The invention relates to the technical field of railway vehicle air braking, in particular to a slide valve device and an air control valve. The sliding valve device comprises a sliding valve seat and a sliding valve which can slide relatively in the first direction, a valve seat sealing face is arranged on the sliding valve seat, a sliding valve bottom face sealing face attached to the valve seat sealing face in a sealed mode is arranged on the sliding valve bottom face of the sliding valve, and corresponding valve ports are formed in the valve seat sealing face and the sliding valve bottom face sealing face. At least part of the valve seat sealing surface and/or the slide valve bottom surface sealing surface except the position of the valve port is provided with a foreign matter storage groove, and a part of the groove wall of the foreign matter storage groove forms a blocking wall used for blocking foreign matters when the slide valve bottom surface sealing surface and the valve seat sealing surface relatively move in the first direction. According to the sliding valve device, the sliding valve bottom face sealing face and the valve seat sealing face can be prevented from being abraded to be unqualified within a certain service cycle, and then the problem that a matching face between a sliding valve and a sliding valve seat of an existing sliding valve device is prone to being abraded is solved.

    本发明涉及铁道车辆空气制动技术领域,特别是涉及到了一种滑阀装置和空气控制阀。滑阀装置包括可沿第一方向相对滑动的滑阀座和滑阀,滑阀座上设有阀座密封面,滑阀的滑阀底面上设有与阀座密封面密封贴合的滑阀底面密封面,阀座密封面和滑阀底面密封面上设有对应的阀口,阀座密封面和/或滑阀底面密封面上于其阀口所在位置之外的至少局部设置有异物收储槽,异物收储槽的部分槽壁形成用于在滑阀底面密封面与阀座密封面沿第一方向相对运动时挡止异物的挡壁。本发明可避免滑阀底面密封面和阀座密封面在一定的使用周期内被磨损至不合格,进而解决了现有滑阀装置的滑阀与滑阀座之间的配合面易磨损的问题。
