[0039] The following will describe in detail some embodiments of the present utility model in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0040] Referring to Figure 1 , this embodiment provides a temperature and pressure control system for chilled circulating water, including a water storage tank 100, a conditioning tank 200, and a circulating water inlet pipeline and a circulating water return pipeline 400 connected between the two; the circulating water inlet pipeline is configured to make the circulating water flow from the water storage tank 100 to the conditioning tank 200, and the circulating water inlet pipeline at least includes a circulating water pump 330, a cooling component 340, and a pressure control component. The circulating water pump 330, the cooling component 340, and the pressure control component are in fluid communication. Among them, the circulating water pump 330 is configured to provide power for the flow of the circulating water, the cooling component 340 is configured to cool the circulating water, and the pressure control component is configured to control the pressure of the circulating water flowing from the water storage tank 100 to the conditioning tank 200; the circulating water return pipeline 400 is configured to make the circulating water flow from the conditioning tank 200 back to the water storage tank 100.

[0041] In the temperature and pressure control system for chilled circulating water of this embodiment, the circulating water inlet pipeline can make the circulating water flow from the water storage tank 100 to the conditioning tank 200, and the circulating water return pipeline 400 can make the circulating water flow from the conditioning tank 200 back to the water storage tank 100. Therefore, the switching of the circulating water between the water storage tank 100 and the conditioning tank 200 can be realized, and the circulating flow can be achieved; specifically, the circulating water inlet pipeline at least includes a circulating water pump 330, a cooling component 340, and a pressure control component, and the circulating water pump 330, the cooling component 340, and the pressure control component are in fluid communication. During this process, the circulating water pump 330 can provide power for the flow of the circulating water, the cooling component 340 can cool the circulating water, and the pressure control component can control the pressure of the circulating water flowing from the water storage tank 100 to the conditioning tank 200. Therefore, this control system can provide water with a certain pressure and temperature for the conditioning tank 200, can control the temperature of the circulating water, and can quickly cool down. Since both the temperature and pressure of the circulating water can be controlled, the requirements of the conditioning tank 200 for chilled circulating water are met. In addition, this control system operates stably, has high reliability, and requires less maintenance work, ensuring the smooth progress of production.

[0042] In this embodiment, the circulating water inlet pipeline includes a main flow pipeline 310 and a branch pipeline 320. One end of the main flow pipeline 310 is connected to the water storage tank 100, and the other end is connected to the interlayer of the conditioning tank 200; the pressure control component includes a return pipe regulating valve 350 and a pressure gauge 360; the circulating water pump 330, the cooling component 340, and the pressure gauge 360 are arranged in sequence on the main flow pipeline 310; the return pipe regulating valve 350 is arranged on the branch pipeline 320, and one end of the branch pipeline 320 is connected to the water storage tank 100, and the other end is connected to the pipeline between the circulating water pump 330 and the cooling component 340.

[0043] According to the reading of the pressure detection table 360, the pressure of the circulating water on the main flow pipeline 310 can be obtained, and the opening degree of the reflux pipe regulating valve 350 can be adjusted as needed to adjust the flow rate of the circulating water.

[0044] Optionally, the circulating water pump 330 can be a multi-stage water pump. In this embodiment, the pressure detection table 360 is connected to the main flow pipeline 310 through a tee.

[0045] Exemplarily, the cooling assembly 340 can adopt a refrigeration unit. Specifically, the refrigeration unit can set the temperature of the circulating water according to requirements, thereby ensuring that the temperature and pressure of the cooling circulating water are stably adjustable. It overcomes the technical deficiencies of the original circulating system and achieves the purpose of stable production to meet the process requirements.

[0046] Refer to Figure 1 , a first stop valve 370 is respectively provided at the inlet and outlet ends of the circulating water pump 330.

[0047] Correspondingly, a first stop valve 370 is also provided at the port where the circulating water inlet pipeline is close to the connection with the dispensing tank 200.

[0048] Further, a filter is provided near the inlet end of the circulating water pump 330.

[0049] Exemplarily, the filter adopts a Y-type filter 380.

[0050] On the basis of the above embodiment, please continue to refer to Figure 1 , the water storage tank 100 includes a liquid level control assembly; the liquid level control assembly includes an upper liquid level detector 510, a lower liquid level detector 520 and a water replenishing solenoid valve 530; both the upper liquid level detector 510 and the lower liquid level detector 520 are arranged on the water storage tank 100 for respectively detecting the highest water level and the lowest water level of the water storage tank 100; the water storage tank 100 is connected with a water replenishing pipeline, and the water replenishing solenoid valve 530 is arranged on the water replenishing pipeline.

[0051] During specific use, when the lower liquid level detector 520 detects that the water level in the water storage tank 100 reaches the lowest water level, it will send a water replenishing signal to the water replenishing solenoid valve 530, and the water replenishing solenoid valve 530 receives the water replenishing signal and opens, so that the replenishing water flows into the water storage tank 100 through the water replenishing pipeline. When the upper liquid level detector 510 detects that the water level in the water storage tank 100 reaches the highest water level, it will send a stop water replenishing signal to the water replenishing solenoid valve 530, and the water replenishing solenoid valve 530 receives the stop water replenishing signal and closes.

[0052] By providing the upper liquid level detector 510, the lower liquid level detector 520 and the water replenishing solenoid valve 530 to form a liquid level control assembly, the liquid level of the water storage tank 100 can be ensured to be always within the normal range.

[0053] Please refer to again Figure 1 , the circulating water return pipeline 400 includes a second stop valve 410; wherein, the port of the circulating water inlet pipeline communicating with the conditioning tank 200 is lower than the port of the circulating water return pipeline 400 communicating with the conditioning tank 200, and both are communicated with the interlayer of the conditioning tank 200, so that the circulating water in the conditioning tank 200 can flow back to the water storage tank 100.

[0054] In summary, the working process of the control system of this embodiment is as follows: when the circulating water pump 330 is turned on, the circulating water in the water storage tank 100 will flow into the conditioning tank 200 through the Y-type filter 380, the refrigeration unit, and the first stop valve 370. At the same time, the circulating water flowing out of the conditioning tank 200 will flow back to the water storage tank 100 through the second stop valve 410 to complete the cycle.

[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
