Abstract

本实用新型公开了一种密封垫,为圆环形,所述密封垫由上层的软质硅胶和下层的橡胶组成。本实用新型通过在橡胶上增加一层软质硅胶层,在使用时,软质硅胶层能将内外空气隔绝,密封效果更好。且由于橡胶皮与橡胶连接成一个整体,因此更不易损坏。

Description

密封垫
技术领域
本实用新型涉及一种密封垫,具体涉及一种含有软质硅胶的密封垫。 
背景技术
密封垫应用较广,广泛应用在多种领域。目前常见的密封垫只是由单层橡胶组成,虽然也能起到密封作用。但有时候会出现密封不严实的情况。 
实用新型内容
本实用新型的目的就在于提供一种密封效果好的复合密封垫。 
本实用新型是这样实现的: 
一种密封垫,为圆环形,所述密封垫由上层的软质硅胶和下层的橡胶组成。 
更进一步的方案是:所述的软质硅胶外部有橡胶皮包裹,橡胶皮与橡胶连接成一个整体。 
本实用新型通过在橡胶上增加一层软质硅胶层,在使用时,软质硅胶层能将内外空气隔绝,密封效果更好。且由于橡胶皮与橡胶连接成一个整体,因此更不易损坏。 
附图说明
图1为本实用新型的结构示意图。 
图2为图1的A向视图。 
具体实施方式
下面结合附图对本实用新型做进一步的说明。 
如附图1、2所示,一种密封垫,为圆环形,所述密封垫由上层的软质硅胶2和下层的橡胶1组成。所述的软质硅胶外部有橡胶皮3包裹,橡胶皮与橡胶连接成一个整体。 

Claims (2)
