摘要：
本发明公开了用于摩托车燃油蒸汽采集系统中的单球式防倾阀，包括一个顶板和一个底板结构，所述顶板是一平面板，所述底板结构由两个斜面板构成，形成中间低，两端高的“V”形结构，在所述底板结构上放置有一滚球，滚球的左右两侧分别设置有一密封圈，所述密封圈分别垂直固定在所述底部的对应斜面板上，并与所述顶板相固接，滚球的直径大于密封圈的内径但小于密封圈的外径，在所述防倾阀的后端靠近所述顶板处开设有一透气孔，防倾阀通过透气孔与蒸汽采集管相通。本发明结构简单，成本低，工作可靠。
摘要（英）：

The invention discloses a single-ball anti-slope valve for a motorcycle fuel stream collection system. The valve comprises a top plate and a bottom plate structure, wherein the top plate is a plane plate; the bottom plate structure is composed of two slope panels and has a V-shaped structure which is low in the middle and high at two sides; a ball is arranged on the bottom plate structure; two sealing rings are arranged on the left and right sides of the ball, vertically fixed on the slope panels of the bottom plate structure respectively, and fixedly connected with the top plate; the diameter of the ball is greater than the inner diameter of the sealing rings but less than the outer diameter of the sealing rings; a vent hole is arranged at the rear end of the anti-slope valve close to the top plate; and the anti-slope valve is communicated with a stream collection pipe through the vent hole. The valve has the advantages of simple structure, low cost and reliable operation.
