Description

一种汽车排气管的防积水管
技术领域
本发明涉及汽车零部件技术领域，具体涉及一种汽车排气管的防积水管。
背景技术
汽车已是人们最常见的代步工具，而汽车排气管为整车的重要组成部分；汽车排气管是为排除发动机燃烧后的废气，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；因此，需要一种汽车排气管的防积水管。
发明内容
本发明的目的是为了克服现有技术的不足，而提供一种清洁效果好、减震吸噪、防水效果好的一种汽车排气管的防积水管。
本发明的目的是这样实现的：一种汽车排气管的防积水管，它包括连接件A，所述的连接件A内设置有固定圈，所述的连接件A的右方连接有前排气管，所述的前排气管的内部设置有消音器，所述的前排气管的尾部设置有连接件B，所述的前排气管的右方设置有后排气管，所述的后排气管的左侧设置有连接件C，所述的连接件B和连接件C通过螺栓组固定连接，所述的后排气管的中部设置有三元催化器和颗粒捕集器，所述的颗粒捕集器的右方设置有防积水管，所述的防积水管内壁的上方设置有上挡板，所述的防积水管内壁的下方设置有滑槽，所述的滑槽内设置有滑块，所述的滑块的上方固定连接有下挡板，所述的滑槽的右方设置有隔离板，所述的隔离板和防积水管通过复位弹簧连接，所述的防积水管的下方设置有排水管，所述的排水管的左侧设置有排水口，所述的防积水管的右方设置有出气口。
所述的固定圈由全氟醚橡胶制成。
所述的连接件B和连接件C之间设置有密封圈。
所述的前排气管、后排气管和防积水管的内壁上从内到外依次设置有隔热层和消音涂层。
所述的上挡板设置在滑槽的上方。
所述的三元催化器、颗粒捕集器和消音器可根据具体情况选择合适的型号。
本发明的有益效果是：本发明在发动机和连接件之间设置有固定圈，固定圈由全氟醚橡胶制成，具有良好的化学性质和耐高温性质，增强其密封性的同时又能不与之发生化学反应，产生新的废气污染；前排气管、后排气管和防积水管的内壁上从内到外依次设置有隔热层和消音涂层，隔热层能有效的防止热量的散失，将发动机产生的热能运用于三元催化器，提高其催化效率；在高温的作用下，颗粒捕集器内沉积的颗粒物就会氧化燃烧，从而可以有效地减少微粒物的排放；消音涂层有良好的消声、减震效果，还具有隔热、吸声、防锈、防腐蚀、延长金属的使用寿命；当水倒灌时，水就会推动下挡板向左移动，使上挡板和下挡板相互接触，从而避免水倒灌；同时，在水的压力下，隔离板便向下打开，从而使水从排水管内流出；双重保护措施，加强了对发动机的保护；当无水时，隔离板在复位弹簧的作用下恢复原位；下挡板在尾气的推动下，恢复原位；总而言之，本发明具有清洁效果好、减震吸噪、防水效果好的优点。
