The invention discloses an explosion-proof vehicle and a display instrument thereof. The explosion-proof vehicle comprises a cover plate and a shell, the cover plate and the shell form a closed cavity for installing an instrument module, and the explosion-proof vehicle also comprises a visual window assembly arranged in the closed cavity and fixedly connected with the cover plate; an instrument module arranged between the visual window assembly and the shell; and the cover plate is hermetically connected with the shell. When the display instrument is applied, firstly, the cover plate and the shell form a closed cavity to prevent explosive gas in the instrument box from being transmitted to the external environment due to the fact that sparks of an electric appliance ignite the explosive gas, and meanwhile it is ensured that external explosive dust cannot enter the instrument box; secondly, parameters of the instrument module are observed through the visual window assembly, and meanwhile, the visual window assembly is fixedly connected with the cover plate, so that the explosion-proof performance is ensured. The protection grade of the display instrument is IP65, and the display instrument is suitable for flammable and combustible occasions, high in safety coefficient, strong in operation function, stable in performance and suitable for explosive gas environments or combustible dust environments with the environments of IIA-grade and IIB-grade T1-T6 groups.
本发明公开了一种防爆车辆及其显示仪表,包括盖板和壳体,盖板和壳体形成用以安装仪表模块的密闭腔体,还包括:设于密闭腔体内、与盖板固连的可视窗组件;设于可视窗组件和壳体间的仪表模块;盖板和壳体之间密封连接。应用该显示仪表,第一,盖板和壳体形成密闭腔体,用以防止仪表盒内由于电器火花点燃内部的爆炸性气体传递至外部环境中,同时确保外界的爆炸性粉尘不能进入仪表盒中;第二,通过可视窗组件实现对仪表模块的参数的观测,同时可视窗组件与盖板固连,保证防爆性能;上述显示仪表的防护等级为IP65,适用于易燃易爆的场合,安全系数高、操作功能强且性能稳定,适用于环境为IIA、IIB级T1~T6组的爆炸性气体环境或可燃性粉尘环境。
