Description

Technical Field

[0001] This invention relates to the field of valves, and more specifically, to an anti-clogging valve. Background Technology

[0002] Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] Because domestic and industrial wastewater usually contains a lot of solid waste and silt, pipes are prone to blockage, especially pipes with valves. When wastewater flows through them, it is easy for blockages to occur at the valves, making it difficult to open the valves and preventing normal wastewater discharge.

[0004] Chinese patent CN212651436U discloses an anti-clogging valve structure. Before entering the valve, the sewage passes through a filter structure in the inlet pipe. The sewage then passes through a first filter cylinder and a second filter cylinder in the filter structure. Both the first and second filter cylinders are made of welded mesh plates, and the mesh size of the first filter cylinder is larger than that of the second filter cylinder. This facilitates the classification and filtration of impurities of different sizes, thereby purifying large particles in the sewage and preventing large particles from entering the valve and affecting its normal operation.

[0005] However, after prolonged use, a large amount of impurities will accumulate in the filter screen inside the valve. These impurities will enter the filter holes inside the filter screen and cause blockage, reducing the efficiency of water intake. At this time, the filter screen needs to be replaced. However, it is mainly connected by bolts, which requires tightening multiple sets of bolts, increasing the workload. At the same time, the bolts may become stripped due to rust and corrosion, making them difficult to remove. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide an anti-clogging valve.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An anti-clogging valve includes a valve housing, a valve stem seat fixedly connected to one side of the top of the valve housing, a partition plate fixedly connected to one side of the inner wall of the valve housing, and a water inlet provided at the middle position of the top of the partition plate.

[0009] A quick-release mechanism is fixedly connected to the inner wall of the valve housing on the side away from the partition plate, and an anti-misoperation mechanism is threadedly connected to the middle position inside the valve stem seat.

[0010] The quick-release mechanism includes a fixing ring located on one side of the inner wall of the valve housing. Four sets of fixing grooves are evenly distributed on the inner side of the fixing ring. A filter screen frame is fitted inside the fixing ring. Four connecting rods are evenly fixedly connected to the inner side of the filter screen frame. A fixing rod is slidably connected inside the four connecting rods. A driving cylinder is fixedly connected to the bottom outer side of the fixing rod. A fixing cylinder is fixedly connected to the four connecting rods close to each other. Slots are provided at the top and bottom of one side of the fixing cylinder. A rotating shaft is rotatably connected to one side of the inside of the fixing cylinder. A disc is fixedly connected to the middle position on the outer side of the rotating shaft. Four driving grooves are provided on one side of the disc. A support plate is fixedly connected to the top and bottom of the rotating shaft. A plug rod is slidably connected inside the support plate. A second spring is fitted on the outer side of the plug rod. The plug rod and the slot are mutually compatible. A self-cleaning mechanism is connected to a bearing on one side of the rotating shaft.

[0011] Furthermore, the top of the fixing rod extends into the interior of the fixing groove, the bottom of the fixing rod extends into the interior of the fixing cylinder, and the driving cylinder slides within the driving groove.

[0012] Furthermore, the self-cleaning mechanism includes a brush rod located on one side of the rotating shaft. Brush bristles are fixedly connected to the top and bottom of one side of the brush rod. A mounting shaft is fixedly connected to the middle position of the brush rod away from the brush bristles. A second through groove is opened on one side inside the mounting shaft. Five blades are fixedly connected to the outside of the mounting shaft. A third storage groove is opened inside the five blades. A third slot is opened on one side inside the five third storage grooves. An adjustment mechanism is threadedly connected to the middle position inside the mounting shaft.

[0013] Furthermore, the adjustment mechanism includes a second threaded rod with an internal threaded connection to the mounting shaft. A drive rod is rotatably connected to one side of the second threaded rod. A drive ring is fixedly connected to the top and bottom of the drive rod. Five sets of second hinge rods are evenly hinged to the side of the drive ring near the second threaded rod. An extension piece is hinged to one side of the second hinge rod. The second hinge rod is located inside the third slot. The extension piece is located inside the third receiving slot and slides against each other.

