Description

Technical Field

[0001] This utility model relates to the field of PVC-C liner technology, and in particular to a PVC-C liner with an embedded marking line. Background Technology

[0002] PVC-C piping systems offer high mechanical strength at high temperatures, making them suitable for pressurized applications. They can operate at temperatures up to approximately 90 degrees Celsius, have a lifespan of up to 50 years, and are safe and easy to use.

[0003] Existing PVC-C liners are typically installed using flux bonding or flange connections. Solvent bonding results in unreliable adhesion, while flange connections complicate the installation process. Therefore, we are introducing a new type of PVC-C liner with embedded marking lines. Utility Model Content

[0004] The main purpose of this utility model is to provide a PVC-C liner with an embedded marking line, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PVC-C liner with embedded marking lines includes a first pipe body and a second pipe body. The right end of the first pipe body is fixedly connected to a first connecting plate, and the left end of the second pipe body is fixedly connected to a second connecting plate. The first and second connecting plates each have four through slots on their opposite surfaces. A connecting mechanism is inserted between two transverse through slots. The outer surface of the second connecting plate has four limiting slots. A sealing ring is provided between the first and second connecting plates. The inner walls of both the first and second pipe bodies have built-in marking lines, and the outer walls of both the first and second pipe bodies have external marking lines.

[0007] Preferably, the connecting mechanism includes a through strip, a limiting piece is fixedly connected to the left end of the through strip, a pull ring is fixedly connected to the left end of the limiting piece, a movable groove is opened in the right part of the through strip, a spring is fixedly connected to the lower wall of the movable groove, a connecting block is fixedly connected to the upper end of the spring, and a limiting block is fixedly connected to the upper end of the connecting block.

[0008] Preferably, the threading strip is interlocked with the two transverse threading slots, and the right end of the limiting piece is tightly fitted with the first connecting plate.

[0009] By adopting the above technical solution, the right end of the limiting piece is tightly fitted with the No. 1 connecting plate, which can improve the tightness of the connection.

[0010] Preferably, the connecting block is located inside the movable groove, and the limiting block is interlocked with the corresponding limiting groove.

[0011] By adopting the above technical solution, the limiting block pops out of the limiting groove under the elastic force of the spring, making it easy for the first tube to be connected to the second tube.

[0012] Preferably, the four through slots on the left side correspond to the positions of the four through slots on the right side.

[0013] By adopting the above technical solution, the threading strip can be inserted into two transverse grooves.

[0014] Preferably, the four limiting grooves are respectively connected to the interior of the four through grooves on the right side.

[0015] By adopting the above technical solution, the limiting block can smoothly pass through the limiting groove when it is inserted into the groove.

[0016] Preferably, the four built-in marker lines correspond to the positions of the four external marker lines.

[0017] By adopting the above technical solution, the built-in marking lines can help construction personnel determine the location and direction of pipelines, ensuring the accuracy and consistency of pipeline installation. They can also serve as reference marks for pipeline inspection and maintenance. For example, when performing endoscopic inspection or repair of pipelines, the marking lines can help inspectors quickly locate specific positions of pipelines, improving work efficiency.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. By connecting pipe body 1 and pipe body 2, and pressing the limiting block to retract it into the movable groove, and squeezing the spring through the connecting block, the through strip passes through the through groove on the connecting plate 1 and exits through the through groove on the connecting plate 2. The limiting block pops out from the corresponding limiting groove under the spring force. At the same time, the right side of the limiting piece fits tightly with the left side of the connecting plate 1. The other three connecting mechanisms are connected and installed in the same way, making it easy to connect and install pipe body 1 and pipe body 2. This simplifies the installation process, reduces construction time and manpower input, and allows the project to be completed faster, saving time and costs. It also eliminates the need for complex technology and professional tools, reduces the skill level requirements of construction personnel, and reduces technical difficulties and operational errors during construction.

[0020] 2. By installing a sealing ring between the No. 1 and No. 2 connecting plates, the sealing performance between the No. 1 and No. 2 pipe bodies can be improved. Built-in marking lines are installed inside both the No. 1 and No. 2 pipe bodies, while external marking lines are installed outside both the No. 1 and No. 2 pipe bodies. The built-in marking lines help construction personnel determine the location and direction of the pipeline, ensuring the accuracy and consistency of pipeline installation. They also serve as reference marks for pipeline inspection and maintenance. For example, during endoscopic inspection or repair of the pipeline, the marking lines help inspectors quickly locate specific positions on the pipeline, improving work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A PVC-C liner with embedded marking lines includes a first pipe body 1 and a second pipe body 2. The right end of the first pipe body 1 is fixedly connected to a first connecting plate 3, and the left end of the second pipe body 2 is fixedly connected to a second connecting plate 4. The first connecting plate 3 and the second connecting plate 4 each have four through slots 5 on their opposite sides. A connecting mechanism 6 is inserted between two transverse through slots 5. The outer surface of the second connecting plate 4 has four limiting slots 7. A sealing ring 8 is provided between the first connecting plate 3 and the second connecting plate 4. The inner wall of the first pipe body 1 and the inner wall of the second pipe body 2 are provided with built-in marking lines 9. The outer wall of the first pipe body 1 and the outer wall of the second pipe body 2 are provided with external marking lines 10.

