Description

Technical Field

[0001] The present invention relates to the technical field of pressurization equipment, and particularly to a single-pipe water storage pressurization device and system. Background Art

[0002] The topological structure of the water pipe for daily water use is as Figure 1 shown. The outdoor water supply pipe directly enters each indoor water use point after passing through the water meter. If there are frequent water outages or insufficient water pressure in the tap water, users generally adopt Figure 2 the topological structure shown, and increase a "pressure pump" and a "water storage tank" (hereinafter referred to as the "traditional pressurization device") between the outdoor main water pipe and the indoor main water pipe to increase pressure and cope with water outages. This is also the way adopted by nearly 100% of the cases in reality. However, through the analysis of Figure 2 the topological structure, it can be found that this traditional pressurization device must be connected in series in the middle of the outdoor and indoor main water pipe lines. This method is applicable to the indoor main water pipe joints that have been reserved during decoration. However, if this point is not considered during decoration, and the indoor main water pipe joints are buried in the wall and a tee joint is used in the wall to connect the indoor main water pipe to each indoor water use point, as Figure 3 shown, then it is impossible to use Figure 2 the traditional pressurization device shown for improvement. Moreover, through the observation of Figure 2 , if the traditional pressurization device is equipped with a water storage tank, the water tank must be placed at a high place to form a water level difference in order to realize water use, which is very difficult to achieve in urban high-rise housing.

[0003] In summary, the traditional pressurization device shown in Figure 2 cannot be used in the environments of urban high-rise buildings and when the indoor main water pipe joints are buried in the wall during decoration. China's urbanization process has developed rapidly for decades. Due to factors such as aging water pipes, pipeline siltation, ground settlement causing water pipe rupture, and aging of the water supply system in the water area in many communities, it is difficult for high-rise buildings to use water. Using the maintenance fund for maintenance often requires a large investment and a long cycle, and cannot solve the urgent needs of users. And due to the reasons mentioned above, it is very difficult for many users to use the traditional pressurization device to improve the water use situation.

[0004] Therefore, there is an urgent need for a single-pipe water storage pressurization device and system to improve the above problems. Summary of the Invention

[0051] As Figure 1 shown, the present invention provides a single-pipe water storage and pressurization device for indoor water pressurization, which includes a water storage and pressurization assembly 2 for being installed on the water outlet side of the indoor water main pipe 12. Wherein, the water inlet end of the water main pipe 12 is communicated with the water outlet end of the outdoor water inlet main pipe 11, and at least two branch water pipes 4 arranged in parallel are communicated with the water outlet side of the water main pipe 12; the water storage and pressurization assembly 2 is arranged on any one of the branch water pipes 4 for storing the water inlet of the branch water pipe 4, and for cooperating with a one-way check valve 3 installed on the water outlet side of the water inlet main pipe 11 to pressurize the stored water through the branch water pipe 4 and output it through the branch water pipe 4 to the remaining branch water pipes 4 for water supply.

When in use, only one water pipe joint needs to be connected to any one of the branch water pipes 4 to any water use point in the whole house, such as the faucet of the balcony laundry pool, the faucet in the bathroom, the faucet in the kitchen, etc., and then the remaining branch water pipes 4 can be supplied with water, realizing single-pipe water storage and pressurization.

[0055] In still some other specific embodiments, as Figure 5 shown, the water storage and pressurization assembly 2 further includes a water quality filter 212; the water inlet end of the water storage tank 21 is connected to the water outlet end of the booster pump 22 through the water quality filter 212, and the water quality filter 212 is located on the second water pipe 28 between the water storage tank 21 and the first normally open solenoid valve.

[0056] In some embodiments, as Figure 5 shown, the water storage and pressurization assembly 2 further includes a water pressure sensor 213; the water pressure sensor 213 is connected to the connection point through a fourth water pipe 210 to detect the water pressure; the water pressure sensor 213 is electrically connected to the controller 211.

[0057] In some other embodiments, as Figure 5 shown, the water storage and pressurization assembly 2 further includes a water level sensor 214; the controller 211 is electrically connected to the water storage tank 21 through the water level sensor 214 to detect the water level of the water storage tank 21.

[0058] In some embodiments, as Figure 5 shown, the controller 211 includes a single-chip microcomputer, a corresponding human-machine operation interface, and corresponding input and output interfaces.

[0059] For ease of understanding, in this embodiment, the specific implementation process is further elaborated in combination with a specific application scenario system:

[0060] As Figure 4 shown, when using the water storage and pressurization device, a "one-way check valve 3" needs to be installed at the water meter inlet. The function of this valve is that tap water can only enter from the outdoors into the indoors, and cannot flow out from the indoors to the outdoors. Generally, this valve is default installed in the household tap water pipeline. If not installed, this valve needs to be installed when using this system.

[0061] The composition of the single-pipe water storage and pressurization device is as Figure 5 shown. It consists of 2 normally open solenoid valves (the first normally open solenoid valve 23 and the second normally open solenoid valve 24), 2 normally closed solenoid valves (the first normally closed solenoid valve 25 and the second normally closed solenoid valve 26), 1 booster pump 22, 1 water quality filter 212, 1 water storage tank 21, 1 water pressure sensor 213, 1 water level sensor 214, and 1 controller 211.

