The invention discloses a side opening type electric pressure wave protection valve for a train, wherein the valve comprises a mounting bottom plate; two side plates are fixedly connected to the positions, close to the edges, of the two sides of the top face of the mounting bottom plate through a plurality of first hexagon screws correspondingly, two first shaft sleeves are fixedly connected to the sides, close to each other, of the two side plates correspondingly, and a shaft rod is rotationally connected between the two first shaft sleeves; and the shaft rod is fixedly connected with the top face of one side of a movable plate through a plurality of second hexagon screws, two supporting plates are vertically and fixedly connected with the two sides of the top face of the mounting bottom plate correspondingly, and a transmission shaft is rotationally connected with the middle section position of the top between the two supporting plates. The valve is simple in structure, reliable in performance, light in size and weight and suitable for a light-weight structure of a train air conditioner, the movable plate is opened in a side-opening rotating mode, the phenomenon that a large amount of dust and silt enter a linear guide rail sliding block to be stuck in the train running process is avoided, the risk of safe running of the train is greatly reduced, maintenance is avoided, the reliability is high and the use is facilitated.
本发明公开了一种列车侧开式电动压力波保护阀,包括安装底板,所述安装底板顶面两侧靠近边缘位置通过多个第一六角螺钉分别固接两个侧板,两个所述侧板相互靠近一侧分别固接两个第一轴套,两个所述第一轴套之间转动连接轴杆,所述轴杆通过多个第二六角螺钉固接动板一侧顶面,所述安装底板顶面两侧分别垂直固接两个支板,两个所述支板之间顶部中段位置转动连接传动轴。本发明结构较为简单,性能可靠,体积重量较轻,适用于列车空调的轻量化结构,使用侧开转动的方式打开动板,避免了在列车运行过程中大量灰尘泥沙进入直线导轨滑块中出现卡死的现象,大大减少了列车安全运行的风险,做到免维护,高可靠性,更利于使用。
