| !!!使用中易出現的問題 |  |
| 1、由于關閉過載及溫差影響而使閥門打不開. 2、由于介質所帶固體顆粒沉積體腔底部.導致閘板關閉不到位. 3、密封泄漏多由于密封面擦傷所致。 | |
| Easy happening problem during the use | |
| 1 .The valve cannot be opened be-cause of overload close and temperature difference. 2. The media with solid particle deposit at the bottom of coelom leads to uncom-pleted close of flashboard. 3. More sealing leakage arising fromscratch of sealing surface. |
