Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-3The present invention provides a technical solution: an ultra-high pressure water heating device, comprising an outer tube 1, wherein both ends of the outer tube 1 are respectively provided with an ultra-high pressure water inlet 11 and a water outlet 12, wherein the ultra-high pressure water inlet 11 is a tapered inlet with a large mouth facing outward, which is convenient for water flow to enter, and the inner part of the outer tube 1 is respectively provided with a wear-resistant rod 4 and a wear-resistant ring 7, wherein the wear-resistant rod 4 and the wear-resistant ring 7 are both made of superhard material, and the inner side surface of the outer tube 1 is provided with a first positioning step 5, wherein the first positioning step 5 is connected with the wear-resistant rod seat 3 by clamping, and the setting of the first positioning step 5 can be used for the wear-resistant rod seat 3 is used to fix the position of the wear-resistant rod 4, and then fix the position of the wear-resistant rod 4. The wear-resistant rod seat 3 is fixedly connected to the rod portion 403 of the wear-resistant rod 4. Two second water flow channels 14 are symmetrically arranged at the upper and lower ends of the wear-resistant rod seat 3. A cavity 2 is left between the wear-resistant rod seat 3 and the wear-resistant ring 7. The arrangement of the cavity 2 facilitates the water flow to slow down. A second positioning step 6 is arranged on the inner side of the outer tube 1. The second positioning step 6 is connected to the wear-resistant ring 7 by clamping. The arrangement of the second positioning step 6 facilitates the fixing of the position of the wear-resistant ring 7. The wear-resistant rod 4 includes a protrusion 401 on the head and a protrusion 402 on the protrusion 403. 01 connected with the inclined surface 402 and the rod 403, the surface of the protrusion 401 of the wear-resistant rod 4 is a smooth surface, which is convenient for the diversion of high-pressure water and prevents water from splashing. The wear-resistant ring 7 is connected to the inner side of the outer tube 1 through a sealing ring 8 to improve the sealing between the wear-resistant ring 7 and the outer tube 1. The wear-resistant ring 7 includes a conical surface 701 and a first water flow channel 702 arranged at one end of the inner part thereof. The protrusion 401 of the wear-resistant rod 4 extends into the wear-resistant ring 7 and the inclined surface 402 of the wear-resistant rod 4 and the conical surface 701 of the wear-resistant ring 7 form a circle of equally spaced heating gaps 13. The wear-resistant ring One end of 7 is tightly fitted with a hexagonal pressing cap 9, and a third water flow channel 15 is arranged in the middle position of the hexagonal pressing cap 9 along its axial direction. The third water flow channel 15 corresponds to the position of the first water flow channel 702. The outer side surface of the hexagonal pressing cap 9 is provided with an external thread 10, and the inner side surface of the outer tube 1 is provided with an internal thread matching the external thread 10.

At the same time, the hexagonal pressing cap 9 is threadedly connected to the outer tube 1, which facilitates the installation and disassembly of the hexagonal pressing cap 9.

[0020] During use: high-pressure water is introduced into the outer tube 1 through the ultra-high-pressure water inlet 11. After the high-pressure water passes through the heating gap 13, the water flow velocity increases sharply. After passing through the heating gap 13 and entering the cavity 2, the water flow velocity is forced to drop rapidly, and the kinetic energy of the water is converted into the internal energy of the water. The water temperature increases and the pressure decreases. Then, the water flows out through the second water flow channel 14 and the water flow outlet 12. The water after flowing out is high-temperature water. The water pressure and water temperature of the hot water flowing out can be adjusted by changing the distance of the heating gap 13. The change in the distance of the heating gap 13 is adjusted by the position of the first positioning step 5 and the second positioning step 6 in the outer tube 1.
