Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Example:

[0034] Reference Figure 1-Figure 6 A pipe network superimposed water supply integrated equipment includes two groups of tap water source end pipes 1 and a water storage tank 5 connected to the tap water source end pipe 1, the outer wall of the water storage tank 5 is wrapped with a sound insulation board 4, and a tank cover is arranged on the top of the water storage tank 5, and a remote pressure gauge and an air filter device are connected to the top of the tank cover in sequence, and the air filter device is connected to the water storage tank 5 through a valve.

[0035] In this embodiment, tap water is poured into the water tank 5 through the tap water source end pipe 1, and an air filter device with a valve is provided on the top of the water tank 5 to filter and clean the outside air to prevent external dirt from entering the water tank 5 with the air and polluting the water quality. At the same time, the outer wall of the water tank 5 is wrapped with a sound insulation board 4 to minimize the noise pollution generated during the water supply process.

[0036] One end of the two groups of tap water source end pipes 1 is fixedly connected to a filter 2, one side of the filter 2 is fixedly connected to a check valve 3, one end of one group of check valves 3 is connected to a water storage tank 5, and one end of the other group of check valves 3 is fixedly connected to a first liquid level gauge 9, and one end of the first liquid level gauge 9 is connected to the bottom of the booster tank 6 through a water pipe.

[0037] In this embodiment, tap water is respectively poured into the water storage tank 5 and the boosting tank 6, and the boosting tank 6 is used to form independent air chambers and liquid chambers in the water storage tank 5, and the air chamber is connected to the air supply component, and the liquid chamber is connected to the submersible pump 7, so that the water pressure is circulated and controlled to ensure timely pressurization treatment.

[0038] It should be noted that a filter 2 is provided at one end of the tap water source pipe 1 , and the filter 2 is used to filter and clean the tap water transported into the water storage tank 5 .

[0039] The bottom of the water storage tank 5 is connected to a first drainage pipe 11, one end of the first drainage pipe 11 is connected to a water supply pipe 14, one side of the water supply pipe 14 is equidistantly connected to a household branch pipe 15, the top of the first drainage pipe 11 is connected to a booster bottle 20, and an air supply assembly is arranged between the booster bottle 20 and the booster assembly. The air supply assembly includes a bridge frame 21 connected to the bottom of the booster bottle 20, the bridge frame 21 is connected to the first drainage pipe 11, the top of the booster bottle 20 is connected to the booster tank 6 through a parallel pipe 19, an air bag 32 is arranged at the top of the booster bottle 20, a water cavity 33 is arranged below the air bag 32, and a second liquid level gauge 34 is arranged in the water cavity 33.

[0040] In this embodiment, at least three groups of booster bottles 20 are connected to the first drain pipe 11 through a bridge frame 21 and a bend pipe 22. When the first drain pipe 11 supplies tap water to the water supply pipe 14, the booster bottles 20 will be instantly filled with tap water, thereby increasing the water pressure in the first drain pipe 11 and ensuring that the supply pressure of tap water meets the demand for domestic water.

[0041] The pressurizing pipe 16 is connected with a shunt pipe 35 , the shunt pipe 35 is connected with a solenoid valve 36 , and the shunt pipe 35 is connected with the water cavity 33 , and the second liquid level meter 34 is electrically connected with the solenoid valve 36 .

[0042] Taking into account that, during the pressurization of the booster bottle 20, tap water will flow into the water supply pipe 14 as the water is supplied, and the water level in the booster bottle 20 will drop due to the difference in water flow rate, but the water pressure after the drop cannot be guaranteed. Therefore, the tap water in the pressure pipe 16 is introduced into the booster bottle 20 through the bypass pipe 35 to ensure that the water pressure in the booster bottle 20 remains sufficient.

[0043] It should be noted that a solenoid valve 36 is provided in the shunt pipe 35 , and the second liquid level gauge 34 provided in the booster bottle 20 is electrically connected to the solenoid valve 36 , thereby achieving timely replenishment of the water pressure in the booster bottle 20 .

