[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention discloses an anti-blocking control valve, including a valve body 1. A liquid inlet channel 2 is opened on the left side surface of the valve body 1, and a liquid outlet channel 3 is opened on the right side surface of the valve body 1. A valve seat 4 is arranged in the valve body 1 between the liquid inlet channel 2 and the liquid outlet channel 3, and the valve seat 4 connects the liquid inlet channel 2 and the liquid outlet channel 3. A valve cover 5 is installed on the upper surface of the valve body 1. A handle assembly 6 is arranged on the valve cover 5. A valve core 7 is fixedly installed on the lower surface of the handle assembly 6. The lower surface of the valve body 1 is fixedly installed with a fixed plate 9 through a locking bolt 8. Round holes 10 are opened on both the lower side wall of the valve body 1 corresponding to the valve seat 4 and the fixed plate 9. A rectangular box 11 is fixedly installed on the lower surface of the fixed plate 9, and the upper surface of the rectangular box 11 is an open structure. A first sealing mechanism 12 is arranged on the lower side wall of the rectangular box 11. A filter mechanism 13 is fixedly installed on the upper surface of the first sealing mechanism 12, and the filter mechanism 13 is attached to the lower surface of the valve seat 4. A second sealing mechanism 14 is arranged on the right side surface of the rectangular box 11. A monitoring mechanism 15 is arranged between the front side surface of the valve body 1 and the front side surface of the rectangular box 11.

[0019] Specifically, a rubber sealing ring 16 is fixedly installed between the upper surface of the fixed plate 9 and the lower surface of the valve body 1.

[0020] In this implementation scheme, the rubber sealing ring 16 makes the sealing effect between the upper surface of the fixed plate 9 and the lower surface of the valve body 1 better.

[0021] Specifically, the first sealing mechanism 12 includes an electric linear module 121, a cross 122, a first plug 123, and a through hole 124. The electric linear module 121 is fixedly installed on the lower side wall of the rectangular box 11. A cross 122 is fixedly installed on the outer surface of the slide of the electric linear module 121, and the side surface of the cross 122 is movably attached to the inner wall of the rectangular box 11. A first plug 123 is fixedly installed on the upper surface of the cross 122, and a through hole 124 is formed in the first plug 123.

[0022] In this embodiment, the slide of the electric linear module 121 drives the cross 122 to move upward along the inner wall of the rectangular box 11, so that the cross 122 drives the first plug 123 to move upward, and the first plug 123 seals the round hole 10. The through hole 124 allows the screw rod of the electric linear module 121 to be installed and rotated.

[0023] Specifically, the filtering mechanism 13 includes a bearing assembly 131, a mounting plate 132, turbine blades 133, a support rod 134, a filter mesh plate 135, a fixing rod 136, and a scraper 137. The bearing assembly 131 is installed on the upper surface of the screw rod of the electric linear module 121 through the mounting plate 132. Turbine blades 133 are fixedly installed on the outer surface of the bearing assembly 131. A filter mesh plate 135 is installed on the upper surface of the bearing assembly 131 through a support rod 134. The upper surface of the filter mesh plate 135 is attached to the lower surface of the valve seat 4. A scraper 137 is installed on the upper surface of the turbine blades 133 through a fixing rod 136, and the upper surface of the scraper 137 is movably attached to the lower surface of the filter mesh plate 135.

[0024] In this embodiment, the mounting plate 132 fixes the bearing assembly 131. The support rod 134 on the upper surface of the bearing assembly 131 installs the filter mesh plate 135. The filter mesh plate 135 filters impurities in the liquid entering the valve seat 4. The bearing assembly 131 enables the turbine blades 133 to rotate. The turbine blades 133 are driven by the liquid flowing into the liquid inlet channel 2 to rotate, so that the turbine blades 133 drive the scraper 137 to rotate through the fixing rod 136, and the scraper 137 cleans the impurities on the lower surface of the filter mesh plate 135 to prevent the filter mesh plate 135 from being blocked.

