2012-07-27 18:01:56 瓦斯q值測定儀具有結構緊湊，輕便安全，操作簡單，使用方便，性能穩定，測試迅速準確，讀數直觀可靠等優點，適合煤礦現場操作使用，在突出礦井有推廣應用價值。型瓦斯q值測定儀主要用于煤礦采掘工作面直接測定煤煤層鉆孔瓦斯涌出初速度，預測煤工作面的瓦斯突出風險性。ZWS-I型瓦斯q值測定儀，為煤層采掘工作面突出風險性預測工作提供了一種便攜快速測試儀器。可供煤礦防災部門，煤炭科研單位等使用，也可用于煤層抽放鉆孔瓦斯涌出量等參數的測定工作。能在有甲烷土崩瓦解氣體的風險場所使用。瓦斯q值測定儀由煤塵過濾器、外殼、面板和肩帶組成。在面板上裝有流量顯示器、進管咀和換擋流量計，借助于軟管和快速密封接頭將它們連接。瓦斯由進氣管咀經過軟管進入到流量顯示器和換檔流量計中，由于換檔流量計的節流作用，密封室內瓦斯壓力升高，推動流量顯示器指針擺動，從而測定煤層鉆孔瓦斯涌出初速度。People who visit the URL also visit below websites:
