高压气体钢瓶的存放与安全操作(1)气瓶必须存放在阴凉、干燥、远离热源的房间,并且要严禁明火,防曝晒。除不燃性气体外,一律不得进入实验楼内。使用中的气瓶要直立固定。(2)气瓶的颜色及阀门转向 为了保证安全,气瓶用颜色标志,不致使各种气瓶错装、混装。同时,为了不使配件混乱,各种气瓶据性质不同,阀门转向不同。 通则:气瓶为红色,左转。有毒气体(气瓶为黄色)、不燃气体右转。 ...
2.气瓶间内设立一次调压面板,其中二托一面板带吹扫铜镀铬面板4套。3.压力调节器入口前需加装烧结金属过滤器以防止颗粒等杂质污染系统。4.所有面板均配备吹扫阀,可实现对面板的清洗置换。5.压力调节器及相关管件均需牢固的固定在压力调节面板上,面板应设计的紧凑而合理,以尽量减少系统中的死体积。6.压力调节面板应采用全不锈钢材料制成,并且牢固的固定在可靠的位置上,确保其安全性。...
