Description

- -, I,:. A device for sampling a liquid fire fluid to samplers for sampling non-volatile liquids, such as wastewater, and can be used in all sectors of the chemical and petroleum industry. Ivveto liquid sampling device, containing its sample tube, collection sample, tube with capillary choke for supplying compressed air from the source of compressed air, flow glass fl. The drawback of the device is the impossibility of obtaining samples of a small volume for a long period of time. The aim of the invention is to ensure that sampling of liquid from any depth is possible and to ensure that samples of small volume 0a are obtained for a long time. This goal is achieved by the fact that the device is equipped with reservoirs installed one above the other on the surface of the earth, and flexible hoses located between the upper part of each auxiliary capacity and the lower part of another auxiliary capacity and between one auxiliary capacity and the sample collection and buffer capacity. It is advisable to perform one of the hoses located between the auxiliary tanks with a calibrated capillary. The drawing shows a general view of a liquid sampling device. The device contains a collection of 1 sample, buffer capacity auxiliary tanks 3 and 4, located one above the other. Auxiliary tank 4 is equipped with a funnel 5 with a filter for communicating the internal cavity with a vent (ZH1Ogatelnaya tank 4 with the atmosphere. Auxiliary tanks 3 and 4 are interconnected by flexible hoses 6 and 7 connecting the top of each auxiliary tank to the bottom of each other tank) Auxiliary tank 3 is connected by flexible spurs Tgamn 8 with sample container 1 and buffer tank J2. Flexible hose 7 is made with a calibrated capillary 9,

The liquid sampling device operates as follows.

Worker. FLUID and auxiliary tank 3 through the calibrated cap 9 nepeTeKaieT into the auxiliary tank 4 | You can use it through the BqioBKy 5 circuit. Through Ktepe, the flow of the working fluid in the auxiliary tank 3 into the flexible container 4, the collection of 1 sample and the buffer capacity of the LG fill the hole. After the vapor collection sample 1, it is introduced into, collected, then lowered again.

To bring the device into the working Zolozhiv, the auxiliary tank 4 has a height ti that is greater than or equal to the height from the bottom of the buffer tank 2 at the level of the surface of the wastewater. As a result, the working fluid through the Mgbq hose 6 flows into the auxiliary tank 3. The airbag that enters the device displaces the sample from the buffer (| first tank 2 and in the test tank 1. After that, the auxiliary tank 4 is returned to its original

position, causing the device again ready to work.
