波纹管球芯阀门的开发与应用

DEVELOPMENT AND APPLICATION OF BELLOWS GLOBE VALVE

介绍一类新型专利技术阀门——“波纹管球芯阀门”。这种新型阀门有下述基本类型：ＢＱＪ型波球截止阀，ＢＱＪ－Ｈ型波球截止－止回阀以及改进型波球阀门。波纹管球芯阀门采用了二项新技术设计构思，首先是采用浮动球面阀瓣，其次是采用波纹管替代填料密封。它具有性能优良、操作方便、使用寿命长的显著特点。

One new type patent technical valvebellows globe valve is intruduced.This neq type valve have following basic categories;BQJ type bellows globe valve;BQJH type bellows globecheck valve and improved type bellows globe valve.Bellows globe valves adopt two items of new technical desigh conception.At first,free floation globe valve disc is adopted and then the bellows is substituted for packing seal.They have remarkable characteristics of execellent performance,convenient operation and long service life.