[0014] Furthermore, the anti-misoperation mechanism includes a valve stem threadedly connected to the middle position inside the valve stem seat. An annular groove is formed on the top of the outer side of the valve stem. Two rotating rods are slidably connected inside the annular groove. A rotating ring is fixedly connected to the side of the two rotating rods that are far apart from each other. Two second storage slots are symmetrically formed on both sides of the bottom inside the annular groove. A first slot is formed inside the two second storage slots. A magnet is fixedly connected to the top of the two first slots. A stop rod is slidably connected inside the two second storage slots. A sealing mechanism is fixedly connected to the bottom of the valve stem.

[0015] Furthermore, the stop bar is L-shaped and consists of a metal vertical bar and a metal horizontal bar, and the metal horizontal bar slides inside the first slot and is attracted and fixed to the magnet.

[0016] Furthermore, the sealing mechanism includes a sealing block fixed to the bottom of the valve stem, a sealing ring provided on the outer side of the sealing block, four first through grooves evenly opened on the inner side of the sealing block, four fixing plates fixedly connected to the inner surface of the sealing block, a first threaded rod threadedly connected to the middle position of the top of the sealing block, four sets of first hinge rods evenly hinged at the bottom edge of the first threaded rod, a slide rod hinged to the other end of the first hinge rod, an arc-shaped extrusion plate fixedly connected to one side of the slide rod, and a rotating mechanism fixedly connected to the top of the first threaded rod penetrating the interior of the valve stem.

[0017] Furthermore, the four arc-shaped extrusion plates are arranged in a ring shape, and the arc-shaped extrusion plates encircle the sealing ring.

[0018] Furthermore, the slide rod slides inside the fixed plate, the arc-shaped extrusion plate is located inside the first through groove and is adapted to each other, and the bottom of the first threaded rod is rotatably connected to a hinge plate, and the first hinge rod is hinged to the bottom of the hinge plate.

[0019] Furthermore, the rotating mechanism includes a rotating disk fixed to the top of the first threaded rod. Both ends of the rotating disk are provided with first storage grooves. The top of each of the two first storage grooves is provided with a second slot. The two ends of the two first storage grooves that are close to each other are fixedly connected with first springs. The ends of the two first springs that are far from each other are fixedly connected with handles. The tops of the two handles are fixedly connected with protrusions. The tops of the protrusions penetrate the interior of the second slots and slide against each other. A locking piece is rotatably connected at the middle position of the top of the rotating disk. The two ends of the locking piece are provided with locking grooves.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This solution features a quick-release mechanism that allows for the rapid removal of filter frames from the valve housing after a period of use. When the disc is rotated, the interaction between the driving cylinder and the driving groove causes the four sets of fixing rods to move out of the fixing groove and separate from each other. This releases the filter frame from the fixing ring, allowing for quick removal of the filter frame from the valve housing. This reduces the hassle of tightening multiple bolts and avoids the difficulty of disassembling and replacing the filter frame due to stripped bolt threads.

[0022] Second, this solution is equipped with a self-cleaning mechanism. When the filter screen filters the water flow in the pipe, the blades will rotate under the action of the water flow. This will drive the two sets of bristles to rotate synchronously. The bristles can continuously wipe and clean the filter screen on the filter screen, sweeping away the impurities inside the filter holes, and ensuring that the efficiency of water passage in the filter screen is not affected.

[0023] Third, this solution is equipped with an adjustment mechanism. By rotating the second threaded rod, the five extension blades can be moved out from the inside of the third receiving groove through transmission. This can effectively increase the water-facing area between the blades, thereby increasing the force of the water flow driving the blades to rotate. This allows the valve to adapt to water flow environments with different flow rates, and can drive all five blades to rotate.

