摘　　要：目的实验室通风系统控制是合格实验室管理的关键问题。探讨通风系统中阀体的选用方法,为实验室环境质量保障提供参考。方法利用文丘里阀压力无关与蝶阀压力有关的特性,比较了几个实施方案的优劣。结果与结论直流式全新风中央空调系统是可推荐的实验室通风系统,应根据投资情况、使用功能、节能要求来选择阀体。Objective The control of laboratory ventilation system is the key problem in qualified laboratory management. The aim of this study was to explore the method for selection of valve body for ventilation system and to provide reference for guaranteeing the environmental quality of laboratory. Methods Based on the characteristics of pressure-independent Venturi valve and pressure-dependent butterfly valve, the merits of their respective operating schemes were compared. Results and Conclusion Direct-current fresh air central air conditioning system is a promotable laboratory ventilation system. The valve body should be selected according to the investment, the function and the energy-saving requirement.
