                  实验室气路安装方法设计注意事项


                  实验室气路安装系统主要由气源切换系统(一级减压系统)、管道及连接件系统、二级调压系统、气体过滤纯化系统、气体报警系统、压力表、球阀等组成。那么实验室气路安装对安?#23433;牧系?#35201;求有哪些呢?


                  1、高压波纹软管 

                  外表不锈钢金属网内衬PTFE材质,长度1米以上,通径大于6MM。一端符合标准钢瓶的连接型号,另一端连接自动切换系统。承受大于3000PSI。其特性为?#33322;?#20928;光亮、柔软、防腐。 


                  2、低压报警器 

                  低压报警器多触点可模拟数据输出型,报警器可蜂鸣闪光同时显示报警气体的名称。防爆接线、信号模拟和自动切换系统汇流排相匹配。


                  3、减压阀 

                  316L不锈钢材质。一级减压阀进气压力0-200bar,出气压力0-16bar;二级减压阀进气压力0-16bar,出气压力0-6bar。进出口接口1/4” FNPT螺纹,压力表接口1/4” MNPT螺纹。


                  4、管道 

                  管道采用内表面BA级316L ASTM A269标准不锈钢管道,316L不锈钢光亮退火,母材符合BA级高纯管道,管道的内表面处理值要小于0.37U。管道的标准:1/4”---1/2”壁厚0.88mm。zui大承受压力为300 bar,气管适用纯度等级为5.0的气体。


                  5、接头 

                  采用316L不锈钢光亮退火,母材符合BA级的高纯气路配件。双卡套设计。硬化处理之后卡套,具备对管子的耐震力及高抓力,使管子在任何情形下不易松?#35759;?#36896;成危险。后卡套内部有凹槽,安装时可以降低扭力,安装者可以轻易将接头锁至标准圈数。螺帽内部螺纹做镀银处理,具备安装时必要的润滑,延长螺纹寿命。
