[0003] To address the shortcomings of existing technologies, this invention provides a water sample constant regulation system.

[0021] Example 1

[0022] like Figure 1 As shown, this embodiment provides a water sample constant regulation system, including a water tank 1, a heating chamber 3, a cooling chamber 4, a main pipe 6, a left tee pipe 9, a left tee pipe 2 10, a right tee pipe 1 11, and a right tee pipe 2 12. A water temperature sensor and a heat exchange tube 5 are installed inside the water tank 1. A variable frequency water pump 2 is installed on the water tank 1. The input end of the variable frequency water pump 2 is connected to the inlet pipe, and the output end of the variable frequency water pump 2 is connected to the drain pipe 7. A water pressure sensor is installed inside the drain pipe 7. A water pump 8 is installed on the main pipe 6. A heating tube is installed inside the heating chamber 3. A semiconductor cooling chip is installed on the side wall of the cooling chamber 4. The cold end of the semiconductor cooling chip enters the cooling chamber 4, and the hot end of the semiconductor cooling chip is located outside the cooling chamber 4.

[0023] The right end of the left tee pipe 9 is connected to the left end of the main pipe 6. The left end of the left tee pipe 9 is connected to the water outlet of the heating box 3 through the water outlet pipe of the heating box. A water outlet valve for the heating box is installed on the water outlet pipe of the heating box. The bottom end of the left tee pipe 9 is connected to the top end of the pipe 13.

[0024] The right end of the left three-way pipe 210 is connected to the left end of the heat exchange pipe 5. The left end of the left three-way pipe 210 is connected to the water inlet of the heating box 3 through the water inlet pipe of the heating box. The water inlet pipe of the heating box is equipped with a water inlet valve of the heating box. The top end of the left three-way pipe 210 is connected to the bottom end of the pipe 13. The pipe 13 is equipped with valve 1.

[0025] The left end of the right tee pipe 11 is connected to the right end of the main pipe 6. The right end of the right tee pipe 11 is connected to the water inlet of the refrigeration box 4 through the refrigeration box water inlet pipe. A refrigeration box water inlet valve is installed on the refrigeration box water inlet pipe. The bottom end of the right tee pipe 11 is connected to the top end of the pipe 2 14.

[0026] The left end of the right tee pipe 2 12 is connected to the right end of the heat exchange pipe 5. The right end of the right tee pipe 2 12 is connected to the water outlet of the refrigeration box 4 through the water outlet pipe of the refrigeration box. A water outlet valve of the refrigeration box is installed on the water outlet pipe of the refrigeration box. The top end of the right tee pipe 2 12 is connected to the bottom end of the pipe 2 14. A valve 2 is installed on the pipe 2 14.

[0027] In this embodiment, through the cooperation of various components, in specific use, the heating box 3, the cooling box 4, and each pipe are filled with heat exchange liquid. After the sewage enters the water tank 1, the water temperature is detected by the water temperature sensor. If the water temperature is too high, the control system activates the heating tube to heat the heat exchange liquid, and the heat exchange tube 5 exchanges heat with the water in the water tank 1 to achieve the heating of the water temperature in the water tank 1. If the water temperature is too low, the semiconductor cooling chip is activated to cool the heat exchange liquid, and the heat exchange tube 5 exchanges heat with the water in the water tank 1 to achieve the cooling of the water temperature in the water tank 1. In this way, the water temperature in the water tank 1 is kept stable near the set value. The variable frequency water pump 2 and the water pressure sensor are set up to cooperate. The working state of the variable frequency water pump 2 is adjusted according to the water pressure value detected by the water pressure sensor, thereby regulating the water pressure. In this way, this system can regulate the water temperature and water pressure entering the analyzer, unaffected by the external environment or upstream processes, avoiding damage to the analyzer due to overheating and overpressure, and improving the service life of the analyzer.

[0028] In practical use, if water temperature needs to be heated, close valve 1, the outlet valve of the refrigeration box and the inlet valve of the refrigeration box, start water pump 8, and the heat exchange liquid enters the left three-way pipe 2 10 from heat exchange pipe 5, then enters the heating box 3, is heated by the heating pipe, and then enters the main pipe 6 from the left three-way pipe 1 9. After passing through the right three-way pipe 1 11, pipe 2 14 and right three-way pipe 2 12, it returns to the heat exchange pipe 5 to realize the heating cycle.

[0029] If it is necessary to cool the water, close valve 2, the water outlet valve of the heating box and the water inlet valve of the heating box. The heat exchange liquid in the main pipe 6 enters the refrigeration box 4 from the right three-way pipe 11. After being cooled in the refrigeration box 4, it is discharged to the right three-way pipe 2 12, and then enters the heat exchange tube 5. After passing through the left three-way pipe 2 10, the pipe 1 13 and the left three-way pipe 9, it enters the main pipe 6 to realize the refrigeration cycle.

[0030] In this way, heating and cooling can be used simultaneously through a single heat exchange tube 5, and the heating chamber 3 and cooling chamber 4 operate independently. If the heating tube or the semiconductor cooling chip is damaged, it can be repaired separately without paralyzing the entire system, thus improving the fault tolerance of the device. Furthermore, the heating chamber 3 and cooling chamber 4 are independent of the water tank 1, unlike the design where the heating and cooling components are located inside the water tank 1. This arrangement allows for repairs without disassembling the water tank 1 if the heating or cooling components are damaged, improving the convenience of maintenance.

[0031] Unstable flow rate directly affects the response time, reading drift, and measurement accuracy of various analyzers (such as pH, ORP, conductivity, and dissolved oxygen electrodes). Temperature changes alter the degree of hydrogen ion ionization, affecting pH measurements. By detecting water pressure using a water pressure sensor, the operating state of the variable frequency water pump 2 can be adjusted. With a constant diameter of the drain pipe 7 and a constant outlet water pressure, the flow rate can be stabilized, thus achieving stable flow rate regulation. Temperature is stabilized through the heat exchange tube 5. Therefore, this device achieves stable control of water sample temperature, water pressure, and flow rate.

[0032] In this embodiment, both the inlet valve and outlet valve of the heating box are solenoid valves.

[0033] In this embodiment, both the inlet valve and outlet valve of the refrigeration box are solenoid valves.

[0034] In this embodiment, both valve one and valve two are solenoid valves.

[0035] In this embodiment, the heating box inlet valve, heating box outlet valve, cooling box inlet valve, cooling box outlet valve, valve one, and valve two are all solenoid valves to achieve overall control of the control system.

[0036] In this embodiment, the water tank 1, heating tank 3, and cooling tank 4 are all supported by support columns.

[0037] In this embodiment, the water tank 1 has a water inlet hole on its top wall, and a water inlet valve is installed at the water inlet hole. The water tank 1 also has a drain hole on its bottom wall, and a drain valve is installed at the drain hole. The water inlet hole on the top wall of the water tank 1 allows water to enter the tank. The drain hole on the bottom wall allows residual water to be drained after use.

[0038] In this embodiment, a heat exchange tube support frame is provided inside the water tank 1, and the heat exchange tube 5 is placed on the heat exchange tube support frame. The heat exchange tube support frame is provided in this embodiment to support the heat exchange tube 5.
