可燃气体报警器一级报警设定值为多少?
现如今,随着各类气体泄漏事件的发生,对于一些会涉及可燃气体和有毒气体泄漏的场所,如果未按国家标准设置检测报警装置会被判定为重大生产安全事故隐患。因此
为了确保安全,很多的场所都需要安装可燃气体报警器,并设定其报警值。那么您知道可燃气体报警器一级报警设定值为多少吗?下面逸云天小编为您介绍:

对于可燃气体检测一级报警值的相关规定,在国标《GBT 50493-2019》中有明确的要求:
1、可燃气体的一级报警设定值应小于或等于25%LEL;
2、线型可燃气体测量一级报警设定值1LEL·m。
因此,可燃气体报警器一级报警设定值应小于或等于25%LEL,也就是说可燃气体报警仪的一级报警值不能超过其最低爆炸极限浓度值的25%的体积分数。
另外,可燃气体的测量范围应为0~100%LEL,线型可燃气体测量范围为0~5LEL·m。可燃气体报警器必须能够至少可以检测到可燃气体爆炸下限内的气体浓度值,也就是说测量范围可以大于等于上述范围值,但不能小于该范围。
可燃气体报警器,一般包括固定式可燃气体报警仪和便携式可燃气体报警仪两大类,后者又可分为扩散型便携式可燃气体报警仪和泵吸型便携式可燃气体报警仪两种。在选用时,应根据现场的工况环境及自身需求来进行选择。不管是哪种类型的可燃气体检测器,在检测到可燃气体浓度值达到或超过一级报警值时都应当能够30~60s发出声光报警。作业人员撤离后应进行强制通风至少半小时后再由专业人员检查发生可燃气体泄漏的具体位置和原因。
综上所述,就是可燃气体报警器的一级报警设定值。按照目前国家规定,可燃气体报警器的低报一般设置在25%LEL,高报设置在50%LEL。如果大家对可燃气体报警器的报警值设置还有问题的话,欢迎来电咨询逸云天,我们将竭诚为您服务!
