[0024] Reference Figure 1 , Figure 3 and Figure 6 In order to facilitate the removal and cleaning of the filter plate 11 from the valve body 1, the drain pipe 4 is perpendicular to the water inlet and outlet of the valve body 1, and a plurality of equidistant annular thread grooves 21 are axially provided on the end face of the drain pipe 4. A plurality of countersunk holes 23 adapted to the thread grooves 21 are axially penetrated on the outside of the cover plate 5, and a first hexagon socket bolt 6 is movably sleeved in each countersunk hole 23. The end of the first hexagon socket bolt 6 extends into the thread groove 21 and is threadedly connected to the thread groove 21. A rubber sealing ring 22 is commonly abutted between the cover plate 5 and the drain pipe 4.

When the cleaning is completed and it is installed back into the valve body 1, lift the block 8 on one side of the sewage pipe 4 upward again so that the block 8 is retracted into the groove 14, and then screw the external threaded tube 12 into the threaded hole 10 in the valve ball 7 until the end of the threaded tube abuts against the other block 8, and then loosen the block 8 at the sewage pipe 4, and the spring 15 in the compressed state is reset. When the spring 15 is reset, the block 8 is pushed out of the groove 14 and abuts against the end of the external threaded tube 12, and then the cover plate 5 is passed through the first hexagon socket bolt 6 to close the sewage pipe 4, and then the valve body 1 is rotated open by the valve stem 3, that is, the center of the threaded hole 10 and the center of the waterway of the valve body 1 are located on the same center line.