[0024] IV. This solution incorporates an anti-misoperation mechanism, preventing accidental rotation of the valve stem by external forces when the valve is in either the closed or open state. This effectively avoids accidental valve stem operation that could lead to valve closure or opening, ensuring the valve's sealing performance when closed and its flowability when open, thus improving the valve's functionality. Furthermore, to prevent the valve stem from rotating, the stop rod is simply pushed into the annular groove to block the rotation, making operation simple, convenient, and quick.

[0025] V. This solution incorporates a sealing mechanism that allows the four arc-shaped compression plates to open when the valve is closed, applying pressure to the sealing ring. This ensures the sealing ring fits tightly against the inside of the water inlet, increasing the pressure at the connection between the sealing ring and the water inlet. This prevents leakage caused by excessive water pressure and improves the valve's sealing performance.

[0026] VI. This solution incorporates a rotating mechanism that allows the gripping rod to extend from the inside of the first receiving slot when the first threaded rod is rotated. This not only reduces effort when rotating the rotating disk and the first threaded rod but also increases the rotational force, resulting in greater and better extrusion force from the arc-shaped extrusion plate.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0053] Please see Figures 1 to 14 An anti-clogging valve includes a valve housing 1, a valve stem seat 4 fixedly connected to one side of the top of the valve housing 1, a partition plate 2 fixedly connected to one side of the inner wall of the valve housing 1, and a water inlet 3 opened at the middle position of the top of the partition plate 2.

[0054] A quick-release mechanism 6 is fixedly connected to the inner wall of the valve housing 1 on the side away from the partition plate 2, and an anti-misoperation mechanism 5 is threadedly connected at the middle position inside the valve stem seat 4.

[0055] The quick-release mechanism 6 includes a retaining ring 61 located on one side of the inner wall of the valve housing 1. Four sets of retaining grooves 62 are evenly distributed on the inner side of the retaining ring 61. A filter screen frame 68 is fitted inside the retaining ring 61. Four connecting rods 63 are evenly fixedly connected to the inner side of the filter screen frame 68. A retaining rod 67 is slidably connected inside the four connecting rods 63. A driving cylinder 614 is fixedly connected to the bottom of the outer side of the retaining rod 67. A retaining cylinder 64 is fixedly connected to the four connecting rods 63 at their close proximity. The top and bottom of one side of the retaining cylinder 64... The shaft 65 is rotatably connected to one side of the fixed cylinder 64, and a disc 66 is fixedly connected to the middle position of the outer side of the rotating shaft 65. Four drive slots 615 are opened on one side of the disc 66. A support plate 613 is fixedly connected to the top and bottom of the rotating shaft 65. A plug rod 611 is slidably connected inside the support plate 613. A second spring 610 is sleeved on the outer side of the plug rod 611. The plug rod 611 and the slot 612 are adapted to each other. A self-cleaning mechanism 69 is connected to a bearing on one side of the rotating shaft 65.

[0056] The top of the fixing rod 67 extends into the interior of the fixing groove 62, the bottom of the fixing rod 67 extends into the interior of the fixing cylinder 64, and the driving cylinder 614 slides inside the driving groove 615.

[0057] The existing filter screen 68 inside the valve will accumulate a lot of impurities, which will enter the filter holes inside the filter screen 68 and cause blockage of the filter holes, reducing the efficiency of water intake. At this time, the filter screen 68 needs to be replaced. However, it is mainly connected by bolts, which requires tightening multiple sets of bolts, increasing the workload. At the same time, the bolts may strip due to rust and corrosion, making it difficult to remove.

[0058] This application is equipped with a quick-release mechanism 6. When the filter frame 68 needs to be replaced, the two sets of insert rods 611 are pulled out from the inside of the slot 612, releasing the fixing effect of the rotating shaft 65. Rotating the rotating shaft 65 causes the disc 66 and the drive groove 615 to rotate simultaneously. The inclined side of the drive groove 615 presses against the drive cylinder 614, causing it to slide. The drive cylinder 614 continuously moves closer to the rotating shaft 65, causing the fixing rod 67 to move out from the inside of the fixing groove 62. At this time, the filter frame 68 and the fixing ring 61 are released from their mutual fixing effect, and the filter frame 68 can be quickly removed from the inside of the fixing ring 61 for replacement.

