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

                                        2014-11-20 0

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

                                        1、將瓶閥安裝在試驗夾具上,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;

                                        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(試驗壓力);

                                        3、打開截止閥;

                                        4、試驗開始時,電機(或氣缸)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,打開瓶閥,當壓力傳感器檢測到壓力升至試驗壓力時,瓶閥關閉,然后以8-15次/min的速度開啟和關閉瓶閥,直至完成試驗次數;

                                        5、試驗過程中扭矩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,打開截止閥,卸掉管路中的高壓氣體,然后再拆卸瓶閥。