[0044] This embodiment also includes: a submersible pump 7 is installed on a support leg 8 on one side of the inner wall of the water storage tank 5, and a booster assembly is arranged inside the water storage tank 5, and the booster assembly is connected to the submersible pump 7; the booster assembly includes a booster tank 6, and a piston plate 10 is slidably arranged inside the booster tank 6, a piston rod 27 is connected to the center position of the bottom of the piston plate 10, and a filter plate 29 is fixedly connected to the surface of the piston rod 27, a through hole 31 is opened in the filter plate 29, and a scraper 30 is arranged on the outer circle of the bottom surface of the filter plate 29, and the scraper 30 is arranged in contact with the inner wall of the booster tank 6.

[0045] In this embodiment, a piston plate 10 is arranged in the boosting tank 6, and the outer ring of the piston plate 10 and the inner wall of the boosting tank 6 are sealed and fitted. The boosting tank 6 is divided into an air chamber and a liquid chamber by the piston plate 10. Three groups of filter plates 29 are arranged in the liquid chamber. A through hole 31 is opened in the filter plate 29. After the air chamber and the air bag 32 are connected, after the air pressure is applied to the piston plate 10, the piston plate 10 drives the piston rod 27 and the filter plate 29 on the surface of the piston rod 27 to squeeze downward, and squeezes the water under high pressure toward the submersible pump 7 for secondary pressurization, thereby further ensuring the water pressure and meeting the water supply needs.

[0046] A spring 28 is provided between adjacent filter plates 29. The spring 28 is sleeved on the surface of the piston rod 27. The bottom of the booster tank 6 is connected to a second drain pipe 23. The piston rod 27 is slidably inserted into the second drain pipe 23 during vertical movement.

[0047] Since the boost tank 6 is not easy to clean, a scraper 30 is arranged around the filter plate 29. The scraper 30 fits the tank wall of the boost tank 6. Therefore, the filter plate 29 can clean the impurities on the tank wall of the boost tank 6 during the downward movement. The spring 28 is squeezed by the filter plate 29 during the downward movement, thereby ensuring the cleaning area of ​​the scraper 30. At the same time, the piston rod 27 slides in the second drain pipe 23 during the downward movement, thereby ensuring the smooth discharge of the tap water in the boost tank 6 and increasing the water flow pressure.

[0048] A suction pipe 26 is provided at the bottom of the submersible pump 7 , the second drain pipe 23 is connected to the suction pipe 26 , and a pressure valve 24 is provided at the connecting position between the second drain pipe 23 and the suction pipe 26 , and one side of the pressure valve 24 is connected to the suction pipe 26 through a tee 25 .

[0049] In this embodiment, a suction pipe 26 is provided at the bottom of the submersible pump 7, which is used to inject the tap water in the water storage tank 5 into the water supply pipe 14 under high pressure. At the same time, it is connected to the second drain pipe 23 through a tee 25. During the action of the boosting tank 6, the submersible pump 7 is used to supply water and perform secondary pressurization.

[0050] A flow guide shaft 12 is rotatably arranged in the first drainage pipe 11 , and a ring-shaped dial plate 13 is arranged on the surface of the flow guide shaft 12 . A pressurizing pipe 16 is connected to the water supply pipe 14 at the top of the submersible pump 7 , and a flow meter 17 is arranged in the pressurizing pipe 16 .

[0051] In this embodiment, the water flow in the first drain pipe 11 is used to drive the paddle 13 to rotate, thereby driving the guide shaft 12 to rotate. At least five groups of paddles 13 are arranged on the surface of the guide shaft 12. It should be noted that the paddle 13 is a thin plate with a blade, which realizes the smooth flow of tap water and prevents the water flow from being blocked due to the excessively long pipe.

[0052] In the present invention, the tap water source end pipe 1, the filter 2 and the check valve 3 are opened to inject tap water into the water storage tank 5 and the booster tank 6. The water in the water storage tank 5 is injected into the water supply pipe 14 through the first drainage pipe 11 and enters the house through the household branch pipe 15. The submersible pump 7 is started, and the tap water enters the water supply pipe 14 through the booster pipe 16. The water pressure is increased to ensure that the pressure of the tap water inlet is sufficient to meet the pressure requirements of the water use point.

[0053] The tap water in the first drainage pipe 11 will enter the booster bottle 20 through the bridge frame 21 and the elbow 22. After the water volume in the booster bottle 20 increases rapidly, the water pressure in the water supply pipe 14 of the first drainage pipe 11 is increased, and finally the water is used in the household through the household branch pipe 15.

