Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, it relates to a special valve for water curtain with flow rate control and filtration functions. Background Technology

[0002] In the water curtain project at the Changsha Xinhua Lian Tongguan Kiln Tower, we pumped lake water into tanks on the tower. During performances, the water flowed out of the tanks through pipes to create a water curtain effect. This required valves, but the existing valves couldn't flexibly adjust the water flow according to the situation, especially since our tower has eight sides, and some programs required different effects on each side. Therefore, we encountered operational difficulties when adjusting the water flow for different effects. This design flaw resulted in imprecise water flow control, failing to meet the specific water flow requirements of different scenarios.

[0003] Secondly, existing valves often cannot achieve a sealed state inside when water flows through the valve body. This problem may lead to internal leakage of the valve. Even when closed, water will slowly flow out, which not only wastes water resources but may also cause unnecessary damage to the surrounding environment. In addition, such leakage may also affect the long-term use of the valve and shorten its service life.

[0004] Furthermore, since there are many impurities in the lake water, filtration is necessary. However, when using existing valves, users cannot quickly replace the filter plates. The filter plates are an important component in the valve used to filter impurities. After long-term use, they may become clogged or damaged and need to be replaced regularly. However, the existing design often makes the replacement of filter plates complicated and time-consuming. Utility Model Content

[0030] Please see Figures 1-5 A special valve for a water curtain with flow rate control and filtration functions includes a valve body 1. A locking assembly is provided on the valve body 1. The locking assembly includes a connecting pipe 2, a first threaded rod 3, a handle 4, a rotating rod 5, and an anti-slip sleeve 6. The connecting pipe 2 is fixedly installed on the valve body 1. The first threaded rod 3 is threadedly connected to the connecting pipe 2. The handle 4 is provided on the first threaded rod 3. The rotating rod 5 is provided on the handle 4. The anti-slip sleeve 6 is provided on the rotating rod 5. A flow-blocking assembly is provided inside the valve body 1. The flow-blocking assembly includes a water-blocking block 7, a sliding rod 8, and an abutment block 9. The water-blocking block 7 is located inside the valve body 1. The sliding rod 8 is slidably connected to the water-blocking block 7. The abutment block 9 is connected to one end of the sliding rod 8 and is in close contact with the inside of the valve body 1.

[0031] A sealing plate 10 is slidably connected to the first threaded rod 3, and a connecting block 11 is connected to the first threaded rod 3, with one end of the connecting block 11 abutting against the sealing plate 10.

[0032] The valve body 1 is equipped with two partitions 12, and the sealing plate 10 is in close contact with the two partitions 12.

[0033] A spring 13 is fitted onto the sliding rod 8.

[0034] A flow hole 14 is provided on the water-blocking block 7.

[0035] In this embodiment, during use, when the valve body 1 is in use, the rotating rod 5 drives the handle 4 and the first threaded rod 3 to rotate. During this rotation, the first threaded rod 3 moves up and down along the connecting pipe 2, and during this up and down movement, the connecting block 11 on the first threaded rod 3 moves. When the connecting block 11 moves upward, the sealing plate 10 slidably connected to the first threaded rod 3 moves upward, allowing water to flow through the valve body 1 away from the hole 24 of the sealing plate 10. When the first threaded rod 3 is rotated in the opposite direction, the sealing plate 10 is moved upward. The water moves downward, causing the sealing plate 10 to block the hole 24 of the partition plate 12, thus blocking the flow of water. When the water flows through the valve body 1, it passes through the abutment block 9 on the valve body 1. During the continuous flow of water, the spring 13 between the water-blocking block 7 and the abutment block 9 is continuously compressed. When the water flow rate is too high, it will break the seal between the sealing block 25 and the inside of the valve body 1, allowing the water to flow through the sealing block 25 and then through the flow hole 14 to the water-blocking block 7. When the water flow is low, the abutment block 9 will be reset to its initial position under the action of the elastic potential energy of the spring 13.

