The invention relates an angle high pressure oxygen valve. The angle high pressure oxygen valve comprises a valve rod and an angle valve body, the lower end of the valve rod stretches into the valve body, the lower end of a lower valve rod is provided with a valve rod sealing face, and a valve body sealing face is arranged at the position where media of the valve body enter a channel. The valve rod sealing face and the valve body sealing face form an angle difference sealing pair. The valve rod sealing face and the valve body sealing face are both cones. The cone angle of the valve rod sealingface is greater than the angle cone of the valve body sealing face, and hardness difference exists between the valve rod sealing face and the valve body sealing face. The valve rod sealing face and the valve body sealing face form the angle form the angle difference sealing pair, and hardness difference exists between the valve rod sealing face and the valve body sealing face. When the valve is closed, the valve rod seal
