Water inlet valve with instant pollution discharge function

The invention discloses a water inlet valve with an instant pollution discharge function, which comprises a valve body provided with a medium runner for a medium to circulate and a first channel and a second channel; the control assembly is arranged on the valve body and used for opening and closing the medium flow channel; the filtering structure is arranged on the valve body, and a medium enters from the first channel, sequentially flows through the control assembly and the filtering structure and then flows out from the second channel; and the pollution discharge part is arranged on the valve body and is used for being matched with the filtering structure and/or the medium flow channel to discharge impurities in the valve body. By limiting the relative position of the filtering structure and the control assembly, when impurities in a valve and a pipeline need to be cleaned, the impurities in the filtering structure and the pipeline can be discharged without closing a main valve or the control assembly of t
