Problems solved by technology

[0003] Nowadays, many chemical plants still adopt the traditional open sampling method. The typical method is: through a valve as a sampling port, use a wide-mouth bottle to directly intercept the material in the pipeline or tank; as a traditional sampling mode, in this sampling and analysis During the process, the toxic and harmful steam will be volatilized again, which will have serious consequences on the health of the sampling personnel and analysts, and pollute the environment; moreover, the traditional sampling device will pollute the sample during the sampling process, causing the analysis results to be polluted. Not representative of the sample

Abstract

The invention provides a closed sampling device which comprises: a sampling needle comprising a liquid feeding needle, a gas discharging needle, a liquid inlet communicated with the liquid feeding needle, and a gas outlet communicated with the gas discharging needle; a protective cover component comprising a protective cover, and a support ring connected with the protective cover; and a sampling bottle component comprising a sampling bottle, a bottle cap, and an elastic gasket located between the sampling bottle and the bottle cap. The closed sampling device of the invention is equipped with the sampling needle; sampling is carried out by puncturing the elastic gasket sealed at the opening of the sampling bottle by the liquid feeding needle and the gas discharging needle on the sampling needle; the sampling and gas discharging processes are completed in closed environment; during sampling, the requirements of zero leakage and zero discharge are reached; and the sampling device of the invention is convenient, rapid and safe in sampling, and causes no environment pollution.

Description

technical field [0001] The invention relates to a sampling device, in particular to an airtight sampling device. Background technique [0002] In chemical, pharmaceutical and other production processes, it is necessary to take samples from pipelines or tanks for analysis, so as to monitor the state of the process medium in the production process. In order to create a clean factory, reduce environmental pollution, and protect the health and safety of on-site sampling and laboratory personnel, airtight sampling is advocated for toxic and harmful materials. Closed sampling means that during the sampling process, the sampling medium does not have any contact with people or the environment, and the sampling is completed in a closed system. Airtight sampling can ensure the cleanliness of chemical units, no peculiar smell on site and guarantee the health of personnel in petrochemical units. [0003] Nowadays, many chemical plants still adopt the traditional open sampling method. ...
