一种恒压法气密性检测装置的设计与应用
Design and application of an airtightness test device for the constant pressure method
摘要
Abstract
Objective To design an airtightness device based on the constant pressure method and use it for the airtightness detection of the rooms in the type b2 laboratory within ABSL-3.Methods Based on the require-ments of airtightness detection using the constant pressure method and the structural characteristics of type b2 laboratory within ABSL-3 rooms,a device composed of a support frame,a negative pressure air pump,a flow regulating valve,a glass rotameter and a fixing support frame,etc.,was designed.Three type b2 laboratory within ABSL-3 rooms and their buffer rooms that had passed airtightness detection by a third party were se-lected as the detection objects.This device was used to maintain the relative negative pressure value of the rooms below-250 Pa for airtightness detection.Result The detection results of the device were basically con-sistent with the third-party detection results and met the standard requirements.Conclusion By using this de-vice,the rapid and accurate detection of the airtightness of type b2 laboratory within ABSL-3 rooms can be achieved.It effectively meets the necessary airtightness detection requirements and has good value for promo-tion and application.关键词
