Abstract

本实用新型提供了一种双层金属波纹管,由内层不锈钢和外层不锈钢二层制成,对内层不锈钢的内壁和外层不锈钢的外壁进行喷塑处理。本实用新型的有益效果是耐煤气介质腐蚀,密封效果好,大大延长了设备的使用寿命。

Description

一种双层金属波纹管
所属技术领域
本实用新型涉及一种波纹管,尤其是一种双层金属波纹管。
背景技术
目前使用在工业煤气系统使用的眼镜阀,大多采用金属波纹管作为伸缩部件,在煤气介质的腐蚀下,波纹管易被腐蚀穿孔,导致煤气泄漏,造成事故。
发明内容
为了克服现有眼镜阀的波纹管不耐煤气腐蚀,易穿孔,导致煤气泄漏的不足,本实用新型提供一种双层金属波纹管。
本实用新型解决其技术问题所采用的技术方案是:一种双层金属波纹管,由内层不锈钢和外层不锈钢二层制成,对内层不锈钢的内壁和外层不锈钢的外壁进行喷塑处理。
本实用新型的有益效果是耐煤气介质腐蚀,密封效果好,延长了设备的使用寿命。
附图说明
图1是实施例的剖面构造图
图中:1.波峰;2.外层不锈钢;3.内层不锈钢。
具体实施方式
如图1所示,一种双层金属波纹管,由内层不锈钢2和外层不锈钢3二层制成多个波峰1,对内层不锈钢3的内壁和外层不锈钢2的外壁进行喷塑处理。大大增加了耐磨防腐性能。
