                                        氣瓶閥耐氧氣壓力激燃試驗方法

                                        2018-11-01 0

                                        氣瓶閥進行耐氧氣壓力激燃試驗是為了檢驗閥在氧氣壓力激燃下是否安全。介質為氧氣或強氧化性氣體的閥,應進行氧氣壓力激燃試驗,試驗后閥無點燃、無灼焦痕跡。氣瓶閥進行耐氧氣壓力激燃試驗按以下3個步驟實施:

                                        1、試驗前應檢查氧氣激燃試驗裝置的升壓情況,在裝置中各部件的相互作用情況以及試驗儀表情況,符合試驗裝置的壓力循環特性如圖1和圖2所示后,將閥裝到試驗裝置上。

                                        2、試驗介質為純度大于等于99.5%的氧氣,其碳氫化合物符合GB/T3863,試驗壓力為閥的公稱工作壓力,氧氣加溫到60℃±3℃。

                                        3、60℃±3℃的氧氣通過啟動快速開啟閥(20ms),經過內徑為5mm,長1000mm的銅管直接進入被試驗的閥。這個試驗閥要承受從大氣壓力到閥的公稱壓力的20次壓力循環(閥關閉和打開各20次,開啟時進氣口要封住)。試驗結束后,把試樣閥拆開并仔細檢查,包括內部各零件,無點燃、無灼焦的痕跡。
