[0007] Preferably, the inner side of the compensation ring protrudes from the inner wall of the base ring and is provided with a plane.

[0008] Preferably, an auxiliary groove is further provided on the outer side of the base ring.

[0009] Preferably, a plurality of groups of reinforcing flanges are provided on the upper and lower sides of the base ring body, and the reinforcing flanges are provided around the first connecting tube and the second connecting tube.

[0010] (III) Beneficial effects

[0011] Compared with the prior art, the utility model provides a convenient-to-use sealing ring having the following features:

[0012] Beneficial effects:

[0013] The easy-to-use sealing ring has a compensation ring arranged on the inner side of the base ring. Initially, if the inner diameter of the base ring matches the material, the cavity in the compensation ring is not filled with filler. At this time, the compensation ring in contact with the material is squeezed by the material, and the cavity is compressed, thereby ensuring its close connectivity with the material. If the inner diameter of the base ring is slightly larger than the material, the sealing cap is opened, liquid is introduced through the corresponding connecting pipe, the corresponding connecting pipe is exhausted, and then the sealing is performed to ensure that the cavity is filled, the inner wall of the compensation ring is stably in contact with the material, thereby ensuring its stability in use. It can be connected with materials with a certain outer diameter, thereby ensuring its stability in use, and there is no need to replace the sealing ring of the corresponding specification, thereby ensuring easy use.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 A sealing ring that is easy to use includes a sealing ring body, wherein the sealing ring body includes a base ring 1, a compensation ring 2, a first connecting tube 3 and a second connecting tube 4, the compensation ring 2 is embedded in the base ring 1, a cavity is provided in the compensation ring 2, one end of the first connecting tube 3 and the second connecting tube 4 are both connected through the cavity, and the other ends of the first connecting tube 3 and the second connecting tube are both connected through the base ring 1 and are provided with a sealing cap 5.

[0019] During actual use, if the inner diameter of the base ring 1 matches the material, the cavity is squeezed to ensure the sealing of the equipment. If the inner diameter of the base ring 1 is slightly larger than the material, before assembly, if the cavity is filled with liquid, open the two sets of sealing caps 5, the first connecting pipe 3 is filled with liquid, and the second connecting pipe 4 is exhausted. If pressurization is required, the second connecting pipe 4 is closed after the exhaust is completed. If the cavity is filled with gas, the sealing cap 5 on the second connecting pipe 4 is closed, and the first connecting pipe 3 is closed through the corresponding sealing cap 5 after the air is taken in. The cavity is filled, and then the sealing ring body is assembled, and the inner wall of the compensation ring 2 is in contact with the material.
