Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water supply and drainage, in particular to the technical field of water supply equipment using water, and more particularly to the technical field of high-lift water supply device systems requiring multi-stage pressurization, and specifically to a regulating and storing pressurization system. BACKGROUND

[0002] The regulating and storing pressurization device is mainly applied to secondary water supply and is a typical secondary water supply equipment. In order to fully understand the technical problems solved by the present application, the technical effects and social benefits generated by the present application, and the differences from the existing secondary water supply equipment, first of all, the concept of secondary water supply equipment needs to be clearly understood, and secondly, the mode and shortcomings of the existing secondary water supply equipment need to be understood.

[0003] Concept of secondary water supply equipment: the design pressure of municipal water supply pipe network is about 4.0 Kg, and the direct water supply pressure can only meet the daily water demand of floors below 7-8. The actual water supply pressure of existing buildings is far beyond the design pressure of municipal water supply, so secondary water supply is needed, and various types of secondary water supply equipment have emerged. The application of secondary water supply mainly has the following aspects: first, high-rise buildings must be subjected to secondary pressurized water supply, otherwise water cannot reach higher floors; second, even if the floor is lower than 8, but the places with high water supply guarantee degree or large water consumption, such as public water places like schools, hospitals, and hotels, must be subjected to secondary pressurized water supply.

[0004] Secondary water supply facilities are usually built in the negative two or negative three floor life water pump house during house construction. Secondary water supply equipment is mainly divided into two types: one is non-negative pressure (tank type pressure) water supply equipment, and the other is tank type water supply equipment with stainless steel life water tank. It is suitable for water supply areas with low water pipe network pressure, such as the end of water pipe network or buildings with high terrain; places with large water consumption or high water guarantee degree: such as public places like schools, hotels, and hospitals. For water supply systems, the most important thing is stability, which needs to ensure that the secondary water supply system remains in good working condition for 365 days and 24 hours, which puts high requirements on secondary water supply equipment; however, the existing secondary water supply equipment still needs to be stopped for repair due to pump failure, pipeline leakage, valve failure, etc.; and the cleaning of the water storage tank / water tank needs to be stopped regularly or irregularly to solve the cleaning or failure problems. After the secondary water supply equipment is stopped, all water-using ends will be out of water, which seriously affects the water-using experience. SUMMARY

[0005] In order to solve one of the many problems existing in the existing secondary water supply equipment as described in the background art, the application provides a regulating and storing pressurizing system for replacing the existing secondary water supply equipment to meet the requirements of cleaning without stopping and repairing without stopping, and to minimize or even eliminate the water stop problem caused by failure or cleaning.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the application is:

[0007] A regulating and storing pressurizing system, comprising a water inlet unit, a pressurizing and storing unit and a water outlet unit connected in sequence, the pressurizing and storing unit comprising a water inlet main pipe and a water outlet main pipe in sealed communication with the water inlet unit and the water outlet unit respectively, the water inlet main pipe being connected with at least one regulating and storing pipe for storing water, at least one pressurizing mechanism being installed in sealed manner on any of the regulating and storing pipes for pressurizing the water in the regulating and storing pipe and delivering it to the water outlet main pipe, and a controller being electrically connected with the pressurizing mechanism for controlling the pressurizing mechanism to execute / stop pressurizing.

[0008] Working principle:

[0009] Tap water from the municipal pipe network first enters the water inlet unit, which performs simple filtration on the tap water and then sends it to the pressurizing and storing unit, which pressurizes the tap water with an initial pressure, such as kg-kg, to a preset water supply pressure, such as kg-kg, and then sends it to the water outlet unit to the water outlet unit, such as a hospital, a hotel, a school, a family, a factory, etc. The pressurizing mechanism and the regulating and storing pipe form an integrated structure, avoiding the problem of separate space occupation of the existing pressurizing pump pipe network and water storage tank. This structural improvement has two beneficial effects:

[0010] First, under the same pressurizing power and water delivery flow rate, the application eliminates the space occupation of external pump pipe network and unit compared with the prior art, which can greatly save space.

