The invention belongs to the technical field of brake valves, and particularly relates to a wear-resistant action part for a railway vehicle brake valve. According to the technical scheme, the abrasion-resistant action part for the railway vehicle brake valve comprises a main piston rod, a control valve and a sliding valve are connected to the main piston rod, the control valve is in sliding contact with one side of the sliding valve, the abrasion-resistant action part further comprises a sliding valve sleeve, the main piston rod and the sliding valve are arranged in the sliding valve sleeve, and the side, away from the control valve, of the sliding valve is in sliding contact with the sliding valve sleeve; the sliding valve comprises a plurality of layers of split structures which are fixedly connected, the adjacent split structures are split from the positions, where the transverse holes are formed, of the sliding valve, and the transverse holes are closed in the transverse direction of the sliding valve. The invention provides the wear-resistant action part for the railway vehicle brake valve, which can avoid leakage.

    本发明属于制动阀技术领域,特别涉及一种铁路车辆制动阀用耐磨作用部。其技术方案为:一种铁路车辆制动阀用耐磨作用部,包括主活塞杆,主活塞杆上连接有节制阀和滑阀,节制阀和滑阀的一侧滑动接触,还包括滑阀套,主活塞杆和滑阀设于滑阀套内,滑阀远离节制阀的一侧与滑阀套滑动接触;所述滑阀包括固定连接的若干层分体结构,相邻分体结构从滑阀设置横向孔的位置剖分,横向孔在滑阀的横向上封闭。本发明提供了一种避免泄漏的铁路车辆制动阀用耐磨作用部。
