Stainless steel pipes, also known as stainless steel, are austenitic chromium-nickel stainless steels with excellent oxidation resistance and corrosion resistance. They are mainly used for fluid transmission of various media and are widely used in pipelines for petroleum, chemical, food and other industries, as well as mechanical structural components.

[0003] However, existing stainless steel water pipes mostly use seamless welding technology to connect the pipes. But when the pipes are partially damaged, it is difficult to replace the damaged pipes, and the replacement cost is high. In addition, stainless steel pipes are prone to cracking when subjected to high pressure or impact from the fluids transported inside, which can lead to leakage of transport resources. Therefore, it is not convenient to promote its use.

[0004] To address this problem, this application provides a high-pressure resistant stainless steel water pipe. Utility Model Content

[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a high-pressure resistant stainless steel water pipe, including an outer pipe assembly 1, an inner pipe assembly 2, and a connecting assembly 3. The outer pipe assembly 1 includes an outer water pipe 10 and a bushing ring 12. The bushing ring 12 is disposed inside the outer water pipe 10. The inner pipe assembly 2 is fixedly installed inside the outer pipe assembly 1. The inner pipe assembly 2 is used to seal and position the water pipe installation. The connecting assembly 3 is disposed at one end of the outer pipe assembly 1 and the inner pipe assembly 2. The connecting assembly 3 is used to connect the outer pipe assembly 1.

[0024] like Figure 2 As shown, a pressure gauge 11 is fixedly installed inside the outer water pipe 10, and the bottom end of the pressure gauge 11 is fixedly installed inside the inner water pipe 20, so that the fluid pressure in the inner water pipe 20 can be monitored through the pressure gauge 11.

[0025] like Figure 4 As shown, the outer water pipe 10 has an installation hole 13 inside, the bushing ring 12 is fixedly installed inside the installation hole 13, and the inner water pipe 20 is fixedly installed inside the bushing ring 12. By setting the inner water pipe 20 inside the outer water pipe 10, and setting the bushing ring 12 between the outer water pipe 10 and the inner water pipe 20, the inner water pipe 20 is wrapped by the bushing ring 12. Under the combined action of the outer water pipe 10, the inner water pipe 20 and the bushing ring 12, the inner water pipe 20 can withstand greater fluid pressure, preventing the leakage of transportation resources caused by the rupture of the stainless steel water pipe.

[0026] like Figure 3 and Figure 4As shown, the inner pipe assembly 2 includes an inner water pipe 20 and a positioning ring 21. The positioning ring 21 is movably connected to one end of the inner water pipe 20. Positioning grooves 23 are provided at both ends of the inner water pipe 20. Positioning blocks 22 are provided on both sides of the positioning ring 21. The positioning blocks 22 are located inside the positioning grooves 23. The positioning grooves 23 and positioning ring 21 on the inner water pipe 20 and the outer water pipe 10 are used to position and connect the inner water pipe 20 and the outer water pipe 10, which facilitates subsequent connection.

[0027] like Figure 4 As shown, a first sealing gasket 24 is provided on the outside of the inner water pipe 20. The other end of the first sealing gasket 24 is movably connected to one end of the outer water pipe 10. A stop block 26 is fixedly connected inside the inner water pipe 20. The positioning ring 21 is pushed by the outer water pipe 10 to contact the first sealing gaskets 24 on both sides. The first sealing gasket 24 seals the connection between the positioning ring 21 and the outer water pipe 10 to prevent the fluid being transported from leaking out.

[0028] like Figure 4 As shown, a second sealing gasket 25 is fixedly installed inside the stop block 26. The other side of the second sealing gasket 25 is movably connected to one side of the positioning ring 21. A fluid channel 27 is provided inside the inner water pipe 20. The stop block 26 inside the inner water pipe 20 pushes the positioning ring 21 to move, so that the positioning ring 21 is tightly attached to the second sealing gasket 25, thus sealing the connection between the positioning ring 21 and the inner water pipe 20.

[0029] like Figure 2-4 As shown, the connecting assembly 3 includes a connecting ring 30 and a connecting bolt 31. The connecting bolt 31 is threaded inside the connecting ring 30. The connecting ring 30 is located at one end of the external water pipe 10. A connecting groove 32 is provided inside the connecting ring 30. Connecting plates 14 are fixedly installed at both ends of the external water pipe 10. The connecting plates 14 are located inside the connecting groove 32. One end of the connecting bolt 31 is movably connected to the outside of the connecting plate 14. Tightening the connecting bolt 31 pushes the connecting plate 14, and at the same time, the connecting ring 30 brings the connecting plates 14 on the two external water pipes 10 closer together and seals them with a sealing gasket. This eliminates the need for welding to connect the stainless steel water pipes, reducing replacement costs when the pipes are damaged.

[0030] The working principle of this high-pressure resistant stainless steel water pipe will be explained in detail below.

[0031] like Figure 1-4As shown, when using this high-pressure resistant stainless steel water pipe, connect the two water pipes end to end, then tighten the connecting bolt 31. The connecting bolt 31 pushes the connecting plate 14, and at the same time, the connecting ring 30 brings the connecting plates 14 on the two outer water pipes 10 closer together. Simultaneously, the stop block 26 inside the inner water pipe 20 pushes the positioning ring 21 to move, so that the positioning ring 21 is tightly pressed against the second sealing gasket 25, sealing the connection between the positioning ring 21 and the inner water pipe 20. The outer water pipe 10 also pushes the positioning ring 21 to contact the first sealing gaskets 24 on both sides, sealing the connection between the positioning ring 21 and the outer water pipe 10 through the first sealing gaskets 24, preventing leakage of the transported fluid. Through the combined action of the connecting ring 30 and the connecting bolt 31, there is no need to... The stainless steel water pipes are connected by welding technology, which reduces the replacement cost when the pipes are damaged. An inner water pipe 20 is installed inside the outer water pipe 10, and a bushing ring 12 is installed between the outer water pipe 10 and the inner water pipe 20. The bushing ring 12 wraps around the inner water pipe 20. With the combined action of the outer water pipe 10, the inner water pipe 20 and the bushing ring 12, the inner water pipe 20 can withstand greater fluid pressure, preventing leakage of transport resources caused by the rupture of the stainless steel water pipe. The fluid pressure in the inner water pipe 20 can be monitored by the pressure gauge 11. The positioning groove 23 and the positioning ring 21 on the inner water pipe 20 and the outer water pipe 10 are used to position and connect the inner water pipe 20 and the outer water pipe 10, which facilitates subsequent connection.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
