汽閥(止回閥)是空气錘重要部件之一,它控制着錘头上抬同下压的动作。过去,我們車間的400公斤空气錘汽閥經常發生事故,三兩天或者一个礼拜就得换一次;甚至一兩个鐘头就坏了,这样就严重地影响着車間的生产。我們分析事故發生的原因,可能有兩方面(請看附圖): (1)当錘头上抬时,压縮空气通过汽閥10,使彈簧11被压縮,汽閥10退回去。有时压力过大,就把汽閥
Steam valve (check valve) is one of the important parts of the air hammer, which controls the hammer head up with the next pressure action. In the past, the 400kg air hammer valve in our plant was frequently hit by an accident and had to be changed in three or two days or once a week; even an hour or two went bad, seriously affecting the production of the workshop. We analyze the causes of the accident, there may be two aspects (see photo): (1) When the hammer lifts, the compressed air through the steam valve 10, the spring 11 is compressed, the steam valve 10 to go back. Sometimes the pressure is too great, put the steam valve
