Detailed Implementation
[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.
[0021] like Figures 1-11 The illustrated filter-type heating ball valve includes a valve body 1, with connecting pipes 2 fixedly connected to both sides of the valve body 1. One of the connecting pipes 2 has a filter disassembly mechanism 3 inside, which is used to filter solid impurities in the heating medium and facilitate disassembly and assembly. The filter disassembly mechanism 3 has an anti-clogging mechanism 4 inside, which is used to clean the filter disassembly mechanism 3. A ball 5 is rotatably connected inside the valve body 1. A valve stem 6 is fixedly connected to the top of the ball 5, and a bearing 7 is rotatably connected to the bottom of the ball 5. A pressure balancing mechanism 8 is installed inside the ball 5, which is used to balance the water pressure.
[0022] The filter disassembly mechanism 3 includes a fixed cylinder 301, which provides an installation position. Two engaging rods 302 are fixedly connected to the inner side of the fixed cylinder 301. A limiting chuck 303 is slidably connected inside the fixed cylinder 301, serving a limiting function. Multiple slots 304 are formed inside the edge of the limiting chuck 303. When the engaging rods 302 move into the slots 304, the limiting chuck 303 is fixed inside the fixed cylinder 301 on the side away from the valve body 1. The slots 304 engage with the engaging rods 302. A rotating ring 305 is rotatably connected to the side of the limiting chuck 303 away from the engaging rods 302. A tension spring 306 is provided inside the fixed cylinder 301. The rotating ring 305 allows the limiting chuck to... When 303 rotates, the tension spring 306 will not cause motion interference. A mounting bracket 307 is fixedly connected to the outside of the fixed cylinder 301, allowing the fixed cylinder 301 to be mounted. Multiple engaging grooves 308 are provided inside one of the connecting pipes 2, allowing the mounting bracket 307 to be installed inside the connecting pipe 2. Multiple blocking arc plates 309 are fixedly connected to the side of the connecting pipe 2 away from the valve body 1. Multiple positioning pins 310 are fixedly connected to the side of the blocking arc plates 309 away from the valve body 1. A fixing ring 311 is provided on the side of one of the connecting pipes 2 away from the valve body 1, and the fixing ring 311 can be blocked by the blocking arc plates 309. Multiple positioning holes 312 are provided inside the fixing ring 311. After engaging with the positioning post 310, the fixing ring 311 remains stable. A filter plate 313 is fixedly connected to the inner side of the fixing ring 311. The filter plate 313 can filter solid impurities in the heating medium. One end of the tension spring 306 is fixedly connected to the side of the rotating ring 305 near the valve body 1, and the other end of the tension spring 306 is fixedly connected to the inside of the fixing cylinder 301. Multiple blocking blocks 314 are fixedly connected to the outside of the fixing ring 311. The mounting bracket 307 engages with the inside of the engaging receiving groove 308. The blocking blocks 314 are located inside the engaging receiving groove 308. The outside of the positioning post 310 is located inside the positioning hole 312. When disassembling the filter plate 313 and the anti-clogging mechanism 4, first move the anti-clogging mechanism 4 away from the valve body 1. Pulling the chuck 303 causes it to move away from the valve body 1. When two of the notches in the slots 304 on the chuck 303 move to the engaging rod 302, the anti-blocking mechanism 4 rotates. The anti-blocking mechanism 4 causes the chuck 303 to rotate, allowing the engaging rod 302 to rotate into the slot 304. This temporarily fixes the chuck 303 inside the fixing cylinder 301, away from the valve body 1. At this time, the tension spring 306 is stretched by the chuck 303, and its reaction force causes the engaging rod 302 to press against the inside of the slot 304. This prevents the engaging rod 302 from easily leaving the slot 304 when the chuck 303 is rotated using the anti-blocking mechanism 4.Pushing the anti-clogging mechanism 4 towards the valve body 1 allows the fixed cylinder 301 to move towards the valve body 1 via the locking rod 302 and the limiting chuck 303. This, in turn, moves the mounting bracket 307 towards the valve body 1, causing it to move away from the short slot of the locking receiving groove 308. Rotating the anti-clogging mechanism 4 again allows it to rotate the fixed cylinder 301 via the limiting chuck 303, the slot 304, and the locking rod 302. The rotation of the fixed cylinder 301 then rotates the mounting bracket 307, causing it to rotate to the long slot of the locking receiving groove 308. This allows the mounting bracket 307 to be pulled out of the locking receiving groove 308, thus pulling the filter disassembly mechanism 3 out of the connecting pipe 2, completing the disassembly of the filter disassembly mechanism 3. When installing the filter disassembly mechanism 3, the locking rod 302 is also engaged in the slot 304. The mounting bracket 307 is then removed from the slot 308. The locking mechanism 308 slides into the long slot of the engaging receiving groove 308, and the anti-clogging mechanism 4 is rotated. The anti-clogging mechanism 4 drives the fixed cylinder 301 and the mounting bracket 307 to rotate, so that the mounting bracket 307 rotates to the short slot of the engaging receiving groove 308. At this time, the limiting chuck 303 is rotated so that the engaging rod 302 rotates to the notch of the locking groove 304. Then, under the tension of the tension spring 306, the limiting chuck 303 is pulled towards the valve body 1, which in turn pulls the anti-clogging mechanism 4 and the filter plate 31. 3. The fixing ring 311 and the positioning hole 312 move towards the valve body 1, allowing the positioning hole 312 to move into the outside of the positioning post 310, preventing the filter plate 313 from shaking. Simultaneously, under the reaction force of the tension spring 306, the fixing cylinder 301 and the mounting bracket 307 move away from the valve body 1, allowing the mounting bracket 307 to engage with the short groove of the engaging receiving groove 308, thus enabling the filter disassembly mechanism 3 to be installed outside the connecting pipe 2.
