摘要
研究阐述了透气阀结构及工作原理,并以DN200型高速透气阀为例,设计了透气阀实验使用系统及实验方法、步骤,揭示了透气阀的压力-流量特性。研究结果表明:正压阀开启压力为14.1 kPa,正压阀关闭压力为10.0 kPa;真空阀开启压力为-3.5 kPa,真空阀关闭压力为-2.6 kPa。正压阀瞬间的排气速度高达42 m/s,符合各船级社规范、SOLAS公约和IMO规则对应的章程条款要求。同时发现:透气阀设定压力通常设定正压阀为14.1~21.4 kPa、真空阀为-3.5~-7.01 kPa范围内,在规定值内即阀瓣起跳。
This paper describes the structure and working principle of the P/V valve,And take DN200 the P/V valve as an example,The experimental system,method and procedure of the P/V valve are designed,The pressure flow characteristics of the P/V valve are revealed.The results show that the opening pressure of the positive valve is 14.1 kPa,and the closing pressure of the positive valve is 10.0 kPa.The opening pressure of vacuum valve is-3.5 kPa,and the closing pressure of vacuum valve is-2.6 kPa.The instantaneous exhaust velocity of the positive valve is up to 42 m/s.Comply with the rules of each classification societies,SOLAS convention and IMO rules.At the same time found:the P/V Valve set pressure,usually set the positive Valve for 14.1~21.4 kPa,and vacuum valve for-3.5~-7.01 kPa range,Within the specified value,that is the valve disc jumps.
