基于煤矿井下管道瓦斯流量仪的现状,分析了常用瓦斯流量仪使用过程中存在的不足,进行了结构创新设计,提出一种工作可靠、效率较高的便携式翼栅单孔瓦斯流量仪。该流量仪是根据翼栅原理直接测量气体流量,采用便携式结构,可直接显示测定结果,可进行多点测量,使用方便,体积小、重量轻,传感器采用插入结构可防止生锈及以外损坏,有利于保护仪器安全,仪器测量精度高。
Based on the status quo of coal mine gas pipeline flow meter, this paper analyzes the shortcomings of the commonly used gas flow meter in the process of using, and carries out the structural innovation design, and proposes a portable airfoil single-hole gas flow meter with high reliability and efficiency. The flowmeter is based on the principle of direct measurement of gas flow gate, using a portable structure, the results can be displayed directly, multi-point measurement, easy to use, small size, light weight, the sensor insert structure to prevent rust and other damage, Conducive to the protection of instrument safety, high precision instrumentation.
