Abstract
A siphon weir having a downwardly directed inlet port and a lower lying outlet port (18) on the downstream side connected with it by means of an approximately S-shaped siphon line (13) contains a ventilating mechanism for improving the regulating behavior. The ventilating mechanism is preferably constructed as a linear, sloping ventilating pipe (46), which is led out of the interior of the container to be regulated through the rising leg of the siphon line (13) and issues below the siphon top in the downwardly leading falling leg of siphon line (13). A diverter (28) for floating material can be mounted on the upper end of ventilating pipe (46).
Claims17
A siphon weir for guiding flow of liquid from an inlet on an upstream side of the siphon weir within a container wall to an outlet on a downstream side of the siphon weir outside the container wall, comprising:
- downwardly directed means defining an inlet port to be arranged at the upstream side, the inlet port being connected to a siphon line for the liquid leading along a rising branch from the inlet port, and over a siphon top positioned higher than the inlet port, the siphon line leading further from the siphon top along a falling leg to an outlet port positioned lower than the inlet port, the outlet port to be arranged on the downstream side of the siphon weir;
- and,
- a ventilation mechanism for ventilating an interior of the siphon line as a function of a liquid level at the upstream side, the ventilating mechanism having at least one ventilating pipe, with one end issuing into the siphon line downstream of the siphon top, the ventilating pipe having a suction opening at an upper end positioned on the upstream side of the siphon top, roughly level with the siphon top.