[0054] During the process of pressurizing the booster bottle 20, tap water will flow into the water supply pipe 14 as the water is supplied. Due to the different water flow speeds, the water level in the booster bottle 20 will drop, but the water pressure after the drop cannot be guaranteed. Therefore, the tap water in the pressurizing pipe 16 is introduced into the booster bottle 20 through the shunt pipe 35 to ensure that the water pressure in the booster bottle 20 remains sufficient.

[0055] As the water supply pressure increases, the airbag 32 is squeezed, and the air flows through the parallel pipe 19 into the air chamber at the top of the booster tank 6, squeezing the piston plate 10 to drive the filter plate 29 to move downward. When the filter plates 29 are stacked, the spring 28 is compressed to increase the water pressure in the second drain pipe 23, further increasing the water supply pressure of the submersible pump 7, and better ensuring the pressure of the tap water inlet;

[0056] It should be noted that three groups of filter plates 29 are arranged in the liquid chamber, and a through hole 31 is opened in the filter plate 29. After the air chamber and the air bag 32 are connected, the air pressure is applied to the piston plate 10, and the piston plate 10 drives the piston rod 27 and the filter plate 29 on the surface of the piston rod 27 to squeeze downward, squeezing the water under high pressure toward the submersible pump 7 for secondary pressurization.

[0057] A spring 28 is provided between adjacent filter plates 29, and the spring 28 is sleeved on the surface of the piston rod 27. The bottom of the booster tank 6 is connected to a second drain pipe 23, and the piston rod 27 is slidably inserted into the second drain pipe 23 during the vertical movement;

[0058] It should be noted that a scraper 30 is arranged around the filter plate 29, and the scraper 30 is in contact with the tank wall of the boost tank 6, so that the filter plate 29 can clean the impurities on the tank wall of the boost tank 6 during the downward movement, and the spring 28 is squeezed by the filter plate 29 during the downward movement, thereby ensuring the cleaning area of ​​the scraper 30, and at the same time, the piston rod 27 is slidably inserted in the second drain pipe 23 during the downward movement, thereby ensuring that the tap water in the boost tank 6 is discharged smoothly and the water flow pressure is increased;

[0059] It should be noted that a paddle plate 13 is provided in the first drain pipe 11. The water flow in the first drain pipe 11 is used to drive the paddle plate 13 to rotate, thereby driving the guide shaft 12 to rotate. At least five groups of paddle plates 13 are provided on the surface of the guide shaft 12. It should be noted that the paddle plate 13 is a thin plate with a blade, which realizes the smooth flow of tap water.

[0060] The present invention also discloses a water supply method of a pipe network superimposed water supply integrated device, comprising the following steps:

[0061] Step 1: Open the tap water source end pipe 1, the filter 2 and the check valve 3 to pour the tap water into the water storage tank 5 and the booster tank 6. The water in the water storage tank 5 flows into the water supply pipe 14 through the first drainage pipe 11 and enters the house through the household branch pipe 15;

[0062] Step 2: Start the submersible pump 7, and the tap water enters the water supply pipe 14 through the pressure pipe 16, increasing the water pressure to ensure that the pressure of the tap water inlet is sufficient to meet the pressure requirements of the water point;

[0063] Step three: the tap water in the first drain pipe 11 will enter the booster bottle 20 via the bridge 21 and the elbow 22. As the water supply pressure increases, the air bag 32 is squeezed, and the air flows through the parallel pipe 19 into the air chamber at the top of the booster tank 6, squeezing the piston plate 10 to drive the filter plate 29 to move downward. When the filter plate 29 is stacked, the spring 28 is compressed to increase the water pressure in the second drain pipe 23, further increasing the water supply pressure of the submersible pump 7, and better ensuring the pressure of the tap water inlet.

As the water supply pressure increases, the air bag (32) is squeezed, and the air flows through the parallel pipe (19) into the air chamber at the top of the booster tank (6), squeezing the piston plate (10) to drive the filter plate (29) to move downward. When the filter plate (29) is stacked, the spring (28) is compressed to increase the water pressure in the second drain pipe (23), further increasing the water supply pressure of the submersible pump (7), and better ensuring the pressure of the tap water inlet.
