[0028] According to the overall structure of the device, when the valve body 1 is in operation, the hand wheel 4 is rotated to rotate the screw 3 in the threaded barrel on the bracket so that the valve stem at the bottom of the screw 3 can rise or fall, so that the valve disc 6 presses the sealing ring 8 of the limit ring 7 to close and stop draining, or the valve disc 6 leaves the sealing ring 8 of the limit ring 7 to drain. The sealing performance of the valve stem at the bottom of the screw 3 and the valve seat 2 is better through the arrangement of the packing 9 and the packing gland 10. When the valve body 1 is draining, the sewage will first pass through the filter screen 13 on the inner wall of the mounting ring 21, and then be discharged from the other end of the valve body 1, so that some dirt in the sewage can be filtered and limited by the filter screen 13 and is not easy to adhere to the valve disc 6. After the filter screen 13 has filtered and limited the dirt for a long time, the sealing plug of the water inlet pipe 11 and the sewage pipe 12 are opened. The sealing cover is opened, and the cleaning water is continuously passed into the water inlet pipe 11, and the valve disc 6 presses the sealing ring 8 of the limit ring 7, so that the cleaning water can flow from one side of the filter screen 13 to the other side, and the dirt on the filter screen 13 is flushed, so that the dirt can be discharged from the drain pipe 12 with the water flow for cleaning. During cleaning, the collar 18 is rotated in the annular guide groove 17 by the handle 20, so that the magnetic block 19 rotates along the outer surface of the valve body 1. Due to the adsorption force of the magnetic block 19 on the magnetic block 16, the magnetic block 16 will also rotate with the magnetic block 19, so that the brush 15 rotates on the shaft seat 14, and the bristles of the brush 15 continuously brush the filter screen 13, so that the dirt can be loosened on the surface of the filter screen 13, so that it can be more easily taken away by the water flow for cleaning.

[0030] By providing the limit ring 7, sealing ring 8, packing 9 and packing gland 10, when the valve disc 6 is pressed down to the limit ring 7, one end of the valve body 1 can no longer discharge sewage, and the provision of the sealing ring 8 increases the sealing between the valve disc 6 and the limit ring 7, and the packing 9 and the packing gland 10 increase the sealing between the valve seat 2 and the valve stem on the bottom surface of the screw 3.
[0031] like Figure 1-2As shown, the dirt limiting assembly includes a mounting ring 21 and a filter screen 13, a mounting ring 21 is fixedly mounted on one end of the inner wall of the valve body 1, a filter screen 13 is fixedly mounted on the inner wall of the mounting ring 21, a cleaning auxiliary assembly is arranged on the side of the filter screen 13, and the cleaning assembly includes a water inlet pipe 11 and a sewage pipe 12, the upper end of the arc surface of the valve body 1 is located on one side of the filter screen 13 and is penetrated by a water inlet, and the water inlet pipe 11 is fixedly mounted on the inner wall of the water inlet, a thread is arranged on the inner wall of the water inlet pipe 11, and a sealing plug is connected with the thread, the lower end of the arc surface of the valve body 1 is located on the other side of the filter screen 13 and is penetrated by a sewage outlet, and a sewage outlet is fixedly mounted on the inner wall of the sewage outlet, and the outer surface of the sewage outlet is provided with a thread, and a sealing cover is connected with the thread.
[0032] By setting the mounting ring 21, filter screen 13, water inlet pipe 11 and sewage pipe 12, when the valve body 1 is discharging sewage, the sewage will first pass through the filter screen 13 on the inner wall of the mounting ring 21, and then be discharged from the other end of the valve body 1, so that some dirt in the sewage can be filtered and limited by the filter screen 13, and is not easy to adhere to the valve disc 6. After the filter screen 13 has filtered and limited the dirt for a long time, by opening the sealing plug of the water inlet pipe 11 and the sealing cover of the sewage pipe 12, and continuously passing the cleaning water into the water inlet pipe 11, and making the valve disc 6 press the sealing ring 8 of the limiting ring 7, the cleaning water can flow from one side of the filter screen 13 to the other side, flush the dirt on the filter screen 13, so that the dirt can follow the water flow and finally be discharged from the sewage pipe 12 for cleaning.
[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning auxiliary component includes a shaft seat 14, a brush 15 and a magnet 16. The shaft seat 14 is fixedly installed on the middle end of the side of the filter 13. The inner wall of the shaft seat 14 is sleeved with a rotating shaft, and the brush 15 is fixedly installed on one end of the rotating shaft.

[0035] Working principle: When the valve body 1 is in operation, the hand wheel 4 is rotated to rotate the screw 3 in the threaded barrel on the bracket so that the valve stem on the bottom of the screw 3 can rise or fall, so that the valve flap 6 presses the sealing ring 8 of the limit ring 7 to close and stop sewage discharge, or the valve flap 6 leaves the sealing ring 8 of the limit ring 7 to discharge sewage. When the valve body 1 discharges sewage, the sewage will first pass through the filter 13 on the inner wall of the mounting ring 21, and then be discharged from the other end of the valve body 1, so that some dirt in the sewage can be filtered and limited by the filter 13. After the filter 13 has filtered the limited dirt for a long time, the sealing plug of the water inlet pipe 11 and the sealing cover of the sewage discharge pipe 12 are opened, and the cleaning water is kept Continue to pass water into the water inlet pipe 11, and make the valve disc 6 press the sealing ring 8 of the limit ring 7, so that the cleaning water can flow from one side of the filter screen 13 to the other side, flush the dirt on the filter screen 13, so that the dirt can be discharged from the drain pipe 12 with the water flow for cleaning. During cleaning, the ring 18 is rotated in the annular guide groove 17 by the handle 20, so that the second magnet 19 rotates along the outer surface of the valve body 1. Due to the adsorption force of the second magnet 19 on the first magnet 16, the first magnet 16 will also rotate with the second magnet 19, so that the brush 15 rotates on the second shaft seat 14, so that the bristles of the brush 15 continuously brush the filter screen 13.
