The invention discloses a balance flow reducing valve for a fuel system, which comprises a mounting frame fixed on a partition wall of two adjacent main fuel tanks, and the center of the mounting frame is provided with a mounting cavity; the top end of the valve is rotationally connected into the mounting cavity through a swing shaft, and the bottom end of the valve is concavely provided with a flow reduction groove upwards; when the aircraft is in a level flight state, the flow reducing groove and the mounting frame can be clamped to form a flow passing hole so as to adjust the fuel quantity in the two adjacent main fuel tanks; when the aircraft is in an inclined flight state, the valve can rotate in the axis direction of the swing shaft so as to adjust the size of the overflowing hole or close the overflowing hole. The fuel balance problem of a large-volume fuel tank of a small fuel system is solved, long voyage and high maneuverability of a small aircraft are both considered, and the flight performance of the small aircraft is greatly improved.

    本发明公开了一种用于燃油系统的平衡减流活门,包括:安装框架,固定在相邻的两个主油箱的分隔壁上,所述安装框架的中心形成有安装腔;活门,顶端通过摆动轴转动连接在所述安装腔内,所述活门的底端向上凹设有减流槽;在飞行器处于平飞状态时,所述减流槽能与所述安装框架夹设形成过流孔以调整相邻两个所述主油箱之中的燃油量;在飞行器处于倾斜飞行状态时,所述活门能沿着所述摆动轴的轴线方向进行转动以调整所述过流孔的大小或关闭所述过流孔。本发明解决了小型燃油系统大容积油箱的燃油平衡问题,实现小型飞行器对于长航程和高机动能力的兼顾,大大提升了其飞行性能。
