It is easy for impurities in the fluid to enter the valve core in the valve, and it is easy for impurities to accumulate on the valve core, resulting in the valve core in the valve not closing tightly when closing, making the valve performance poor. Therefore, the utility model provides a valve with a filtering structure. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-5, a valve with a filtering structure, including a valve body 1, a filter screen 2 is overlapped on the inner wall of the valve body 1, a pull rod 3 is fixedly installed on the front side of the filter screen 2, and the number of the pull rods 3 is multiple, which is convenient for installing or removing the filter screen 2, and a limit plate 4 is fixedly installed on the rear side of the filter screen 2. A limit groove 5 is provided on the surface of the limit plate 4. The top and bottom of the valve body 1 are fixedly installed with a mounting plate 6, and a horizontal plate 7 is fixedly installed on the surface of the mounting plate 6. A movable plate 8 is slidably connected inside the horizontal plate 7, and the movable plate 8 is slidably connected to the valve body 1. An elastic component is provided on the surface of the movable plate 8, and the elastic component is connected to the horizontal plate 7. The inner wall of the movable plate 8 is fixedly installed with a limit block 11, and the elastic component includes a connecting plate 9 fixedly arranged on the surface of the movable plate 8. The opposite surface of the connecting plate 9 is fixedly installed with a spring 10, and the spring 10 is fixedly connected to the cross plate 7, so that the limit block 11 can be more conveniently inserted into the limit groove 5, thereby facilitating the limiting plate 4 to be limited. A slot 12 is provided on the right side of the movable plate 8, and a fixed plate 13 is fixedly installed on the right side of the mounting plate 6. The fixed plate 13 is L-shaped and is made of stainless steel, so that the fixed plate 13 has a higher structural strength, thereby facilitating the fixed plate 13 to be more durable. The inside of the fixed plate 13 A driving assembly is provided, and a plug plate 16 is provided inside the fixed plate 13 through the driving assembly. A guide assembly is provided on the rear side of the plug plate 16, and the guide assembly is connected to the fixed plate 13. The limit block 11 is plugged into the limit groove 5, and the plug plate 16 is plugged into the slot 12. When the fluid enters the valve body 1, the filter screen 2 can filter the impurities in the fluid, thereby preventing the impurities in the fluid from entering the valve core in the valve body 1, thereby facilitating the better use of the valve body 1. By cooperating with the driving assembly and the guide assembly, the plug plate 16 is separated from the slot 12. Pressing the elastic component makes the movable plate 8 and the limit block 11 approach each other, so that the limit block 11 is separated from the limit groove 5, and the filter screen 2 is taken out for cleaning. Then the cleaned filter screen 2 is placed into the valve body 1, and the movable plate 8 and the limit block 11 are moved away from each other by the elastic component, so that the limit block 11 is inserted into the limit groove 5. Through the coordinated use of the driving component and the guide component, the plug-in plate 16 is inserted into the slot 12, so that the filter screen 2 can be disassembled and assembled, thereby making it easier to disassemble and clean the filter screen 2, so that the filter screen 2 can better perform filtering work.

[0022] Specifically, the driving assembly includes a movable rod 14 threadedly arranged inside the fixed plate 13, a turntable 15 is fixedly installed on the right end of the movable rod 14, and the movable rod 14 is rotatably connected to the plug plate 16 to facilitate the movement of the plug plate 16, and the guide assembly includes a slider 17 fixedly arranged on the rear side of the plug plate 16, and a slide rail 18 is slidably connected to the surface of the slider 17, and the slide rail 18 is fixedly connected to the fixed plate 13 to facilitate guiding the movement of the plug plate 16. Through the coordinated use of the driving assembly and the guide assembly, the plug plate 16 can be more stably inserted into the slot 12, which facilitates the limiting of the movable plate 8, thereby facilitating the more stable installation of the filter screen 2.

[0023] During use: When the fluid enters the valve body 1, the impurities in the fluid can be filtered through the filter 2. When the filter 2 needs to be disassembled and cleaned, the turntable 15 is rotated to make the movable rod 14 move to the right while rotating, so that the plug plate 16 and the slider 17 move to the right along the slide rail 18 until the plug plate 16 is separated from the slot 12. The connecting plate 9 is pressed to compress the spring 10. At the same time, the movable plates 8 are moved closer to each other, so that the limit blocks 11 are moved closer to each other until the limit blocks 11 are separated from the limit slot 5. The pull rod 3 is pulled to remove the filter 2 from the valve body 1. After cleaning, the filter screen 2 is placed in the valve body 1 through the pull rod 3, and the connecting plate 9 is loosened. The force generated by the compression of the spring 10 makes the connecting plates 9 move away from each other, the movable plates 8 move away from each other, and the limit blocks 11 move away from each other, so that the limit blocks 11 are inserted into the limit groove 5 to limit the limit plate 4. Then, the turntable 15 is rotated in the opposite direction to make the movable rod 14 rotate and move to the left, so that the insert plate 16 and the slider 17 move to the left along the slide rail 18, so that the insert plate 16 is inserted into the slot 12 to limit the movable plate 8.

[0024] To sum up, in the valve with a filtering structure, when the fluid enters the valve body 1, the impurities in the fluid can be filtered through the filter screen 2, thereby preventing the impurities in the fluid from entering the valve core in the valve body 1, thereby facilitating better use of the valve body 1. By cooperating with the driving component and the guide component, the plug plate 16 is separated from the slot 12, and the elastic component is pressed to make the movable plate 8 and the limit block 11 approach each other, so that the limit block 11 is separated from the limit groove 5, and the filter screen 2 is taken out for cleaning. Subsequently, the cleaned filter screen 2 is placed in the valve body 1, and the elastic component is used to make the movable plate 8 and the limit block 11 move away from each other, so that the limit block 11 is inserted into the limit groove 5. By cooperating with the driving component and the guide component, the plug plate 16 is inserted into the slot 12, so that the filter screen 2 can be disassembled and assembled, thereby facilitating the disassembly and cleaning of the filter screen 2 more conveniently, thereby facilitating the filter screen 2 to better perform filtering work, thereby solving the problems raised in the above-mentioned background technology.
