It should be noted that the installation position of the temperature-regulating diverter valve of the utility model is not limited to the pipeline 1, and a shell or a box body can be used. The temperature-regulating diverter valve comprises a valve body 2, a valve cover 3, a push rod 4, and a push rod sleeve 5. The valve body 2 is a bottle body with an opening at one end, the valve cover 3 is arranged at the open end of the valve body 2, the push rod sleeve 5 is arranged in the valve body 2, and the push rod sleeve 5 cooperates with the valve cover 3 to seal the open end of the valve body 2; one end of the push rod 4 is inserted in the push rod sleeve 5, and the other end extends out of the valve body 2 and is connected to a push rod seat 6 arranged on the pipeline 1, and a temperature sensing component is provided between the valve body 2 and the push rod sleeve 5. In this embodiment, the temperature sensing component is paraffin; a valve 7 is fixed to the outer end of the valve cover 3, and a sliding vane 8 integrally formed therewith is provided on one side of the valve 7, and a flow port 11 cooperating with the valve 7 and a flow port 2 12 cooperating with the sliding vane 8 are provided on the pipeline 1. The end of the pipe 1 away from the flow port 11 is the inflow channel of the liquid. The coolant flows into the pipe 1 from the inflow channel and contacts the valve body 2. When the temperature is low, the valve plate 7 closes the flow port 11, and the flow port 2 12 is in an open state, and the coolant flows from the flow port 2 12 into the path 2; when the temperature rises, the temperature sensing component expands and squeezes the push rod 4. The valve body 2 moves toward the flow port 2 12 under the reverse thrust of the push rod 4, and the valve 7 opens the flow port 11, and the slide plate 8 closes the flow port 2 12. The path 2 is closed, and the coolant flows from the flow port 11 into the path 1, realizing the switching of different paths of the coolant. The valve 7 and the slide plate 8 of the temperature-regulating diverter valve in the utility model are integrally formed, and the switching of different paths of the coolant is realized through one valve, and there is no need to set two valves at different positions, which simplifies the structure and reduces the assembly difficulty and manufacturing cost of the valve.

The spring 9 is sleeved on the outside of the valve body 2, one end of which is fixedly connected to the valve body 2, and the other end is fixedly connected to the support 10. The end of the valve body 2 away from the opening is inserted into the support 9 and slidably connected to the support 9. The support 9 guides the movement of the valve body 2, thereby ensuring the moving direction of the slide 8. The support 10 is against the supporting boss 14 of the pipeline 1 through the spring 9. When disassembling and maintaining, the thermostatic diverter valve can be removed as a whole by simply pulling out the push rod 4 from the push rod seat, without the need for other installation and matching, and the disassembly and assembly are simple and convenient.

When closed, the disc can completely cover the flow port 11 and exceed the flow port 11, which is a surface seal. Compared with a line seal, it has better sealing performance and makes the path switching of the liquid more accurate.

[0029] In addition, if Figure 2 , 3 As shown, the slide 8 is an arc-shaped plate extending along the side of the valve, the pipeline 1 is provided with an arc-shaped slide groove 13, the slide 8 is set in the slide groove 13 and slidably connected with the slide groove 13, and the second flow port 12 is provided on the slide groove 13 at one end away from the first flow port 11. When closed, the slide 8 can completely cover the second flow port 12 and exceed the second flow port 12, which is a surface seal. Compared with a line seal, it has better sealing performance and makes the path switching of the liquid more accurate.

[0030] The valve cover 3 is fixedly connected to the valve body 2 by riveting. Figure 1-4 As shown, the open end of the valve body 2 is provided with a step 21, one end of the push rod sleeve 5 is provided with a sealing portion 51, and the other end is a telescopic portion, and the sealing portion 51 is pressed onto the step 21 through the valve cover 3.

Through the cooperation and sealing of the sealing surface 1 52 and the sealing surface 2 31, the sealing performance is good, paraffin leakage is avoided, and thus the failure of the temperature-controlled diverter valve is avoided.
