working principle:

The grooved butterfly valve of the present invention is fixedly installed on the pipeline. By rotating the handle 5, the vortex drives the valve stem 6 to rotate. The rotation of the valve stem 6 drives the butterfly plate 7 to rotate, so that the butterfly plate 7 and the sealing structure 8 are offset. move, thereby opening the butterfly plate 7, and then the fluid will move from the right side to the left side of the valve body 1 under the action of pressure. The fluid passes through the filter plate 9, and the sediment and impurities in the fluid are filtered by the filter plate 9 and deposited on the valve body. 1. In the drain hole 11 provided at the bottom, the filtered sediment is temporarily stored in the drain hole 11. By regularly opening the sealing plug 12 below the drain hole 11, the sediment in the sedimentation tank can be discharged from the drain hole 11. The filter plate 9 achieves the effect of filtering the sediment in the fluid, preventing the sediment from causing wear on the disc, resulting in weakening of the sealing effect and resulting in leakage; and at the same time preventing the sediment from wearing the sealing surface, making it difficult to open and close the butterfly valve.

At the same time, cleaning components are provided on both sides of the filter plate 9. After long-term use, when the filter holes on the filter plate 9 are blocked by sediment and impurities, the valve body 1 can be removed by closing the drainage upstream of the pipe. The seal 103 on the lower end connecting pipe 102 then connects the high-pressure water pipeline with the connecting pipe 102. The high-pressure water flow passes through the connecting pipe 102 and enters the water channel 104 set in the center of the cleaning ring 101, and then the high-pressure water flow in the channel 104 is passed through. The water spray holes 105 arranged obliquely on the inner diameter surface of the cleaning ring 101 are sprayed onto the filter plate 9 to wash away the sediment and impurities blocked on the filter plate 9 so that the sediment and impurities on the filter plate 9 fall from the filter plate 9 into the drain hole 11 below, and discharge the washed sediment and impurities to the outside of the valve body 1 through the drain hole 11; there is no need to disassemble the valve body 1 to clean the filter plate 9, thereby achieving quick and convenient cleaning of the filter plate 9 Effect.

Although the present disclosure has been described in detail with reference to exemplary embodiments, the present disclosure is not limited thereto, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the scope of the present disclosure.
