Z440Y-16I|Z440Y-25I|Z440Y-64I|Z440Y-100I伞齿轮闸阀闸阀又称闸板阀或闸门阀，应用最广泛的一种阀门。它是通过闸板的升降来控制阀门的启闭，闸板垂直于流体方向，改变闸板与阀座间相对位置即可改变通道大小。闸阀具有以下优点：1、流体阻力小,密封面受介质的忡刷和侵蚀小。2、开闭较省力。3、介质流向不受限制,不扰流、不降低压力。4、形体简单,结构长度短，制造工艺性好，适用范围广。主要性能规范CapabilityCriterion型号公称压力PN(MPa)试验压力ps(MPa)适用介质工作温度(℃)强度密封(液)低压密封(气)Z441H-252.53.82.80.6水、蒸汽、油≤400Z441H-404.06.04.40.6≤450Z441Y-40I4.06.04.40.6≤550Z441Y-40P4.06.04.40.6酸、碱类≤200Z441H-646.49.67.00.6水、蒸汽、油≤450Z441Y-64IGZ441Y-64I6.49.67.00.6≤550KZ441Y-646.49.67.00.6酸性天然气≤130Z441H-100Z441Y-10010.015.011.00.6水、蒸汽、油≤450Z441Y-100I10.015.011.00.6≤530主要零件材料MaterialsOfmainParts零件名称阀体、阀盖闸板阀杆阀杆螺母填料手轮Z441H-25Z441H-40Z441H-64Z441H-100碳钢碳钢不锈钢优质碳钢铝铁青铜石墨石棉绳、柔性石墨可锻铸铁Z441Y-100优质碳钢堆焊硬质合金KZ441Y-64318钢聚四氟乙烯Z441Y-40IZ441Y-64IGZ441Y-64I铬钼钢铬镍钛钢堆焊硬质合金铬硅钼钢耐高温石棉绳Z441Y-100I柔性石墨Z441Y-40P铬镍钛钢铬镍钛钢铬镍钢浸聚四氟乙烯石棉绳主要外型尺寸MainouterSize通径PN2.5MPaLDD1D2D6bZ-dH0HH1D0kg300500485430390-4016-30123611451474450451400600610550505-4816-34154014501886500998主要外型尺寸MainouterSize通径PN4.0MPaLDD1D2D6bZ-dH0HH1D0kg3007505104504083644616-341234117514754506103508505705104654225216-341377132216785008904009506555855354745816-41155214921900560133350011507556706125766220-482135197525107202526主要外型尺寸MainouterSize通径PN6.4MPaLDD1D2D6bZ-dH0HH1D0kg3007505304604123645416-411308122015405006183508505955254754226016-411565146918505609454009506705855254746616-48178516402080640181850011508007056405767020-54213519752510720250760013509308207506787620-582295242529598003352主要外型尺寸MainouterSize通径PN10.0MPaLDD1D2D6bZ-dH0HH1D0kg1504503502902502044612-348387759523603012005504303603122605412-41102298012164005792256004704003522875612-411167105112025006462506505004303823136012-411167110813775506873007505855004423647016-4814311324158256011783508506555604984227616-541574144818386401174上海维旺迪阀门有限公司：http:///products/01/ml上海维旺迪阀门：http:///product/fangzhen/2011-05-11/ml)
