The invention provides a normally-closed high-air-pressure electromagnetic valve for an aircraft brake system, and belongs to the technical field of brake systems, a screw plug of the electromagnetic valve is located at the lower end in a cavity of a shell, an air inlet reset spring is located in an air inlet cavity of the screw plug, an air inlet valve assembly is located on the air inlet reset spring, and an air inlet valve seat is located on the air inlet valve assembly; a hemispherical sealing structure of the air inlet valve assembly is tightly connected with a conical surface of an air inlet valve seat to form a sealing pair, the air inlet valve seat is positioned on the top surface of a cavity of the shell, a piston reset spring is positioned in a groove of the air inlet valve seat, a positioning exhaust reset spring is positioned at the bottom end of the groove of the shell, and a piston is positioned on the piston reset spring. The exhaust valve assembly is located on the piston. The air inlet valve assembly, the air inlet valve seat, the piston and the exhaust valve assembly are sequentially connected and all located in the cavity of the shell. The lower end of the electromagnet assembly is located in the upper cavity of the shell. The electromagnetic valve is high in use pressure, long in service life and capable of meeting the use requirements of airplanes.
