Gas sampling and detecting device

气体采样检测装置

Abstract

气体采样检测装置。传统的检测装置在检测密闭的过渡舱外气体时,都要把密闭的过渡舱外的气体放在容器内在过度舱内检测,容易操作失误导致气体外泄污染密闭的过渡舱空气。一种气体采样检测装置,其组成包括:密闭的过渡舱(9),所述的密闭的过渡舱安装有手动排气阀(1),所述的手动排气阀通过气体检测管A(3)与气密性气体检测室(6)连接,所述的气密性气体检测室设置有一组检测仪表(8),所述的气密性气体检测室通过气体检测管B(4)与个体粉尘采样器(7)连接,所述的个体粉尘采样器通过气体检测管C(5)与单向排气阀(2)连接。本实用新型用于煤矿气体采样检测。
The utility model provides a gas sampling and detecting device. When gases outside airtight transition cabins are detected by traditional detecting devices, the gases need to be put in containers and detected in the transition cabins, so that misoperation is easily caused, thus resulting in gas leakage and pollution of the air in the airtight transition cabins. The gas sampling and detecting device comprises an airtight transition cabin (9), wherein a manual exhaust valve (1) is installed in the airtight transition cabin and is connected with a chamber (6) for detecting gases with tightness via a gas detecting tube A (3); the chamber for detecting gases with tightness is provided with a group of detecting instruments (8); the chamber for detecting gases with tightness is connected with an individual dust sampler (7) via a gas detecting tube B (4); the individual dust sampler is connected with a one-way exhaust valve (2) via a gas detecting tube C (5). The gas sampling and detecting device is used for sampling and detecting gases in coal mines.