[0059] This design allows the filter frame 68 to be quickly removed from the valve housing 1. When the disc 66 is rotated, the four sets of fixing rods 67 move out of the fixing groove 62 and separate from each other through the cooperation between the driving cylinder 614 and the driving groove 615. This releases the filter frame 68 from the fixing ring 61, allowing the filter frame 68 to be quickly removed from the valve housing 1. This reduces the hassle of tightening multiple bolts and avoids the filter frame 68 being difficult to disassemble and replace due to stripped bolt threads, greatly improving the efficiency of disassembly.

[0060] like Figure 3 , Figure 5 and Figure 6 As shown, the self-cleaning mechanism 69 includes a brush rod 691 located on one side of the rotating shaft 65. Brush bristles 694 are fixedly connected to the top and bottom of one side of the brush rod 691. A mounting shaft 693 is fixedly connected to the middle position of the side of the brush rod 691 away from the brush bristles 694. A second through groove 692 is opened on one side inside the mounting shaft 693. Five blades 695 are fixedly connected to the outside of the mounting shaft 693. A third storage groove 696 is opened inside the five blades 695. A third slot 697 is opened on one side inside the five third storage grooves 696. An adjustment mechanism 698 is threadedly connected to the middle position inside the mounting shaft 693.

[0061] Because the filter screen 68 is in a static environment for a long time when it is working, impurities in the water will adhere to the inside of the filter holes inside the filter screen 68, causing the filter screen 68 to reduce the efficiency of water passage.

[0062] This application incorporates a self-cleaning mechanism 69, which wipes the surface of the filter frame 68, removing impurities from the filter holes. When water flows through, it drives the blades 695 to rotate. The five continuously rotating blades 695 drive the mounting shaft 693 to rotate continuously, which in turn drives the brush rod 691 and brush bristles 694 to rotate continuously. Since the brush bristles 694 are in close contact with the filter frame 68, they can continuously wipe and clean the filter frame 68, thereby removing impurities from the filter holes and ensuring the water flow efficiency of the filter frame 68.

[0063] like Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, the adjustment mechanism 698 includes a second threaded rod 6981 internally threaded to the mounting shaft 693. A drive rod 6982 is rotatably connected to one side of the second threaded rod 6981. A drive ring 6983 is fixedly connected to the top and bottom of the drive rod 6982. Five sets of second hinge rods 6984 are evenly hinged to the side of the drive ring 6983 near the second threaded rod 6981. An extension piece 6985 is hinged to one side of each second hinge rod 6984. The second hinge rods 6984 are located inside the third slot 697, and the extension pieces 6985 are located inside the third storage slot 696 and slide against each other.

[0064] Because the pressure of water flow varies in different working environments, in pipes with low water flow, the impact force of water flow on blade 695 will be reduced, causing the mounting shaft 693 to not rotate quickly, resulting in a significant reduction in the cleaning power of brush 694.

[0065] This application, by setting an adjustment mechanism 698, rotates the second threaded rod 6981, which, under the action of the thread, drives the drive rod 6982 and drive ring 6983 closer to the blade 695, pushing the second hinge rod 6984 to move. One end of the second hinge rod 6984 moves inside the third slot 697, pushing the extension piece 6985 from inside the third receiving slot 696, thereby effectively increasing the water-facing area of ​​the blade 695. The increase in the water-facing area increases the thrust of the water flow, thus ensuring the normal rotation of the brush rod 691 and the bristles 694.

