FIELD: manufacturing technology.
SUBSTANCE: vortex pressure regulator comprises an in-tube spiral element disposed along the axis of a pipeline and fixed in a segment inserted into the pipeline, wherein a number of turns and a pitch of the turn of the spiral element depends on a target linear characteristic of the change in pressure drop depending on the mass flow through the pipeline segment and is determined by a target design operating mode, and the size of its through-section is not less than 40 % of the cross-sectional area of the pipeline. Spiral element can be fixed in the pipeline segment by means of a sleeve, cuff or by self-anchoring.
EFFECT: invention allows the use of the vortex flow principle to create a wide-flow pressure regulator of a simplified design that reduces the risks of hydrate formation.
