Description

Technical Field

[0001] The utility model belongs to the technical field of water system disinfection, and more specifically, relates to a water supply system with an easy-to-switch disinfection mode. Background Art

[0002] There are generally two designs for water supply system pipes: one is to design a full-circulation pipeline in view of the characteristics of pure water that needs to circulate; the other is to choose the main pipeline for circulation design, and the water branch pipeline adopts a parallel circulation design. However, when the full-circulation pipeline is designed, the water volume at the peak water consumption point is small; when the main pipeline is designed for circulation, the water branch pipeline adopts a parallel circulation design, and the circulation volume of each branch water pipe is difficult to control due to the different resistance drops of each water branch pipeline during disinfection, resulting in uneven disinfection.

[0003] For example, the patent number CN202321597821.9 and the name "An Automated Disinfection System for Medical Pure Water" discloses an automated disinfection system for medical pure water, which is applied to the field of medical pure water equipment. The system includes a set of pure water supply circuits and their control devices. The pure water supply circuit includes a pure water circuit starting with an electric water inlet valve, which is sequentially connected to a pure water tank, a pure water pump, a water point, an electric three-way valve, and finally connected back to the pure water tank; further, it also includes a medicine dispensing barrel, an electric agitator, and a pipette pump. The medicine dispensing barrel is connected to the pure water tank through a pipette pump, and the medicine dispensing barrel is provided with an electric agitator. This product uses PLC technology to program the disinfection process. After adding only a certain amount of disinfectant, the disinfection procedure can be automatically performed to thoroughly disinfect the pure water pipeline.

[0004] It can be seen from the patent specification and its drawings that the water supply method still adopts a single full-circulation pipeline design. Although the added disinfectant can disinfect the entire pipeline, it ignores the water pressure in the peak water supply section and is only suitable for use at fewer water points. It does not have the function of switching pipeline modes. Utility Model Content

[0010] The utility model discloses a water supply system with an easy-to-switch disinfection mode. The water supply part is also provided with a return pipe, one end of the return pipe is connected to a pure water tank, and the other end of the return pipe is connected to an outlet of a water delivery pipe.

[0011] Through the above arrangement: adding a return pipe can make the water supply part a circulation system on the one hand, and save water on the other hand.

[0012] The utility model discloses a water supply system with an easy-to-switch disinfection mode. The filter part is also provided with an external salt box, which is connected to a softening filter and contains a sodium chloride solution.

[0013] Through the above setting: adding a salt box, the required solution can be continuously added to the softening filter, reducing the manual operation time of the staff.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By adopting the design of selecting the main pipeline for circulation and the water-using branch pipeline for parallel circulation as the main body, and adding a riser electric valve and a short-circuit electric valve to the design, the design is changed into a full-circuit pipeline design that can be automatically switched. This allows the water supply system to take into account the advantages of both designs at the same time, ensure water pressure during peak water use periods, and ensure full pipeline disinfection during disinfection, thereby increasing the scope of application of the technical solution, reducing the cost, and having great promotion significance.

[0023] Depend on Figure 1 , Figure 2 and Figure 3 A water supply system with an easy-to-switch disinfection mode is shown, comprising a first power source, a filtering part and a water supply part connected in sequence through a water pipeline 1, wherein: the water supply part comprises a pure water tank 13, a second power source and a water point connected in series in sequence through the water pipeline 1, the water point is a plurality of water branches 9 connected in parallel on the water pipeline 1, standpipe electric valves 10 are alternately arranged on both sides of the parallel water branches 9, and a short-circuit electric valve 12 is arranged on the even-numbered water branches 9 in parallel; the filtering part comprises a mechanical filter 3, a first activated carbon filter 4, a second activated carbon filter 4, a softening filter 5 and a safety filter 6 connected in series in sequence through the water pipeline 1; the first power source and the second power source are both composed of two or more pure water pumps 2 connected in parallel; the water supply part is also provided with a return pipe 12, one end of the return pipe 12 is connected to the pure water tank 13, and the other end of the return pipe 12 is connected to the outlet of the water pipeline 1; the filtering part is also provided with an external salt box 8, the salt box 8 is connected to the softening filter 5, and the salt box 8 contains sodium chloride solution.

[0024] Working principle and method

[0025] Normal water supply:

[0026] The riser electric valves 10 are all open; the short-circuit electric valves 11 are all closed;

[0027] Reference Figure 3(The arrow in the figure indicates the direction of pure water flow). The water outlet in the pure water tank is interlocked with the inverter of pure water pump 2. When responding to pressure fluctuations, it reacts quickly to achieve constant pressure water supply. The same-path pipeline design is adopted, and a flow balance valve is used to control the balance of water volume in each branch. According to this design, the distance from the delivery pump to the farthest water point is short, and the pipeline pressure loss is small. With the same pipeline specification, the end water volume is larger than that of the full-circulation pipeline design.

[0028] Disinfecting the water supply:

[0029] The switch riser electric valves 10 are all closed; the short-circuit electric valves 11 are all opened;

[0030] Reference Figure 2 , making the pipe network structure become a full circulation type. At this time, the return water pressure of the pipeline is detected and interlocked with the pure water pump 2 inverter to ensure that the circulation volume of each branch is equal and the pure water in the pipeline is in a turbulent state. At this time, the disinfectant can flow through various parts of the pipeline at a large flow rate for balanced disinfection.

[0031] It should be noted that during disinfection, in order to allow the disinfectant to flow through various parts of the pipeline at a large flow rate, that is, the water pressure cannot be in a dispersed state, under the normal water supply mode, each water use point may be using water, causing pressure dispersion, and causing the disinfectant to be unable to flow through various parts of the pipeline and to gather at the pressure relief point.

[0032] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
