Description

Technical Field

[0001] The present invention relates to the technical field of pipeline connection, and in particular to a connection device with a self-locking sealing structure for pipeline connection. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. When pipelines are in use, multiple groups of pipelines are generally required to be connected. Pipeline connection refers to connecting the prefabricated pipe sections into a complete system according to the requirements of the design drawings. In the construction of pipeline projects, different connection methods should be selected according to the material of the pipes used. Ordinary steel pipes have threaded connections, welding and flange connections. Seamless steel pipes, non-ferrous metals and stainless steel pipes are mostly welded and flanged. Cast iron pipes mostly use socket connections, and a few use flange connections. Plastic pipes mostly use threaded connections, bonding and hot-melt connections, etc. There are many forms of other non-metallic pipe connections.

[0003] When existing pipelines are connected daily, they are generally connected by flange screws, so a large number of tools are used for the connection, which makes the pipeline connection inconvenient. At the same time, after the connection, the pipeline connection will become loose after long-term use, which will cause poor sealing of the connection and cause liquid to leak through the connection. Therefore, a connection device with a self-locking sealing structure based on pipeline connection is urgently needed to solve the above problems. Summary of the invention

[0031] Furthermore, the positioning rod 13 is set to a rectangular structure, and a rectangular groove is opened inside the second connecting seat 17. The surface size of the positioning rod 13 is smaller than the inner wall size of the rectangular groove opened inside the second connecting seat 17.

[0035] Furthermore, the sealing ring 24 is set to a circular structure, and a circular groove is opened inside the second connecting seat 17, and the inner wall size of the circular groove opened inside the second connecting seat 17 is larger than the surface size of the sealing ring 24. The sealing ring 24 moves in the circular groove opened inside the second connecting seat 17, so that the first sealing rubber pad 12 and the surface of the second sealing rubber pad 30 are in conflict, thereby playing a role in sealing the connection between the first connecting seat 11 and the second connecting seat 17;

Through the external thread provided on the surface of the rotating rod 25, when the rotating rod 25 rotates, the rotating rod 25 can be moved inside the sealing ring 24, so that the moving block 26 can be pushed to slide inside the sealing ring 24;

[0037] Furthermore, the second limiting rod 27 is configured as a rectangular structure, and a sliding groove is provided on the surface of one side of the sealing ring 24 close to the filter screen 28, and the sliding groove provided on the surface of one side of the sealing ring 24 forms a sliding connection with the second limiting rod 27. The second limiting rod 27 slides in the sliding groove provided on the surface of one side of the sealing ring 24, which can facilitate the installation and disassembly of the filter screen 28.

[0038] Working principle: When the first connecting pipe 1 and the second connecting pipe 29 need to be connected, Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 6When the positioning rod 13 is inserted into the rectangular groove opened inside the second connecting seat 17, the first limiting rod 15 is squeezed and can be retracted into the interior of the positioning rod 13. At the same time, the first sealing rubber pad 12 is in conflict with the surface of the second sealing rubber pad 30, so that the first sealing rubber pad 12 can push the sealing ring 24 to move, so that the second telescopic rod 22 can be retracted into the interior of the first telescopic rod 20. When the first connecting seat 11 conflicts with the surface of the second connecting seat 17, the first limiting rod 15 can be reset and engaged by the elastic force of the first spring 16 itself. The first connecting tube 1 and the second connecting tube 29 can be connected inside the second connecting seat 17. When the first connecting seat 11 and the second connecting seat 17 need to be disassembled, an object is manually inserted into the inside of the fixed frame 18. The pushing rod 19 can be squeezed by the object to make the pushing rod 19 squeeze the first limiting rod 15. When the first limiting rod 15 is retracted into the inside of the positioning rod 13, the elastic force of the second spring 23 itself can push the second telescopic rod 22 to move, so that the sealing ring 24 can push the first connecting seat 11 away from the surface of the second connecting seat 17.

[0039] When the first connecting pipe 1 and the second connecting pipe 29 are in use, according to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 4 and attached Figure 5 The impeller 3 can be rotated by the impact of water flow. When the impeller 3 is rotating, the first driving rod 4 can be driven to rotate. When the first driving rod 4 is rotating, the first driving rod 4 can drive the second driving rod 5, so that the rotating disc 6 can be rotated. When the rotating disc 6 is rotating, the cleaning rod 10 can be driven to rotate on the surface of the filter 28 through the second rotating shaft 7. Impurities in the water flow can be filtered through the filter 28, and the filter 28 can be prevented from being blocked by the rotation of the cleaning rod 10. When the filter 28 needs to be replaced, according to the attached Figure 1 and attached Figure 7 By rotating the rotating rod 25, the rotating rod 25 can be moved away from the surface of the moving block 26. At this time, the second limiting rod 27 can be pulled to keep the second limiting rod 27 away from the surface of the filter screen 28. At this time, the filter screen 28 can be removed from the side of the second connecting pipe 29. When the filter screen 28 is installed on the side of the second connecting pipe 29, by rotating the rotating rod 25, the rotating rod 25 can push the moving block 26 to move inside the sealing ring 24, so that the second limiting rod 27 can be moved and the second limiting rod 27 can conflict with the surface of the filter screen 28, so that the filter screen 28 can be installed. The above is the entire working principle of the present invention.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
