# D型活塞杆密封圈，挤出成型

> 派克的挤压成型D形圈径向密封平面内径和加工外径。平基底有助于防止螺旋旋转失效,可以在径向密封应用中在安装过程中可能发生扭转的地方。

## 系列介绍

D形环密封(或D形环)是由平板底座和一个圆形的密封面另一种风格的均匀径向密封组成的，创建一个横截面几何形状类似于一个“D”。 这些密封使用在非常相似的双斜切密封的应用中,大多是在静态和往复式应用。D形圈密封还在槽中提供卓越的稳定性并可以在径向密封槽中帮助有效降低螺旋失败。 D型圈的圆形表面对于双斜切设计需要类似的安装力,并通过提供一个逐步压缩结构而顺利运转。我们也建议使用安装斜面使D型圈缓解安装力和保护密封。
