Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, specifically a valve structure for diverting and switching pipelines. Background Technology

[0002] In the wastewater treatment industry, the valve structure of the diversion and switching pipeline is a key component to ensure the smooth operation of the wastewater treatment process. By precisely controlling the flow direction and flow rate of wastewater, sludge and treatment agents, it realizes a series of treatment processes such as sedimentation, filtration and disinfection of wastewater, ensuring that the effluent water quality meets the standards. The valve structure used in existing wastewater treatment pipelines is mostly assembled with the pipeline by means of threaded connection, flange connection and other methods to complete the diversion and switching operation of fluids at different treatment stages.

[0003] However, the internal pipeline layout of sewage treatment plants is intricate and complex. Due to limitations in plant space and equipment installation location, some valves are often suspended after installation. Because sewage contains a large amount of suspended solids, impurities, and corrosive chemicals, suspended valves lack stable support. Under the pressure fluctuations caused by sewage flow and the system vibrations caused by pump operation, they are prone to shaking and displacement. This not only accelerates the wear of valve seals, leading to a decrease in sealing performance and leakage of polluting sewage, polluting the surrounding environment, but also significantly shortens the valve's service life and increases equipment replacement costs due to abnormal friction and stress on the valve's internal components. Utility Model Content

[0004] To overcome the problem that existing valve structures used for diversion and switching pipelines are often suspended and thus have poor stability, this utility model provides a valve structure for diversion and switching pipelines that has the effect of supporting suspended valves.

[0028] This utility model provides a valve structure for diverting and switching pipelines.

[0029] See Figures 1 to 7 The valve structure for diverting and switching pipelines includes a valve body 1 and a base 5. The base 5 is located below the valve body 1. Two sets of locking blocks 4 are welded to the outside of the valve body 1. A support component 2 is provided on the top of the base 5. A drive component 3 is provided inside the base 5, and one side of the drive component 3 is fixedly connected to one side of the support component 2.

[0030] First, refer to Figures 1 to 5In this embodiment, the support assembly 2 includes a mounting plate 201, which is bolted to the top of the base 5. Two sets of support plates 206 are welded to the top of the mounting plate 201, and a horizontal plate 205 is welded between the two sets of support plates 206. Two sets of connecting plates 204 are slidably connected to the outer side of the horizontal plate 205. A limit rod 213 is welded inside the connecting plate 204, and the limit rod 213 is slidably connected inside the horizontal plate 205. A clamping block 203 is welded to the top of the connecting plate 204, and the clamping block 203 is engaged with the clamping block 205. On the outer side of block 4, a placement plate 209 is welded between two sets of connecting plates 204, and two sets of guide plates 202 are welded between the connecting plate 204 and the placement plate 209. The guide plates 202 are inclined. Two sets of sliders 208 are slidably connected inside the mounting plate 201. The bottom of the slider 208 is fixedly connected to one side of the drive assembly 3. A central shaft 207 is welded to the top of the slider 208. A pulley 211 is rotatably connected to the outer side of the central shaft 207, and the outer side of the pulley 211 contacts one side of the guide plate 202.

[0031] Specifically, to prevent the slider 208 from becoming misaligned, two sets of balance bars 212 are welded inside the mounting plate 201. The slider 208 is slidably connected inside the balance bars 212. Thus, on the one hand, the balance bars 212 maintain the balance of the slider 208 during movement, preventing the slider 208 from becoming unbalanced and wobbling, and ensuring the normal displacement of the slider 208. On the other hand, the balance bars 212 restrict the direction of the slider 208, preventing the device from failing due to misalignment of the slider 208, and ensuring the normal use of the device.

[0032] Specifically, in order to enable the connecting plate 204 to move back quickly, a first spring 210 is fixedly connected between the connecting plate 204 and the horizontal plate 205. Thus, when the connecting plate 204 is pushed, the first spring 210 will be stretched by the connecting plate 204, and when the connecting plate 204 is no longer pushed, the first spring 210 will bounce the connecting plate 204 back to its initial position quickly.

[0033] When the slider 208 moves horizontally, it will drive the pulley 211 to move by driving the central shaft 207. The movement of the pulley 211 will push the guide plate 202 to move upward. The movement of the guide plate 202 will drive the connecting plate 204 to move upward. The movement of the connecting plate 204 will change the height of the clamping block 203, thereby enabling the device to support valves of different heights.

