Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a UPVC pipeline socket connection sealing combination device. Background Art

[0002] Pipe connection refers to connecting two or more pipes so that liquid or gas can flow in the pipes. Pipe connection is usually used in construction, industry, agriculture and municipal engineering. In the current UPVC material non-pressure or low-pressure pipe connection construction application, the socket connection method is one of the more commonly used connection methods. The pipe socket connection is to insert the end of one pipe into the mouth of another pipe and connect them through the friction between the pipes. Because UPVC pipes are acid and alkali resistant, corrosion resistant, rust-free, and scale-free, they can effectively avoid secondary pollution of water quality. In the actual construction process of the project, UPVC pipes are widely used in tap water piping projects and energy-saving irrigation piping projects.

[0003] However, there are still the following two problems in the use of UPVC:

[0004] 1. To prevent the liquid in the pipeline from freezing in winter, outdoor pipelines in the north are generally buried underground. During the construction process, construction workers often assemble the pipe sections on the ground, and then drag and lower the installed pipe sections into the pre-dug trenches. The above operations will cause the installed pipe sections to be dragged and displaced, thereby destroying the overall sealing of the pipeline;

[0005] 2. Conventional socket-and-spigot connections provide sealing through sealing rubber rings. However, since the sealing rubber rings are located inside the pipe section, the construction quality can usually only be controlled by the insertion depth of the pipe section. It is impossible to determine whether the sealing rubber rings are in the correct position to play a sealing role. After the pipeline is put into use, since the leaking points of the socket-and-spigot connection are generally located at the internal sealing rubber rings, it is difficult to repair them in a non-destructive manner. Usually, the only way to repair it is by cutting off the leaking part and re-welding it.

[0006] In order to solve the problem that the UPVC pipe is easily damaged in sealing and difficult to repair during use, the present application proposes a UPVC pipe socket connection sealing assembly device. Utility Model Content

[0007] In order to solve the above technical problems, the utility model proposes a UPVC pipe socket connection sealing combination device, which can effectively reduce the phenomenon of the pipe section with completed socket connection being dragged out during the construction process, reduce the probability of pipeline damage caused by dragging, and provide construction personnel with an auxiliary judgment method for completing the socket installation of the pipe section, saving the repair cost and time after the pipeline is put into use.

[0008] The technical solution to achieve the purpose of the utility model is: a UPVC pipe socket connection sealing combination device, including a pipe socket end and a pipe spigot end, a socket end sealing rubber ring is arranged in the pipe socket end, a spigot end sealing rubber ring is arranged in the pipe spigot end, the socket end sealing rubber ring includes a fixed part and a movable part, a socket end built-in magnet and a socket end check structure are respectively arranged in the movable part, and a spigot end check structure and a socket end built-in magnet are respectively arranged in the spigot end sealing rubber ring.

[0009] In some embodiments, the movable part is composed of an upper and lower part, the movable part in the lower part is fixed to the pipe wall by the pressure between the pipes, and the built-in magnet at the socket end is located in the movable part in the upper part.

[0010] In some embodiments, the fixed portion and the movable portion are an integral structure.

[0011] In some embodiments, the socket end check structure and the plug end check structure can engage with each other and are both arranged on the connection surface of the corresponding sealing rubber ring.

[0012] In some embodiments, a sticky material is disposed on the outer side of the sealing rubber ring at the socket end.

