SAMPLER FOR DRAWING SAMPLES OF LIQUID AND GAS AT INCREASED TEMPERATURES AND PRESSURES Russian patent published in 2003 - IPC

FIELD: study of physico-chemical properties of multi-component solutions containing one or several gaseous components in liquid-gas equilibrium state or in vertically stratified state. SUBSTANCE: proposed device includes autoclave, valve with stem coaxially running through obturator and sampler. Stem is revolving. Sampler is made in form of inserts calibrated in volume and turned over with bottom upwards. Said inserts are provided with screw covers and perforated neck and are mounted in perforated holder which is coaxially secured on obturator by means of bayonet lock. Several inserts with partially screwed covers are engageable with each other, with revolving stem of valve and with bottom of perforated holder by means of splined joints, thus making it possible to screw down all covers simultaneously during rotation of valve stem; covers are sealed up by means of knife seal over gasket ring made from inert metal. Proposed device makes it possible to draw sample duplicates without disturbance of thermodynamic and chemical equilibrium and to determined pH and chemical composition. EFFECT: enhanced efficiency. 7 dwg
