[0035] The water storage tank 10 can be a tank-shaped structural member made of medical grade stainless steel by bending and welding, and a support frame is installed at the bottom thereof for ground installation. A window is provided at the top of the water storage tank 10, and a cleaning device extends from the window into the water storage tank 10. For example, the cleaning device can be composed of a high-pressure pump and a rotating spray head assembly, which can realize regular automatic cleaning of the inner wall of the water storage tank 10 to prevent contamination of the stored purified water.

[0036] One end of the water supply pipeline 20 is connected to the drain port of the water storage tank 10, and the water delivery pump 30 is arranged in the water supply pipeline 20. Optionally, the water delivery pump 30 can be a horizontal centrifugal pump, which provides sufficient power for the purified water to flow in the pipeline.

[0037] The water inlet of the first three-way piece is connected to the other end of the water supply pipeline 20, the first water supply branch pipe 40 and the second water supply branch pipe 50 are arranged in parallel, and the water inlet of the first water supply branch pipe 40 and the water inlet of the second water supply branch pipe 50 are respectively connected to the first drain port and the second drain port of the first three-way piece.

[0038] The second three-way piece is connected with one end of the return water pipeline 60, the drain port of the first water supply branch pipe 40 and the drain port of the second water supply branch pipe 50, and the other end of the return water pipeline 60 is connected with the water inlet of the water storage tank 10; the return water heat exchanger 70 is arranged in the water supply pipeline 20. The second three-way piece can be any one of a three-way valve, a three-way pipe, etc., which can be selected according to actual needs.

[0039] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: when the purified water parallel operation module 100 of this solution is working, the purified water stored in the water storage tank 10 is discharged through its drain port and flows into the water supply pipeline 20, The water delivery pump 30 is started to provide purified water to flow continuously in the water supply pipeline 20 and flow into the first water supply branch pipe 40 and the second water supply branch pipe 50 through the first tee simultaneously, thereby realizing that the first water supply branch pipe 40 and the second water supply branch pipe 50 arranged in parallel can simultaneously supply water to the water-using places; thereafter, the unused purified water continues to flow along the first water supply branch pipe 40 and the second water supply branch pipe 50, and finally converges into the return water pipeline 60 through the second tee, and the purified water return flowing in the return water pipeline 60 flows into the return water heat exchanger 70 so that the purified water return water is disinfected and sterilized by the heat of heat exchange, and finally the purified water return water flows back to the pure water tank for recycling; compared with the prior art, the present scheme adopts a single water delivery pump 30 in conjunction with the first water supply branch pipe 40 and the second water supply branch pipe 50 connected in parallel to realize a dual-circuit water supply scheme, and has a simple structure, convenient control operation, and occupies less installation space.

[0040] Please continue to refer to FIG. 1. In an optional embodiment, the purified water parallel operation module 100 further includes a tank bottom sampling valve 80, a tank bottom discharge valve 90 and a waste pipe 90a. The tank bottom sampling valve 80 is arranged in the water supply pipe 20, one end of the waste pipe 90a is connected to the water supply pipe 20, and the tank bottom discharge valve 90 is arranged in the waste pipe 90a. In actual work, when the temperature changes, the storage conditions in the tank deteriorate, etc., the quality of the purified water stored in the water storage tank 10 will deteriorate and cannot meet the use requirements. At this time, when the purified water flows from the water storage tank 10 into the water supply pipe 20, the tank bottom sampling valve 80 can be opened to sample the purified water and conduct quality inspection. When it is confirmed that the purified water quality does not meet the use requirements, the tank bottom discharge valve 90 can be opened while the water delivery pump 30 is kept closed, so that the purified water discharged from the water storage tank 10 can be discharged from the system through the waste pipe 90a.

