[0002] Currently, high-rise residential buildings use flow stabilizers to supplement water supply pressure due to their height, thereby meeting the water needs of residents.

[0003] In the existing technology, when the flow stabilizer is damaged, due to its large size and high internal water demand, the operator needs to stop the machine and drain the water stored in the flow stabilizer in order to repair it.

[0004] However, the aforementioned maintenance methods for the flow stabilizer compensator can lead to water supply interruptions, severely impacting residents' water usage. Summary of the Invention

[0005] The main objective of this invention is to provide a flow stabilizer tank to solve the problem in the prior art that maintenance of flow stabilizers requires shutdown and drainage of water.

[0006] To achieve the above objectives, the present invention provides a flow stabilizing tank, comprising: a buffer structure having an inlet port, a outlet port, and a buffer cavity, wherein both the inlet port and the outlet port are connected to the buffer cavity; a sealing assembly including a frame, a telescopic structure, and a sealing structure, wherein the telescopic structure is telescopically mounted on the frame, and the sealing structure is mounted on the frame and is used to seal a leak; the buffer structure is provided with multiple sets of support components spaced apart along its height direction, each set of support components including multiple support structures spaced apart along a first direction and / or a second direction, wherein the telescopic structure in its extended state can selectively engage with at least one set of support components; the height direction of the buffer structure is perpendicular to both the first and second directions; wherein, the support component among the multiple sets of support components that matches the height of the leak is selected as the selected support component, so that the telescopic structure in its extended state engages with the selected support component.

[0007] Furthermore, the buffer structure also has an installation port that communicates with the buffer cavity; the stabilizing tank also includes a cover that is detachably disposed at the installation port to block or avoid the installation port; wherein, the sealing component is inserted into the buffer cavity at a position corresponding to the selected support component through the installation port; or, the sealing component is removed from the buffer cavity through the installation port.

[0008] Furthermore, the sealing structure is made of rubber or silicone and has an expanded state to seal the leak.

[0009] Furthermore, the frame includes: a central portion, a sealing structure disposed in the central portion; multiple extension arms, the multiple extension arms being circumferentially spaced along the central portion, each extension arm having a mounting hole; wherein, there are multiple telescopic structures, the multiple telescopic structures being disposed one-to-one with the multiple extension arms, each telescopic structure being telescopically disposed within the mounting hole of its corresponding extension arm; each mounting hole extending radially along the central portion.

[0010] Furthermore, the central part has a through hole to supply gas or liquid to the inner cavity of the sealing structure.

[0011] Furthermore, the through hole is connected to the mounting hole so that the telescopic structure can be extended by introducing gas or liquid into the mounting hole.

[0012] Furthermore, the sealing assembly also includes an elastic structure disposed within the mounting hole for applying an elastic force toward the center of the telescopic structure.

[0013] Furthermore, the central part also has a transition hole, through which the through hole communicates with the mounting hole, and the diameter of the transition hole is smaller than the diameter of the mounting hole.

[0014] Furthermore, the mounting hole includes: a first hole section, in which an elastic structure is disposed; and a second hole section, in which a transition hole communicates with the second hole section through the first hole section, and a telescopic structure is telescopically disposed within the second hole section; wherein, the first hole section is a tapered hole, and the diameter of the tapered hole gradually increases along the direction from the transition hole to the second hole section.

[0015] Furthermore, the sealing assembly also includes a sealing structure disposed between the wall of the mounting hole and the telescopic structure.

[0016] Furthermore, the sealing assembly also includes: a pressure detection device, which is installed on the sealing structure to detect the pressure between the sealing structure and the cavity wall of the buffer chamber; a medium supply device, which is connected to a through hole to supply gas or liquid to the inner cavity of the sealing structure through the through hole; and a control module, which is connected to both the pressure detection device and the medium supply device. When the pressure detection value of the pressure detection device is greater than or equal to a preset pressure value, the control module controls the medium supply device to stop supplying the medium; or, reduces the medium supply flow rate or the medium supply quantity of the medium supply device.

[0017] Furthermore, the cover is made of a transparent material.

[0018] According to the technical solution of this invention, the flow stabilizing tank includes a buffer structure, a sealing component, and a support component. The inlet and outlet of the buffer structure are connected to a buffer chamber, which is used to buffer liquid. Multiple sets of support components are spaced apart along the height direction within the buffer structure.

