Z43WFM无导流孔平板闸阀概述：无导流孔平板闸阀适用于天然气，石油，化工，环保，城市管道，燃气管线等输送管线，放空系统和汽储存装置上，用作启闭设备。适用于天然气开采和净化的长输管线。Z43WFM无导流孔平板闸阀的特点：1.阀座的密封结构应为弹性有预紧力，上、下游密封座同时密封的结构。阀座与密封物间始终为面对面密封。2.阀座有自清洗功能，并且在阀门开启或关闭过程中不受气流的直接冲刷。阀座应由有润滑、不磨损材料制成。3.阀门执行机构的故障不会影响到阀门的其它部分，维修和更换工作能够在不拆下阀门的情况下进行。(1)轭架套管–铝青铜轭架套管配置针形止推轴承，最大程度减少操作扭矩。(2)阀杆–螺纹长度直到托架；销钉和点焊；具有稳定性。(3)压力密封–结构简单，配置分段扣环和镀银低碳钢垫圈，有助于拆卸和实现最好的阀帽密封。(4)阀座环–焊接阀座环垂直于流动通道，易于维护。(5)执行机构–这些阀门可以配置电动、液动或气动执行机构。DN300以下配置标准手动手轮，DN350以上配置斜齿轮操作机构。(6)轭架–完全装配式轭架通过抗震测试，易于维护和安装执行机构。(7)压盖–两件式，自调节压盖，避免被弹出。(8)整体后座–硬面，使用寿命最长。(9)阀瓣–弹簧负载阀瓣能够自行调节，减少执行机构的扭矩需求。(10)整体止动–整体铸造托架止动装置，定位组装的托架阀瓣，使得阀座更加稳定可靠。Z43WFM无导流孔平板闸阀执行标准：设计规范结构长度连接法兰试验与检验压力-温度产品标识JB/T5298JB/T5298JB/79JB/T5298GB9131GB/T12220API6DAPI6DANSI-16.5API6DANSIB16.34MSSSP-25Z43WFM无导流孔平板闸阀产口性能规范：设计等级常温下试验压力（MPa）适用温度℃适用介质壳体左密封左密封低压密封“G”型“D”型普通型“抗硫”型“基本”型公称压力PN（MPa）1.62.41.761.760.6-29～50-45～21-2～121H2S和CO2总含量大于500mg/m2的介质石油天然气、水等2.53.752.752.750.64.06.04.44.40.66.49.67.047.040.6磅级Lb1503.02.22.20.63007.75.65.60.6平板闸阀主要零部件材料：阀门/阀盖WCBWC6A352-LCBA351-CF8M闸板2Cr13+ENP20CrMoV+STLANSO410+ENPANSI316+ENP阀杆2Cr132Cr13A182-A6aA182-A316S阀座25+PTFE20CrMoV+STLA105+PTFEA182-F316+PTFE填料NBR/FPM柔性石墨/FlexibleGraphite聚四氟乙烯/PTFE+FPM垫片-螺栓3535CrMoA193-B7MA193-B8适用介质水、油口、蒸汽蒸汽、油品丙烷、乙烯硝酸类平板闸阀主要外形和连接尺寸PN1.6MPa-2.5MPa：1.6MPaDNLDD1D2DofbHH1n-Φd凸面法法RF(K)Z43WF-16C(K)Z543WF-16C(K)Z643WF-16C(K)Z943WF-16C50178160125100250316584804-Φ1865190180145120250318634954-Φ18802031951601352503206881008-Φ181002292151811553003208631148-Φ181252542452101853503229401328-Φ1815026728024021035032410301508-Φ23200292335295265350326127716812-Φ23250330405355320400330149120312-Φ25300356460410375450430170123712-Φ25350381520470435500434187526516-Φ30400406580525485305436218030016-Φ30450432640585545305440244032520-Φ34500457705650608305444286036020-Φ41600508840770718305548345042520-Φ41700610910840788305550396046024-Φ418006601020950898305552455051224-Φ4190071111201050998250554525056528-Φ481000811125011701110250556587063028-Φ182.5MPa50178160125100250320584804-Φ18凸面法法RF(K)Z43WF-25(K)Z543WF-25(K)Z643WF-25(K)Z943WF-2565190180145120300322634958-Φ1880203195160135350322,3881008-Φ181002292301901603503248631148-Φ23125254270220188,3503289401328-Φ2515026730025021840033010301508-Φ25200292360310278450334127716812-Φ25250330425370332500336149120312-Φ30300356485430390305440170123716-Φ30350381550490448305444187526516-Φ34400406610550505305448218030016-Φ34450432660600555305450244032520-Φ34500457730660610305452286036020-Φ41600508840770718305556345042520-Φ41700610955875815305560396046024-Φ488006601070990930305564455051224-Φ48900711118010901025-566525059528-Φ541000811130512101140-568587066028-Φ48无导流孔平板闸阀PN4.0MPa-10.0MPa：4.0MPaDNLDD1D2YDoff2bHH1n-Φd凹凸法法MFM(K)Z43WF-40(K)Z543WF-40(K)Z643WF-40(K)Z943WF-4050250160125100882503420584804-Φ18652801801451201102503422634958-Φ188031019516013512125034226791028-Φ1810035023019016015030034.5248631158-Φ2312540027022018817635034.5289401338-Φ2515045030025021820435034.53010401528-Φ2520055037532028226035034.538128218812-Φ3025065044538534531340034.542149522312-Φ3430075041545040836445044.546170125016-Φ343508504705104654225004552188028016-Φ344009506555855354743054558220031020-Φ4145010506806105605243054560248033520-Φ4150011507556706125763054562289038020-Φ4860013508907957306783055662248045020-Φ5470014509959008357683055668398550024-Φ548001650113510309608763055676475057024-Φ586.4MPa50250175135105882503426584904-Φ23凹凸法法MFM(K)Z43WF-64(K)Z543WF-64(K)Z643WF-64(K)Z943WF-646528020016013011025034286341058-Φ238031021017014012125034306791108-Φ2310035025020016815030034.5327631308-Φ2512540029520217635034.5369701508-Φ30-15045034028024020435034.53810381758-Φ3420050040534530026035034.544128221012-Φ3425065047040035231340034.5481495240
