【摘要】：剖析《建筑通风和排烟系统用防火阀门》中关于环境温度下的漏风量和耐火性能的试验设备和试验步骤的规定,总结防火阀门漏风量测量试验过程中的问题,包括漏风量试验安装繁琐;标准孔板流量计选用具有局限性;系统漏风量小于25 m3/h难于实现;引风机选型复杂和漏风量计算过程中温度压力修正模糊等。建议标准修订时,可采用转接头进行防火阀门安装试验;增加标准孔板流量计关键参数和适用范围的描述;重新定义系统漏风量,保证可操作性;具体规定引风机的风量;增加漏风量测量过程中气体介质冷却装置等。
[Abstract]:This paper analyzes the regulations on the test equipment and test steps for air leakage and fire resistance of building ventilation and smoke exhaust system under ambient temperature, and summarizes the problems in the air leakage measurement test process of fire proof valves. It includes the complicated installation of air leakage test, the limitation of selecting standard orifice plate Flowmeter, the difficulty of realizing air leakage less than 25 m3 / h, the complicated selection of draft fan and the modification of temperature and pressure in the calculation of air leakage, etc. When the standard is revised, it is suggested that, The key parameters and applicable range of the standard orifice Flowmeter can be increased by using the rotary joint to carry out the installation test of the fire-proof valve, the air leakage rate of the system can be redefined to ensure the operability, and the air volume of the induced fan can be specified in detail. Increase air leakage measurement in the process of gas medium cooling device and so on.
