Abstract

本实用新型涉及对一种柴油箱盖的改进。在柴油箱盖上有可以上、下活动的密封球体,柴油箱内外有外部通气孔、密封通气孔、中间通气孔,由迷宫式的通道连通,密封球体下部有油压孔。该带翻倒阀柴油箱盖,在柴油箱正常使用时,可以内外通气保持压力平衡,当汽车发生事故翻车、倾斜或转弯时,翻倒阀关闭达到密封作用。

Description

带翻倒阀柴油箱盖
本实用新型涉及对一种汽车柴油箱盖的改进。
通常的汽车柴油箱盖为了让柴油箱内部压力与外部压力平衡,均采用常通式柴油箱盖,即在柴油箱盖上有与外界常通的孔,如果发生翻车、倾斜或转弯时,柴油会从柴油箱盖的常通孔溅出,翻车时柴油会有大量外泄引起火灾的危险。
本实用新型的目的在于提供一种带翻倒阀的汽车柴油箱盖,在汽车翻倒、倾斜或转弯时,柴油箱盖上的翻倒阀关闭,柴油不会从柴油箱盖通气孔溅出或外泄,正常使用时翻倒阀开启,可以正常通气。
结合附图1、图2本实用新型是这样实现的。当柴油箱正常使用时,锁爪5把柴油箱盖锁在柴油箱上,密封胶垫9使柴油箱盖与箱体密封,密封球体7受重力作用处于下部(可以上下移动),柴油箱内、外通过内部通气孔6、密封通气孔3,中间通气孔2、外部通气孔1由迷宫式道通而通气。当汽车翻车、倾斜或转弯时,柴油将从油压孔8将密封球体7压到(加上重力作用)密封通气孔3上,使其密封,以避免柴油外泄和溅出。锁扣4用于防柴油箱盖脱落锁用。
按照上述结构制成的带翻倒阀柴油箱盖,当柴油箱在正常使用时,柴油箱盖可通气,保证箱内、外压力平衡,当柴油箱倒置(翻车造成)、倾斜或转弯时(柴油受离心力作用向外涌),翻倒阀关闭,避免了柴油外泄与溅出,可降低出现事故后的危险因素。
附图说明:
图1、带翻倒阀柴油箱盖主视图
图2、图1的俯视图
实施例:按照附图所示结构可用在柴油卡车或其他车型的柴油箱上,一般安装尺寸应按QC/T《汽车燃油箱盖及尺寸》的要求执行,其中翻倒阀上的通气孔面积不小于12mm2密封球体一般为Φ16即可,带翻倒阀柴油箱盖体用塑料或尼龙注塑制成,翻倒阀的角度可根据柴油箱盖在柴油箱上的角度而定,密封球体由金属或密度大于柴油的非金属制成,锁爪由具有一定的刚度的金属的制成,密封胶垫由耐油橡胶制成。
当汽车发生事故翻车、倾斜或柴油箱加满油转变时,密封球体在重力或离心作用下,会堵住密封通孔而达到密封作用。正常使用时,柴油箱盖可通过通气孔通气。
