关于生物安全实验室压力控制的探讨

生物安全实验室的安全性与通风空调系统的设计、施工、运行、管理密切相关，在空间上予以物理阻断，避免污染和交叉感染是保证人员和环境安全的主要措施。本文就生物安全实验室压力控制的不同方法进行比较，介绍了文丘里压力控制阀的基本原理、特点，及工程的实际应用效果。

Discussion on the Pressure Control of Biosafety Laboratories

The biosafety laboratories' safety has close relationship with the HVAC system design, construction, operation and supervision. Given the primary barrier to the operator and environment, the secondary barrier to biosafety and the surrounding, the main measure is to guarantee the safety of personal and environment. This paper will compare the different pressure control measure, introduce the principle and characteristic of Venturi pressure control and introduce practice effect.