[0034] Then, refer to Figure 2 , Figure 3 and Figure 6In this embodiment, the drive assembly 3 includes a bearing 301 and a rotating column 304. The bearing 301 is fixedly connected inside the base 5, and the rotating column 304 is rotatably disposed inside the base 5. Both ends of the rotating column 304 are fixedly connected to a first threaded tube 303 and a second threaded tube 306, respectively. The threads on the outer sides of the first threaded tube 303 and the second threaded tube 306 are in opposite directions. The end of the first threaded tube 303 away from the rotating column 304 is fixedly disposed to the middle of the bearing 301. Sleeves 3 are threaded onto the outer sides of both the first threaded tube 303 and the second threaded tube 306. 02. When the first threaded tube 303 and the second threaded tube 306 rotate, the two sets of sleeves 302 will move towards each other or away from each other. A connecting frame 305 is provided on one side of the sleeve 302. The side of the connecting frame 305 away from the sleeve 302 is fixedly set with the slider 208. A handle 308 is provided at the end of the second threaded tube 306 away from the rotating column 304. The handle 308 is located on the outside of the base 5, and a gear 307 is provided on the outside of the handle 308. Thus, the first threaded tube 303 and the second threaded tube 306 can be easily rotated through the handle 308.

[0035] When the handle 308 is turned, the handle 308 will drive the second threaded tube 306 to rotate. The rotation of the second threaded tube 306 will drive the first threaded tube 303 to rotate by driving the rotating column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will drive the two sets of sleeves 302 to move linearly. The displacement of the sleeves 302 will drive the connecting frame 305 to move. The movement of the connecting frame 305 will push the slider 208 to move laterally.

[0036] Finally, see Figure 2 and Figure 7 In this embodiment, a fixing block 8 is provided on one side of the base 5, and a movable plate 6 is slidably provided on the outer side of the fixing block 8. A rack 10 is provided on one side of the movable plate 6, and the rack 10 meshes with the gear 307. A second spring 9 is provided on the side of the movable plate 6 away from the rack 10. A disc 7 is provided at the end of the second spring 9 away from the rack 10. One side of the disc 7 is fixedly provided with the fixing block 8. When the rack 10 and the gear 307 are meshed, the handle 308 will not be able to rotate. When the rack 10 is moved to disengage from the gear 307, the handle 308 will no longer be fixed, and the operator can easily rotate the handle 308.

[0037] The valve structure for diverting and switching pipelines, by setting a base 5, a connecting plate 204, and a clamping block 203, can provide support for the valve body 1, avoiding the lack of stability of the valve body 1 in a suspended state. At the same time, through the cooperation between the pulley 211 and the guide plate 202, the height of the clamping block 203 and the connecting plate 204 can be adjusted, thereby enabling the device to provide support for valves of different heights and increasing the range of applications of the device.

[0038] Working principle:

[0039] The valve structure used for diverting and switching pipelines operates by first inserting the clamp 203 into the outer side of the clamp 4. At this point, the base 5, connecting plate 204, and clamp 203 will support the valve body 1. When the height of the clamp 203 needs to be adjusted, the rack 10 is moved to disengage from the gear 307. Then, the handle 308 is turned to rotate the second threaded tube 306. The rotation of the second threaded tube 306 will drive the first threaded tube 303 to rotate by driving the rotating column 304. The rotation of the first threaded tube 303 and the second threaded tube 306 will cause the two sets of sleeves 302 to move linearly. The displacement of the sleeves 302 will cause the connecting frame 305 to move. The movement of the connecting frame 305 will push... When slider 208 moves horizontally, it will drive pulley 211 to move by driving central shaft 207. The movement of pulley 211 will push guide plate 202 to move upward. The movement of guide plate 202 will drive connecting plate 204 to move upward. The movement of connecting plate 204 will change the height of clamping block 203, thereby enabling the device to support valves of different heights. At the same time, after releasing rack 10, second spring 9 will drive rack 10 to move back by springing disc 7, thereby making rack 10 mesh with gear 307 or lock gear 307, thereby fixing handle 308 and preventing it from rotating, so that clamping block 203 is stably located in the current position.

All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
