D371F46衬氟对夹式蝶阀概述D371F46-16衬氟对夹式蝶阀是用随阀杆一起转动的蝶板作启闭件,用以实现阀门的开启、关闭与调节。另外，蝶阀还有体积小、重量轻、结构简单等优点，与同参数闸阀比较，平均减轻重量达30～50%，蝶板旋转90°即可实现启、闭过程，又由于转轴两侧蝶板受介质作用力近似相等，转矩相反，因此启闭力矩较小。结构特点中线蝶阀为整个蝶板与阀座在360°圆周内同心(中线),具有双向密封功能,压力,流量可自由调节；四级加载弹性密封，绝对保证了阀门内、外的零泄漏；轴头、蝶板园周连接处的特殊过渡曲线与阀座的合理过盈；轴头端面采用弹性O型圈和轴肩处刚性垫圈、弹性橡胶垫组合；轴的径向采用O型圈与金属垫的组合；阀座镶在有弹性条的阀体的槽内；采用可调弹性弹子定位。定位准确，结构简单。D371F46衬氟对夹式蝶阀基本型号：手动DA71F/P半衬蜗轮传动DA371F/P半衬DA71F3全衬里DA371F3全衬里DA71F4全衬里DA371F4全衬里DA71F46全衬里DA371F46全衬里气动DA671F/P半衬电动DA971F/P半衬DA671F3全衬里DA971F3全衬里DA671F4全衬里DA971F4全衬里DA671F46全衬里DA971F46全衬里D371F46衬氟对夹式蝶阀主要零部件材料表：序号零件名称灰铸铁铸钢不锈钢超低碳不锈阀ZCPRPLRL1上，下阀体HT250WCBCF8CF8MCF3CF3M2蝶板WCB35(锻）CF8CF8MCF3CF3M3蝶板轴1Cr132Cr131Cr18Ni91Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo24衬里层/阀座PTFE(F4)、PCTFE(F3)、FEP(F46)、PFA(可溶性4)5O型圈FPM（氟橡胶）6弹性条（垫）Si（硅橡胶）7调节定位座0Cr18Ni90Cr18Ni91Cr18Ni91Cr18Ni12Mo2Ti00Cr18Ni1000Cr17Ni14Mo28螺栓351Cr17Ni21Cr18Ni9Ti9螺母450Cr18Ni90Cr18Ni910手轮Q235D371F46衬氟对夹式蝶阀技术规范：设计标准GB12238结构长度GB12221法兰标准JB/T79-94GB9113.1-26检验试验GB/T13927驱动方式蜗轮、手动、电动、气动D371F46衬氟对夹式蝶阀结构图D371F46衬氟对夹式蝶阀主要外型和连接尺寸公称通径标准值参考值DN（mm）NPS（inch）LDD1D2fbZ-ΦdDoHW(Kg)PN0.6Pa4011/233130100803164-Φ141601402.550243140110903164-Φ142001453.56521/2461601301103164-Φ142501554.5803461851501253184-Φ1825016561004522051701453184-Φ182501807.51255562352001753208-Φ18300203111506562602252003208-Φ18300225162008603152802553228-Φ18200*27548250106837033531032412-Φ18200*31560300127843539536242412-Φ23240*34875350147848544541242612-Φ23240*415824001610253549546242816-Φ23280*4601234501811459055051842816-Φ23280*5001505002012764060056843016-Φ23320*5301806002415475570567053020-Φ25320*6102257002816586081077553224-Φ25360*6753158003219097592088053424-Φ30360*805385900362031075102098053624-Φ30380*99542010004021611751120108053628-Φ30400*117062012004825414001340129554032-Φ34400*1295788公称通径标准值参考值DN（mm）NPS（inch）LDD1D2fbZ-ΦdDoHW(Kg)PN1.0MPa4011/233145110853184-Φ181601403502431601251003204-Φ1820014546521/2461801451203204-Φ182501556803461951601353224-Φ1825016581004522151801553228-Φ18300180121255562452101853248-Φ18300203181506562802402103248-Φ23200*225282008603352952653268-Φ23200*27556250106839035032032812-Φ23240*31572300127844040036842812-Φ23240*34888350147850046042843016-Φ23240*4151204001610256551548243216-Φ25280*4601454501811461556553243220-Φ25280*5001655002012767062058543420-Φ25320*5301956002415478072568553620-Φ30320*6102687002816589584080054024-Φ20360*67532080032190101095090554424-Φ34360*8053959003620311101050100554628-Φ34380*99545010004021612201160111555028-Φ34400*117068012004825414501380132555632-Φ41400*1295825公称通径标准值参考值DN（mm）NPS（inch）LDD1D2fbZ-ΦdDoHW(Kg)PN1.6Pa4011/233145110853184-Φ182001454502431601251003204-Φ1820015056521/2461801451203204-Φ182501607803461951601353228-Φ18250170101004522151801553248-Φ18300185141255562452101853268-Φ18300210221506562802402103288-Φ23200*2303220086033529526533012-Φ23240*28566250106840535532033212-Φ25240*32580300127846041037543412-Φ25280*36094350147852047043543816-Φ25280*4301254001610258052548544016-Φ30320*4751504501811464058554544420-Φ30320*52517250020
