Description

液化气钢瓶气口快换接头
本实用新型涉及一种燃气钢瓶气口快换接头。
现有的减压阀与液化气钢瓶气口为螺纹连接,这种连接方式使钢瓶在更换时卸装减压阀操作不便。
本实用新型的目的在于提供一种液化气钢瓶气口快换接头,使减压阀与液化气钢瓶气口的对接在操作上简单快捷而且密封可靠。
本实用新型的目的是这样实现的:
一种液化气钢瓶气口快换接头,包括插头,其特征在于还包括夹头体和与夹头体固定为一体的接套,在夹头体内装有通断活塞、弹簧、密封圈,在夹头体上装有滚珠,在夹头体的外面与滚珠对应的位置上装有一外推活动套,在夹头体的里面装有一可活动的内推套,外推活动套、内推套与夹头体之间分别设有弹簧。
如上所述的接头,其特征在于插头头部为锥体形,中部的圆柱上有截面形状为齿形的凸圈和凸圈沟槽。
如上所述的接头,其特征在于密封圈截面形状为U型。
本实用新型的特点在于只须直接将插头插入夹头体内,即刻外推套自动将钢球卡牢插头,为液化气站对大量的空钢瓶实现快速充气提供了方便,也为家庭使用液化气提供了方便,本实用新型还可防止乱倒空钢瓶内的残液,防止充满液化气的备用钢瓶因角阀误开而造成液化气泄漏,具有很强的安全自动保护功能。
下面结合附图对本实用新型的结构作进一步的说明:
图1为本实用新型的结构示意图
本实用新型包括插头1,夹头体2和与夹头体2固定为一体的接套3,在夹头体2内装有通断活塞4、弹簧5、密封圈6。夹头体2、接套3、活塞4、弹簧5、密封圈6构成一通断开关,在插头1没有插入时,能自动密封气口防止钢瓶内气体外溢,在夹头体2上装有滚珠7,在夹头体2的外面与滚珠7对应的位置上装有一外推活动套8,在夹头体2的里面装有一可活动的内推套9,外推活动套8、内推套9与夹头体2之间分别设有弹簧10、11。
插头1尾端有螺孔,直接与现有的减压阀上的外螺纹接套连接;插头1头部为锥体形,能与密封圈6紧密配合而不漏气;插头1中部的圆柱上有截面形状为齿形的凸圈和凸圈沟槽。
本实用新型在使用时,将夹头体2的外纹与钢瓶连接。当装有减压阀的插头直接插入夹头体2内时,插头的台阶推动内推套9缩进去,使插头1的凸圈沟正好对准原来由内推套9托住的外突滚珠7,此时,滚珠7在外推套8的内斜面推挤压下,迅速落入插头1凸圈沟槽,卡住插头1而不能让其移动;插头1的锥体形则与密封圈6配合,而不漏气;插头1顶端则顶开活塞4,使钢瓶气口打开。若拨出插头(1),则须拨动外推套(8)向右移,此时插头(1)凸圈沟槽在弹簧力的作用下,挤动滚珠(7)外突入而进入外推套(8)让出的空隙,同时,插头(1)被弹出。
夹头内密封圈(6)截面形状为U型,便于卡套(12)卡住密封圈(6)使密封效果更好。
