[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-5 A stainless steel corrugated pipe for water heating shown in the figure comprises a stainless steel corrugated hose 1, a first joint 4 is fixedly provided at one end of the stainless steel corrugated hose 1, an internal thread 5 is provided on one side of the first joint 4, a first sealing ring 6 is provided on one side of the first joint 4, a telescopic sleeve 7 is movably connected inside the first joint 4, a spring 8 is movably provided outside the telescopic sleeve 7, a second sealing ring 9 is provided on one side of the first joint 4, a sealing groove 10 is provided on the surface of one end of the first joint 4, a first sealing ring 11 is movably connected inside the sealing groove 10, an adapter 12 is movably connected outside the first joint 4, and a second joint 13 is fixedly provided on the other side of the stainless steel corrugated hose 1, an adapter 12 for connecting water heating is sleeved outside the first joint 4, the rotating adapter 12 is threadedly connected to the internal thread 5, and when the adapter 12 is rotated and pushed forward, the telescopic sleeve 7 and the external spring 8 are arranged to achieve a buffering and squeezing effect, so that the second sealing ring 9 and the telescopic sleeve 7 squeeze the inside of the adapter 12, and the first sealing ring 11 is squeezed tightly against the inside of the adapter 12, thereby improving the sealing effect.

[0026] like Figure 1 and Figure 2As shown, the interior of the stainless steel corrugated hose 1 is provided with a wear-resistant material 2, and the wear-resistant material 2 is made of epoxy resin. Through the setting of the wear-resistant material 2, it is avoided that when warm water is transported inside the stainless steel corrugated hose 1, there are some granular impurities that cause internal damage and leakage.

[0027] like Figure 1 and Figure 2 As shown, an anti-corrosion layer 3 is provided inside the wear-resistant part 2. The material of the anti-corrosion layer 3 is three-layer polyethylene. The setting of the anti-corrosion layer 3 can avoid the occurrence of internal corrosion due to long-term use.

[0028] like Figure 1 and Figure 3 As shown, the telescopic sleeve 7 is arranged inside the first joint 4, and the spring 8 is arranged outside the telescopic sleeve 7. The first joint 4 is movably connected with the telescopic sleeve 7. Through the setting of the spring 8, the telescopic sleeve 7 is driven to expand and contract inside the first joint 4, so that the telescopic sleeve 7 squeezes the inside of the adapter 12, thereby improving the sealing effect.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the sealing groove 10 is opened at one end of the first joint 4, and the first sealing ring 11 is movably connected to the sealing groove 10. Through the setting of the first sealing ring 11, the first sealing ring 11 and the inside of the adapter 12 are squeezed, and the first sealing ring 11 is squeezed tightly against the adapter 12, thereby improving the sealing effect. The setting of the sealing groove 10 facilitates the disassembly and replacement of the first sealing ring 11.

[0030] like Figure 1 and Figure 5 As shown, the outside of the second joint 13 is movably connected with a nut 14, and one side of the second joint 13 is movably connected with a valve 15. One side of the valve 15 is provided with an external thread 16, and one side of the external thread 16 is provided with a second sealing ring 17. The external thread 16 on one side of the valve 15 is pressed against the second joint 13, and the nut 14 on the outside of the second joint 13 is rotated to make the two sealed and connected, thereby facilitating disassembly and installation by the staff.

[0031] The practical working principle of the present invention is as follows: first, the adapter 12 for supplying water heating is put on the first connector 4, and then the adapter 12 is rotated to be threadedly connected with the internal thread 5. When the adapter 12 is rotated and moved, the telescopic sleeve 7 inside the first connector 4 and the spring 8 outside play the role of extrusion buffering, so that the second sealing ring 9 and the telescopic sleeve 7 squeeze the inside of the adapter 12, and the first sealing ring 11 is squeezed tightly against the inside of the adapter 12, thereby improving the sealing between the two. Next, the second connector 13 at the other end of the stainless steel corrugated hose 1 is connected to the valve 15, and the second connector 13 and the valve 15 are sealed by rotating the nut 14 outside the second connector 13. The wear-resistant 2 inside the stainless steel corrugated hose 1 can prevent some particulate impurities from causing internal damage and leakage when the stainless steel corrugated hose 1 is transporting warm water. The anti-corrosion layer 3 is set to avoid internal corrosion caused by long-term use. In this way, the use process of the stainless steel corrugated hose for water heating is completed.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
