Detailed implementation manner

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Such as Figures 1-5As shown in the figure, on the one hand, the present utility model provides a pipeline connection structure, which includes a main pipeline 1, an expansion joint 2, and a branch pipeline 3. The expansion joint 2 is located between the main pipeline 1 and the branch pipeline 3. Among them, the expansion joint 2 includes a joint sleeve 21 and a first socket interface 22 and a second socket interface 23 located at both ends of the joint sleeve 21. A limit retaining ring 24 is fixed on the inner wall of the joint sleeve 21 near the second socket interface 23, and a sealing ring 25 is placed on the limit retaining ring 24 of the joint sleeve 21. One end of the branch pipeline 3 is provided with an arc-shaped chamfer 31. The expansion joint 2 is connected to the main pipeline 1 through the first socket interface 22 of the joint sleeve 21, and the end of the branch pipeline 3 with the arc-shaped chamfer 31 is inserted into the second socket interface 23 of the joint sleeve 21 to realize the clamping connection between the branch pipeline 3 and the expansion joint 2. The expansion joint 2 provided by the present utility model can be applied to the connection of pipelines in the aeration system under different construction environments. After the main pipeline 1, the expansion joint 2, and the branch pipeline 3 are processed in the processing plant, they can be sent to the site for plugging and fixing, without the need for on-site hot work operations, reducing potential safety hazards. The connection between the expansion joint 2 and the branch pipeline 3 can be completed only by inserting connection, which requires lower quality requirements for construction personnel. It not only reduces labor costs and time costs but also improves construction efficiency. The expansion joint 2 is provided with a sealing ring 25 at the socket interface, which is beneficial to improving the sealing performance of the pipeline connection. Especially in the aeration system, it has good sealing performance for water and air, and can effectively prevent the leakage of gas and liquid. The expansion joint 2 and the branch pipeline 3 can be detachably plugged, which is convenient for subsequent maintenance, replacement, or transformation of the pipeline, avoiding the situation of traditional welding methods that require cutting and repairing the pipeline and then re-welding, reducing costs and workload. An arc-shaped chamfer 31 is provided at one end of the branch pipeline 3. The arc-shaped chamfer 31 is provided to prevent the sealing ring 25 from being scratched when the branch pipeline 3 is inserted into the joint sleeve 21, and the arc-shaped chamfer 31 is provided to facilitate the insertion of the branch pipeline 3 into the joint sleeve 21, making the plugging easier.

[0030] The sealing ring 25 of the present utility model is an annular part made of rubber, mainly used to isolate and prevent the leakage of liquid or gas, ensuring the sealing performance of the pipeline connection. The expansion joint 2 adds a sealing ring 25 on the basis of the traditional socket joint. During the connection process, the sealing ring 25 is placed at the limit retaining ring 24 of the joint sleeve 21. When the interface of the branch pipeline 3 with the arc-shaped chamfer 31 is inserted into the joint sleeve 21, the sealing ring 25 in the joint sleeve 21 is compressed and closely adheres to the arc-shaped chamfer 31 and the limit retaining ring 24 of the joint sleeve 21, thereby effectively preventing the leakage of liquid or gas from the interface between the branch pipeline 3 and the joint sleeve 21.

[0031] When the utility model is specifically implemented, a connecting pipe orifice is opened on the main pipeline 1. The expansion joint 2 is inserted into the connecting pipe orifice of the main pipeline 1 through the first socket interface 22 of the joint sleeve 21 and then welded and fixed, so as to realize the connection between the expansion joint 2 and the main pipeline 1. A limiting ring is fixed on the inner wall of the joint sleeve 21 and near the first socket interface 22. By setting the limiting ring, the installation and connection between the main pipeline 1 and the expansion joint 2 can be limited.

[0032] In the utility model, a retaining ring 26 is fixed on the circumferential outer wall of the joint sleeve 21, and the position of the retaining ring 26 corresponds to the position of the limiting clamping ring 24 on the inner wall of the joint sleeve 21.

