[0019] The exemplary embodiments of the present utility model will be described below with reference to the drawings. Embodiment

[0020] A medium circulation control system includes a liquid inlet pipe 1 and a liquid outlet pipe 2. On one side of the liquid inlet pipe 1, there is a liquid inlet joint 3. On one side of the liquid inlet joint 3, there is a first connecting pipe 4. On one side of the first connecting pipe 4, there is a cooling circuit connected to the first connecting pipe 4 and the liquid inlet joint 3. A complete reflux system is provided in the cooling circuit. On one side of the cooling circuit, there is a system main control solenoid valve 5 for controlling the on / off of the medium in the system. The system main control solenoid valve 5 is used to control the on / off of the whole medium in the system. On one side of the system main control solenoid valve 5, there is a second connecting pipe 6. On one side of the second connecting pipe 6, there is a flow sensor 7. One side of the flow sensor 7 is connected to the liquid outlet pipe 2. The flow sensor 7 is used to detect the flow rate in the pipeline.

[0021] Preferably, the cooling circuit includes a temperature sensor 8 and a reflux connecting pipe 9. The temperature sensor 8 is arranged on one side of the first connecting pipe 4. The reflux connecting pipe 9 is connected between the temperature sensor 8 and the system main control solenoid valve 5. During the process of medium flow, the medium first passes through the temperature sensor 8 and then through the system main control solenoid valve 5. The temperature sensor 8 can detect the temperature of the medium in the system. If the medium temperature is too high, the system main control solenoid valve 5 needs to be closed to cut off the medium flow direction. If the medium temperature is normal, the system main control solenoid valve 5 is normally opened to enable the medium to continue flowing backward.

[0022] Preferably, the cooling circuit further includes a branch solenoid valve 10, a cooling liquid inlet pipe 11, and a cooler 12. There is a bypass branch on the reflux connecting pipe 9. The branch solenoid valve 10 is connected to the branch of the reflux connecting pipe 9. The cooling liquid inlet pipe 11 is connected to the branch solenoid valve 10 and is distributed in a downward direction. The cooler 12 is arranged at the lower end of the cooling liquid inlet pipe 11. When the medium temperature is too high, since the system main control solenoid valve 5 has been closed, at this time, the branch solenoid valve 10 needs to be opened to guide the medium to flow into the cooling circuit. The medium enters the cooling liquid inlet pipe 11 through the branch solenoid valve 10 and finally reaches the cooler 12. Under the action of the cooler 12, the temperature gradually decreases until it reaches the standard medium temperature.

[0023] Preferably, the cooling circuit further includes a pump body inlet pipe 13, a pump body 14, and a return outlet pipe 15. The pump body inlet pipe 13 is provided at the lower end of the cooler 12 and is connected to the cooler 12. The other end of the pump body inlet pipe 13 is provided with a pump body 14. The pump body inlet pipe 13 is connected to the inlet end of the pump body 14. The return outlet pipe 15 is connected to the outlet end of the pump body 14. The other end of the return outlet pipe 15 is connected to the upper end of the inlet joint 3. The cooled medium is returned to the position of the inlet joint 3 through the action of the pump body 14 and participates in the system circulation again. By mixing with the low-temperature medium, the medium in the system can also be cooled down.

[0024] An emergency shunt branch 16 is provided on one side of the flow sensor 7. The two ends of the emergency shunt branch 16 are respectively connected between the flow sensor 7 and the outlet pipe 2. A shunt solenoid valve 17 is provided on the emergency shunt branch 16. When the pressure sensor detects that the pressure value in the system is too high, the shunt solenoid valve 17 needs to be opened at this time to distribute the medium to the emergency shunt branch 16 and relieve the pressure on the main pipeline.

[0025] The above is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to this; for those skilled in the art of the present invention and related technical fields, based on the technical solution idea of the present invention, the expansions, operation methods, and data replacements should all fall within the protection scope of the present invention.
