Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline connection structure. Background Art

[0002] The municipal water supply and drainage pipeline connection structure refers to the structure and method of connecting pipelines with different parts, different materials or different functions in the municipal water supply and drainage system to form a complete, continuous and reliable pipeline network. This connection structure is crucial for ensuring the normal operation and stability of the municipal water supply and drainage system.

[0003] Currently, the existing pipeline connection structure cannot ensure the stability of the connection between two pipelines, making it prone to loosening due to external forces or vibrations. At the same time, it cannot guarantee the sealing performance of the connection, which may cause leakage of liquid or gas from the connection. Content of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the existing technology that the stability of the connection between two pipelines cannot be ensured, and at the same time, the sealing performance of the connection cannot be guaranteed, which may cause leakage of liquid or gas from the connection, and a pipeline connection structure is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A pipeline connection structure, comprising:

[0007] Pipeline bodies, there are two pipeline bodies, and snap rings are fixedly arranged at both ends of the two pipeline bodies;

[0008] A first hoop frame, a groove is arranged in the inner circle of the first hoop frame, and through holes are arranged on both sides of the first hoop frame;

[0009] A second hoop frame, a groove is arranged in the inner circle of the second hoop frame, threaded rods are fixedly arranged on both sides of the second hoop frame, and a sealing ring is arranged between the second hoop frame and the first hoop frame;

[0010] An auxiliary component, which is arranged in the grooves of the first hoop frame and the second hoop frame and is used to tighten and seal the sealing ring.

[0011] In a possible design, the auxiliary component includes a plurality of fixed shafts fixedly arranged on both sides of the inner wall of the grooves of the first hoop frame and the second hoop frame. Two tightening frames are arranged in a mirror symmetry in the grooves of the first hoop frame and the second hoop frame. The two tightening frames in the grooves of the first hoop frame and the second hoop frame are respectively slidably connected to the fixed shafts inside them. Springs are sleeved on the outside of the plurality of fixed shafts on the side where the two tightening frames are close to each other, and both ends of the springs are fixedly connected to the two tightening frames.

[0012] In a possible design, protrusions are provided on both sides of the sealing ring, and a sealing gasket is fixedly provided in the middle section of the inner ring of the sealing ring. The sealing gasket divides the sealing ring into two placement parts.

[0013] In a possible design, the positions of the two through holes on the first hoop frame correspond to and are adapted to the positions of the two threaded rods on the second hoop frame. The diameter of the threaded rods is slightly smaller than that of the through holes. Nuts are threadedly connected to the outside of both threaded rods, and gaskets are rotatably provided on one side of both nuts.

[0014] In a possible design, the sealing ring is sleeved at the joint of two pipe bodies, and the snap rings of the two pipe bodies are respectively placed in the two placement parts of the sealing ring.

[0015] In a possible design, the first hoop frame and the second hoop frame are symmetrically sleeved outside the sealing ring in a mirror image.

[0016] In this application, when starting to use, check the two pipe bodies and the snap rings thereon to ensure that the end faces of the two pipe bodies and the snap rings thereon are flat, without impurities and damage. Prepare all necessary components, including the first hoop frame, the second hoop frame, nuts, sealing rings, etc.

[0017] Fit the two pipe bodies together so that the snap rings are also fitted together. Then, sleeve the sealing ring at the joint of the two pipe bodies, ensuring that the snap rings of the two pipe bodies are respectively placed in the two placement parts of the sealing ring, separated by the sealing gasket. Then install the first hoop frame, align the groove of the first hoop frame with the pipe joint, ensuring that the sealing ring is located between the two tightening frames in the groove of the first hoop frame. Subsequently, install the second hoop frame, align the groove of the second hoop frame with the first hoop frame and sleeve it outside the sealing ring, and make the threaded rods of the second hoop frame pass through the through holes of the first hoop frame, while ensuring that the sealing ring is located between the two tightening frames in the groove of the second hoop frame. Subsequently, install the nuts, screw the two nuts onto the two threaded rods respectively, and gradually tighten the nuts to make the first hoop frame and the second hoop frame move towards each other. By the nuts pushing the first hoop frame and the second hoop frame towards each other, the two tightening frames slide on the fixed shaft to apply pressure to the outside of the sealing ring, causing the sealing ring to tighten inward against the two snap rings, thereby making the joint of the two pipe bodies more stable. At the same time, the sealing ring tightly abuts and wraps the snap rings of the two pipe bodies, increasing the sealing performance between them. When rotating the nuts, the gasket at the bottom of the nuts increases the friction between the nuts and the first hoop frame, preventing loosening.

