Hereinafter, preferred embodiments of the present invention will be fully described with reference to the accompanying drawings.

Example 1:

the present embodiment provides a storage and pressurization system, which is described in detail by taking a one-zone multi-tube layout as an example, and specifically shown in fig. 1-3 and fig. 8 of the specification; the "one zone" in the one-zone multiple pipes refers to the same high-pressure water pipe which is shared by the water zones with the same water supply pressure, namely the water outlet main pipe 26 in the embodiment. The 'multi-pipe' is that the water source corresponding to the outlet main pipe 26 which is pointing to the water using area for centralized water supply is collected from a plurality of regulating and storing pipes 24, and the layout mode is simply referred to as a one-area multi-pipe layout mode in the application. The storage and pressurization system provided by this embodiment is described with one zone and three pipes, and of course, according to the technical solution disclosed in this embodiment, a person skilled in the art can arrange one zone with two pipes, one zone with four pipes, one zone with five pipes … … and one zone with ten pipes according to the same connection manner, and at the same time, it does not need to pay creative labor, and it can be completed completely depending on the solution provided by this embodiment. The regulation pipe 24 that same district corresponds is more its stability higher, and the guarantee capacity of continuous operation is stronger more, can satisfy bigger water consumption demand, and partial equipment trouble is just less to whole regulation pressurization system's influence, and when regulation pipe 24 was equipped with abundant, partial equipment trouble can hardly influence normal water supply. Because the scheme of the embodiment has the greatest advantage that each storage regulating pipe 24 can be mutually matched and independently used and can also be replaced, the scheme of the embodiment can be expanded at the initial stage, the middle stage, the final stage of construction and after being put into use, and the expansion can be completed without stopping the operation of the current pressurizing system in the expansion construction process, which cannot be realized by the existing secondary water supply equipment.

The concrete technical scheme that this embodiment adopted includes the unit 1 of intaking that communicates in proper order, pressurization regulation unit 2 and the unit 3 of going out water, pressurization regulation unit 2 including respectively with the female pipe 21 of intaking of the airtight intercommunication of unit 1 of intaking and the unit 3 of going out water and the female pipe 26 of going out water, the female pipe 21 of intaking at least intercommunication has a regulation pipe 24 that is used for retaining, arbitrary sealed installation has at least one to be used for pressurizeing the water in the regulation pipe 24 and carries to go out the pressure mechanism 23 of the female pipe 26 of going out water on the regulation pipe 24, and respectively with the pressure mechanism 23 electricity is connected and is used for controlling the controller that the pressure mechanism 23 carries out/stops the pressurization. The storage tube 24 has 3, and the installation and arrangement of the 3 storage tubes 24 are shown in the attached fig. 1, fig. 2 and fig. 8 of the specification. The water inlet main pipe 21 is respectively communicated with any guide pipe 28 hermetically penetrating through the storage and regulation pipe 24 through a diversion pipe group 22; the number of the outlet header pipes 26 is 3, and any one of the outlet header pipes 26 is respectively communicated with the pressurizing mechanism 23 provided in any one of the storage pipes 24 through a confluence pipe group 25. The most significant advantage of this approach is that the regulation capacity is strong, the stability and sustainability are high, the maintenance and cleaning of the regulation pipe 24 can be performed on the premise of normal water supply without stopping water supply, and the normal use of the water end is not affected, which is the most obvious and essential difference from the prior art. Further, in order to clean the storage tube 24 conveniently, a large space is needed for cleaning personnel to enter, and therefore, the pressurizing mechanism 23 may be implemented by using a detachable sealing connection structure as shown in fig. 3, specifically, a second flange 232 is provided on the storage tube 24, the pressurizing mechanism 23 is fixedly and hermetically connected with a first flange 231, and the first flange 231 and the second flange 232 are detachably and hermetically connected.

The working principle is as follows:

tap water from a municipal pipe network firstly enters a water inlet unit 1, the water inlet unit 1 simply filters the tap water and then sends the tap water into a pressurizing and regulating unit 2, and the pressurizing and regulating unit 2 pressurizes the tap water with initial pressure, such as 4kg-5kg, to preset water supply pressure, such as 15kg-20kg, and then sends the tap water into water gushing units, such as hospitals, hotels, schools, families, factories and the like, through a water outlet unit 3. The pressurizing mechanism 23 and the storage pipe 24 form an integrated structure, so that the problem that the pipe network and the water storage tank of the existing pressurizing pump machine occupy space respectively is avoided. The beneficial effects brought by the structural improvement are as follows:

firstly, on the premise of the same pressurizing power and water delivery flow, compared with the prior art, the water pump has the advantages that an external pump machine pipe network and a unit are not occupied, and the space can be greatly saved.

Secondly, because the connecting pipe network between the pressurizing mechanism 23 and the regulating and storing pipe 24 is omitted, a large number of joints connected by flanges are reduced, and the probability of leakage fault of the whole water supply equipment caused by the problem of joint sealing is reduced.

