The invention relates to heat and power generation, in particular to sampling devices, and can be used at heat and nuclear power plants for sampling moisture from humid steam in the turbine flow section, 1 of all, the most corrosive primary condensate.

The aim of the invention is to increase the representativeness of the sample by increasing the accuracy of measuring corrosion of siHHo corrosive gases in a sample of 1: liquid.

The drawing shows a diagram of a device for sampling a liquid from a vapor.

: The device contains sampling element 1, separator 2, glass 3 for | boron of the separated liquid phase, stopped inside the separator 2

connected by pipeline 4 with the intake element 1. The steam npio space of the separator 2 is connected by a pipe

Confirmation 5 with a steam discharge element- 6, and pipeline 7 - with a flow-through storage capacity 8. The stack- 3 is made with an overflow opening 9, which provides overflow of Liquid from cup 3 to the separator 2 g | and also limits the speed to 1 | Irrigation through the flow container 8. The end of the pipeline 4, introduced into the cup 3, is located above the overflow port 9, and the lower end of the Cana 3 station is connected by pipeline 10 with a cumulative tank 8. For the continuous removal of condensate from the separator 2, the latter is equipped with a hydraulic separator 11.

The device works as follows.

The sample of wet steam with the help of the wind intake element 1 enters the rio pipeline 4 into the separator 2, in

the bottom end of the glass 3, filled with an overflow hole 9 in the upper part. The device is equipped with a water seal 11. 1 Cp. f-ly, 1 ill.

glass 3 which is the separation of moisture from steam due to the difference in their densities.

The liquid phase from the glass 3 with open fittings (not detected) enters the flow-through storage tank 8, fills it and drains into the steam volume of the separator 2 through line 7. Hole 9 in the glass 3 prevents flooding of the end of pipeline 4 when the moisture content in the steam is higher . The dry steam from the separator 2 is withdrawn to the same; the same step through the pipeline 5 and the steam removal element 6, and the removal of liquid from the vapor space of the separator 2 is carried out through the hydraulic lock 11.

After completion of the sampling process, tank 8 is disconnected, disconnected, and sent to the laboratory for analysis of the content of dissolved oxygen in the sample.

The proposed device will make it possible to increase the representativeness of the sample by increasing the accuracy of obtaining quantitative data on its chemical composition from the flow section of the turbine, since the liquid is repeatedly exchanged in the storage tank in order to eliminate the effect of even residual amounts of oxygen sorbed by the vessel walls.
