阀门模型系列-蝶阀 valve model series--butterfly valve

阀门，工业中的重要元件，它可以控制流体的开闭和流量。

Valves are important components in industry that can control the opening, closing, and flow of fluids.

这个系列是一个小系列，我设计了一些阀门的简易可动剖面模型，意在有些教育作用。

This series is a small series, and I have designed some simple movable sectional models of valves with the intention of providing some educational value.

蝶阀，一种阀体重要部件为片状的阀门，其结构简单，用料节省，使用便利，但因为叶片直接受到流体冲击，需要减速机构来保持阀门位置

Butterfly valve, an important component of the valve body that is a sheet-like valve, has a simple structure, saves materials, and is convenient to use. However, because the blades are directly impacted by the fluid, a deceleration mechanism is required to maintain the valve position
