AI Technical Summary
The existing medical central pure water system lacks control valves in the circulation pipeline, resulting in the pump shutdown if water leakage occurs, and all relevant water departments on the entire circulation pipeline have no water available, making maintenance inconvenient.
A medical pure water multi-floor water supply system has been designed. By setting up separate water supply pipes, return pipes and valves on each floor, independent water supply and return water management of each floor can be realized. When water leakage occurs, only the valves on the corresponding floor can be closed for inspection and maintenance, and will not affect the water supply on other floors.
This system allows the valves on the corresponding floor to be closed separately for inspection when water leakage occurs, avoiding the risk of pump shutdown in the entire system, making it easier to repair, and improving the reliability and maintenance convenience of the system.

Abstract
Description
Technical Field
[0001] This application relates to the technical fields of water purification and water supply, and particularly to a multi-floor water supply system for medical pure water. Background Art
[0002] At present, the equipment of the medical central pure water system used in hospitals generally pumps the water in the pure water tank through sterilization, filtration and other treatments and then transports it to the circulation pipeline, and then transports it to each water-using department through the circulation pipeline. The circulation pipeline generally consists of a single supply pipeline and a single return pipeline. After the supply pipeline passes through the departments with the same water quality one by one, it then flows back to the pure water tank through the return pipeline, forming a closed loop. In the whole circulation pipeline, generally not too many control valves are set, and only a few valves such as the outlet of the water supply pump and the return port of the pure water tank are used for control.
[0003] However, the circulation pipeline composed of a single supply pipeline and a single return pipeline results in that the supply pipeline on each floor is the main pipeline of the circulation pipeline. If a leak occurs and the pump stops, all relevant water-using departments on the circulation pipeline will have no water available, and it is inconvenient for maintenance.

[0025] As Figure 1 shown, an embodiment of the present application provides a multi - floor water supply system for medical pure water, including: a pure water tank 100, a first water supply pump 200, a second water supply pump 300, a sterilizer 400, and a filter 500.
[0026] The water inlet of the pure water tank 100 is connected to the reverse osmosis system. An inlet valve 101 and an inlet flow meter 102 are connected in series between the reverse osmosis system and the water inlet of the pure water tank 100 in sequence. The water outlet of the pure water tank 100 is connected to the water inlet of the first water supply pump 200. The water outlet of the first water supply pump 200 is connected to the water inlet of the sterilizer 400. The water outlet of the sterilizer 400 is connected to the water inlet of the filter 500. After the water outlet of the filter 500 is connected in series with a conductivity meter 105, a main water supply valve 106, and a main water supply pressure gauge 107 in sequence, it is connected to the main water supply pipe 601. A drain pipe is installed between the conductivity meter 105 and the main water supply valve 106, and a second drain valve 112 is installed on the drain pipe.
[0027] In practical applications, the sterilizer 400 can be an in-line ultraviolet sterilizer or other sterilizers; the filter 500 can be a microporous filter or other filters, and the present application does not make specific limitations on this.
[0028] The main water supply pipe 601 is connected to the floor water supply pipes 603 of each floor from top to bottom. The floor water supply pipe 603 is connected to the water inlet of the water-using device. The water outlet of the water-using device is connected to the floor return pipe 604. The floor return pipes 604 of each floor are respectively connected to the main return pipe 602.
[0029] The main return pipe 602 is connected to the water return port of the pure water tank 100 after being connected in series with a main return water pressure gauge 108 and a main return water valve 109 in sequence at one end close to the water return port of the pure water tank 100.
[0030] A floor water supply pressure gauge 605 and a floor water supply stop valve 606 are connected in series on the floor water supply pipe 603, and a floor return water pressure gauge 607 and a floor return water stop valve 608 are connected in series on the floor return pipe 604. The floor water supply pressure gauge 605 and the floor water supply stop valve 606 are installed on the side close to the main water supply pipe 601, and the floor return water pressure gauge 607 and the floor return water stop valve 608 are installed on the side close to the main return pipe 602.
[0031] Exhaust valves 609 are respectively installed at the highest positions of the main water supply pipe 601 and the main return pipe 602.
[0032] A first water supply valve 201 is arranged in front of the water inlet of the first water supply pump 200, and a first check valve 202 is arranged at the water outlet of the first water supply pump 200.
[0033] A second water supply pump branch is arranged between the water inlet end of the first water supply valve 201 and the water outlet end of the first check valve 202. A second water supply valve 301, a second water supply pump 300, and a second check valve 302 are connected in series on the second water supply pump branch.
[0034] A first pressure gauge 103 and a pressure transmitter 104 are connected in series between the first check valve 202 and the sterilizer 400.
[0035] A liquid level gauge 110 is provided in the pure water tank 100. A drain pipe is also installed at the bottom of the pure water tank 100, and a first drain valve 111 is installed on the drain pipe.
[0036] In daily use, only one of the first water supply pump 200 and the second water supply pump 300 is turned on. The second water supply pump 300 serves as a backup for the first water supply pump 200. When the first water supply pump 200 fails or needs to be repaired, the second water supply pump is turned on. Therefore, usually, the first water supply valve 201, the first water supply pump 200, and the first check valve 202 are kept open, the second water supply valve 301, the second water supply pump 300, and the second check valve 302 are kept closed, and the second water supply pump branch is usually in an open circuit state.