Further, taking the embodiment as an example, compared with the existing secondary water supply equipment, the practical water supply process of the embodiment has more than the above two advantages, and the following working principles and corresponding technical effects of the embodiment are set forth one by one as follows:

when normally supplying water, according to the actual water consumption how much, the quantity that three presser mechanism 23 that same female pipe of play 26 corresponds worked is by controller closed-loop control, closed-loop control's principle is unanimous with current closed-loop control, the quantity that the presser mechanism 23 that actually is used for the pressure boost works is confirmed through the pressure of monitoring the female pipe of play 26 department and the difference of predetermineeing water supply pressure promptly, water supply pressure's monitoring accessible current pressure sensor realizes, this part is not this application improvement point, adopt and satisfy in the current arbitrary closed-loop control that satisfies this embodiment control requirement can, do not detailed description here. In the present embodiment, when the amount of water used is 0 or the amount of water used is extremely small, the three pressurizing mechanisms 23 stop operating, or intermittently and alternately operate; when the water consumption is increased and continued, the pressure at the water outlet main pipe 26 is suddenly reduced, and at this time, in order to keep the actual pressure equal to the preset pressure, one pressurizing mechanism 23 is continuously operated to continuously pressurize until the actual pressure at the water outlet main pipe 26 reaches the preset pressure; if one pressing mechanism 23 still cannot work, a second pressing mechanism 23 is added, and the third pressing mechanism is in a standby state; if it is still not satisfied, the three pressurizing mechanisms 23 may be all put into the pressurized state until the amount of water used is reduced. Thus, the three pressurizing mechanisms 23 work according to the instruction of the controller, the three pressurizing mechanisms are mutually backed up, and no real working pressurizing mechanism 23 and backup pressurizing mechanism 23 are provided, so that compared with the mode of one for two and one for one in the prior art, the problem of failure caused by excessive abrasion of working equipment and excessive idle of standby equipment is solved.

Furthermore, among the prior art, if any pressurizing equipment or backup unit trouble need overhaul the time, need empty the water in whole regulation pipe or the water tank or according to the fault location, need at least with tap water pipeline and water tank disconnection, could overhaul after the water pressure release in the water tank, otherwise when equipment demolishs, can lead to the accident of running water spun under the pressure of municipal pipe network. After any one of the pressurizing mechanisms 23 in the embodiment has a fault, only the valve on the shunt tube group 22 connected with the pressurizing mechanism 23 corresponding to the fault needs to be closed, the regulating and storing tube 24 and the shunt tube group 22 corresponding to the current fault pressurizing mechanism 23 can be disconnected for normal maintenance, at the moment, the other two regulating and storing tubes 24 and the pressurizing mechanism 23 can still normally work, the system is ensured not to be stopped, and the fault is eliminated on the premise of uninterrupted water supply, so that the sustainability of the system is greatly increased, the requirement of maintenance without water stopping is met, and the problem cannot be realized in the prior art.

Finally, when the storage pipes 24 need to be cleaned regularly, any one storage pipe 24 can be turned off independently, the work of any other storage pipe 24 and the pressurizing mechanism 23 cannot be influenced, and the problem that the existing secondary water supply equipment needs to give a notice to a water consumption unit in advance to perform regular shutdown cleaning when cleaning the water tank or the storage pipes is solved, so that the water supply is stopped. The embodiment can realize gradual cleaning and continuous operation, and the unit of water consumption is not influenced by water cut at all, thereby realizing non-perception cleaning.

Example 2:

on the basis of the structure and the water supply principle described in embodiment 1, another pressurized water supply scheme is provided in this embodiment, which is described in a one-area one-pipe layout manner, as shown in fig. 6 in the specification, a plurality of pressurizing mechanisms 23 are installed in the storage regulating pipe 24, a water inlet end of any pressurizing mechanism 23 is disposed in the storage regulating pipe 24 near the bottom, a water outlet end of any pressurizing mechanism 23 is communicated with the water outlet main pipe 26 through a confluence pipe group 25 with a check valve, the water inlet main pipe 21 is communicated with the storage regulating pipe 24 through a flow guide pipe 28, and a water outlet end of the flow guide pipe 28 is disposed at a position far from the water inlet end of the pressurizing mechanism 23. The purpose of the position of the flow guide pipe 28 away from the pressurizing mechanism 23 is to keep the water entering the storage pipe 24 in a running water state all the time, so as to avoid the problems that the water entering first is not discharged yet, and the water coming later is discharged first, so that 'dead water' is caused in the storage pipe 24, the water quality in the storage pipe 24 is accelerated to deteriorate, and the water is deposited. It is to be noted that, as an alternative substantially identical to the above, the same object may be achieved by changing the installation position or length of the draft tube 28; for example, if the pressurizing mechanism 23 is installed in the storage tube 24 at a position closer to the left side, the flow guide tube 28 may be installed at any position of the storage tube 24, but may extend in the storage tube 24 to a position closer to the right side of the storage tube 24; similarly, as a general problem, the flow guide tube 28 may be directly disposed at a position close to the right side of the storage and regulation tube 24, so as to shorten the extension length of the flow guide tube 28; as an extreme case, the flow guide pipe 28 may be disposed on the opposite side of the pressurizing mechanism 23, so that the length of the flow guide pipe 28 extending into the storage pipe 24 is zero, in which case the flow guide pipe 28 should be understood as an external pipe connected to the storage pipe 24 for water intake, and if there is no flow split between the water intake main pipe 26 and the flow guide pipe 28, the two are an integral structure; the inlet manifold 26 is a section near the municipal water supply, and the conduit 28 is a section connected to the storage tube 24. In the present application, therefore, the flow conduit 28 should be understood as standing in the sense that the water inlet provided by it and the water inlet end of the pressurizing means 23 are distant from each other to achieve the water flow in the storage tube 24, and the position where it is mechanically installed, the length as a factor limiting the nature of the solution. The scheme is suitable for the use group with single design pressure, and the centralized pressurization water supply is realized through a set of unified water supply network. For example, small hospitals, kindergartens, schools, or single low-rise buildings are used for water supply. In the layout mode, three areas are mutually standby, the storage tubes 24 or the pressurizing mechanisms corresponding to any one area are in failure or need to be cleaned, sterilized and the like, and can be completely shut down, the other two areas can be supplied without interruption, the complementary influence can be realized, the non-inductive water supply can be realized, and other working principles are the same as those of the embodiment 1, and are not described herein again.