[0013] Compared with the prior art, the utility model has the following significant advantages:

[0014] Firstly, the utility model is composed of two parts of sealing rubber rings, which bite each other on the contact surface and are provided with corresponding non-return structures, which effectively reduce the phenomenon of the pipe section completed by the socket being dragged out during the construction process, and reduce the probability of pipeline damage caused by dragging;

[0015] Second, the utility model uses magnet adsorption between two parts of the sealing rubber ring as a sign that the socket connection is installed in place, which can provide construction personnel with an auxiliary judgment method for completing the socket installation of the pipe section. After the sealing rubber ring is installed, it can be used as a sealant filling channel leading to the outside. In the event of joint leakage during use, it can be quickly repaired by filling with sealant, saving the repair cost and time after the pipeline is put into use;

[0016] The invention solves the problem that the existing UPVC pipes are difficult to repair due to the easy occurrence of sealing damage and pipe damage during installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] The utility model provides a UPVC pipe socket connection sealing assembly device through improvement. The technical solution of the utility model is:

[0026] like Figure 1 As shown, a UPVC pipe socket connection sealing assembly device includes a pipe socket end 1 and a pipe spigot end 2, a socket end sealing rubber ring is arranged in the pipe socket end 1, a spigot end sealing rubber ring is arranged in the pipe spigot end 2, the socket end sealing rubber ring includes a fixed part 4 and a movable part 5, the fixed part 4 and the movable part 5 are both located in a groove in the pipe socket end 1, and their relative positions with the pipe socket end 1 are ensured by friction, a socket end built-in magnet 6 and a socket end non-return structure 7 are respectively arranged in the movable part 5, a spigot end non-return structure 9 and a socket end built-in magnet 10 are respectively arranged in the spigot end sealing rubber ring 3, the non-return structure can prevent the pipe from being dragged back during transportation, and during installation, the socket end built-in magnet 6 and the socket end non-return structure 7 are directly placed inside during the rubber ring manufacturing process so as to be directly shaped.

[0027] like Figure 2-Figure 3As shown, in one embodiment, the movable part 5 is composed of an upper and lower part. The lower movable part 5 is fixed to the pipe wall by the pressure between the pipes. The built-in magnet 6 at the socket end is located in the upper movable part 5. After the pipe is installed in place, the two magnets can be attracted together by magnetic force. After being put into use and passing water, the pressure between the rubber rings is further ensured by water pressure.

[0028] The fixed part 4 and the movable part 5 are an integrated structure. When the rubber ring is installed inside the pipe, the upper and lower parts of the movable part 5 can be combined together, which is convenient for construction workers to install and reduces the possibility of the rubber ring being damaged due to violent operation by construction workers during the installation process.

[0029] The socket end check structure 7 and the spigot end check structure 9 can engage with each other and are both arranged on the connection surface of the corresponding sealing rubber ring. After the pipeline is assembled, they can prevent backdraft under the pressure between the pipe walls.

[0030] like Figure 4 As shown, in one embodiment, a sticky material 8 is provided on the outside of the sealing rubber ring 3 at the socket end, and the sealing rubber ring 3 at the socket end is connected to the pipe socket end 2 through the sticky material 8. Its function is to facilitate fixing it on the groove of the pipe socket during the installation of the rubber ring, and at the same time, it can avoid displacement during the magnetic adsorption of the rubber ring at the socket. Since this position does not contact the medium in the pipe after the socket installation of the pipe is completed, it will not cause pollution to the pipe.

[0031] The specific working method is: when the UPVC pipe socket connection sealing assembly device is used, first insert the socket end sealing rubber ring into the corresponding position in the UPVC pipe, then connect the socket end sealing rubber ring 3 with the groove of the UPVC pipe socket end through the viscous material 8, insert the UPVC socket end into the socket end, and the socket section needs to face the water flow direction to ensure the reliability of the pipe socket connection. The two pipes are inserted into the appropriate position, and the socket end built-in magnet 10 and the socket end built-in magnet 6 are sucked together to complete the socket connection of the pipe section; after installation, the socket end sealing rubber ring and the socket end sealing rubber ring 3 can be temporarily connected through the magnetic force between the socket end built-in magnet 6 and the socket end built-in magnet 10, and the socket end check structure 7 and the socket end check structure 9 can be used to prevent the pipe from being accidentally dragged back before water is passed. After water is passed through the UPVC pipe, the connection effect can be further enhanced by the pressure of the liquid in the pipe.

[0032] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
