【技术实现步骤摘要】
分体式轨道车辆的自调式废气排放装置
本技术涉及一种分体式轨道车辆的自调式废气排放装置,用于轨道车辆的废气排放。属于轨道车辆空气调节设备
技术介绍
轨道车辆都配置有空调设备,向客室内输送经处理的空气及室外新风,新风的持续引入会导致客室内内压增高。为保证车内空气质量及保持恒定气压,提高空调效率及乘坐舒适度,需排出车内等量新风的废气。早期的用于轨道车辆的废气排放装置有两种形式,一、自然排风,即通过窗户或车体开口安装风筒,直接向外排放废气,这种形式的缺点是室内外空气呈连通状态,室内空气压力随车外空气压力变化而变化,在隧道、会车时室内瞬时压力变化太大常会引起乘坐人员不适。二、强迫排风,即利用风机把室内废气强制排至室外。这种形式的缺点为风机连续工作会导致室内压力过低、增加电气安全风险及增加能耗。
技术实现思路
本技术的目的在于克服上述不足,提供了分体式轨道车辆的自调式废气排放装置。本技术的目的是这样实现的:分体式轨道车辆的自调式废气排放装置,其特点是:它包括外罩、内罩、密封毡,密封毡上开有进风口,内罩位于外罩内,内罩与外罩之间形成排风腔,内罩上设置有“Ω”形的卡箍,卡箍位于内罩与外罩之间,卡箍的上边与外罩连接,卡箍的下边与内罩、密封毡连接,内罩位于卡箍与密封毡形成的框体内,内罩包括斜面和直面,斜面上开有排气口,斜面上还设置有自调风门,自调风门的上端与斜面上部铰接,自调风门的大小与斜面上的排气口对应,挡雨板呈“√”形,挡雨板的一端直边与直面连接,挡雨板的另一端斜边位于内罩与外罩形成的排风腔内。本技术一种分体式轨道车辆的自调式废气排放装置,与斜面上部铰接的自调风门可 ...
