Description

一种汽车排气管
技术领域
本发明涉及一种汽车排气管。
背景技术
排气管消音的原理是通过对排气气流气流折射、分散、膨胀等措施，使排气气流的流速降低。从而达到消音的目的。但是消音以后排气背压增高，影响废气排出的完全程度，会损失动力性和经济性。因此排气管的设计既要考虑到消音降噪，又要考虑动力性和经济性不要有太大的损失。除非十分必要，建议不要把排气噪音降得很低。
另外，这类排气管内的排气主管、出气主管和连通管的耐腐蚀性很差，使用寿命很短，经常需要更换。
发明内容
本发明要解决的技术问题是提供一种汽车排气管。
为解决上述问题，本发明采用如下技术方案：
一种汽车排气管，包括排气管主体、进气管口、过滤腔、回音腔、出气消音腔、出气管口、排气主管、出气主管和连通管，所述排气管主体包括过滤腔、回音腔和出气消音腔，所述进气管口与过滤腔相连，所述过滤腔、回音腔和出气消音腔之间通过隔板分隔设置，所述过滤腔内通过排气主管与出气消音腔相连，所述出气消音腔通过连通管与回音腔相连，所述回音腔通过出气主管与出气管口相连，所述过滤腔内部设置有过滤层，所述过滤层设置在排气主管的管口，所述出气消音腔内在出气主管上设置有消音器；
排气主管、出气主管和连通管均通过防腐蚀处理在其表面形成防护膜，加工工艺为：
步骤①、在工件上涂刷防腐基础液，防腐基础液由20份聚醋酸乙烯乳液、20份二乙醇胺、10份丙三醇、5份稀盐酸、0.5份花色甙、10份碳酸钾和80份水混合制成；
步骤②、在工件表面采用离子注入方式注入磷酸锆、二氧化硅、铬酸铬和氟硅酸钠形成厚度为100nm的不溶共络层；
步骤③、再在不溶共络层上形成金属氧化层；
步骤④、再在金属氧化层上涂厚度为100nm的底漆。
本发明结构简单，设计合理，通过过滤腔、回音腔、出气消音腔三个腔体相互配合设计分别实现了过滤、回音和消音工作，另外分别通过排气主管、出气主管和连通管进行相互连通，通过设置过滤层和消音器实现相关功能，具有高速高效、清洁安全、低成本、易维护，并且产品一致性得到保证，从而提高产品质量。通过防腐蚀处理排气主管、出气主管和连通管，使其耐腐蚀性能得到显著提升。
