阀门

• 拼音: fá mén
• 汉字拆解: 阀 = 门 (door/gate) + 伐 (to cut/strike) — a gate mechanism that can cut off flow; 门 = pictograph of a double-leafed gate — door, gateway, valve

含义

Valve; a device that controls the flow of a fluid or gas through a pipe or conduit by opening, closing, or partially blocking it.

Used in engineering, plumbing, industrial, and metaphorical contexts. Figuratively, 阀门 can describe any mechanism that regulates the flow of something — information, emotion, resources — making it useful in policy and analytical discourse.