[0025] Specifically, the second sealing mechanism 14 includes an electric telescopic rod 141, a connecting plate 142, a second plug 143, and a slag discharge hole 144. The electric telescopic rod 141 is fixedly installed on the right side surface of the rectangular box 11, and there are two electric telescopic rods 141 arranged front and back. A connecting plate 142 is fixedly installed between the right side surfaces of the output shafts of the electric telescopic rods 141. A second plug 143 is fixedly installed on the left side surface of the connecting plate 142. A slag discharge hole 144 is formed in the right side wall of the rectangular box 11 corresponding to the second plug 143.

[0026] In this implementation scheme, the output shaft of the electric telescopic rod 141 drives the connecting plate 142 to move to the right, causing the connecting plate 142 to drive the second plug 143 to move to the right. The second plug 143 is separated from the slag discharge hole 144, enabling the impurities in the rectangular box 11 to flow out through the slag discharge hole 144.

[0027] Specifically, the monitoring mechanism 15 includes a controller 151 and a water flow rate sensor 152. The controller 151 is installed on the front side of the rectangular box 11, and the water flow rate sensor 152 is installed on the front side of the valve body 1 corresponding to the liquid inlet channel 2 and the liquid outlet channel 3.

[0028] In this implementation scheme, the controller 151 monitors the water flow rate through the water flow rate sensor 152 in the liquid inlet channel 2 and the liquid outlet channel 3. When the difference between the flow rate in the liquid outlet channel 3 and the flow rate in the liquid inlet channel 2 is greater than the set value, it indicates that a blockage has occurred. The controller 151 activates the first sealing mechanism 12 and the second sealing mechanism 14 to discharge the slag.

[0029] During use, the mounting plate 132 in the filtering mechanism 13 fixes the bearing assembly 131. The support rod 134 on the upper surface of the bearing assembly 131 mounts the filter mesh plate 135. The filter mesh plate 135 filters the impurities in the liquid entering the valve seat 4. The bearing assembly 131 enables the turbine blade 133 to rotate. The turbine blade 133 is driven to rotate by the liquid flowing into the liquid inlet channel 2, causing the turbine blade 133 to drive the scraper 137 to rotate through the fixing rod 136. The scraper 137 cleans the impurities on the lower surface of the filter mesh plate 135 to prevent the filter mesh plate 135 from being blocked. Through the controller 151 in the monitoring mechanism 15, the water flow rate is monitored through the water flow rate sensor 152 in the liquid inlet channel 2 and the liquid outlet channel 3. When the difference between the flow rate in the liquid outlet channel 3 and the flow rate in the liquid inlet channel 2 is greater than the set value, it indicates that a blockage has occurred. The controller 151 makes the slide of the electric linear module 121 in the first sealing mechanism 12 drive the cross 122 to move upward along the inner wall of the rectangular box 11, causing the cross 122 to drive the first plug 123 to move upward. The first plug 123 seals the round hole 10. At this time, the liquid in the valve body 1 will not flow into the rectangular box 11. Then, the output shaft of the electric telescopic rod 141 in the second sealing mechanism 14 drives the connecting plate 142 to move to the right, causing the connecting plate 142 to drive the second plug 143 to move to the right. The second plug 143 is separated from the slag discharge hole 144, enabling the impurities in the rectangular box 11 to flow out through the slag discharge hole 144 to achieve the effect of discharging the slag. After the slag discharge is completed, the second sealing mechanism 14 seals to seal the slag discharge hole 144 on the right side wall of the rectangular box 11. Then, the first sealing mechanism 12 seals, and the first plug 123 returns to the round hole 10. In this way, the impurities scraped off by the filter mesh plate 135 can fall into the rectangular box 11, and the filtered impurities can be discharged without disassembling or closing the control valve, effectively avoiding blockage of the control valve and facilitating use.

[0030] In summary, the anti-clogging control valve can filter impurities in the liquid and clean the filtering mechanism 13, so that the impurities fall into the rectangular box 11, and the filtered impurities can be discharged without disassembling or closing the control valve, which is beneficial to use.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
