TECHNICAL FIELD
[0001] The utility model relates to the technical field of anti-seepage pipeline, especially to the anti-seepage pipeline for municipal water supply and drainage. BACKGROUND
[0002] In today's society, various industrial production, municipal construction and civil facilities and many other fields widely rely on pipeline systems to transport various fluid media, such as water, oil, natural gas, chemical raw materials, etc. As the key infrastructure in these systems, the sealing and stability of the connecting part of the pipeline directly affect the safety and efficient operation of the entire system. Once the sealing of the pipeline connection fails or is damaged due to external impact, not only may it cause leakage of the transported medium, leading to serious consequences such as resource waste and environmental pollution, but also may cause the entire transportation system to malfunction, resulting in huge economic losses and even endangering human life and safety.
[0003] The traditional pipeline connection sealing method usually uses single sealant filling or simple mechanical fastening structure. When relying only on sealant filling, although the sealant can provide a certain sealing effect at the initial installation, when the pipeline is subjected to external impact such as earthquakes, foundation settlement, pipeline surrounding construction vibration and other factors, causing displacement of the pipeline connection, the sealant is prone to cracking and falling off, thereby losing the sealing ability and causing medium leakage. While using mechanical fastening structure alone, such as the commonly used flange connection with bolt and nut fastening, although it can resist displacement to a certain extent, due to the lack of elastic buffer mechanism, when facing frequent or large external impact, the rigid connection structure is easy to cause stress concentration at the pipeline connection, which may eventually cause local deformation and rupture of the pipeline, and thus cannot guarantee long-term stable sealing and connection effect. In addition, some existing pipeline protection designs simply increase the thickness of the pipe wall, but ignore the construction of effective buffer and impact resistance structure inside the pipeline, so that the pipeline cannot effectively disperse and buffer the impact force when subjected to external pressure, further reducing the overall service life of the pipeline. To solve this technical problem, the present application provides an anti-seepage pipeline for municipal water supply and drainage. SUMMARY
[0004] The utility model discloses a municipal water supply and drainage anti-seepage pipeline, which fills sealant in the sealing filling groove of the outer wall of the sealing ring, and realizes dynamic sealing compensation by cooperating the lower sleeve, the upper sleeve and the sealing spring, thereby ensuring the sealing of the pipeline connection. At the same time, the spring strip is connected in a spiral shape on the outer wall of the inner wall and penetrates through the support ring, effectively buffering external impact, enhancing the resistance of the pipeline and prolonging the service life.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0006] The utility model discloses a municipal water supply and drainage anti -leakage pipeline, including the inner wall pipe, the outer wall of inner wall pipe is connected with the outer wall pipe through the protection subassembly, the front end fixed connection of inner wall pipe has the sealing ring no.
[0007] Further, the elastic assembly includes a sealing spring arranged on the outer wall of the fixed rod, and the outer wall of the fixed rod is provided with a circular limiting plate.
[0008] Further, the clamping assembly includes an upper clamping sleeve arranged on the outer wall of the top end of the fixed rod, and the bottom end of the fixed rod is provided with a lower clamping sleeve, and the inner walls of the inner periphery of the upper clamping sleeve and the lower clamping sleeve are both provided with mounting grooves.
[0009] Further, the clamping groove is arranged on the outer wall of the fixed block.
[0010] Further, the protection assembly includes a supporting ring fixedly connected to the outer wall of the inner wall pipe, and the outer wall of the inner wall pipe is provided with a spring strip, and the spring strip penetrates through the inside of the supporting ring.
[0011] Further, the supporting ring is arranged on the inner wall of the outer wall pipe to support the outer wall pipe.
[0012] Further, the sealing ring no. 1 and the sealing ring no. 2 are arranged in the inside of the mounting groove.
[0013] The utility model has the following beneficial effects:
[0014] 1、 in the utility model, the sealing ring no. 1 and the sealing ring no. 2 are filled with sealing glue in the sealing filling groove of the outer wall, then the lower clamping sleeve and the upper clamping sleeve are clamped on the outer wall of the sealing ring, and the circular limiting plate is rotated, the inner wall thread cooperates with the outer wall thread of the fixed rod to compress the sealing spring, so that the lower clamping sleeve and the upper clamping sleeve are tightly pressed on the outer wall of the sealing ring. This structure design can realize good sealing effect at the pipeline connection. Even if the pipeline connection is displaced due to external impact and other factors, the sealing spring can be compressed or reset, so that the lower clamping sleeve and the upper clamping sleeve are always tightly connected to the outer wall of the sealing ring, and the sealing property of the connection between the pipelines is always maintained.
[0015] 2、 The spring strip is connected in a spiral shape on the outer wall of the inner wall pipe, and penetrates through the inside of the support ring.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0023] Reference Figures 2-4The utility model provides a kind of embodiment: municipal water supply and drainage is prevented from leaking pipeline, including inner wall pipe 1, support ring 10 is fixedly connected in the outer wall of inner wall pipe 1, the outer wall of inner wall pipe 1 is provided with spring strip 11, spring strip 11 is through the inside of support ring 10, the front end of inner wall pipe 1 is fixedly connected with sealing ring two 12, the rear end of inner wall pipe 1 is fixedly connected with sealing ring one 3, the outer wall of sealing ring one 3 is equipped with clamping groove 15, the outer wall of sealing ring two 12 is fixedly connected with fixed block 5, the outer wall of fixed block 5 is fixedly connected with fixed rod 6, sealing spring 7 is arranged in the outer wall of fixed rod 6, the outer wall of fixed rod 6 is provided with circular limit plate 13, upper clamping sleeve 9 is arranged in the outer wall of the top end of fixed rod 6, the outer wall of the bottom end of fixed rod 6 is provided with lower clamping sleeve 8, the inner circumferential inner wall of lower clamping sleeve 8 and upper clamping sleeve 9 is equipped with mounting groove 14, clamping groove 15 is arranged in the outer wall of fixed block 5, to be used for the clamping of sealing ring one 3 and the outer wall of sealing ring two 12, the outer circumferential outer wall of sealing ring one 3 and sealing ring two 12 is equipped with sealing filling groove 4, the outer wall of fixed rod 6 is provided with screw thread;
[0024] Specifically, in the process of pipeline connection, first, the outer wall clamping groove 15 of sealing ring one 3 is clamped with the outer wall of fixed block 5. Then, the outer wall sealing filling groove 4 of sealing ring one 3 and sealing ring two 12 is filled with sealant. Next, the lower clamping sleeve 8 and the upper clamping sleeve 9 are clamped on the outer wall of sealing ring two 12 and sealing ring one 3 by using the mounting groove 14. By rotating the circular limit plate 13, the compression force is applied to the sealing spring 7 by the cooperation of the inner wall screw thread and the outer wall screw thread of the fixed rod 6, so that the lower clamping sleeve 8 and the upper clamping sleeve 9 are tightly attached to the outer wall of sealing ring two 12 and sealing ring one 3, realizing the sealed connection between multiple pipelines. When the pipeline connection is affected by external impact or other factors and displacement occurs, the sealing spring 7 will be compressed or reset, ensuring that the lower clamping sleeve 8 and the upper clamping sleeve 9 are always tightly connected to the outer wall of sealing ring one 3 and sealing ring two 12, maintaining the sealing of the pipeline connection. In the municipal drainage system, the pipeline will be impacted and compressed by the outside world during use. At this time, the support ring 10 and the spring strip 11 will be impacted and deformed. Since the spring strip 11 is connected in a spiral shape on the outer wall of the inner wall pipe 1 and penetrates the inside of the support ring 10, the inner wall pipe 1 can have better resistance when impacted, thereby prolonging the service life of the pipeline. In actual production, the spring strip 11 and the support ring 10 are sleeved on the outer wall of the inner wall pipe 1, protecting the outer wall of the inner wall pipe 1, ensuring that the inner wall pipe 1 can be affected by the deformation of the spring strip 11 and the support ring 10 when impacted by the outside world, thereby reducing the impact on the inner wall pipe 1.
[0025] Referring to Figure 1 , Figure 2 and Figure 4 , the support ring 10 is arranged on the inner wall of the outer wall pipe 2 to support the outer wall pipe 2, and the sealing ring one 3 and the sealing ring two 12 are arranged in the inside of the mounting groove 14;
[0026] Specifically, dynamic sealing compensation is achieved through the sealing spring 7 and the lower sleeve 8 and the upper sleeve 9. When the pipe connection is displaced due to external impact or vibration, the sealing spring 7 can automatically compress or reset to ensure that the sleeve is always tightly attached to the sealing ring, thereby maintaining the sealing performance. The sealing filling groove 4 design of the sealing ring one 3 and the sealing ring two 12 not only provides a stable filling space for the sealing glue, but also increases the contact area between the sealing glue and the sealing ring through the groove structure, further enhancing the sealing effect. In addition, the shape and size of the sealing filling groove 4 can be optimized according to actual use, which can ensure that the sealing glue is evenly distributed when stressed, avoiding sealing failure due to local stress concentration; the lower sleeve 8 and the upper sleeve 9 are tightly matched with the outer walls of the sealing ring one 3 and the sealing ring two 12 through the installation groove 14, which not only facilitates installation and removal, but also forms a double-sealing barrier at the pipe connection. The spring strip 11 is connected in a spiral shape to the outer wall of the inner wall pipe 1 and penetrates the inside of the support ring 10, so that the spring strip 11 can produce elastic deformation when impacted, effectively absorbing and dispersing impact energy; the support ring 10 plays an important supporting and guiding role inside the pipe. When the pipe is impacted by external impact, the support ring 10 can evenly distribute the impact force to the spring strip 11, avoiding local stress concentration leading to pipe rupture.
[0027] Working principle: First, the clamping groove 15 on the outer wall of the sealing ring one 3 is clamped on the outer wall of the fixed block 5, then the sealing filling groove 4 on the outer wall of the sealing ring one 3 and the sealing ring two 12 is filled with the required sealing glue, then the lower sleeve 8 and the upper sleeve 9 are clamped on the outer wall of the sealing ring two 12 and the sealing ring one 3 through the installation groove 14, and then the sealing spring 7 is compressed by rotating the circular limiting plate 13 and the cooperation between the inner wall threads of the circular limiting plate 13 and the outer wall threads of the fixed rod 6, so that the lower sleeve 8 and the upper sleeve 9 are tightly pressed against the outer wall of the sealing ring two 12 and the sealing ring one 3, thereby realizing the sealing connection between multiple pipes. When the connection between the pipes is affected by external impact and other reasons, causing displacement between the pipes, the sealing spring 7 will be compressed or reset, so that the lower sleeve 8 and the upper sleeve 9 can always be tightly connected to the outer wall of the sealing ring one 3 and the sealing ring two 12, maintaining the sealing performance of the pipe connection. In municipal drainage use, when the pipe is impacted and compressed by the outside world during use, the support ring 10 and the spring strip 11 will be impacted and deformed, the spring strip 11 is connected in a spiral shape to the outer wall of the inner wall pipe 1 and penetrates the inside of the support ring 10, so that the inner wall pipe 1 has better resistance when impacted, and has a longer service life.
[0028] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
