Abstract

The invention discloses a carbon dioxide beverage and beer pop can filling valve, which comprises an annular material tank. Backpressure gas is filled above materials in the annular material tank; the bottom of the annular material tank is provided with a valve body; a valve seat is arranged at the bottom of the valve body; a valve rod is arranged in the annular material tank; a fit surface is formed between the bottom end of the valve rod and the valve seat; a spring is arranged between the outer wall of the valve rod and the inner wall of the valve body; a filling seal cover is arranged on the outer wall of the valve body and can slide along the outer wall; and a backpressure channel for inputting the backpressure gas into pop cans to be filled and a control mechanism thereof, and a pressure relief channel for blowing down the gas in the pop cans to be filled and a control mechanism thereof are arranged in the annular material tank and the valve body. By arranging the backpressure gas and the backpressure channel, the backpressure gas blows the interiors of the pop cans before filling, and oxygen increase is reduced; and backpressure is applied, so that the pressure inside the pop cans is absolutely equal to the pressure of the backpressure gas during filling, liquid level fluctuation caused by stable state differential pressure is eliminated, and complete equipressure filling and stable filling are realized.
