Abstract

本实用新型提出了防爆液化气瓶，其技术方案为：在液化气瓶体的上端焊接有一个圆柱形凸台，圆柱形凸台上加工有内孔，液化气瓶体上也相应设有孔，圆柱形凸台上的内孔通过液化气瓶体上的孔与液化气瓶内部相通，圆柱形凸台上设有外螺纹；一个带台阶孔的螺套旋在圆柱形凸台上，直接把一个防爆板压在圆柱形凸台的端面上。当液化气瓶内的气压升高到设定的压力，防爆板在气压的作用下发生变形，防爆板从螺套中弹出，液化气瓶内的气体泄压，液化气瓶就不会爆炸。

Description

防爆液化气瓶
技术领域
本实用新型涉及一种具有防爆功能的液化气瓶。 
背景技术
目前的液化气瓶，都只在瓶口有一个阀门，不用时是关闭的，当发生火灾或重击瓶体时，造成瓶内的气压升高，就可能有爆炸的危险。 
发明内容
为了避免液化气瓶在发生火灾或重击瓶体时发生爆炸，本实用新型提出防爆液化气瓶。 
为此，其技术方案为：防爆液化气瓶，其特征在于：在液化气瓶体的上端焊接有一个圆柱形凸台，圆柱形凸台上加工有内孔，液化气瓶体上也相应设有孔，圆柱形凸台上的内孔通过液化气瓶体上的孔与液化气瓶内部相通，圆柱形凸台上设有外螺纹；一个带台阶孔的螺套旋在圆柱形凸台上，直接把一个防爆板压在圆柱形凸台的端面上。 
有益效果：当液化气瓶内的气压升高到设定的压力，防爆板在气压的作用下发生变形，防爆板从螺套中弹出，液化气瓶内的气体泄压，液化气瓶就不会爆炸。 
附图说明
图1是本实用新型的结构示意图。 
具体实施方式
如图1所示的防爆液化气瓶，在液化气瓶体1的上端焊接有一个圆柱形凸台2，圆柱形凸台2上加工有内孔，液化气瓶体上也相应设有孔5，圆柱形凸台2上的内孔通过液化气瓶体上的孔5与液化气瓶内部相通，圆柱形凸台2上设有外螺纹，一个带台阶孔的螺套4旋在圆柱形凸台2上，直接把一个防爆板3压在圆柱形凸台的端面上。
