Optionally, there are a plurality of the compression rings.
Through adopting above-mentioned technical scheme, a plurality of clamp rings seal the drain pipe jointly, increase sealed effect.
Optionally, both ends of the compression ring are provided with a reinforcing part.
Through adopting above-mentioned technical scheme, the clamp ring receives the protection of rib when warping, prevents that the clamp ring from breaking off when warping.
Optionally, the outer annular surface of the main body ring is provided with a deformation hole.
Through adopting above-mentioned technical scheme for main part ring is receiving easier deformation when the extrusion, and the degree of deformation is bigger.
In summary, the present application includes at least one of the following beneficial technical effects:
1. the insert ring is inserted into the water through opening, and continuously goes deep into the water through opening along with the increase of the extrusion force on the rubber ring, so that the blocking effect of the whole rubber ring on the water through opening is improved;
2. the outer ring surface of the insert ring is set to be the inclined surface, so that the insert ring is easier to insert into the water through opening and easier to deform inside the water through opening;
3. the sealing effect between the rubber ring and the drain pipe is improved by arranging the compression ring;
4. through setting up the deformation hole, make things convenient for the rubber circle to take place to warp.

Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses an elastic rubber ring for inspection well sealing. Referring to fig. 1, the elastic rubber ring for sealing an inspection well includes a main body ring 1, an insert ring 2 protrudingly provided on the main body ring 1, and a compression ring 3 protrudingly provided on an inner circumferential surface of the main body ring 1 and an inner circumferential surface of the insert ring 2. When using the rubber circle to carry out the shutoff to the limbers on the well casing, will insert ring 2 and aim at the limbers, and establish the rubber circle cover on the drain pipe, insert the drain pipe in the limbers, then use flange extrusion fixed rubber circle for insert ring 2 and insert in the limbers, along with the increase of flange extrusion force, insert ring 2 continuous deep into the limbers, increase the whole shutoff effect to the limbers of rubber circle.
Referring to fig. 2 and 3, a plurality of deformation holes 11 are formed in the outer circumferential surface of the main body ring 1, and the plurality of deformation holes 11 are arranged at equal intervals along the circumferential direction of the main body ring 1. The deformation hole 11 is a blind hole.
The insert rings 2 are arranged on the end surfaces of two sides of the main body ring 1, two insert rings 2 are arranged on the main body ring 1, and the two insert rings 2 are symmetrically arranged along the main body ring 1. The diameter of the outer ring of the insert ring 2 is smaller than that of the outer ring of the main body ring 1, the diameter of the inner ring of the insert ring 2 is the same as that of the inner ring of the main body ring 1, and the insert ring 2 is concentric with the main body ring 1. The outer annular surface of the insert ring 2 is an arc-shaped surface, and the diameter of one side of the insert ring 2 connected with the main body ring 1 is larger than the diameter of one side of the insert ring 2 departing from the main body ring 1. Wherein, after the outer loop of inserting ring 2 was the arcwall face, inserted ring 2 had two outer loop diameters, divided into little outer loop diameter and big outer loop diameter, and little outer loop diameter is less than the aperture of water service mouth, and big outer loop diameter is greater than the aperture of water service mouth.
