In terms of the technical functions of the water supply system, the entire water supply system should meet the user's requirements for water quality, water volume, and water pressure. The water supply system of a chiller with high precision requirements needs to maintain a certain pressure to pump water, so as to provide a certain pressure of water liquid to the chiller system.

[0003] In the prior art, a water pump is usually installed on the side wall of a water tank. The water inlet of the water pump is communicated with the first water outlet of the water tank, and the first water outlet of the water pump is communicated with the water inlet of an external system.

[0004] In view of the above related technologies, when the water tank supplies water to the chiller, since the water liquid in the chiller system needs to maintain a certain pressure, and the prior art cannot ensure the pressure during the water flow transportation process. Therefore, there is an urgent need for a water supply system that can improve the pressure stability of the water flow in the water pipe. Utility Model Content

[0005] In order to improve the pressure stability of the water flow in the water pipe, this application provides a water supply system with a certain pressure.

[0006] A water supply system with a certain pressure provided by this application adopts the following technical solutions:

[0007] A water supply system with a certain pressure includes a water tank and a water pumping assembly;

[0008] The water pumping assembly includes a main water pipe and a branch water pipe;

[0011] By adopting the above technical solutions, when supplying water to some external systems, since it is necessary to ensure the pressure stability during the water flow transportation process, by setting the branch water pipe and the pressure valve, the water flow enters the main water pipe from the water tank and is transported to the external system by the main water pipe. When the water flow pressure in the main water pipe is too high, the pressure valve is opened, so that part of the water flow in the main water pipe flows into the water tank through the branch water pipe, thereby ensuring the pressure stability of the water flow in the main water pipe, and part of the water flow enters the water tank through the branch water pipe, avoiding waste of water resources.

[0012] Optionally, the water pumping assembly further includes a water pump, the water pump is communicated with the main water pipe, and the water pump is located on the side of the branch water pipe close to the water outlet end of the main water pipe.

[0013] By adopting the above technical solution, in order to facilitate the smooth pumping of the water in the water tank into the main water pipe, a water pump is arranged on the main water pipe, and the water in the water tank is pumped out by the water pump.

When the water pump is damaged, the first valve is opened, and the water flows through the auxiliary pipe to the main water pipe, so as to ensure the smooth delivery of water.

[0016] Optionally, a second valve is communicated with the main water pipe, and the second valve is located on the side close to the water outlet end of the main water pipe.

[0019] By adopting the above technical solution, by arranging the pressure sensor, when the water flow in the main water pipe passes through the pressure sensor, if the pressure sensor detects that the water flow pressure in the main water pipe is too high, the pressure sensor sends a signal. At this time, by opening the pressure relief valve, part of the water flow in the main water pipe flows from the branch water pipe into the water tank. If the pressure sensor detects that the water flow pressure in the main water pipe is normal, the water flow continues to be delivered by the main water pipe.

Detailed implementation manners

[0035] The following further describes the present application in detail in conjunction with the attached Figures 1-3 drawings.

[0036] An embodiment of the present application discloses a water supply system with a certain pressure. Referring to Figure 1 , the water supply system with a certain pressure includes a water tank 1 and a water pumping component 2. The water pumping component 2 includes a main water pipe 21 and a branch water pipe 22. The water tank 1 is provided with a first water outlet 11. The inlet end of the main water pipe 21 is communicated with the first water outlet 11 of the water tank 1, and the outlet end is communicated with an external system. The outlet end of the branch water pipe 22 is communicated with the main water pipe 21, and the inlet end of the branch water pipe 22 is communicated with the water tank 1. A pressure relief valve 221 is arranged on the branch water pipe 22. When it is necessary to transport the water in the water tank 1 to an external cold water tank system, the water flow is transported from the water tank 1 to the external cold water tank system through the main water pipe 21. If the water flow pressure in the main water pipe 21 is relatively large, by arranging the branch water pipe 22 and opening the pressure relief valve 221, part of the water flow flows out from the branch water pipe 22 to the water tank 1 to slow down the water flow pressure in the main water pipe 21.

[0037] Referring to Figure 1 , the water pumping component 2 further includes a water pump 23. The water pump 23 is communicated with the main water pipe 21, and the water pump 23 is located on one side of the branch water pipe 22 at the inlet end of the main water pipe 21 to pump the water in the water tank 1 into the main water pipe 21 by the water pump 23.

[0038] Referring to Figure 1, when the water pump 23 is damaged, in order not to affect the flow of water from the main water pipe 21 to the external system, the pumping assembly 2 further includes an auxiliary pipe 24. The water outlet end of the auxiliary pipe 24 communicates with the main water pipe 21. The auxiliary pipe 24 is arranged between the water outlet end of the branch water pipe 22 and the water outlet end of the main water pipe 21, and a first valve 241 is connected to the auxiliary pipe 24. When the water pump 23 is damaged, the water in the water tank 1 cannot be discharged into the external system through the main water pipe 21. By setting the auxiliary pipe 24, the free end of the auxiliary pipe 24 can be connected to an external water source. Open the first valve 241, and the water flow can flow into the main water pipe 21 through the auxiliary pipe 24, and then flow from the main water pipe 21 into the external system.

