trim, trim package, release trim是什么意思? 楼上的意见不敢苟同。如果是valve trim,当然应理解为阀内件。但根据楼主提供的原句的结构来看,valves, trim, trim package, release trim应是并列的。但具体该怎样翻译,我也没有好的办法。 在此提供一段相关背景,供高人指点 the trim of this deluge system includes the basic trim package and the dry pilot trim package. the packages provide all of the fittings, nipples, valves and gauges that are required. variation from the listed trim configuration is a violation of the listing. the basic trim, also referred to as wet pilot trim, provides water flow alarm connections, diaphragm water supply connection, deluge valve drain, and manual pull station. the dry pilot trim package includes a pneumatic actuator, air pressure gauge, outlet for the low air supervisory pressure switch and associated nipples and fittings.查看更多
