PRESSURE REGULATOR Russian patent published in 2004 - IPC

Abstract RU 2237918 C1

FIELD: gas industry.

SUBSTANCE: regulator has supplying pipeline connected with the controlled tangential nozzle which is in communication with the cylinder for temperature separation and with discharging pipeline through an aperture. The discharging pipeline is connected with the pilot device. The screw passage, which provides the positive feedback via the hot circuit, is interposed between the supplying pipeline and cylinder for temperature separation. The screw passage is connected with the nozzle adjustable for height and providing critical velocity at the nozzle exit. The cylinder for temperature separation is closed by deceleration chamber and has pipe cross with profiled blades which smoothly straightens the flow and device for by-passing the hot gas downstream of the pipe cross to the center of the cold vortex at the axis of the cylinder for temperature separation. According to the second variant, the cylinder for temperature separation is made of self-evacuating vortex pipe. The positive feedback through the hot circuit is provided by the pipe for by-passing the hot gas to the axial zone of the tangential nozzle adjustable for height.

EFFECT: improved functional capabilities.