[0011] Secondly, since the connecting pipe network between the pressurizing mechanism and the regulating and storing pipe is omitted, a large number of flange connection joints are reduced, and the probability of leakage failure of the entire water supply equipment caused by joint sealing problems is reduced.

[0012] As the simplest pressurized water supply scheme of the present application, preferably, a plurality of pressurizing mechanisms are installed in the regulating and storage pipe, the water inlet end of any pressurizing mechanism is arranged near the bottom of the regulating and storage pipe, the water outlet end of any pressurizing mechanism is connected to the water outlet main pipe through a manifold group with check valves, and it is worth noting that a valve that can be independently closed is installed on the manifold group for the convenience of subsequent maintenance, which is normally in the open state and in the closed state in emergency or maintenance.

[0013] On the basis of the above, the present application further provides another preferred scheme of pressurized water supply layout, the water outlet main pipe has a plurality of roots, and any of the water outlet main pipes is connected to a plurality of pressurizing mechanisms through a manifold group. This scheme has a plurality of water outlet main pipes with consistent or inconsistent design pressures, which respectively supply water to a plurality of different water use areas. Since any water outlet main pipe is pressurized by a plurality of parallel working pressurizing mechanisms and then concentrated in the water outlet main pipe through a return pipe group, the plurality of pressurizing mechanisms connected to the same water outlet main pipe back up each other and can work simultaneously or stop one or more pressurizing mechanisms. Therefore, compared with the traditional multi-backup-one and multi-backup-many methods, this method is more flexible, the use frequency and time of each pressurizing mechanism are more balanced, and the failure caused by excessive use or excessive idling of equipment is avoided.

[0014] The present application further provides another preferred scheme of pressurized water supply layout, the regulating and storage pipe has a plurality of, the water inlet main pipe is respectively connected to any closed flow guide pipe through a shunt pipe group; the water outlet main pipe has a plurality of roots, and any water outlet main pipe is respectively connected to the pressurizing mechanism arranged in any regulating and storage pipe through a manifold group. The biggest advantage of this method is strong storage capacity, high stability and sustainability, timely failure or regular cleaning without shutdown, fault maintenance and cleaning of the regulating and storage pipe can be carried out under the premise of normal water supply, without stopping water supply, which will not affect the normal use of the water use end. This is the most obvious and essential difference from the prior art.

[0015] In order to further enhance the practicality of the present application and meet the water supply demand and continuity to the greatest extent in extreme cases, in the above scheme, an emergency valve for communication or shutoff is arranged between any two regulating and storage pipes, and the two ends of the emergency valve are connected to the bottom or the position near the bottom of the regulating and storage pipe.

[0016] In order to further realize precise control and reduce energy consumption of the equipment, preferably, a pressure sensor for sending pressure values to the controller is arranged on the water outlet unit or the water outlet main pipe.

[0017] Further preferably, a liquid level sensor for reading the actual water level in the surge tank and directly or indirectly controlling the start / stop of the pressurization of any pressurization mechanism installed in the corresponding surge tank is arranged in the surge tank.

[0018] Preferably, the pressurization mechanism comprises a sleeve for installing a submersible pump, the top of the sleeve is provided with a negative pressure prevention valve communicating with the sleeve, the bottom of the sleeve is installed near the bottom of the surge tank, and the sleeve is detachably and airtightly connected with the surge tank.

[0019] When the water outlet end of the submersible pump is directly communicated with the water outlet main pipe through the manifold group, the water inlet end of the submersible pump is arranged at any position of the sleeve; when the water outlet end of the submersible pump is not directly communicated with the manifold group, the water inlet end of the submersible pump is communicated with the surge tank through a third anti-backflow device arranged at the bottom of the sleeve.

