The high-pressure large-flow electromagnetic valve mainly comprises a high-pressure valve body 1, an electromagnetic pilot valve 2, a high-pressure valve core 3, a high-pressure valve end cover 4, a spring 5, a throttling plug 6 and the like. The closing function of the electromagnetic valve is completed only by making the liquid in the high-pressure liquid inlet cavity not return to the liquid outlet side. The high-pressure liquid pressure is 40MPa, and the requirements on the movement speed of the high-pressure valve end cover 4, the electromagnetic pilot valve 2, the high-pressure valve core 3 and the like are very high. Because the nominal diameter of the electromagnetic pilot valve 2 is 2mm, the diameter of the orifice in the center of the throttle plug 6 is smaller than the aperture of the electromagnetic pilot valve 2, and the high-pressure valve core 3 can be smoothly opened or closed. The size of the throttle hole in the center of the throttle plug 6 is related to the movement speed of the high-pressure valve core 3 and the impact force of the high-pressure valve core 3 on the high-pressure valve body 1, so the proportional relation between the throttle plug 6 and the diameter of the high-pressure valve core 3 and the diameter of the electromagnetic pilot valve 2 is very important.

When the electromagnetic pilot valve 2 is electrified, the electromagnetic pilot valve 2 is in a closed state, liquid enters the high-pressure valve body 1 and the throttle plug 6 from the high-pressure liquid inlet 7, the body in the throttle hole of the throttle plug 6 enters the electromagnetic pilot valve 2, the electromagnetic pilot valve 2 is in a closed state, the liquid cannot flow into the high-pressure liquid outlet 8 through the electromagnetic pilot valve 2, the pressure in the closed space at the rear end of the high-pressure valve core 3 is higher and higher, the forward moving force of the high-pressure valve core 3 is higher and higher, and after the backward force of the liquid on the high-pressure valve core 3 is exceeded, the high-pressure valve core 3 moves forward until the high-pressure valve core 3 is completely closed (the high-pressure liquid inlet 7 and the high-pressure liquid outlet 8 cannot be communicated through a valve core cavity).
