                                        氣瓶閥耐用試驗機的試驗方法闡述

                                        2014-07-04 0

                                        氣瓶閥耐用試驗機的試驗方法:

                                        1,將瓶閥安裝在夾具上,根據不同旋轉手柄和直線行程的閥門選擇不同的安裝夾具安裝好,并調整閥門相對于驅動機構的位置。

                                        2、打開手動閥,使高壓氣體進入高壓容器儲存起來,調節減壓閥,使輸出氣體壓力為瓶閥公稱工作壓力。

                                        3、關閉不試驗的工位的高壓截止閥,打開需要試驗的截止閥。

                                        4、試驗開始時,點擊將瓶閥關閉,氣控閥打開,壓力傳感器檢測到壓力上升至試驗壓力時,自動打開被測瓶閥,高壓氣體通過消聲器排出,排出后自動關閉被測瓶閥,如此往復,直至完成試驗次數,在試驗一定次數后,在被測瓶閥關閉狀態下暫停,檢測閥門的密封性能,如果無泄露,點擊開始繼續試驗,反之,試驗結束。

                                        5、試驗過程中傳感器會自動檢測電機輸出的扭矩,若大于設定扭矩,則會發出報警。

                                        6、當瓶閥損壞,不能打開時,試樣后端沒有壓力變化時,設備會自動停機,關閉氣控閥,打開被測閥前端的截止閥泄壓,卸掉管路中的高壓氣體,然后在拆卸瓶閥,試驗結束。
