试验结果表明阻爆控制器能配合快速切断阀可有效阻止瓦斯爆炸传播。
The test results showed that the explosion resistant controller could rapidly assist the shut-off valve to effectively prevent the gas explosion spreading.
通过推导公式计算快速切断阀的允许切断时间，并总结燃气锅炉供气系统中快速切断阀的选择方法。
The allowable shut-off time of fast shut-off valve is calculated by inferred formula and selection way of fast shut-off valve in the gas supply system of gas burning boiler is summarised.
