Description

Technical Field

[0001] This utility model relates to the field of PTFE-lined steel pipe technology, specifically a PTFE-lined steel pipe with anti-deformation connection. Background Technology

[0002] PTFE-lined steel pipes are a type of composite pipe structure, characterized by an outer metal support layer and an inner PTFE corrosion protection layer. They are specifically designed to solve the problem of transporting corrosive media. Specifically, they use a metal pipe (usually carbon steel or stainless steel) as the outer structure, providing mechanical strength, pressure resistance, and overall support; the inner layer is lined with polytetrafluoroethylene (PTFE, commonly known as "tetrafluoroethylene") material. Utilizing PTFE's excellent chemical inertness, resistance to high and low temperatures, and non-stick properties, it achieves isolation and protection against highly corrosive media.

[0003] Existing PTFE-lined steel pipes are mostly straight cylinders during operation. The straight cylinder design can cause the liquid to flow too fast, which can impact the pipe and cause it to deform. This can affect the use of equipment and fail to meet user needs. To address these issues, we propose to innovate the technology based on existing PTFE-lined steel pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a steel-lined PTFE pipe with anti-deformation connection to solve the problem mentioned in the background art that the pipe cannot adequately meet people's usage needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel-lined PTFE pipe with anti-deformation connection, comprising a pipe assembly, wherein an impact-resistant component is provided inside the pipe assembly, and a rotating cleaning component is installed inside the impact-resistant component. The rotating cleaning component includes a central rotating shaft, a worm gear, a cleaning scraper, and a fixing rod. The worm gear is installed in the middle of the central rotating shaft, the cleaning scraper is installed at both the front and rear ends of the central rotating shaft, and the fixing rod is installed at both the upper and lower ends of the central rotating shaft.

[0006] Furthermore, a fastening component is installed at the end of the pipe assembly, and an auxiliary fastening component is provided on the outside of the fastening component, with a rubber ring embedded on the auxiliary fastening component.

[0007] Furthermore, the pipe assembly includes an outer steel pipe, a first connecting ring, and a second connecting ring, with the upper end of the outer steel pipe connected to the first connecting ring and the lower end of the outer steel pipe connected to the second connecting ring.

[0008] Furthermore, the fastening assembly includes a bolt shank and a bolt head, with the bolt head connected to the end of the bolt shank.

[0009] Furthermore, the auxiliary fastening assembly includes a compression block, an inner cavity, a locking block, and a compression bolt. The compression block has an inner cavity, and the locking block is installed inside the inner cavity. The side of the locking block away from the center of the compression block is connected to the compression bolt.

[0010] Furthermore, the impact-resistant component includes an inner bushing and an impact-resistant ring, with the impact-resistant ring embedded inside the inner bushing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The device has the effect of rotating by the force of liquid flow, cleaning the inside of the device by rotating, while also obstructing the flow of liquid, reducing the flow rate, and protecting the device. The device has an auxiliary sealing structure, which can increase the sealing between devices and prevent leakage.

[0012] 1. During operation, this utility model uses a worm gear to obstruct the flow of liquid, thereby reducing the liquid flow rate. This reduces the impact force of the liquid to a certain extent. At the same time, the rotation of the worm gear drives the cleaning scraper to rotate, which in turn drives the liquid to flow in a spiral manner, thus reducing the damage from direct impact and the possibility of equipment deformation.

[0013] 2. This utility model uses the fastening components to squeeze the first connecting ring and the second connecting ring, so that the auxiliary fastening components are squeezed inward as much as possible until they are completely assembled into a ring, so that the auxiliary fastening components cooperate with the rubber ring and increase the sealing effect of the equipment.

[0018] like Figure 1 and Figure 3 As shown, a steel-lined PTFE pipe with anti-deformation connection includes a pipe assembly 1. An impact-resistant component 5 is provided inside the pipe assembly 1, and a rotating cleaning component 6 is installed inside the impact-resistant component 5. The rotating cleaning component 6 includes a central rotating shaft 601, a worm gear 602, a cleaning scraper 603, and a fixing rod 604. The worm gear 602 is installed in the middle of the central rotating shaft 601, the cleaning scraper 603 is installed at both the front and rear ends of the central rotating shaft 601, and the fixing rod 604 is installed at both the upper and lower ends of the central rotating shaft 601.

[0019] The connection between the central rotating shaft 601 and the fixed rod 604 is a rotating connection. The fixed rod 604 only serves to limit the movement of the central rotating shaft 601, preventing it from moving randomly. However, the central rotating shaft 601 can rotate. When the liquid inside the equipment flows, it will drive the worm gear 602 to rotate, thereby driving the central rotating shaft 601 to rotate. This causes the cleaning scraper 603 to rotate as well, cleaning the surface of the inner liner 501.

