Description

一种板式曝气头胶圈
技术领域
本实用新型涉及一种板式曝气头胶圈。
技术背景
U型胶圈是法兰连接中最常用的密封元件,但一直存在着只要法兰变形,便密封不严的现象,通常采用增加法兰的硬度和厚度来解决此类问题,但这样会增加法兰的造价,也使得产品笨重。
实用新型内容
本实用新型所要解决的技术问题是提供一种密封性能好且经济耐用的板式曝气头胶圈。
本实用新型采用如下技术方案:
本实用新型所述胶圈内侧设置环形凹槽,在胶圈的上端设置上凸台,胶圈的下端设置下凸台。
本实用新型上凸台和下凸台的纵截面为半圆形。
本实用新型所述的上凸台或下凸台的周长与胶圈的周长相等。
本实用新型所述胶圈的材质为橡胶。
本实用新型积极效果如下:本实用新型的胶圈上设置上凸台和下凸台,即使压在胶圈上的法兰和过滤板有较大的变形也不会产生密封不严的现象,板式曝气头胶圈可广泛的应用于法兰密封中,根据不同的要求采用不同材质的胶圈即可。
附图说明
附图1为本实用新型结构示意图;
附图2为本实用新型剖面结构示意图;
附图3为本实用新型上凸台和下凸台纵向剖面结构示意图。
在附图中:1胶圈、2凹槽、3上凸台、4下凸台。
具体实施方式
如附图所示,本实用新型所述胶圈1内侧设置环形凹槽2,在胶圈1的上端设置上凸台3,胶圈1的下端设置下凸台4,上凸台3和下凸台4的纵截面为半圆形,且上凸台3或下凸台4的周长与胶圈1的周长相等,所述胶圈1的材质为橡胶。
本实用新型的胶圈上设置上凸台3和下凸台4,即使压在胶圈上的法兰和过滤板有较大的变形也不会产生密封不严的现象,板式曝气头胶圈可广泛的应用于法兰密封中,根据不同的要求采用不同材质的胶圈即可。
