DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0027] The embodiment provides a multi-stage pretreatment constant-pressure balance water supply device, which is mainly used for improving water pressure stability of equipment water.

[0028] As shown in Figure 1 and Figure 6 , comprising a water storage tank 1, wherein the water storage tank 1 is provided with a water supplement port 10 and a water discharge port 11, wherein the water supplement port 10 is located at the top of the water storage tank 1; the water discharge port 11 is lower than the water supplement port 10, the water discharge port 11 is connected with a device water inlet, and a plurality of interlaced turbulence plates 12 are arranged in the inner cavity of the water storage tank 1, wherein the turbulence plates 12 are installed between the water supplement port 10 and the water discharge port 11, so as to reduce the fluctuation of the water surface caused by water entering the inner cavity of the water storage tank 1, thereby reducing the influence on the water pressure discharged by the water discharge port 11.

[0029] As shown in Figure 1 , further comprising an automatic water supplement valve 2, the water outlet end of the automatic water supplement valve 2 is connected with the water supplement port 10 through a water pipe, the water pipe between the automatic water supplement valve 2 and the water supplement port 10 is provided with an energy accumulator 4 and a flow monitoring sensor 5, and the water inlet end of the automatic water supplement valve 2 is provided with a water pump 3, comprising a processor electrically connected with the flow monitoring sensor 5 and the water pump 3.

[0030] It is worth mentioning that the water in the cavity of the water storage tank 1 is in a full state, at this time the pressure of the cavity of the water storage tank 1 is consistent with the pressure of the accumulator 4, and the automatic water replenishment valve 2 is in a closed state; when the equipment starts to use water, in the case that the automatic water replenishment valve 2 does not open in time for water replenishment, the water in the water storage tank 1 flows to the equipment, causing the water in the water storage tank 1 to decrease, at this time the pressure in the water storage tank 1 is prone to change; since the accumulator 4 is installed between the automatic water replenishment valve 2 and the water replenishment opening 10, at this time the accumulator 4 replenishes water to the water storage tank 1 for a short time and maintains the pressure in the water storage tank 1, thereby ensuring the stability of the water pressure for the equipment to use water.

[0031] In the process of opening the automatic water replenishment valve 2, at this time the flow monitoring sensor 5 monitors the signal of water flowing in the water pipe, and then transmits the signal of the flow monitoring sensor 5 to the processor, and then uses the processor to control the water pump 3 to start in time to prepare for water supply, when the automatic water replenishment valve 2 is opened, the water pump 3 can be used to continuously supply water to the water storage tank 1, and the use of the accumulator 4 can also maintain the stability of the water pressure and absorb the energy fluctuation generated in the process of water supply, when the equipment stops using water, the water pump 3 continues to supply water and maintains the pressure of the accumulator 4 to the pressure at the time of adjustment, when the pressure of the accumulator 4 reaches the specified value, at this time the automatic water replenishment valve 2 is closed.

[0032] It is worth mentioning that the flow monitoring sensor 5 is installed between the accumulator 4 and the water replenishment opening 10, which improves the sensitivity of the flow monitoring sensor 5 to monitor the water replenishment of the accumulator 4 to the water storage tank 1.

[0033] In the process of water replenishment of the water pump 3 and the accumulator 4 to the water storage tank 1, water flows from the water replenishment opening 10 to the water outlet 11, which gradually bypasses the turbulence plate 12, reducing the fluctuation influence in the process of water flow.

[0034] The water replenishment opening 10 is higher than the water outlet 11, according to the principle of the communicating vessel, the liquid level height above the water outlet 11 is maintained at a certain value, thereby ensuring the stability of the pressure at the water outlet 11, and reducing the influence of the change of the liquid level; at this time the liquid level difference between the water replenishment opening 10 and the water outlet 11 is used for the accumulator 4 to replenish water to the water storage tank 1, to cope with the opening delay of the automatic water replenishment valve 2, and the influence of the water pressure fluctuation caused by the speed adjustment of the water pump 3.

[0035] In order to provide clean water source for the accumulator 4 and the water storage tank 1, in the embodiment, as shown in Figure 1 , a filter 8 is installed between the water pump 3 and the automatic water replenishment valve 2, as shown in Figure 7 , the filter 8 is internally provided with a filter core 803 for cleaning impurities in water, wherein a water inlet 801 of the filter 8 is connected with a water outlet end of the water pump 3, and a water outlet 802 of the filter 8 is connected with a water inlet end of the automatic water replenishment valve 2.

[0036] In this process, the impurities in the water are treated by the filter 8, thereby improving the quality of the water.

[0037] As the filter 8 is used for a long time, the filter core 803 in the filter 8 is easily blocked by impurities, thereby affecting the filtering speed of the water source, and thus the filter core 803 of the filter 8 needs to be cleaned regularly. In a conventional case, the filter 8 needs to be disassembled, and thus the water pressure of the water storage tank 1 is easily changed.

[0038] Therefore, in the embodiment, as shown in Figure 1 the water outlet 802 of the filter 8 is connected with the water inlet end of the automatic water replenishing valve 2 through a stop valve 6. When the filter 8 needs to be treated, the stop valve 6 can be closed, thereby solving the problem that the water pressure of the water storage tank 1 is changed during the cleaning process of the filter 8.

[0039] In order to solve the problem that the filter 8 is disassembled for cleaning, in the embodiment, as shown in Figure 1 the filter 8 is provided with two groups and is arranged in parallel. The water inlet end 801 of each group of the filter 8 is provided with a three-way ball valve 7. The water outlet 802 of two filters 8 is connected and connected with the stop valve 6. The water inlet end 801 of the two filters 8 can be connected through the three-way ball valve 7 and connected with the water outlet end of the water pump 3.