[0023] The anti-clogging mechanism 4 includes an installation cylinder 401, which provides an installation position. The side of the installation cylinder 401 closest to the valve body 1 is fixedly connected to the side of the limiting chuck 303 away from the tension spring 306. A tension spring 402 is installed inside the installation cylinder 401. A limiting circular plate 403 is slidably connected inside the installation cylinder 401, serving a limiting function. Multiple anti-rotation grooves 404 are provided on the outside of the limiting circular plate 403. An anti-rotation strip 405 is fixedly connected inside the installation cylinder 401. The cooperation between the anti-rotation strip 405 and the anti-rotation grooves 404 allows the limiting circular plate 403 to move forward when the installation cylinder 401 rotates. The anti-rotation groove 404 is slidably connected to the outside of the anti-rotation strip 405. A movable rod 406 is fixedly connected to the side of the limiting circular plate 403 away from the tension spring 402. The movable rod 406 can slide inside the mounting cylinder 401. A fixing plate 407 is fixedly connected to the end of the movable rod 406 away from the mounting cylinder 401, providing the installation position. Two cleaning brushes 408 are fixedly connected to the side of the fixing plate 407 near the filter plate 313, cleaning brushes 408 can clean the filter plate 313. A transmission rod 409 is fixedly connected to the end of the limiting chuck 303 away from the mounting cylinder 401. An impeller 410 is fixedly connected to one end of the mounting cylinder 401. The outside of the mounting cylinder 401 is rotatably connected to the middle of the filter plate 313. One end of the tension spring 402 is fixedly connected to the end of the limiting circular plate 403 away from the fixed plate 407, and the other end of the tension spring 402 is fixedly connected to the inside of the mounting cylinder 401. The transmission rod 409 is rotatably connected to the end of the fixed cylinder 301 away from the fixed plate 407. The movable rod 406 passes through the end of the mounting cylinder 401 away from the limiting chuck 303. The connecting pipe 2, which is equipped with the filter disassembly mechanism 3 and the anti-clogging mechanism 4, is the water inlet. At this time, water flows through the filter plate 313 into the connecting pipe 2. The internal mechanism drives the impeller 410 to rotate, which in turn drives the transmission rod 409 and the mounting cylinder 401 to rotate. The anti-rotation strip 405 and the limiting circular plate 403 drive the movable rod 406 and the fixed plate 407 to rotate, which in turn drives the cleaning brush 408 to rotate. The cleaning brush 408 then cleans the filter plate 313. The tension of the tension spring 402 causes the movable rod 406 and the limiting circular plate 403 to be pulled so that the fixed plate 407 and the cleaning brush 408 are pressed tightly against the outside of the filter plate 313, thereby cleaning the filter plate 313.
[0024] The pressure balancing mechanism 8 includes four connecting slots 801, which provide pressure relief channels. The four connecting slots 801 are respectively located inside the upper and lower sides of the sphere 5. Each of the upper and lower sides of the sphere 5 has an installation slot 802, which provides an installation position. Inside the sphere 5, within the installation slots 802, are two fixing slots 803. A filter cylinder 804 is installed inside the installation slot 802, providing an installation position. A filter screen 805 is fixedly connected inside the filter cylinder 804, serving a filtering function to prevent the heating medium from... Fine particulate matter enters the sphere 5. The filter cartridge 804 has receiving slots 806 on both sides inside, providing an installation position. A return spring 807 is installed inside the receiving slot 806. A limiting plate 808 is slidably connected inside the receiving slot 806, providing a limiting function. A locking ear 809 is fixedly connected to the side of the limiting plate 808 away from the return spring 807. The locking ear 809 engages with the fixing slot 803 to complete the installation of the filter cartridge 804. One end of the return spring 807 is fixedly connected to the receiving slot. On the inner wall of groove 806, the other end of return spring 807 is fixedly connected to the side of limiting plate 808 away from locking ear 809. When installing filter screen 805, first press locking ear 809 into the mounting groove 806, thereby moving limiting plate 808 into the mounting groove 806 and compressing return spring 807 using limiting plate 808. At this time, filter cylinder 804 is placed into mounting groove 802 and rotated. When locking ear 809 moves to fixed groove 803, the return spring 807 can be compressed under the reaction force. The limiting plate 808 and the locking lug 809 are moved away from the filter cylinder 804, so that the locking lug 809 can be engaged inside the fixing groove 803, and the filter cylinder 804 can be installed inside the mounting groove 802. This allows the filter screen 805 to be installed inside the mounting groove 802. When disassembling, since the locking lug 809 is a curved surface, the filter cylinder 804 can be rotated counterclockwise to squeeze the locking lug 809 into the housing groove 806, and the filter cylinder 804 can be pulled out of the mounting groove 802 to disassemble the filter cylinder 804.
