气体泄漏率检测装置
摘要：
本公开提供一种气体泄漏率检测装置，该气体泄漏率检测装置包括壳体、弹性膜、测距组件和处理组件。壳体具有贯通的第一端和第二端；弹性膜密封连接于壳体的内壁，并能在气体的冲击下弹性变形；测距组件设于第一端且正对于弹性膜，用于检测弹性膜与测距组件之间的距离；处理组件设于壳体外，用于根据距离确定弹性膜的变形量，并据以确定气体的泄漏率。
摘要（英）：

Provided is a gas leakage rate detection apparatus comprising a shell body, an elastic membrane, a range finding assembly and a processing assembly. The shell body comprises a first end and a second end communicated with each other, the elastic membrane is connected onto an inner wall of the shell body in an airtight manner, elastic deformation can be caused due to gas impact, the range finding assembly is arranged on the first end and right opposite to the elastic membrane and is used for detecting distance between the elastic membrane and the range finding assembly, the processing assembly is arranged outside the shell body and is used for determining a deformation quantity of the elastic membrane, and therefore gas leakage rates can be determined based on the deformation quantity.
