Hydrobrake Hydro international - animated info graphic

Описание: Under low flow conditions (during the pre-initiation phase), the Hydro-Brake® Flow Control behaves like a traditional orifice with an aperture cross-sectional area similar to that of the Hydro-Brake® Flow Control outlet aperture.

The flow is gentle, with minimal turbulence inside the volute of the Hydro-Brake® Flow Control or the outlet pipe.
As the acting head increases and the unit is covered by water, the Hydro-Brake® Flow Control enters the post-initiation phase. Because of the tangential inlet flow and the fixed geometry of the unit, a vortex flow regime develops in the volute and outlet pipe.

An aerated core, accompanied by substantial backpressure, effectively chokes the flow through the outlet aperture.
