堰板

A weir is a barrier installed in trays to control material flow, separation, or distribution in industrial processes.

技术定义与适配语境
典型 堰板 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A weir is a precision-engineered component typically integrated into trays, sieves, or valve assemblies to regulate the flow, depth, or distribution of materials (liquids, powders, granules) by creating a controlled overflow or barrier. It ensures uniform processing, separation efficiency, and process stability in applications like screening, sedimentation, or dosing.

定义
A weir is a precision-engineered component typically integrated into trays, sieves, or valve assemblies to regulate the flow, depth, or distribution of materials (liquids, powders, granules) by creating a controlled overflow or barrier. It ensures uniform processing, separation efficiency, and process stability in applications like screening, sedimentation, or dosing.
工作原理
Operates by creating a physical barrier at a specific height within a tray or channel. Materials flow over the weir's crest, with the overflow rate determined by the weir's geometry (e.g., notch shape, height), allowing for controlled separation, metering, or distribution based on fluid dynamics or particle size.
材料
Stainless steel (AISI 304/316 for corrosion resistance)aluminum alloys (for lightweight applications)engineered plastics (e.g.PTFEUHMW-PE for chemical inertness)or coated metals for abrasion resistance.
Height
10-200 mm
Length
Custom to tray width
Tolerance
±0.5 mm
Notch Type
Rectangular, V-notch, or Cipolletti
Surface Finish
Ra ≤ 1.6 μm
标准
ISO 14122-3DIN 19569
