摘　　要：造纸厂蒸煮锅锅盖阀采用普通球阀,如果阀座的2个密封面不能同时良好接触,就会导致泄漏大、寿命短等缺陷。为此研制出一种新型的单阀座球阀,当阀口切断时,由于阀出口侧介质压力直接作用在球面上,使得密封效果随着出口压力的增加而提高。本文重点介绍了锅盖阀单阀座结构创新性设计及内流道CFD数值模拟,结果表明,这种新型结构的锅盖阀在实际应用中有非常好的的效果。If the paper mill uses common ball valve on digester capping valve, two seat seal face can＇t get good contact and will cause leakage and short life, so a new kind of single seat ball valve was designed. When the valve cut off, the out- side pressure works on sphere, which makes the sealing effect improve with outside pressure increase. This paper intro duced a new kind of single seat ball valve＇s design and calculation, and the CFD simulation. The results showed that the new structure of the capping valve is very effective in real application.
