[0024] As Figures 1-6 shown, the safe, reliable, anti-clogging and wear-resistant hydraulic valve provided in this embodiment includes a valve body 1 and a liquid inlet pipe 2 installed on one side of the valve body 1. A liquid discharge pipe 3 is installed on the other side of the valve body 1. A filter screen 14 is installed inside the liquid discharge pipe 3. A valve cover 4 is installed on the valve body 1. A support plate 5 is installed on the top of the valve cover 4. A motor 6 is installed on the support plate 5. A connecting component is installed at the output end of the motor 6. An adjusting pipe 9 is installed at the bottom of the connecting component. A bottom plate 15 is slidably installed on the adjusting pipe 9. A cleaning brush plate 17 is installed on the bottom plate 15. A cleaning brush 19 is installed on the cleaning brush plate 17. By setting the cleaning brush 19 and sliding the cleaning brush 19, the cleaning brush 19 cleans the filter screen 14 to prevent the hydraulic valve from being clogged due to the blockage of the filter screen 14. By sliding the second sealing plate 22 and the cleaning brush 19, the impurities in the hydraulic valve can be discharged to avoid the accumulation of impurities in the hydraulic valve. By setting the support plate 5, the support plate 5 starts to drive the adjusting pipe 9 to rotate, and the liquid flow rate can be controlled.

[0025] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, the connecting component includes a connecting plate 7 and a first connecting rod 8. The connecting plate 7 is installed at the output end of the motor 6. The bottom of the connecting plate 7 is connected to the adjusting pipe 9 through the first connecting rod 8. By setting the connecting plate 7 and the first connecting rod 8 to cooperate with each other, when the support plate 5 starts to drive the connecting plate 7 to rotate, the connecting plate 7 and the first connecting rod 8 cooperate with each other to drive the adjusting pipe 9 to rotate to adjust the liquid flow rate. A second connecting rod 18 is installed on the cleaning brush plate 17. The top of the second connecting rod 18 is installed with a top plate 10. A first sealing plate 13 is installed on the top plate 10. A grip 11 is installed on the top plate 10. An anti-slip pad is installed on the grip 11. By setting the top plate 10 and the first sealing plate 13, the top of the adjusting pipe 9 can be sealed. By setting the grip 11, pulling the grip 11 drives the top plate 10 to move, and then drives the second connecting rod 18, the bottom plate 15 and the cleaning brush 19 to move to clean the filter screen 14. By setting the anti-slip pad, the friction of the grip 11 can be increased. A second sealing plate 22 is installed on the bottom plate 15. A baffle 16 is installed on the top of the bottom plate 15.

A rotating block 20 is installed at the bottom of the adjusting pipe 9, and a rotating groove that cooperates with the rotating block 20 is provided on the valve body 1. By setting the rotating block 20 to be rotatably connected with the rotating groove, the adjusting pipe 9 can be rotated on the valve body 1, and thus the flow rate of the liquid can be adjusted. A plurality of rotating cavities are provided in the rotating block 20, and a ball 21 is rotatably installed inside the rotating cavity. By setting the ball 21, the frictional force of the rotation of the rotating block 20 can be reduced.

[0028] Step 1: The motor 6 starts to drive the connecting plate 7 to rotate in cooperation with the first connecting rod 8, and then drives the adjusting pipe 9 to rotate to adjust the flow rate of the liquid;

[0029] Step 2: When the filter screen 14 needs to be cleaned, pull the top plate 10 to slide the cleaning brush 19, and then clean the filter screen 14. The impurities generated by the cleaning fall on the bottom plate 15. When the top plate 10 and the bottom plate 15 slide, the impurities are discharged from the valve body 1 to prevent the valve body 1 from being blocked.

[0030] In summary, in this embodiment, the wear-resistant hydraulic valve with safety, reliability and anti-blocking according to this embodiment, by setting the cleaning brush 19 and sliding the cleaning brush 19, the cleaning brush 19 cleans the filter screen 14 to avoid the blockage of the hydraulic valve caused by the blockage of the filter screen 14. By sliding the second sealing plate 22 and the cleaning brush 19, the impurities in the hydraulic valve can be discharged to avoid the accumulation of impurities in the hydraulic valve. By setting the support plate 5, the support plate 5 starts to drive the adjusting pipe 9 to rotate, which can control the liquid flow rate. By setting the connecting plate 7 and the first connecting rod 8 to cooperate with each other, when the support plate 5 starts to drive the connecting plate 7 to rotate, the connecting plate 7 and the first connecting rod 8 cooperate with each other to drive the adjusting pipe 9 to rotate to adjust the liquid flow rate. By setting the top plate 10 and the first sealing plate 13, the top of the adjusting pipe 9 can be sealed. By setting the grip 11 and pulling the grip 11, the top plate 10 is driven to move, and then the second connecting rod 18, the bottom plate 15 and the cleaning brush 19 are driven to move to clean the filter screen 14. By setting the anti-slip pad, the friction of the grip 11 can be increased. By setting the baffle 16, it can prevent impurities from entering the liquid inlet pipe 2 when the bottom plate 15 slides. By setting the limiting block 12 to be engaged with the limiting groove, when the motor 6 starts to drive the adjusting pipe 9 and the top plate 10 to move, the liquid flow rate can be adjusted. By setting the rotating block 20 to be rotatably connected with the rotating groove, the adjusting pipe 9 can rotate on the valve body 1, and thus the liquid flow rate can be adjusted. By setting the ball 21, the friction of the rotating block 20 during rotation can be reduced.
