Due to the wave phenomenon of violent atmospheric precipitation, flow regulators are used in the rainwater sewage system. As a result of an increased grow of the water table, there are temporary hydraulic overloads formed. Owing to the use of hydrodynamic flow regulators, the value of maximal hydraulic intensity is decreased at the outflow. Flow regulators are used as discharge system upgrade in the hydraulic rainwater sewage system.
Flow regulators manufactured by us are characteristic for a catalogue choice proportional to indicators typical for a given sewage system. Varied flow through Reglar regulators is regulated by a calculated value of a coefficient limiting the liquid outflow.
Cone-shaped hydrodynamic regulators
Diagram of cone-shaped rotary regulator
In the cone-shaped rotary regulator, liquid flows to the device through an inlet port (1), placed in the larger cone base, owing to which rotary motion is generated and it is preserved within the entire length of the chamber (2) up to the outlet opening (3) in a narrower end of the truncated cone. In this motion, circular speed increases while approaching the cone axis, and owing to centrifugal force in the rotary chamber, pressure decreases in the direction of its axis in order to obtain ambient pressure on the surface of air core (4).
Generated air core exerts crucial influence on the effectiveness of choking operation of the device. The cone axis is generally deflected from the level with a certain angle, so that one axis forming the cone is horizontal for the purpose of self-dehydration of the device. The liquid sprayed at the outflow of the regulator forms a cone with γ angle.

Reglar cone-shaped flow regulators
It is possible to order cone-shaped regulators as per individual needs of a customer.
