Abstract

本实用新型涉及一种管道接头,该管道接头的本体的相对于外螺纹的另一侧的内孔内依次设有锁圈和密封圈,在本体的靠外螺纹一侧的内孔内安装有中空的弹簧支架,弹簧安装在弹簧支架上且面向锁圈和密封圈一侧,阀板固定在弹簧支架上且可在弹簧支架上活动,弹簧套设在阀板上。采用本实用新型,将其安装在管道上,在停水时,能防止水倒流,尤其适用于具有太阳能热水器的用户。

Description

一种管道接头
技术领域
本实用新型涉及一种管道接头。 
背景技术
目前,用户在使用太阳能热水器时,必须在水表出水口后再安装一个止回阀门,否则,在停水时,太阳能热水器的热水会产生倒流,烫坏水表机芯,迫使用户更换水表。 
发明内容
本实用新型的目的是提供在停水时,能防止水倒流的一种管道接头。 
本实用新型采取的技术方案是:一种管道接头,其特征在于在本体的相对于外螺纹的另一侧的内孔内依次设有锁圈和密封圈,在本体的靠外螺纹一侧的内孔内安装有中空的弹簧支架,弹簧安装在弹簧支架上且面向锁圈和密封圈一侧,阀板固定在弹簧支架上且可在弹簧支架上活动,弹簧套设在阀板上。 
采用本实用新型,将其安装在管道上,在停水时,能防止水倒流,尤其适用于具有太阳能热水器的用户。 
附图说明
图1是本实用新型的剖示立体示意图。 
图中序号表示:本体1、弹簧2、阀板3、密封圈4、锁圈5、外螺纹6和弹簧支架7。 
具体实施方式
下面结合具体的实施例对本实用新型作进一步说明。 
参照图1,该管道接头的本体1的相对于外螺纹6的另一侧的内孔内依次设有锁圈5(主要是装配时锁定位置用,也可视其与本体1呈一体)和密封圈4,在本体1的靠外螺纹6一侧的内孔内安装有中空(即具有空隙)的弹簧支架7,弹簧2安装在弹簧支架7上且面向锁圈5和密封圈4一侧,阀板3固定在弹簧支架7上且可在弹簧支架7上活动,弹簧2套设在阀板3上。 
使用时,将该管道接头安装在管道,当水流通过时,利用水流的压力压缩弹簧2并打开阀板3,当水流的没有压力即停水时,弹簧2伸张使阀板3密闭密封圈4的内孔,使水流不会产生倒流现象。该管道接头尤其适用于具有太阳能热水器的用户。
