Abstract

真空管道交通的密封垫，用橡胶制成门框大小的椭圆形，其横截面呈“工”字形，在“工”字形的上边线设置凸缘和软边，在“工”字形的底边线中心开孔，该孔通至凸缘内，用“工”字形的凹口嵌入门框的凹槽中加以固定，密封垫的中心孔通大气，这样的密封垫是利用气压差来克服旅客通道密封门易泄气的目的。

Description

真空管道交通的密封垫
技术领域
本发明涉及一种真空管道交通的密封门，具体地说是密封门与管道内车厢接触的密封垫圈。
背景技术
利用真空管道交通工具来运送旅客，具有速度快，能耗低，不受气候影响以及占地少等优点，今后将会取代那种能耗大、费用高、受气候影响大的交通工具，但是，真空管道的密封要求很高，尤其是站台管道上下旅客密封门与车厢的接触面易泄气，直接影响管道内的真空度，如何提高密封性能是真空管道交通必须解决的问题。
发明内容
为了克服真空管道上密封门与车厢接触面易泄气的缺陷，本发明提供一种真空管道交通的密封垫，该密封垫设置凸缘和软边，可以达到不泄气的要求。
本发明解决其技术问题所采取的技术措施是，密封垫用橡胶制成门框大小的椭圆形，其横截面呈“工”字形，在“工”字形的上边线设置凸缘和软边，在“工”字形的底边线中心开孔，该孔通至凸缘内，用“工”字形的凹口嵌入门框的凹槽中加以固定，密封垫的中心孔通大气，使用时，将密封门的门框上的密封垫紧贴在管道内的车厢门框的四周，由于管道内处在真空状态，大气的压力通过中心孔通到凸缘内，使凸缘紧压在车厢门四周的平面上，实行密封，如果凸缘稍有泄气，泄气处就会有气流通过，这时密封垫的软边则会在大气压力下紧贴在泄气处进行二次密封，这样的密封垫是利用气压差来实现进一步密封的，从而达到克服真空管道交通密封门与车厢门的接触面易泄气的目的。
本发明的有益效果是，为真空管道交通的发展提供一种密封门的密封垫，结构简单。
附图说明
下面结合附图对本发明作进一步说明。
图1是真空管道交通的密封垫的结构示意图；
图2是真空管道交通的密封垫的横截面示意图。
图中，1、密封垫本体，2、底边，3、上边，4、凸缘，5、凸缘，6、软边，7、扣槽，8、气孔。
具体实施方式
在图1中，密封垫本体1用橡胶制成椭圆形。
在图2中横截面呈“工”字形状，“工”字形的上边3设凸缘4和凸缘5，在椭圆形内圆的边缘逐渐变薄形成软边6，“工”字形的凹槽成扣槽7，扣嘈固定在门框的凹槽中，在“工”字形的底边2的中心开气孔8，气孔通至凸缘4和5的中心内，气孔8通大气。