The telescopic structure is telescopically mounted on the frame. When extended, the telescopic structure can selectively engage with at least one set of support components to restrict the position of the sealing component. The height direction of the buffer structure is perpendicular to both the first and second directions. Thus, when repairing a leak, the operator first selects the support component whose height matches the leak location from the multiple sets of support components. The telescopic structure is then operated to extend and engage with the selected support component, thus fixing the sealing component and preventing displacement or movement within the flow stabilizing tank. Afterwards, the sealing structure is operated to seal the leak, thereby achieving the purpose of local water isolation of the leak without interfering with the normal operation of the flow stabilizer. The staff can repair the leak from the outside of the flow stabilizer while it is operating normally, thus solving the problem of needing to shut down and drain the water for maintenance of the flow stabilizer in the existing technology, and meeting the water needs of the residents.

[0034] To address the issue that maintenance of flow stabilizers requires shutdown and drainage, this application provides a flow stabilizer tank.

[0035] like Figures 1 to 9As shown, the flow stabilizing tank is used in water supply equipment. The flow stabilizing tank includes a buffer structure 10, a sealing assembly 20, and a support assembly 30. The buffer structure 10 has an inlet port, a drain port, and a buffer chamber 11, both of which communicate with the buffer chamber 11. The sealing assembly 20 includes a frame 21, a telescopic structure 22, and a sealing structure 23. The telescopic structure 22 is telescopically mounted on the frame 21, and the sealing structure 23 is mounted on the frame 21 and used to seal leaks. The buffer structure 10 contains multiple sets of support assemblies 30 spaced apart along its height direction. Each set of support assemblies 30 includes multiple support structures 31 spaced apart along a first direction and / or a second direction. The telescopic structure 22 in its extended state can selectively engage with at least one set of support assemblies 30 for stopping. The height direction of the buffer structure 10 is perpendicular to both the first and second directions. Among them, the support component 30 that matches the height of the leakage port among the multiple sets of support components 30 is selected as the support component 30, so that the telescopic structure 22 in the extended state can stop and cooperate with the selected support component 30.

[0036] Applying the technical solution of this embodiment, the flow stabilizing tank includes a buffer structure 10, a sealing component 20, and a support component 30. The inlet and outlet of the buffer structure 10 are both connected to the buffer chamber 11, which is used to buffer liquid. Multiple sets of support components 30 are spaced apart along their height direction within the buffer structure 10. Each set of support components 30 includes multiple support structures 31 spaced apart along a first direction and / or a second direction. The sealing component 20 includes a frame 21, a telescopic structure 22, and a sealing structure 23. The sealing structure 23 is mounted on the frame 21 and is used to seal leaks. The telescopic structure 22 is telescopically mounted on the frame 21. In its extended state, the telescopic structure 22 can selectively engage with at least one set of support components 30 to restrict the position of the sealing component 20. The height direction of the buffer structure 10 is perpendicular to both the first and second directions. In this way, when repairing the leak is needed, the staff first selects the support component 30 from the multiple support components 30 that matches the height of the leak. Then, they operate the telescopic structure 22 to extend it and engage with the selected support component 30, thus fixing the sealing component 20 in place and preventing it from shifting or moving within the flow stabilization tank. Next, they operate the sealing structure 23 to seal the leak, achieving local water isolation of the leak without interfering with the normal operation of the flow stabilization tank. This allows the staff to repair the leak from the outside of the flow stabilization tank while it is operating normally, solving the problem of needing to shut down and drain the water for maintenance of the flow stabilization compensator in existing technologies, and meeting the water needs of residents.

[0037] In this embodiment, the flow stabilizer also includes a support 50, which is disposed on the buffer structure 10 to support the flow stabilizer and improve its placement stability. The liquid inlet is located on the side of the buffer structure 10 opposite to the support 50, and the liquid drain is located on the side of the buffer structure 10 where the support 50 is disposed. This arrangement allows the sealing structure 23 installed in the buffer structure 10 to avoid part of the water flow path, enabling the flow stabilizer to operate normally during maintenance. Furthermore, it allows the water to flow using its own gravity, eliminating the need for an additional water pump, thereby improving the water supply performance of the flow stabilizer and reducing its operating costs.

[0038] Optionally, the liquid inlet is connected to the water supply pipe, and a first valve is provided on the water supply pipe to control the liquid supply status of the water supply pipe to the liquid inlet.

[0039] Optionally, the drain hole is connected to the drain pipe, and a second valve is provided on the drain pipe to control the drainage status of the drain pipe.