[0020] Preferably, the water inlet unit comprises a water inlet main valve, a first anti-backflow device and a filter which are connected in sequence and airtightly along the water flow direction and communicated with the municipal water source; the water outlet unit comprises a pressure sensor, a flow meter, an air tank and a water outlet main valve which are connected in sequence and communicated along the water flow direction and connected with the water outlet main pipe.

[0021] Preferably, the installation assembly for fixedly installing the pressurization and surge unit comprises a base which is adapted to the shape of the surge tank and used for supporting the surge tank, and a plurality of clamps which are detachably connected with the base and used for fixing the surge tank.

[0022] Advantages:

[0023] 1. In the structure of the present application, the pressurization mechanism and the surge tank are combined, the complex pump and pump pipe network of the existing secondary water supply equipment is omitted, the probability of system leakage failure is reduced, the equipment space occupation is reduced, at the same time, the equipment is simple to assemble, can be installed underground and in a machine room, and can adapt to various application scenarios.

[0024] 2. The plurality of pressurization mechanisms of the present application are backup for the same water outlet main pipe for pressurized water supply, and can realize one-to-many, many-to-one, full backup and full pressurization mode switching according to different water consumption in the same water consumption area, so as to maximize the effective utilization rate of the equipment and minimize the idle rate of the equipment.

[0025] 3、The application can independently adjust and store water among multiple storage pipes, and under normal circumstances, they do not affect each other, can independently supply, so that the whole system can realize non-stop maintenance and cleaning, and the continuity of water supply is ensured to the greatest extent, and the needs of regular maintenance and cleaning of the equipment are effectively compatible, so that the equipment is always in good condition, and the probability of equipment downtime caused by sudden failure is reduced.

[0044] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] The present embodiment provides a regulating and storing pressurization system, and in the present embodiment, a one-area multi-pipe layout is taken as an example for detailed description, which is specifically shown in the accompanying drawings of the specification. Figures 1-3 , and Figure 8 The "one area" in the one-area multi-pipe refers to the same high-pressure water pipe shared by multiple water-using areas under the same water supply pressure, i.e. the water outlet main pipe 26 in the present embodiment. The "multi-pipe" refers to the water source corresponding to the water outlet main pipe 26 for centralized water supply to the water-using area, which is collected from multiple regulating and storing pipes 24. The layout method is simply referred to as one-area multi-pipe layout in the present application. The regulating and storing pressurization system provided in the present embodiment is described as one-area three-pipe, of course, according to the technical solution disclosed in the present embodiment, one-area two-pipe, one-area four-pipe, one-area five-pipe, one-area ten-pipe, etc. can be arranged according to the same connection method, at the same time, no creative labor is required, and the solution provided in the present embodiment can be completed completely. The more regulating and storing pipes 24 corresponding to the same area, the higher the stability, the stronger the ability to ensure continuous operation, and the greater the water demand that can be met. The impact of partial equipment failure on the overall regulating and storing pressurization system is smaller. When the regulating and storing pipes 24 are equipped with enough, partial equipment failure will hardly affect normal water supply. The biggest advantage of the solution of the present embodiment is that each regulating and storing pipe 24 can cooperate with and be independently used, and can be replaced with each other. Therefore, the solution of the present embodiment can be expanded at the initial, middle and final stages of construction, and during the expansion construction process, the current pressurization system can be completed without stopping working, which cannot be achieved by the existing secondary water supply equipment.

