偏心旋转阀：具有机械创新的精确流量控制

一个偏心的旋转阀，也称为偏心塞阀或旋转控制阀，是一种专门的流量控制装置，旨在平衡工业过程中的精确度，耐用性和效率。它独特的怪异设计使其与传统阀门不同，非常适合需要密封，低扭矩操作以及在具有挑战性的环境中可靠的性能的应用。

1。 设计基础：怪异原则

偏心旋转阀的定义特征是阀轴和插头（或圆盘）中心线之间的偏移（偏心）对齐。该设计创造了两个关键优势：
  1. 减少摩擦：偏心偏移可确保仅在旋转的最后阶段插头接触座椅，从而最大程度地减少磨损和摩擦。
  2. 机械楔形：随着插头的旋转，偏心的几何形状会产生一个密封力，该密封力会随着压力增加而收紧，从而增强了关闭性能。

关键组件：

  • 插头/圆盘：通常是椭圆形的或球形的，由不锈钢，合金制成或涂有耐磨性材料（例如，碳化钨）。
  • 座椅：用于多功能密封选项的金属对金属或软（PTFE，弹性体）。
  • 偏心轴：将插头连接到执行器，以最小的扭矩传输旋转运动。
  • 阀体：由碳钢，不锈钢或外来合金制成，可耐腐蚀。
