Embodiment 1

[0035] Connect and install the first connecting pipe 2, the first pipe fitting tee 5, the second connecting pipe 4, the air pump 3, the second pipe fitting tee, the third connecting pipe 11, the fourth connecting pipe 12, the second restrictor valve 10, the second Six connecting pipes 9, gas analyzer 8, fifth connecting pipe 7, first flow limiting valve 6, the connection relationship is as follows figure 1 As shown, the first connection pipe 2 and the fourth connection pipe 12 have an open-ended connection structure. Adjust the first flow-limiting valve 6 and the second flow-limiting valve 10, and start measuring after the adjustment is completed. Due to the open-end structure, it can measure the carbon dioxide content in a certain area.

Embodiment 2

[0037] Connect and install the breathing chamber 1, the first connecting pipe 2, the first pipe fitting tee 5, the second connecting pipe 4, the air pump 3, the second pipe fitting tee, the third connecting pipe 11, the fourth connecting pipe 12, the second flow limiting Valve 10, sixth connecting pipe 9, gas analyzer 8, fifth connecting pipe 7, first flow limiting valve 6, the connection relationship is as follows figure 1 As shown, a closed path is formed. Place the breathing chamber 1 outside a certain volume of soil, and form a closed surrounding structure for the soil, adjust the first flow limiting valve 6 and the second flow limiting valve 10, and start measuring after the adjustment is completed. Due to the closed structure of the connecting loop, it is possible to measure the carbon cycle within a unit soil volume.

Abstract

The invention belongs to the technical field of a pressure regulating structure design of a gas analyzer, and in particular to a gas analyzer pressure regulating structure, comprising a first connecting pipe, a second connecting pipe, an air pump, a third connecting pipe, and a fourth connecting pipe which are sequentially connected. A fifth connecting pipe, a gas analyzer, and a sixth connectingpipe are sequentially connected. The fifth connecting pipe is respectively connected to the first connecting pipe and the second connecting pipe through a first pipe tee. The sixth connection pipe isrespectively connected to the third connecting pipe and the fourth connecting pipe through a second tube tee. A first restrictor valve is mounted on the fifth connecting pipe for defining an air outlet pressure of the gas analyzer. By mounting the first restrictor valve on the fifth connecting pipe, the invention can effectively control the air pressure of the pipeline, thereby creating a stable pressure environment for the gas analyzer, and has the characteristics of accurate measurement results.

Description

technical field [0001] The invention belongs to the technical field of pressure regulating structure design of a gas analyzer, in particular, the invention relates to a pressure regulating structure of a gas analyzer. Background technique [0002] Carbon flux is one of the most basic concepts in carbon cycle research, expressing the total amount of carbon in an ecosystem passing through a certain ecological section. With the industrialization of human society in the past hundred years, human life has undergone tremendous changes. At the same time, the carbon dioxide produced by industry and life has continuously increased the concentration of carbon dioxide in the atmosphere. The intensification of the carbon cycle and the continuous infiltration of carbon dioxide into the soil will lead to the continuous increase of the carbon flux of the pedosphere as a carbon storage, so that it will gradually affect a certain area of ​​the land or the entire land, making a certain area o...
