The invention relates to the technical field of braking equipment and discloses an angle cock for train braking. The angle cock for train braking comprises a cock body, wherein one side of the cock body is integrally molded with a vertically arranged body, and an inner cavity of the cock body and the vertically arranged body are matched and intersected to form a fixed sleeve which is provided with a sealing seat. According to the angle cock for train braking, airflow generated in the train running process of a fan drives a rotating shaft to rotate to drive a magnet disc to rotate, a first thread cuts a magnetic field of the magnet disc to generate eddy current to generate heat, heat is conducted to the top of a plug plate, an air bag is heated and expanded to drive the plug plate to move downwards, and an axial through hole of a sealing seat can be opened; when the cock is forgotten to be opened before a train is started, the cock can be automatically opened, a heat conduction rod moves downwards to drive a protruding block to be matched with a braking groove, a first thread is meshed with a second thread, an air bag is cooled and contracted, the heat conduction rod is limited by the braking groove, and under the elastic force effect of a first spring, a plug plate cannot rise and is automatically closed; it is guaranteed that the cock can be kept open in the train running process.

    本发明涉及制动装备技术领域,且公开了一种列车制动用折角塞门,包括塞体,所述塞体的一侧一体成型有上下方向设置的竖装体,所述塞体的内腔且与竖装体的配合交汇出固定套装有密封座。该列车制动用折角塞门,通过风扇在列车行驶过程中的气流带动转轴转动带动磁石盘转动,螺纹一切割磁石盘的磁场产生涡流生热,热量传导到塞板的顶部,气囊受热膨胀带动塞板下移,可将密封座的轴向通孔打开,完成列车在开车前忘记打开塞门时,能够自动打开,且导热杆下移带动凸块与制动槽配合,螺纹一与螺纹二啮合后,气囊降温后收缩后,导热杆被制动槽限位,在弹簧一的弹力作用下,塞板不会上升自动关闭,保证列车行车过程中塞门是能够保持开启的。
