重量503685021516513288368-25-826541965245190152110448-30-1258038180260205168121468-30-160100457100300240200150488-34-210125-125355285238176608-41-2701506101503903182702046612-41-3502007372004804003452607812-48-5802508382505804854253138812-54-87030096530066557051036410016-54-1350)
