Abstract

The gas sampling device comprises a sampling bag, a gas inlet pipe and a gas outlet pipe are fixedly arranged on the sampling bag, a first switch valve is fixedly arranged on the gas outlet pipe, one end of the gas inlet pipe of the sampling bag is fixedly connected with an extraction device, and the extraction device comprises a mounting plate; an air extracting pump and a storage battery are fixedly mounted on the mounting plate, the storage battery is electrically connected with the air extracting pump, the air outlet end of the air extracting pump is fixedly communicated with the air inlet pipe, a three-way connector is fixedly mounted at the air suction end of the air extracting pump, a sampling pipe is fixedly mounted at one end of the three-way connector, and a second switch valve is fixedly mounted on the sampling pipe; the other end of the three-way connector is provided with a connecting device, and the connecting device is sleeved with a detachable gas storage bag. The gas sampling device for the gas analyzer can solve the problem that sample gas collected by an existing sampling bag is a mixture of air and the sample gas in the bag.

Description

Technical field [0001] The present invention relates to the field of gas detection technology, specifically to a gas sampling apparatus for a gas analyzer. Background [0002] Gas analyzer is a process analysis instrument for measuring gas composition, mainly using gas sensors to detect the types of gases present in the environment, gas sensors are sensors used to detect the composition and content of gases. [0003] At present, most of the gas sampling bags are used to collect the sample gas, and the gas in the gas sampling bag is analyzed and detected by the gas analyzer, and the existing gas sampling bag is used, and the sample gas collected by the gas sampling bag is a mixture of the air in the bag and the sample gas, so that the purity of the sample gas is affected by the air content, resulting in inaccurate test results. Contents of the Invention [0004] (1) Solved technical problems [0005] In response to the deficiencies of prior art, the present invention discloses a ...
