The anti-skid exhaust valve for the rail transit vehicle comprises a valve body, a first cover plate and a second cover plate, a mounting groove is defined by the first end of the valve body, the first cover plate and the second cover plate, and an exhaust electromagnetic valve and a pressure maintaining electromagnetic valve are mounted in the mounting groove. A first electromagnetic coil of the air exhaust electromagnetic valve and a second electromagnetic coil of the pressure maintaining electromagnetic valve are clamped and pressed between the first cover plate and the second cover plate, and the two sides of the first electromagnetic coil and the two sides of the second electromagnetic coil are connected with the first cover plate and the second cover plate through bearing pins. Or the first electromagnetic coil and the second electromagnetic coil are connected with the valve main body through bearing pins. According to the anti-skid exhaust valve for the rail transit vehicle, the movable iron core structure and the static iron core structure in the electromagnetic valve can be effectively protected, and driving safety is better facilitated.
本发明为一种轨道交通车辆用防滑排风阀,包括阀主体、第一盖板和第二盖板,阀主体的第一端与第一盖板和第二盖板之间围合形成一安装槽,在安装槽内安装有排风电磁阀和保压电磁阀。排风电磁阀的第一电磁线圈和保压电磁阀的第二电磁线圈均卡压在第一盖板和第二盖板之间,且第一电磁线圈的两侧和第二电磁线圈的两侧均通过承载销钉与第一盖板和第二盖板连接,或者第一电磁线圈和第二电磁线圈均通过承载销钉与阀主体连接。本发明中的轨道交通车辆用防滑排风阀能有效对电磁阀中的动静铁芯结构进行保护,更有助于行车安全。
