弹簧球止回阀 · 轴向阀芯剖示: assembly preview

What is it made of?

01 剖切阀体

不锈钢

半圆薄壁展示实际内部导向腔与上下贯通孔。

02 环形阀座

不锈钢

孔半径0.24,球半径0.34;球面与座口形成环形接触。

03 止回陶瓷球

陶瓷

轴向抬离阀座;无绕轴旋转开孔。

04 回位压缩弹簧

弹簧钢

下端接球体上侧,上端固定在透流导向架;受压时真实缩短。

05 开孔弹簧支承架

不锈钢

中央弹簧座与四根辐条支撑,周围开放供流体通过。

06 进出口端口

不锈钢

上下均为真实环孔,未以实心圆柱代替流道。

How do the parts work together?

顺流推开球体,弹簧随升程缩短;回位后球面与阀座的环形边接触。

确定性组件运动示意;非流体、受力或安全性能仿真。
