Description

一种燃油蒸汽阀
技术领域
本实用新型涉及汽车燃油控制领域,具体讲是一种燃油蒸汽阀。
背景技术
燃油蒸汽阀是汽车燃油蒸汽控制***的关键零部件,安装在油箱上,一头通油箱,一头通碳罐,控制燃油蒸汽气压和当车身倾斜到一定角度时关闭燃油的油路,以防燃油泄漏。现有的阀通常采用钢珠,依靠阀门内部的压力进行严禁,然而这种密封形式由于接触面比较小,容易出现失效的情况。
实用新型内容
为解决上述技术问题,本实用新型提供一种燃油蒸汽阀,包括阀盖、弹簧、阀芯组件以及阀壳,所述阀芯组件设置在所述阀壳内,所述阀壳底部连接有锥形开口,所述锥形开口与管道连接,所述阀芯组件具有与所述锥形开口配合的形状。
优选地,阀壳以及阀芯组件都由聚甲醛制成。
在原始状态下,阀芯组件的锥形开口被堵住,当蒸汽压力增大时,阀芯组件被推开,锥形开口被打开,从而蒸汽能够进入管道。
本实用新型由于采用了锥形密封的形式,密封接触面接大,从而有效降低了密封失效的概率,从而大大提高了阀的可靠性。
附图说明
图1是本实用新型蒸汽阀的结构示意图。
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步详细地说明。
参见图1,蒸汽阀包括阀盖1、弹簧2、阀芯组件3以及阀壳4,阀芯组件3设置在阀壳4内部,阀壳4底部设置有锥形开口,通过追星开口与管道连接,阀芯组件3具有与锥形开口配合的形状,阀盖1通过四个点扣合在阀壳4上,弹簧2设置在阀芯组件与阀盖1之间。
安装时在阀壳4中,先放入阀芯组件3,再放入弹簧2以及阀盖1,对下正后,用手把阀盖1扣在阀壳4上,不得脱落。阀盖1压合应平整,阀盖1上四点均应完全扣住阀壳4,试着反转总成件,里面零件应转动灵活。
其中,阀芯组件3以及阀壳4都由聚甲醛制成。
