[0034] Example 1

[0035] like Figure 1-4 As shown, this embodiment provides a medical test pure water circulation and disinfection system, including a water tank 1 and a booster pump 2, and also includes a circulation pipe 3 connected to several water use points 31; the water tank 1 includes a water supply pipe 11 connected to its bottom, a water inlet pipe 12 and a return pipe 13 connected to its top, and a disinfection device 14 installed inside it; the water supply pipe 11 is connected to the inlet of the booster pump 2, and the outlet of the booster pump 2 is connected to the first branch pipe 4 and the second branch pipe 5; the inlet of the return pipe 13 is connected to the third branch pipe 6 and the fourth branch pipe 7; one end of the circulation pipe 3 is connected to the first branch pipe 4 and the fourth branch pipe 7, and the other end is connected to the second branch pipe 5 and the third branch pipe 6; the first branch pipe 4, the second branch pipe 5, the third branch pipe 6 and the fourth branch pipe 7 are respectively installed with a first valve 41, a second valve 51, a third valve 61 and a fourth valve 71.

[0036] The efficient circulation of pure water is achieved through the cooperation of the circulation pipe 3 and the branches. At the same time, a disinfection device 14 is integrated in the water tank 1 to ensure the safety of water quality during the circulation process and effectively avoid the breeding of microorganisms such as bacteria and viruses.

[0037] Furthermore, the water inlet pipe 12 is equipped with a water inlet valve 121, and the water inlet valve 121 is connected to a filter device 8. The filter device 8 includes a reverse osmosis device 81 disposed before the water inlet valve 121. The filter device 8 also includes a deionization device 82 disposed between the water inlet valve 121 and the reverse osmosis device 81.

[0038] By installing the reverse osmosis device 81 and the deionization device 82 on the water inlet pipe 12, harmful substances such as impurities and ions in the water can be effectively removed, thereby improving the purity and quality of the pure water.

[0039] Furthermore, the disinfection device 14 is preferably an ultraviolet disinfector, which is kept on when in use to disinfect all pure water passing through the water tank 1. The disinfection device 14 can also be an external ozone generator, which generates ozone when in use and inputs it into the water tank 1 for disinfection.

[0040] Furthermore, when the first valve 41, the third valve 61 and the water inlet valve 121 are opened and the other valves are closed, after the booster pump 2 is turned on, the circulation pipeline 3 is in a forward circulation state.

[0041] Furthermore, when the second valve 51, the fourth valve 71 and the water inlet valve 121 are opened and the other valves are closed, after the booster pump 2 is turned on, the circulation pipeline 3 is in a reverse circulation state.

[0042] Furthermore, when the first valve 41 , the second valve 51 and the water inlet valve 121 are opened and the other valves are closed, after the booster pump 2 is turned on, water enters both ends of the circulation pipe 3 .

[0043] It should be noted that, because the water consumption varies at different times, it is necessary to switch the opening and closing states of each valve according to the water consumption of the reagents to maintain sufficient water supply. For example, a two-way water supply mode is adopted during peak water consumption to meet the water volume of each water point 31 in the circulation pipeline 3. At other times when water consumption is less, a forward and reverse alternating circulation mode is adopted to eliminate the dead space during one-way water supply and ensure the quality of pure water.

[0044] Through the precise control of multiple valves, the circulation pipe 3 can realize multiple circulation modes such as forward circulation, reverse circulation and simultaneous water inflow at both ends, meeting the water demand in different scenarios and improving the flexibility and adaptability of the system.

[0045] Example 2

[0046] like Figure 1As shown, components identical or corresponding to those in Example 1 are designated by the corresponding reference numerals. For simplicity, only the differences from Example 1 are described below. This second embodiment differs from Example 1 in that at least one backup pipeline 15 is provided on the top of the water tank 1. The backup pipeline 15 is equipped with a backup valve 151, and the backup pipeline 15 can be connected to an additional water source as needed. The water supply pipeline 11 is also connected to a drainage branch 111, which is equipped with a drainage valve 112. The backup pipeline 15 can also serve as an inlet for chemical disinfectants. The system will periodically shut down to chemically disinfect the interior of the water tank 1 and the various pipelines. After disinfection, the liquid in the water tank 1 is drained by opening the drainage valve 112 and the valves at each water point 31.

[0047] By providing the drainage branch 111 and the backup pipeline 15, which are used to drain the water in the water tank 1 and provide an additional access port, the reliability and emergency response capability of the system are enhanced.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
