MULTI-POSITION VORTEX GAS PRESSURE CONTROL Russian patent published in 2011 - IPC G05D16/00 G01L19/00 

FIELD: power industry.

SUBSTANCE: multi-position vortex gas pressure control includes supply and discharge gas pipelines, vortex tube, control assembly, and hot circuit channel. Control assembly represents slide valve consisting of cylinder in the wall of which the holes are made throughout the length, the number of which is equal to number of operating positions of control, which are equipped with dosing branch pipes, closed from above and from below with covers. Covers are equipped with gas supply branch pipe connected to supply gas line and with balancing branch pipe. Hollow plunger is arranged inside cylinder of slide valve. Elastic element is located inside plunger. Vortex tubes have finning of outer surface of housing and connected through cold tubes to dosing branch pipes of slide valve, and through hot tubes to outlet header. Header is connected through balancing pipe to balancing branch pipe, thus forming hot circuit channel, and to discharge gas line.

EFFECT: improving reliability and efficiency of operation of multi-position vortex gas pressure control.