[0033] As Figures 6-7 shown, on the other hand, the utility model also provides a support structure 4, including a support structure 4 for supporting the pipeline connection structure. The support structure 4 includes a support frame 41, a height adjustment component 42, and a support bracket 43. The height adjustment component 42 is arranged between the support bracket 43 and the support frame 41. One end of the height adjustment component 42 is connected to the support bracket 43, and the other end of the height adjustment component 42 passes through the support frame 41 and is fixed on the support frame 41. The support bracket 43 is fixed on the support frame 41 through the height adjustment component 42. The support bracket 43 is used for supporting the branch pipeline 3. When specifically implemented, the height adjustment component 42 of the utility model includes a screw rod 421, an adjusting nut 422, and a locking nut 423. The support frame 41 includes an upper support plate 411, a lower support plate 412, and a support column 413. The upper support plate 411 and the lower support plate 412 are fixedly arranged on both sides of the support column 413 in parallel. The upper support plate 411 and the lower support plate 412 are respectively provided with a first opening and a second opening. The adjusting nut 422 is threadedly connected with the screw rod 421. One end of the screw rod 421 is connected to the support bracket 43, and the other end of the screw rod 421 passes through the first opening and the second opening of the upper and lower support plates 412 of the support frame 41. The screw rod 421 is locked and fixed on the upper support plate 411 of the support frame 41 through the adjusting nut 422, and the screw rod 421 is locked and fixed on the lower support plate 412 of the support frame 41 through the locking nut 423. By rotating the locking nut 423 and the adjusting nut 422, the distance between the support bracket 43 on the screw rod 421 and the upper support plate 411 of the support frame 41 can be adjusted, so as to achieve the purpose of adjusting the height of the support bracket 43 and adapt to the pipeline supports of different heights.

[0034] The utility model also pads a rubber shock pad 431 at the upper end of the support bracket 43. The rubber shock pad 431 arranged above the support bracket 43 can be 10 mm, which can play a shock-absorbing role and avoid transmitting vibrations to the concrete structure ground when the pipeline system where the branch pipeline 3 is located operates.

[0035] In specific implementation, the support bracket 43 of the present utility model is designed as an arc structure, which is convenient to match the outer shape of the branch pipeline.

[0036] A support base 414 is fixed below the support column 413 of the present utility model.

[0037] In specific implementation, a pier 5 is provided below the main pipeline 1, and the main pipeline 1 is supported by the pier 5.

[0038] Such as Figure 1 shown, the installation operation of the pipeline connection structure of the present utility model is as follows:

[0039] Step 1) Fixing the support structure 4: Measuring and setting out the line, fixing the support structure 4. The installation point is accurately positioned through measuring and setting out the line, and the support structure 4 is fixed at the positioning installation point by using expansion bolts;

[0040] Step 2) Processing the pipeline: Pre-processing in the processing factory, welding the first socket interface 22 of the main pipeline 1 and the expansion joint 2; One end of the branch pipeline 3 is trimmed flat with a hand grinder and pliers to form an arc-shaped trimmed port 31 to avoid damaging the sealing ring 25 of the expansion joint 2 when installing the branch pipeline 3;

[0041] Step 3) Pipeline installation: Fixing the main pipeline 1 at one end of the expansion joint 2, placing the sealing ring 25 in the limit retaining ring 24 of the expansion joint 2, inserting and assembling the branch pipeline 3 with the arc-shaped trimmed port 31 at one end with the expansion joint 2 for the branch pipeline 3. The branch pipeline 3 is pushed forcefully towards the sealing ring 25 of the expansion joint 2 at the end with the arc-shaped trimmed port 31 until it is considered that the assembly is completed. The other end of the branch pipeline 3 is supported and fixed by the support structure 4.

[0042] The above has made a detailed description of the present utility model. The above description is only the preferred embodiment of the present utility model, and the scope of implementation of the present utility model cannot be limited.
