The flow stabilizing tank 10, the water inlet pipe 20, the water passing pipe 30 and the water discharging pipe 40 are connected in sequence. When equipment normally comes into use in this affair example, the water entering of municipal pipe network does not have negative pressure stationary flow jar 10, and the air in the jar flows out from combined type discharge valve 13 in a large number, and when the air was discharged, the floater was floated by water in the valve, and the transmission chock plug to closed position slowly closed the gas vent, stopped the exhaust, prevented out water. When the water flow in the steady flow tank 10 is normally conveyed, if a small amount of air is gathered in the valve inner channel to a certain extent, the water level in the valve is lowered, the floating ball is lowered along with the water level, and at the moment, the air is discharged from the air outlet hole. In the equipment normal operating engineering, when municipal pipe network water supply is not enough, when the downthehole rivers of municipal administration inlet tube were empty, or when the water pressure was less than atmospheric pressure in the stationary flow jar 10, the water level declined in the stationary flow jar 10, and the floater descends thereupon, drives the chock plug and opens, and the suction air makes and keeps atmospheric pressure in the stationary flow jar 10, is unlikely to produce the negative pressure to the municipal pipe network.
