Description

燃料箱用压力阀
技术领域
本发明涉及阀装置,更加具体的,涉及燃料箱用压力阀。
背景技术
通常,燃油泵通过DC马达获得蓄电电源而被驱动,从而将储存在燃料箱中的燃料供给到喷油器,所述燃油泵分为设置在发动机室的外置型燃油泵和设置在燃料箱内的内置型燃油泵,大多使用抑制燃油泵的噪音并防止气阻及燃料的脉动的内置型燃油泵。并且,在燃料箱内设有燃料箱用压力阀,当汽车倾覆时通过燃料箱用压力阀来防止燃料箱内的燃料或蒸发气体泄漏至外部。
即,由于汽车的燃料具有高挥发性,在如夏季户外气温高的情况下,容易蒸发成气态,当蒸发的气体充满燃料箱内时,燃料箱内部的压力增高,燃料或蒸发气体可能会泄漏,并且发生碰撞事故时会发生爆炸而使损失扩大。因此,通常汽车的燃料供给系统中,将燃料箱的蒸发气体引导至进气系统的进气管,与空气一同吸入到气缸并使其燃烧,为防止汽车行驶中发生的燃料流动或车体倾斜导致燃料进入导管内,将燃料箱用压力阀设置在燃料箱内。
然而,现有的上述燃料箱用压力阀,压力阀内部未设置有防止从喷嘴处气体逆流的结构。
发明内容
本发明的针对现有技术中存在的不足,提供了燃料箱用压力阀。
本发明是通过如下技术方案实现的:燃料箱用压力阀,包括:
主壳体,所述主壳体包括第一容腔和第二容腔,所述第一容腔和所述第二容腔之间通过通道连通,在所述第一容腔的底部设置有密封所述第一容腔该底部的底盖;
浮动阀芯,其活动设置在所述第一容腔内,在浮动阀芯和底盖之间设置的弹性偏压所述浮动阀芯的弹簧,通过所述浮动阀芯在所述第一容腔内活动,以使得所述浮动阀芯将所述通道封闭或者打开;
导流嘴,其固定设置在所述第二容腔的一侧且与所述第二容腔内部连通;
在所述第二容腔内设置有密封座,在所述密封座上设置有密封堵块。
上述技术方案中,所述主壳体具有上端开口,在所述开口上盖设有将其密封的盖板。
上述技术方案中,在所述主壳体上设置有限位扣槽,还包括一安装盖板,在所述安装盖板上设置有向下延伸的扣脚,所述扣脚扣入所述限位扣槽内。
上述技术方案中,所述扣脚设置在所述安装盖板的左右两侧以及后侧。
上述技术方案中,在所述浮动阀芯的侧壁上设置有纵向延伸的两条导向筋,在所述第一容腔对应位置设置有与所述导向筋形状和位置匹配的导向槽。
本发明具有如下有益效果:本发明的燃料箱用通过第二容腔内设置的密封座和密封堵块,使得可以防止从导流嘴处的回流气体进入至燃油箱内。
