可燃气体报警器可以检测空气中可燃气体的浓度,一旦发现空气中的可燃气体浓度超过正常范围值,就会做出一级声光报警和二级排风或截止阀动作反应,给用户明确的示警,提醒用户进行可燃气体泄漏问题排查,避免因可燃气体泄漏而引发的爆炸、中毒问题,对保护人们的生命财产安全具有极为重要的意义。可燃气体报警器的定期检定工作可以为空气中可燃气体的浓度的实时监测提供基本保障。本文对可燃气体报警器计量检定中的相关注意事项进行说明,可为检定人员开展可燃气体报警器计量检定工作提供参考。 Combustible gas alarm can detect the concentration of combustible gas in the air. Once the concentration of combustible gas in the air is found to exceed the normal range, a sound and light alarm and a second stage exhaust or stop valve reaction will be made. Warning, to remind users to investigate the problem of combustible gas leakage, to avoid explosion caused by the leakage of combustible gas, poisoning, to protect people’s lives and property safety is extremely important. The regular verification of combustible gas alarm can provide basic protection for the real-time monitoring of the concentration of combustible gas in the air. In this paper, the relevant precautions in the measurement and verification of combustible gas alarm are described, which can provide reference for the verification personnel to carry out the measurement and verification of combustible gas alarm.
