The flush valve has in its inlet pipe of its main body a turnable knob, a hollow pipe-like filtering net provided on one side of an adjusting through hole opposite to an adjusting knob, and an elastic element and a pad provided inside the filtering net, water pressure will push away the pad and compress the elastic element to get into the filtering net for filtering out impurity in water and then get into the main body, when the valve is closed, the pad will cover the adjusting through hole by restoring force of the elastic element and the reversing water flow, the reversing hammering created by abrupt stopping of water will be absorbed by the pad, its pipe structure can thus be prevented from damage and leaking, the filtering net can be dismounted for cleansing and maintenance easily.
