往复式真空泵环状阀的设计

Design of Annular Valve of Vacuum Pump of Reciprocating Type

分析了往复式真空泵用环状阀与往复式压缩机用环状阀的不同之处,并从降低能耗、保证气阀使用寿命、提高真空度三方面去考虑环状阀的设计.

This paper analyses the difference between the annular valve of reciprocating vacuum pump and that of the reciprocating compressor. Design of annular valve is considered from three aspects: reduction of energy loss, insurence of operating life of the air valve, rasie of vacuum level.
