!!!使用中易出现的问题 | |
1、由于关闭过载及温差影响而使阀门打不开. 2、由于介质所带固体颗粒沉积体腔底部.导致闸板关闭不到位. 3、密封泄漏多由于密封面擦伤所致。 | |
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. |
