产品详情衬氟隔膜阀引用标准：遵循GB/T12239，BS5156标准衬氟隔膜阀结构特点：1、复合隔膜将阀体下部内腔与阀盖内腔隔开，并与之形成直流通道，使隔膜上部的阀杆、阀瓣等内件与介质完全隔离，省去填料密封结构，介质的内漏和外漏可同时避免。2、做为执行元件的膜片由于频繁的启闭易产生疲劳断裂，应视工况、介质特性进行定期更换。3、塑料的防腐性能及推荐使用温度见“阀门及管路附件用塑料衬里性能表”。衬氟隔膜阀主要零件的材料说明：序号零件名称灰铸铁铸钢不锈耐酸铸钢超低碳不锈耐酸铸钢ZCPRPLPL1阀体/阀盖HT250WCBCF8CF8MCF3CF3M2阀瓣/阀杆351Cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo23衬里/阀座PCTEF(F3)、FEP(F46)、PFA（可溶性F4)、PP、PO4隔膜PEP(F46)/CR（氯丁橡胶）、PFA（可溶性F4)/FPDM（乙丙橡胶）5支架PTFE（F4)CF8CF86阀杆螺母ZCuAl10Fe3ZCuAl10Fe3ZCuAl10Fe37紧固螺栓351Cr17Ni21Cr18Ni9Ti8螺母450Cr18Ni90Cr18Ni99手轮WCBWCBWCB衬氟隔膜阀主要外形尺寸：公称通径标准值参考值DN(mm)NPS(inch)LDD1D2fbZ-φdWD0HWT(kg)PN0.6MPa151/21308055402124-φ12120801.6203/41309065502144-φ12120902.425114010075602144-φ121601003.43211/416512090702164-φ141601104.84011/2165130100803164-φ142001206.0502203140110903164-φ142501358.86521/22221601301103164-φ1425014511.58032411851501253184-φ1830018015.210043052051701453184-φ1830019518.812553562352001753208-φ1835021022.515063942602252003208-φ182004504820084573152802553228-φ18200490652501053337033531032412-φ18240550883001261043539536242412-φ232806001253501468648544541242612-φ232806751854001676253549546242816-φ233207802554501886459055051842816-φ233608203205002091464060056843016-φ23360910405)