[0025] Working principle: When disassembling the filter plate 313 and the anti-clogging mechanism 4, first pull the anti-clogging mechanism 4 away from the valve body 1. This will cause the limiting chuck 303 to move away from the valve body 1. When two of the notches in the notches 304 on the limiting chuck 303 move to the engaging rod 302, rotate the anti-clogging mechanism 4. The anti-clogging mechanism 4 will then cause the limiting chuck 303 to rotate, allowing the engaging rod 302 to rotate into the notch 304. This temporarily fixes the limiting chuck 303 inside the fixing cylinder 301 away from the valve body 1. At this time, the tension spring 306 is stretched by the limiting chuck 303, and its reaction force causes the engaging rod 302 to resist... Inside the slot 304, the locking rod 302 is not easily disengaged from the slot 304 when the anti-blocking mechanism 4 rotates the limiting chuck 303. This pushes the anti-blocking mechanism 4 towards the valve body 1, and through the locking rod 302 and the limiting chuck 303, it moves the fixed cylinder 301 towards the valve body 1. This, in turn, moves the mounting bracket 307 towards the valve body 1, causing it to leave the short groove of the locking receiving groove 308. When the anti-blocking mechanism 4 is rotated again, it can then rotate the fixed cylinder 301 through the limiting chuck 303, the slot 304, and the locking rod 302. The rotation of the fixed cylinder 301 then moves the mounting bracket 307 away from the valve body 1. Rotate the mounting bracket 307 to the long slot of the engaging receiving groove 308. Then, pull the mounting bracket 307 out of the engaging receiving groove 308, allowing the filter disassembly mechanism 3 to be pulled out of the connecting pipe 2, thus completing the disassembly of the filter disassembly mechanism 3. When installing the filter disassembly mechanism 3, engage the engaging rod 302 inside the slot 304. Then, slide the mounting bracket 307 into the long slot of the engaging receiving groove 308 and rotate the anti-clogging mechanism 4. The anti-clogging mechanism 4 will drive the fixed cylinder 301 and the mounting bracket 307 to rotate, causing the mounting bracket 307 to rotate to the short slot of the engaging receiving groove 308. Then, rotate the limiting chuck 303 to engage. When rod 302 rotates to the notch of slot 304, it can pull the limiting chuck 303 toward valve body 1 under the tension of tension spring 306. This will pull the anti-clogging mechanism 4, filter plate 313, fixing ring 311, and positioning hole 312 toward valve body 1. This will allow the positioning hole 312 to move into the outside of positioning post 310, preventing the filter plate 313 from shaking. At the same time, under the reaction force of tension spring 306, the fixing cylinder 301 and mounting bracket 307 will move away from valve body 1. This will allow the mounting bracket 307 to engage in the short groove of engagement receiving groove 308, thereby allowing the filter disassembly mechanism 3 to be installed outside the connecting pipe 2. The connecting pipe 2, equipped with the filter disassembly mechanism 3 and the anti-clogging mechanism 4, serves as the water inlet. When water flows through the filter plate 313 into the interior of the connecting pipe 2, it drives the impeller 410 to rotate, thereby driving the transmission rod 409 and the mounting cylinder 401 to rotate. The anti-rotation strip 405 and the limiting round plate 403 drive the movable rod 406 and the fixed plate 407 to rotate, thereby driving the cleaning brush 408 to rotate. The cleaning brush 408 can then clean the filter plate 313. Furthermore, the tension of the tension spring 402 causes the movable rod 406 and the limiting round plate 403 to be pulled so that the fixed plate 407 and the cleaning brush 408 are pressed tightly against the outside of the filter plate 313, thus cleaning the filter plate 313. When installing filter screen 805, first press the locking lug 809 into the mounting groove 806, which will move the limiting plate 808 into the mounting groove 806 and compress the return spring 807. Then, place the filter cartridge 804 into the mounting groove 802 and rotate it. When the locking lug 809 moves into the fixing groove 803, the reaction force of the return spring 807 will push the limiting plate 808 and the locking lug 809 away from the filter cartridge. The direction of 804 is moved so that the locking lug 809 can be locked inside the fixing groove 803, so that the filter cartridge 804 is installed inside the mounting groove 802, thereby enabling the filter screen 805 to be installed inside the mounting groove 802. When disassembling, since the locking lug 809 is a sloping curved surface, the filter cartridge 804 can be rotated counterclockwise to squeeze the locking lug 809 into the mounting groove 806, and the filter cartridge 804 can be pulled out of the mounting groove 802 to disassemble the filter cartridge 804.
