Weir air chamber, and positioned in the both sides of outlet pipe, its section is funnel shaped, is directly connected to Air Weir air chamber, it is described enter outlet
Manage as the direct UNICOM's Air Weir air chamber of T font pipelines, described T fonts pipeline one end connects intake valve, other end connection air outlet valve,
Pressure transmitter is included between intake valve and air outlet valve, the outlet pipe adopts the vertical UNICOM's Air Weir air chamber of reverse U shape, level
Through body of wall, and the total outlet pipe UNICOM with horizontal direction.
The shape of the Air Weir air chamber can select annular, rectangle or yi word pattern according to the pond shape of sedimentation tank：
Specifically, when sedimentation tank is circle, select Air Weir air chamber and can adopt ring-shaped air chamber；When sedimentation tank rectangle, air
Weir air chamber can adopt rectangle or yi word pattern air chamber；
The water inlet selects annular, rectangle or yi word pattern according to the shape of Air Weir air chamber：
Specifically, when Air Weir air chamber is annular, water inlet is using annular；When Air Weir air chamber is rectangle, water inlet
Mouth is using annular；When Air Weir air chamber is yi word pattern, water inlet adopts yi word pattern；
The beneficial effects of the utility model：This utility model controls the dress of pond interval water outlet using air pressure variations
Put, the purpose for being controlled to reach draining and stop draining by keying of the automatic control system to trachea valve, Air Weir are adopted
The mode of water outlet under liquid level, in being particularly suited for having the pond of aeration, prevents scum silica frost from flowing out with current, and avoids traditional water outlet
Weir is used for caused short stream of bad institute etc. of constructing, and breather is set up on outfall sewer effectively prevents siphon.