[0041] In addition, in another optional embodiment, the purified water parallel operation module 100 further includes a water supply valve 90b, which is disposed in the water supply pipeline 20 and arranged upstream of the water delivery pump 30. When the sample inspection confirms that the purified water meets the use requirements, the tank bottom discharge valve 90 does not need to be opened. At this time, it is only necessary to open the water supply valve 90b and start the water delivery pump 30 at the same time, so that the purified water flowing in the water supply pipeline 20 can flow into the water delivery pump 30, and the water delivery pump 30 provides flow force and flows into the first water supply branch pipe 40 and the second water supply branch pipe 50 at the same time.

[0042] Optionally, the water supply valve 90b can be a manual valve or an electrically controlled valve, and the specific valve can be flexibly selected according to actual needs.

[0043] Furthermore, the purified water parallel operation module 100 also includes a water outlet sampling valve 90c and a first pressure gauge 90d, which are sequentially arranged in the water supply pipeline 20 and are both arranged downstream of the water delivery pump 30. In order to prevent the purified water from being mixed with impurities and affecting the water quality during the process of flowing through the water supply pipeline 20, the water supply valve 90b and the water delivery pump 30, the water outlet sampling valve 90c can be operated to perform secondary sampling quality inspection for judgment. In addition, the pressure gauge arranged in the water supply pipeline 20 can be used to display the water pressure in the water supply pipeline 20 in real time, so that the staff can intuitively obtain the readings to eliminate the potential safety hazards caused by excessive pressure.

[0044] Please continue to refer to FIG. 1 . In an optional embodiment, a manual diaphragm valve 90e is provided on both the first water supply branch pipe 40 and the second water supply branch pipe 50. The manual diaphragm valve 90e is provided to facilitate the staff to manually switch the opening and closing state and the opening degree of the valve, so as to flexibly adjust the flow rate of purified water flowing through the first water supply branch pipe 40 and the second water supply branch pipe 50.

[0045] Furthermore, on the basis of the above embodiment, a proportional regulating valve 90f and a flow meter 90g are also provided on the first water supply branch pipe 40 and the second water supply branch pipe 50, and the proportional regulating valve 90f and the flow meter 90g are arranged downstream of the manual diaphragm valve 90e in sequence. The return water flow of the first water supply branch pipe 40 and the second water supply branch pipe 50 is detected by the flow meter 90g and linked with the proportional regulating valve 90f, so that the return water flow of the first water supply branch pipe 40 and the second water supply branch pipe 50 can be the same, and the flow meter 90g also needs to be linked with the water delivery pump 30 to ensure that the total return water and branch return water flow rates are adapted.

[0046] In addition, based on any of the above embodiments, the purified water parallel operation module 100 further includes a first temperature transmitter 90h and a second temperature transmitter 90i, wherein the first temperature transmitter 90h is disposed in the return water pipeline 60 and arranged upstream of the return water heat exchanger 70, and the second temperature transmitter 90i is disposed in the return water pipeline 60 and arranged downstream of the return water heat exchanger 70. The first temperature transmitter 90h and the second temperature transmitter 90i are respectively installed upstream and downstream of the return water heat exchanger 70, so as to facilitate the control of the temperature of the purified water return water and ensure the temperature requirements of pasteurization or superheated water sterilization.

[0047] Please continue to refer to FIG. 1 . In another optional embodiment, the purified water parallel operation module 100 further includes a return water sampling valve and a second pressure gauge 90j, which are respectively arranged in the return water pipeline 60. The return water sampling valve is arranged to facilitate sampling of the purified water return water. The pressure gauge is arranged to facilitate real-time detection of the water pressure in the return water pipeline 60 to ensure safe operation.

[0048] Furthermore, the purified water parallel operation module 100 also includes a conductivity detection device and a discharge valve 90k, which are respectively connected to the return water pipeline 60, and the discharge valve 90k is arranged downstream of the conductivity detection device. The conductivity detection device can be set to perform conductivity detection on the purified water return water flowing back to the water storage tank 10 to determine whether the conductivity value meets the standard. When the test result shows that the conductivity value does not meet the set value, the discharge valve 90k can be opened to discharge the purified water return water.

[0049] In addition to the above, the present application also provides a pharmaceutical water system, including the purified water parallel operation module 100 as described in any of the above embodiments.