[0040] It is worth noting that, as shown in Figure 5 the three-way ball valve 7 adopts an L-shaped valve core. Specifically, the three-way ball valve 7 includes a ball valve inlet 701, a ball valve first outlet 702 and a ball valve second outlet 703. The ball valve inlet 701, the ball valve first outlet 702 and the ball valve second outlet 703 are provided with a valve core 704. The valve core 704 is provided with an L-shaped channel 7041. The L-shaped channel 7041 is used to connect the ball valve inlet 701 and the ball valve first outlet 702, or connect the ball valve first outlet 702 and the ball valve second outlet 703. The ball valve inlet 701 of the two three-way ball valves 7 is connected with the water outlet end of the water pump 3. The ball valve first outlet 702 of the three-way ball valve 7 is connected with the water inlet end 801 of the filter 8. The ball valve second outlet 703 of the two three-way ball valves 7 is connected with the blowdown pipe 100 and inserted into the blowdown port.

[0041] In a conventional case, the two filters 8 can be used at the same time. As shown in Figure 1 the ball valve inlet 701 and the ball valve first outlet 702 of the two three-way ball valves 7 are connected, and the stop valve 6 is opened. At this time, the water of the water outlet end of the water pump 3 is branched to the two filters 8 for filtering treatment, and then gathered in front of the stop valve 6. Finally, clean water source can be supplied to the water storage tank 1 through the automatic water replenishing valve 2. At this time, the two filters 8 are used at the same time, which can be used for the case that a large amount of water is used by the equipment, and can provide enough clean water source for the equipment.

[0042] Since in this embodiment, two three-way ball valves 7 and two filters 8 are provided and are arranged in parallel, the three-way ball valves 7 and the filter 8 are defined separately here, as shown in FIG. Figure 2 and Figure 3 As shown, the three-way ball valve 7 includes a first three-way ball valve 71 and a second three-way ball valve 72 , and the filter 8 includes a first filter 81 and a second filter 82 , wherein the first three-way ball valve 71 is connected to the first filter 81 , and the second three-way ball valve 72 is connected to the second filter 82 .

[0043] When cleaning the filter element 803 of the second filter 82, Figure 2 As shown, at this time, the stop valve 6 is closed, the first three-way ball valve 71 realizes the connection between the ball valve inlet 701 and the first ball valve outlet 702, and the second three-way ball valve 72 realizes the connection between the ball valve first outlet 702 and the ball valve second outlet 703. At this time, the water pump 3 supplies water to the first filter 81 through the first three-way ball valve 71. The water is processed by the filter element 803 of the first filter 81 to filter out impurities in the water, and then enters from the water outlet 802 of the second filter 82, backflushing the filter element 803 of the second filter 82. The water flows out from the water inlet 801 of the second filter 82, and then flows to the sewage outlet through the second three-way ball valve 72 and the sewage pipe 100 to clean the filter element 803 in the second filter 82.

[0044] When cleaning the filter element 803 of the first filter 81, Figure 3 As shown, at this time, the stop valve 6 is closed, the second three-way ball valve 72 realizes the communication between the ball valve inlet 701 and the first ball valve outlet 702, and the first three-way ball valve 71 realizes the communication between the first ball valve outlet 702 and the second ball valve outlet 703. At this time, the water pump 3 sends water to the second filter 82 through the second three-way ball valve 72 and passes through the filter element 803. At this time, the impurities in the water are filtered, and then the water enters the first filter 81 through the water outlet 802 of the first filter 81, and then is discharged from the water inlet 801 of the first filter 81. At this time, the impurities on the filter element 803 of the first filter 81 are taken out, and the first filter 81 is cleaned. The discharged impurities flow into the drain pipe 100 through the valve core 704 of the first three-way ball valve 71, and then are discharged to the drain outlet, so as to clean the first filter 81.

[0045] If the water consumption of the equipment is small, one of the filters 8 can be used alone. In this embodiment, Figure 4 As shown, valves 9 are installed at the water outlet 802 of the filter 8, wherein the valve 9 behind the water outlet 802 of the first filter 81 is the first valve 91, and the valve 9 behind the water outlet 802 of the second filter 82 is the second valve 92; Here, the case of using the second filter 82 alone to filter the water quality can be referred toFigure 4 As shown, at this time, the first valve 91 can be closed, and the L-shaped channel 7041 of the first three-way ball valve 71 is used to connect the ball valve first outlet 702 and the ball valve second outlet 703, at this time, the water in the water pump 3 can stop supplying the first filter 81, and the water in the water pump 3 can only flow to the automatic water replenishing valve 2 through the second three-way ball valve 72, the second filter 82 and the stop valve 6, and then supply the water storage tank 1.

[0046] Alternatively, the first valve 91 is closed, and the L-shaped channel 7041 of the first three-way ball valve 71 is used to connect the ball valve inlet 701 and the ball valve first outlet 702, at this time, the water in the water pump 3 can enter the first filter 81 through the first three-way ball valve 71, but the water flow in this branch is blocked by the first valve 91, so that the water flow of the water pump 3 can only supply the water storage tank 1 through the branch in which the second filter 82 is located, so as to realize the small flow water supply condition of the device.

[0047] When the device is in the small flow water supply condition, the first filter 81 and the second filter 82 can be alternately used, so as to prolong the service life of the water supply device.

[0048] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
