摘要
提出了利用流量喷嘴和标准试验风管装置来测定防火阀空气动力性能(漏风量和阻力)的试验方法。该方法简便易行,可获得较为准确的结果。该法也适用于防火调节阀和排烟阀的性能试验。
A testing method for determining aerodynamic performances of fire damper by the use of the testing apparatus of air flow measuring nozzle and standard test duct, is presented here. These performances include air leakege and air resistance. The method is convenient and easy to use, and precise results can be obtained. The method is also suitable for fire -regulating damper and smoke -discharging damper.