[0047] The specific technical scheme of the embodiment comprises a water inlet unit 1, a pressurizing and storage unit 2 and a water outlet unit 3 connected in sequence, the pressurizing and storage unit 2 comprises a water inlet main pipe 21 and a water outlet main pipe 26 in sealed communication with the water inlet unit 1 and the water outlet unit 3 respectively, the water inlet main pipe 21 is connected with at least one storage pipe 24 for storing water, at least one pressurizing mechanism 23 for pressurizing water in the storage pipe 24 and delivering the water to the water outlet main pipe 26 is installed on any storage pipe 24 in a sealed manner, and a controller is electrically connected with the pressurizing mechanism 23 for controlling the pressurizing mechanism 23 to execute / stop pressurizing. Figure 1 、 Figure 2 and Figure 8 The storage pipe 24 has three, and the installation and arrangement of the three storage pipes 24 are shown in the description. Figure 3 The water inlet main pipe 21 is connected with any flow guide pipe 28 penetrating through the storage pipe 24 through a shunt pipe group 22; the water outlet main pipe 26 has three, and any water outlet main pipe 26 is connected with the pressurizing mechanism 23 arranged in any storage pipe 24 through a flow collecting pipe group 25. The biggest advantage of this mode is that the storage capacity is strong, the stability and sustainability are high, and the machine does not need to be stopped for fault repair and cleaning of the storage pipe 24 in time, the water supply can be carried out under the premise of normal water supply, the water supply does not need to be stopped, and the normal use of the water end will not be affected, which is the most obvious and essential difference from the prior art. Further, in order to facilitate cleaning of the storage pipe 24, a larger space is needed for the cleaner to enter, therefore, the pressurizing mechanism 23 can be realized by using a detachable sealed connection structure as shown in

[0048] Working principle:

[0049] Tap water from a municipal pipe network first enters the water inlet unit 1, the water inlet unit 1 performs simple filtration on the tap water and sends the tap water into the pressurizing and storage unit 2, the pressurizing and storage unit 2 pressurizes tap water with an initial pressure, such as 4kg-5kg, to a preset water supply pressure, such as 15kg-20kg, and then sends the tap water into a water outlet unit, such as a hospital, a hotel, a school, a family, a factory, etc. through the water outlet unit 3. The pressurizing mechanism 23 and the storage pipe 24 form an integrated structure, which avoids the problem that the existing pressurizing pump pipe network and water storage tank occupy space respectively. This structural improvement has two beneficial effects:

[0050] Firstly, under the premise of the same pressurizing power and water delivery flow, the application eliminates the external pump pipe network and machine set, which can greatly save space.

[0051] Secondly, since the connecting pipe network between the pressurizing mechanism 23 and the regulating and storing pipe 24 is omitted, a large number of flange joint connections are reduced, and the probability of leakage failure of the entire water supply equipment caused by joint sealing problems is reduced.

[0052] Further, compared with the existing secondary water supply equipment, the actual water supply process of the present embodiment has more beneficial effects than the above two points. The working principle and corresponding technical effects of the present embodiment are described as follows:

[0053] During normal water supply, according to the actual water consumption, the number of the three pressurizing mechanisms 23 corresponding to the same water outlet main pipe 26 is controlled by the controller in a closed loop. The principle of closed loop control is consistent with that of the existing closed loop control, that is, the number of pressurizing mechanisms 23 working for pressure increase is determined by monitoring the difference between the pressure at the water outlet main pipe 26 and the preset water supply pressure. The monitoring of the water supply pressure can be realized by the existing pressure sensor. This part is not the improvement point of the present application. Any existing closed loop control that meets the control requirements of the present embodiment can be used. Details are not described here. In the present embodiment, when the water consumption is 0 or the water consumption is very small, the three pressurizing mechanisms 23 stop working or work intermittently. When the water consumption increases and continues, the pressure at the water outlet main pipe 26 will drop sharply. At this time, in order to keep the actual pressure equal to the preset pressure, one pressurizing mechanism 23 will work continuously to increase the pressure until the actual pressure at the water outlet main pipe 26 reaches the preset pressure. If one pressurizing mechanism 23 still cannot meet the requirements, the second pressurizing mechanism 23 will be added, and the third pressurizing mechanism 23 will be in standby state. If it still cannot meet the requirements, all three pressurizing mechanisms 23 will be added to the pressurizing state until the water consumption decreases. In this way, the three pressurizing mechanisms 23 work according to the instructions of the controller, and they are mutually backed up, without the distinction between the working pressurizing mechanism 23 and the backup pressurizing mechanism 23. Therefore, compared with the existing technology of one standby two and two standby one, the problem of excessive wear of working equipment and excessive idling of standby equipment leading to failure is overcome.

