气体测量装置
摘要：
本发明提供了气体测量装置，属于气体分析与测量技术领域，气体测量装置包括采样管路和设置在采样管路上的抽排装置，所述采样管路上设有用于测量待测气体的气体分析仪，所述采样管路包括采样主路和连接在采样主路上的采样支路，采样支路远离采样主路一端与大气连通，所述抽排装置设置在采样主路上，所述气体分析仪设置在采样支路上，采样支路上设有用于向气体分析仪提供正压检测气体的增压装置，在采样支路上设置增压装置将气体分析仪进气口处的待测气体变成微正压，解决了现有技术中气体分析仪置于高负压状态易损坏的问题。
摘要（英）：

The invention provides gas measurement devices and belongs to the technical field of gas analysis and measurement. A gas measurement device comprises a sampling pipeline and a pump drainage device arranged on the sampling pipeline. A gas analyzer for measuring to-be-measured gas is arranged on the sampling pipeline. The sampling pipeline comprises a sampling main way and a sampling branch connected with the sampling main way. The end, away from the sampling main way, of the sampling branch communicates with the atmosphere. The pump drainage device is arranged on the sampling main way. The gasanalyzer is arranged on the sampling branch. A supercharging device for supplying positive pressure detection gas to the gas analyzer is arranged on the sampling branch. Through arranged of the supercharging device on the sampling branch, the to-be-measured gas at a gas inlet of the gas analyzer is changed into micro positive pressure, so the problem that in the prior art, the gas analyzer is liable to damage in a high negative pressure state is solved.
