阀门 fámén valve (mechanical)
怎么记住“阀门”: 阀 valve + 门 door = valve (mechanical).
汉字
用法
- The mechanical valve that controls flow of fluid or gas - 关闭阀门 (guānbì fámén) to shut the valve.
- A concrete engineering/plumbing term; 阀 alone rarely stands for the valve in speech, so 阀门 is the everyday word.
- Don't confuse 阀 here with its other sense in 军阀 (jūnfá, warlord) / 财阀 (a powerful clique).
