[0002] A valve is a mechanical device that controls the flow rate, flow direction, pressure, temperature, etc. of a flowing fluid medium. A valve is a basic component in a pipeline system. In terms of technology, valve pipe fittings are the same as pumps and are often discussed as a separate category. A valve can be operated manually or by a handwheel, handle or pedal, and can also change the pressure, temperature and flow rate of the fluid medium through control. In the prior art, a valve generally does not have a filtering device. When the valve is in use, impurities in the fluid are likely to accumulate at the valve plate or inside the valve, making it difficult to clean, resulting in blockage of the valve and affecting the service life of the valve.

[0003] In view of the problems in the prior art, those skilled in the art have improved it. For example, a valve for preventing blockage with the publication number CN214861608U includes a valve body, a pipeline located below the valve body, flange plates arranged at both ends of the pipeline, and a filtering device arranged at the water inlet end of the pipeline and inside the flange plate. An annular groove is provided inside the flange plate, and the filtering device is arranged on the annular groove inside the flange plate. The filtering device includes a filter pipe adapted to the pipeline, an annular flange arranged at one end of the filter pipe and adapted to the annular groove, and a filter net arranged at the other end of the filter pipe. Its advantage is that it filters the fluid flowing through the valve body to prevent impurities in the fluid from blocking the valve, and at the same time, it is convenient to clean the filtering device, improving the service life of the valve. The disadvantage of this device is that it cannot clean the impurities inside the valve, and the filter net will hinder the flow of the fluid.

[0020] See Figures 1 to 3 , the present utility model provides a clog - proof valve, including a valve 1 and a cleaning scraper 8. The cleaning scraper 8 is arranged in the channel 2 inside the valve 1. A plurality of chutes 5 are arranged on the inner side wall of the valve 1. The openings of the chutes 5 are flush with the inner side wall of the valve 1. A plurality of sliding rods 6 are slidably connected inside the chutes 5. One end of the sliding rod 6 passes through the valve 1. The sliding rod 6 is fixedly connected to the cleaning scraper 8. The sliding rod 6 drives the cleaning scraper 8 to move. Movable rods 3 are arranged on both sides of the valve 1. One end of the movable rod 3 passes through the valve 1. A connecting plate 4 is arranged at the end of the movable rod 3 passing through the valve 1. The connecting plate 4 is connected to the sliding rod 6. An auxiliary block 7 is arranged at the other end of the movable rod 3. Threads are arranged at one end of the movable rod 3 close to the auxiliary block 7.

[0021] See Figures 1 to 3, in a further embodiment, the cleaning scraper 8 is slidably connected to the inner side wall of the channel 2. The shape of the cleaning scraper 8 completely fits the channel 2 of the valve 1, that is, the cleaning scraper 8 can clean the scale or impurities on the channel 2 of the valve 1 to avoid blockage of the channel 2 of the valve 1. Therefore, the shape of the cleaning scraper 8 is set according to the shape of the channel 2 of the valve 1.

[0022] See Figures 1 to 3 , in a further embodiment, a plurality of threaded holes 9 are provided at one end of the valve 1. The movable rod 3 is threadedly connected to the threaded holes 9, and the movable rod 3 is rotatably connected to the auxiliary block 7. When the cleaning scraper 8 does not clean the channel 2 of the valve 1, the movable rod 3 is rotated so that the threaded end of the movable rod 3 cooperates with the threaded holes 9 on the valve 1 to prevent the movable rod 3 from being mis-touched and deflected, and thus the movable rod 3 cannot move. When the cleaning scraper 8 cleans the channel 2 of the valve 1, the threaded end of the movable rod 3 is disengaged from the threaded holes 9 on the valve 1, and the auxiliary block 7 is pulled. The auxiliary block 7 drives the movable rod 3 to move, and the end of the movable rod 3 away from the auxiliary block 7 is slidably connected to one end of the valve 1.

[0023] Further, since the movable rod 3 is connected to the sliding rod 6 through the connecting plate 4, when the auxiliary block 7 drives the movable rod 3 to move, the movable rod 3 drives the sliding rod 6 to move through the connecting plate 4, and the sliding rod 6 drives the cleaning scraper 8 to move along the side wall of the channel 2 of the valve 1, thereby completing the cleaning of the side wall of the channel 2 of the valve 1.

[0024] See Figures 1 to 3 , in a further embodiment, the cleaning scraper 8 is made of a scale-proof material. After the valve 1 is used for a long time, scale will be generated to hinder the water flow rate of the valve 1. The setting of the cleaning scraper 8 can clean the scale or other impurities. The cleaning scraper 8 needs to be selected from materials that are resistant to scale or impurity adhesion to avoid impurities adhering to the cleaning scraper 8, affecting the cleaning effect and thus blocking the valve 1.

[0025] In the implementation process of the present utility model: when the cleaning scraper 8 does not clean the channel 2 of the valve 1, the movable rod 3 is rotated so that the threaded end of the movable rod 3 cooperates with the threaded holes 9 on the valve 1 to prevent the movable rod 3 from being mis-touched and deflected, and thus the movable rod 3 cannot move. When the cleaning scraper 8 cleans the channel 2 of the valve 1, the threaded end of the movable rod 3 is disengaged from the threaded holes 9 on the valve 1, and the auxiliary block 7 is pulled. The auxiliary block 7 drives the movable rod 3 to move, and the end of the movable rod 3 away from the auxiliary block 7 is slidably connected to one end of the valve 1. The movable rod 3 is connected to the sliding rod 6 through the connecting plate 4. When the auxiliary block 7 drives the movable rod 3 to move, the movable rod 3 drives the sliding rod 6 to move through the connecting plate 4, and the sliding rod 6 drives the cleaning scraper 8 to move along the side wall of the channel 2 of the valve 1, thereby completing the cleaning of the side wall of the channel 2 of the valve 1.

[0026] The present utility model provides a clog - proof valve. By setting a cleaning scraper, impurities in the valve passage can be regularly cleaned, and there is no need to disassemble the valve for cleaning. By setting a chute, a sliding rod, a connecting plate and a movable rod, it is convenient to control the movement of the cleaning scraper, and at the same time, it does not occupy the space of the valve passage, ensuring the stable water flow through the valve. By setting threaded holes and threads on the movable rod, the movable rod can be prevented from being accidentally touched and thus unable to slide, ensuring the stability of the movable rod and extending its service life. The structure of the present utility model is simple and convenient to use. It can regularly clean the impurities in the valve passage, does not need to disassemble the valve for cleaning, is convenient to control the movement of the cleaning scraper, does not occupy the space of the valve passage, ensures the stable water flow through the valve, can prevent the movable rod from being accidentally touched and unable to slide, ensures the stability of the movable rod, and extends its service life.
