Description

防水过滤的汽车排气管
技术领域
本发明属于汽车排气管设备技术领域，具体涉及防水过滤的汽车排气管。
背景技术
同时，随着城市机动车辆增长的加快快，伴随而来的交通噪声污染环境现象也日益突出，汽车对环保最大的危害是噪音污染，空气污染，调查表明，机动车噪声占城市噪声的75.5％，随着汽车节能减排的发展，要求汽车降低噪音，节约能源消耗。而汽车最主要的噪声来自汽车的排气系统，即汽车尾气排放噪音，为了降低汽车尾气排放噪音，满足汽车环保的要求。排气管是汽车上很常见的排气部件，其进气口接入来自发动机排出的气体，并从排气管的出气口排出。现有的汽车尾气排气管通常包括左排气管和右排气管，它们二者独立，通常各自具有四个进气口，分别接收来自发动机所排出的气体。普通的排气管一般包括排气管主体、排气连接管和外壳等，也可直接将外壳安装在排气管主体上，而无需排气连接管。现有汽车排气管通常只有一个排气主管，而在使用中，由于通常的汽车排气管设置在汽车底部，在遇到下雨天气、或途径积水的路段，位置较低的排气管极易引起水倒灌进排气管，容易造成发动机损坏。目前还没有有效的装置解决汽车防倒灌的问题。
发明内容
针对现有技术中存在的问题，本发明的目的在于提供防水过滤的汽车排气管。
本发明采取的技术方案为：
防水过滤的汽车排气管，管体的进气口设为口径递减的锥形形状，出气口设为口径递增的锥形形状，进气口和出气口之间设置有连接部，在连接部上设有插接槽，在所述插接槽内设有密封圈，在管体内壁设有向下的防水挡片，在防水挡片与管体出气端之间设有当水进入管体时能向防水挡片移动的活动防水挡片机构；进气口和连接部之间设置有连通管，连通管内设有过滤装置，过滤装置内设置有椭球体的过滤层，过滤层和连通管之间设置有单向打开的过滤网。
进一步的，所述防水挡片的连接处设为向内凹陷，并且密封圈与该凹陷相契合。
进一步的，所述密封圈外侧设置有支撑环。
进一步的，所述管体外表面上设有消音装置。
进一步的，所述管体内壁上设有隔热层。
本发明的有益效果为：
本发明中的锥形进气口和出气口能够方便尾气排放，而且能更好的起到散热的效果，过滤装置的设置能够减少占用空间，过滤效果明显，通过连通部使进气口和出气口的气体可以相互流通，从而气压相等，且回压也均衡且互不污染，避免回压不同而影响到发动机的运行状。本发明中防水挡片朝向活动防水挡片机构和密封条的协同作用，防水挡片与密封圈接合在一起时，能将管体有效密封，防水性强。
具体实施方式
防水过滤的汽车排气管，管体的进气口设为口径递减的锥形形状，出气口设为口径递增的锥形形状，进气口和出气口之间设置有连接部，在连接部上设有插接槽，在所述插接槽内设有密封圈，在管体内壁设有向下的防水挡片，在防水挡片与管体出气端之间设有当水进入管体时能向防水挡片移动的活动防水挡片机构；进气口和连接部之间设置有连通管，连通管内设有过滤装置，过滤装置内设置有椭球体的过滤层，过滤层和连通管之间设置有单向打开的过滤网。
进一步的，所述防水挡片的连接处设为向内凹陷，并且密封圈与该凹陷相契合。
进一步的，所述密封圈外侧设置有支撑环。
进一步的，所述管体外表面上设有消音装置。
进一步的，所述管体内壁上设有隔热层。
以上所述并非是对本发明的限制，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明实质范围的前提下，还可以做出若干变化、改型、添加或替换，这些改进和润饰也应视为本发明的保护范围。
