[0057] In use, the municipal water supply flow enters from the water inlet 102 of the water supply pipeline 101. The water pressure moves the sealing plate 202e out of the first positioning hole 202a. The upward movement of the sealing plate 202e drives the sliding rod 202g to move, and in turn drives the moving plate 202h to move upward and press the spring 202i. The water pressure is greater than the elastic force of the spring 202i. The upward movement of the sealing plate 202e drives the connecting rod 202d to move, and in turn drives the filter plate 202c to be connected with the second positioning hole 202b. At this time, the water flow is filtered by the filter plate 202c and discharged from the water outlet 103. When the water flow stops conveying, the spring 202i is not water pressure. After the spring 202i is squeezed, the spring 202i drives the moving plate 202h to reset, and in turn drives the sealing plate 202e to reset and be connected with the first positioning hole 202a, so that the water supply pipeline 101 is sealed, and the water flow cannot flow backward. Finally, the threaded ring 203f is rotated by the rotating plate 203d, and the dismounting pipe 203a is taken out of the blowdown pipe 105, and the filtered impurities are cleaned.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
