CONSTITUTION: A discharge valve for mixing and filling(1) comprises a housing(10) which includes a gunpowder inlet port(11) and a gunpowder outlet(12), a valve shaft(20) which moves along the central axis line in straight line within the housing, and a bellows(30) which is arranged to be separated from the outer circumference of the valve shaft. In one end of the valve shaft, a plug(21) which is in contact with a vent located in a scrambler(50) is installed. The other end is combined with a boss portion(22). One end of the bellows comes in contact with the plug, and the other end comes in contact with the boss portion. O-ring(28) is combined with the outer circumference of the boss portion or the plug in order to prevent inflow of the gunpowder. The bellows is formed with polytetrafluoroethylene material.
