The invention relates to a self-sealing valve and an aircraft storage tank. The self-sealing valve comprises a valve body, a top plug, a plug, a first plugging piece, a second plugging piece and an elastic piece, the top plug, the plug and the valve body are coaxially arranged in the valve body, and the first plugging piece is arranged at the outlet end of the valve body and used for sealing the valve body; the second plugging piece is arranged at the inlet end of the valve body, abuts against the plug and is used for sealing the valve body when the self-sealing valve is idle. The elastic piece is arranged between the first plugging piece and the top plug and used for providing elastic force for the top plug. A good passage can be provided during filling of the storage tank, the device is automatically closed after filling is completed, the safety of the storage tank in the working process is improved, the device is different from a common filling port cover, a sealing element cannot be lost due to related operation in the filling process and does not need to be taken down, and meanwhile better air tightness and better adaptability to the flexible storage tank are achieved.

    本发明涉及一种自封阀及飞行器储箱。自封阀包括阀体、顶塞、堵塞、第一封堵件、第二封堵件和弹性件,其中,所述顶塞和堵塞与所述阀体同轴向设置在其内部,所述第一封堵件设置在所述阀体的出口端,用于密封所述阀体;所述第二封堵件设置在所述阀体的入口端且与所述堵塞抵接,用于在所述自封阀空闲时密封所述阀体;所述弹性件设置在第一封堵件和所述顶塞之间,用于对所述顶塞提供弹性力。本发明在储箱加注时能提供良好的通路,加注完成后装置自行封闭,提高了储箱工作过程的安全性,区别于一般加注口盖,密封元件不会因加注过程的相关操作而遗失更无需取下,同时还具有更好的气密性,对柔性储箱具有更好的适应性。
