The HYDROVEX® IHV Euro-type vortex flow regulators operate without moving parts, exclusively under the effects of the flow.
HYDROVEX® IHV Euro-type vortex flow regulators are designed to perform dynamic flow regulation. They find their application in Stormwater, Combined or Sanitary Sewers. They are installed at the outlet point of drains, retention tanks, Storm outfalls, etc.
The HYDROVEX® IHV Euro-type allows practical and easy flow regulation of sites that are otherwise difficult to manage. Some 5000 HYDROVEX® IHV regulators of all kinds are installed throughout the world. The fact that, until now, none of them have failed its task, confirms the exceptional reliability of the product.
Contrary to flow regulators in dry pits, wet well flow regulators do not require chambers separate from the storage area. These units can be mounted directly on the outlet wall of basins or the storage pipes.
Operation
The HYDROVEX® IHV Euro-type vortex flow regulator has a rigid hydrodynamic body without any moving parts. Water enters the vortex chamber through the tangential inlet pipe. In dry time flow conditions, the unit presents very open sections to the flow. The dry time flow is simply deviated in soft curves; the flow pattern here is a simple large area change of direction. In this flow mode, the vortex flow regulator presents virtually no resistance to the flow.
If the upstream head increases, air escapes from the vortex chamber. The conical vortex chamber creates a vortex flow pattern. High tangential velocities are formed, as well as a swirling core of air in the center. The air core blocks the major part of the outlet section. In this mode, the vortex regulator is an ideal hydraulic brake. The flow restriction is equivalent to an orifice plate with an open area up to 6 times smaller.
The vortex flow regulator in wet well is not accessible when there is water stored. For this reason, the unit requires an emergency bypass operated without any access to the unit. In case of blockage, the operators can pull the pull cord mounted on the unit’s cover crosspiece, release the cover attaches and pull the cover out of the well. This effectively opens a unit bypass where the trapped water can escape. After the water drains down from the wet well, the cover is re-installed with the crosspiece lock.
