As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0030] See also Figure 1-2 The embodiment of the utility model provides a detachable integrated water circuit of a pressure relief valve, including a water circuit housing 1, a valve core assembly 2, a pressure relief valve 3 and a heating assembly 4. A total water inlet 5 is provided on the water circuit housing 1, a water tank inlet 6, a mixed water pipeline 7 and a heat exchange pipeline 8 are provided in the water circuit housing 1, and the valve core assembly 2 is respectively connected to the total water inlet 5, the water tank inlet 6, the mixed water pipeline 7 and the heat exchange pipeline 8. The total water inlet 5 flows into the valve core assembly 2 after passing cold water. The valve Under the control of an external control device, the core assembly 2 flows cold water to the water tank inlet 6, or flows cold water to the heat exchange pipeline 8, or flows the water that flows into the heat exchange pipeline 8 and undergoes heat exchange before mixing with cold water to the mixed water pipeline 7. It can be understood that the heat exchange pipeline 8 includes a heat exchange inlet pipeline 81 and a heat exchange outlet pipeline 82. The heat exchange inlet pipeline 81 is respectively connected to the valve core assembly 2 and the external heat exchange equipment, and the heat exchange outlet pipeline 82 is respectively connected to the valve core assembly 2 and the external heat exchange equipment. The heating assembly 4 is arranged on the outside of the waterway housing 1, and a secondary heating water inlet 9 and a total water outlet 10 are also opened on the waterway housing 1. The heating assembly 4 is respectively connected to the mixed water pipeline 7 and the secondary heating water inlet 9. The secondary heating water inlet 9 is also connected to the total water outlet 10. The water flowing out of the mixed water pipeline 7 is heated by the heating assembly 4 after undergoing partial water heat exchange, achieving secondary heating, which is conducive to ensuring that the temperature of the water flowing out of the total water outlet 10 meets the user's needs. Among them, the water tank water inlet 6 is connected to the external water tank.

[0031] Please continue reading Figure 1 The utility model is provided with a valve body connection port 11 on the water channel housing 1. The valve body connection port 11 is connected to the main water inlet 5 or the heat exchange pipeline 8. The pressure relief valve 3 is detachably connected to the valve body connection port 11. The pressure relief valve 3 is used to open when the pressure in the pipeline exceeds the preset pressure of the pressure relief valve 3, thereby reducing the pressure in the pipeline. The setting of the valve body connection port 11 facilitates the direct connection of the pressure relief valve 3 to the water channel housing 1 without the need to be set on the outside of the outer protective shell, thereby improving the aesthetics of the overall structure of subsequent products. At the same time, it is also conducive to the development of products in the direction of integration and miniaturization, and is conducive to improving the competitiveness of products. The detachable design also facilitates the disassembly, installation, replacement and maintenance of the pressure relief valve 3. The specific setting position of the valve body connection port 11 can be determined based on the actual pressure measurement conditions at the main water inlet 5 and the heat exchange pipeline 8, and it can be set at the pipe port with higher pressure.

[0032] See also Figure 2 The pressure relief valve 3 of the present invention includes a pressure relief valve housing 12 and a pressure relief assembly 13. The pressure relief assembly 13 is partially arranged in the pressure relief valve housing 12 and partially located at one end of the pressure relief valve housing 12. A water channel connection port 14 and a pressure relief port 15 are provided on the pressure relief valve housing 12, wherein the water channel connection port 14 is sealed and connected with the valve body connection port 11, that is, the connection ports of the two are connected, and the connection gap between the two is sealed by a double O-ring, a single O-ring, a flat gasket or a combination of a single O-ring and a flat gasket. These methods can better achieve a sealing effect and help reduce the possibility of leakage.

[0033] Please continue reading Figure 2 The water channel connection port 14 is in an inserted shape, and a fixing hole structure 16 is provided in the connecting section of the water channel connection port 14. Threaded holes 17 matching the fixing hole structure 16 are opened at both ends of the valve body connection port 11. When the water channel connection port 14 is sealed and connected with the valve body connection port 11, external bolts pass through the fixing hole structure 16 and are detachably connected with the threaded holes 17 to realize the connection between the pressure relief valve 3 and the water channel housing 1. The threaded connection method can ensure the relative stability of the structural connection and is also easy to disassemble.

[0034] Preferably, the valve body connection port 11 of the present invention is opened at 30-90° on the water channel housing 1, that is, the valve body connection port 11 is opened vertically or at a certain angle, and can be set according to the actual shape of the water channel housing 1, which is conducive to the connection of the pressure relief valve 3 close to the water channel housing 1, thereby improving the integration of the product and facilitating the development of the product towards miniaturization.

[0035] See also Figure 3 As a variation of the pressure relief valve 3, it lacks the aforementioned fixing hole structures 16 at either end of the valve body connection port 11. Instead, it includes a fixing plate 25. The center portion of the fixing plate 25 is arched and matches the shape of the pressure relief valve housing 22. Fixing hole structures 26 are provided on either side. After the waterway connection port 24 and the valve body connection port 11 are sealed and connected, the pressure relief valve 3 is removably connected to the waterway housing 1 via the fixing plate 25, thereby securing the pressure relief valve housing 22 between the fixing plate 25 and the waterway housing 1. Specifically, this is achieved by removably connecting the fixing hole structures 26 to the threaded holes 17 via external bolts. The provision of the fixing plate 25 relatively secures the pressure relief valve housing 22 through surface contact, improving the stability of the connection structure. In this embodiment, the fixing plate 25 and the pressure relief valve housing 22 are split structures, including but not limited to this. The middle structural part of the fixing plate 25 can also be an integrated structure with the pressure relief valve housing 22. At this time, the two components are integrated to prevent loss. It is only necessary to connect the fixing plate 25 to the threaded hole 17 with external bolts so that the pressure relief valve housing 22 is relatively fixed.

[0036] See also Figure 4 As a variation of the pressure relief valve 3, the above-mentioned fixing hole structures 16 are not provided at both ends of the valve body connection port 11. The water channel connection port 34 is in an embedded shape and a first thread 27 is provided on the circumferential side of the water channel connection port 34. A second thread (not shown) matching the first thread 27 at the water channel connection port 34 is provided on the valve body connection port 11. The valve body connection port 11 and the water channel connection port 34 are detachably connected through the threaded connection between the first thread 27 and the second thread. That is, the water channel connection port 34 of the pressure relief valve housing 32 can be directly threadedly connected to the valve body connection port 11, making disassembly and installation faster.
