[0003] To solve the problems mentioned in the above background art, different-sized raised rings are used on the outside of the valve seat to play an anti-misassembly role, and at the same time, it can be closely matched with the mating parts to improve the stability of the product.

[0004] The technical solution of the utility model: A high-stability aluminum valve seat, including a valve seat, on the outside of which there are a plurality of raised rings with different sizes arranged axially; a groove is provided on the top surface of the valve seat, and cuts vertically penetrating the groove are provided on both sides of the valve seat near the top surface.

[0005] The outer diameter of the raised ring decreases gradually from the bottom surface to the top surface of the valve seat.

[0006] A hole is also provided at the bottom of the groove, and the groove and the hole form a stepped groove structure.

[0007] A through-hole groove is provided on the valve seat near the cut side, and the through-hole groove penetrates the groove and the hole.

[0008] A guiding surface is provided at the edge of the raised ring on the side of the cut.

[0009] The valve seat is made of space aluminum material.

[0010] The valve seat is designed for integrated processing.

[0011] An inclined cutting surface is provided at the outlet of the groove.

[0012] Compared with the prior art, the utility model provides a high-stability aluminum valve seat, which has the beneficial effects that different-sized raised rings are used on the outside of the valve seat to play an anti-misassembly role, and at the same time, it can be closely matched with the mating parts to improve the stability of the product.