[0040] In this embodiment, the buffer structure 10 is provided with four sets of support components 30 spaced apart along its height direction, so as to fix the sealing component 20 by the support components 30 at different heights, so as to ensure that the sealing component 20 can seal the leakage port at different heights in the flow stabilizing tank, thereby locally isolating the leakage port area, making it convenient for the staff to repair the leakage port from the outside of the flow stabilizing tank, thereby improving the sealing reliability of the sealing component 20.

[0041] It should be noted that the number of support components 30 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the support components 30 may consist of two, three, five, six, seven, or more groups.

[0042] In this embodiment, the first direction is the length direction of the cache structure 10, and the second direction is the width direction of the cache structure 10.

[0043] In this embodiment, each set of support components 30 includes eight support structures 31, wherein two support structures 31 are spaced apart along a second direction, and the other two support structures 31 are arranged opposite to the aforementioned two support structures 31. Two support structures 31 are spaced apart along a first direction, and the other two support structures 31 are arranged opposite to the aforementioned two support structures 31. In this way, the above arrangement increases the stopping area between the support structures 31 and the telescopic structure 22, thereby improving the stopping stability of both.

[0044] It should be noted that the number of support structures 31 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the support structures 31 may be three, four, five, six, seven, or more.

[0045] It should be noted that the arrangement of the multiple support structures 31 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0046] In other embodiments not shown in the accompanying drawings, each set of support components 30 includes a plurality of support structures 31 spaced apart along a first direction.

[0047] In other embodiments not shown in the accompanying drawings, each set of support components 30 includes a plurality of support structures 31 spaced apart along a second direction.

[0048] In this embodiment, the sealing component 20 is made of food-grade stainless steel to ensure that the sealing component 20 will not contaminate the water quality during use.

[0049] Optionally, the buffer structure 10 also has an installation port 12, which communicates with the buffer chamber 11. The flow stabilizer also includes a cover 40, which is detachably disposed at the installation port 12 to block or avoid the installation port 12. The sealing component 20 can be inserted into the buffer chamber 11 at the position corresponding to the selected support component 30 through the installation port 12; or the sealing component 20 can be removed from the buffer chamber 11 through the installation port 12. Thus, the above-mentioned arrangement of the installation port 12 and the cover 40 allows the flow stabilizer to have a normal operating state with the installation port 12 closed and a maintenance working state with the installation port 12 open, facilitating the installation of the sealing component 20 into the buffer structure 10 and reducing the difficulty of maintenance. Simultaneously, the above arrangement allows the maintenance personnel to remove the sealing component 20 through the installation port 12 after maintenance, preventing the sealing component 20 from affecting the water flow direction and velocity in the buffer chamber 11, thereby improving the water supply performance of the flow stabilizer.

[0050] Specifically, when the flow stabilizing tank needs repair, the operator first removes the cover 40, then inserts the sealing component 20 through the installation port 12 into the location of the leak in the buffer chamber 11. The telescopic structure 22 is then operated to extend and engage with the support component 30 at the height of the leak. The sealing component 20 is then operated to seal the leak through the sealing structure 23, providing localized water isolation to the leak area. The operator repairs the leak from the outside of the flow stabilizing tank. After repair, the sealing component 20 and telescopic structure 22 are operated again to restore the sealing component 20 to its initial state. The sealing component 20 is then removed through the installation port 12, and the cover 40 is reinstalled. This setup allows the operator to easily insert or remove the sealing component 20 into or from the flow stabilizing tank through the installation port 12, reducing operational difficulty. Furthermore, the cover 40 prevents dust and other impurities from falling into the buffer chamber 11, affecting water quality and potentially causing pipe blockage, thus improving the operational stability of the flow stabilizing tank.

[0051] Optionally, the sealing structure 23 is made of rubber or silicone, and has an expanded state to seal the leak opening. This configuration allows the sealing structure 23 to have both a retracted state (facilitating the installation and removal of the sealing component 20) and an expanded state (sealing the leak opening), which not only facilitates handling and transfer but also enables the sealing component 20 to perform its sealing function. Furthermore, this configuration allows for greater flexibility and variety in the material selection of the sealing structure 23, adapting to different working conditions and usage requirements, and also improves the processing flexibility for workers.

[0052] In this embodiment, the sealing structure 23 is made of rubber, which has good elasticity, allowing the sealing structure 23 to expand to a larger volume to seal the leak, thereby improving the sealing reliability of the sealing structure 23.