[0036] Please see Figure 5 As an embodiment of a water curtain valve with flow rate control and filtration function for a filter assembly: A filter assembly is provided at one end of the valve body 1. The filter assembly includes a fixed pipe 15, a sealing gasket 16 and a filter plate 17. The fixed pipe 15 is connected to one end of the valve body 1, the sealing gasket 16 is tightly attached to one end of the fixed pipe 15, and the filter plate 17 is attached to one end of the sealing gasket 16.

[0037] A main fixing seat 18 is detachably installed on the outside of the filter plate 17 and the sealing gasket 16. A hinge seat 19 is installed at one end of the main fixing seat 18. A secondary fixing seat 20 is rotatably connected to the hinge seat 19. Both the main fixing seat 18 and the secondary fixing seat 20 are in close contact with the filter plate 17 and the fixing tube 15.

[0038] A rotating rod 21 is rotatably connected to the main fixed seat 18. A second threaded rod 22 is connected to the rotating rod 21. A threaded sleeve 23 is threadedly connected to the second threaded rod 22. One end of the threaded sleeve 23 is tightly attached to the secondary fixed seat 20. A hole 24 is opened on the partition plate 12. A sealing block 25 is installed inside the valve body 1. Both ends of the spring 13 are connected to the water-blocking block 7 and the sealing block 25.

[0039] More specifically, when water flows through valve body 1, it needs to be filtered by filter plate 17. However, if filter plate 17 is used for a long time, it will become clogged, and filter plate 17 needs to be replaced. At this time, the threaded sleeve 23 is rotated along the second threaded rod 22 to remove it from the second threaded rod 22, thereby releasing the fixing process of the second threaded rod 22. Then, the rotating rod 21 is used to drive the second threaded rod 22 to rotate and remove it. Next, the fixed seat 20 is rotated and opened along the hinge seat 19 at one end, thereby releasing the restriction and fixing process of the sealing gasket 16 and filter plate 17. The filter plate 17 is removed, cleaned or replaced, and then the filter plate 17 is placed in a position that is in close contact with the sealing gasket 16. Then, the fixed seat 20 is rotated along the hinge seat 19 to fix the second threaded rod 22 using the threaded sleeve 23.

[0040] In summary, during the use or operation of the overall equipment: When using the valve body 1, the rotating rod 5 drives the handle 4 and the first threaded rod 3 to rotate. During this rotation, the first threaded rod 3 moves up and down along the connecting pipe 2, causing the connecting block 11 on the first threaded rod 3 to move. When the connecting block 11 moves upward, it moves the slidingly connected sealing plate 10 on the first threaded rod 3 upward, allowing water to flow through the valve body 1 away from the hole 24 of the sealing plate 10. Conversely, when the first threaded rod 3 is rotated in the opposite direction, it... The moving sealing plate 10 moves downward, thereby blocking the hole 24 of the partition plate 12 and blocking the flow of water. When the water flows through the valve body 1, it passes through the abutment block 9 on the valve body 1. During the continuous flow of water, the spring 13 between the water-blocking block 7 and the abutment block 9 is continuously compressed. When the water flow rate is too high, it will break the seal between the sealing block 25 and the inside of the valve body 1, allowing the water to flow through the sealing block 25 and then through the flow hole 14 to the water-blocking block 7. When the water flow is low, the abutment block 9 will be reset to its initial position under the action of the elastic potential energy of the spring 13.

[0041] When water flows through valve body 1, it needs to be filtered by filter plate 17. However, if filter plate 17 is used for a long time, it will become clogged and needs to be replaced. At this time, the threaded sleeve 23 is rotated along the second threaded rod 22 to remove it from the second threaded rod 22, thereby releasing the fixing process of the second threaded rod 22. Then, the rotating rod 21 is used to drive the second threaded rod 22 to rotate and remove it. Next, the fixed seat 20 is rotated and opened along the hinge seat 19 at one end, thereby releasing the restriction and fixing process of the sealing gasket 16 and filter plate 17. The filter plate 17 is removed, cleaned or replaced, and then placed in a position that is in close contact with the sealing gasket 16. Then, the fixed seat 20 is rotated along the hinge seat 19 to fix the second threaded rod 22 using the threaded sleeve 23.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
