[0026] Please see Figure 1-5 This utility model provides a technical solution:

[0027] Valve body 1: As the main frame of the entire regulating valve and the core channel for fluid delivery, it provides installation space for various internal components, while bearing fluid pressure to ensure stable fluid delivery inside. It is the basic carrier for realizing flow regulation and anti-clogging functions.

[0028] Valve plate 2: Rotatably installed inside valve body 1, it changes the flow cross-sectional area inside valve body 1 by adjusting its own rotation angle, thereby controlling the fluid flow rate. It can increase, decrease or cut off the flow rate and is the core component for completing flow regulation.

[0029] Circular mesh frame 3: Slidably installed inside the valve body 1 and located on the left side of the valve plate 2, the filter screen 4 is fixed inside, providing support and fixation for the filter screen 4, and at the same time, it is fixed by adapting to the valve body 1, ensuring that the filter screen 4 can stably perform the filtering function, and also facilitating the overall disassembly and assembly.

[0030] Filter 4: Fixed inside the circular mesh frame 3, located on the left side of the valve plate 2, it performs pre-filtration on the fluid flowing into the valve body 1, intercepts solid impurities in the fluid, prevents impurities from accumulating and causing the valve plate 2 to jam or the valve body 1 to become blocked, and ensures the cleanliness of the fluid.

[0031] Fixed column 5: Fixedly installed at the center point on the left side of filter screen 4, with cleaning scraper 6 rotatably sleeved on its outer surface, providing a rotation support point for cleaning scraper 6 so that cleaning scraper 6 can rotate stably around it in order to scrape and clean impurities on the surface of filter screen 4.

[0032] Cleaning scraper 6: It is rotatably installed on the left side of the filter screen 4 via the fixed column 5. It can rotate around the fixed column 5. Its scraping end can make close contact with the left side surface of the filter screen 4. When rotating, it scrapes off the impurities attached to the surface of the filter screen 4, thereby cleaning and maintaining the filter screen 4.

[0033] Locking bolt 7: Set in the mounting groove 12 of the cleaning scraper 6, it is threadedly matched with the threaded hole 13 on the left side of the circular mesh frame 3. It is used to fix the position of the cleaning scraper 6 and prevent it from rotating randomly under the impact of fluid. It can be loosened to release the fixation during cleaning.

[0034] Slot 8: It is formed on the upper and lower surfaces of the inner wall of the valve body 1 and is slidably adapted to the locking blocks 10 on both sides of the circular mesh frame 3. The circular mesh frame 3 is fixed in the valve body 1 by locking the locking blocks 10, so as to ensure that the circular mesh frame 3 does not shift under the impact of fluid.

[0035] Slide 9: It is opened on the upper and lower sides of the circular grid frame 3 to provide sliding space for the locking block 10, so that the locking block 10 can move in and out of the slot. In conjunction with the pressure spring 14, the locking block 10 can pop out and retract, thus meeting the needs of fixing and disassembling the circular grid frame 3.

[0036] Locking block 10: It is slidably connected in the slide groove 9, and the opposite end is connected to the pressure spring 14 and passes through the circular mesh frame 3. It can extend out and lock into the locking groove 8 under the action of the pressure spring 14 to fix the circular mesh frame 3; when it is retracted, it can be released to facilitate the disassembly and assembly of the circular mesh frame 3.

[0037] Sealing pull plate 11: Fixed to the left end of the limiting plate 16, located on the upper and lower sides of the filter screen 4 and sliding in contact with the left side of the circular mesh frame 3. When pulled, it drives the limiting plate 16 and the locking block 10 to move, while preventing fluid from leaking from the limiting groove 15 and ensuring the sealing of the valve body 1.

[0038] Mounting slot 12: It is located at the end of the cleaning scraper 6 away from the fixing post 5, and a locking bolt 7 is placed inside it. It provides an installation position for the locking bolt 7, so that the locking bolt 7 can be engaged with the threaded hole 13 through the slot to fix the cleaning scraper 6.

