SAMPLE-TAKING DEVICE Russian patent published in 2007 - IPC E21B49/08 G01N1/10 

FIELD: oil and gas industry, possible use for taking samples of liquid from pipelines.

SUBSTANCE: device contains main pipeline, sample-taking section, fastened to main pipeline with possible extraction of sample with enveloping of transverse cross-section of liquid flow without losses, draining valve and manometer. Sample-taking section at input of liquid flow inside the main pipeline is provided with branch pipe with radial apertures, positioned in front of liquid flow with inclined upper end. Cut of inclined end is positioned on the side of branch pipe opposite to radial apertures. Device, narrowing the flow, is mounted behind branch pipe in main pipeline. Draining valve is made in form of core slide valve, spring-loaded relatively to sample-taking section, body with draining aperture and coil. Core slide valve is hermetically mounted inside the body and made of dielectric material. Coil is positioned on external surface of body. In original position core slide valve hermetically covers draining port of body. In working position core slide valve under effect of electromagnetic field, created by coil, is capable of axial movement inside the body.

EFFECT: simplified construction, increased durability.
