APPARATUS FOR FEEDING LIQUID DISCHARGED FROM ACCUMULATION RESERVOIRS Russian patent published in 2005 - IPC

FIELD: installations for pumping liquefied products of gaseous mixtures including cryogenic ones, possibly in gas production, chemical, cryogenic and other industry branches where products produced by separation of gas mixtures under pressure are used.

SUBSTANCE: apparatus for continuous displacement supply of liquid out of accumulation reservoirs includes two accumulation reservoirs, balance beam engaged with unit for positively switching pressure of displacing gas from reservoirs; pipeline system with fitting for automatic switching at charging reservoirs and discharging working liquid from them to user. Flow rate controller is mounted at outlet of pipeline for discharging liquid to user. Reservoirs, pipelines, fittings are mounted in housing of installation; said housing may change its position on articulation joint support by action of gravity center motion caused by emptying one reservoir and filling other reservoir. Unit for positively switching are in the form of spring-articulation joint drives secured at one side to foundation support and at other side to rods of positive action valves.

EFFECT: simplified design, enhanced operational reliability of installation in mode for self-controlling its efficiency and pressure of discharged product.
