衬氟闸阀结构特点：1.阀体有扁体和圆体两种形状：GB阀门采用圆体，ANSI磅级阀门DN≤300Lb采用扁体，DN≥400Lb采用圆体，阀体、阀盖的内腔和闸板、阀杆外表面等直接与介质接触的部件，全部名衬FEP（F46）等氟塑料；2.密封副为FPF（F46）/FEP（F46）或其它材料组合，摩擦系数小，启闭力矩低；3.填料采用PTFE（F4）标准填料，密封性能好，维修更换方便；4.带有弹性的闸板，可补偿闸板密封面与阀座密封面之间楔角偏差，吻合度好，密封效果理想；5.介质可从两侧任意方向通过闸阀，适用于介质方向可能改变的管路上作用启闭装置。衬氟闸阀性能规范：设计规范结构长度连接法兰试验与检验产品标识供货规范GB/T12233(GB/T12235)GB/T12221JB/T78;JB/T79GB/T13927GB/T12220JB/T7928衬氟闸阀零部件材料：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ZGPRPLPL1阀体/端盖HT250WCBCF8CF8MCF3CF3M2球体/阀杆1Cr132Cr131Cr18Ni91Cr18NI12Mo2TI00Cr18NI1000Cr17Ni14Mo23衬里/阀座PTFE(F4)、PCTFE(F3)、FEP(F46)、PFA(可溶性F4)4填料/压盖PTFE(F4)PTFE(F4)PTFE(F4)5填料351Cr17NI21Cr17Ni26活节螺栓ZCuA110Fa3ZCuA110Fa3ZCuA110Fa37阀杆螺母351Cr18Ni21Cr18Ni28紧固螺栓351Cr18Ni21Cr18Ni29螺母450Cr18NI90Cr18NI910手轮WCBWCBWCB衬氟闸阀规格尺寸表：公称通径标准值参考值DN(mm)NPS(inch)LDD1D21bz-φdDOHH1WT(kg)PN0.6MPa151/21308055402124-φ121001001205203/41509065502144-φ12100120140825116010075602144-φ1212013015073211/418012090702164-φ14120156185104011/2240130100803164-φ1416016520518502250140110903164-φ14160350400256521/22701601301103164-φ14180370435308032801851501253184-φ181804605104310043002051701453184-φ18220495595581255325352001753208-φ1822061073510018263502802252003208-φ1824067082011520084003152302253228-φ232408151015145250104507033531032412-φ2324096512152303001250043538536242412-φ23280114014403353501455048544541242612-φ23280127516255404001660053548546242816-φ23320144518456704501865059055051842816-φ23320153019807805002070064060056843016-φ2336017252225850PN1.0MPa151/21309565452144-φ141001101256203/415010575552164-φ14100120140725116011585652164-φ1412013215583211/4180135100782184-φ18120156185114011/2240145110853184-φ18160167210205022501601251003204-φ18160358410286521/22701801451203204-φ18180375440328032801951601353224-φ181804355154510043002151801553228-φ182205006006012553252452101853248-φ1822061574011015063502802402103248-φ2324067582512020084003352952653268-φ2328082010201502501045039035032032812-φ2332097012202403001250044040036842812-φ233201145144034035014550500046042843016-φ23360128016305504001660056551548243216-φ25400145018506804501865061556553243220-φ25500153819887955002070067062058543420-φ2550017302230880PN1.6MPa151/21309565452144-φ141201101307203/415010575552164-φ14120120140825116011585652164-φ1412013516093211/4180135100782184-φ18160160190134011/2240145110853184-φ18160170220255022501601251003204-φ18160360410326521/22701801451203204-φ18180380440388032801951601353228-φ181804405205010043002151801553248-φ182405006006812553252452101853268-φ1824061574012515063502802402103288-φ23280680830170200840033529526533012-φ2328082010202102501045040535532033212-φ2532096012302603001250046041037533412-φ25320115014504803501455052047043543816-φ25400128516356204001660058052548544016-φ25400145518558054501865064058554544416-φ30500154519908805002070070565060844620-φ3450017352235920PN2.5MPa151/21309565452164-φ141201101308203/415010575552164-φ14120130140925116011585652164-φ14160136160103211/4180135100782184-φ18160160190144011/2240145110853184-φ18180170220285022501601251003204-φ18180360410366521/22701801451203228-φ18240380440458032801951601353228-φ182404405205810043002301901603248-φ232805006007812553252702201883288-φ2528061574014315063603002502153308-φ25320680830178200840036031027833512-φ2532082010202432501045042527033233612-φ3040098012302753001250048543039044016-φ3040011501450520PN4.0MPa151/21309565462144-φ141602202409203/415010575562164-φ141802562801225116011585653164-φ14180275305143211/4180140100763184-φ18200285318164011/2200150110843184-φ1820032036529502250165125993204-φ18280371425336521/22801851451183228-φ18280393463468033102001601323248-φ183204554355310043502351901563248-φ183605516608012554002702201843268-φ2640063475512815064503002502113288-φ26400708860155200855037532028433412-φ3045085810602652501065045033531533812-φ33550101512703703001275051545040944216-φ3364012001580550)
