SAMPLER Russian patent published in 2002 - IPC

FIELD: oil industry. SUBSTANCE: invention relates to devices for taking samples of moil products and oil from reservoirs for testing density, temperature and other parameters of products. Proposed sampler has system of intake and drain pipes, column with its fasteners inside reservoir and control and drain devices found beyond the limits of reservoir. Column is made in form of perforated tube with brackets installed across the tube parallel to each other at definite step intake pipes are mounted on brackets. Inner flexible pipes are hermetically connected to intake pipes. Other end of flexible pipes is connected to through pipe coupling. The latter is installed in hole of cover of reservoir side inspection hatch from inner side. Outer flexible pipes are connected to each through pipe coupling from other side. Ends of outer pipes are connected to t-pipes arranged in definite order. On panel installed at preset distance from reservoir. T-pieces are installed so that common axle of two holes of each t-pipe is arranged in horizontal plane and is connected to panel with outer flexible pipes at one side and with sampling cock at other side. Axle of third hole of each t-pipe is arranged vertically, with hole pointed downwards. Drain pipes with drain cocks are connected to each t-pipe from below. Lower ends of all drain pipes are united into manifold made in form of drain pipe stopped at one side and arranged at angle relative to horizontal and provided with stop cock at other side. Dummy hole with mounting level lower than reservoir level is installed before cock behind manifold part. EFFECT: improved operating conditions, provision of ecological safety at sampling and possibility of checking of temperature in zone of sampling. 12 cl, 5 dwg