[0039] Threaded hole 13: It is opened on the left side of the circular mesh frame 3 and is threaded to the locking bolt 7. Through the threaded connection with the locking bolt 7, the cleaning scraper 6 is fixed in the designated position to ensure that the cleaning scraper 6 is stable in the non-cleaning state.

[0040] Pressure spring 14: Fixed between the inner wall of the slide groove 9 and the opposite end of the locking block 10, it always applies a spring force to the locking block 10 in the direction away from the slide groove 9, pushing the locking block 10 out of the slide groove 9 and into the locking groove 8, providing power for the locking block 10 to fix the circular grid frame 3.

[0041] Limiting groove 15: It is opened on the left side of the circular grid frame 3 and communicates with the sliding groove 9. It provides sliding space for the limiting plate 16, restricts the movement direction of the limiting plate 16, ensures that the limiting plate 16 drives the locking block 10 to extend and retract stably, and avoids fluid leakage.

[0042] Limiting plate 16: It is slidably connected in the limiting through groove 15, with its right end fixed to the locking block 10 and its left end fixed to the sealing pull plate 11. It serves to connect the sealing pull plate 11 and the locking block 10, so that the sealing pull plate 11 can drive the locking block 10 to move in the sliding groove 9.

[0043] A clog-resistant regulating valve includes a valve body 1 and a valve plate 2. The valve plate 2 is rotatably installed inside the valve body 1. A circular mesh frame 3 is slidably installed inside the valve body 1. A filter screen 4 is fixedly installed inside the circular mesh frame 3. The filter screen 4 is located on the left side of the valve plate 2. Sliding grooves 9 are provided on both the upper and lower sides of the circular mesh frame 3. An installation assembly is provided inside the circular mesh frame 3. The installation assembly includes two locking blocks 10. The outer surfaces of the two locking blocks 10 are slidably connected to the inner walls of the corresponding sliding grooves 9. Pressure springs 14 are fixedly installed on the opposite ends of the two locking blocks 10. The opposite ends of the two pressure springs 14 are fixedly connected to the inner walls of the corresponding sliding grooves 9.

[0044] Furthermore, two limiting slots 15 are provided on the left side of the circular grid frame 3. The two limiting slots 15 are respectively connected to the interior of the corresponding sliding groove 9. Limiting plates 16 are slidably connected inside the two limiting slots 15. The right ends of the two limiting plates 16 are respectively fixedly connected to the left ends of the corresponding locking blocks 10. Sealing pull plates 11 are fixedly installed on the left ends of the two limiting plates 16.

[0045] Furthermore, the two sealing pull plates 11 are located on the upper and lower sides of the filter screen 4, respectively. The right side of the two sealing pull plates 11 is in sliding contact with the left side of the circular mesh frame 3, and the two sealing pull plates 11 are located on the left side of the corresponding limiting groove 15.

[0046] Furthermore, a fixing post 5 is fixedly installed at the center point on the left side of the filter screen 4. A cleaning scraper 6 is rotatably sleeved on the outer surface of the fixing post 5. An installation groove 12 is provided at the end of the cleaning scraper 6 away from the fixing post 5. A locking bolt 7 is provided inside the installation groove 12.

[0047] Furthermore, a threaded hole 13 is provided on the left side of the circular grid frame 3, and the interior of the threaded hole 13 is adapted to the thread of one end of the locking bolt 7.

[0048] Furthermore, the opposite ends of the two locking blocks 10 slide through to the upper and lower sides of the circular mesh frame 3 respectively, and the upper and lower surfaces of the inner wall of the valve body 1 are provided with locking grooves 8, and the interior of the two locking grooves 8 are respectively slidably adapted to one end of the corresponding locking block 10.

[0049] Furthermore, the valve body 1 serves as the core channel for fluid transport. The valve plate 2 is rotatably mounted inside the valve body 1 and can adjust its rotation angle by the valve stem to change the flow cross-sectional area inside the valve body 1: when it is necessary to increase the fluid flow rate, the valve plate 2 rotates away from the inner wall of the valve body 1, reducing the obstruction area for the fluid; when it is necessary to reduce the flow rate or cut off the fluid, the valve plate 2 rotates towards the inner wall of the valve body 1, increasing the obstruction area for the fluid, thereby achieving precise control of the fluid transport volume. This is the basic function of the regulating valve and is common knowledge in the prior art. The above content is briefly disclosed.