[0053] Specifically, when maintenance is required on the flow stabilizing tank, the operator manipulates the sealing structure 23 to continuously expand it until it abuts against the wall of the buffer chamber 11. The sealing structure 23 seals the leak and isolates the water within the leak area, while water in the remaining areas can continue to flow. This achieves localized water isolation of the leak without interfering with the normal operation of the flow stabilizing tank. After maintenance is completed, the sealing structure 23 is retracted to its original size so that the operator can remove the sealing component 20 from the installation port 12.

[0054] Optionally, the frame 21 includes a central portion 211 and a plurality of extension arms 212, with a sealing structure 23 disposed in the central portion 211. The plurality of extension arms 212 are spaced apart circumferentially along the central portion 211, and each extension arm 212 has a mounting hole 2121. Multiple telescopic structures 22 are provided, each corresponding to one of the extension arms 212, and each telescopic structure 22 is telescopically disposed within the mounting hole 2121 of its corresponding extension arm 212. Each mounting hole 2121 extends radially along the central portion 211. In this way, the above-mentioned arrangement allows the telescopic structure 22 to extend along the extension direction of the mounting hole 2121, so that the telescopic structure 22 can stop the support structure 31 and prevent the sealing component 20 from shifting or moving within the flow stabilizing tank. On the other hand, the retraction of the telescopic structure 22 into the mounting hole 2121 reduces the volume of the sealing component 20, making it easier for operators to insert or remove the sealing component 20 into or from the flow stabilizing tank through the mounting port 12, thereby reducing the difficulty of operation. At the same time, the above-mentioned arrangement of multiple extension arms 212 allows multiple telescopic structures 22 to be installed on the sealing component 20, thereby increasing the stopping area between the sealing component 20 and the support component 30, and thus improving the support stability of the support component 30 for the sealing component 20.

[0055] In this embodiment, ten extension arms 212 are arranged circumferentially along the center portion 211, and there are ten telescopic structures 22. The ten telescopic structures 22 are arranged one-to-one with the ten extension arms 212. Each telescopic structure 22 is telescopically arranged in the mounting hole 2121 of its corresponding extension arm 212 to increase the stop area between the sealing component 20 and the support component 30, thereby preventing the sealing component 20 from floating away from the predetermined position due to the buoyancy of the water and improving the sealing reliability of the sealing component 20.

[0056] It should be noted that the number of extension arms 212 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of extension arms 212 may be two, three, four, five, six, seven, or more.

[0057] It should be noted that the number of telescopic structures 22 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of telescopic structures 22 may be two, three, four, five, six, seven, or more.

[0058] Optionally, the central portion 211 has a through hole 2111 to supply gas or liquid to the inner cavity of the sealing structure 23. In this way, gas or liquid enters into the sealing structure 23 through the through hole 2111, allowing the sealing structure 23 to expand to seal the leak, thereby realizing the sealing function of the sealing structure 23.

[0059] In this embodiment, gas is supplied to the inner cavity of the sealing structure 23 through the through hole 2111. Even if the gas leaks inside the sealing structure 23, it will not affect the water quality, thereby improving the reliability of the sealing component 20.

[0060] Optionally, the through hole 2111 communicates with the mounting hole 2121, so that the telescopic structure 22 can be extended by introducing gas or liquid into the mounting hole 2121. In this way, the telescopic structure 22 can be automatically extended by introducing gas or liquid into the mounting hole 2121 to drive the telescopic structure 22 to move, without the need for an additional drive device to drive the telescopic structure 22 to extend or retract, thereby reducing the labor intensity of workers and the overall processing cost and energy consumption of the flow stabilizer.

[0061] In this embodiment, by introducing gas into the mounting hole 2121 to push the telescopic structure 22 out, gas leakage in the mounting hole 2121 will not affect the water quality, thereby improving the reliability of the sealing component 20.

[0062] Specifically, the through hole 2111 is connected to the mounting hole 2121. Gas is introduced into the mounting hole 2121 through the through hole 2111 to push the telescopic structure 22 out until the telescopic structure 22 and the support component 30 are stopped. Gas enters the sealing structure 23 through the through hole 2111, causing the sealing structure 23 to expand to seal the leak, thereby locally isolating the leak area. In this way, the interconnected through hole 2111 and mounting hole 2121 allow the sealing component 20 to expand the sealing structure 23 and extend the telescopic structure 22 simply by introducing gas through the through hole 2111, thus reducing the operating cost of the sealing component 20.

