Description

Technical Field

[0001] The utility model relates to the technical field of steel-lined tetrafluoroethylene pipelines, in particular to a high-stability steel-lined tetrafluoroethylene pipeline. Background Art

[0002] Steel-lined PTFE pipes are based on ordinary carbon steel pipes and lined with thermoplastic PTFE plastic with excellent chemical stability. They are ideal pipes for transporting media such as strong acids, strong alkalis, industrial salts and highly corrosive gases. Most steel-lined PTFE pipes have I-shaped cross-sections, and some are arc-shaped for connecting two steel-lined PTFE pipes at different heights.

[0003] In the prior art, many steel-lined polytetrafluoroethylene pipes are made of slender pipes, which are easily affected by external factors, such as wind, slight vibration, etc. These factors may cause the pipe to shake or move greatly because its length-to-diameter ratio is relatively large and its ability to resist these interferences is relatively weak. Secondly, under stress, the slender pipe is more likely to bend and deform due to its own shape characteristics. Moreover, it is more difficult for the slender pipe to maintain a good support and fixed state during installation and use. Due to its long length, the middle part may be insufficiently supported, resulting in local instability. Therefore, it is necessary to design a high-stability steel-lined polytetrafluoroethylene pipe to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A high-stability steel-lined tetrafluoroethylene pipe comprises a tetrafluoroethylene pipe body 1. Two mounting rings 2 are arranged on the side wall of the tetrafluoroethylene pipe body 1. A supporting mechanism for supporting the tetrafluoroethylene pipe body 1 is arranged under the mounting ring 2. The supporting mechanism comprises a mounting cylinder 4 arranged under the mounting ring 2. A sleeve 9 is arranged in the mounting cylinder 4. A movable rod 10 is arranged in the sleeve 9. A mounting plate 5 is arranged at the lower end of the movable rod 10. A plurality of first bolts 6 are arranged at the upper end of the mounting plate 5. The first bolts 6 are expansion screws.

[0023] The mounting ring 2 is provided with a connection mechanism for connecting the tetrafluoroethylene tube body 1 , and the connection mechanism includes two second bolts 8 arranged on the mounting ring 2 , the two second bolts 8 are commonly provided with a fixing ring 3 , and the second bolts 8 are provided with nuts 7 .

[0024] In the utility model, a mounting plate 13 is fixedly connected to the side wall of the movable rod 10, two mounting strips 11 are fixedly connected to the upper end of the mounting plate 5, a plurality of third bolts 14 are arranged on the side wall of the mounting strip 11, two fixing strips 18 are fixedly connected to the lower end of the mounting ring 2, a plurality of fourth bolts 19 are arranged on the side wall of the fixing strip 18, and a fixing plate 17 is fixedly connected to the side wall of the mounting tube 4, so that the mounting ring 2 and the mounting plate 5 can be disassembled, so that when the tetrafluoroethylene tube body 1 is dismantled, the mounting plate 5 that has been installed on the ground can be disassembled, and the mounting tube 4 can also be replaced separately when it is damaged.

[0025] In the utility model, the upper end of the mounting plate 5 is fixedly connected to the first baffle 12, and the lower end of the mounting ring 2 is fixedly connected to the second baffle 20, so that when the mounting plate 13 is installed on the two mounting bars 11, there is no need for manual positioning and alignment of the threaded holes, and when the fixing plate 17 is installed on the two fixing bars 18, there is no need for manual positioning and alignment of the threaded holes.

[0026] In the utility model, the sleeve 9 is threadedly connected to the installation tube 4, and the movable rod 10 is threadedly connected to the sleeve 9, so that the sleeve 9 and the movable rod 10 will not be arbitrarily extended or retracted when stored, thereby facilitating storage.

[0027] In the utility model, two fixing tubes 15 are fixedly connected to the upper end of the fixing ring 3, and a protective sleeve 16 is threadedly connected to the fixing tube 15. A rotating block is fixedly connected to the upper end of the protective sleeve 16, which can protect the nut 7 and the first bolt 6 to avoid thread slippage.

[0028] When in use, the tetrafluoroethylene tube body 1 is connected to the corrosive pipeline system, the installation plate 5 is located on the ground, and the installation ring 2 is welded to the side wall of the tetrafluoroethylene tube body 1. The installation plate 5 can be placed on the ground by pulling out the movable rod 10 and the sleeve 9, and the joints of the installation tube 4 and the movable rod 10 are welded, and the joints of the sleeve 9 and the movable rod 10 are welded, and then the first bolt 6 is driven into the ground. When the movable rod 10 and the sleeve 9 are both about to be pulled out, the installation plate 5 still cannot contact the ground, and cement piles can be built on the ground to complete the connection with the ground. In the process, the slender tetrafluoroethylene tube body 1 can be supported, and the stability of the tetrafluoroethylene tube body 1 can be improved;

[0029] When the environment below the tetrafluoroethylene tube body 1 is relatively complex and the two mounting rings 2 cannot be installed as shown in the figure, the mounting rings 2 can be moved along the surface of the tetrafluoroethylene tube body 1 so that the supporting mechanism can adapt to different installation environments. The mounting rings 2 do not need to be welded by tightening the nuts 7.
