摘要
设计了一种不仅可以进行常规气密性检测,还可以进行系统的慢性泄漏检测的旋转式气密性检测装置,介绍了该装置的结构、原理、标定方法与应用实例。该装置将差压测量系统的比较腔融入测量装置中,让U型管具有压差测量和连通管道的双重功能,在保持较高检测精度的同时,简化了测量系统,缩小了体积,减少了阀门等运动部件,提高了检测装置的可靠性。
This paper presents a rotatable apparatus . The ordinary gas leakage and slow leakage can be quickly detected with this apparatus. This paper introduces the principle of this apparatus and its application. The rotatable apparatus for gas leakage detecting, in which a U tube is employed as the manometer as well as the connecting pipe between the standard chamber and the system to be detected, which provides the apparatus with high precision, compacted volume and less valves.
