Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipelines, and in particular to a water hammer elimination device for water conservancy pipelines. Background Technology

[0002] Water conservancy pipeline network is a complex network system composed of various water conservancy facilities and pipeline systems. It is mainly used for the transportation, allocation, distribution, discharge and related regulation and management of water resources. It is an important infrastructure to ensure water use for social production and life, ecological environment and various engineering projects.

[0003] Currently, during the rapid closure of valves in water supply pipelines within water conservancy networks, the rapid change in the velocity of the transported fluid generates a large shock wave, which damages the valves and pipelines. This is especially true for long-distance, high-lift, high-velocity water pipelines, where the water hammer generated by the sudden valve closure can cause pipeline rupture and even personal injury.

[0004] In the prior art, the patent application with publication number CN222963555U provides a buffer pressure area for high-pressure fluid through the deformation of the spring and the S-shaped grid plate flow channel, thereby eliminating high pressure in sequence. This not only protects the device itself, but also allows the fluid after pressure relief to flow back through a one-way valve, avoiding waste.

[0005] However, such devices have obvious drawbacks in practical applications: the instantaneous high pressure generated by water hammer can easily exceed the design pressure resistance of the filter, causing the filter screen to rupture, the shell to deform or the seal to fail, causing the filtration system to lose its filtration capacity, and the impurities that were originally intercepted to re-enter the pipeline, further contaminating the system; at the same time, impurities contained in the fluid can block the flow channels between the S-shaped grid plates, affecting the buffering effect, and even aggravating the damage of water hammer to pipelines and equipment.

[0006] Therefore, it is necessary to provide a water hammer elimination device for water conservancy pipelines to solve the above-mentioned technical problems. Utility Model Content

[0038] First Embodiment

[0039] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a water hammer elimination device for hydraulic pipelines provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 A schematic diagram of the internal structure of the water hammer elimination device shown; Figure 4 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 3 The enlarged schematic diagram of section C is shown. A water hammer elimination device for hydraulic pipelines includes:

[0040] First pipe 1, second pipe 2, two first delivery pipes 3, two first disassembly assemblies 4, two filter assemblies 5, two second disassembly assemblies 7, and two diversion plates 8;

[0041] The second pipe 2 is connected to the center position of the surface of the first pipe 1;

[0042] Two of the first delivery pipes 3 are symmetrically connected to both sides of the surface of the second pipe 2;

[0043] Two first disassembly components 4 are respectively disposed at one end of two first conveying pipes 3. The first disassembly component 4 includes a first disassembly box 41 and a first disassembly cover 42. The first disassembly cover 42 is threadedly connected to one end of the first disassembly box 41.

[0044] The two filter components 5 are respectively disposed inside the two first disassembly boxes 41. The filter component 5 includes a filter screen 51, two movable blocks 52 and two movable slots 53. The filter screen 51 is disposed inside the first disassembly box 41. The two movable blocks 52 are symmetrically connected to the side of the filter screen 51. The two movable slots 53 are respectively opened on the inner wall of the first disassembly box 41.

[0045] Two second disassembly components 7 are respectively disposed on one side of two first disassembly covers 42;

[0046] The two drainage plates 8 are respectively disposed inside the two second disassembly groups 7.

[0047] One end of the first disassembly box 41 is connected to a first connecting disassembly sleeve 43, and a first connecting disassembly head 44 is connected to the surface of the first connecting disassembly sleeve 43.

[0048] A buffer assembly 6 is provided inside the first disassembly box 41 and on one side of the filter screen 51. The buffer assembly 6 includes a connecting frame 61, a buffer member 62, and a bracket 63. The connecting frame 61 is connected to the inside of the first disassembly box 41, the buffer member 62 is connected to one side of the connecting frame 61, and the bracket 63 is connected between the buffer member 62 and the filter screen 51.

[0049] The second disassembly assembly 7 includes a second disassembly box 71, a second disassembly cover 72, a second connecting disassembly head 73, and a second connecting disassembly sleeve 74. The second disassembly cover 72 is connected to one end of the second disassembly box 71, the second connecting disassembly head 73 is connected to the other end of the second disassembly box 71, and the second connecting disassembly sleeve 74 is connected to the surface of the second connecting disassembly head 73.

[0050] One end of the second disassembly cover 72 is connected to a second conveying pipe 9, and a valve 10 is provided on the surface of the second conveying pipe 9.

[0051] When water hammer occurs in the water conservancy network and the water flow impact pressure increases, the water flows through the second pipe 2 into the first delivery pipe 3, and first flows through the filter component 5 in the first disassembly box 41. The filter screen 51 filters the impurities in the water flow to prevent impurities from clogging the flow channel.

[0052] The filtered water continues to flow, impacting the filter screen 51. The filter screen 51 moves within the movable groove 53 via the movable block 52 on the side, while simultaneously pushing the support 63 to squeeze the buffer member 62 in the buffer assembly 6. The buffer member 62 deforms, providing initial buffering against the impact of the water flow.

[0053] After being buffered, the water flows into the second disassembly box 71. The direction of the water flow is changed by the guiding effect of the diversion plate 8, which further disperses the impact force of the water flow and dissipates the energy of the water hammer. Then the water flows out through the second delivery pipe 9.

[0054] If it is necessary to clean the filter screen 51 or repair the buffer assembly 6, the first disassembly cover 42 can be rotated to separate it from the first disassembly box 41, and the filter screen 51 can be removed from the movable slot 53 through the movable block 52 for cleaning or replacement.

