PRESSURE PULSATIONS DAMPER Russian patent published in 2016 - IPC F16L55/04 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to devices for pressure pulsations damping and can be used in pipeline systems of various branches of national economy, in particular, in flow rate measurement. Damper contains in a disassembled body a perforated insert and a conical chamber. Perforated insert is made in the form of two uniformly perforated plates arranged at the inlet and the outlet of the conical chamber with the total free cross-section at outlet holes of 55±8 % of the area of the plates, the perforation is made as convergent holes, before the first upstream the partial flow plate there is a cylindrical chamber installed on flange joints, in the lower generatrix of which there is a tangential inlet of the separated flow.

EFFECT: device enables to stabilize and uniformly distribute pressure of the flow along the discharge pressure multipipe beam.