[0018] After installation, check whether the sealing ring is evenly tightened, without local over-tightening or over-loosening. Regularly check whether there is any leakage at the joint. If there is leakage, adjust the tightness of the nuts in time and check whether the sealing ring is aging to ensure the sealing performance.

[0019] The utility model has the following beneficial effects:

[0020] In the utility model, through the arrangement of the auxiliary component, when the nut is tightened, the first hoop frame and the second hoop frame will move towards each other, so that the two tightening frames slide on the fixed shaft, applying uniform pressure to the outer side of the sealing ring. Thus, the sealing ring is tightened inward, tightly pressing against the snap rings of the two pipe bodies, thereby ensuring that the two pipe bodies are more stable at the connection and not easily loosened due to external force or vibration. After the sealing ring is subjected to the pressure of the tightening frame, it will tightly press against and wrap the snap rings of the two pipe bodies, effectively preventing liquid or gas from leaking from the connection and ensuring the sealing performance of the pipeline system;

[0021] In the utility model, through the arrangement of the first hoop frame, the second hoop frame, the threaded rod and the nut, the installer only needs to place the first hoop frame and the second hoop frame at the connection of the pipeline and drive the threaded rod by rotating the nut, thereby pushing the two hoop frames to move towards each other. The whole process does not require complex tools or special skills, greatly shortening the installation time. Due to the existence of the threaded rod and the nut, the installer can adjust the tightening force according to actual needs. By rotating the nut, the distance between the first hoop frame and the second hoop frame can be accurately controlled, so as to ensure that the sealing ring can tightly press against the snap ring of the pipeline and achieve a good sealing effect;

[0022] Through the arrangement of the auxiliary component, the utility model ensures the stability of the connection of the two pipe bodies, making it not easily loosened due to external force or vibration, and at the same time effectively preventing liquid or gas from leaking from the connection and ensuring the sealing performance of the pipeline system.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Embodiment 1

[0030] Referring to Figures 1-4 , a pipeline connection structure is used in the technical field of municipal water supply and drainage pipeline connection structures, and includes:

[0031] Pipeline body 1, there are two pipeline bodies 1, and snap rings 101 are fixedly arranged at both ends of the two pipeline bodies 1 for positioning and fixing subsequent connection components.

[0032] A groove is provided in the inner circle of the first hoop 2, and through holes are provided on both sides of the first hoop 2 for cooperating with the threaded rods 4 on the second hoop 3.

[0033] A groove is also provided in the inner circle of the second hoop 3 and corresponds to the groove of the first hoop 2. Threaded rods 4 are fixedly arranged on both sides of the second hoop 3 for cooperating with the through holes on the first hoop 2 and being fixed by nuts 5. A sealing ring 6 is arranged between the second hoop 3 and the first hoop 2 to ensure the sealing performance of the connection.

[0034] The auxiliary component is arranged in the grooves of the first hoop 2 and the second hoop 3 for tightening the sealing ring 6. The auxiliary component includes a fixed shaft 8 and a tightening frame 7. The fixed shaft 8 is fixedly arranged on both sides of the inner wall of the grooves of the first hoop 2 and the second hoop 3, and the tightening frame 7 is slidably connected to the fixed shaft 8. A spring 9 is sleeved outside the fixed shaft 8 on the side where the two tightening frames 7 are close to each other, and both ends of the spring 9 are fixedly connected to the two tightening frames 7 to provide a tightening force. When the nut 5 is tightened, the first hoop 2 and the second hoop 3 move towards each other, causing the two tightening frames 7 to slide on the fixed shaft 8, applying a uniform pressure to the outer side of the sealing ring 6. Thus, the sealing ring 6 is tightened inward and tightly abuts against the snap rings 101 of the two pipeline bodies 1, thereby ensuring that the two pipeline bodies 1 are more stable at the connection and are not easily loosened due to external force or vibration. After the sealing ring 6 is subjected to the pressure of the tightening frame 7, it tightly abuts against and wraps the snap rings 101 of the two pipeline bodies 1, effectively preventing liquid or gas from leaking from the connection and ensuring the sealing performance of the pipeline system.

[0035] On both sides of the sealing ring 6, there are protrusions 601, which are convenient for being tightened by the tightening frame 7. At the same time, it is also convenient for the sealing between the sealing ring 6 and the first hoop frame 2 and the second hoop frame 3, preventing external corrosive substances from entering and corroding the sealing ring 6. A sealing gasket 602 is fixedly arranged in the middle of the inner ring of the sealing ring 6. The sealing gasket 602 divides the sealing ring 6 into two placement parts, corresponding to the snap rings 101 of the two pipe bodies 1 respectively, ensuring that each snap ring 101 can be fully sealed.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
