Description

Technical Field

[0001] This utility model relates to the field of pipeline protection technology, and in particular to a gas pipeline connection mechanism with anti-corrosion function. Background Technology

[0002] Pressure regulating boxes are crucial equipment in urban gas transmission and distribution systems. Their function is to regulate gas pressure within the transmission and distribution network, ensuring the stability and safety of gas supply to end users. However, due to the high humidity and salinity in southern regions, the corrosive environment is relatively harsh, leading to severe water accumulation and corrosion at the connections between pipes and fittings.

[0003] Currently, the method for preventing corrosion of gas pipelines is to apply anti-rust paint. However, in areas with harsh corrosive environments, the anti-rust effect of the paint is greatly reduced. Utility Model Content

[0004] In order to solve the technical problem of severe corrosion at the connection between pipes and connectors in the prior art, this utility model provides a gas pipeline connection mechanism with anti-corrosion function.

[0005] The gas pipeline connection mechanism with anti-corrosion function provided by this utility model adopts the following technical solution: A gas pipeline connection mechanism with anti-corrosion function includes a connecting part and nut assemblies disposed at both ends of the connecting part. Pipe 1 and pipe 2 are respectively fixedly installed on both sides of the connecting part by the nut assemblies. The nut assemblies are fixed to both ends of the connecting part by screwing in the threads, and clamp and fix pipe 1 and pipe 2 to both ends of the connecting part. A protective component is provided on the nut assembly to cover and protect the connection position of pipe 1 and pipe 2 with the end of the nut assembly. The protective component includes an arc-shaped plate that slides inside the nut assembly and a sealing sleeve that is sleeved on the end of the arc-shaped plate.

[0006] By adopting the above technical solution, corrosion can be prevented at the connection points between pipe one and pipe two and the nut assembly ends. Furthermore, the docking component includes a fixed platform located at the center, with both ends of the fixed platform extending outward to form threaded connecting platforms. The fixed platform has mounting holes inside, which pass through the threaded connecting platforms on both sides of the fixed platform.

[0007] By adopting the above technical solution, installation space is provided for pipe one and pipe two.

[0008] Furthermore, sealing rings are connected to the inner walls on both sides of the mounting hole, and grooves are opened on both sides of the mounting hole near the ends, with the sealing rings embedded in the grooves.

[0009] By adopting the above technical solution, when pipe one and pipe two are inserted into the threaded connector, the sealing ring is clamped between the outer wall of pipe one and pipe two and the side wall of the threaded connector, thus achieving a sealing effect on the connection position of pipe one and pipe two.

[0010] Furthermore, the nut assembly includes a nut and a clamping member disposed on the inner end of the nut. A locking groove is formed between the clamping member and the internal thread of the nut. A tapered surface is formed at the end of the clamping member, and multiple clamping grooves are provided on the tapered surface. An inclined surface corresponding to the tapered surface is located inside the threaded joint.

[0011] By adopting the above technical solution: during docking, pipe one or pipe two is inserted into the docking part through the nut assembly, and the nut is rotated to tighten it onto the threaded connecting platform. During the tightening process, the threaded connecting platform is locked in the locking groove between the clamping member and the nut, and the inclined surface inside the threaded connecting platform applies pressure to the conical surface in the clamping member so that the clamping member clamps and fixes the installation position of pipe one or pipe two.

[0012] Furthermore, there are two arc-shaped plates, with two through arc-shaped holes symmetrically opened inside the side wall of the nut. The two arc-shaped plates are symmetrically arranged in the two arc-shaped holes, and the ends of the arc-shaped plates slide outward along the arc-shaped holes. A connecting platform is formed by protruding outward at the end of the nut. One end of the sealing sleeve is fitted onto the arc-shaped hole, and the other end of the sealing sleeve is fitted onto the end of the arc-shaped plate.

[0013] By adopting the above technical solution: fixing pipe one or pipe two inside the nut assembly, pulling the arc plate outward, so that the end of the arc plate moves out of the sealing sleeve, so that one end of the sealing sleeve is fitted onto the connecting platform, and the other end is fitted onto the outer wall of pipe one or pipe two under its own elastic force, thereby sealing and protecting the connection position between pipe one or pipe two and the end of the nut assembly.

