The invention relates to the technical field of aviation aircraft fuel tanks, in particular to a wing built-in aviation fuel tank pressurizing device. The device includes an aviation fuel tank, a pressurizing insertion pipe is inserted into an inner cavity at the upper end of the aviation fuel tank; a mounting bracket is vertically mounted on the outer edge of the upper end of the aviation fuel tank; symmetrical second rotating grooves are formed in the left arc side face and the right arc side face of the connecting position of an upper end boss of the aviation fuel tank and the pressurizinginsertion pipe. The device has the beneficial effects that through cooperation of the lower inserting pipe of the buffer box, on the premise of preventing oil from flowing back, buffering of air inletpressurization is achieved, and through cooperation with the throttling valve, the pressurization rate is effectively controlled; by arranging the lining pipe driven by the motor, communication between the second through hole and the third through hole is achieved, the process of needing rapid pressurization is achieved, the pressurization rate is increased, the buffer time needed by pressurization is shortened, and the airplane can run more stably.

    本发明涉及航空飞机油箱技术领域,具体为一种机翼内置式航空油箱加压装置,包括航空油箱,航空油箱的上端内腔插接安装有加压插管,航空油箱的上端外缘竖直安装有安装支架,航空油箱的上端凸台与加压插管连接位置的左右圆弧侧面设置有相互对称的第二旋转槽,有益效果为:本发明通过设置缓冲箱盒下插管的配合,在防止油液回流的前提下,实现对进气增压进行缓冲,配合节流阀从而实现对加压速率进行有效的控制;通过设置电机驱动的内衬管,实现第二通孔与第三通孔之间的连通,实现在需要快速加压的过程,提高增压速率,减少增压需要的缓冲时间,使得飞机运行更加稳定。
