[0006] The inside of the second sealing ring is set with buffer cavity, and the inside of the buffer cavity is fixedly connected with buffer spring.

[0007] According to the high pressure combined sealing ring, the fixed lug is "hemispheroid".

[0008] According to the high pressure combined sealing ring, the fixed slot is "hemispherical slot".

[0009] According to the high pressure combined sealing ring, the first sealing ring is fixedly connected with the second sealing ring by inserting block, fixed slot, inserting slot, installation slot, reset spring and fixed lug.

[0010] Compared with the prior art, the utility model has the advantages that:

[0011] 1. The high-pressure combined sealing ring, through the setting of the plug-in block, the fixed slot, the plug-in slot, the installation slot, the reset spring and the fixed protrusion, the first sealing ring can be conveniently disassembled and replaced, and when the first sealing ring is seriously aged, the first sealing ring can be replaced without replacing the entire sealing ring, thereby saving costs.

[0012] 2. The high-pressure combined sealing ring, through the setting of the buffer cavity and the buffer spring, the buffering effect of the sealing ring is improved, and the elasticity of the sealing ring is increased, thereby achieving good use effect.

[0013] The additional aspects and advantages of the present application will be partially given in the following description, and some will become apparent from the following description, or be understood through the practice of the present application. BRIEF DESCRIPTION OF DRAWINGS