[0055] If it is necessary to inspect the internal structure of the second disassembly assembly 7, the second disassembly box 71 can be separated from the first disassembly cover 42 by the cooperation of the second connecting disassembly head 73 and the second connecting disassembly sleeve 74, which facilitates operation.

[0056] The sliding cooperation between the movable block 52 and the movable groove 53 of the filter screen 51 not only facilitates the disassembly and maintenance of the filter screen 51, but also provides a certain amount of space for movement when water flows. Combined with the buffer component 6 to enhance the buffering effect, the filter screen 51 can effectively intercept mud, sand and debris in the water, ensure the smooth flow of subsequent channels, and avoid abnormal impact caused by impurities.

[0057] The connecting frame 61 provides fixed support for the buffer 62 (such as a spring or other elastic component). The buffer 62 transmits the elastic force to the filter screen 51 through the bracket 63, absorbing part of the impact energy at the moment the water hammer is generated, thereby reducing the damage of the water flow to the pipes and devices.

[0058] The first connecting disassembly sleeve 43 and the first connecting disassembly head 44 of the first disassembly assembly 4, and the second connecting disassembly head 73 and the second connecting disassembly sleeve 74 of the second disassembly assembly 7, are all detachable, which facilitates the assembly, disassembly and replacement of each part of the device and improves maintenance efficiency.

[0059] The diversion plate 8 plays a guiding role in the second disassembly box 71. By changing the direction of water flow, it causes the water flow to form a vortex or split within the box, further consuming the kinetic energy generated by the water hammer and enhancing the water hammer elimination effect. The valve 10 can control the opening and closing of the second delivery pipe 9 and the flow rate, and adjust the water flow size according to the actual situation to optimize the water hammer elimination efficiency.

[0060] Compared with related technologies, the water hammer elimination device for hydraulic pipelines provided by this utility model has the following beneficial effects:

[0061] This utility model provides a water hammer elimination device for hydraulic pipelines. It is equipped with two first disassembly components 4 on a second pipeline 2 with two first delivery pipes 3, which work in conjunction with a filter screen 51, two movable blocks 52, two movable grooves 53, two second disassembly components 7 and two diversion plates 8. It can effectively intercept impurities in the fluid, prevent impurities from clogging the subsequent flow channel, ensure smooth fluid flow, and reduce the risk of water hammer aggravation caused by impurities from the source. With the help of the buffer component, it can absorb part of the impact energy generated by water hammer, reduce the damage of instantaneous high pressure to the filter screen and device housing, and prevent the filtration system from failing.

[0062] Second Embodiment

[0063] Please refer to the following: Figure 6 Based on the water hammer elimination device for water conservancy pipelines provided in the first embodiment of this application, the second embodiment of this application proposes another water hammer elimination device for water conservancy pipelines. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0064] Specifically, the second embodiment of this application provides a water hammer elimination device for a water conservancy pipeline network, which differs in that it further includes a protective component 11. The protective component 11 is disposed between the first conveying pipe 3, the first disassembly component 4, the second disassembly component 7, and the second conveying pipe 9. The protective component 11 includes a protective sleeve 111, a plurality of mounting blocks 112, and a plurality of bolts 113. The protective sleeve 111 is sleeved between the first conveying pipe 3, the first disassembly component 4, the second disassembly component 7, and the second conveying pipe 9. The plurality of mounting blocks 112 are respectively connected to the surface of the protective sleeve 111.

[0065] The plurality of bolts 113 are respectively disposed between the plurality of mounting blocks 112.

[0066] The protective sleeve 111 is placed at the connection of the first conveying pipe 3, the first disassembly assembly 4, the second disassembly assembly 7 and the second conveying pipe 9, so that the protective sleeve 111 completely covers the connection parts of these components.

[0067] Align the mounting blocks 112 on the surface of the protective sleeve 111, use bolts 113 to pass through the mounting blocks 112 and tighten them to fix the protective sleeve 111 to the outside of each component, thus completing the installation of the protective assembly 11.

[0068] During the operation of the water conservancy pipeline network, the protective sleeve 111 provides physical protection for the first disassembly component 4 and the second disassembly component 7 it covers, preventing external collisions and squeezing from damaging these detachable connecting parts.

[0069] Meanwhile, the protective sleeve 111 can reduce the erosion of the component connection parts by external environmental factors, slow down the aging of the components, and ensure the sealing and stability of the connection of each component.

[0070] When maintenance of internal components is required, unscrew the bolts 113 on the mounting block 112, remove the protective cover 111, and then disassemble the first disassembly component 4 and the second disassembly component 7, and inspect the internal parts.

[0071] After maintenance, reinstall the internal components, then reset the protective cover 111 and secure it with bolt 113 to restore its protective function.

[0072] Protective sleeves 111 are typically made of wear-resistant and corrosion-resistant materials, which can effectively resist external mechanical damage and environmental corrosion, and extend the service life of the device. Its overall wrap-around design can cover the connection gaps of each detachable component, reducing the risk of water leakage.

[0073] The cooperation between the mounting block 112 and the bolt 113 makes the installation and removal of the protective sleeve 111 simple, ensuring the stability of the protective sleeve 111 during normal operation without affecting the daily maintenance of the device.

[0074] Compared with related technologies, the water hammer elimination device for hydraulic pipelines provided by this utility model has the following beneficial effects:

[0075] This utility model provides a water hammer elimination device for water conservancy pipelines. A protective component 11 is set between the first conveying pipe 3, the first disassembly component 4, the second disassembly component 7, and the second conveying pipe 9 to protect the first disassembly component 4 and the second disassembly component 7 that are installed in the outside.

[0076] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
