Description

一种单向阀
技术领域
本实用新型涉及一种单向阀,属于阀门领域。 
背景技术
    单向阀的作用是只允许流体想单个方向运动,当流体向相反方向运动时,单向阀可以自行的关闭,以防止高压进入低压系统,目前,单向阀主要是由接头、橡胶垫、撑头、弹簧和下接头构成,橡胶垫依靠弹簧起支撑作用,结构简单,但长期使用和受到压力冲击时,弹簧会发生偏移,致使橡胶垫产生倾斜,阀门的密封效果受到很大影响。 
实用新型内容
    为了缓解现有技术的不足和缺陷,本实用新型的目的在于提供一种单向阀,本实用新型结构简单、占用空间小、系统集成度高、使用寿命长,易于安装和维护,简单方便、可靠性强。 
     为了实现上述目的本实用新型采用如下技术方案: 
     单向阀,包括阀体,其特征在于:所述的阀体的内腔设有水平阀杆,所述水平阀杆的左、右两端分别安装有阀门导套和橡胶阀门,所述的水平阀杆外壁上还套有弹簧,所述的弹簧夹装在阀门导套与橡胶阀门之间,所述阀体左侧连接有二通接头。
所述的单向阀,其特征在于:所述的二通接头与阀体之间设有螺母和O型密封圈。 
所述的单向阀,其特征在于:所述的螺母右侧还设有密封圈。 
本实用新型的优点: 
本实用新型结构简单、占用空间小、系统集成度高、使用寿命长,易于安装和维护,简单方便、可靠性强。
附图说明
图1    本实用新型的结构示意图。 
具体实施方式
    实施例:参考附图1,单向阀,包括阀体1,阀体1的内腔设有水平阀杆2,水平阀杆2的左、右两端分别安装有阀门导套3和橡胶阀门4,水平阀杆2外壁上还套有弹簧5,弹簧5夹装在阀门导套3与橡胶阀门4之间,阀体1左侧连接有二通接头6,二通接头6与阀体1之间设有螺母7和O型密封圈8。