[0014] Furthermore, the sealing sleeve is made of fluororubber or perfluoroether rubber.

[0015] By adopting the above technical solutions, fluororubber and perfluoroether rubber combine excellent elasticity, strong oxidation resistance and corrosion resistance, making them the first choice for rust-proof protection structures.

[0016] Furthermore, the end of the clamping member also has a support wall, which is sleeved on the outside of pipe one or pipe two.

[0017] By adopting the above technical solution, the gap between the nut assembly and the outer wall of pipe one or pipe two is reduced, and the support wall provides outward support to the side wall of the sealing sleeve when the sealing sleeve is sealing.

[0018] Furthermore, a set screw is screwed onto the end of the arc-shaped plate away from the sealing sleeve.

[0019] By adopting the above technical solution, the locking screw is pressed tightly against the outer wall of the threaded connector, preventing the nut from loosening during use.

[0020] In summary, the beneficial effects of this utility model are as follows: This utility model incorporates a protective component with a set screw. During use, pipes one and two are inserted into the connecting piece via a nut assembly. The nut is then turned to lock it onto the threaded connecting platform. During tightening, a clamping component holds and secures the installation positions of pipes one and two. After fixing pipes one and two within the nut assembly, the arc-shaped plate is pulled outwards, causing its end to move out of the sealing sleeve. This allows one end of the sealing sleeve to engage with the connecting platform, while the other end, under its own elasticity, engages with the outer wall of pipe one or two. This seals and protects the connection between pipes one and two and the end of the nut assembly, preventing corrosion. Finally, the set screw is tightened to press the nut firmly against the outer wall of the threaded connecting platform, preventing loosening during use. This gas pipeline connection mechanism not only has anti-corrosion and anti-loosening functions, offering high practical value and improving the connection effect of gas pipelines.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0024] The first embodiment of this utility model, referred to... Figure 1 As shown, a gas pipeline connection mechanism with anti-corrosion function is disclosed, including a connecting member 2 and nut assemblies 3 disposed at both ends of the connecting member 2. Pipeline 11 and pipeline 22 are respectively fixedly installed on both sides of the connecting member 2 by the nut assemblies 3, so that pipeline 11 and pipeline 22 can be securely connected. The nut assemblies 3 are fixed to both ends of the connecting member 2 by threading, clamping and fixing pipeline 11 and pipeline 22 to both ends of the connecting member 2. To prevent corrosion at the connection points between pipeline 11 and pipeline 22 and the ends of the nut assemblies 3, protective components 4 are provided on the nut assemblies 3 to cover and protect the connection points between pipeline 11 and pipeline 22 and the ends of the nut assemblies 3.

[0025] Among them, reference Figure 2 and Figure 3 As shown, the connecting member 2 includes a fixed platform 21 located at the center. The two ends of the fixed platform 21 extend outwards to form threaded connecting platforms 22. The fixed platform 21 has mounting holes 23 inside, which penetrate the threaded connecting platforms 22 on both sides of the fixed platform 21, providing installation space for pipe 11 and pipe 22. Sealing rings 6 are connected to the inner walls on both sides of the mounting holes 23. Preferably, grooves are formed near the ends on both sides of the mounting holes 23, and the sealing rings 6 are embedded in these grooves. When pipe 11 and pipe 22 are inserted into the threaded connecting platforms 22, the sealing rings 6 are clamped between the outer walls of pipe 11 and pipe 22 and the side walls of the threaded connecting platforms 22, providing a sealing effect at the connection point of pipe 11 and pipe 22 and improving the sealing performance of the connecting parts.