[0066] like Figure 10 As shown, the anti-misoperation mechanism 5 includes a valve stem 51 threadedly connected to the middle position inside the valve stem seat 4. An annular groove 54 is provided on the top of the outer side of the valve stem 51. Two rotating rods 55 are slidably connected inside the annular groove 54. A rotating ring 53 is fixedly connected to the side of the two rotating rods 55 that are far apart from each other. Two second storage slots 59 are symmetrically provided on both sides of the bottom inside the annular groove 54. A first slot 52 is provided inside the two second storage slots 59. A magnet 56 is fixedly connected to the top inside the two first slots 52. A stop bar 57 is slidably connected inside the two second storage slots 59. A sealing mechanism 58 is fixedly connected to the bottom of the valve stem 51.

[0067] The stop bar 57 is L-shaped and consists of a metal vertical bar and a metal horizontal bar. The metal horizontal bar slides inside the first slot 52 and is attracted and fixed to the magnet 56.

[0068] In everyday environments, the valve stem 51 of existing valves is often unprotected, making it easy for workers to misoperate, causing the valve to open or close. Accidental closure or opening of the valve can lead to unpredictable consequences.

[0069] This application incorporates an anti-misoperation mechanism 5. When the valve is in operation, after the valve stem 51 has finished operating the valve, the stop rod 57 is pulled down and moved from inside the annular groove 54 to inside the second receiving groove 59, causing the stop rod 57 and the magnet 56 to separate. At this time, the rotating rod 55 lacks a limit and obstruction, and the rotating rod 55 can only rotate continuously in the annular groove 54 without driving the valve stem 51 to rotate, thus preventing the valve from opening or closing.

[0070] When the valve is in the closed or open state, the valve stem 51 will not be rotated by external force, which effectively avoids the valve stem 51 being misoperated and causing the valve to close or open. This ensures the sealing performance of the valve when closed and the fluidity when open, improving the valve's functionality. When the valve stem 51 is to be rotated, the stop rod 57 needs to be pushed into the annular groove 54 to block the rotating rod 55. The operation is simple, convenient and quick.

[0071] like Figure 11 As shown, the sealing mechanism 58 includes a sealing block 581 fixed to the bottom of the valve stem 51. A sealing ring 582 is provided on the outer side of the sealing block 581. Four first through grooves 586 are evenly opened on the inner side of the sealing block 581. Four fixing plates 589 are fixedly connected to the inner surface of the sealing block 581. A first threaded rod 588 is threadedly connected to the middle position of the top of the sealing block 581. Four sets of first hinge rods 584 are evenly hinged to the bottom edge of the first threaded rod 588. A slide rod 585 is hinged to the other end of the first hinge rod 584. An arc-shaped extrusion plate 583 is fixedly connected to one side of the slide rod 585. The top of the first threaded rod 588 penetrates the interior of the valve stem 51 and is fixedly connected to a rotating mechanism 587.

[0072] The four arc-shaped extrusion plates 583 are arranged in a ring, and the arc-shaped extrusion plates 583 encircle the sealing ring 582.

[0073] The slide bar 585 slides inside the fixed plate 589, the arc-shaped extrusion plate 583 is located inside the first through groove 586 and is adapted to each other, the bottom of the first threaded rod 588 is rotatably connected to a hinge plate, and the first hinge rod 584 is hinged to the bottom of the hinge plate.

[0074] After the valve is closed, it is necessary to ensure the valve's sealing performance. However, with traditional valves, the sealing plug is constantly opening and closing after being closed, which causes wear and tear, resulting in a poorer sealing effect or even leakage.

[0075] This application incorporates a sealing mechanism 58. When the sealing block 581 moves into the interior of the water inlet 3 and closes the valve, the rotating mechanism 587 drives the first threaded rod 588 to rotate synchronously. Under the action of the thread, the first threaded rod 588 continuously descends. The first threaded rod 588 rotates relative to the hinge plate, preventing the first hinge rod 584 from rotating. This pushes one end of the first hinge rod 584 downward, while the other end pushes the slide rod 585 to slide inside the fixed plate 589. This causes the arc-shaped extrusion plate 583 to enter the interior of the first through groove 586 and contact and press against the sealing ring 582. This allows the sealing ring 582 to be tightly pressed against the side wall of the water inlet 3, ensuring the pressure of the water inlet 3 during sealing and preventing leakage.

