超短型球阀端盖结构的改进

Structure improvement for super-short ball valve

阐述了普通超短型球阀在使用中容易出现的问题,提出了结构改进方法,使超短型球阀在设计使用中更趋向合理化。

This paper describes the easily arisen problem of the common type super- short ball valve during the use, brings forward the method of structure improvement, so as to make the super- short ball valve more rationalization during the design and use.
