Abstract

一种铸管接口,涉及用2GS铸管连接成管道的接口结构,在铸管承口的内凹槽中嵌装有用来密封的唇形胶圈,另一根铸管的插口插在所述铸管的承口内,将唇形胶圈紧紧挤压在铸管的承口和插口之间,所述唇形胶圈与管内液体接触面为唇形凹面。它具有结构简单、密封效果好的优点。

Description

铸管接口
(一)、技术领域
本实用新型涉及一种用2GS铸管连接成管道的接口结构。
(二)、背景技术
目前,滑入式柔性接口利用橡胶圈的自密封作用来保持管道密封,由于密封圈与管内液体接触面平面或凸面,密封效果差,尤其在管内压力高时,常发生泄漏事故。
(三)、发明内容:
为了克服现有技术的缺点,本实用新型提供一种2GS铸管接口,它结构简单,密封效果好,尤其适合高压液体的输送。
本实用新型解决其技术问题所采取的技术方案是:在铸管承口的内凹槽中嵌装有用来密封的唇形胶圈,另一根铸管的插口插在所述铸管的承口内,将唇形胶圈紧紧挤压在铸管的承口和插口之间,所述唇形胶圈与管内液体接触面为唇形凹面。
由于采用唇形胶圈,这样管道压力越大,胶圈和管壁的接触压力越大,更好的保证了密封。
(四)、附图说明
下面结合附图和实施例对本实用新型进一步说明。
附图为本实用新型局部剖视图。
(五)、具体实施方式
在铸管承口2的内凹槽5中嵌装有用来密封的唇形胶圈3,另一根铸管的插口1插在所述铸管的承口2内,将唇形胶圈3紧紧挤压在铸管的承口2和插口1之间,所述唇形胶圈3与管内液体接触面4为唇形凹面。所述唇形胶圈3与管内液体接触面4也可为三角形或半圆形。

Claims (2)

1、一种铸管接口,在铸管承口(2)的内凹槽(5)中嵌装有用来密封的唇形胶圈(3),另一根铸管的插口(1)插在所述铸管的承口(2)内,将唇形胶圈(3)紧紧挤压在铸管的承口(2)和插口(1)之间,其特征在于:所述唇形胶圈(3)与管内液体接触面(4)为唇形凹面。
2、根据权利要求1所述的铸管接口,其特征在于:所述唇形胶圈(3)与管内液体接触面(4)也可为三角形或半圆形。