[0063] Optionally, the central portion 211 includes a vent pipe with a through hole 2111, which communicates with the sealing structure 23. The sealing assembly 20 also includes a control valve disposed on the vent pipe to control the on / off state of the vent pipe. Thus, during the process of gas being introduced into the mounting hole 2121, the control valve can first control the vent pipe to be in a disconnected state to ensure that all gas enters the mounting hole 2121 to push the telescopic structure 22 out. When the telescopic structure 22 extends to the limit stop with the support assembly 30, the control valve controls the vent pipe to be in a connected state. At this time, the gas located in the through hole 2111 can enter the sealing structure 23, causing the sealing structure 23 to expand and seal the leak.

[0064] like Figures 5 to 9 As shown, the sealing assembly 20 also includes an elastic structure 24, which is disposed within the mounting hole 2121 to apply an elastic force to the telescopic structure 22, causing it to move toward the center 211. Thus, after the gas supply is stopped, the telescopic structure 22, which is in the extended state, can automatically retract under the restoring force of the elastic structure 24, thereby achieving automatic retraction of the telescopic structure 22, improving the automation level of the sealing assembly 20, and reducing the labor intensity of the workers.

[0065] In this embodiment, the elastic structure 24 is a spring, so that the structure of the elastic structure 24 is simpler, easier to process and implement, thereby reducing the processing cost of the elastic structure 24.

[0066] Specifically, the two ends of the spring are connected to the bottom surface of the mounting hole 2121 and the end surface of the telescopic structure 22, respectively, so as to drive the telescopic structure 22 to retract through elastic force.

[0067] like Figures 5 to 9As shown, the central portion 211 also has a transition hole 2112, through which the through hole 2111 communicates with the mounting hole 2121. The diameter of the transition hole 2112 is smaller than that of the mounting hole 2121. This arrangement serves two purposes: firstly, it connects the through hole 2111 with the mounting hole 2121 via the transition hole 2112, allowing gas in the through hole 2111 to enter the mounting hole 2121 through the transition hole 2112, thus pushing the telescopic structure 22 within the mounting hole 2121 out; secondly, it provides a remaining bottom surface at the connection between the mounting hole 2121 and the transition hole 2112, facilitating the installation of the elastic structure 24. Furthermore, this arrangement enhances the structural strength of the central portion 211, improving the reliability of the sealing assembly 20.

[0068] In this embodiment, the central part 211 has ten transition holes 2112 and ten mounting holes 2121. The ten transition holes 2112 and the ten mounting holes 2121 are arranged in a one-to-one correspondence. Each transition hole 2112 is connected to its corresponding mounting hole 2121 to supply air into each mounting hole 2121.

[0069] It should be noted that the number of transition holes 2112 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be two, three, four, five, six, seven, or more transition holes 2112.

[0070] like Figures 5 to 9 As shown, the mounting hole 2121 includes a first hole section 2121a and a second hole section 2121b, with the elastic structure 24 disposed within the first hole section 2121a. A transition hole 2112 communicates with the second hole section 2121b via the first hole section 2121a, and a telescopic structure 22 is telescopically disposed within the second hole section 2121b. The first hole section 2121a is a tapered hole, with its diameter gradually increasing along the direction from the transition hole 2112 to the second hole section 2121b. This arrangement, on the one hand, allows the hole wall of the first hole section 2121a to limit and stop the telescopic structure 22, preventing excessive compression of the elastic structure 24 due to continued movement of the telescopic structure 22, thereby extending the service life of the elastic structure 24; on the other hand, the tapered hole allows for gas flow, reducing the impact force of the gas on the mounting hole 2121, thus extending the service life of the sealing assembly 20.

[0071] In this embodiment, when the telescopic structure 22 is retracted by the elastic structure 24, or moves into the mounting hole 2121 under the action of external force, the end face of the telescopic structure 22 facing the elastic structure 24 can cooperate with the limiting stop of the first hole segment 2121a, so as to prevent the telescopic structure 22 from continuing to move to the end face of the first hole segment 2121a and causing the elastic structure 24 to be over-compressed, thereby extending the service life of the elastic structure 24.

[0072] Optionally, the sealing assembly 20 also includes a sealing structure disposed between the wall of the mounting hole 2121 and the telescopic structure 22. This sealing structure reduces gas leakage at the connection point, preventing gas waste. Simultaneously, this arrangement prevents liquid in the buffer chamber 11 from entering the sealing assembly 20 through the gap between the mounting hole 2121 and the telescopic structure 22, thus affecting the normal operation of the sealing assembly 20 and improving its operational reliability.

