Description

Technical Field

[0001] The utility model relates to the technical field of thick-walled corrugated pipes, in particular to a thick-walled corrugated pipe with a sealing structure. Background Art

[0002] Thick-walled corrugated pipe is a pressure pipe used to transport fluid media under high temperature and high pressure environments. It has the characteristics of high strength, corrosion resistance and high temperature resistance. Due to its excellent performance, thick-walled corrugated pipe has gradually replaced traditional steel pipes and cast iron pipes and is widely used in various industrial fields.

[0003] Since the length of a single corrugated pipe is often limited, for some situations where long-distance medium transmission is required, long-distance transmission must be achieved by connecting multiple corrugated pipes. Multiple corrugated pipes are generally connected by welding. When the corrugated pipe is installed in a humid area, the moisture in the air will condense at the welding part and react chemically with the metal, causing rust and corrosion, which will affect the structural strength of the connection part of the corrugated pipe and cause leakage at the connection part. For this reason, we propose a thick-walled corrugated pipe with a sealing structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a thick-walled corrugated pipe with a sealing structure.

[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 the embodiments.

[0022] Reference Figure 1-4 A thick-walled corrugated pipe with a sealing structure includes a thick-walled corrugated pipe body 1. There are two groups of thick-walled corrugated pipe bodies 1, and the two groups of thick-walled corrugated pipe bodies 1 are connected to a connecting pipe 2 on the side close to each other. The outer sides of the connecting pipes 2 are respectively sleeved with connecting rings 3, and the inner side of one group of connecting rings 3 is connected to a first protective sleeve 4, and the inner side of the other group of connecting rings 3 is connected to a second protective sleeve 5. The side of the first protective sleeve 4 is provided with an annular groove adapted to the second protective sleeve 5. By setting the first protective sleeve 4, the second protective sleeve 5 and the annular groove, the protection operation of the welding part of the connecting pipe 2 can be realized. Since the connecting ring 3 is movably sleeved on the outer side of the connecting pipe 2, the requirement of the first protective sleeve 4 and the second protective sleeve 5 being away from each other can be met, which can facilitate the staff to weld the connecting part of the connecting pipe 2.

[0023] Further, refer to Figure 3 It can be seen that the sides of the connecting rings 3 that are away from each other are respectively connected to the fixing rings 6, and a threaded rod 7 is inserted inside the fixing ring 6. The inner side of the threaded rod 7 is connected to the arc plate 8 through a bearing. During use, the connecting ring 3 moved to the appropriate position can be limited and fixed by the mutual cooperation of the threaded rod 7 and the arc plate 8.

[0024] Further, refer to Figure 2 It can be seen that a guide rod 10 is connected to the side of the arc plate 8 away from the connecting pipe 2, and a connecting groove adapted to the guide rod 10 is opened inside the fixing ring 6. When in use, the guiding operation of the arc plate 8 can be realized through the setting of the fixing ring 6.

[0025] Further, refer to Figure 3 It can be seen that a sealing ring 12 is connected to the inner side of the connecting ring 3, and the inner wall of the sealing ring 12 is tightly fitted to the outer wall of the connecting pipe 2. When in use, the setting of the sealing ring 12 can effectively ensure the tightness of the connecting ring 3 on the outside of the connecting pipe 2.

[0026] Further, refer to Figure 3 It can be seen that a rubber plate 9 is glued to the side of the arc plate 8 away from the threaded rod 7, and anti-slip particles are evenly distributed on the outer surface of the rubber plate 9. When in use, the limiting effect of the connecting ring 3 can be further improved through the mutual cooperation between the rubber plate 9 and the anti-slip particles.

[0027] Further, refer to Figure 1 and Figure 2It can be seen that the inner side of one group of fixing rings 6 is connected to a sleeve rod 13, and the inner side of the other group of fixing rings 6 is connected to an insertion rod 14. When in use, the connection strength between the connecting pipes 2 can be guaranteed by the mutual cooperation of the sleeve rod 13 and the insertion rod 14, thereby realizing the reinforcement operation between the two groups of fixing rings 6, so as to effectively prevent the first protective sleeve 4 and the second protective sleeve 5 from being easily deformed and damaged by force during the sleeve process.

[0028] Further, refer to Figure 3 It can be seen that the end of the threaded rod 7 is connected to a rotating block 11, and the outer wall of the rotating block 11 is evenly connected with raised balls. Through the mutual cooperation between the rotating block 11 and the raised balls, the staff can quickly rotate the threaded rod 7, thereby effectively improving the convenience of using the device.

[0029] Working principle: When using the present invention, the staff can first place the two groups of thick-walled corrugated pipe bodies 1 that need to be connected side by side, so that the connecting pipes 2 connected to the sides of the thick-walled corrugated pipe bodies 1 are close to each other, and then the staff can respectively sleeve the two groups of connecting rings 3 on the outside of the two groups of connecting pipes 2. After the sleeves are completed, the staff can fit the connecting pipes 2 connected to the ends of the thick-walled corrugated pipe bodies 1 together, and use the corresponding workpieces to weld the connecting pipes 2 together. After the welding is completed, the staff can push the two groups of connecting rings 3 to make the first protective sleeve 4 and the second protective sleeve 5 close to each other, so that The second protective sleeve 5 is inserted into the interior of the first protective sleeve 4, and each group of insertion rods 14 is inserted into the sleeve rod 13, and then the staff can rotate the rotating block 11 in sequence, thereby driving the threaded rod 7 and the fixing ring 6 to engage with each other, so that the rubber plate 9 connected to the inner side of the arc plate 8 is forced to abut against the outer wall of the connecting pipe 2. By bringing the two groups of rubber plates 9 closer to each other, the positioning operation of the connecting ring 3 can be achieved, and the first protective sleeve 4 and the second protective sleeve 5 connected to the inner side of the connecting ring 3 can achieve the protective sealing operation of the welding part. The above is the entire working principle of the present utility model.
