摘要/Abstract

摘要： 按照ISO 16852进行了20组爆轰试验，10组无加速环，10组有加速环。结果表明，有加速环作为火焰加速装置时，更易形成稳态爆轰，平均火焰速度和平均压力较为稳定，且在一定范围内重复性较高。管道阻火器进行稳态爆轰测试时，推荐使用加速环作为火焰加速装置。

关键词: 消防；阻火器；加速环；稳态爆轰

Abstract: In this paper, 20 groups of stable detonation flame arrest tests were carried out in accordance with the international standard ISO 16852:2016, 10 groups had no accelerated rings and 10 groups had accelerated rings. The results show that it is easier to form stable detonation when the accelerated ring is used as the flame accelerator, and the average flame velocity and pressure are relatively stable, and the repeatability is higher in a certain range. In stable detonation tests of in-line flame arresters, it is recommended to use the accelerated ring as the flame accelerator.

Key words: fire protection; flame arrester; accelerated ring; stable detonation
