衬里隔膜阀结构特点1.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；2.利用FEP(Teflon)氟塑料与全成橡胶复合而成的隔膜的带有Teflon氟塑料衬里层的阀门，可适于除“熔融碱金属、元素氟”外的各种强腐蚀性介质。3.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、介质的特性，进行定期更换。4.氟塑料的防腐性能及推荐使用温度风“阀门及管路附件用氟塑料衬里性能表”。阀体材质A216WCBA351CF8A351CF3A351CF8MA351CF3MWCB304304L316316L技术性能规范设计标准HG/T3704、GB/T12239MSS-SF-88结构长度HG/T3704、GB/T12221A***EB16.10、JISB2220法兰标准HG/T20592、GB/T9119A***EB16.5检验与试验HG/T13927、GB/T9092API598公称压力≤1.6MPa150LB衬里材料手动手轮气动电动G41F4G641F4G941F4G41FEPG641FEPG941FEPG41F46G641F46G941F46G41PFAG641PFAG941PFAG41FPAG641FPAG941FPAG41FAG641FAG941FAG41POG641POG941POG41F3G641F3G941F3G41F2G641F2G941F2G41F40G641F40G941F40)
