耐腐蚀衬氟隔膜阀基本系列为全衬里G41F46、EG41F46、型堰式和G45F46型直流式。复合隔膜阀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。表面均匀包覆一层FEP。阀体通道内表面光滑,流体阻力小,CV值高,流通能力强,扭矩适中,采用四级密封结构并在密封面外配以耐温抗老化的SI橡胶的弹性衬垫阀座,完全达到介质的零泄漏。基本型号手动G41F3直流式G45F3G41F46G45F46气动Q641F3电动Q941F3Q641F46Q941F46主要零部件材料表序号零件名称灰铸铁铸钢不锈耐酸铸钢超低不锈钢耐酸铸钢ZCPRPR1阀体/阀盖HT250WCBCF8CF8MCF3CF3M2阀瓣/阀杆351cr131Cr18Ni9Ti1Cr18Ni12Mo2Ti00cr18Ni1000Cr17Ni14Mo23衬里/阀座PTFE(F4)、PCTFE(F3)、FEP(F46)、PFA(可溶性F4)4隔膜FEP(F46)/CR(氯丁橡胶)、PFA（可溶性F4）/FPDM（乙丙橡胶）5支架WCBCF8CF86阀杆螺母ZCuAI10Fe3ZCuAI10Fe3ZCuAI10Fe37紧固螺栓351Cr17Ni21Cr18Ni9Ti8螺母450Cr18Ni90Cr18Ni99手轮WCBWCBWCB主要外型和连接尺寸公称通径标准值参考值DN(mm)NPS(inch)LDD1D2fbZ-фdd0HH1WT(kg)PN0.6MPa/PN1.0MPa151/21259565452144-ф141001051103.5203/413510575552164-ф14100115125425114511585652164-ф141201201355.53211/4160135100782184-ф1812012515084011/2180145110853184-ф18140135175115022101601251003204-ф18140155195146521/22501801451203204-ф18200170200238033001951601353224-ф182002002552910043502151801553228-ф182802703254612554002452101853248-ф183203354057015064602802402103248-ф233203704509520085703352952653268-ф234004806001702501068039035032032812-ф235005456202703001279043539536242412-ф23500585680320PN1.6MPa151/21309565452144-ф141201101154203/415010575552164-ф14120120130525116011585652164-ф1414012514063211/4180135100782184-ф1814013015594011/2200145110853184-ф18160140180125022301601251003204-ф18160160200156521/22901801451203204-ф1820017520524803310195160