Example 3:

in addition to the structure and water supply principle described in embodiment 1, the present embodiment provides another preferred pressurized water supply layout, which is described by taking a multi-zone one-pipe as an example, and as shown in fig. 7 in detail, the outlet header 26 has a plurality of pipes, and any one of the outlet header 26 is connected to a plurality of pressurizing mechanisms 23 through a manifold group 25. The scheme is provided with a plurality of water outlet main pipes 26 with the same or different design pressures, and the water outlets for a plurality of different water areas are supplied with water in a centralized manner respectively, and any one of the water outlet main pipes 26 is pressurized by a plurality of parallel-working pressurizing mechanisms 23 and then is concentrated in the water outlet main pipe 26 through the backflow pipe group 25, so that the plurality of pressurizing mechanisms 23 communicated with the same water outlet main pipe 26 are mutually backed up, can work simultaneously or stop one or more of the pressurizing mechanisms 23, compared with the traditional method of preparing one by one, the method of preparing a plurality of pressurizing mechanisms is more flexible, the use frequency and time of each pressurizing mechanism 23 are more balanced, and the faults caused by excessive use or excessive idling of equipment are avoided. The scheme also adopts a multi-region mutual backup mode to supply water, and the only condition needing to stop supplying water is that the common regulating and storing pipe 24 needs to be shut down temporarily for cleaning and disinfection, and the water supply is stopped. However, it should be noted that the solution described in this embodiment is generally an application scenario of a large or ultra-large storage tube 24, and this situation generally has regularity in water usage, and even if the storage tube 24 needs to be cleaned by stopping the machine for a long time, a very long and sufficient time can be found for processing, so this problem does not exist in real applications.

Example 4:

in order to further enhance the utility of the present application, the present embodiment is further optimized for embodiments 1 and 2, and the requirement and continuity of water supply can be satisfied to the greatest extent in extreme cases, for example, when the tap water of the municipal pipe network is cut off suddenly, and at the same time, the pressurizing mechanism 23 in one or more of the storage pipes 24 breaks down suddenly, which results in the problem that the water resource in the storage pipe 24 cannot be utilized. For this emergency, in the solutions of embodiments 1 and 2, an emergency valve for communication or shutoff may be disposed between any two of the storage tubes 24, and two ends of the emergency valve communicate with the bottom of the storage tube 24 or a position near the bottom. Therefore, mode switching between one-zone multi-pipe mode and one-zone multi-pipe mode is achieved, the advantages that water storage inside the storage pipes 24 can be fully utilized for emergency under the condition that water cut-off and equipment faults occur simultaneously, meanwhile, any storage pipe 24 can be independently pumped out for single-row processing when emergency maintenance is needed, mode conversion is achieved, all advantages of the two modes are compatible and inherited, and different emergency situations are met. It should be noted that, because the emergency valve is installed at the bottom of the storage pipe 24, if the system is installed in a buried manner, the valve control rod of the emergency valve needs to be lengthened until the valve control rod extends to the ground, so as to facilitate the operation.

Example 5:

in order to further realize accurate control and reduce the energy consumption of the equipment, the embodiment is further optimized on any one of the above embodiments, and is specifically further shown in fig. 1 to 5 in combination with the description; and the pressure sensor 33 is arranged on the water outlet unit 3 or the water outlet main pipe 26 and used for sending pressure values to the controller.

In this embodiment, a liquid level sensor 234 is further included in the storage tube 24 for reading the actual water level in the storage tube 24 and directly or indirectly controlling the pressurization of any of the pressurization mechanisms 23 installed in the corresponding storage tube 24.