[0073] Specifically, as the gas inside the mounting hole 2121 increases, the pressure inside the mounting hole 2121 also increases until the pressure inside the mounting hole 2121 exceeds the external water pressure, at which point the telescopic structure 22 is pushed to contact the inner wall of the buffer structure 10.

[0074] Optionally, the sealing assembly 20 further includes a pressure detection device, a medium supply device, and a control module. The pressure detection device is mounted on the sealing structure 23 to detect the pressure between the sealing structure 23 and the cavity wall of the buffer chamber 11. The medium supply device communicates with the through hole 2111 to supply gas or liquid to the inner cavity of the sealing structure 23 through the through hole 2111. The control module is connected to both the pressure detection device and the medium supply device. Specifically, when the pressure detected by the pressure detection device is greater than or equal to a preset pressure value, the control module controls the medium supply device to stop supplying the medium; or, reduce the medium supply flow rate or the medium supply quantity. In this way, during the process of supplying gas or liquid to the sealing structure 23 by the medium supply device, the expansion state of the sealing structure 23 is obtained through the pressure detection value of the pressure detection device. When the pressure detection value of the pressure detection device is greater than or equal to the preset pressure value, it is determined that the sealing structure 23 has sufficiently sealed the leak, and the sealing structure 23 does not need to continue expanding to prevent damage due to excessive expansion. The above setting realizes the automated operation of the sealing component 20, thereby improving the automation level of the sealing component 20 and reducing the labor intensity of the workers. Similarly, the above setting can accurately control the medium supply time of the medium supply device and the medium supply flow meter, thereby improving the reliability of the sealing component 20.

[0075] In this embodiment, when the worker inserts the sealing component 20 into the appropriate position within the buffer structure 10, the control module activates the medium supply device to deliver gas into the through hole 2111. During the process of gas flowing into the mounting hole 2121, the control valve can first control the vent pipe to be in a disconnected state to ensure that all gas enters the mounting hole 2121 and pushes the telescopic structure 22 out. When the telescopic structure 22 extends to the limit stop with the support component 30, the control valve controls the vent pipe to be in a connected state. At this time, the gas in the through hole 2111 can enter the sealing structure 23, causing the sealing structure 23 to expand and seal the leak. As the sealing structure 23 expands until it contacts the cavity wall of the buffer chamber 11, the pressure monitoring device's detection value begins to increase continuously until the pressure detection value is greater than or equal to the preset pressure value. At this point, it is determined that the sealing structure 23 can fully seal the leak to partially isolate the leak, thereby preventing water in the buffer chamber 11 from flowing out through the leak. At this point, the medium supply device can be stopped by the control module so that staff can repair the leak from outside the flow stabilizer tank.

[0076] In this embodiment, the cover 40 is made of a transparent material. This design allows staff to observe the interior of the buffer structure 10 through the cover 40, facilitating quick location of leaks and reducing maintenance difficulty.

[0077] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0078] The flow stabilizing tank includes a buffer structure, a sealing assembly, and a support assembly. The inlet and outlet of the buffer structure are connected to a buffer chamber for buffering liquid. The buffer structure contains multiple sets of support assemblies spaced apart along its height. Each set of support assemblies includes multiple support structures spaced apart along a first direction and / or a second direction. The sealing assembly includes a frame, a telescopic structure, and a sealing structure. The sealing structure is mounted on the frame and used to seal leaks. The telescopic structure is telescopically mounted on the frame. In its extended state, the telescopic structure can selectively engage with at least one set of support assemblies to restrict the position of the sealing assembly. The height direction of the buffer structure is perpendicular to both the first and second directions. Thus, when repairing a leak, the operator first selects the support assembly whose height matches the leak location from the multiple sets of support assemblies. Then, the telescopic structure is operated to extend and engage with the selected support assembly, thus fixing the sealing assembly in place and preventing displacement or movement within the flow stabilizing tank. Afterwards, the sealing structure is operated to seal the leak, thereby achieving the purpose of local water isolation of the leak without interfering with the normal operation of the flow stabilizer. The staff can repair the leak from the outside of the flow stabilizer while it is operating normally, thus solving the problem of needing to shut down and drain the water for maintenance of the flow stabilizer in the existing technology, and meeting the water needs of the residents.