[0054] Furthermore, in the prior art, if any of the pressurizing devices or standby devices fails and needs to be repaired, the entire storage tank or water tank needs to be emptied or, according to the location of the failure, at least the water supply pipeline needs to be disconnected from the water tank, the water in the water tank needs to be depressurized, and then the repair can be performed, otherwise, the water will be sprayed under the pressure of the municipal pipeline during the removal of the device. In the embodiment, after any of the pressurizing mechanisms 23 fails, only the valve on the shunt pipe group 22 corresponding to the failed pressurizing mechanism 23 needs to be closed, and the storage tank 24 corresponding to the current failure pressurizing mechanism 23 needs to be disconnected from the shunt pipe group 22, and then normal repair can be performed. At this time, the other two storage tanks 24 and pressurizing mechanisms 23 can still work normally, ensuring that the system does not stop, and the water supply is uninterrupted, so that the system sustainability is greatly increased, and the need for repair without water interruption is met, which cannot be achieved by the prior art.

[0055] Finally, when the storage tank 24 needs to be cleaned regularly, any of the storage tanks 24 can be shut off individually, and the work of any other storage tank 24 and pressurizing mechanism 23 will not be affected, avoiding the need to send a notice to the water-using unit in advance to perform regular shutdown cleaning when cleaning the water tank or storage tank of the existing secondary water supply device, thereby causing water interruption. The embodiment can achieve gradual cleaning and continuous operation, and the water-using unit is not affected at all by water interruption, and the cleaning is implemented without awareness.

[0056] Embodiment 2

[0057] On the basis of the structure and water supply principle described in Embodiment 1, another pressurized water supply scheme is provided in the embodiment, which is described in the form of one district and one pipe layout, and details are shown in the attached drawings of the specification Figure 6As shown, the regulating tank 24 is provided with a plurality of pressurizing mechanisms 23, the water inlet end of any pressurizing mechanism 23 is arranged at a position close to the bottom of the regulating tank 24, and the water outlet end of any pressurizing mechanism 23 is communicated with the water outlet main pipe 26 through the manifold group 25 with check valve. The water inlet main pipe 21 is communicated with the regulating tank 24 through the flow guide pipe 28, and the water outlet end of the flow guide pipe 28 is arranged at a position away from the water inlet end of the pressurizing mechanism 23. The purpose of arranging the flow guide pipe 28 away from the pressurizing mechanism 23 is to keep the water in the regulating tank 24 in a flowing state, so as to avoid the water that enters the regulating tank 24 first being discharged before the water that enters the regulating tank 24 later, thereby causing "dead water" in the regulating tank 24, accelerating the deterioration of water quality in the regulating tank 24, and causing water deposition. It should be noted that as an alternative solution substantially the same as the above solution, the same purpose can be achieved by changing the installation position or length of the flow guide pipe 28; for example, if the pressurizing mechanism 23 is arranged at a position close to the left side of the regulating tank 24, the flow guide pipe 28 can be arranged at any position of the regulating tank 24, but extends to a position close to the right side of the regulating tank 24. Similarly, as a matter of common knowledge, the flow guide pipe 28 can be arranged at a position close to the right side of the regulating tank 24, thereby shortening the extension length of the flow guide pipe 28. As an extreme case, the flow guide pipe 28 can be arranged at a position opposite to the pressurizing mechanism 23, thereby making the length of the flow guide pipe 28 into the regulating tank 24 zero. In this case, the flow guide pipe 28 should be understood as an external pipe connected to the regulating tank 24 for water inlet. If there is no water distribution between the water inlet main pipe 26 and the flow guide pipe 28, they are integrated. The water inlet main pipe 26 is a section close to the municipal water source, and the flow guide pipe 28 is a section connected to the regulating tank 24. Therefore, in this application, the understanding of the flow guide pipe 28 should be based on the fact that the water inlet provided by the flow guide pipe 28 and the water inlet end of the pressurizing mechanism 23 are away from each other to achieve the flowing of water in the regulating tank 24, and the installation position and length of the flow guide pipe 28 should not be mechanically considered as the essential factor of the solution. The above solution is more suitable for a single design pressure user group, and a unified water supply pipe network is used to achieve centralized pressurized water supply. For example, small hospitals, kindergartens, schools or single low-rise building water supply and other application scenarios. This layout mode is that any one of the three zones is standby for each other, and any one of the regulating tanks 24 or the pressurizing mechanisms corresponding to the zone can be shut down for cleaning, cleaning, sterilization and other operations. The other two zones can supply water without interruption, and the influence is complementary. The same can achieve non-perception water supply, and the other working principles and embodiments 1 are the same, which will not be described here.

[0058] Embodiment 3:

[0059] On the basis of the structure and water supply principle described in Embodiment 1, this embodiment provides another preferred solution of pressurized water supply layout, which is taken as an example of multi-zone one-pipe for illustration, and details are shown in the following table. Figure 7As shown, the water outlet main pipe 26 has a plurality of pressurizing mechanisms 23 connected through the header pipe group 25. The present scheme has a plurality of water outlet main pipes 26 with consistent or inconsistent design pressure, which respectively supply water to a plurality of different water consumption areas. Since any water outlet main pipe 26 is pressurized by a plurality of parallel working pressurizing mechanisms 23 and then concentrated in the water outlet main pipe 26 through the return pipe group 25, the plurality of pressurizing mechanisms 23 connected to the same water outlet main pipe 26 are backed up to each other, and can work simultaneously or stop one or more pressurizing mechanisms 23. Compared with the traditional multi-backup one and multi-backup mode, the present scheme is more flexible, and the use frequency and time of each pressurizing mechanism 23 are more balanced, avoiding failures caused by overuse or over-idling of equipment. The present scheme also uses the multi-area backup mode for water supply. The only situation that needs to stop water supply is to clean and disinfect the shared surge tank 24, which requires a short shutdown and suspension of water supply. However, it should be noted that the present embodiment is generally applied to large or super-large surge tanks 24. In this case, the water consumption is regular, and there is enough time to clean the surge tank 24, so this problem does not exist in practical application.

[0060] Embodiment 4:

[0061] In order to further enhance the practicability of the present application, the present embodiment is further optimized for embodiments 1 and 2, and maximizes the satisfaction of water supply demand and continuity in extreme cases, for example, when the municipal pipe network suddenly stops supplying tap water, and at the same time, one or more pressurizing mechanisms 23 in a certain surge tank 24 fail, causing the water resources in the surge tank 24 to be unavailable. In view of this emergency, the present embodiment is provided with an emergency valve for communication or shutoff between any two surge tanks 24 in the schemes of embodiments 1 and 2, and the two ends of the emergency valve are in communication with the bottom or the position close to the bottom of the surge tank 24. Thus, the mode switching between a multi-pipe in a region and a single pipe in a multi-region is realized. The advantage of this is that it can fully utilize the water storage in the surge tank 24 in the case of simultaneous water stop and equipment failure, and it can also empty any surge tank 24 for separate processing in the case of emergency repair, realizing mode transformation and inheriting all the advantages of the two modes for different emergency situations. It should be noted that since the emergency valve is installed at the bottom of the surge tank 24, if the system is installed in a buried manner, the valve control rod of the emergency valve needs to be lengthened until it extends to the ground to facilitate operation.

[0062] Embodiment 5:

[0063] In order to further realize precise control and reduce energy consumption of the equipment, the embodiment is further optimized on the basis of any of the above embodiments, and specifically further combined with the drawings of the specification Figures 1-5 The pressure sensor 33 is arranged on the water outlet unit 3 or the water outlet main pipe 26 and used to send the pressure value to the controller.

