[0002] Water temperature regulating valves play a vital role in many fields such as bathing equipment, industrial cooling systems, and heating systems. However, a significant technical challenge in the manufacturing process of traditional water temperature regulating valves is the complexity of their internal pipe structure. The internal pipe structure of the valve body of a traditional water temperature regulating valve usually includes multiple areas such as the water inlet, the water outlet, and the flow control area. These areas are interconnected by a complex pipe network to achieve precise water temperature regulation. However, due to the large number of pipes and complex shapes, the processing is extremely difficult. Casting is usually performed by casting, and except for the position of the pipes, they are all solid. The amount of raw materials used is large, and the product weight is heavy. High-end thermostatic valves are all cast from brass materials, and the raw material price is high. In addition, castings also require advanced CNC machine tools and skilled operators, which significantly increases the production cost of traditional water temperature regulating valves. Therefore, it is necessary to solve the above technical problems. Summary of the invention

[0031] Please also read Figures 1 to 6 Now, a split water temperature regulating valve structure provided in an embodiment of the present application is described. The split water temperature regulating valve structure includes a valve body 100, a water distribution core 200, a valve core 300 and a compression nut 400. Among them:

[0032] The valve body 100 forms three ports that are interconnected. The water distribution core 200 is arranged inside the valve body 100 and forms an inlet pipe interface 201 for connecting the inlet pipe 701 and an outlet pipe interface 202 for connecting the outlet pipe 702. It also forms an inlet hole 203 connected to the inlet pipe interface 201 and an outlet hole 204 connected to the outlet pipe interface 202. The inlet pipe interface 201 and the outlet pipe interface 202 are respectively facing two ports of the valve body 100, and the inlet hole 203 and the outlet hole 204 are facing the remaining port of the valve body 100. The valve core 300 extends from the ports of the valve body 100 corresponding to the water inlet hole 203 and the water outlet hole 204 into the interior of the valve body 100 and abuts against the water distribution core 200. The valve core 300 forms a water inlet hole 301 communicating with the water inlet hole 203 and a water outlet hole 302 communicating with the water outlet hole 204. The compression nut 400 is threadedly connected to the valve body 100 and presses the valve core 300 against the water distribution core 200. The water flow in the external water inlet pipe 701 can flow into the valve core 300 through the water inlet pipe interface 201, the water inlet hole 203 and the water inlet hole 301 in sequence. After the water temperature is adjusted by the valve core 300, the mixed water can flow out to the external water outlet pipe 702 through the water outlet hole 302, the water outlet hole 204 and the water outlet pipe interface 202 in sequence.

[0033] According to the above structure provided in the present embodiment, since in the split water temperature regulating valve structure provided in the present embodiment, the valve body 100, the water distribution core 200 and the valve core 300 are split structures, wherein the water distribution core 200 is arranged inside the valve body 100 and forms a water inlet pipe interface 201 for connecting the water inlet pipe 701, a water outlet pipe interface 202 for connecting the water outlet pipe 702, and a water inlet hole 203 and a water outlet hole 204 for docking with the valve core 300, the valve core 300 extends into the interior of the valve body 100 from one of the ports of the valve body 100 and abuts on the water distribution core 200 to communicate with the water distribution core 200. In this way, the split-structure valve body 100, water distribution core 200 and valve core 300 can be separately processed and then assembled into a water temperature regulating valve with complete functions. In particular, the valve body can be designed as a simple three-way structure, and the water distribution core is a thin shell structure. While ensuring water permeability and strength, the use of raw materials is reduced, and the production cost of the water temperature regulating valve is significantly reduced, which is far superior to the existing technology.

According to the above structure provided in this embodiment, the lower flange 205 and the upper flange 206 adapted to the cross-sectional shape of the pipe inside the valve body 100 can be better and stably installed inside the valve body 100, thereby helping to reduce the volume of other parts of the water distribution core 200, and helping to further reduce the production cost of the split water temperature regulating valve structure provided in this embodiment.

[0035] In another embodiment of the present application, please refer to Figures 1 to 6 The water distribution core 200 has a middle flange 207 for forming a water inlet hole 203 and a water outlet hole 204. The edge of the middle flange 207 forms a protective ring 208. The valve core 300 is mounted on the water distribution core 200 through the protective ring. According to the above structure provided in this embodiment, the protective ring 208 can make the valve core 300 more stably abut against the water distribution core 200, which is conducive to the split water temperature regulating valve structure provided in this embodiment to operate stably for a longer time.

[0036] In another embodiment of the present application, please refer to Figures 1 to 6 The valve core 300 is formed with a plurality of positioning posts 303 protruding toward the water distribution core 200, and the water distribution core 200 is formed with a plurality of positioning holes 209 adapted to the positioning posts 303. The valve body 100 is engaged with the water distribution core 200 through the positioning posts 303 and the positioning holes 209. According to the above structure provided in this embodiment, the valve core 300 and the water distribution core 200 can be more stably connected through the mutual cooperation of the positioning posts 303 and the positioning holes 209, which is conducive to the split water temperature regulating valve structure provided in this embodiment to operate stably for a longer period of time.
