2012-07-27 18:01:56 瓦斯q值测定仪具有结构紧凑，轻便安全，操作简单，使用方便，性能稳定，测试迅速准确，读数直观可靠等优点，适合煤矿现场操作使用，在突出矿井有推广应用价值。型瓦斯q值测定仪主要用于煤矿采掘工作面直接测定煤煤层钻孔瓦斯涌出初速度，预测煤工作面的瓦斯突出风险性。ZWS-I型瓦斯q值测定仪，为煤层采掘工作面突出风险性预测工作提供了一种便携快速测试仪器。可供煤矿防灾部门，煤炭科研单位等使用，也可用于煤层抽放钻孔瓦斯涌出量等参数的测定工作。能在有甲烷土崩瓦解气体的风险场所使用。瓦斯q值测定仪由煤尘过滤器、外壳、面板和肩带组成。在面板上装有流量显示器、进管咀和换挡流量计，借助于软管和快速密封接头将它们连接。瓦斯由进气管咀经过软管进入到流量显示器和换档流量计中，由于换档流量计的节流作用，密封室内瓦斯压力升高，推动流量显示器指针摆动，从而测定煤层钻孔瓦斯涌出初速度。People who visit the URL also visit below websites:
