Drawings
Fig. 1 is a schematic view of the split structure of the present invention;
FIG. 2 is a schematic view of the assembly structure of the present invention;
fig. 3 is a schematic cross-sectional view of an alternative embodiment of the heat shrinkable sleeve of the present invention.
Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to fig. 1, the plastic inspection well sealing and connecting mechanism provided by the present invention comprises a plastic inspection well 1, a pipeline 3 and a heat shrinkable sleeve 4. Wherein:
the plastic inspection well 1 comprises a well seat 11, a well body 12 is arranged on the well seat, a branch pipe 13 communicated with the well body 12 is arranged on the side wall of the well body 12, a connecting pipe 14 with the pipe diameter smaller than that of the branch pipe 13 is formed at the end part of the branch pipe 13, namely, a stepped structure is formed at the connecting part of the branch pipe 13 and the connecting pipe 14.
The pipe 3 is sleeved on the connecting pipe 14, and the end part of the pipe 3 is abutted on the end part of the branch pipe 13.
The heat shrinkable sleeve 4 is sleeved on the outer sides of the branch pipe 13 and the pipeline 3.
Under the contraction and extrusion of the heat shrinkable sleeve 4, the pipe 3 presses the connecting pipe 14 inward, thereby improving the sealability between the pipe 3 and the connecting pipe. Furthermore, the end of the pipe 3 abuts against the end of the branch pipe 13, which further improves the sealing between the pipe 3 and the connecting pipe.
Optionally, in order to further improve the sealing performance, the present invention further includes a sealing ring 2 which is hermetically assembled between the pipe 3 and the connecting pipe 14. In some preferred embodiments, the sealing ring 2 is a conical sealing ring, the outer diameter of which gradually increases along the fluid flow direction (indicated by arrows in the figure), and the sealing ring 2 is partly sleeved on the connecting pipe 14 and partly extends outwards from the connecting pipe 14, thereby. Along with the flowing of the fluid, the part of the sealing ring 2 extending out of the connecting pipe 14 expands outwards and presses the inner wall of the pipeline 3, thereby further improving the sealing performance, and optionally, a plurality of rings of connecting ribs protruding out of the outer wall of the connecting pipe 14 are formed on the outer wall of the connecting pipe 14. The connecting ribs can enhance the connecting strength between the heat shrinkable sleeve 4 and the connecting pipe 14 and prevent the heat shrinkable sleeve 4 from falling off from the connecting pipe 14.
Optionally, the conduit 3 is a helical telescopic tube. The pipeline 3 is set as a spiral telescopic pipe, so that the connection strength between the heat-shrinkable sleeve 4 and the pipeline 3 can be improved, the heat-shrinkable sleeve 4 is prevented from falling off from the pipeline 3, and the pipeline 3 can be stretched and bent.
Optionally, in order to ensure the supporting performance of the wellbore 12, as shown in fig. 1, a grid-shaped supporting rib is arranged on the outer wall of the wellbore 12.
Alternatively, as shown in fig. 3, the heat shrinkable sleeve 4 is a laminated structure including a polyolefin substrate layer 41, and a hot melt layer 42 and a solid epoxy coating layer 43 sequentially disposed on the polyolefin substrate layer 41. After the heat shrinkable sleeve 4 is sleeved on the outer sides of the branch pipe 13 and the pipeline 3, the heat shrinkable sleeve 4 is radially shrunk, and after the hot melt layer 42 is melted, the heat shrinkable sleeve 4 is integrally and uniformly wrapped outside the connection part of the branch pipe 13 and the pipeline 3, so that a sealing structure is formed between the heat shrinkable sleeve and the branch pipe 13 and the pipeline 3. In addition, as the base material layer of the heat shrinkable sleeve 4 is made of polyolefin material, the corrosion resistance of the heat shrinkable sleeve 4 can be obviously improved, so that the service life of the heat shrinkable sleeve 4 is prolonged.
Of course, various existing heat shrinkable sleeves suitable for sealing pipelines can be adopted as the heat shrinkable sleeve 4 of the present invention.
The invention has been described above with a certain degree of particularity and detail. It will be understood by those of ordinary skill in the art that the description of the embodiments is merely exemplary and that all changes that may be made without departing from the true spirit and scope of the present invention are intended to be within the scope of the present invention. The scope of the invention is defined by the appended claims rather than by the foregoing description of the embodiments.
