Abstract

本实用新型涉及一种简易型变径通气管,它包括两段等径的通气管主体(1)以及设置于通气管主体(1)之间的变径段(2)组成,其特征在于所述变径段(2)的直径大于通气管主体(1)的直径,所述两段通气管主体(1)和变径段(2)是一体式结构。本实用新型将通气管上的三段管路做成一体式,这样不但节省成本,装拆也较方便,而且不存在连接处的密封性要求。

Description

简易型变径通气管
技术领域
本实用新型涉及一种通气管,尤其涉及一种简易的变径通气管。
背景技术
通过加油管从加油口往油箱里加油时,油箱里的气体会通过通气管排出,而当油箱里的油加满时,气体压力会增大,将一些油连着气体一起排出,但经过排气管(直径大于通气管)时,气体压力便会减小,油会回流到油箱内,气体则通过通气管排出。以往的通气管是由三段管子连接起来的,两头是直径相同的通气管,中间是变径(变大)的排气管,这种通气管的加工成本较高,装配也很麻烦,对于连接处的密封性要求高。
发明内容
本实用新型的目的在于克服上述不足,提供一种加工成本较低,装配简单的变径通气管。
本实用新型的目的是这样实现的:一种简易型变径通气管,它包括两段等径的通气管主体以及设置于通气管主体之间的变径段,所述变径段的直径大于通气管主体的直径,所述两段通气管主体和变径段是一体式结构。
与现有技术相比,本实用新型的有益效果是:
本实用新型将出气管上的三段管路做成一体式,这样不但节省成本,装拆也较方便,而且不存在连接处的密封性要求。
附图说明
图1为本实用新型的结构示意图。
其中: 
通气管主体1
变径段2。
具体实施方式
如图1所示,本实用新型涉及一种简易型变径通气管,它主要由两段等径的通气管主体1以及设置于通气管主体1之间的变径段2组成,所述变径段2的直径大于通气管主体1的直径,所述两段通气管主体1和变径段2是一体式结构。
