FIELD: machine building.
SUBSTANCE: suppressor is intended for reduction of hydrodynamic noise level emitted by liquid flow in pipelines. In closed cavity of hydrodynamic noise suppressor, pliable element is installed, for instance, hose, ends of which are connected to nipples withdrawn outside casing, pliable element is filled with air of pressure equal to maximum operating pressure of liquid, and free space of cavity is filled with loose or deformable substance, for instance, sand or rubber balls with diameter of up to 5 mm.
EFFECT: lower level of hydrodynamic noise level downwards hydrodynamic noise suppressor at all working modes by pressure, and also exclusion of necessity for adjustment and control.