[0039] Refer to Figure 1 , a second valve 211 is connected to the main water pipe 21. The second valve 211 is located on the side close to the water inlet end of the main water pipe 21 to control the on-off of the water flow from the water tank 1 into the main water pipe 21 by the second valve 211.

[0040] Refer to Figure 1 , a pressure sensor 212 is further provided on the main water pipe 21. The pressure sensor 212 is located between the water pump 23 and the water outlet end of the branch water pipe 22. When the water flow in the main water pipe 21 passes through the pressure sensor 212, if the pressure sensor 212 detects that the water flow pressure is too high, the pressure relief valve 221 is opened, and part of the water flow will further flow into the water tank 1 through the branch water pipe 22. While keeping the water flow pressure in the main water pipe 21 stable, it ensures that part of the water flow flows back into the water tank 1 to avoid waste, and further ensures that the water flow pressure flowing from the main water pipe 21 to the external cold water tank system is stable. If the pressure sensor 212 detects that the water flow pressure is stable, there is no need to open the pressure relief valve 221, and the water flow can directly flow from the main water pipe 21 to the external cold water tank system.

[0041] Refer to Figure 2 and Figure 3, To ensure that the water flowing from the main water pipe 21 into the external cold water tank 1 system contains as few impurities as possible, a water supply system with a certain pressure further includes a filtering component 3. The filtering component 3 includes a filtering tank 31 and a filtering plate 32. The filtering tank 31 is provided with a second water inlet 311 and a second water outlet 312. The second water inlet 311 is communicated with the water outlet end of the main water pipe 21. To facilitate the discharge of the water flowing through the filtering tank 31 into the external system, the pumping component 2 further includes a drain pipe 25. One end of the drain pipe 25 is communicated with the second water outlet 312. The filtering plate 32 is located inside the filtering tank 31. The outer peripheral wall of the filtering plate 32 fits against the inner peripheral wall of the filtering tank 31. Filter holes 321 are formed through the filtering plate 32 along the water flow conveying direction. The filtering plate 32 divides the filtering tank 31 into a first filtering area 322 and a second filtering area 323, so as to filter the water flowing into the filtering tank 31 by the filtering plate 32. That is, after the water flows through the first filtering area 322 and the second filtering area 323 in sequence, some impurities in the water will be blocked by the filtering plate 32, and the filtered water is discharged through the drain pipe 25.

[0042] Refer to Figure 3 , Since some impurities may adhere to the filtering plate 32, to facilitate the discharge of the impurities filtered on the filtering plate 32 by personnel, the filtering tank 31 includes a box body 313 and a cover plate 314. The cover plate 314 is detachably connected above the box body 313 to close the box body 313 by the cover plate 314. Specifically, the cover plate 314 is fixed to the box body 313 by screws. To facilitate the cleaning of the impurities on the filtering plate 32 by personnel, the filtering plate 32 is slidably connected to the box body 313 along a direction perpendicular to the water flow conveying direction. Slide grooves 3131 are formed on both sides of the box body 313 along a direction perpendicular to the water flow conveying direction. Sliders 324 are fixedly connected to both sides of the filtering plate 32. The sliders 324 are located inside the slide grooves 3131 and slide along the groove walls of the slide grooves 3131, and the outer peripheral walls of the sliders 324 completely fit against the groove walls of the slide grooves 3131, so as to facilitate the personnel to slide the filtering plate 32 out of the slide grooves 3131 to the outside of the box body 313 for cleaning.

[0043] Refer to Figure 2 , A third valve 251 is connected to the drain pipe 25 to control the on-off of the water flow from the drain pipe 25 to the external cold water tank 1.

[0044] The implementation principle of a water supply system with a certain pressure in an embodiment of this application is as follows: When the water tank 1 supplies water to the external cold water tank 1, the second valve 211 and the water pump 23 are opened. The water flow flows from the water tank 1 to the main water pipe 21, and then flows into the external system from the main water pipe 21. When the water flow passes through the pressure sensor 212, if the pressure sensor 212 detects that the water flow pressure in the main water pipe 21 is too high, the pressure relief valve 221 is opened, and part of the water flow in the main water pipe 21 will flow from the branch water pipe 22 into the water tank 1, so as to ensure the stability of the water flow pressure in the main water pipe 21; if the water pump 23 is damaged, the first valve 241 is opened, and the first valve 241 controls the external water source to flow from the auxiliary pipe 24 into the main water pipe 21, without affecting the water supply.

[0045] In order to filter the impurities in the water entering the external system, the water flow passes through the filter plate 32, and the filter plate 32 filters the impurities. Personnel can take out the filter plate 32 for cleaning.

[0046] The above are all preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
