Non -maintaining high pressure solution gas release suitable for air supporting technology

The utility model relates to a water treatment facilities especially relates to a non -maintaining high pressure solution gas release suitable for air supporting technology. The device comprises manual plunger valve, circulating water diaphragm valve, manometer, pneumatic ball valve, through adjusting the size and the dough stability that the gas bubble is dissolved in the control of manual plunger valve and circulating water diaphragm valve. The advantage of this device does: it is little to dissolve gas outgas process noise, and the bubble of production is fine, density is big, and it is even to dissolve gas, and air supporting is effectual. The problem of traditional dissolved air releaser easily block up, and maintain, overhaul complicatedly is solved.
