The invention provides a slide valve device, and relates to the technical field of railway vehicle air braking. Comprising a sliding valve seat and a valve sleeve, the sliding valve seat comprises a first sealing piece and a seat body, and the first sealing piece is in sealing connection with one side of the seat body; a sliding groove is formed in the inner hole wall of the valve sleeve, a second sealing piece is arranged on the bottom face of the sliding groove in a sealed mode, the side, away from the base body, of the first sealing piece can be attached to the side face of the second sealing piece, a first valve port set is arranged on the first sealing piece, and a second valve port set corresponding to the first valve port set is arranged on the second sealing piece in a penetrating mode. A gas path group is arranged in the seat body in a penetrating manner; the first valve port group is communicated with the gas path group; the first sealing piece and the second sealing piece are made of high-strength wear-resistant materials. Due to the fact that the first sealing piece and the second sealing piece are large in hardness and excellent in abrasion resistance, foreign matter is not prone to abrading the first sealing piece and the second sealing piece, the sealing performance between the first sealing piece and the second sealing piece is guaranteed, and the service life of the sliding valve device is prolonged by more than ten times.

    本发明提出了一种滑阀装置,涉及铁道车辆空气制动技术领域。包括滑阀座和阀套,滑阀座包括第一密封件和座体,第一密封件与座体的一侧密封连接;阀套的内孔壁上开设有滑槽,滑槽的底面上密封设置有第二密封件,第一密封件远离座体的一侧能够与第二密封件的侧面贴合,在第一密封件上设有第一阀口组,在第二密封件上穿设有与第一阀口组对应的第二阀口组;座体内部穿设有气路组,第一阀口组和气路组连通;第一密封件和第二密封件均为高强耐磨材质。由于第一密封件和第二密封件硬度大、‌耐磨性能极好,异物不易对第一密封件和第二密封件造成磨损,从而保证了第一密封件和第二密封件之间的密封性,使滑阀装置的使用寿命提高十倍以上。