[0076] The four arc-shaped extrusion plates 583 are opened to compress the sealing ring 582 and apply a certain pressure, so that the sealing ring 582 and the inner side of the water inlet 3 are tightly fitted together. This increases the pressure at the connection between the sealing ring 582 and the water inlet 3, which can prevent leakage caused by excessive water pressure and improve the sealing performance of the valve.

[0077] like Figure 12 , Figure 13 and Figure 14 As shown, the rotating mechanism 587 includes a rotating disk 5871 fixed to the top of the first threaded rod 588. Both ends of the rotating disk 5871 are provided with first storage grooves 5875. The top of the two first storage grooves 5875 is provided with second slots 5876. The two ends of the two first storage grooves 5875 that are close to each other are fixedly connected to a first spring 5872. The two ends of the two first springs 5872 that are far from each other are fixedly connected to a handle 5873. The top of the two handles 5873 is fixedly connected to a protrusion 5874. The top of the protrusion 5874 passes through the interior of the second slot 5876 and slides against each other. A locking piece 5877 is rotatably connected at the middle position of the top of the rotating disk 5871. The two ends of the locking piece 5877 are provided with locking grooves 5878.

[0078] When rotating the first threaded rod 588, the user needs to apply a certain torque force. For users with less hand strength, this can cause the first threaded rod 588 to not rotate completely, the pressure applied by the arc-shaped extrusion plate 583 to the sealing ring 582 to be insufficient, and the rotation of the first threaded rod 588 to be quite difficult. In fact, in reality, there may not be only one valve, but a large number of valves may be working at the same time, which may lead to a lack of power later on.

[0079] This application sets up a rotating mechanism 587, and when the rotating disk 5871 is rotated to drive the first threaded rod 588 to rotate, the locking plate 5877 is rotated, which drives the two sets of locking grooves 5878 to rotate and move away from the outside of the two sets of protrusions 5874. At this time, under the elastic force of the first spring 5872, the grip 5873 can be pushed out of the inside of the first storage groove 5875. At this time, the user can hold the grip 5873 with both hands to rotate the rotating disk 5871, thus making it easier to rotate the first threaded rod 588.

[0080] Not only can it reduce the strength of the operator, but it can also rotate a large number of rotating discs 5871 in the future, avoiding insufficient pressure on the sealing ring 582 due to insufficient strength during subsequent operations, which could cause valve leakage. At the same time, the storage of the handle 5873 can prevent the rotating disc 5871 from being pushed by external force, thus avoiding accidental rotation of the rotating disc 5871 and movement of the arc-shaped extrusion plate 583, ensuring the safety of the rotating disc 5871.

[0081] Instructions for use: First, when it is necessary to disassemble the filter screen frame 68, rotating the disc 66 will cause the four sets of fixing rods 67 to move out of the inside of the fixing groove 62 and separate from each other through the cooperation between the driving cylinder 614 and the driving groove 615. This will release the filter screen frame 68 from the fixing ring 61, allowing the filter screen frame 68 to be quickly removed from the inside of the valve housing 1. This reduces the trouble of tightening multiple bolts and avoids the filter screen frame 68 being difficult to disassemble and replace due to stripped bolt threads.

[0082] Then, after the valve stem 51 has finished operating the valve, the stop rod 57 is pulled down and moved from the inside of the annular groove 54 to the inside of the second receiving groove 59, so that the stop rod 57 and the magnet 56 are separated from each other. At this time, the rotating rod 55 lacks a limit and obstruction. The rotating rod 55 can only rotate continuously in the annular groove 54, but will not drive the valve stem 51 to rotate, so it will not open or close the valve.

[0083] Finally, the sealing mechanism 58 can increase the pressure on the inner wall of the water inlet 3, effectively preventing leakage inside the valve caused by excessive water pressure.

[0084] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