[0050] Furthermore, when the fluid flows in from the inlet end of the valve body 1, it first passes through the filter screen 4. Solid impurities (such as particles, debris, etc.) in the fluid are intercepted by the filter screen 4, and the filtered clean fluid can then flow to the valve plate 2 and be discharged through the outlet end of the valve body 1.

[0051] Furthermore, when the filter screen 4 needs to be inspected and maintained, the circular mesh frame 3 and the filter screen 4 can be disassembled as a whole. During disassembly, the sealing pull plates 11 on the upper and lower sides are pulled towards the center of the circular mesh frame 3. The sealing pull plates 11 drive the limiting plate 16 fixedly connected to it to slide in the limiting groove 15. The limiting plate 16 further pulls the locking block 10 in the slide groove 9 to retract into the slide groove 9, while compressing the pressure spring 14. When the locking block 10 completely disengages from the locking groove 8 on the inner wall of the valve body 1 and retracts into the slide groove 9, the fixed relationship between the circular mesh frame 3 and the valve body 1 is released. At this time, the circular mesh frame 3 can be pulled out from the inside of the valve body 1. The operation process is simple and quick, and the filter screen can be disassembled quickly.

[0052] Furthermore, when it is necessary to clean the disassembled filter screen 4, first loosen the locking bolt 7 in the mounting groove 12 so that it is disengaged from the threaded hole 13 on the left side of the circular mesh frame 3, thereby releasing the fixation restriction on the cleaning scraper 6; then push the cleaning scraper 6 to rotate around the fixed column 5, and the scraping end of the cleaning scraper 6 will be in close contact with the left side surface of the filter screen 4. During the rotation, the impurities attached to the surface of the filter screen 4 can be scraped off, and the scraped impurities can be cleaned in a concentrated manner after the filter screen is disassembled; after cleaning, rotate the cleaning scraper 6 to the initial position, re-pass the locking bolt 7 through the mounting groove 12 and screw it into the threaded hole 13, and fix the cleaning scraper 6 by the threaded engagement of the locking bolt 7 and the threaded hole 13, so as to prevent it from rotating randomly under the impact of fluid and affecting the filtration effect.

[0053] Furthermore, when reinstalling the circular mesh frame 3, first pull the sealing pull plate 11 to retract the locking block 10 into the slide groove 9, slide the circular mesh frame 3 into the valve body 1 to the designated position, ensuring that the locking block 10 is aligned with the locking groove 8. Then release the sealing pull plate 11, the pressure spring 14 returns to its deformation and pushes the locking block 10 out of the slide groove 9, and re-locks it into the locking groove 8, completing the fixing of the circular mesh frame 3. At the same time, the sealing pull plate 11 slides in contact with the left side of the circular mesh frame 3, which can prevent fluid from leaking from the limiting through groove 15 and ensure the sealing of the valve body 1.

[0054] Furthermore, the circular mesh frame 3 is fixed by the matching of the upper and lower side locking blocks 10 with the inner wall locking groove 8 of the valve body 1. Under the elastic force of the pressure spring 14, one end of the locking block 10 will always press against the inside of the locking groove 8, thereby ensuring that the circular mesh frame 3 will not be displaced under fluid impact and ensuring the filtration stability of the filter screen 4.

[0055] Furthermore, by setting up the installation components, maintenance personnel can directly slide the two sealing pull plates 11 inside the valve body, thereby enabling the filter screen 4 to be quickly installed and removed inside the valve body 1. This solves the problem of the narrow space inside the traditional valve body making it inconvenient to install and remove the filter screen, making the installation and removal of the filter screen simple and quick, and further improving the practicality of the regulating valve.

[0056] Furthermore, this anti-clogging regulating valve integrates fluid regulation and anti-clogging functions through a collaborative design of "filtration-cleaning-disassembly". It not only meets the flow control requirements of traditional regulating valves, but also effectively extends the service life of equipment and reduces maintenance costs through filter screen filtration, scraper cleaning and convenient disassembly.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
