阀门如何翻译？ 引自 http:///xomox/htd ... d/046/features.html no cavities. no contamination. there are no body cavities where flow media can accumulate and contaminate subsiquant processing. the cavity-free design also prevents sticking. 从这里看应该说的是阀体没有介质会积累在这里或者弄脏下游管道的空腔，阻止粘结，当然我理解的可能不对。 superior, long-lasting in-line sealing. the inert ptfe sleeve completely surrounds the plug. the sleeve provides a large, circumferential sealing surface from port to port. open, closed, or rotating, the seal is assured. no ball or gate valve can match this sealing power. 这里说的是密封性非常好，可以长时间在线密封。 结合楼主说的需要移除设备上的部分还有取样，我认为业主还是要求密封性好，叫做无腔阀门或者零泄露阀门会更合适。 http://www.az-armaturen.co.za/ 上有更多的阀门样例，希望大家能了解一下。查看更多
