SU73316A1 - Sampler designed, for example, to power a viscometer - Google Patents

Description

Viscometers are powered by o6i.i to determine the viscosity of liquids from samplers connected to a vessel containing the test liquid by a piping system.

A distinctive feature of the proposed sampler is that the test liquid from the vessel is fed into it using an ejector device inside the vessel at the lower end of the feeding tube, into which a tube is inserted, connected to a compressed gas balloon, for example, hydrogen, neutral with respect to the studied liquid. .

The drawing shows a vessel} containing the test liquid, sampling device 2, refrigerator 3, viscometer 4 and a pipe system connecting the above elements.

The gas, which has exhausted from the tube 5 into the feed tube 6, carries along with it the liquid — into the sampler 2, from where the fluid from the tube 7, enclosed in the refrigerator 3, comes in cooled form into the viscometer 4. Excess fluid through the tube S flows back into the vessel 1 .

The liquid, having passed the viscometer 4, flows in a stream through the tube 9 into the viewing glass JO and then through the tube // into the vessel / ..

The tube 12 connecting the sight glass JO to the upper part of the sampler 2 equalizes the pressure of hydrogen, and thus the flow of fluid through the entire system. From the sampler to the sight glass occurs by gravity under constant pressure. By tube 13, gas from sampler 2 enters vessel U.

Subject invention

A sampler, for example, designed to power a viscometer, made in the form of a vessel connected to a vessel, contains one. liquid under test, two pipes - a feed one, an inlet horse mounted immersed in a liquid, and a drain outlet of which is located above the liquid level in the first vessel, characterized in that an ejector is used with a liquid entraining gaseous liquid to carry out the lifting of the sample in the sampler medium neutral in relation to the liquid under study.