[0064] In the embodiment, the liquid level sensor 234 is arranged in the regulating and storage pipe 24 and used to read the actual water level in the regulating and storage pipe 24 and directly or indirectly control the installation of the pressurizing mechanism 23 in any regulating and storage pipe 24 to execute or stop pressurizing. The top of the regulating and storage pipe 24 is provided with a negative pressure prevention valve 235 in communication with the regulating and storage pipe 24. The pressurizing mechanism 23 comprises a sleeve 233 for installing a submersible pump 236. The bottom of the sleeve 233 is arranged close to the bottom of the regulating and storage pipe 24. The sleeve 233 is detachably and airtightly connected with the regulating and storage pipe 24.

[0065] When the water outlet end of the submersible pump 236 is directly communicated with the water outlet main pipe 26 through the manifold group 25, as shown in Figure 5 , the water inlet end of the submersible pump 236 is arranged at any position of the sleeve 233. When the water outlet end of the submersible pump 236 is not directly communicated with the manifold group 25, as shown in Figure 4 , the water inlet end of the submersible pump 236 is communicated with the regulating and storage pipe 24 through the third anti-backflow device 237 arranged at the bottom of the sleeve 233. By using the above two ways, as shown in Figure 4 and Figure 5 , different types of submersible pumps 236 can be satisfied. No matter where the water suction position and the water outlet position of the submersible pump 236 are located, the submersible pump 236 can be perfectly installed in the application, which greatly reduces the problems of poor system compatibility and difficult maintenance in the later period caused by matching specific accessories or free single type accessories.

[0066] Embodiment 6

[0067] The embodiment is further optimized and improved on the basis of embodiment 1, and specifically further combined with the drawings of the specification Figure 8 and Figure 9As shown, the water inlet unit 1 includes a water inlet main valve 11, a first anti-backflow device 12 and a filter 13 connected in sequence along the water flow direction and in communication with the municipal water source, the water outlet unit 3 includes a pressure sensor 33, a flow meter 32, an air tank and a water outlet main valve 31 connected in sequence along the water flow direction and in communication with the water outlet main pipe 26, and the water inlet main valve 11 is electrically connected to the controller. Meanwhile, as another alternative of the embodiment 4, the stored water resources in the plurality of regulating and storage tanks 24 can be fully utilized under the premise of water stoppage, so as to maximize the resource utilization and overcome the problem that the water resources in the corresponding regulating and storage tank 24 cannot be used due to the sudden equipment failure under the water stoppage. When the water stoppage occurs and all the pressurizing mechanisms 23 in a certain regulating and storage tank 24 suddenly fail to work normally, the water resources in the regulating and storage tank 24 cannot be utilized. At this time, the controller can be used to close the water inlet main valve 11, and the anti-negative pressure valve (235) on each normal regulating and storage tank 24 can be manually / automatically closed, so as to form the same closed space in the plurality of regulating and storage tanks 24. When the water in any regulating and storage tank 24 is reduced, the anti-negative pressure valve 235 of the regulating and storage tank 24 with the failure can introduce air into the regulating and storage tank 24, so that the siphon phenomenon can be formed between the plurality of regulating and storage tanks 24, so that the water resources in the regulating and storage tank 24 with the failure are used up first. It should be noted that the existing anti-negative pressure valve 235 has mechanical type, such as the ball float structure, and automatic type, such as the electromagnetic control structure, so that the opening and closing of the anti-negative pressure valve 235 can be manual or automatic, which is a known technology in the art and is not the improvement of the embodiment, and will not be described in detail here.

[0068] In the embodiment, the installation assembly 27 for fixedly installing the pressurizing and storage unit 2 is also included, the installation assembly 27 includes a base 272 adapted to the shape of the regulating and storage tank 24 and used for supporting the regulating and storage tank 24, and a plurality of clamps 271 detachably connected to the base 272 and used for fixing the regulating and storage tank 24.

[0069] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