[0026] Specifically, refer to Figure 3 and Figure 4As shown, the nut assembly 3 includes a nut 31 and a clamping member 32 disposed on the inner end of the nut 31. Preferably, a locking groove is formed between the clamping member 32 and the internal threads of the nut 31, and a tapered surface 321 is formed at the end of the clamping member 32. Multiple clamping grooves 322 are provided on the tapered surface 321, and an inclined surface corresponding to the tapered surface 321 is located inside the threaded connecting platform 22. During connection, pipe 11 or pipe 2 12 is inserted into the connecting member 2 through the nut assembly 3, and the nut 31 is rotated to tighten it onto the threaded connecting platform 22. During the tightening process, the threaded connecting platform 22 is locked in the locking groove between the clamping member 32 and the nut 31, and the inclined surface inside the threaded connecting platform 22 applies pressure to the tapered surface 321 in the clamping member 32, so that the clamping member 32 clamps and fixes the installation position of pipe 11 or pipe 2 12.

[0027] Moreover, referencing Figure 3 and Figure 4 As shown, the protective assembly 4 includes an arc-shaped plate 41 slidingly disposed within the side wall of the clamping member 32 and a sealing sleeve 42 sleeved on the end of the arc-shaped plate 41. Preferably, there are two arc-shaped plates 41, with two through arc-shaped holes 311 symmetrically formed within the side wall of the nut 31. The two arc-shaped plates 41 are symmetrically arranged in the two arc-shaped holes 311, and the ends of the arc-shaped plates 41 slide outward along the arc-shaped holes 311. A connecting platform 312 protrudes outward from the end of the nut 31, and one end of the sealing sleeve 42 is sleeved on the arc-shaped hole 311, while the other end of the sealing sleeve 42 is sleeved on the end of the arc-shaped plate 41. (Refer to...) Figures 5-7 As shown, pipe 11 or pipe 2 12 is fixed inside the nut assembly 3. The arc plate 41 is pulled outward so that the end of the arc plate 41 moves out of the sealing sleeve 42. At this time, one end of the sealing sleeve 42 is sleeved on the connecting platform 312, and the other end is sleeved on the outer wall of pipe 11 or pipe 2 12 under its own elastic force, so as to seal and protect the connection position between pipe 11 or pipe 2 12 and the end of the nut assembly 3 to prevent corrosion.

[0028] Furthermore, the sealing sleeve 42 is made of fluororubber (FKM / Viton) or perfluoroelastomer rubber (FFKM), which combines excellent elasticity, strong oxidation resistance, and corrosion resistance, making it the preferred choice for rust-proof protection structures. (Refer to...) Figure 7 As shown, the end of the clamping member 32 also has a support wall 412, which is sleeved on the outside of pipe one 11 or pipe two 12 to reduce the gap between the nut assembly 3 and the outer wall of pipe one 11 or pipe two 12. When the sealing sleeve 42 is sealed, the support wall 412 provides outward support to the side wall of the sealing sleeve 42 at the bend.

[0029] The second embodiment of the utility model is described below. Figure 7As shown, a set screw 5 is screwed onto one end of the arc plate 41 away from the sealing sleeve 42. After the arc plate 41 is moved to protect the connection positions of pipe 11 and pipe 212 with the nut assembly 3, the set screw 5 is tightened to press it against the outer wall of the threaded joint 22 to prevent the nut 31 from loosening during use.

[0030] The operating principle of this gas pipeline connection mechanism is as follows: Pipe 11 and pipe 212 are respectively inserted into the connecting piece 2 through the nut assembly 3. Then, the nut 31 is rotated to lock onto the threaded connecting platform 22. During the locking process, the clamping piece 32 clamps and fixes the installation position of pipe 11 and pipe 212. After pipe 11 and pipe 212 are fixed in the nut assembly 3, the arc plate 41 is pulled outward, so that the end of the arc plate 41 moves out of the sealing sleeve 42. This allows one end of the sealing sleeve 42 to fit onto the connecting platform 312, and the other end to fit onto the outer wall of pipe 11 or pipe 212 under its own elasticity. This seals and protects the connection position of pipe 11 and pipe 212 with the end of the nut assembly 3, preventing corrosion. Finally, the set screw 5 is tightened to press it tightly onto the outer wall of the threaded connecting platform 22, preventing the nut 31 from loosening during use. This gas pipeline connection mechanism not only has anti-corrosion function but also anti-loosening function, which has high practical value and improves the connection effect of gas pipelines.
