[0003] Sudden changes in water consumption can cause water hammer in urban water supply systems. Water hammer is an overpressure phenomenon caused by a sudden change in the fluid velocity in the water supply system. For example, when water consumption increases suddenly, the water consumption is greater than the water supply, and negative pressure appears in the water supply network; or when water consumption decreases suddenly, the water consumption is less than the water supply, and positive pressure appears in the water supply network. The sudden change in pressure not only damages the pipeline structure and reduces the service life of the pipeline, but also causes noise and reduces the comfort of residents.

DETAILED DESCRIPTION

[0025] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0026] Reference Figure 1 This embodiment provides a silent non-negative pressure water supply device, including a water supply module 1, a storage module 2, a driving module 3 and a water use module 4.

[0027] Reference Figures 1-2 The water supply module 1 includes a water inlet pipe 11 and a water inlet valve 12. The water inlet valve 12 is installed on the water inlet pipe 11 through a flange structure.

[0028] Reference Figures 1-2 The storage module 2 includes a flow compensator 21 and a negative pressure suppressor 22. The flow compensator 21 is a shell-shaped water tank structure, and the flow compensator 21 is fixedly connected to the ground (for example, it is placed on the ground by its own weight or installed on the ground by bolts). The flow compensator 21 is provided with an inner cavity for accommodating water, and the negative pressure suppressor 22 is placed on the top of the flow compensator 21 and is connected to the top of the inner cavity of the flow compensator 21. The flow compensator 21 is provided with a water inlet and a drain, the water inlet is connected to the upper part of the inner cavity of the flow compensator 21, and the drain is connected to the bottom of the inner cavity of the flow compensator 21. The water inlet is connected to the water inlet pipe 11 of the water supply module 1 (for example, it is installed by welding or by a flange). The negative pressure suppressor 22, for example, adopts an air valve, which is a conventional existing technology in the industry and will not be described in detail.

[0029] Reference Figures 1-2 The driving module 3 includes a water distribution main pipe 31, a water distribution branch pipe 32, a driving assembly 33 and a check valve 34. The water distribution main pipe 31 is connected to the drain port (for example, by welding or by flange), and the water distribution main pipe 31 is connected to a plurality of water distribution branch pipes 32 (for example, by welding or by flange), and the plurality of water distribution branch pipes 32 are connected in parallel. The water distribution branch pipe 32 is connected to one end of the driving assembly 33, and the other end of the driving assembly 33 is connected to the check valve 34; the driving assembly 33 is a silent driver.

[0030] Reference Figures 1-2 The water module 4 includes a water outlet main pipe 41, and the check valve 34 is connected to the water outlet main pipe 41 through a pipeline (for example, installed by welding or by a flange).

[0031] When the water flow rate at the water inlet of the flow stabilizing compensator 21 is less than the drainage flow rate of the water outlet main 41 (for example, during the peak period of residential water use), negative pressure will be generated in the flow stabilizing compensator 21 and the driving module 3. The negative pressure suppressor 22 should be opened by manual or electromechanical control to allow air to flow into the flow stabilizing compensator 21 through the negative pressure suppressor 22, thereby reducing the negative pressure in the flow stabilizing compensator 21 and the driving module 3 and avoiding damage to the equipment due to pressure. When the water flow rate at the water inlet of the flow stabilizing compensator 21 is greater than the drainage flow rate of the water outlet main 41 (for example, during the low peak period of residential water use), positive pressure will be generated in the flow stabilizing compensator 21 and the driving module 3. The negative pressure suppressor 22 should be opened by manual or electromechanical control to increase the water level in the flow stabilizing compensator 21 and discharge the air in the flow stabilizing compensator 21 through the negative pressure suppressor 22 (closed when the water is full), thereby reducing the positive pressure in the flow stabilizing compensator 21 and the driving module 3 and avoiding damage to the equipment due to pressure. Ultimately, it can buffer the water pressure changes in the water supply system, slow down the occurrence of water hammer, reduce vibration and noise, increase the service life of the pipeline, and improve user experience.

The tube pump 332 is, for example, a planetary gear tube pump 332, which is a conventional existing technology in the industry and will not be described in detail.

[0033] Reference Figure 3 The end of the support pipe 331 close to the check valve 34 is an open structure, and the end of the support pipe 331 close to the check valve 34 is connected to the check valve 34 through the first flange 3311. The end of the support pipe 331 away from the first flange 3311 is a sealing structure (for example, a sealing plate integrally formed with the side wall), and the side wall of the support pipe 331 close to the sealing structure is provided with a side branch pipe, which is connected to the water distribution branch pipe 32 through the second flange 3312. The inner cavity of the side branch pipe is connected to the inner cavity of the support pipe 331, and the side branch pipe and the support pipe 331 are fixedly installed by welding, by a flange, or by integrally forming.

The mounting hole 33113 and the mounting end abut against each other, and the maximum cross-section of the mounting end is greater than the minimum cross-section of the mounting hole 33113, so as to prevent the pump-in-tube 332 from falling out of the mounting hole 33113. A connecting hole 33114 is provided at the center of the second disk, and the connecting hole 33114 is connected to the mounting hole 33113. One end of the pump-in-tube 332 abuts against the first disk body 33111, and the other end of the pump-in-tube 332 abuts against the sealing structure of the support tube 331, so as to achieve fixed installation. A C-shaped protrusion is provided at the waist of the mounting end, and a C-shaped groove adapted to the C-shaped protrusion is provided at the waist of the mounting hole 33113. The C-shaped protrusion is placed in the C-shaped groove to prevent the pump 332 in the tube from rotating.

[0035] Reference Figure 3 The silent driver further includes a shielding sleeve 333, which is sleeved and fixed on the outer surface of the in-pipe pump 332 and the inner surface of the support pipe 331.

When the pump in the pipe 332 is running, it generates vibrations and drives the support pipe 331 to vibrate. The shock-absorbing throat 334 is used to offset the kinetic energy of the vibration and prevent the vibration from being transmitted to the water distribution branch pipe 32 and the check valve 34.

[0038] Reference Figure 2 A filter 13 (for example, installed by a flange) is provided between the water inlet and the water inlet valve 12. The water inlet pipe 11 is connected to the water outlet pipe of the water plant. The filter 13 is used to filter out impurities in the water to prevent the impurities from damaging the pump 332 in the pipe.
