德国宝德两位三通先导阀体暗道通制动缸。二段阀轴向孔螺纹部分，配254rnm直径制动缸时拧上缩孔堵（Ⅷ），轴向孔下部两个径向孔，中部一个径向孔。二段阀弹簧室通列车管，二段阀上部O形密封圈防止制动管与制动缸之间窜气，二段阀下部空腔经阀体及缓解阀体通半自动缓解阀。二段阀下部密封圈在紧急制动二段作用时，密封副风缸向制动缸充气的大通路，限制制动缸压力上升速度，实现紧急制动时制动缸的变速充气作用。553223T 2031-A-2-080-FF-VS-TG40-D-C * 553224U SYST-2031-551858-1062-007472-551868 553225V SYST-2031-553223-1062-444938 553230E 3234-150-AB-B-VH-SA92-TI42-D050 * 553231T 2032-A-150-AB-B-VH-SA92-TI42-D-D * 553232U SYST-2032-553231-1060-701515 * 553233V SYST-3233-150-AB-SA92-TI42-004/04 * 553234W SYST-2031-1060-150-AB-TI42-004/04 * 553235X SYST-2731-3233-150-AB-TI42-004/04 * 553236Y SYST-2731-2031-150-AB-TI42-004/04 * 553238A 3233-2-0-250-EA-VG-SA60-D051 * 553239B 2031-A-2-250-EA-VG-SA60-D-F * 553240Q S03000-SA45-VAAA-P5-0-00-0-000/00-0* 553246A 601200-D012FBPA0000-2-024/DC-04 * 553253H KOMP-500-0311-4104-113-02-553253 * 553268Q 3233-2-0-080-EA-VS-TG42-D050 * 553269R 3233-2-0-080-EA-VS-TG42-D051 * 553282X 831100-TC46-VAFF-KZ-B-F1-2-BCV/DC-B* 553283Y S03000-SM25-PPFF-P5-0-00-0-000/00-0* 553292Z 2032-A-150-EA-B-VH-TI42-TI42-D-E * 553294T 2031-B-2-25553063W S03000-SA43-VAAA-P5-0-00-0-000/00-0* 553064X SE5500-0000-VC00-00-A-M1-3-BEQ/DC-3* 553065Y S051-060-16-GS83-VH-PT-FF-2-VH-3 553070H 3234-150-00-B-VH-TI42-TI42-0000 * 553071W 3234-200-00-B-VH-TI43-TI43-0000 * 553072X 3234-200-00-B-VH-SODH-TI43-0000 * 553073Y 3234-200-00-B-VH-SA64-TI43-0000 * 553074Z SYST-2031-441215-1062-552074 553075S SYST-2031-441321-1062-552075 553076T SYST-2031-443059-1062-552075 553077U SYST-2031-441364-1062-552075 553079E SYST-2731-553078-1067-449105 553081R SYST-2033-553080-1062-7473 553083K SYST-2033-553082-1062-7473 553084L 831400-GM82-VAFI-KZ-B-F1-2-BEN/DC-A* 553087P SYST-2033-553086-1062-007472 联系人：郑小姐
