Description

Technical Field

[0001] This utility model relates to the field of chemical gas sampling, and in particular to a chemical gas safety detection and sampling device. Background Technology

[0002] Various gaseous substances are produced during chemical industrial production, reactions, or processing. The demand for these gases is often distributed across different regions or industries. To meet these demands, the gases need to be transported from the production site to the consumption site.

[0003] During the transportation of existing chemical gases, it is necessary to periodically sample and test the gaseous materials to monitor their composition and content in real time. Before testing, a sampling device is required to collect and sample the chemical gases. The extraction pipe and connecting pipe of the sampling device are connected by a flange ring, but there are gaps at the connection, resulting in poor sealing. Gas can easily escape through the gaps. When leaking, it may mix with air to form an explosive gas mixture, which can easily cause accidents and pose a great threat to the personal safety of sampling personnel. Utility Model Content

[0004] The main objective of this invention is to provide a chemical gas safety detection and sampling device that can effectively solve the technical problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The first and second sealing sleeves are aligned with each other. A sealing groove is formed on one side of the first sealing sleeve, and a sealing ring is formed on one side of the second sealing sleeve, with one end of the sealing ring extending into the sealing groove. A sealing gasket is formed on one side of the first sealing sleeve, with one side of the sealing gasket fitting against one side of the second sealing sleeve. An extension tube is fixedly connected to one end of the connecting tube, with one end of the extension tube extending into the extraction tube.
