低温闸阀 闸阀是较常用的截断阀之一,主要用来接通或截断管路中的介质,不适用于调节介质流量。闸阀适用的压力、温度及口径范围很大,尤其适用于中、大口径的管道。 闸阀的主要优点: (1)流体阻力小。闸阀闸体内部介质通道是直通的,介质流经闸阀时不改变其流动方向,因而流动阻力较小。 (2)启闭较省力。启闭时闸板运动方向与介质流动方向相垂直。与截止阀相比,闸阀的启闭较为省力。 (3)介质流动方向一般不受限制。介质可从闸阀两侧任意方向流过,均能达到接通或截断的目的。便于安装,适用于介质的流动方向可能改变的管路中。 主要零件材料及性能规范 主要零部件 阀体 阀盖 碳钢 铬镍钛不锈钢 铬镍钼钛不锈钢 **低碳不锈钢 铬钼合金钢 低温碳钢 闸板 阀座 碳钢堆焊硬质合金或不锈钢 铬镍钛不锈钢 堆焊硬质合金 铬镍钼钛不锈钢 堆焊硬质合金 **低碳不锈钢 铬钼合金钢 堆焊硬质合金 不锈钢堆焊硬质合金 阀杆 铬不锈钢 铬镍钛不锈钢 铬镍钼钛不锈钢 **低碳不锈钢 铬钼合金钢 不锈钢 填料 石墨石棉盘根 浸聚四氟乙烯石棉盘根 柔性石墨石棉盘根 浸聚四氟乙烯石棉盘根 垫片 石棉垫片 不锈钢带四氟乙烯缠绕垫片 柔性石墨+不锈钢 聚四氟乙烯 阀杆螺母 高镍球铁/ZguAL10Fe3 主要参数 适用介质 水、蒸汽、油品 硝酸类 醋酸类 尿素、甲铵液等 水、蒸汽、石油及石油产品 氨气、液氨 适用温度℃ ≤425 ≤200 ≤200 ≤200 ≤550 -45~150 型号 公称 主要结构尺寸(mm) 阀体 材料 性能规范 通径 DN(mm) 压力 PN(MPa) D D0 L H 适用温度(℃) 适用介质 SFD46Z-40C150C 1/2" 150 89 140 108 345 LCB ≥-46 NH3、丙烷 " 3/4" " 98 150 117 355 " " " " 1" " 108 150 127 454 " " " " 2" " 152 200 178 481 " " " " 3" " 190 230 203 574 " " " " 4" " 229 280 229 708 " " " " 6" " 279 330 267 946 " " " " 8" " 343 380 292 1118 " " " " 10" " 406 460 330 1312 " " " " 12" " 483 510 356 1547 " " " " 14" " 533 560 381 1811 " " " " 16" " 597 560 406 2002 " " " " 18" " 635 610 432 2256 " " " " 20" " 698 760 457 2532 " " " " 24" " 813 810 508 3000 " " " SFD101Z-40C150C 1/2" 150 89 140 108 405 LC3 ≥-101 乙烯等 " 3/4" " 98 150 117 415 " " " " 1" " 108 150 127 514 " " " " 2" " 152 200 178 591 " " " " 3" " 190 230 203 634 " " " " 4" " 229 280 229 768 " " " " 6" " 279 330 267 1006 " " " " 8" " 343 380 292 1128 " " " " 10" " 406 460 330 1372 " " " " 12" " 483 510 356 1607 " " " " 14" " 533 560 381 1871 " " " " 16" " 597 560 406 2062 " " " " 18" " 635 610 432 2316 " " " " 20" " 698 760 457 2592 " " " " 24" " 813 810 508 3060 " " " SFD196Z-40C150P 1/2" 150 89 140 108 405 ZGOCr18Ni9 ≥-196 液氨、乙烯、液化天然气等 " 3/4" " 98 150 117 415 " " " " 1" " 108 150 127 514 " " " " 2" " 152 200 178 591 " " " " 3" " 190 230 203 634 " " " " 4" " 229 280 229 768 " " " " 6" " 279 330 267 1006 " " " " 8" " 343 380 292 1128 " " " " 10" " 406 460 330 1372 " " " " 12" " 483 510 356 1607 " " " " 14" " 533 560 381 1871 " " "
