Description

Technical Field

[0001] This utility model belongs to the field of municipal drainage engineering technology, specifically relating to a leak-proof drainage pipe network sealing connection structure. Background Technology

[0002] Leak-proof drainage network sealing connection structure is a sealing design for drainage pipes. It prevents sewage from leaking into the external environment through a sealing mechanism, including sealing rings, connection structures and protective components, to ensure long-term stable sealing at the connection.

[0003] Existing leak-proof drainage pipe network sealing connection structures generally use flanges with sealing elements and bolts to achieve a seal. This structure requires disassembling and assembling each bolt individually, which is time-consuming and cumbersome. Moreover, relying on a single sealing element and lacking a targeted external seepage prevention design, it is easy for external impurities and groundwater to seep into the pipe. Therefore, a leak-proof drainage pipe network sealing connection structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a leak-proof sealing connection structure for drainage pipe networks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof drainage pipe network sealing connection structure, comprising an inlet pipe, a sealing connecting pipe, an outlet pipe, and fixing bolts. The sealing connecting pipe has two connecting slots inside. A leak-proof sealing ring is fixedly connected to the inner wall of the sealing connecting pipe. A flow-guiding protection plate is fixedly connected to the surface of the leak-proof sealing ring. The inner walls of the two connecting slots are respectively provided with internal threaded grooves. External threaded rings are threadedly connected to the inner walls of the two internal threaded grooves. A sealing ring is fixedly connected to one end of each of the two external threaded rings. A first clamp is fixedly connected to one end of each of the two sealing rings. A second clamp is fixedly connected to one end of each of the two sealing rings.

[0006] By setting up the above structure, the two connecting slots can quickly connect the inlet pipe and the outlet pipe, simplifying installation. Then, the external threaded ring and the internal threaded groove can be used to achieve initial fixation and pre-sealing of the connecting parts, making operation convenient. At the same time, the double sealing structure composed of the leak-proof sealing ring and the sealing ring can enhance the sealing performance, prevent internal sewage leakage and external impurities from seeping in, and improve reliability. In addition, the cooperation of the first clamp, the second clamp and the fixing bolt can further tighten the sealing structure, so that the components fit tightly, strengthen the sealing effect and ensure the connection stability, and avoid sealing failure due to vibration or displacement.

[0007] As a preferred embodiment, one of the connecting slots is connected to the inlet pipe, and the other connecting slot is connected to the outlet pipe.

[0008] As a preferred embodiment, the flow guide protection plate is located outside the leak-proof sealing ring.

[0009] As a preferred embodiment, the two external threaded rings are respectively connected to the sealing connecting pipe thread.

[0010] As a preferred embodiment, the two sealing rings are located inside the sealing connecting pipe.

[0011] As a preferred embodiment, one end of each of the two first clamps is attached to one end of the sealing connecting pipe, and one end of each of the two second clamps is attached to one end of the sealing connecting pipe, with the first clamps positioned above the second clamps.

[0012] As a preferred embodiment, the fixing bolt is inserted and connected to the first clamp, and the fixing bolt is inserted and connected to the second clamp.

[0013] By setting up a flow guide plate, water can be guided to flow smoothly, reducing impact and wear on the leak-proof sealing ring, extending its service life, and maintaining long-term sealing performance.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting two connecting slots, enables quick connection between the inlet and outlet pipes, simplifying installation. Subsequently, the external threaded ring and internal threaded groove cooperate to achieve initial fixation and pre-sealing of the connecting components, making operation convenient.

[0024] Please see Figure 1-4 This utility model provides a leak-proof drainage pipe network sealing connection structure, including an inlet pipe 1, a sealing connecting pipe 2, an outlet pipe 3, and fixing bolts 12. The sealing connecting pipe 2 has two connecting slots 4 inside. A leak-proof sealing ring 5 is fixedly connected to the inner wall of the sealing connecting pipe 2. A flow-guiding protection plate 6 is fixedly connected to the surface of the leak-proof sealing ring 5. The inner walls of the two connecting slots 4 each have internal threaded grooves 7. External threaded rings 8 are threadedly connected to the inner walls of the two internal threaded grooves 7. A sealing ring 9 is fixedly connected to one end of each of the two external threaded rings 8. A first clamp 10 is fixedly connected to one end of each of the two sealing rings 9. A second... The two clamps 11, with two connecting slots 4, enable quick connection between the inlet pipe 1 and the outlet pipe 3, simplifying installation. Then, the external threaded ring 8 and the internal threaded groove 7 work together to achieve initial fixation and pre-sealing of the connecting parts, making operation convenient. At the same time, the double sealing structure composed of the leak-proof sealing ring 5 and the sealing ring 9 can enhance the sealing performance, prevent internal sewage leakage and external impurities from seeping in, and improve reliability. In addition, the cooperation of the first clamp 10, the second clamp 11 and the fixing bolt 12 can further tighten the sealing structure, so that the components fit tightly, strengthen the sealing effect and ensure the connection stability, and avoid sealing failure due to vibration or displacement.

[0025] One connecting slot 4 is inserted and connected to the water inlet pipe 1, and the other connecting slot 4 is inserted and connected to the water outlet pipe 3.

[0026] The flow guide protection plate 6 is located outside the leak-proof sealing ring 5.

[0027] The two external threaded rings 8 are respectively threadedly connected to the sealing connecting pipe 2.

[0028] The two sealing rings 9 are located inside the sealing connecting pipe 2.

[0029] One end of each of the two first clamps 10 is attached to one end of the sealing connecting pipe 2, and one end of each of the two second clamps 11 is attached to one end of the sealing connecting pipe 2. The first clamps 10 are located above the second clamps 11.

[0030] The fixing bolt 12 is inserted and connected to the first clamp 10, and the fixing bolt 12 is inserted and connected to the second clamp 11. By setting the flow guide protection plate 6, the water flow can be guided to pass smoothly, reducing the impact and wear on the leak-proof sealing ring 5, extending the service life, and maintaining long-term sealing performance.

[0031] Working principle and usage process of this utility model:

[0032] Insert the inlet pipe 1 and outlet pipe 3 into the two connecting slots 4 inside the sealing connecting pipe 2, respectively. Then rotate the external threaded ring 8 to make it threadedly connect with the internal threaded groove 7 on the inner wall of the connecting slot 4. While achieving initial fixation, it drives the sealing ring 9 to press and seal. At the same time, the leak-proof sealing ring 5 inside the sealing connecting pipe 2 will form a double sealing structure with the sealing ring 9. Together with the first clamp 10, the second clamp 11 and the fixing bolt 12, the sealing structure is further tightened to the surface of the inlet pipe 1 and the outlet pipe 3, so that the components fit tightly. This not only enhances the sealing of the connection, but also ensures the stability of the connection between the inlet pipe 1, the outlet pipe 3 and the sealing connecting pipe 2. In addition, the flow guide plate 6 can guide the water flow smoothly and reduce the impact on the sealing structure. Ultimately, it ensures that internal sewage does not leak and external impurities do not seep in during the drainage process.
