The invention discloses a combination valve in the field of an automobile oil tank. The valve comprises a valve body mounted in the oil tank, wherein a first exhaust hole and a second exhaust hole areformed in the top of the valve body, a first valve piece for opening and closing the first exhaust hole and a second valve piece for opening and closing the second exhaust hole are arranged in the valve body, the first valve piece is elastically arranged in the valve body through a first spring, the first exhaust hole is opened and closed through ascending and descending, a concave table is machined on a side portion of the first valve piece, the second valve piece is elastically arranged on the concave table through a second spring, the second exhaust hole is opened and closed through lifting, the first valve piece closes the first exhaust hole firstly along with rising of the liquid level in the oil tank, functions of the first valve piece and the second valve piece can be achieved through a single valve body, the size is smaller, and the installation space is saved.
本发明公开了汽车油箱领域内的一种组合阀,包括安装在油箱内的阀体,阀体的顶部开设有连通油箱内外的第一排气孔和第二排气孔,阀体内设置有用以实现第一排气孔开闭的第一阀件和实现第二排气孔开闭的第二阀件,第一阀件通过第一弹簧被弹性设置在阀体内,且通过升降来对第一排气孔进行开闭,第一阀件的侧部加工有凹台,第二阀件通过第二弹簧被弹性设置在凹台上,且通过升降来对第二排气孔进行开闭,随着油箱内液位的上升,第一阀件先将第一排气孔关闭,本发明可实现单个阀体实现第一阀件、第二阀件的功能,体积更小,节约了安装空间。
