一种法兰结构中O型密封圈漏率检测装置

An Equipment for Leakage Rate Testing of O-ring in the Flange

设计搭建O型橡胶密封圈漏率检测装置,该装置能够灵活控制待考核密封圈压差和工作温度,模拟爆炸容器中密封圈工作状态。装置由密封法兰、测量系统、加温加压系统及检漏系统组成,使用氦质谱检漏仪测量漏率。实验结果表明装置设计合理,符合实验要求。

An equipment for leakage rate testing of O-ring was designed. The equipment could control the pressure and temperature of O-ring under testing, and simulate the environment in the explosion vessel. The equipment was composed of flange, measurement system, heating and adding pressure system, leak hunting system, it measured the leakage rate by a helium leak detector. The equipment was used in test experiments, and the result accorded with the requirement.