[0020] During operation, the worm gear 602 obstructs the liquid flow, thereby reducing the liquid velocity and reducing the impact force of the liquid to a certain extent. At the same time, the rotation of the worm gear 602 drives the cleaning scraper 603 to rotate, which in turn drives the liquid to flow in a spiral manner, thus reducing the damage from direct impact and minimizing the possibility of equipment deformation.

[0021] like Figure 1 and Figure 2 As shown, a fastening component 2 is installed at the end of the pipe assembly 1, and an auxiliary fastening component 4 is provided on the outside of the fastening component 2, with a rubber ring 3 embedded on the auxiliary fastening component 4.

[0022] like Figure 1 As shown, the pipe assembly 1 includes an outer steel pipe 101, a first connecting ring 102 and a second connecting ring 103, with the upper end of the outer steel pipe 101 connected to the first connecting ring 102 and the lower end of the outer steel pipe 101 connected to the second connecting ring 103.

[0023] The outer steel pipe 101 is fixedly connected to the first connecting ring 102 and the second connecting ring 103. The structures of the first connecting ring 102 and the second connecting ring 103 are completely identical.

[0024] like Figure 1 As shown, the fastening assembly 2 includes a bolt rod 201 and a bolt head 202, and the bolt head 202 is connected to the end of the bolt rod 201;

[0025] The bolt rod 201 and the bolt head 202 are threaded together. The first connecting ring 102 and the second connecting ring 103 are connected through the threaded connection between the bolt rod 201 and the bolt head 202, so that multiple devices are connected into a whole.

[0026] like Figure 2 As shown, the auxiliary fastening assembly 4 includes a pressing block 401, an inner cavity 402, a locking block 403, and a pressing bolt 404. The pressing block 401 has an inner cavity 402 inside, and the locking block 403 is installed inside the inner cavity 402. The pressing bolt 404 is connected to the side of the locking block 403 away from the center of the pressing block 401.

[0027] The pressing bolt 404 and the pressing block 401 are threaded together. The rotation of the pressing bolt 404 pushes the locking block 403. The pressing bolt 404 and the locking block 403 are rotatably connected. When the pressing bolt 404 pushes the locking block 403, it can make the locking block 403 and the bolt rod 201 in close contact, blocking the rotation of the bolt rod 201 and preventing the bolt rod 201 from rotating, thereby ensuring the stability of the bolt rod 201. The locking block 403 is made of rubber, which has the same effect as the rubber ring on the self-locking bolt.

[0028] By pressing the first connecting ring 102 and the second connecting ring 103 with the fastening component 2, the auxiliary fastening component 4 is pressed inward as much as possible until it is completely assembled into a ring, so that the auxiliary fastening component 4 cooperates with the rubber ring 3 to increase the sealing effect of the equipment.

[0029] like Figure 3 As shown, the impact-resistant component 5 includes an inner bushing 501 and an impact-resistant ring 502, and the impact-resistant ring 502 is embedded inside the inner bushing 501.

[0030] The inner liner 501 is inlaid with an anti-impact ring 502. The arc-shaped structure of the anti-impact ring 502 changes the impact direction of the liquid when it is impacted, reducing the damage of the liquid to the equipment.

[0031] Working principle: When using this anti-deformation connection for steel-lined PTFE pipes, first pre-place the three rubber rings 3 in the designated positions, such as... Figure 1As shown, multiple auxiliary fastening components 4 are then arranged on the first connecting ring 102, and the bolt rod 201 is passed through the inner cavity 402. Multiple devices are connected together through the first connecting ring 102 and the second connecting ring 103, and then fixed by the fastening components 2. In this way, the squeezing force of the fastening components 2 can make multiple auxiliary fastening components 4 splice together to perform auxiliary sealing. The locking block 403 can squeeze the bolt rod 201 to achieve the effect of auxiliary locking. After the equipment is installed, liquid is introduced into the equipment for operation. The impact-resistant ring 502 can change the direction of the liquid when it is impacted, so that the liquid flows inward. This can reduce the impact of the liquid on the inner bushing 501, protect the equipment from deformation, and at the same time, the liquid will also drive the worm gear 602 to rotate, which will drive the central rotating shaft 601 to rotate, so that the cleaning scraper 603 cleans the inner bushing 501, which facilitates the continuous operation of the equipment.
