PRESSURE STABILIZER Russian patent published in 2000 - IPC

FIELD: high-pressure different-designation pipelines of mean and large diameters, namely elimination of hydraulic shocks, pressure pulsations and failures. SUBSTANCE: pressure stabilizer includes portion of central apertural pipeline with joined flanges 2. Said pipeline portion is arranged in cylindrical prechamber 3. Damping chambers 4 are placed outside prechamber and they have limiters of elastic member motion. Limiter is in the form of apertural partition behind which movable elastic members are arranged. Said members are made of elastically damping material and they are embraced by sealed envelope of elastic material. In each damping chamber there is additional flexible member that may move in direction of disturbance action and separates hydraulic part of elastic chamber from cavity filled with pressurized gas. Such structure of damping chamber allows to increase mass yielding of apparatus while keeping minimum change of mass-dimensional characteristics of stabilizer and simultaneously reducing supercharging pressure in gas cavity by 30-50% and to provide high efficiency of pressure stabilizing in pipelines with diameters more than 0.1 m and working pressure range (7-16) MPa. EFFECT: improved design, enhanced characteristics of pressure stabilizer. 2 dwg
