Description

一种管道伸缩节
技术领域
本实用新型涉及一种伸缩装置,尤其是一种管道伸缩节。
背景技术
目前使用在工业管道的伸缩节,一般采用带波纹管的伸缩节,波管一般为单波,使用时间一长易产生破损,另外,内套筒与右筒体之间通过橡胶O形圈密封,其存在耐温低,磨损快,易引起泄漏,造成安全隐患。
发明内容
为了克服现有伸缩体单波波纹管易损坏,橡胶O形圈耐温低,磨损快,易引起泄漏,造成安全隐患的不足,本实用新型提供一种管道伸缩节。
本实用新型解决其技术问题所采用的技术方案是一种管道伸缩节,包括左筒体、右筒体、内套筒,内套筒焊接在右筒体内,左筒体上有一台阶,左筒体与右筒体之间还焊有波纹管,左筒体上与内套筒配合处还装有O形圈,波纹管为双波波纹管。O形圈为金属O形圈。
本实用新型的有益效果是产品结构简单,耐高温、耐磨损性能好,使用寿命长。
附图说明
下面结合附图和实施例对本实用新型作进一步说明。
图1是实施例的构造图;
图中:1.左筒体;2.台阶;3.O形圈;4.波纹管;5.内套筒;6.右筒体。
具体实施方式
如图1所示,一种管道伸缩节,包括左筒体1、右筒体6、内套筒5,内套筒5焊接在右筒体6内,左筒体1上有一台阶2,起轴向限位作用,左筒体1与右筒体6之间还焊有波纹管4,左筒体1上与内套筒5配合处还装有O形圈3,波纹管4为双波波纹管,O形圈3为金属O形圈。
