[0034] Referring to Figure 1 , Figure 2 , Figure 5, installation components are provided on the left and right sides inside the valve top 2. The installation components are used to connect the valve top 2 and the valve cover 3. The installation components include a push rod 7. The push rod 7 is slidably connected inside the valve top 2. One end of the push rod 7 is fixedly connected with a cross plate 8. The push rod 7 slides inside the valve top 2 and can drive the cross plate 8 to move because it is fixedly connected with the cross plate 8. The other end of the push rod 7 is fixedly connected with a push block 6. The push block 6 is disc-shaped, which can facilitate force application to control the movement of the push rod 7. Rotating rods 9 are rotatably connected to the front and rear sides of the cross plate 8. One end of each of the two rotating rods 9 away from the cross plate 8 is rotatably connected with a connecting block 10.

When the installation rods 5 are completely inserted into the valve top 2, the bottom of the valve cover 3 will contact the top of the valve top 2, thus completing the installation. Support rods 12 are fixedly connected to the front and rear sides inside the valve top 2. The two clamping blocks 11 are respectively slidably connected to the outer circumferences of the two support rods 12. The support rods 12 are mainly used to guide the movement of the clamping blocks 11. Slots 16 are provided on the front and rear sides of the installation rods 5. The opposite sides of the two clamping blocks 11 are respectively slidably connected inside the two slots 16. The slots 16 are used in cooperation with the clamping blocks 11. After the clamping blocks 11 are inserted into the slots 16, the installation rods 5 can be limited.

[0035] Refer to Figure 3 - Figure 4, a connection component is provided inside the assembly block 19. The connection component is used to connect the assembly block 19 and the mounting block 25. The assembly block 19 can be inserted into the mounting block 25, so that the filter plate 17 is completed for installation. The connection component includes a connecting rod 21. The connecting rod 21 is slidably connected inside the assembly block 19. A limiting plate 23 is fixedly connected to the bottom of the assembly block 19. The connecting rod 21 slides inside the assembly block 19 and is connected to the limiting plate 23. When the connecting rod 21 moves, it can drive the limiting plate 23 to move together. A second spring 22 is fixedly connected to the top of the limiting plate 23. The second spring 22 is sleeved on the outer periphery of the connecting rod 21. The second spring 22 is used to provide elastic support. A plug 24 is fixedly connected to the bottom of the limiting plate 23. The plug 24 is used to insert into the inside of the mounting block 25, so as to complete the connection between the mounting block 25 and the assembly block 19. A dial block 20 is fixedly connected to the top of the connecting rod 21. The dial block 20 is used to facilitate the movement of the connecting rod 21.

[0036] Working principle: When it is necessary to disassemble the valve top 2 and the valve cover 3 to repair the inside of the valve body 1, by pressing the push block 6, the push block 6 drives the push rod 7 to control the movement of the cross plate 8. When the cross plate 8 moves, the connecting plates 13 on the upper and lower sides of the cross plate 8 respectively stretch the two first springs 14, and the two rotating rods 9 rotate in opposite directions. At this time, the two connecting blocks 10 will drive the two clamping blocks 11 to move in opposite directions along the two support rods 12. After the two clamping blocks 11 slide out of the clamping grooves 16 inside the mounting rod 5, the mounting rod 5 loses the restriction of the clamping blocks 11, so that the valve top 2 and the valve cover 3 can be separated;

[0037] When the valve body 1 is connected to the pipeline for water flow, the impurities in the water will be filtered through the filter plate 17. When the water flow impacts the filter plate 17, the filter plate 17 will drive the assembly block 19 to move together. Since the assembly block 19 is connected to the dial block 20, the dial block 20 will drive the connecting rod 26 to move together, and then drive the first extrusion block 27 to move, so that the first extrusion block 27 controls the two second extrusion blocks 28 to move in opposite directions along the guide rod 30, and then extrude the compression spring 29 to buffer and absorb the impact force, so as to extend the service life of the filter plate 17;

[0038] When it is necessary to disassemble the filter plate 17, the dial block 20 is pulled upward. The dial block 20 drives the connecting rod 21 to move together. The connecting rod 21 drives the limiting plate 23 to move together, so that the limiting plate 23 moves upward to compress the second spring 22. After the plug 24 slides out of the mounting block 25, the filter plate 17 can be taken out through the handle 18. When installing, the dial block 20 is pulled correspondingly, so that the mounting block 25 is inserted into the assembly block 19. Then the dial block 20 can be released. The second spring 22 loses pressure and will reset to generate a thrust to push the limiting plate 23 to move, so that the plug 24 slides into the mounting block 25, and then the assembly block 19 and the mounting block 25 are fixed, thus completing the installation of the filter plate 17.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
