Abstract

本发明公开了一种结构对称的排气管垫，包括有垫片本体，垫片本体上设有两个排气孔和两个排气孔组，两个排气孔设置在两个排气孔组的两侧，各排气孔、排气孔组两两之间的垫片本体上设有安装孔，垫片本体的两端分别向外延伸设有弧形凸缘，弧形凸缘中也分别设有安装孔；所述的排气孔组包括有两个并排设置的排气孔，各排气孔的内壁上分别设有硅橡胶层和尼龙层构成的复合密封层。本发明结构对称、制作方便，定位防漏气效果好，适宜批量生产。

Description

一种结构对称的排气管垫
技术领域
    本发明主要涉及垫片领域，尤其涉及一种结构对称的排气管垫。
背景技术
垫片（gasket）是两个物体之间的机械密封，通常以防止的两个物体之间受到压力、腐蚀、和管路自然地热胀冷缩泄漏。由于机械加工表面不可能完美，使用垫片即可填补不规则性。现有技术中一般是一个垫片本体上开有多种孔，制造工艺复杂。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种结构对称的排气管垫。
本发明是通过以下技术方案实现的：
一种结构对称的排气管垫，包括有垫片本体，其特征在于：垫片本体上设有两个排气孔和两个排气孔组，两个排气孔设置在两个排气孔组的两侧，各排气孔、排气孔组两两之间的垫片本体上设有安装孔，垫片本体的两端分别向外延伸设有弧形凸缘，弧形凸缘中也分别设有安装孔；所述的排气孔组包括有两个并排设置的排气孔，各排气孔的内壁上分别设有硅橡胶层和尼龙层构成的复合密封层。
本发明的优点是：
本发明结构对称、制作方便，定位防漏气效果好，适宜批量生产。
附图说明
    图1为本发明的结构示意图。
具体实施方式
如图1所示，一种结构对称的排气管垫，包括有垫片本体1，垫片本体1上设有两个排气孔2和两个排气孔组3，两个排气孔2设置在两个排气孔组3的两侧，各排气孔2、排气孔组3两两之间的垫片本体1上设有安装孔4，垫片本体1的两端分别向外延伸设有弧形凸缘5，弧形凸缘5中也分别设有安装孔4；所述的排气孔组3包括有两个并排设置的排气孔2，各排气孔2的内壁上分别设有硅橡胶层和尼龙层构成的复合密封层6。
