Description
Technical Field
The utility model relates to an inspection shaft specifically is a connection structure of inspection shaft and pipeline.
Background
In the fields of communication cables, power cables, water supply and drainage and other infrastructure construction, inspection wells are indispensable equipment which is very important for the maintenance of pipes and the media therein.
Two ends of the inspection well are medium circulation holes for allowing a medium to enter or flow out, and when the length of the medium circulation hole needs to be prolonged, a pipeline needs to be installed in the medium circulation hole;
in conclusion, how to ensure the tightness between the pipeline and the inspection well becomes an urgent problem to be solved by researchers in the field.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to ensure the tightness of the pipeline and the inspection well;
in order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a connection structure of inspection shaft and pipeline, include: an inspection well; a pipe inserted into the medium flow hole of the inspection well; the sealing rubber ring seals a gap between the pipeline and the medium flow through hole; one end of the sealing rubber ring extends inwards to form a ring body, and the ring body is positioned on the end surface of the pipeline;
the sealing rubber ring is sleeved on the pipeline and then inserted into a medium circulation hole of the inspection well, so that the pipeline is hermetically connected with the inspection well; in addition, the inner circle of sealing rubber ring is provided with the ring body, and the ring body is located the terminal surface of pipeline, and when sealing rubber ring cover was established at the pipeline, the ring body was arranged in on the terminal surface of pipeline for sealing rubber ring follows the pipeline and inserts to the medium circulation downthehole of inspection shaft, and difficult slippage has guaranteed sealing performance between sealing rubber ring and the pipeline.
In order to further improve the sealing performance between the pipeline and the inspection well, the utility model adopts a plurality of annular bulges arranged on the outer wall of the sealing rubber ring in a protruding way; the annular bulge is abutted against the inner wall of the medium flow through hole;
and a plurality of flexible seals are formed between the pipeline and the medium circulation hole through the annular bulge, so that the sealing performance is further ensured.
In order not to interfere the flow of the medium in the pipeline, the inner diameter of the ring body is more than or equal to the inner diameter of the pipeline;
the thickness of the ring is thus smaller than the thickness of the pipe, so that the inner bore of the pipe does not interfere with the ring and the medium throughput is not affected.
The utility model has the advantages that: the utility model relates to a connecting structure of an inspection well and a pipeline, which realizes the sealing connection of the pipeline and the inspection well by sleeving a sealing rubber ring on the pipeline and then inserting the sealing rubber ring into a medium circulation hole of the inspection well; in addition, the inner circle of sealing rubber ring is provided with the ring body, and the ring body is located the terminal surface of pipeline, and when sealing rubber ring cover was established at the pipeline, the ring body was arranged in on the terminal surface of pipeline for sealing rubber ring follows the pipeline and inserts to the medium circulation downthehole of inspection shaft, and difficult slippage has guaranteed sealing performance between sealing rubber ring and the pipeline.
Drawings
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is an enlarged view of FIG. 1A;
in the figure: 1-inspection well, 2-pipeline, 3-sealing rubber ring, 4-medium circulation hole, 5-ring body and 6-ring protrusion.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model relates to a connection structure of inspection shaft and pipeline, include: an inspection well 1; a pipe 2 inserted into a medium flow hole 4 of the inspection well 1; the sealing rubber ring 3 seals a gap between the pipeline 2 and the medium flow hole 4; one end of the sealing rubber ring 3 extends inwards to form a ring body 5, and the ring body 5 is positioned on the end face of the pipeline 2;
the sealing rubber ring is sleeved on the pipeline and then inserted into a medium circulation hole of the inspection well, so that the pipeline is in sealing connection with the inspection well; in addition, the ring body is arranged on the inner ring of the sealing rubber ring, the ring body is positioned on the end surface of the pipeline, and when the sealing rubber ring is sleeved on the pipeline, the ring body is arranged on the end surface of the pipeline, so that the sealing rubber ring is inserted into a medium circulation hole of the inspection well along with the pipeline, the sealing rubber ring is not easy to slip off from the pipeline, and the sealing performance is ensured;
as shown in FIG. 1, only the pipeline is shown to be communicated with the medium circulation hole on one side of the inspection well, the ring body and the sealing rubber ring are made of the same material, and the ring body and the sealing rubber ring form a sealing structure with an L-shaped section.
As shown in fig. 2, in order to further improve the sealing performance between the pipeline and the inspection well, the utility model adopts a plurality of annular protrusions 6 which are convexly arranged on the outer wall of the sealing rubber ring 3; the annular bulge 6 is abutted against the inner wall of the medium flow hole 4;
a plurality of flexible seals are formed between the pipeline and the medium circulation hole through the annular bulge, so that the sealing performance is further ensured;
as shown in fig. 1 and 2, in order not to interfere with the flow of the medium in the pipeline, the inner diameter of the ring body 5 is greater than or equal to the inner diameter of the pipeline 2;
the thickness of the ring is thus smaller than the thickness of the pipe, so that the inner bore of the pipe does not interfere with the ring and the medium throughput is not affected.
The utility model relates to a connecting structure of an inspection well and a pipeline, which realizes the sealing connection of the pipeline and the inspection well by sleeving a sealing rubber ring on the pipeline and then inserting the sealing rubber ring into a medium circulation hole of the inspection well; in addition, the inner circle of sealing rubber ring is provided with the ring body, and the ring body is located the terminal surface of pipeline, and when sealing rubber ring cover was established at the pipeline, the ring body was arranged in on the terminal surface of pipeline for sealing rubber ring follows the pipeline and inserts to the medium flow hole of inspection shaft, and difficult slippage has guaranteed sealing performance between sealing rubber ring and the pipeline in, sealing rubber ring and the pipeline.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the description, and must be determined according to the scope of the claims.
