一、J941F电动衬氟截止阀概述截止阀是指关闭件(阀瓣)由阀杆带动并沿阀座中心轴线做升降运动的阀门，在管路上主要用来做接通或截断管路中的介质，但不能做节流用。J941F电动衬氟截止阀基本结构：1.氟塑料衬里J41F46型直通式、J45F46直流式、J44F46型角式截止阀，具有结构紧凑、启闭灵活、耐腐蚀性能强，行程短(一般为公称通径1/4)等项优点，被广泛应用在石油、化工等管路系统中做截断介质用，但需要强调的是氟塑料衬里的截止阀严禁用做流量调节，以免节流口处产生的高速介质流冲蚀破坏密封面。2.阀瓣与阀杆设计为一体结构，用以防止由于管路压力波动造成内件冲出阀体的可能性，结构紧凑，使用安全。二、J941F电动衬氟截止阀设计规范遵循规范STANDARD设计与制造GB12238/GB12235结构长度GB12221(长—短系列)法兰尺寸JB78/JB79(GB.HG.SH)压力试验GB/T13927标志GB12220供货/td>GB/T12252部件列表：1.阀体2.阀盖3.阀体衬里4.阀瓣5.压盖子6.连接板7.阀杆8.电动装置三、J941F电动衬氟截止阀主要零件材料/h2>零件名称灰铸铁铸钢不锈刚超低碳不锈钢ZCPRPLRL阀体、阀盖HT250/WCBWCBCF8CF8MCF3CF3M阀瓣、阀杆351Cr131Cr18Ni91Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo2活街螺栓35351Cr17Ni21Cr17Ni21Cr17Ni21Cr17Ni2衬里层/阀座FEP(F46)PCTFE(F3)PFA(可溶性聚四氟乙烯)填料PTFE(F4)PTFE(F4)填料压盖WCBWCBCF8CF8MCF3CF3M阀杆螺母ZCuAl10Fe3ZCuAl10Fe3蝶栓35351Cr17Ni21Cr17Ni21Cr18Ni9Ti1Cr18Ni9Ti螺母45450Cr18Ni90Cr18Ni90Cr18Ni90Cr18Ni9手轮HT200HT200WCCWCCWCCWCC四、J941F电动衬氟截止阀主要连接尺寸及重量公称通径标准值参考值DN(mm)NPS(inch)LDD1D2fbZ-φdD0H1H2W(kg)PN1.0(MPa)151/21309565452144-φ141002352607203/415010575552164-φ141002402657.525116011585652164-φ1412024527083211/4180135100782184-φ18140255285124011/2200145110853184-φ18140285315145022301601251003204-φ18160295330196521/22901801451203204-φ18180350395278033101951601353224-φ182403954454210043502151801553228-φ182404504905012554002452101853248-φ182805255556415064802802402103248-φ233206056458520084953352952653268-φ233606457651052501062239035032032812-φ234006858051353001269844040036842812-φ234007108141553501478750046042843016-φ23450750855320PN1.6(MPa)151/21309565452144-φ141002402657203/415010575552164-φ141002452707.625116011585652164-φ141202502758.23211/4180135100782184-φ18140260290124011/2200145110853184-φ18140285325145022301601251003204-φ18160300335186521/22901801451203204-φ18180355400268033101951601353228-φ182404004504010043502151801553248-φ182404554955012554002452101853268-φ182805305606515064802802402103288-φ2332060565085200849533529526533012-φ233606507701502501062240535532033212-φ254006908102453001269846041037543412-φ25400730845295PN2.5(MPa)151/21309565452164-φ141202402707.5203/415010575552164-φ14120245275825116011585652164-φ1414025029093211/4180135100782184-φ18160260325134011/2200145110852184-φ18180285335155022301601251003204-φ18180300335206521/22901801451203228-φ18240355400288033101951601353228-φ182804004504210043502301801603248-φ233204554955712554002702101883288-φ253205605607115064803002402183308-φ2536061065090)