[0037] The water supply from the original water tank 100 passes through the first water supply valve 201, the first water supply pump 200, and the first check valve 202, and then the water pressure is detected and adjusted by the first pressure gauge 103 and the pressure transmitter 104, and then enters the sterilizer 400 for sterilization treatment, and then enters the filter 500 for filtering and removing impurities. The water supply after the above treatment is detected by the conductivity meter 105 for the quality of the treated water, and then is supplied to the main water supply pipe 601 through the main water supply valve 106. The main water supply pressure gauge 107 can detect the water supply pressure of the main water supply pipe 601.
[0038] The main water supply pipe 601 supplies water from the top floor to the floor water supply pipes 603 of each floor. Figure 1 Only the middle three floors are shown for illustration. The present application does not limit the number of floors of the building. In practice, there may be more or fewer floors, but water needs to be supplied to each floor from the top floor downwards. After the floor water supply pipes 603 of each floor supply water to the water using devices at the water using points of each floor, the return water is collected to the main return water pipe 602 through the floor return water pipes 604. Finally, the main return water pipe 602 leads the return water back to the original water tank 100. Before the return water enters the original water tank 100, the return water pressure can also be detected by the main return water pressure gauge 108, and the opening and closing of the main return water valve 108 can be adjusted to control the return water to enter the original water tank 100.
[0039] When supplying water to each floor, the exhaust valves 609 at the top ends of the main water supply pipe 601 and the main return water pipe 602 can be opened, which is beneficial to accelerating the filling of the floor water supply pipes 603 and the floor return water pipes 604 of each floor with water.
[0040] Since the floor water supply pipes 603 of each floor are equipped with floor water supply pressure gauges 605 and floor water supply stop valves 606, and the floor return water pipes 604 are equipped with floor return water pressure gauges 607 and floor return water stop valves 608, when the water pressure of a certain floor is unstable, it can be judged whether it is a problem of the overall water supply pressure of the system or a problem of the water supply pressure of a single floor by checking the floor water supply pressure gauges 605 and the floor return water pressure gauges 607 of each floor.
[0041] When it is determined that there is a water supply pressure problem on a certain floor, it is possible to further judge whether the pressure problem lies on the side of the floor water supply pipe 603 or the water usage point side according to the floor water supply pressure gauge 605 and the floor return water pressure gauge 607 of that floor, that is, whether the pressure problem is caused by water supply or water usage. Furthermore, the water pressure of that floor can be changed by adjusting the floor water supply stop valve 606 and / or the floor return water stop valve 608 of that floor.
[0042] When a fault occurs in the water supply system of a certain floor or maintenance is required, the floor water supply stop valve 606 and the floor return water stop valve 608 of that floor can be closed separately, and then the treatment can be carried out without affecting the normal water use of other floors.
[0043] When the liquid level gauge 110 in the pure water tank 100 is at a low water level, the inlet valve 101 opens, and water is added to the pure water tank 100 through the self - reverse osmosis system. The inlet flowmeter 102 can check the speed of water inlet, so as to adjust the inlet valve 101 accordingly and control the water filling speed of the pure water tank 100.
[0044] When the pure water tank 100 needs to be maintained, the inlet valve 101, the first water supply valve 201 and the second water supply valve 301 can be closed, and the first drain valve 111 is opened. The pure water tank 100 can then drain the water through the drain pipe.
[0045] In addition, the medical pure water multi - floor water supply system of the present application can also be maintained section by section. When it is determined that there are no faults in the pure water tank 100 and the water usage ends of each floor, only the first water supply pump 200, the second water supply pump 300, the sterilizer 400 and the filter 500 can be maintained. At this time, the first water supply valve 201, the second water supply valve 301 and the main water supply valve 106 can be closed, and the second drain valve 112 is opened to drain the water supply in only this section of equipment through the drain pipe.
[0046] It can be understood that when the system needs to be emptied as a whole, the first drain valve 111 and the second drain valve 112 can also be used simultaneously, that is, all valves in the system except the inlet valve 101 are opened, and the water supply in the system is emptied through the first drain valve 111 and the second drain valve 112 at the same time.
[0047] In the present application, each floor is separately set as a water supply branch, and stop valves and pressure gauges are installed at the water supply and return ends of each floor, so that the pressure conditions of each floor can be understood in time, facilitating the solution of problems such as unstable pressure and inconvenient maintenance.
[0048] The present application also adds exhaust valves at the highest points of the main water supply pipe and the main water outlet pipe, which can solve the problem that it takes a long time for pure water to fill the pipeline.
[0049] In the embodiment of the present application, the multi-floor medical pure water supply system includes: a pure water tank, a first water supply pump, a sterilizer, and a filter; the outlet of the pure water tank is connected to the inlet of the first water supply pump, the outlet of the first water supply pump is connected to the inlet of the sterilizer, the outlet of the sterilizer is connected to the inlet of the filter, the outlet of the filter is connected to the main water supply pipe, the main water supply pipe is connected to the floor water supply pipes of each floor from top to bottom, the floor water supply pipe is connected to the inlet of the water-using device, the outlet of the water-using device is connected to the floor return pipe, the floor return pipes of each floor are respectively connected to the main return pipe, and the main return pipe is connected to the return water inlet of the pure water tank; a floor water supply stop valve is installed on the floor water supply pipe, and a floor return water stop valve is installed on the floor return pipe. In this application, separate water supply pipes, return pipes, and valves are provided for each floor. When a leak occurs, only the valves corresponding to the affected floor need to be closed for maintenance, without affecting the water supply to other floors, which is convenient for repair.
[0050] The above is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
