SU80265A1 - Device for continuous sampling of fluid from pipelines - Google Patents

Description

The known devices for continuous sampling of fluid from pipelines, the operation of which is based on the use of the pressure difference before and after the diaphragm embedded in the pipeline, do not provide the possibility of sampling insignificant in percentage to the main flow of samples.

The proposed device does not have this disadvantage. It allows continuous sampling in small quantities from large streams and prevents mechanical impurities from entering the sample.

This is achieved by a device in the form of a differential valve, of which there is a half in the outlet of the liquid chamber of the chamber 1, directly: p1 connected to the pipe line; o / 1y. as well as the use of phi, ltra and cold1;

The water valves 22 are intended to shut off the tubes 7 and 21 and also the tubes 25 supplying water to the refrigerator 20.

The device operates as follows. Since the speed and pressure S of the diaphragm is different from the speed and pressure at the point of connection of the tube 5, the difference of these pressures is a function of the flow velocity only and does not depend on the static pressure in the pipeline / 5. This pressure difference is transmitted to norply 5, the latter accordingly opens the passage at the clan. B. Mercury 4, filled with Yun1, and the cavity of Veptln, eliminates the use of the packing device at the clan gun 6. The liquid, cleaned by means of the valve 18 and cooled in the refrigerator 20, enters the float chamber 2, where, thanks to the float 3, connected to the valve 4, maintains a constant level.

The use of fnltra 18 n ho; 1odiln1n and 20 causes the normal effect of ycTpoiicTBa, independent of the presence of mechanical impurities in the fluid and its temperature. In addition, the accumulation of Mexasin impurities in the iS filter makes it possible to determine their average concentrations. in the fluid passing through the pipeline.

The PDD of pure liquids is used without the filter / 8.