[0062] The first normally open solenoid valve 23 and the second normally open solenoid valve 24: Usually, the internal waterway switch is on, and when the coil is energized, the internal waterway is disconnected;

[0063] The first normally closed solenoid valve 25 and the second normally closed solenoid valve 26: Usually, the internal waterway switch is off, and when the coil is energized, the internal waterway is connected;

[0064] The booster pump 22: Responsible for pressurizing tap water into the water storage tank 21, or pressurizing the water in the water storage tank 21 to the whole-house water usage points;

[0065] The water storage tank 21: Used for storing water and is used during the whole-house pressurization;

[0066] The water pressure sensor 213: Monitors the water pressure in the indoor water pipe;

[0067] The water level sensor 214: Monitors the water level in the water storage tank 21;

[0068] The controller 211: There is a single-chip microcomputer program control inside, equipped with a human-machine operation interface, and has corresponding input and output interfaces to implement the control logic of the entire system;

[0069] Basic working principle

[0070] As Figure 5 and Figure 6As shown, it is a connection diagram of all components. The blue line segments represent the water pipes and water circuits, and the red line segments represent the electric control circuits. The entire system has two working states and three working modes. The working states are pressurized water storage and pressurized water discharge, and the working modes are manual, automatic, and energy-saving.

[0071] Working State

[0072] Pressurized Water Storage: The controller 211 controls all 4 solenoid valves to be powered off. At this time, the internal water circuit switch of the solenoid valve is in the Figure Five default state shown. Then the entire working water circuit is as follows: The municipal tap water from the indoor water pipe passes through "the second normally open solenoid valve 24 -> the inlet of the booster pump 22 -> the outlet of the booster pump 22 -> the first normally open solenoid valve 23 -> the water quality filter 212 -> the inlet of the water storage tank 21". The system is in the pressurized water storage state. When the controller 211 detects through the water level sensor 214 that the water level in the water storage tank 21 reaches the requirement, it stops the booster pump 22 from working, and at the same time powers on the second normally open solenoid valve 24 or the first normally open solenoid valve 23 to cut off the inlet water circuit and stop the water inlet.

[0073] Pressurized Water Discharge: The controller 211 controls all 4 solenoid valves to be powered on. At this time, the internal water circuit switch of the solenoid valve is in the Figure Six state shown. Then the entire working water circuit is as follows: "The water outlet of the water storage tank 21 -> the first normally closed solenoid valve 25 -> the inlet of the booster pump 22 -> the outlet of the booster pump 22 -> the second normally closed solenoid valve 26 -> the indoor water pipe". The system is in the pressurized water discharge state. At this time, each water-using point indoors will obtain the water pressurized from the water storage tank 21. Moreover, due to the addition of the "one-way check valve 3", this water will not flow outdoors, ensuring the indoor water use. At the same time, because it adopts the form of pumping and pressurizing, the water storage tank 21 does not need to be placed at a high position to be used normally.

[0074] Working Mode

[0075] Manual: That is, through the human-machine interaction operation buttons on the controller 211, manually achieve the working states of pressurized water storage or pressurized water discharge;

[0076] Automatic: In this mode, the controller 211 can automatically switch the working state according to the preset time. For example, when the water pressure is normal during the day, it works in the pressurized water storage state, and when the water pressure is abnormal during the peak water use at night, it works in the pressurized water discharge state. Or the controller 211 can also automatically judge whether it is necessary to pressurize and store water or pressurize and discharge water according to the signals of the water pressure sensor 213 and the water level sensor 214;

[0077] Energy saving: The time of the controller 211 can be preset at night every day. In this mode, the water circuit is default in the "water storage" state, but the booster pump 22 does not work, without consuming electric energy and generating noise. The tap water pressure is used to supply water to the water storage tank 21, so as to achieve the purpose of energy saving and practicality.

[0078] Based on the above water storage and boosting device, the present invention further provides a water storage and boosting system, including the above water storage and boosting device, a water inlet main pipe 11, a water use main pipe 12 and a one-way check valve 3; the water inlet end of the water use main pipe 12 is connected to the water outlet end of the outdoor water inlet main pipe 11, and at least two branch water pipes 4 arranged in parallel are connected to the water outlet side of the water use main pipe 12; the one-way check valve 3 is installed on the water outlet side of the water inlet main pipe 11, and the water storage and boosting assembly 2 of the device is arranged on any one of the branch water pipes 4 for storing the water inlet of the branch water pipe 4 and for cooperating with the one-way check valve 3 to boost the stored water through the branch water pipe 4 and output it to the remaining branch water pipes 4 for water supply. Different from the traditional boosting device that needs to be connected in series between the water inlet main pipe 11 and the water use main pipe 12, the method of parallel connection of water pipes is adopted, and the water storage and boosting device and the one-way check valve 3 cooperate to achieve single-pipe boosting, with extremely low requirements for the layout of pipelines, and basically all pipeline forms can be installed, with a wide range of uses and low pipeline costs.
