Description

一种具有外硬质限位圈的软密封装置
【技术领域】
本发明涉及一种软密封装置,具体涉及一种具有外硬质限位圈的软密封装置。
【背景技术】
已知的,在常规的液体管道接口中使用的是环状密封圈“也叫O形圈”,这种可以满足水或其它液体介质的密闭要求,但在化工行业中对于管道接口“连接法兰处”的要求更高,尤其是对于易爆的汽油或其它油品,不仅对于耐候性要求也非常高,而且需要密封圈具有严格地密闭要求;现有的O形橡胶圈在使用中,受到螺栓与螺母的制造质量、法兰刚度以及法兰对接面的光滑情况影响,受力拉长后失去应有的密闭效果。
【发明内容】
为了克服现有技术中的不足,本发明公开了一种具有外硬质限位圈的软密封装置,通过在橡胶圈的圆形槽内嵌入圆形环,使用中通过内嵌入圆形环、外环板使橡胶圈实现密封的同时防止橡胶圈老化位移,本发明可确保密闭效果符合要求。
为了实现所述发明目的,本发明采用如下技术:
一种具有外硬质限位圈的软密封装置,包括橡胶圈、硬质限位圈,在橡胶圈的外缘面中部设有圆形槽,硬质限位圈内侧的内嵌入圆形环嵌入所述橡胶圈的圆形槽内,在硬质限位圈外部设有外环板,所述外环板与内嵌入圆形环之间设有连接环。
所述的具有外硬质限位圈的软密封装置,在所述橡胶圈的外缘面与圆形槽之间设有槽口,所述槽口为“=”形结构,在“=”形结构槽口外侧的外缘面上下分别设有台阶,连接环处于所述“=”形结构的槽口内,所述外环板的上下两端对应槽口外侧的所述上下台阶。
所述的具有外硬质限位圈的软密封装置,所述橡胶圈的内面为竖立的环形平面。
所述的具有外硬质限位圈的软密封装置,在橡胶圈的上部面上设有至少两条上凸起条。
所述的具有外硬质限位圈的软密封装置,在橡胶圈的下部面上设有至少两条下凸起条。
由于采用了上述技术方案,本发明具有如下有益效果:
本发明所述的具有外硬质限位圈的软密封装置,通过在橡胶圈的外侧设置圆形槽,将内嵌入圆形环嵌入圆形槽中,使用中通过内嵌入圆形环、外环板使橡胶圈实现密封的同时防止橡胶圈老化位移,外环板、内嵌入圆形环起到对橡胶圈定型和增力的双重功效,可确保橡胶环使用过程不会拉长变形,所述橡胶圈的上下面上设置的上凸起条、下凸起条,可确保密闭效果符合要求;本发明结构简单,密闭效果优于现有技术。
【附图说明】
图1是本发明的立体结构示意图;
图2是本发明的橡胶圈结构示意图;
图3是本发明的橡胶圈与硬质限位圈的装配结构示意图;
图中:1、外环板;2、内嵌入圆形环;3、连接环;4、内面;5、橡胶圈;6、外缘面;7、上部面;8、上凸起条;9、下凸起条;10、圆形槽;11、台阶;12、槽口。
【具体实施方式】
参考下面的实施例,可以更详细地解释本发明;但是应当指出的是本发明并不局限于下述实施例;公开本发明的目的旨在保护本发明范围内的一切变化和改进。
结合附图1、2或3所述的具有外硬质限位圈的软密封装置,包括橡胶圈5、硬质限位圈,橡胶圈5的内面4为竖立的环形平面,在所述橡胶圈5的外缘面6中部设有圆形槽10,在所述橡胶圈5的外缘面6与圆形槽10之间设有槽口12,所述槽口12为“=”形结构,在“=”形结构槽口12外侧的外缘面6上下分别设有台阶11,硬质限位圈内侧的内嵌入圆形环2嵌入所述橡胶圈5的圆形槽10内,在硬质限位圈外部设有外环板1,所述外环板1与内嵌入圆形环2之间设有连接环3,连接环3处于所述“=”形结构的槽口12内,所述外环板1的上下两端对应槽口12外侧的所述上下台阶11,在橡胶圈5的上部面7上设有至少两条上凸起条8,在橡胶圈5的下部面上设有至少两条下凸起条9。
实施本发明所述的具有外硬质限位圈的软密封装置,设计时,通过在橡胶圈5的外侧设置槽口12、圆形槽10,其中槽口12高度略小于圆形槽10的内空腔高度,所述内嵌入圆形环2嵌入圆形槽10中,而连接环3架空在所述槽口12;将本发明放在两根对接管道的连接法兰之间,通过螺栓使两连接法兰将本发明压紧,这时内嵌入圆形环2、外环板1使橡胶圈5实现密封两连接法兰对接面的同时防止橡胶圈5老化位移,外环板1、内嵌入圆形环2起到对橡胶圈5定型和增力的双重功效,可确保橡胶环使用过程不会拉长变形,本发明的位置、形状得到长期保持,橡胶圈也不可能出现位移,确保了两连接法兰之间的密闭度。
本发明未详述部分为现有技术。
