Detailed Implementation
[0020] The invention will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-10According to an embodiment of the present invention, a high-safety leak-proof metal hose structure includes a first hose 1 and a second hose 2. A fixing ring 3 is fixedly connected to one end of both the first hose 1 and the second hose 2. A connector 4 is provided at the other end of both the first hose 1 and the second hose 2. A wear-resistant layer 5 is provided on the side of the fixing ring 3. The wear-resistant layer 5 is located on the inner annular surface of the first hose 1 and the second hose 2, forming a protective cavity 6 between the wear-resistant layer 5 and the inner annular surface of the first hose 1 and the second hose 2. A capsule tube 7 is provided on the outer annular surface of the wear-resistant layer 5. The capsule tube 7 contains... A sealing cavity 8 is provided, and a repair agent 9 is injected into the sealing cavity 8. Both ends of the first hose 1 and the second hose 2 are provided with connectors 4 and fixing rings 3, which facilitates the subsequent connection and sealing of the two sets of pipes for future use. The wear-resistant layer 5 prevents the transported gas or liquid from directly contacting the inside of the pipe. The wear-resistant layer 5 also increases the wear resistance of the pipe, reduces wear on the inner surface of the first hose 1, and improves its service life. In addition, the repair agent 9 is provided in the capsule tube 7 to facilitate timely filling and repair of the torn surface of the wear-resistant layer 5, reducing the risk of leakage.
[0021] The connector 4 has a connecting plate 10 on its end face, a sealing bearing 11 on its outer ring surface, a sealing tube 12 on its surface, a thread on its inner ring surface, a positioning nut 13 on its outer ring surface, and an installation tube 14 on the side of the fixing ring 3. The sealing bearing 11 facilitates the rotation of the sealing tube 12 and avoids conflict with the connector 4 when rotating the sealing tube 12. It also facilitates the subsequent screwing of the sealing tube 12 onto the threaded tube 17.
[0022] Please see Figure 7 and Figure 8 As shown, the capsule tube 7 is fixedly connected to the outer ring surface of the wear-resistant layer 5. The repair agent 9 contains repair resin and catalyst. A leak alarm 15 is provided on the side of the fixing ring 3. The detection probe 28 on the detection end of the leak alarm 15 is inserted into the protective cavity 6. The surface of the fixing ring 3 is provided with a threaded groove 16. By fixing the capsule tube 7 to the outer ring surface of the wear-resistant layer 5, when the wear-resistant layer 5 may tear after long-term use, the surface of the capsule tube 7 attached to the surface of the wear-resistant layer 5 will crack, so that the repair agent 9 injected inside the capsule tube 7 will flow out to fill and repair the tear on the surface of the wear-resistant layer 5, further improving the service life of the wear-resistant layer 5. When a leak occurs, the gas or liquid will first flow into the protective cavity 6, and then be detected by the detection probe 28 of the leak alarm 15. When a leak is detected, the leak alarm 15 will sound an alarm to remind the staff to repair it, so as to avoid leakage affecting safety issues. The leak alarm 15 is a common gas or liquid leak alarm device. The leak alarm 15 can be a liquid alarm or other alarm.
[0023] Please see Figures 1-6 As shown, the fixed ring 3 has a threaded tube 17 on its side and a groove 18 on its side. A sealing gasket 19 is placed in the groove 18. The sealing gasket 19 has an annular plate structure, and its inner diameter is larger than the outer diameter of the threaded tube 17. A limiting groove 20 is opened on the surface of the mounting tube 14. The limiting groove 20 has a "T"-shaped plate structure and a sealing sleeve 21 is placed in the limiting groove 20. The sealing sleeve 21 is fixedly connected in the limiting groove 20. Several sets of limiting grooves 20 are opened on the surface of the mounting tube 14. The sealing gasket 19 is fixedly connected in the groove 18. When the sealing tube 12 is screwed onto the threaded tube 17, one end of the sealing tube 12 squeezes the sealing gasket 19, which facilitates the sealing of the first hose 1 and the second hose 2 after connection. In addition, the connecting plate 10 is inserted into the limiting groove 20. On the one hand, it prevents the second hose 2 from rotating after connection. On the other hand, it works with the sealing sleeve 21 in the limiting groove 20 to increase the positioning stability and sealing effect of the connecting plate 10.
[0024] Please see Figure 1 and Figure 2 As shown, the positioning nut 13 is fixedly connected to the surface of the sealing tube 12. A positioning groove 22 is provided on the surface of the positioning nut 13, and a fixing rod 23 is inserted into the positioning groove 22. A positioning plate 24 is provided on the surface of the fixing rod 23, and a through hole is provided on the surface of the positioning plate 24. A limit bearing 25 is provided in the through hole, and a limit bolt 26 is fixedly connected to the inner ring of the limit bearing 25. The limit bolt 26 is screwed into the threaded groove 16. After the sealing tube 12 is screwed onto the threaded tube 17, one end of the fixing rod 23 is first inserted into the positioning groove 22, and then the limit bolt 26 is rotated in conjunction with the limit bearing 25, so that one end of the limit bolt 26 is screwed into the threaded groove 16. The setting of the fixing rod 23 and the limit bolt 26 prevents the positioning nut 13 from rotating due to pipe vibration, thereby improving the sealing and stability of the connection between the pipes. In addition, the positioning plate 24 can also act as a handle, making it convenient for workers to lift and move the first hose 1 and the second hose 2 through the positioning plate 24.
[0025] Please see Figures 4-10 As shown, the sealing tube 12 is fixedly connected to the outer ring surface of the sealing bearing 11. Several sets of connecting plates 10 are provided, and all sets of connecting plates 10 are fixedly connected to the end face of the connector 4. The connecting plate 10 has a "T" shaped plate structure. A protective sleeve 27 is provided on the outer ring surface of the sealing tube 12. The protective sleeve 27 is made of rubber and has an overall ring structure. The sealing tube 12 is screwed onto the threaded tube 17 through the thread on the inner ring surface. When the sealing tube 12 is screwed onto the threaded tube 17, it squeezes the protective sleeve 27. The protective sleeve 27 covers and protects the sealing gasket 19 to prevent sunlight from irradiating the sealing gasket 19 when the pipe is placed outdoors, thus affecting the service life of the sealing gasket 19.
[0026] Through the above-described solution of the present invention, the wear-resistant layer 5 is provided on the inner annular surface of the first hose 1. The wear-resistant layer 5 improves the wear resistance of the material and the first hose 1. In addition, when the surface of the wear-resistant layer 5 is torn, the capsule tube 7 will rupture, which facilitates the outflow of the repair agent 9 inside the capsule tube 7. The repair agent 9 repairs the torn part of the wear-resistant layer 5, avoiding leakage problems caused by pipeline tearing. The cooperation between the first hose 1, the wear-resistant layer 5 and the capsule tube 7 further improves the safety of pipeline transportation.