[0031] In this embodiment, the connecting mechanism 6 includes a through strip 61, a limiting piece 62 is fixedly connected to the left end of the through strip 61, a pull ring 63 is fixedly connected to the left end of the limiting piece 62, a movable groove 64 is provided in the right part of the through strip 61, a spring 65 is fixedly connected to the lower wall of the movable groove 64, a connecting block 66 is fixedly connected to the upper end of the spring 65, a limiting block 67 is fixedly connected to the upper end of the connecting block 66, the through strip 61 and the two transverse through grooves 5 are interlocked, the right end of the limiting piece 62 is tightly fitted to the first connecting plate 3, the connecting block 66 is located inside the movable groove 64, and the limiting block 67 is interlocked with the corresponding limiting groove 7.

[0032] The above solution involves connecting pipe body 1 and pipe body 2, pressing the limiting block 67 to retract it into the movable groove 64, and then squeezing the spring 65 through the connecting block 66. The threaded strip 61 passes through the groove 5 on the connecting plate 3 and exits through the groove 5 on the connecting plate 4. The limiting block 67 pops out from the corresponding limiting groove 7 under the elastic force of the spring 65. Simultaneously, the right side of the limiting piece 62 fits tightly against the left side of the connecting plate 3. The other three connecting mechanisms 6 are then connected and installed in the same manner. This facilitates the connection and installation of pipe body 1 and pipe body 2, simplifies the installation process, reduces construction time and manpower input, allows the project to be completed faster, saves time costs, and eliminates the need for complex techniques and specialized tools, thus reducing the skill requirements for construction personnel and minimizing technical difficulties and operational errors during construction.

[0033] In this embodiment, the four through slots 5 on the left side correspond to the four through slots 5 on the right side, the four limiting slots 7 are connected to the inside of the four through slots 5 on the right side, and the four built-in marking lines 9 correspond to the positions of the four external marking lines 10.

[0034] The above solution allows construction workers to determine the location and direction of pipelines through built-in marking lines 9, ensuring the accuracy and consistency of pipeline installation. It can also serve as a reference mark for pipeline inspection and maintenance. For example, during pipeline endoscopic inspection or repair, the marking lines can help inspectors quickly locate specific positions on the pipeline, improving work efficiency.

[0035] It should be noted that this utility model is a PVC-C liner with an embedded marking line. During use, when connecting the first pipe body 1 and the second pipe body 2, the limiting block 67 is manually pressed, causing it to move inward along the movable groove 64. This action applies pressure to the built-in spring 65 via the connecting block 66, compressing it. Subsequently, the threading strip 61 smoothly passes through the through groove 5 on the first connecting plate 3 and continues to pass through the other through groove 5 on the second connecting plate 4. At this time, the pressure on the limiting block 67 is released, and the spring 65 automatically resets due to its elasticity, pushing the limiting block 67 to pop out into the corresponding limiting groove 7 and lock in place. At the same time, it ensures that the right side of the limiting piece 62 is tightly fitted with the left side of the first connecting plate 3, forming a stable connection. This process is repeated for the other three connecting mechanisms 6, thereby efficiently completing the connection of the first pipe body. The overall docking installation of pipe body 1 and pipe body 2 not only simplifies the installation steps, significantly shortens the construction cycle and reduces labor costs, and accelerates the progress of the project, but also reduces the reliance on the professional skills of construction personnel, reduces technical obstacles and errors in operation, and improves the overall construction efficiency. In addition, a sealing ring 8 is added between connecting plate 1 3 and connecting plate 2 4 to enhance the sealing of the connection between the pipe bodies. At the same time, internal marking lines 9 and external marking lines 10 are arranged inside and outside the pipe body, respectively. The internal marking line 9 not only provides construction personnel with clear guidance on the location and direction of the pipeline, ensuring accurate installation, but also serves as an important reference point for subsequent pipeline inspection and maintenance. For example, when inspecting or repairing the inside of the pipeline, the marking line can quickly guide the staff to locate the specific pipe section, greatly improving work efficiency and accuracy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
